Introduction to the selection principle of high platform ball valve
How to choose the principle of high platform ball valve! The high-platform ball valve not only has a simple structure and good sealing performance, but also has a small volume, a light weight, a small material consumption, a small installation size, a small driving torque, a simple operation, and an easy opening and closing in a certain nominal dia
meter range. It is one of the fastest growing valve varieties in the past decade.
Flange high platform ball valve
1. The main line for the transportation of oil and natural gas, which needs to be cleaned of the pipeline, and which needs to be buried underground, select the high-platform ball valve with full-dia
meter and all-welded structure; if it is buried on the ground, choose the full-dia
meter welded connection or flange connection. High-platform ball valve; branch pipe, flange connection, welded connection, full-dia
meter or reduced-dia
meter high-platform ball valve.
Second, the delivery pipeline and storage equipment of the refined oil, the flanged high platform ball valve is selected.
Third, the city gas and natural gas pipelines, the use of flanged and internal threaded floating ball valve.
Fourth, the oxygen pipeline system in the metallurgical system should be selected after strict removal
5. For low temperature medium piping systems and devices, a low temperature ball valve with a bonnet should be used.
6. On the pipeline system of the catalytic cracking unit of the refining unit, a lifting rod type ball valve may be selected.
7. In the equipment and piping system of acid and alkali and other corrosive media of chemical system, it is preferred to use all-stainless steel ball valve made of austenitic stainless steel and PTFE as valve seat seal.
8. Metal-to-metal sealed ball valves may be used on the piping systems or devices of high-temperature media in metallurgical systems, power systems, petrochemical plants, and urban heating systems.
Nine, when the flow adjustment is required, a worm-gear-driven, pneumatic or electric adjustable high-platform ball valve with a V-shaped opening can be selected.
