Abstract
The invention relates to a guiding piston stopping valve, comprising valve body, piston, micro control valve, valve cover, spring and valve clack. Structure adjusted in the guiding piston valve, flow direction changed, jam of guiding hole prevented, and pressure waste decreased are accomplished so as to save energy and prolong the service life.
Description
Technical field: the present invention relates to a kind of valve, particularly a kind of low power consumption energy-saving valve.
Background technique: consult reference materials and market survey, the present pilot piston type stop valve that uses, flow of liquid all is high in and low out when valve seat, liquid produces siphonage to flap, and the distance between flap and the valve seat is dwindled, and has hindered the circulation of liquid, cause the pressure drop of liquid too big, pilot hole easily stops up, and working life is short, does not reach purpose energy-conservation and that increase working life.
Summary of the invention
In order to overcome the deficiency that existing guided piston type valve energy loss is too big and lack working life, the invention provides a kind of pilot piston type stop valve, it is to change the flow direction of existing pilot piston type stop valve and stop guide's micropore to stop up, and satisfies the purpose that the present invention is energy-conservation and increase working life.
Technological scheme of the present invention is to realize like this
A kind of pilot piston type stop valve, it is by valve body, piston, micro-control valve, valve gap, spring, flap is formed, center upper portion at valve body has circular hole, and piston jacket is installed in the circular hole, and piston is installed in the piston jacket, the piston lower end is connected with flap, flap lower end surface and valve seat contact seal, the flap center upper portion has aperture, and the middle and lower part has macropore, aperture is connected with macropore, the top of valve body is equipped with valve gap, between valve gap and the piston spring is installed, and the valve gap upper-end surface is equipped with micro-control valve, the valve body left end is flanged (FLGD) admission chamber, by valve gap, piston jacket, piston surround the load chamber, the valve body right-hand member is flanged (FLGD) sap cavity that goes out, admission chamber communicates with the load chamber by central aperture in the flap, and the load chamber is by valve gap, micro-control valve with go out sap cavity and communicate.
The invention has the beneficial effects as follows that guided piston type is gone on valve and adjusted structure, change flow direction, stoped the obstruction of pilot hole, reduced the pressure loss, thereby reach purpose energy-conservation and that increase working life.
