Abstract
The utility model relates to a device which can automatically close a water channel when water supply is cut off. The technical scheme of the device is as follows: a valve core is arranged between a water inlet and a water outlet of a valve body; when the water supply is cut off, as no pressure exists in a pressure cavity, the valve core leads the device to be in closing state under the function of a spring. When the water supply gets right, as the closing function of the valve core, water pressure cannot transmit pressure to the pressure cavity by a pressure-transmitting hole, the valve core does not act, the device is still in closing state, and water is not allowed to flow out. When the water supply gets right, an opening handle is pulled to drive the valve core to move, so as to open the water channel; meanwhile, water pressure acts the pressure of water on an elastic rubber pad by the pressure-transmitting hole, the valve core is kept at the position under the function of the pressure, and a system restores to the normal state.
Description
1, affiliated technical field
The utility model relates to a kind of being installed in the water supply pipe, is implemented in the device of closing pipeline under the situation of cutting off the water automatically, when coming water again after can guaranteeing to cut off the water, even water tap can not there are flowing out in opening state yet, plays energy-conservation and safe effect.
2, background technique
At present, in water-supply systems, the phenomenon of cutting off the water happens occasionally.Often the user forgets and closes water tap, and when water system resumed water supply, water can flow out automatically, causes waste and " flooding " phenomenon.The present invention can address this problem.
3, summary of the invention
In order to overcome the problem described in the technical background, the utility model provides a kind of device that can close pipeline under the state of cutting off the water automatically.
The technological scheme that its technical problem that solves the utility model adopts is: a spool is installed between the water intake of valve body and water outlet, and this spool plays the effect of a switch.Under state appearred temporarily cutting off the water in water system, because no pressure in the pressurized chamber, spool made device be in closed condition under the effect of Returnning spring.When water system resumes water supply, because the closing function of spool, make hydraulic pressure not give resilient rubbber cushion in the pressurized chamber with propagation of pressure by pressure transmission hole, spool stays in situ, device still is in closed condition, has guaranteed under the water tap opening state anhydrous outflow.After coming water, only need draw and open handle, this moment, spool was under manual effect, to install the water route opens, have the water of pressure to give resilient rubbber cushion by pressure transmission hole with propagation of pressure simultaneously, the resilient rubbber cushion pressurized produces displacement, and the drive spool moves and makes water intake and water outlet be in channel status, and keeping this state, system recovery normally uses.
The beneficial effects of the utility model are, can guarantee that water system temporarily cutting off the water and forgetting that when closing water tap, after system recovery supplied water, water can not flow out once more, play and put and end to waste and the effect of " flooding ".
4, description of drawings
Accompanying drawing is a structure principle chart of the present utility model.
1. water intakes among the figure, 2. valve body, 3. pressurized chamber, 4. spool, 5. pressure transmission hole, 6. water outlet, 7. water tap, 8. safety cover, 9. resilient rubbber cushion is 10. opened handle, 11. Returnning springs.
5, embodiment
Water intake (1) and water outlet (6) are a through hole in the accompanying drawings, and its two ends are used to connect water pipe and water tap for connecting internal thread.Process a spool pilot hole along the through hole vertical axis, be used to install spool (4), play the water route switching function.Resilient rubbber cushion (9) is plane corrugated shape rubber product, is used to drive spool (4) motion.Pressure transmission hole (5) is a passage of connecting water outlet (6) and pressurized chamber (3), is used for hydraulic pressure is passed to resilient rubbber cushion (9).
In force; with spool (4); resilient rubbber cushion (9); Returnning spring (11) after unlatching handle (10) is assembled into sub-assembly, is fixedly mounted on this sub-assembly between the water intake (1) and water outlet (6) of valve body (2) with safety cover (8); it is connected with valve body with screw; be assembled into final product, in use, it be installed in the delivery (pipe) line in the serial connection mode.The area of resilient rubbber cushion (9) should be able to guarantee under water tap is in opening state, and the pressure that its pressure transmission hole passes to the pressurized chamber multiply by its area and is compressed to elastic force under the ultimate state greater than Returnning spring (11).
Claims (2)
1. the self acting stop valve of cutting off the water is serially connected in resident's indoor Pipeline, it is characterized in that a spool is installed in valve body, is used to control the Kai Heguan in water route.
2. the self acting stop valve of cutting off the water according to claim 1; it is characterized in that: spool (4), Returnning spring (11), resilient rubbber cushion (9) and unlatching handle (10) are assembled into a sub-assembly; with safety cover (8) this sub-assembly is fixedly mounted between the water intake (1) and water outlet (6) of valve body (2), between pressurized chamber (3) and water outlet (6), a pressure transmission hole (5) is arranged.
