Abstract
The utility model discloses a kind of high pressure cushion stop valve that can control fluids within pipes flowing, be mainly used in each technological process in oil field or relevant device, be intended to solve current high-pressure stop valve in use easily block, seal cone easily bad, the pressure cap easy to leak of thorn, the technical barriers such as screw mandrel frangibility in duct.The utility model is formed by connecting by screw-thread fit by each cylindrical body, and it includes valve body, joint, push rod, valve block, seal ring, sealing gasket.What adopt is the straight control mode directly gone out, and sealing means is soft or hard double-sealing, and sealing pair is soft material and cemented carbide.
Description
Technical field
The utility model relates to a kind of gate, refers more particularly to the high pressure cushion stop valve that a kind of sealing pair is soft material and cemented carbide.
Background technique
Current known high-pressure stop valve is that screw mandrel, pressure cap, Glan, stuffing box packing and handwheel are formed by valve body, sealing cone.Fluid is low in and high out in valve body, acts on sealing cone, coordinate play switching function with valve body central seal hole by rotation hand wheel, screw mandrel.But this stop valve in use, fluid duct easily blocks, sealing cone and closed hole is perishable and sting bad, therefore valve seal poor performance, and life cycle is short, but also there is pressure cap place easy to leak, the shortcoming such as screw mandrel frangibility during switch.
Summary of the invention
The purpose of this utility model is to provide a kind of structure simple, good seal performance, the high pressure cushion shutoff valve that life cycle is long, thus overcomes existing high-pressure stop valve poor sealing performance and fluid passage easily blocks, screw mandrel frangibility and the shortcoming such as life cycle is short.
The technical solution of the utility model is:
This high pressure cushion stop valve, employing be the straight opening and closing mode directly gone out, sealing means is soft or hard double-sealing, and sealing pair is soft Nylon and cemented carbide.It mainly includes valve body, joint, push rod, valve block, seal ring, sealing gasket.Joint is connected with valve body one end; Push rod one end is in valve body, and the other end is in outside valve body, and is connected with screw thread; Valve block is in valve body, is positioned at the top of push rod; Sealing gasket is in valve body, between valve block and joint; Seal ring is in valve seal groove.
Described valve body is cylinder hollow structure, and wherein one end and intermediate portion are respectively provided with one section of internal thread, and the other end inside is provided with seal groove.
Described joint is provided with central duct and one section of externally threaded cylindrical body, and be connected with valve end screw thread, end is provided with annular seal groove, for installing sealing gasket.
Described push rod is provided with central duct, and wherein one end is provided with boss, is provided with groove in boss, and groove is connected with center hole, and side, boss side is provided with duct and is connected with central duct is vertical.Be provided with outside thread in the middle part of push rod, the other end is provided with one section of internal thread.
Described valve block, one end is cone, and the middle and the other end is cylindrical body, is in push rod boss groove.
Described sealing gasket is annular gasket, is between joint and valve block.
Described seal ring is zero type circle, is in valve seal groove.
During use, lower connector being connected with each technological process, the utility model can being opened or closed by rotating push rod.
The beneficial effects of the utility model are: manufacturing process is simple, and cost is low; Straight directly the going out of fluid passage employing, not easily blocks, and cleaning impurity is convenient; Sealing means is soft or hard double-sealing, and good seal performance, life cycle is long.
