🛠 water pressure regulator: purpose and types

To stabilize the water supply system or heating, It is necessary to provide in its loop water pressure regulator. This functional device to protect line from the adverse factors and reduce the amount of fluid consumed. We offer to meet with the existing species and their distinctive features.

Intended use

To stabilize the operation of household appliances requires not only constant voltageBut also the pressure in the system. With insufficient water pressure washing machine or water-heating boilers can not quite work correctly. To avoid this, set knob "behind" providing equalization of water pressure supplied to the end user.

There is also a regulator "to myself." Its main purpose is to protect the home appliances and pipe overpressure and water hammer. These products are installed in heating systems to maintain their performance.

regulator not only performs protective function. When it is installed in the water circuit of the system can optimize their water costs.

Attention! According to some estimates, setting of the pressure regulator reduces the amount of water consumed by 20-25%.

The apparatus and operation of various types of water pressure regulators

The design of a particular unit has a significant influence on its operating principle. We offer to meet with the main varieties, so you can make a choice in favor of a certain type of regulator.

Piston and diaphragm

a piston-type apparatus has a simple structure. For pressure control is used a spring loaded piston of a small size. Due to its motion, it becomes possible to increase or reduce the cross-section line and thus equalize the pressure in the system. Squeezing and relaxing a spring with the regulating screw, it becomes possible to set a fixed water pressure at the outlet.

Because of sensitivity to the quality of the transported fluid, such regulators should be installed complete with in filters for water purification. Otherwise, there is a risk of jamming the piston. Given this fact, modern devices are equipped with filter elements.

Membrane regulators are more reliable design concept. Their structure includes a spring-loaded membrane located inside the sealed chamber. The resulting pressure acts on a spring which is connected to a special valve. As a result, the capacity of the device increases or decreases.

Automatic and electronic

The design of the automatic models close to the piston regulators. However, in this case, the role of piston performs a membrane, and the spring is connected to the flap. Once water pressure begins to rise, the membrane begins to move upward, carrying the flap. As a result, the cross section partially overlaps, and the pressure is reduced. After reaching the desired level of pressure in the system, the membrane together with the flap is returned to its original location.

When reducing the pressure of the incoming flow membrane is lowered by omitting the damper. flow hole is opened and the discharge pressure increases. Due to the presence of the second spring on the valve, automatic models can accurately adjust the device settings. For this purpose a special screw.

Electronic controllers provide the most accurate control, and therefore have a relatively high cost. They can set "before and after itself." A sensor measures the pressure at the inlet to the system and sends a signal to the control device. The latter gives the team locking mechanism.

flow

In this type of regulators no moving parts. It guarantees them a long life and a sufficient level of reliability. The particular internal configuration of the device provides reduced water rate which begins to run slower. May be used irrigation systems.

Choosing a water pressure regulator

To become the owner of the device with the optimal functionality, it is necessary to competently approach to the choice of model. Offer to meet the basic criteria, focusing on that, you can buy the device, ideally suited to the particular water system.

by design

Choosing between the piston and the membrane structure, should prefer the second type. They are more reliable in operation, although the products of the first type piston wear is minimal. Piston structures are quite sensitive to the quality of water flowing through the pipeline. Even a small sand particle piston may jam.

The membrane type is not increased demands for service. Due to their design, excluded contact with water. Therefore, there is no fear of corrosion processes. The only weak point is a movable diaphragm.

Attention! Preferring diaphragm type regulator, can provide a stable operation of the water supply or heating systems.

Specifications

When selecting a suitable regulator must be remembered that each product is designed for a certain pressure on the inlet and outlet. When determining the required technical parameters, consider characteristics equipmentInstalled in a house or apartment. From this data, define specifications regulator.

Besides pressure, consider the degree of heating water to be circulated through the water supply. If the device is designed to operate at a temperature of from 0C to 40C, to connect it to the hot water supply system, and heating it is impossible. In such conditions can work model designed for operation at temperatures up to 130 ° C.

In material manufacturing

To ensure long-term operation of the regulator is to choose products for the manufacture of which were used high-quality alloys with good corrosion characteristics. Manufacturers offer such products in bronze, brass and steel. As part of the latter contains elements that improve its corrosion resistance.

Tip! Not to be mistaken with the choice, it is not necessary to purchase a cheap reinforcement. For the manufacture of such products, most likely to use poor-quality raw materials.

Leading manufacturers and rating of popular models

Despite the large range, some models are popular. We offer to meet with some of them. Perhaps some devices you may be interested.

Honeywell D04FM: Rating 5/5

Installation and adjustment of the water pressure regulator

For the device to effectively cope with the tasks assigned to it, it must be properly installed and adjusted. We offer to deal with how this can be done, depending on the installation site.

In the apartment

Installation work in the apartment are performed as follows:

Illustration	Procedure
	We prepare everything you need: the controller, adapter, flax and sealing paste. Also, for keys will be needed.
	The flat closes the water. By riser successively dispose the ball valve filter. For an installation site must be connected to the accounting system of the instrument.
	On a seat on account of the instrument we wind flax and causes sealing paste.
	Screw the gearbox to the accounting unit.
	Screw flax on top of the controller, causes the sealing paste and, via an adapter device to be connected to the second seats. Perform adjustment gear, turning the adjusting screw until the pressure until the required value is received. All points of water intake at the same time should be closed.

In a private house

Regulator in a private house has the same function as in the apartment. Positioning device should be in place to connect the home of the water supply system to the general pipeline. More details about the connection procedure can be found in the following video:

Maintenance of water pressure regulators

Maintenance of these devices is a timely control of the pressure condition in the system. If the setting for some reasons is impossible, it is a clear indication that the regulator is faulty. In this case, it should be removed, repaired and reinstalled or replaced.
