Abstract
The utility model discloses a kind of high-pressure water tap relying on water pressure itself to seal, comprise valve body, unidirectional valve gap, push rod, cam and handle, valve body is provided with water intake, water outlet and handle mount inlet, valve pocket is provided with between water intake and handle mount inlet, in valve pocket, push rod is installed, cam contact in push rod one end and handle mount inlet, connecting handle above cam, it is characterized in that: the described push rod the other end contacts with the unidirectional valve gap in water intake, the internal diameter of valve pocket is less than the internal diameter of water intake, water intake interior edge face and unidirectional valve gap interior edge face fit tightly, described water outlet and valve pocket through.The utility model structure is simple, and entirety by any pottery, rubber seal rings for seal, does not utilize water pressure itself hermetically closing, high temperature resistant, is not afraid of and freezes, resistance to 200 MPa high pressure, long service life.
Description
Technical field
the utility model relates to water pipe and to dam valve field, is specifically related to a kind of high-pressure water tap relying on water pressure itself to seal.
Background technique
Current water pipe dams the stopped flow technique that the many employings of valve are blocked up against the current, intercepts that sealed member is equipped with pottery substantially, rubber seal is sealed in water tap, and the bearing pressure of water tap is limited, and sealing ring material is easy to damage, generation is leaked, and water tap is not high for working life, and causes water waste.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of high-pressure water tap relying on water pressure itself to seal, and whole structure for water tap is simple, not by any pottery, rubber seal rings for seal, utilize water pressure itself hermetically closing, high temperature resistant, be not afraid of and freeze, resistance to 200 MPa high pressure, long service life.
The utility model is achieved through the following technical solutions:
A kind of high-pressure water tap relying on water pressure itself to seal, comprise valve body, unidirectional valve gap, push rod, cam and handle, valve body is provided with water intake, water outlet and handle mount inlet, valve pocket is provided with between water intake and handle mount inlet, in valve pocket, push rod is installed, cam contact in push rod one end and handle mount inlet, connecting handle above cam, it is characterized in that: the described push rod the other end contacts with the unidirectional valve gap in water intake, the internal diameter of valve pocket is less than the internal diameter of water intake, water intake interior edge face and unidirectional valve gap interior edge face fit tightly, described water outlet and valve pocket through.
The further improvement project of the utility model is, the surface finishment of described water intake interior edge face and unidirectional valve gap interior edge face is within Ra0.8.The pressure itself of current, can ensure best sealing effect.
The utility model further improvement project is, described unidirectional valve gap adopts titanium alloy material.Unidirectional valve gap adopts this material to produce Never-rusty, and longer service life is of a specified duration.
The utility model further improvement project is, described unidirectional valve gap interior edge face is provided with groove, and push rod is inserted in groove.
The utility model further improvement project is, is installed with pagoda spring in the water intake outside described unidirectional valve gap.Both can push down valve gap, and prevent valve gap from coming off, and also can promote valve gap resilience when closed tap and be fitted on import water interior edge face, realize fitting tightly.
The utility model compared with prior art, has following obvious advantage:
The utility model turns clockwise 90 degree, handle, and cam promotes push rod, and push rod promotes unidirectional valve gap and leaves water intake interior edge face, and through water intake and valve pocket, water outlet, realize open water tap; Rotary handle 90 degree, push rod is retracted, and unidirectional valve gap falls after rise under the pressure itself of current, and unidirectional valve gap interior edge face and water intake interior edge face are fitted, and block current, realize self-enclosed, and namely water tap is closed.The utility model structure is simple, and entirety by any pottery, rubber seal rings for seal, does not utilize water pressure itself hermetically closing, high temperature resistant, is not afraid of and freezes, resistance to 200 MPa high pressure, long service life.
Accompanying drawing explanation
Fig. 1 is the utility model structure sectional view.
