Description
Technical field
The present invention relates to water conservancy valve technology field, a kind of water conservancy stop valve with pressure protective device is particularly belonged to.
Background technology
Valve is the control unit in fluid delivery system, with cut-off, regulation, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the function such as overflow pressure relief.
Stop valve, is also pipe valve, is a kind of most popular valve, and why very popular it is, is due to being opened and closed
Frictional force is small between sealing surface in journey, relatively durable, and Lift is less, easy to manufacture, easy to maintenance, low in being applicable not only to
Pressure, and suitable for high pressure；Its closure principle is, by valve stem pressure, makes valve core sealed cover and valve seat permeable hole sealing surface
It is brought into close contact, prevents flow of media；Stop valve is only permitted medium one-way flow, directional during installation.Its structure length is more than
Gate valve, while fluid resistance is big, during longtime running, sealing reliability is not strong.
The content of the invention
It is an object of the invention to provide a kind of water conservancy stop valve with pressure protective device, prior art is overcome
Deficiency, sets pressure-bearing protection hole on valve element, and elastic motion stops are set on protection hole, when the hydraulic pressure that stop valve is carried is excessive, surpasses
When going out its bearing capacity, hydraulic pressure is expressed to elastic activity beyond the Great Wall through protection hole, and elastic motion stops are opened by hydraulic pressure, realizes
Weep circulates, and so as to protect cut-off valve body, the scope of application is wide.
To solve the above problems, the technical solution used in the present invention is as follows：
A kind of water conservancy stop valve with pressure protective device, including valve body and valve element, are provided with valve seat in described valve body, described
Valve seat in the middle of be provided with taper permeable hole, be combined with control-rod on described valve element, described valve body top is provided with erecting bed, institute
Seal cover board is provided with by sealing ring and bolt on the erecting bed stated, adapter sleeve is provided with the middle of described seal cover board, it is described
Control-rod bottom and valve element welding, top be provided with rotating handles, centre be connected with adapter sleeve by helicitic texture, described valve
Core is provided with protection hole, and described protection hole runs through whole valve element, sliding sleeve and cunning are provided with by connecting plate on described control-rod
Bar, described slide bar bottom is provided with the motion stops coordinated with protection hole, is located on described slide bar and is set between sliding sleeve and motion stops
There is spring structure.
Further, described adapter sleeve lower section is provided with sealing shroud, and caulking gum is provided with described sealing shroud.
Further, described valve element is for pyramidal structure and the outside conical surface is provided with caulking gum layer.
Further, motion stops top is located on described slide bar adjusting nut is connected with by helicitic texture.
Further, described motion stops are pyramidal structure and are made up of rubber.
Compared with prior art, implementation result of the invention is as follows for the present invention：
A kind of water conservancy stop valve with pressure protective device of the present invention, sets pressure-bearing protection hole on valve element, protects hole
Upper to set elastic motion stops, when the hydraulic pressure that stop valve is carried is excessive, when beyond its bearing capacity, hydraulic pressure is squeezed through protection hole
It is pressed onto elastic activity beyond the Great Wall, elastic motion stops are opened by hydraulic pressure, realizes that weep circulates, so as to protect cut-off valve body, fits
Use wide scope.
