Difference between electric ventilation butterfly valve and conventional ventilation butterfly valve
The utility model is characterized in that the valve seat sealing ring is composed of multiple layers of stainless steel sheets on both sides of a soft T-shaped sealing ring. The sealing surface of the valve plate and the valve seat is an inclined conical structure, and a temperature-resistant, corrosion-resistant alloy material is surfacing on the oblique conical surface of the valve plate; the structure of the spring fixed between the adjusting ring pressure plate and the adjusting bolt of the pressure plate is assembled together. This structure effectively compensates the tolerance band between the sleeve and the valve body and the elastic deformation of the valve stem under the medium pressure, and solves the sealing problem of the valve in the two-way interchanged medium conveying process.
The soft T-shaped multi-layer stainless steel plate on both sides forms a seal ring, which has the dual advantages of metal hard seal and soft seal, and has zero leakage sealing performance under both low temperature and high temperature conditions. The test proves that the positive flow state of the cell (the direction of flow of the medium is the same as the direction of rotation of the disc) is that the pressure of the sealing surface is caused by the torque of the transmission device and the pressure of the medium on the valve plate. When the pressure of the medium increases, the tighter conical surface of the valve plate and the seat sealing surface are squeezed tighter, and the sealing effect is better.
When in the reverse flow state, the seal between the valve plate and the valve seat is pressed against the valve seat by the torque of the drive device. With the increase of the reverse medium pressure, the unit positive pressure between the valve plate and the valve seat is smaller than the medium pressure, the deformation of the spring of the adjustment ring after being loaded can compensate the tight pressure of the valve plate and the valve seat sealing surface. Plays automatic compensation.
