The two-way stop valve comprises an inner cavity and an outer cavity, wherein the inner cavity and the outer cavity are partitioned by a middle partition board and are then formed, a long screw rod sequentially passes through a valve cover and an air guide pipe on the middle partition board, the long screw rod is in threaded matching with the valve cover, and the long screw rod is provided with an outer plug which is opposite to the top port of the air guide pipe and an inner plug which is opposite to the bottom port of the air guide pipe. According to the invention, when the long screw rod rotates, the inner plug and the outer plug are suitable to oppositely and reversely shift; when the outer plug seals and presses the top port of the air guide pipe, the inner plug is suitable to axially shift along the long screw rod to seal and press the bottom port of the air guide pipe, and then, a valve is closed; the long screw rod is reversely rotate so that the valve is opened; and after the valve body is closed, even if one of the plugs has low sealability due to wear or impurities, the other plug can still close the valve body, in this way, the safety of a high-pressure liquid storage tank is ensured.
Description
Technical field
The present invention relates to a kind of two-way shut-off valve and assembly method thereof, specifically is the valve body that is applied on the high pressure liquid containers such as liquid chlorine jar, liquid gas.
Background technique
Existing high pressure gas holder is used valve, and it often adopts single chock plug, and working life is shorter.Often there is impurity in the high pressure liquid containers such as liquid chlorine jar, liquid gas, is prone to make valve body situation such as leakage to occur, and then causes major hidden danger to social safety.
How to provide a kind of working life overlength, maintenance cost is cheap and be suitable for avoiding the high pressure gas holder of gas leakage to use valve, is the technical barrier of related domain.
Summary of the invention
The technical problem that the present invention will solve provides a kind of simple in structure, overlong service life, the valve body opening and closing speed is very fast, maintenance cost is cheap and be suitable for avoiding the two-way shut-off valve and the assembly method thereof of gas leakage.
For solving the problems of the technologies described above, two-way shut-off valve provided by the invention comprises: valve pocket; This valve pocket comprises the inside and outside chamber that is divided into by intermediate clapboard; Intermediate clapboard is provided with the air pipe that is communicated with said inside and outside chamber, and the bottom of inner chamber is provided with suction port, is communicated with exhaust joint on the sidewall of exocoel; The upper end of valve pocket is provided with valve gap, and a long bolt passes said valve gap and air pipe successively.
Wherein, long bolt cooperates with valve bonnet seal through a Sealing, and this long bolt cooperates with the screw top of said valve gap.The top of long bolt is provided with handwheel.
Be fixed with the outer chock plug that the top port with said air pipe is oppositely arranged on the long bolt in said exocoel; Screw-thread fit has the interior chock plug that the bottom port with said air pipe is oppositely arranged on the long bolt in said inner chamber; Long bolt with this in the following thread section that cooperates of chock plug opposite with hand of spiral with last thread section said valve gap screw-thread fit this long bolt, and then when rotating long bolt, inside and outside chock plug is suitable in opposite directions or reverse displacement.With respect to the mode of single chock plug, have the characteristics of valve body open and close rapid speed.
Interior chock plug comprises plug head and the sleeve that cooperates with the bottom thread of said long bolt that is fixed on this plug head bottom, the bottom sealing of this sleeve, and the cross section of this sleeve is polygonal;
The bottom of said suction port has an annular fitting recess; Be provided with disk in this annular fitting recess; Be distributed with through hole on the disk, disk central authorities are provided with the irregularly-shaped hole that is movably set on the said sleeve, and the sidewall of valve pocket bottom is provided with the Cock screw that is used to lock said disk;
After Cock screw is locked said disk, the irregularly-shaped hole on the said disk with cooperating of said sleeve be suitable for limiting said in chock plug rotate synchronously with said long bolt.
When rotating said long bolt; And the mating face seal that makes said outer chock plug is when being pressed on the top port of said air pipe; Chock plug is suitable for the said long bolt axial displacement in edge and the mating face seal of said interior chock plug is pressed on the bottom port of said air pipe in said, thereby this two-way shut-off valve is closed; The said long bolt of backward rotation can be opened this two-way shut-off valve.
Further, the fitting surface of said inside and outside chock plug is provided with sealing gasket, and the top of the said air pipe of sealing pad and hard, bottom port directly are sealed and matched during use, the sealing effect when guaranteeing that valve body is closed.
Further, the bottom of said valve pocket is provided with flange, with convenient this two-way shut-off valve is sealed on the high pressure gas holders such as being assemblied in the liquid chlorine jar.
Further, the top of said air pipe, the end face of bottom are the annular to outer lug, are deposited on the top, bottom port of said air pipe the sealing effect when guaranteeing to use with the impurity in the liquid gas in reducing jar.
Further; The plug head of chock plug is provided with the decompress(ion) valve that connects said air pipe and said inner chamber on the sidewall of the air pipe in the said inner chamber or on the sidewall of said sleeve or in said; With at said air pipe during, remain in that liquid Yin Wendu in the air pipe raises and the pressurized gas that generate are suitable for entering said inner chamber by said inside and outside chock plug sealing.In practice, it is responsive to temperature to remain in liquid chlorine in the air pipe etc., very easily gasification and the air pressure in the air pipe is raise rapidly rapidly when temperature rises to certain value.The decompress(ion) valve can enter said inner chamber with the pressurized gas that possibly generate in the air pipe; The high pressure that has prevented possibly to exist in the said air pipe has been guaranteed the reliability and the Security of this two-way shut-off valve to the destruction of the effect that is sealed and matched at said inside and outside chock plug and air pipe two ends.
Particularly, said valve gap has the base plate that is sealed and matched on the valve pocket open-topped, and this base plate is provided with through hole, and said long bolt passes this through hole, and said Sealing is located in this through hole.
Further, said Sealing upper end is provided with the pressure strip that is used to compress the sealing part, and this pressure strip is connected on the base plate of said valve gap through a plurality of adjusting bolts.Because it is Sealing often adopts fillers such as tetrafluoroethylene or graphite to constitute, in use easy to wear and influence sealing effect; Adopt the regular fastening sealing part of pressure strip of regulating bolt control, be suitable for guaranteeing sealing effect.
