Modern industry produces a great variety of taps and valves for controlling fluid flow. For every application can be found suitable. But inquiring minds house masters are not abandoned their attempts to develop and implement their own design. Sometimes it is caused by the desire to save money, but chasche- desire to test their own strength as a designer, machine builder, mechanic and electrical.
types of cranes
Trying to repeat structure of a conventional shut-off valve is of no practical and economic meaning if the home shop is not equipped with precision milling, turning and drilling machines. The price of industrial designs for mass production is available even the most modest budget. Another thing-technically demanding shut-off valve for special applications, such as:
- Ball Electric;
- needle;
- ice-free;
- instantaneous heaters;
Options to implement them with their own hands will be discussed below.
Ball Electric,
The motorized valve can find application in modern "intelligent" systems of water supply, heating and Air conditioning produced household masters with minimal use of standard components. In addition to checking their forces, there will be a substantial monetary vygoda- a purchased unit with electric costs from 2 to 10 thousand. rub.
For ball valve with mounted electric made by their own hands, you need the following materials and components:
- Ball valve 3/4 ";
- window lift drive for LADA 1117 2123 Left LSA;
- Relay automotive five-pin - 2 pcs .;
- end mikrovyklyuchateli- 2 pcs .;
- tin sheet of 1 mm thickness (for frame and clamps);
- steel tube 10 mm- cutters (for sleeves);
- profile square 10 * 10 mm-10 cm;
- band steel 4 mm tolschinoy- 10 * 1 cm;
- spring 12 mm diameter;
- bolt M8 * 45 with nut and shaybami- 2 pcs.
All electrical equipment is 12 volts. Of the tools needed:
- drill;
- Metal scissors;
- work bench with vise;
- welding machine;
- Manual bench tools (hammer, screwdriver, wrench, pliers, etc.)
Generated control mechanism should allow electrical as the crane via the actuator or manually. manufacturing sequence is as follows:
- Bend a U-shaped frame made of sheet metal.
- Of the segments of the tube to make the sleeve to drive with marked window to the frame.
- Secure the drive.
- A frame mounted on nozzles, leaving the ball valve, with hose clamps.
- From the square profile cut in the nozzle reducer axle.
- Welded to her band.
- From the strip and assemble the handle lever drive mechanism is spring-loaded it. The spring presses the lever to each other, if necessary, they can be quickly disconnect without tools and manually operated crane.
- Lane pivotally fasten to the handle by means of bolts and nuts. Lock the nut.
- Square profile window mounted on the gear shaft.
Next should be tested kinematics, applying voltage to the motor. You can use a car battery or power supply capacity of not less than 50 watts. Linkage should move smoothly, without jerks and distortions. If necessary, correct touch each other details file.
Now the turn electrical actuator.
- In the extreme positions of the handle mount terminal microswitches.
- They should be connected in such a way that they trip relay control circuit, which is enabled through the motor, on reaching the end position "open" or "closed."
This drive can be connected to the control circuits of the system of "smart home". Elektrokran water, made with their own hands will be cost effective if the power window drive will get inexpensive. New stands up to 1 thousand. rub., and can eat half the economy.
Instead, the drive window, you can use any other electric,
similar in power and torque.
Needle
The needle valve with a large adjustment range can be assembled from readily available materials at low cost. For its production will require:
- Plastic disposable syringe 2 ml.
- Insulin syringe of 1 ml.
- Ball bearing - 2 pcs.
- Springs- 2 pcs.
- A nut and an adjusting screw.
- Epoxy adhesive.
- Fasteners.
- Plastic cable ties, 2 pcs.
In the diagram marked:
- Shpritsy- black.
- Shariki- blue.
- Springs- green.
- Rod red.
- The direction of movement zhidkosti- green arrows.
To make the crane should be:
- Choose balls in diameter. Large should be slightly less than the internal dimension of 2 ml syringe malenkiy- 2 times less.
- Pick up the force of the spring. large force compression spring is approximately twice larger than small.
- Drill a large syringe near the nozzle hole equal to the inner diameter of the insulin. Insulin syringe draw for ears ties, wrap synthetic thread and glue.
- Inserted into a large syringe and a small ball less spring.
- Cut off the stem of the piston.
- Insert the large spring and a second ball.
- Insert adjusting screw.
- Fasten nut screwed to the lugs.
The incoming fluid will tend to press the ball from the inlet, the spring will urge the back it is stronger, the stronger will tighten the adjusting screw. If the screw is fully vyvernut- stream will be free, if fully zakruchen- flow will be blocked.
ice-crane
Those who have a need to use the water supply in the area in the winter time, faced with the problem of street tap freezing. At large temperature gradients inside the water pipe fittings and turns to ice and may break them.
There are several ways of organizing such a water:
- Setting purchased ice-tap. There the valve disc is located inside the warm contour walls. Always place it with a slope toward the street. Then, after closing the valve remains in the pipe the water flows downward and does not freeze in the pipe. Devices are available of different lengths, which allows to set different from the thickness of the wall.
- Home-made version of such a device is a conventional poppet valve mounted on the cart within the warm path walls. His rod lengthened rod extending through the wall of the tube. Outside handle is fixed on the rod. Pipe must also be installed with a slope toward the street. This method requires extra holes in the wall, but it is several times cheaper. Of course, the need to periodically shear frost formed under the spout.
- Crane mounted on an underground insulated water pipe. In this case, one must have drainage, which will drain the water remaining after closing the tap in the vertical pipe. The three-way valve structure is used, mounted in insulated sump.
- The control valve from the street through the stem extension. In the working position, it consists in supplying water into a vertical tube, which is mounted on the end of the spout. Once the water is dialed, the tap is closed, the feed is stopped, and the remaining water in the pipe through a third tap hole is discharged into drainage.
Sensory
Full touch faucet handyman produce is unlikely to be a force. The main problem is in the distribution and waterproof infrared proximity sensor. Rather interesting design that can switch on and off the water with his hands occupied, it is possible to assemble using
- The solenoid valve of a washing machine to 220 v - 2 pcs.
- Choke 10mm * 1/2 -2 male thread pieces.
- Fittings ¾ to ½ int. rezba- 2 pcs.
- call button for surface mounting.
- Wires.
How to install and configure the following:
- A valve mounted in the fracture line hot and cold water immediately before the mixer.
- Drive them connected via footswitch.
- During pre-setting with open solenoid valves need to set the desired temperature and the intensity of the water flow and leave the mixer tap in this position.
- If necessary, turn on the water enough to press the key zvonka- valve will work and the water will flow out of the tap.
When water is no longer needed, it is sufficient to release the key, and the spring return valve in the closed state. Particular attention should be paid to waterproofing cables and connections.
Instantaneous water heater faucet
Purchased instantaneous electric water heaters have a compact design and are equipped with temperature control system, spout and aerator. Such a nozzle on the faucet to make their own hands in a home workshop is unlikely. The main problem lies in the accuracy of machining of parts and providing electrical appliance. However, diy developed a simple and very efficient design eliminates the need for complex and costly components. It works by heating teploobmennika- coil on a gas or electric burner. For the manufacture of enough secondary plumbing skills.
Of the materials and tools you need:
- Copper pipe diameter 10-12 mm-1 m
- Rubber or plastic, heat - distance from the burner 2 to the shell 1 m
- 2 fitting with the inner diameter of the hose on ½
- Adapter crane for cubic
- 4 clamp
- Bow and a threaded nut to nim- 2 pcs.
- Building a knife, screwdriver, pipe wrench
Work carried out in the following sequence:
- Navit of the tube spiral shape hotplate. Spiral offset the cone to make the most of the heat from the burners. The straight sections of the input and output pipe should go beyond the slab panels by 20-30 cm.
- Fix the plate to the spiral lattice. Wear hoses pipes and fix their collars.
- A fitting attached to the cold water inlet (pipe or canister valve), the other to the mixer.
- Wear loose fitting on the ends of the hose and also fix a collar. Cold water should flow to the lower pipe spiral.
When operating such a heater for a minute it can not be left unattended.
