The invention relates to the field walk-through valves for liquids and can be used in domestic water columns, street, basement, drinking fountains, irrigation systems.

Known valve, valves, in which case the input and output channels are placed two shutter associated with the rod that is moved by the actuator (C-ka No. 2003133672, EN). Also known valve for water supply networks, including the housing, the piston rod shut-off valve stop, a nozzle attached to the housing for movement and fixation with holes to release the water (h-ka No. 93025824, EN). The disadvantages is the inability to operate these valves at low temperatures.

The closest in technical essence is a valve with a metered flow of fluid in the body which freely with the gap set stop valve, and a casing provided with inlet and outlet pipes. The valve is provided with a stem on the valve when the rod is installed in the hole of the locking member passes coaxially through the nozzles. The valve is installed on the saddle, made the shut-off body with the possibility of release of fluid from the cavity above the pipe, provided with a valve tip established with the possibility of overlap. In another embodiment, the valve stem is installed in the chassis, equipped with bypass AC is crimson with messages cavity above the shut-off organ with pipes. When pressing on the valve stem communicates the cavity above the shut-off body. The fluid pressure locking body rises, opening the pipes. After releasing stem closes the valve, a stop valve slowly lowered due to the throttling of the fluid through the gap, which ensures the dosed delivery of a liquid and automatic closing of the valve (No. 92004185, EN). The disadvantage is unreliable operation of these valves at low temperatures.

Object of the invention is the extension of consumer opportunities valve, simplifying its design, improving the reliability.

The technical result of the invention is to eliminate summersemester devices at low temperatures.

The technical result is achieved in that the valve water shut-off includes a housing containing a coaxially arranged threaded insert, tightly shrunk into each other couplings of different diameters, tube valve, containing a through hole placed in it with the possibility of axial movement of the valve stem and thrust tube, the spring-loaded rod of the strut with one hand and the fixed thrust ring with the other, and the valve stem, made in the form of a hollow tube with a plug on the end, limited sleeve, through resistant insert is connected to the disk representing the shut-off valve and the hydraulic chamber, which is formed between the sleeve of smaller diameter and a threaded insert in the sleeve of larger diameter, while in the lower part of the valve stem and thrust tube is made above the cuff one or more holes and the center hole of the thrust tube coaxially located above the center of the holes on the valve stem. And the cross-sectional diameter of the holes of the valve stem must be less than or equal to the diameter of the inner section of the valve stem. The drive sleeve, the retaining ring is made of rubber material or silicone, and a threaded insert configured to connect to the water line.

Shut-off valve in the form of a disk is working for the water supply to the riser for water and drain it that prevents freezing on the surface at low temperatures. In addition, the valve allows the discharge of water from the riser into the space between the valve stem and the tube valve, which also contributes to the reliable operation of the device.

The invention is illustrated by drawings, there is shown valve water shut-off, 1 - in General, figure 2 - off, 3 - in working condition.

The proposed valve water shut-off consists of a housing containing a coaxially arranged threaded insert 1, which is tightly shrunk into one another clutch 3 smaller diametre sleeve of larger diameter 2, the tube 4 of the valve. Tube 4 valve includes a through hole placed in it with the possibility of axial movement of the stem 6 of the valve and the thrust tube 5, spring-loaded by means of a spring 15 through the thrust washer 19 stem riser 8 on one side and the fixed thrust ring 16 on the other. The stem 6 of the valve is made in the form of a hollow tube with a cap 12 at one end, limited sleeve 15 with the sealing ring 14, which is fixed retaining ring 13. Through hard insert 11, the rod 6 is connected with shut-off and by-pass valve in the form of a disc 10 which covers the entrance to the hydraulic chamber 9. Hydraulic chamber 9 is formed between the clutch 3 of smaller diameter and threaded insert 1 into the coupler 2 of larger diameter. In the lower part of the stem 6 of the valve and the thrust tube 5 is made above the cuff 15 one or more holes and the center hole 18 of the thrust tube 5 is coaxially above the center hole 17 of the stem 6 of the valve. The cross-sectional diameter of the holes 17 of the stem 6 of the valve must be less than or equal to the diameter of the inner section of the stem 6 of the valve. The disk 10, the sleeve 15, the retaining ring 16 made of a rubber material or a silicone, and a threaded insert 1 into the coupler 2 is configured to connect to the water line.

Valve water shut-off is as follows.

In the closed position (figure 2) the stem 6 of the valve with the cap 12 at one end fitted tightly, with the end of the insert abuts the sleeve 15 with the sealing ring 14, which block the access of water into the tube 4 of the valve and biased retaining ring 13. In this position the valve allows the discharge of water from the riser into the space between the stem 6 of the valve and the tube 4 of the valve. Through holes 17 of the rod is draining into the space between the thrust tube 5 and the tube 4 of the valve.

From the position "closed" by clicking on the riser 8 is a compression spring 15 with simultaneous supply of fluid from the water supply line to the valve body (figure 3). When the rod 6 with the cap 12 through the thrust box 11 provides a forced opening of the shut-off and bypass valves in the form of a disc 10. The holes 17 in the stem below the cuff 15, which provides a supply of fluid through them to parse. And through the holes 18 of the thrust tube, the fluid flows freely between the stem 6 of the valve and the tube 4. For mechanical return used spring 15 which is not in contact with water and with appropriate anti-corrosion treatment significantly increases its service life. When removing the load, the spring 15 returns the valve in the closed state. This system is more suitable for outdoor water taps, drinking fountains, etc.

In the absence of this spring mechanism at a pressure of less than 4 kgf/cm2not provide the supports return to the closed state (for certain purposes water - irrigation, car wash, etc - it's convenient). Closing is done by jerking the rod up manually a little effort.

All connections to stationary parts are sealed and non-separable. In the case of repair of a valve vyrisovyvaet of the riser and change to another (i.e. repair it not to be). In areas where the liquid may be sand and suspended solids, it is recommended to put the coarse filter. The valve of the proposed design may be used in a wide temperature range from -60C to +70C at an operating pressure of 15 kgf/cm2.

Thus, the claimed invention through the combination of essential features set forth in the formula to achieve the desired technical result.
