Abstract
The utility model relates to a device which can prevent the water supply valve from running water when water supply is cut off. The utility model aims to prevent the phenomenon of water running caused by the water supply valves is not closed by the user's negligence when the water supply of the water supply system is cut off. The utility model provides an automatic closing valve when the water is cut off, which comprises a water supply valve and is characterized in that the front portion of the water inlet cavity of the water supply valve is provided with a switch valve connected with a float by a connection rod. The lower portion of the float is provided with a push rod pushing the float. The sectional area of the valve opening of the switch valve is larger than the sectional area of the valve opening of the water supply valve.
Description
The utility model relates to a kind ofly can prevent the device that water supply valve is metalled run out when stopping to supply water.
In water system, the frequent appearance phenomenon of cutting off the water for some reason is when this phenomenon takes place, after the water user opens water supply valve (as water tap) and finds to cut off the water, often, forget and close water supply valve, so following accident will take place: when resuming water supply after a while owing to careless, because the water user goes out, or, will cause the phenomenon of metalling run out away from water supply valve, except wasting a large amount of water, also may increase many worries to people because sewerage stops up or circulation does not freely cause flood.
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of self acting stop valve of cutting off the water is provided, and when stopping to supply water, closes water supply valve even water user's carelessness is forgotten, also can not cause the phenomenon of metalling run out.
The utility model can be realized by following measure:
Water-inlet cavity front at water supply valve (as water tap, stop valve etc.) mouth has one by connecting rod and the cursory switch valve that links to each other; Below cursory a push rod is arranged, this push rod is used to promote cursory moving up, so that open switch valve; The valve port net sectional area of switch valve is greater than the net sectional area of water supply valve valve port, to guarantee always to be full of water between the water-inlet cavity of water supply valve and the water chamber of switch valve when supplying water, makes cursoryly to allow switch valve leave its valve port all the time by buoyancy of water; When stopping to supply water, after the water user opens water supply valve, support that at the water-inlet cavity of water supply valve cursory a part of water flows out from water supply valve, cursoryly lose buoyancy of water, move down by deadweight, close its valve port with the cursory switch valve that links to each other, be cut off between supply channel and the water supply valve.When resuming water supply, even water supply valve is in opening state, the water in the pipeline can not flow out from the water supply valve port yet again.As long as the water user plans water, if water supply valve just was in closed condition originally, because the water that its water supply valve ante-chamber keeps is supported cursoryly upwards to make switch valve be in opening state always, the water in the pipeline can flow out from water supply valve by its switch valve port; If water supply valve is in opening state, then upwards promote push rod, force cursory drive switch valve to leave its valve seat, do not cross a few second water and just be full of space between water supply valve and the switch valve, float cursory, make switch valve be in opening state.
The utility model can also be realized by following measures:
Above cursory, an erosion control cap that is fixed on the switch valve valve body is arranged, make current in the supply channel when switch valve, flow the water-inlet cavity of water by the top inflow water supply valve of erosion control cap, it is cursory so just can directly not impact, thereby can design smallerly cursory, reduce the cut off the water size of self acting stop valve of the utility model.
Description of drawings is as follows:
Fig. 1 is the cut off the water structural representation of self acting stop valve of the utility model.
In conjunction with the accompanying drawings the utility model self acting stop valve of cutting off the water is described in further detail now:
Among the figure 1 is water supply stopcock (can certainly be other stop valve), front at water tap water-inlet cavity 2, there is one by connecting rod 3 and cursory 4 switch valves that link to each other 5, cursory is the rubber bag tank of hollow or the plastics of plastic bag or foaming, switch valve is plane (also can be taper certainly), the rubber pad 7 that seals is equipped with at the contacted position of valve and valve seat, the lid 8 that links to each other with pipeline is contained on the wall above the switch valve, the erosion control cap 9 that is umbrella is fixed on below the switch valve seat, have and promptly seal and have the T type push rod 11 of the stuffing box gland 10 of reset response to be contained on the wall that is positioned at cursory below, and be fixed with the screw plug 12 that T type push rod is passed in a centre.When upwards promoting push rod and hold up when removing its thrust after cursory, push rod resets it by the recuperability of stuffing box gland.
The utility model compared with prior art has following advantage:
1, when water system stops to supply water, even forgetting, the water user closes water supply valve, the switch valve in the utility model auto-close valve for cutting off water also can cut off the path between supply channel and the feed water valve automatically, has prevented the phenomenon of metalling run out, and can not cause flood.
2, the utility model auto-close valve for cutting off water is simple in structure, it is easy to use: if water system has stopped water supply, and feed water valve is opened, water user after resuming water supply also slightly stops a moment as long as upwards promote push rod 11, switch valve just is in opening always, and water can flow out from feed water valve continually.
Claims (2)
1, a kind of self acting stop valve of cutting off the water, it comprises water supply valve 1, it is characterized in that: in the front of the water-inlet cavity 2 of water supply valve, have one by connecting rod 3 and cursory 4 switch valves that link to each other 5, there is the cursory push rod 11 of a promotion cursory 4 below; The valve port sectional area of its switch valve is greater than the sectional area of water supply valve valve port.
2, the self acting stop valve of cutting off the water according to claim 1 is characterized in that: have one to prevent that current from directly impacting cursory erosion control cap 9 above cursory 4.
