Application of ball valve ball
The valve ball is used to control the fluid flow state in the fluid transportation pipeline. Because the valve ball has a simple structure, easy installation and maintenance, good sealing performance, no internal leakage, and small size, it is loved by market users. So what are the applications of valve spheres?
Since the valve seat sealing ring of the valve ball is generally made of plastic, when selecting the structure and performance of the ball valve, the fire resistance of the ball valve should be considered, and the ball valve should be used in the equipment and piping system of flammable and explosive media. , More attention should be paid to fire prevention.
The valve ball is suitable for low pressure cut-off, light structure, corrosive medium pipeline system. Valve balls can also be used in cryogenic devices and piping systems. The
In the oxygen pipeline system of the metallurgical industry, the valve ball needs to undergo strict degreasing treatment during use. When the main line in the oil pipeline and gas pipeline needs to be buried underground, full-diameter welded valve spheres are required. When the adjustment performance is required, a valve ball with a special structure with a V-shaped opening should be selected.
