Ball came is birth in Century 50 years, with the rapid development of China valve manufacturer the continuous improvement of production technology and product structure.Today, we'll look at a few kinds of ball valve. The first is called a floating ball valve ball is floating, which, in the medium under pressure, can produce some displacement of the sphere and pressed in the export side of the sealing surface, to ensure the export side seal. Floating ball valve is of simple structure, good sealing, but the ball under the load of work all the media to pass the export ring, so to consider the ring material can withstand the work load of the media sphere, under high pressure shock, the ball may shift. The second is called the fixed ball ball valve, the ball is fixed, no movement after compression. Fixed with a floating ball valve ball valve seat, by the media pressure, the valve seat have a mobile, so that the sealing ring is pressed on the sphere, in order to ensure the sealing. The third is called the stainless steel ball valve, is characterized by compact structure, reliable sealing, simple structure, convenient repair, sealing surface and spherical often in the closed state, can not easily be medium erosion, easy to operate and repair, suitable for medium to water, solvents, acids and natural gas general working.
