Pneumatic stainless steel ball valve structure and role
Core Tip: stainless steel ball valve ball is floating, under the action of the media pressure, the ball can produce a certain displacement and pressed on the outlet side of the sealing surface to ensure that the export side of the seal. Floating pneumatic V-type ball valve structure is simple, good sealing, but the ball to bear the working medium of the load all passed to the export seal, so consider the sealing ring material can withstand the work of the ball media load. This structure is widely used in medium and low pressure ball valves.
1, floating pneumatic V-type ball valve stainless steel ball valve ball is floating in the media under pressure, the ball can produce a certain displacement and pressed on the outlet side of the sealing surface to ensure that the export side seal. Floating pneumatic V-type ball valve structure is simple, good sealing, but the ball to bear the working medium of the load all passed to the export seal, so consider the sealing ring material can withstand the work of the ball media load. This structure is widely used in medium and low pressure ball valves.

Second, the fixed ball Pneumatic ball valve Stainless steel Pneumatic ball valve is fixed, after the pressure does not produce movement. Fixed ball valve with a floating seat, by the media pressure, the valve seat movement, so that the seal on the ball to ensure that the seal. Usually with the ball on the lower shaft with bearings, operating torque is small, suitable for high pressure and large diameter valves. In order to reduce the operating torque of the pneumatic ball valve and increase the reliability of the seal, in recent years there have been oil seal ball valve, both in the sealing surface between the injection of special lubricants to form a layer of oil film, that is, enhanced sealing, Torque, more suitable for high pressure large diameter ball valve.
Third, the elastic ball Pneumatic ball valve Pneumatic ball valve is flexible.

Sphere and valve seat seals are made of metal materials, sealing pressure is very large, relying on the pressure of the media itself has been less than the requirements of the seal, you must exert external force. This valve is suitable for high temperature and high pressure medium. The elastic sphere is an elastic groove at the lower end of the inner wall of the sphere, and is elastic. When closing the channel, use the wedge of the stem to keep the ball up and the valve seat pressed to seal. Before turning the ball, loosen the wedge-shaped head, and the sphere restores the original shape, so that there is a small gap between the sphere and the valve seat, which can reduce the friction and operating torque of the sealing surface. Pneumatic V-type ball valve according to its channel position can be divided into straight-through, three-way and right angle. The latter two ball valves are used to dispense media and change the flow of media.
