Features of D371X Wafer Butterfly Valve

1. The D371X wafer soft sealing butterfly valve seat sealing ring is composed of multi-layer stainless steel sheets on both sides of the soft T-shaped sealing ring.

2. The sealing surface of the valve plate and the valve seat is an inclined conical structure, and the temperature-resistant and corrosion-resistant alloy materials are surfacing on the inclined conical surface of the valve plate; it is fixed on the adjusting ring pressure plate.

The structure in which the spring in between is assembled with the adjusting bolt on the pressure plate. This structure effectively compensates the tolerance zone between the bushing and the valve body and the

The elastic deformation under the mass pressure solves the sealing problem of the valve during the two-way exchange of the medium conveying process.

3. The sealing ring is composed of multi-layer stainless steel sheets on both sides of the soft T-shaped, which has the dual advantages of metal hard sealing and soft sealing, no matter at low temperature or high temperature

In all cases, all have zero leakage sealing performance. When the test i proves that the pool is in a positive flow state (the direction of medium flow is the same as the direction of rotation of the disc), the sealing

The pressure on the surface is generated by the action of the torque of the transmission and the pressure of the medium on the valve plate. When the positive medium pressure increases, the inclined conical surface of the valve plate and the valve seat

The tighter the sealing surface is squeezed, the better the sealing effect.

4. In the reverse flow state, the seal between the valve plate and the valve seat is driven by the torque of the driving device to press the valve plate against the valve seat. As the reverse medium pressure increases,

When the unit positive pressure between the valve plate and the valve seat is less than the medium pressure, the deformation stored by the spring of the adjusting ring after being loaded can compensate for the tightness between the valve plate and the valve seat.

The tight pressure of the cover plays an automatic compensation role.

5. Therefore, the utility model is not like the existing technology, which installs the soft and hard multi-layer sealing ring on the valve plate, but directly installs it on the valve body, and installs it on the pressure plate.

The addition of an adjusting ring between the valve seat and the valve seat is an ideal two-way hard sealing method. It will replace gate valve and ball valve
