Measures to improve the sealing performance of stainless steel ball valves
What standard can reflect the good or bad sealing performance of stainless steel ball valves? We all know that the key function of the vast majority of valves is to disconnect and connect the transportation of media. In order to ensure that media leakage is not easy to occur, the sealing performance must be good. Leak prevention is a major technical indicator value of valves.
Stainless steel spheres require common questions based on the following aspects:
The stainless steel ball has three different sealed Zibo series bearings:
(1) The joint between the filling material and the Zibo series bearing seat
(2) The junction between the sphere and the valve cap
(3) The contact point between the protruding surface of the high-pressure gate valve and the opening and closing components
The leakage at the first and second locations is known as exposure, which leaks the medium inside the valve to the outside, contaminating the natural environment and causing unexpected safety accidents. It is definitely not allowed for the leakage of harmful or flammable and explosive media in the Zibo series bearing. The ball must have very good sealing performance in the Zibo series bearing.
The third leakage of the Zibo series bearing is called Zibo series bearing leakage, which is caused by the lack of relevant Zibo series bearings when turned off, and will seriously affect the actual effect of the valve Zibo series bearing door.
