The utility model can realize the opening-closing of the valve without external force but only by using the pressure of the high-pressure on the side of a fluid system where the valve is. is not large in the deformation of the hose when the valve is opened and closed, and only needs to increase the quantity of the hoses in the valve to large-flow valves, which is simple in structure and convenient to maintain.
Description
Technical field
The utility model relates to the sebific duct structure and the rubber pipe valve open-shut device structure of a kind of rubber pipe valve, particularly a kind of rubber pipe valve.
Background technique
In the prior art, rubber pipe valve has valve body, and sebific duct is housed in the valve body, be the runner of fluid in valve in the pipe of sebific duct, valve body is interior, sebific duct has flashboard outward, and valve rod is arranged on the valve body, flashboard links to each other with valve rod, be rotary with handwheel on the valve rod, during throttle down, rotation hand wheel, valve rod moves downward, promote flashboard, flatten sebific duct, sebific duct is ended.This valve needs external force that sebific duct is flattened when each switch, makes sebific duct produce very big distortion, closes for a long time or multiple switching is easy to cause the sebific duct local damage, influences the working life of rubber pipe valve.In addition, this valve is to use the external force switch, very effort.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, when proposing a kind of switch valve the distortion of sebific duct little, with fluid pressure switch without the fluid pressure switch valve external force switch, long service life.
Invention scheme of the present utility model is that flat is made in the stage casing of the sebific duct in the rubber pipe valve, forms Seal cage between the inwall in the outer wall in the flat stage casing of sebific duct and valve body stage casing.During use, fluid can the spreading flat hose, flows through from sebific duct, when adding the pressure of valve inlet end fluid in the Seal cage, the stage casing of sebific duct can be pressed into the flat of nature by spreading by pressure, and further sebific duct is compressed so that end, during unlatching, remove the pressure of the valve inlet end fluid that is added in the Seal cage, fluid again can the spreading flat hose, from sebific duct, flow through,, realize the switch of valve promptly by the pressure in the control Seal cage.
For realizing the foregoing invention scheme, the fluid pressure switch valve is a kind of rubber pipe valve, the fluid pressure switch valve has valve body, valve body has into, outlet, sebific duct is arranged in the valve body, sebific duct has into, outlet, advancing of sebific duct, the outlet valve body in valve body is respectively advanced, export a side, the stage casing of the body of sebific duct is the flat section, in the valve body, advancing of valve interior wall and sebific duct, have respectively between the outlet, the exit seal valve seat, in the valve body, advancing of sebific duct, form between the valve interior wall of exit seal valve base chamber and the sebific duct outer wall Seal cage is arranged, the exit seal valve seat has the taper pipe that inserts in the sebific duct outlet, on the wedge surface of taper pipe osculum is arranged, communicate between the inlet of above-mentioned Seal cage and fluid pressure switch valve, communicate with control valve between the outlet of Seal cage and fluid pressure switch valve.
During use, the fluid pressure switch valve is installed in the fluid-transporting tubing.During valve opening, valve between the outlet of Seal cage and fluid pressure switch valve is in the state that the outlet that makes above-mentioned Seal cage and valve body is conducting, fluid in the sebific duct is the flat section spreading in sebific duct stage casing, flow through in the sebific duct of fluid in the valve body, will pass the osculum on the sphenoid surface of taper pipe of outlet valve seat when flowing through in the sebific duct of fluid in valve body.During valve closing, allow the valve between the outlet of Seal cage and fluid pressure switch valve be in closed condition, the inlet of valve body and above-mentioned Seal cage are the states of conducting, the pressure of inlet side high-pressure liquid can affact the outer wall of sebific duct, pressure can be pressed into the stage casing of sebific duct the flat of nature, the sebific duct inwall is close on the sphenoid surface of the taper pipe that exports valve seat, and the osculum on the sphenoid surface is sealed, and the fluid that flows in the sebific duct is ended.
For the bigger valve of flow, can in valve body, arrange a plurality of sebific ducts.
The utility model only just can be realized the switch of valve without external force with the pressure of valve place fluid system inlet side fluid, during valve switch, the sebific duct distortion is little, and valve is longer working life.Simple in structure, easy to maintenance.
