High temperature ball valve

The high temperature ball valve is a metal sealing structure, the sealing form is a metal to metal seal, and the metal sealing ring can be exchanged to metal sealing, and the sealing ring of the stainless steel plate and the graphite composite plate is sealed to the metal. Hard seal butterfly valve drive form in addition to the power of manual, worm gear drive, pneumatic, etc.. High temperature ball valve butterfly plate installed in the direction of the diameter of the pipe. In the hard sealing ball valve body cylindrical channel, the disc shaped disc around the axis of rotation, rotation angle of 0 degrees ~90 degrees, between the rotation to 90 degrees, the valve is fully open state.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact. No Information The sealing ring is characterized in that the valve seat sealing ring is composed of a plurality of layers of stainless steel sheets on both sides of the soft T shaped sealing ring.
The sealing surface of the valve plate and the valve seat is an inclined conical structure, which is welded with a temperature resistant and corrosion resistant alloy material on the surface of the valve plate oblique cone. This structure effectively compensate for the elastic tolerance between the sleeve and the valve stem in the medium zone and deformation under pressure to solve the problems existing in the process of sealing the valve in the two-way exchange medium transmission.
The soft T type double layer stainless steel sheet is used to form a sealing ring, which has the advantages of both metal hard seal and soft seal. The test proves that the pressure of the sealing surface is the moment of the driving device and the effect of the media pressure on the valve plate when the positive flow state of the pool is the same as the direction of the medium flow and the direction of the butterfly plate rotates. Positive medium pressure increases when the valve plate oblique cone surface and the valve seat sealing surface squeezed more tightly, the sealing effect is better.
When the counter current state, the valve plate and the valve seat between the sealing by the torque to drive the valve plate to the valve seat. With the reverse medium pressure, valve plate and seat unit between the positive pressure is less than the medium pressure, the adjustment ring spring deformation under loading of the stored energy compensation valve plate and valve seat sealing surface of the tight pressure to play the role of automatic compensation.
Therefore, the utility model unlike the existing technology, software and hardware installed in the valve plate multi ring, but directly installed on the valve body, the middle seat in the plate and an additional adjustment ring is a very good way of two-way seal. It will replace the gate valve, and the ball valve.
