Description
Technical field
The present invention relates to a kind of gate valve, more precisely, being a kind of Pneumatic gate valve.
Background technology
The opening and closing element of gate valve is flashboard, and the direction of motion and flow direction of flashboard are perpendicular, and gate valve can only make standard-sized sheet and complete
Close, cannot make adjustments and throttle.Flashboard has two sealing surfaces, and two sealing surfaces of most common pattern slide valve form wedge
Shape, key groove are different with valve parameter, are usually 50, are 2 ° of 52' when medium temperature is not high.The flashboard of Wedge Gate Valves can
To be integrally formed, it is called rigid flashboard;Can also make can produce the flashboard of micro-deformation, to improve its craftsmanship,
The deviation that sealing surface angle produces in process is made up, this flashboard is called flexible disc.Pneumatic gate valve is by pneumatic
The gate valve that actuator control valves bar rotates, the Pneumatic gate valve being commonly used often go out when pneumatic actuator drives
Existing cylinder presses through high situation, this have impact on the stable operation of gate valve.
The content of the invention
The present invention mainly solves the technical problem present in the prior art, so as to provide a kind of Pneumatic gate valve.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals:
A kind of Pneumatic gate valve, comprising a valve body, is rotationally equipped with a valve rod on valve body, valve body is equipped with a stent, on stent
Equipped with a pneumatic actuator, pneumatic actuator driving stem rotates, and pneumatic actuator is equipped with a fixinig plate, and fixinig plate is equipped with
One fixed slot, is also connected with a diversion pipe on pneumatic actuator, and the end of diversion pipe is equipped with a voltage stabilizing cylinder, on pneumatic actuator
A pair of of poppet valve is additionally provided with, poppet valve is connected with voltage stabilizing cylinder.
As preferred embodiments of the present invention, the stent is connected between valve body for screw rod.
As preferred embodiments of the present invention, the casing wall of the voltage stabilizing cylinder is double-decker.
The main body of the Pneumatic gate valve of the present invention includes the pneumatic actuator that gate valve body and a driving gate valve rotate, pneumatically
The rotation that a fixinig plate is used to stablize pneumatic actuator is provided with actuator, the cylinder connected on pneumatic actuator is when execution
Device internal pressure it is excessive when can absorb part internal pressure, internal pressure then discharges gas higher than the tolerance range of voltage stabilizing cylinder by relief valve
Body, so as to ensure the even running of Pneumatic gate valve.
Brief description of the drawings

42 connect with voltage stabilizing cylinder 41.
Connected as to further improvement of the present invention, the stent 20 between valve body 10 for screw rod.
It is double-decker as the casing wall to further improvement of the present invention, the voltage stabilizing cylinder 41.
The main body of the Pneumatic gate valve of the invention includes the pneumatic actuator that gate valve body and a driving gate valve rotate, pneumatically
The rotation that a fixinig plate is used to stablize pneumatic actuator is provided with actuator, the cylinder connected on pneumatic actuator is when execution
Device internal pressure it is excessive when can absorb part internal pressure, internal pressure then discharges gas higher than the tolerance range of voltage stabilizing cylinder by relief valve
Body, so as to ensure the even running of Pneumatic gate valve.
Only illustrate the mentality of designing of the present invention in one embodiment above, in the case where system allows, the present invention can
To expand to while external more function modules, so as to extend its function to greatest extent.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, it is of the invention
Protection domain should be determined by the scope of protection defined in the claims.
