Structural Form Of Stainless Steel Ball Valve

3 Piece Ball Valve The sealing ring adopts a combination of soft and hard laminated metal sheets, which has the dual advantages of metal hard seal and elastic seal. The ash-unloading ball valve with automatic compensation device has excellent sealing performance. The following is an introduction by Liangtai on the structural form of the stainless steel ball valve, as follows:

1. The stainless steel ball valve adopts a fixed ball (shaft-supported) structure. In order to reduce the operating torque of the ball valve and enhance the reliability of the seal, and avoid displacement of the ball after being compressed, the ball valve adopts a fixed ball structure. This structural form maximizes the flexibility of valve opening and closing, accurate positioning, and is not affected by the size of the medium pressure.

2. Stainless steel ball valve sealing form: It adopts a combination of soft and hard laminated metal sheets, which has the dual advantages of metal hard seal and elastic seal. The ash-unloading ball valve with automatic compensation device has very excellent sealing performance. The valve seat and the valve body are cylinder-type structures, which can maximize the integrity of the contact between the sealing surface and the spherical surface, thereby ensuring the life of the seal; the compensation device squeezes the sealing valve seat onto the spherical surface as a whole under the condition of normal seal wear, compensating for the sealing gap caused by wear, thus extending the service life of the sealing surface.

3. Stainless steel ball valve drive form: single-cylinder double-acting cylinder connected actuator, avoiding dead angles in the pushing movement, plus the large torque generated by the large-diameter cylinder, ensuring the rapid opening and closing of the valve and accurate positioning. Under the premise that the gas source pressure meets 0.4Mpa~0.6Mpa, the valve can be opened and closed within 5~8 seconds, achieving flexible and rapid switching.
