Just, maintenance cost is low.
Technical solution adopted in the utility model is as follows：
A kind of gas control threeway angle valve, it is characterised in that：Including control unit, operating member and valve body；The control unit includes
Cylinder barrel, sealing valve chamber, the first inlet end, the second inlet end, piston；Valve chamber is divided into two independent gas chambers up and down by the piston,
First inlet end, the second inlet end are located on the valve chamber of piston upper and lower ends, the first inlet end, the second inlet end respectively with
Air source connects；Operating member is the spool part of the valve rod and its lower end that are connected with piston, and installing seal spool pad in spool is
Rubber or PTFE materials form sealing between the seal spool pad and valve body；Cavity portion among valve body is oval spherical
（See Fig. 4 Fig. 5）, and having four end interfaces, upper end interface is connected with upper end control unit, and left and right is connected with terminal tract respectively, lower end
Mouth is connected with valve seat.
Further, there is connection that the two is connected by screw thread among control unit and valve body, have among the connection certain
The seal assembly of quantity, valve rod move up and down inside it, it is ensured that the leakproofness above and below valve rod, and the connection upper end
Side is connected with the outside world equipped with through-hole, can further increase the safety of valve stem seal, and the sealing convenient for monitoring valve rod can
By property.
Further, valve seat is connected with valve body with screw thread in valve body bottom end, the valve seat upper end and seal spool pulvilliform
At sealing, and lower end is connected with pipeline.
Advantageous effect
The present invention carries out the control to valve using gas control mode, and unlatching is rapid, adjusts accurate, safe operation, Er Qieqi
Cylinder top such as can closely switch at other attachmentes with adjunction, realize the remote control of valve；Intermediate cavity portion of the invention is ellipse
It is spherical（See Fig. 3 Fig. 4）, size meets casting standard with wall thickness etc. everywhere, and the structure can greatly reduce flow resistance, reduces
The pressure loss can about make piping flow improve 30%；Between valve body and seal spool pad of the present invention and valve seat and seal spool pad
Between sealing be linear sealing form, sealing effect is more reliable, and adapts to more complex working conditions；Lower value seat of the present invention
The internal diameter size at place is identical as spool, so medium is to right end（Or left end）When conveying, and to when conveying at lower value seat, mouth
Diameter is duplicate, so several outlets can keep good flow consistency；Since invention itself can be realized
The multiple functions such as commutation, shunting, the interflow conveying of medium, it is possible to greatly improve production efficiency, while can both save
Space can save the energy again.

Specific implementation mode
The utility model is described in further details with reference to specific embodiment and attached drawing.
A kind of gas control threeway angle valve, including control unit, operating member and valve body；The control unit includes cylinder barrel, sealing valve
Chamber, the first inlet end, the second inlet end, piston；The piston by valve chamber be divided into up and down two independent gas chambers, the first inlet end,
Second inlet end is located on the valve chamber of piston upper and lower ends, and the first inlet end, the second inlet end are connect with air source respectively；It is dynamic
Make the spool part that portion is the valve rod and its lower end that are connected with piston, installation seal spool pad is rubber or PTFE in spool
Material forms sealing between the seal spool pad and valve body；Cavity portion among valve body is oval spherical（See Fig. 4 Fig. 5）,
And having four end interfaces, upper end interface is connected with upper end control unit, and left and right is connected with terminal tract respectively, lower port and valve seat phase
Even.
One of which application state of the present invention is：If being passed through air source in the second inlet end, forces piston moves down, band ovable valve stem
