The valve rod of conventional valves is directly connected to valve plate, and stem bottom vertex is hanging, and the both sides by heading on valve plate are transported down
Dynamic to be bonded flashboard with valve body sealing surface, such structure is higher to Geometrical Tolerance Principle, and be easy to cause sealing surface asymmetric
Abrasion, when valve rod, which heads on flashboard, to be moved down, there are deviations on the center of flashboard and the center theory of valve body, work as valve
When firmly fastening, valve body will make flashboard deviate center, generate a small angle, such both sides sealing surface stress is not
, sealing performance is influenced, seal pressure is excessive, and sealing surface wear is more serious, meanwhile, when valve swings to setting, due to itself
Gravity it is possible that the phenomenon that rotating automatically to two sides, causes valve seal not tight, influence work, Chinese utility model is public
The number of opening is that CN206845953U discloses a kind of valve, including valve body, valve rod and valve plate, and the valve plate end, which is dug, has circle recessed
Slot is provided with anti-bias gasket in circular groove, and the valve rod passes through valve body and is butted on anti-bias gasket, and valve deck passes through valve rod and valve
Body is fixedly connected, and the valve mechanism is simple, prevents valve rod center and valve body center from not causing valve plate by valve rod in same straight line
Top partially, guarantees the leakproofness of valve, extends valve service life.
Although one of above scheme valve leakproofness is preferable, it is less steady that an anti-bias gasket construction is only used only
It is fixed, the possibility of valve rod offset may occur after long-time use.
