Structural form of stainless steel ball valve

(1) The stainless steel ball valve adopts a fixed ball (shaft-supported) structure. In order to reduce the operating torque of the ball valve, enhance the reliability of the seal, and avoid displacement of the ball under pressure, the ball valve adopts the structure of a fixed ball. This structural form ensures the flexible opening and closing of the valve to the greatest extent, accurate alignment, and is not affected by the pressure of the medium.
(2) Sealing form of stainless steel ball valve: it is sealed with soft and hard laminated metal sheets, which has the dual advantages of metal hard seal and elastic seal. The special ball valve for dust discharge with automatic compensation device has very good sealing performance. The valve seat and the valve body are of a cylinder type structure, which can ensure the integrity of the contact between the sealing surface and the spherical surface to the greatest extent, thereby ensuring the life of the seal; the compensation device squeezes the sealing valve seat as a whole to the spherical surface when the seal is normally worn , Compensate the sealing gap caused by wear and tear, and also prolong the service life of the sealing surface.
(3) Drive form of stainless steel ball valve: single-cylinder double-acting cylinder is connected with unique actuator, which avoids the dead angle in the driving movement, and the super large torque generated by the large-diameter cylinder ensures the rapid opening and closing of the valve and accurate positioning. Under the premise that the air source pressure meets 0.4Mpa~0.6Mpa, the valve can be opened and closed within 5~8 seconds, achieving flexible and rapid switching.
