Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
It please refers to Fig. 1-4, a kind of guide's high pressure clip shut-off valve, including the side pilot valve A1, pilot valve A1 and passes through shaft
It is connected with handwheel, is realized and is opened and closed by the hand wheel rotating of setting, realize the disengaging of highly pressurised liquid；Pilot valve A1 is connected
Main structure outer surface be provided with aperture, promote highly pressurised liquid to enter the upper cavity of pilot valve 10 by aperture, because upper
Lower cavity area is different, and the thrust of epicoele is greater than the top power of lower part, synthesizes downward stress, the handwheel component of corresponding closure rotation
With regard to very little；The side pilot valve A1 is provided with soket head cap screw 2, the main structure that pilot valve A1 is connected spliced by up-down structure and
At and be fixedly connected by soket head cap screw 2 therebetween, superstructure is provided with handwheel, and substructure is provided with pilot valve
10, handwheel realizes the disengaging of highly pressurised liquid, forms composite structure with pilot valve 10 and realizes the small stress of hand handle jointly；Pilot valve
It is provided with O-ring A3 below A1, is provided with retaining ring A4 on the outside of O-ring A3, O-ring A3 is internally provided with spring 5, among spring 5
It is provided with O-ring B6, it is upper among pilot valve A1 that retaining ring B7, retaining ring B7 and O-ring B6 setting are provided on the outside of O-ring B6
Position is provided with O-ring C8 among spring 5, and retaining ring C9, retaining ring C9 and O-ring C8 are provided on the outside of O-ring C8 and is arranged in guide
Side position, pilot valve A1 are internally provided with pilot valve 10 on the lower among valve A1, and pilot valve 10 is internally provided with spring 5, first
10 upper right side of guide valve core and lower left side are connected with connector 11, and 10 outer surface of pilot valve is equipped with valve body 12,10 bottom of pilot valve
Portion is tapered, chimeric to be mounted on inside valve body 12, realizes that pilot valve 10 is fixedly connected with valve body 12, so that highly pressurised liquid enters elder generation
The upper cavity of guide valve core 10, because area causes synthesis Impact direction downward, the power of handwheel is with regard to very little；Connector 11 is arranged in valve body
Inside 12,11 outer periphery of connector has been fitted around O-ring D13, and O-ring D13, which runs through, is connected with pilot valve 10.
Working principle: when this guide high pressure clip shut-off valve works, pilot valve A1 handwheel is in close state, highly pressurised liquid
Into lower end connector 11, pushes pilot valve 10 to arrive 12 top of valve body, come out from upper end connector 11；If necessary to close high pressure liquid
Body, as long as turn handwheel to the right, highly pressurised liquid enters the upper cavity of pilot valve 10 by aperture, because of upper cavity area
Greater than spool lower part area, therefore the thrust of epicoele is greater than the top power of lower part, 10 downlink of pilot valve, close lower end connector 11 into
Liquid.Realize closing function；The power of handwheel is with regard to very little in this way.
In summary: this guide high pressure clip shut-off valve realizes the stress of handwheel very by the pilot control structure of setting
It is small, so that the stress very little of handle rotation steel ball；Also make bigger in pressure hand in the bigger pipeline of steel ball, after jacketed cylinder
The stress very little of rotation steel ball, the card slot of hand handle and steel ball is less likely to be damaged, because great safety problem, the people may be not present
Appurtenance production and life security be protected.
