Tungsten Carbide Valve Ball Applicability (2/2)

Theoretically, tungsten carbide ball rely on the role of the media between ball and seat have a mutual compression to achieve cut-off function. The valve seat ring at predetermined contact pressure localized plastic deformation and elastic region, so that it is possible to compensate for manufacturing precision and surface roughness of the sphere, in order to ensure the sealing performance of the ball valve. Then we introduce some common occasions of tungsten carbide ball valve:

1. In the two-position adjustment, sealing requirements of high performance, open and close rapidly (1/4 turn open and close), the larger the pressure, the operating torque, low flow resistance, cavitation or vaporization of the piping system should use tungsten carbide ball;

2. Pipeline with corrosive media;

3. In cryogenic apparatus or high-temperature and high-pressure piping systems;

4. Full bore welded carbide ball valve can be used in pipelines and gas pipelines need buried in the ground;

5. Specially designed V-shaped openings carbide ball structure may have regulatory function;

6. Petrochemical, power systems, metallurgical industry and other fields have a higher operating temperature;

7. Refined oil and natural gas transportation or storage of piping or equipment.

In addition, due to different connectors, it can be divided into carbide ball full bore or reduced diameter valve, welded ball valves, flanged ball valves, floating ball valve threaded connection. Among flanged ball valve (which is the two pipes, fittings or equipment, each fixed in a first flange, and then between the two flanges plus flange gasket, bolt the last two law Flanges tighten it closely combine a removable connector.) the most common, both in the metallurgical oxygen piping system, or in the city gas and natural gas pipeline systems have been widely used.
