Gidrostrelka: operating principles, purpose and calculations, installation

Owners of individual houses in the organization heating system familiar with the concept of imbalance after accession to the boiler circuit. To equalize the pressure and reduce it to boiler equipment gidrostrelka set. The principle of operation, the purpose of the calculations and we will discuss in this review.

The concept gidrostrelki

In a professional environment, you can meet other names gidrostrelki:

• hydraulic or termogidravlicheskiyrazdelitel;
• anuloid.

Application gidrostrelki recommended primarily for boiler equipment long series of combustion of the solid fuel rather than for gas.

The main purpose of the work of the hydraulic separator (it's official name gidrostrelki) - the separation of hydraulic flows. Contours divided channel, making them independent and autonomous with heat transfer medium by the heating system. Thus good heat is transferred from one circuit to another.

Gidrostrelka: principle of the purpose and calculations

individual heating system at home can consist of several subsystems. The implementation of each junction should be independent of pressure and flow of coolant for each function. Due to the fact that heat transfer agent comes from a single point, this results in unbalancing the individual circuits of the system.

In order to avoid such a situation, arranged gidrostrelki (anuloidy) in the heating system.

Main functions

In organizing the heat from the boiler for solid fuels, jet flows are heated boiler whose resistance is much less than in the basic system.

Part heating systems often included floor heating, bathrooms and kitchen. That is, one heat generator is connected to at least three consumers. Temperature conditions of each set individually, and thus has a different resistance heating decoupling. In order not to unbalance the heating system there, they should be combined.

It also is the basic principle of the low loss header. In other words, it divides the heating system into two independent circuits: the heat source and the common home heating, which includes all subsystems.

Important! In the presence of the heat source circuit is reduced or eliminated the influence of the contour on the overall system heat source.

Isolation of subsystems in the overall system is arranged on the same principle, they do not affect each other. Thus, the hydraulic hand solves the problem of balancing of boilers and heating systems.

Use separator is recommended when using it no pressure difference between the flow and return more than four hundredths of a meter water column. Inside anuloida exchanged hot water and cooled.

Job separator occurs in one of three modes:

• both circuits flows are equal. Behavior on properly selected pumps It occurs only when the simultaneous operation of all pumps, boilers and heating systems in the normal mode;
• the first flow path is significantly less than the second. Realization is possible only for those cases where a good enough job of just one boiler of the whole heating systems.
• a second flow path is significantly less than the first. Realization is possible when the suspended heat supply or heating is required only one zone.

Thanks to the work gidrostrelki, it is possible to control boiler equipment and the heating system of the house. Therefore, to save on its purchase and installation is not necessary.

Additional functions

In addition to protect the heat exchanger from heat stroke, gidrostrelka prevents the heating system from damage in the event of an emergency shutdown home water system, underfloor heating and other subsystems.

In addition, it serves as a clarifier for mechanical structures, such as scale and rust. Another important function, which is necessary in gidrostrelka heating system - removal of air from coolant.

The device gidrostrelki

Thermo-hydraulic separator - a trumpet, complete with welded into the housing 4 tailpipes. This is the most common model. The number of nozzles may be increased depending on the equipment heating systems.

Hydraulic separator may be circular or rectangular. The principle of operation is virtually identical to each other. The rectangular shape looks better. Round - is more appropriate from the point of view of the organization of hydraulics. But basically, the shape does not affect the organization of the system operation.

Further, in the composition may be incorporated gidrostrelki:

• filters;
• air separators diverting air masses;
• cranes;
• three-way valves thermoregulation with elements which prevent the ingress of cold water into the boiler return flow circuit;
• more thermal insulation;
• sludge trap;
• thermometer;
• manometer.

The housing of the hydraulic separator can be made of low-carbon, stainless steel or copper. Gidrostrelku also discharged from polypropylene. Additionally, it is processed by special corrosion-proofing compositions if necessary.

It should know! Gidrorazdeliteli of the polymer can be used for the heating system, which serves the boiler equipment with capacity of 13-35 kW. They can not be used for equipment operating on solid fuels.

The principle of operation of the hydraulic splitter

anuloida device is extremely simple. This is a small part of the pipe, on a section having the form of a square. heating system is distributed to the big and small contours. As part of the small circuit - Boilers and gidrorazdelitel. The Grand is included consumer - heating system.

When heat consumption boiler equipment equal to its generation in gidrostrelke fluid direction is horizontal. In the case of deviations in the generation / consumption, the coolant gets into the small loop, which increases the temperature before the boiler equipment. The boiler is automatically shut down, coolant continues to move to the temperature drop. After that heating equipment is switched again.

Now we know what to gidrostrelka heating system. It provides uniform heat flows in the circuits, guaranteeing their independent functioning.

design gidrostrelok

The design is no big deal. However, certain rules must be followed. Manufacturers offer models of various shapes and sizes. You can pick up the necessary product with characteristics easily. There gidrostrelki for heating, in which the combined operation of the separator and a collector for connecting circuit.

The high cost of factory production suggests the idea of ​​independent manufacturing gidrostrelki. To do this, you must have the basic skills welding and plumbing work. Main - is the observance of sizes to ensure the smooth operation of the product.

Consider the basic design of hydraulic separator:

Photo	types of structures
	Classical - operates according to the rule «3D» (three diameters). In the scheme shown and inner diameters of the passage, regardless of shell thickness.
	alternating nozzles. It is believed that the arrangement in the form of a step-down improves separation of gases, the separation step improves up of suspended solids.
	horizontal version gidrostrelki location with a different arrangement of pipes.
	Gidrostrelka a lattice. In everyday life you can meet the design of the sections radiator heating. Such a system needs additional insulation to prevent heat loss.

Gidrostrelka multiple contours

Using gidrostrelki necessary when multiple loops. This may be one of the prerequisites for the manufacturer to provide a warranty on the boiler installation and assembly work.

In private houses area of ​​200 square meters, which established the functioning of several circuits (warm floor, Bathrooms, kitchen), the use of hydraulic separator will increase the life of the boiler and pump equipment. In addition, make their functioning more smoothly, and thus economical.

Calculation gidrostrelki for heating

Manufacturers produce gidrorazdeliteli designed for a specific power of the heating system. For the self-production of a simple device, you must calculate the basic values ​​and make their own hands gidrostrelki drawings.

Method of calculation for the boiler output

For calculation It needs a single value - the diameter of the pipe or the separator. All other parameters are repelled from this value.

Calculations for gidrostrelkipo pravilutreh diameters. These can be taken from a passport on boiler equipment.

Method of calculation of pump performance

You can make payment based on the performance of pumping equipment. For this method, the initial parameters in the circuits of pumps boiler equipment and the entire heating system.

The calculation must perform in order to not overload the pumps boiler system, while ensuring the required flow rates for all the contours. In other words, the overall performance of the system higher than the pump pumping equipment propelling coolant through otelnye equipment.

D = 2 × √ ((ΣQfrom-Qcat) / (Π × V))where

Combination heating manifold gidrostrelkoy

To heat homes with a small area using the boiler with integrated pump equipment. The contours of the heating system are connected via hydraulic arrow.

In houses with an area of ​​150 square meters connection circuits is made through a comb which provides maintenance and operating systems.

Installation of the collector is made after the capacitive hydraulic separator. Manifold consists of two mutually independent parts which are combined webs. Nozzles bump pairs based on the amount of the secondary circuit systems.

All shut-off and control elements of the heating system installed in one location. Due to the increased diameter of the distribution manifold providing uniform flow of coolant between all circuits.

The collector together with gidrorazdelitelem forms a single hydraulic system module.

Important! Regulating valves fully maximizes flow and pressure of the coolant on all circuits. Balancing helps to achieve the calculated flow rates.

	Before starting the work it is necessary to prepare the following materials and tools 2 inch thread for the main circuit 6 and ¾ threads on the heating system circuit, a profile pipe 80 with a wall thickness of 3 mm, 25 inch pipe, Profile pipes 20 × 20 square washer 2 at the ends, two steel thread, welding machine electrodes, grinders, 2 metal crowns 25 and 29 diameter drill of 8.5 mm, fast-drying primer and paint hammer.
	Cut the square tube piece size 900 mm.
	Drill multistage preliminary hole drill according to a previously applied marks. On one side, the distance from the edge 50 × 150 × 150 × 200 × 150 × 150 × 50, on the opposite side of 325 × 250 × 325. That's enough for boilers using solid fuel.
	Holes 25 extend crown diameter. Similarly crown 29 provided with holes diameter.
	Ready holes in the pipe.
	Welded steel couplings washers
	At this stage, the clutch with plugs must be cleaned.
	Washer welded to the ends in 2 stages. First prihvatyvaet at several points, and then performs the basic welding seam. After that, all you need to clean up.
	By forming holes on the pipe thread are welded in a similar manner, after which the tube must be cleaned.
	At the end, the test process. For this purpose, all the threads are wound on the stub, and the system is connected to a pump with a pressure gauge, 7.2 atmosphere.
	After tests, gidrostrelku must be primed and painted. While the paint dries, you can prepare for mounting the separator.

This process can be clearly look at the master class of a professional:

Gidrostrelku manufacture of polypropylene with their hands even easier. This requires special tools for cutting plastic and special apparatus for welding.

Features gidrostrelki installation

Gidrostrelku install the boiler, in the presence of the collector - in front of him. Branch pipes are connected by means of flanges or threads in the following order: on one side of the separator is connected to the outputs in the order 1, 2, 3, on the opposite side a mirror order 3, 2, 1. It is not a dogma, depending on the conditions of the location of the junction pipe can vary.

The most frequently used vertical distributor. This is the most convenient location for screening suspensions of water flows. If conditions require, it can be positioned horizontally.

For fixing small models of the brackets can be used. Gidrostrelki Stir with a large weight on the floor or table, so as not to overload the system piping.

conclusion

So, now you know what it is: a hydraulic hand. In summing up, we can note its main advantage. It protects the heat exchanger made of cast iron from the heat and water hammer, simplifies the selection of pumping equipment, all equipment is operating normally. The heating system is balanced, circuits work does not affect each other.
