Description
Technical field
The utility model relates to valve field more particularly to a kind of ball valve sealing structures in pneumatic ball valve.
Background technique
Ball valve is a kind of valve that opening and closing element (sphere) is driven by valve rod, and rotated around ball valve axis.Ball valve is
Guarantee that the key device of pneumatic system reliability will affect the conveying stability and pressure of power if its sealing performance is bad
The real-time etc. adjusted with flow not only influences the reliability and peace of system so that system pressure and Traffic Anomaly be caused to fluctuate
Quan Xing, and the evaluation of engine performance and parameter is influenced, it is serious to will lead to engine damage and casualties.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, it provides a kind of in pneumatic ball valve
Ball valve sealing structure, this structure ensures that sealing and leakage sealing in the valve body of pneumatic ball valve, avoid pressure leakage or corrosion from becoming
Shape provides reliable and stable support to pneumatic system operation.
It is a kind of close for the ball valve in pneumatic ball valve that in order to achieve the above purposes, the technical solution adopted by the utility model is:
Seal structure includes left valve barrel, right valve barrel, adjusting pad, valve seat, spring, O-ring seal, spool；The left valve barrel is ball valve
Ball-and-socket type hollow valve body structure, the left valve barrel end face are connected with right valve barrel, and setting on the inside of left valve barrel end face by flange bolt
There is one of annular groove；The right valve barrel is the half ball-and-socket type hollow valve body structure for cooperating left valve barrel end face, left valve barrel and right valve barrel it
Between form spherical hollow space, which is sleeved in left valve barrel, and right valve barrel end face on the inside of be provided with one end annular groove；
It is provided with adjusting pad in the left valve barrel annular groove, which fits with left valve barrel, right valve barrel respectively；The right valve barrel
Circular valve seat is provided in annular groove, which is the conical surface to ball valve center one side chamfered, and is provided on the valve seat conical surface
Horizontal groove；The setting of right valve barrel annular groove end face valve seat joint place is fluted, and welded connecting is equipped in the groove in right valve
Spring between body and valve seat；O-ring seal is installed in the groove of the valve seat；Globe valve is placed on the valve seat conical surface
Core.
Preferably, the right valve barrel side is provided with left valve barrel joint place, valve seat side and right valve barrel joint place
