The thrust bearing is added inside the pneumatic ball valve. The addition of this part has a good auxiliary effect on the internal friction force. Under the structural operation of this part, the friction force on other parts of the equipment can be reduced, so that the use of such equipment can be reduced to the minimum energy consumption, and long-term use can also maintain better stability and flexibility, In addition, the unique lubrication products inside the equipment have greatly protected the safety of other ball valve parts inside, and extended the service life of the ball valve.

What is the sealing principle of electric ball valve? The sealing principle of electric ball valve is mainly different according to its structure. Common ball valve structures can be roughly divided into floating ball valve and fixed ball valve. The ball of the floating ball stainless steel ball valve is freely supported on the valve seat. Under the pressure of the fluid, the ball moves in the direction of fluid movement, making it more closely touch the sealing surface of the valve seat, that is, the specific pressure on the sealing surface increases, forming a single-sided seal. At the same time, the specific pressure on the sealing surface of the valve seat in front of the valve decreases correspondingly, often not ensuring sealing. In the fixed ball valve, the ball has upper and lower rotating shafts and is fixed in the ball bearing, Follow the trajectory of the ball valve.
