Description
Technical field
The invention belongs to a kind of push-pull valve, and in particular to a kind of push-pull valve and its preparation technology.
Background technology
At present, push-pull valve is widely used in pipe-line system or vacuum furnace apparatus in all trades and professions such as chemical industry, machinery, metallurgy
In, mainly play sealing function.To push-pull valve, the even normal operation of integral device is suffered from the sealing effectiveness of push-pull valve in itself
Vital effect.
At present, the primary structure of push-pull valve includes valve body and core assembly, and core assembly includes support frame, valve plate and consolidates
The steel ball on support frame is scheduled on, valve plate has the groove that can accommodate steel ball, the upper end of support frame and cylinders.Close and insert
During plate valve, cylinder promotes push-pull valve motion, while the steel ball being fixed on support frame drives valve plate motion, when valve plate is by treating
Sealing space is run during to valve body bottom, valve plate stop motion, and support frame continues to move, and steel ball is removed from groove, supports
Valve opening plate, makes valve plate sturdy with valve body, realizes that valve plate valve treats the sealing of sealing space.When opening push-pull valve, cylinder pumping band
Dynamic support frame counter motion, support frame drives valve plate counter motion simultaneously by steel ball, but due between steel ball and valve plate
Larger frictional force so that steel ball is difficult to be repositioned in groove again, causes valve plate stuck, and easily causes to close on the outside of valve plate
The destruction of sealing rubber ring, when push-pull valve is again turned on, influences the sealing effectiveness of O-ring seal.
The content of the invention
It is an object of the invention to provide a kind of push-pull valve and its preparation technology.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of push-pull valve, it include valve body, body cap, cylinder, cylinder block, roller, push rod, push rod axle, ejectoc box, roller shaft,
Tip-lever support, bonnet, extension spring, valve body upper end set body cap, and valve body lower end portion sets bonnet, and cylinder passes through cylinder block and valve body
Lid connection, the axle of cylinder is connected after passing through body cap with ejectoc box, and the two side ends of ejectoc box pass through push rod, push rod axle, roller, rolling
The movable component connection tip-lever support of wheel shaft composition, one end connection bonnet of extension spring, other end connection ejectoc box.
A kind of preparation technology of push-pull valve, its be valve body welding be first pass through jig fix after weld, wait cooling
Mould is removed again afterwards, valve body lower end portion sets bonnet, the two side ends of ejectoc box pass through push rod, push rod axle, roller, roller shaft group
Into movable component connect tip-lever support, ejectoc box is connected with the axle of cylinder, the ejectoc box that will be assembled is installed in valve body, drawing
One end connection bonnet of spring, other end connection ejectoc box, body cap is fixed with valve body, and cylinder block is arranged on body cap, cylinder
On cylinder block.
It is an advantage of the invention that：Simple structure of the invention, by extension spring so that ejectoc box good seal, process is simple, essence
Degree is high.

Lid connection, the axle of cylinder is connected after passing through body cap with ejectoc box, and the two side ends of ejectoc box pass through push rod, push rod axle, roller, rolling
The movable component connection tip-lever support of wheel shaft composition.
A kind of preparation technology of push-pull valve, its be valve body welding be first pass through jig fix after weld, wait cooling
Mould is removed again afterwards, valve body lower end portion sets bonnet, the two side ends of ejectoc box pass through push rod, push rod axle, roller, roller shaft group
Into movable component connect tip-lever support, ejectoc box is connected with the axle of cylinder, the ejectoc box that will be assembled is installed in valve body, drawing
One end connection bonnet of spring, other end connection ejectoc box, body cap is fixed with valve body, and cylinder block is arranged on body cap, cylinder
On cylinder block.
Specific embodiment described herein is only the technology neck belonging to the present invention to the present invention spiritual explanation for example
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from spirit of the invention or surmount scope defined in appended claims.
