Abstract

An Automatic closing device for turn-off of tap water comprises a cylinder, a floater and an ejector. The automatic closing device for turn-off of tap water is characterized that a water pipe (2) is arranged in the cylinder (1); a taper hole (3) is reserved at the center of the water pipe, and screw threads (4) are reserved at both ends of the water pipe. A floater (5) is arranged in the taper hole, a sealing ring (6) is arranged at the center of the lower portion of the cylinder, and the ejector (7) is arranged in the sealing ring. The automatic closing device for turn-off of tap water overcomes defects of existing tap water turn-off facilities and has the advantages of simple process, low cost, convenience in use, remarkable water saving effect and the like. .

Description

The stopping running water self-closing device

Technical field

The utility model relates to the water-saving device field, a kind ofly more precisely utilizes float buoyancy and deadweight principle and the device of the water-cut off self-closure that designs.

Background technique

China is one of country of World Water scarcity of resources, and using water wisely is rooted in the hearts of the people, and therefore, product and the patent repeatedly utilized of various water savings and water are arisen at the historic moment, and ignore part but still have by people: some cities and towns changes regularly supply into because water resources lacks.As everyone knows in the prior art, people's daily life water or industrial water. mainly come the flow of switch and adjusting water by water tap, because this water tap manual operation, in case cut off the water suddenly. the water tap people that open forget again closing conveniently. when again coming water, because water tap can not autoshutdown, if be unmanned in the family, and cause tap water to be wasted in vain, even also can bring domestic articles to suffer the loss of water logging and cause great neighbourhood's dispute.In recent years, although there is successively the patent such as tap water cut-off safety valve to occur, it has solved tap water after cutting off the water, and comes water again and the hydraulic overflow problem that causes, and these tap water cut-off devices are are all laid aside and neglected because of needs electricity consumption or cost of production height.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of technique is simple, cost of production is low, easy to use, water-saving result installs significantly.

The purpose of this utility model adopts following technical measures to realize: a kind of stopping running water self-closing device, formed by cylindrical shell, float, push rod, it is characterized in that: water pipe is housed in cylindrical shell, there is a cone shape hole at the water pipe middle part, the water pipe two ends are shaped with screw thread, are convenient to be serially connected between intake pipe and water tap, the valve.Cone shape hole is built-in with float, and described float is taper, and its tapering and cone shape hole match, and available plastics or metal are made.There is a seal ring in center portion, cylindrical shell below, and push rod is housed in the seal ring, and there is a catch push rod upper end.Working principle and using method: when water tap first during water, the tap of fetching boiling water pushes away a lower push rod, water in the cylindrical shell floats float, guarantees normal water, during closed tap, because contain water in the cylindrical shell, float is in the come-up state, does not affect next water, when cutting off the water, dehydration in the cylindrical shell, float relies on self gravitation to fall, and blocks cone shape hole, reaches self-closing purpose.

The stopping running water self-closing device that the utility model provides, its remarkable result: technique is simple, cost of production is low, easy to use, water-saving result is remarkable.

Description of drawings

Accompanying drawing is structural representation of the present utility model.

Below in conjunction with accompanying drawing the utility model is further elaborated.

Embodiment
