Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of ball valve.
Background technique
At present, General low temperature ball valve generally adopts one-way sealing structure, and the sidewall of the corresponding valve body upstream extremity of spheroid is provided with a relief hole, and when spheroid is closed, valve pocket communicates with upstream high medium all the time, avoids medium low temperature gasification to cause contingency.Valve stem part adopts long-neck vibrational power flow, makes stuffing box packing away from spheroid one end, to guarantee the sealing of valve valve rod in long-term switching process.The defect of this General low temperature valve is: owing to working under low-temperature condition for a long time, its valve body primary seal only depends on the sealing of prefastening spiral wound gasket, working life is shorter, and valve stem top stuffing box packing is in high and low temperature alternative state for a long time, and same working life is shorter.
Model utility content
In view of this, the application provides a kind of ball valve, and this ball-valve structure is compact, preparation process is simple, easy to install, and sealing is strong.
For solving above technical problem, the technological scheme that the utility model provides is a kind of ball valve, comprises valve seat, valve body, valve rod, handle, spheroid, and described valve body is also provided with position limit pin, and described position limit pin is arranged on the front end of described valve rod; Recess hole is provided with in described handle rear end portion;
Described valve body is provided with valve seat back-up ring, described valve rod connects described spheroid through described valve body; Described valve rod upper end arranges screw and spring washer is fixedly connected with described handle.
Further, described valve seat back-up ring is also provided with the O RunddichtringO for sealing described valve body and described valve seat.
Further, the packing ring for sealing also is provided with between described stem lower portion and described valve body.
Further, described valve rod is provided with outstanding block through valve body intermediate portion, is provided with back-up ring, the 3rd O RunddichtringO in block and between valve rod.
Further, described valve seat is connected with adapter by cap nut.
Further, the packing ring for sealing, adapter back-up ring and the 4th O RunddichtringO is also provided with between described cap nut and described adapter.
Compared with prior art, the beneficial effects of the utility model are:
The utility model ball-valve structure is compact, and the mode adopting back-up ring and class O RunddichtringO to combine seals, and ensure that the sealing reliability of valve, extends the working life of valve.This ball valve preparation process is simple, easy to install, and sealing is strong.
