Q347固定式球阀简介 I. Introduction to Q347 Fixed Ball Valve

   都带有浮动阀座,受介质压力后,阀座产生移动,使密封圈紧压在球体上,以保证密封。 Fixed ball valves are equipped with floating valve seats. After the pressure of the medium, the valve seat moves, so that the sealing ring is tightly pressed on the ball to ensure the seal. Bearings are usually mounted on the upper and lower shafts of the ball, and the operating torque is small, which is suitable for high pressure and large diameter valves. 电动球阀 In order to reduce the operating torque of the ball valve and increase the reliability of the seal, oil-sealed ball valves have appeared in recent years. The special lubricating oil is injected between the sealing surfaces to form a layer of oil film, which enhances the seal and reduces the operating torque. , More suitable for high pressure large diameter electric ball valve .
