After adopting said structure, water outlet place in the water supply chamber connects the upper water-out pipe, be connected with intake pipe on the water-inlet cavity, winter is during villager's water, thereby can screw valve rod makes water-inlet cavity be communicated with the water supply chamber and water supply chamber and drain chamber are ended, under this state, can pass through water-inlet cavity, water supply chamber until outlet pipe from the water of intake pipe, thereby finish normal water supply; Screw valve rod make water-inlet cavity and water supply chamber by and the water supply chamber is communicated with drain chamber, no longer water supply at this moment, the part water that retains in the water supply chamber can pass through the drain chamber emptying, thereby the Shi Buhui that is cold freezes water pipe or valve.In sum, the utlity model has the advantage that can not freeze valve on water pipe or the water pipe.
Described valve rod is provided with upper sealing panel and lower seal portion, and lower seal portion cooperates with drain chamber inwall liquid sealing, also is provided with tank on the valve rod, and top, the terminal point that the starting point of crossing tank is positioned at upper sealing panel is positioned at the top of lower seal portion.
Described valve body was provided with water cavity, crossed the corresponding position of water cavity bottom and water-inlet cavity connection, top and upper sealing panel and was provided with water passage hole, and the mistake water cavity is communicated with the water supply chamber by water passage hole.
Described lower seal portion comprises and is arranged on the annular groove on the valve rod and is installed in seal ring in the annular groove.
The top of described valve rod is screwed onto on the valve body and stretch out outside the valve body at its top, and the overhanging end of valve rod is connected with handwheel, and the top of valve rod cooperates with the inwall liquid sealing in water supply chamber.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of the utility model user mode.
Embodiment
