Connect, sealing ring is engaged with dish plate.
Three-eccentric-butterfly-valve while the valve rod shaft core position of double eccentric disk valves is eccentric, make the circular cone profile shaft of butterfly plate sealing surface
Line is inclined to body cylinder axis so that the sealing section of butterfly plate is no longer proper circle but ellipse, its sealing surface shape also because
This is asymmetric：While favouring body central line, another side then parallel to body central line.So as to cause the close of three-eccentric-butterfly-valve
Envelope construction is changed into torsion sealing from position seals, and it fully relies on the contact face pressure of valve seat to reach sealing effectiveness, with double bias
The elastic deformation of the dependence valve seat of dish valve reaches that sealing effectiveness is differed completely, and due to the contact face pressure and the pressure of medium of valve seat
Power is to be directly proportional, therefore, and three-eccentric-butterfly-valve can be used in the environment of HTHP.Existing three-eccentric-butterfly-valve when in use,
There is following defect, its drive device housing is the preferable enclosed construction of water proofing property, the worm reducer work shelves one in it
It is fixed, when needing to adjust the chip arrange parameter of worm reducer work shelves, it is not easy to open drive device housing, adjustment operation
Bother very much.
