Description
Technical field
The utility model relates to ball valve, particularly relates in integrated type duplex and fills fixing ball valve.
Background technique
Existing duplex fixing ball valve mostly is three-body type through Bolt Connection ball valve, and spheroid loads valve body from the side, this structure the is many leak point at bolt place, and can not On line inspection and maintenance after pipeline pressure release.Traditional duplex fixing ball valve also exists after pipeline pressure release can not the problem of On line inspection and maintenance.
Model utility content
The purpose of this utility model is to provide in integrated type duplex and fills fixing ball valve, and solving that traditional duplex fixing ball valve in prior art also exists after pipeline pressure release can not the problem of On line inspection and maintenance.
The technological scheme that the utility model adopts is: integrated type duplex fills fixing ball valve, comprise valve body, lower shaft, adjustment circle, valve seat, spheroid, valve rod, valve gap and actuator, valve body solid forging processes, valve body and valve gap pass through Stud connection, lower shaft is fixed on inside valve body, valve rod is fixed by upper cover, spheroid upper end rectangle groove connects with valve rod, spheroid lower end axis hole connects with lower shaft, valve rod upper end embeds the keyway of actuator, actuator and valve gap upper flanges pass through Bolt Connection, two valve seats and two spheroids are provided with in valve body chamber, two valve seats form two sealing pairs, valve body in lumen arranges the interface of a pressure medium of releasing, outlet valve is settled in interface outer end.
The utility model compared with prior art tool has the following advantages: valve body solid forging forms, two valve seats, two spheroids are provided with in valve body chamber, two valve seats form two sealing pairs, valve body in lumen arranges the interface of a pressure medium of releasing, outlet valve is settled in interface outer end, and stack valve seat ensures that medium is without any internal leakage; Ball valve fluid resistance is minimum, and valve isolates the pressure of each entrance, and the function of cavity between emptying valve seat, reach dual fail-safe Leakage prevention, easy to operate, increase the service life, actuator drives spheroid to rotate by valve rod, realizes opening or closing of ball valve, realizes On line inspection and maintenance.
Accompanying drawing explanation
