Abstract
The utility model relates to an automatic closing valve for preventing the water escape phenomenon, which is composed of a valve body, a sealing ring, a valve core, a pull handle for a valve plug rod, and a valve plug rod, wherein, the valve core is connected with the valve body via a screw fastener, the valve plug rod is connected with the pull handle for a valve plug rod via a screw fastener, and the sealing ring is installed on the lug boss of the valve plug rod. The sealing ring is arranged inside the groove of the valve core. When the water supply is cut off, the valve plug rod and the sealing ring can naturally fall on the valve body under the action of the gravity to clog a water flow passage; when the water is supplied again, the valve plug and the sealing ring can be tightly compressed on the water flow passage together by the pressure of the water flow, and the water flow can not pass through the water flow passage, and the automatic closing function is played. The utility model has the advantages of simple structure, easy fabrication, and convenient operation.
Description
The utility model belongs to a kind of running water valve, and specifically a kind of being installed between water pipe and the water tap forgotten throttle down when cutting off the water, and can close the anti-Self-closed water valve of metalling run out in water route when coming water once more automatically.
The employed running water valve of public building and general family is old-fashioned structure at present, it is made of valve body, rotatable handle and spool, spool is housed below rotatable handle, utilizes the rubber sealing gasket below the spool to make line seal decide opening and closing of water route.Its advantage is simple in structure, and is easy to manufacture, easy to use; Its shortcoming is not have self-closing function, if forget when cutting off the water and close, causes gravity flow when coming water once more, the waste water source, simultaneously to resident family and downstairs resident family make troubles, cause unnecessary economic loss.
The purpose of this utility model provides a kind of anti-Self-closed water valve of metalling run out that is installed between water pipe and the water tap, when cutting off the water, the valve cock stem of this Self-closed water valve and seal ring and valve cock stem boss are fallen on the valve body under action of gravity naturally, flow channel is stopped up, when coming water once more, fluid pressure is pressed on valve cock stem on the passway of valve body liquid with seal ring, and liquid can not be passed through, and plays self-closing effect.
For realizing the purpose of invention, the utility model is realized by following scheme.This Self-closed water valve is made of valve body, seal ring, spool, valve cock stem and valve cock stem handle, be characterized in that spool is connected with valve body by the spiral shell button, valve cock stem is connected with the valve cock stem handle, O-ring seal be contained in the valve cock stem boss above, seal ring is contained in the spool groove and seals with valve cock stem, seal ring is fastened on the valve cock stem, and when carrying on the valve cock stem, seal ring is stressed to deform.
The operating principle of this Self-closed water valve is, when the valve cock stem handle is upwards mentioned by valve cock stem drive seal ring and valve cock stem boss, water or liquid pass through naturally along Fig. 1 arrow direction indication, this moment, valve cock stem and seal rubber pad and the effect of valve cock stem boss liquid body pressure difference were compressed by jack-up and spool, can not fall; When no liquid is passed through, valve cock stem and seal ring and valve cock stem boss are fallen on the valve body under the effect of gravity naturally, fluid passage is stopped up, when coming water once more, fluid pressure is pressed on valve cock stem and seal ring on the fluid passage mouth of valve body together, liquid can not be passed through, fluid pressure tightly is pressed in seal ring on the valve cock stem simultaneously, liquid that can not is flowed out along spool, when water is passed through again, the valve cock stem handle is mentioned together with seal ring and valve cock stem boss by valve cock stem, water is passed through along the arrow indicated direction once more.
This self closing stop valve has self-closing function, the valve cock stem of this Self-closed water valve and seal ring and valve cock stem boss are fallen on the valve body under action of gravity naturally when cutting off the water, flow channel is blocked, when coming water once more, fluid pressure is pressed on valve cock stem on the passway of liquid with seal ring and valve cock stem boss, make water not avoid waste using water wisely by playing self-closing effect.Characteristics such as this valve has simple in structure, and is easy to manufacture, easy to use.
Structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is this anti-Self-closed water valve master sectional view of metalling run out;
Fig. 2 is this anti-Self-closed water valve side view of metalling run out.
This Self-closed water valve comprises valve body 1, seal ring 2, spool 3, valve cock stem handle 4, valve cock stem 5 and water cavity 6, wherein spool 3 is connected with valve body 1 by the spiral shell button, valve cock stem 5 is connected with valve cock stem handle 4 by the spiral shell button, there is valve cock stem boss 7 valve cock stem 5 lower ends, seal ring be contained in valve cock stem boss 7 above, seal ring 2 is contained in spool 3 grooves and seals with valve cock stem 5, between valve cock stem 5 and seal ring 2 auxiliary reset spring 9 is housed.Water cavity 6 is arranged in the valve body 1.The valve body 1 of this Self-closed water valve, spool 3, valve cock stem handle 4, valve cock stem 5 available metal material, also available hard non-toxic plastic mould injection forming.
