Those problems that need to be paid attention to for forged steel valves

For forged steel valves, attention should be paid to the problems of valve body drainage and thread plugging pressure relief. After the valve pressure test, the gas and moisture in the valve cavity of the sealed cavity will increase in pressure due to the increase in ambient temperature.

Solutions to difficult opening and closing of large-caliber valves

1. Analysis of the reasons for the difficulty of opening and closing large diameter valves:

Analysis of valve market environment

According to the analysis of the valve market environment, the difference in valve consumption characteristics has led to a large difference in the development speed of the valve industry in developed and developing countries.

Pneumatic ball valve and pneumatic butterfly valve are more pros and cons

The pneumatic ball valve is a sphere, which uses the sphere to rotate 90° around the axis of the valve stem to achieve the purpose of opening and closing. Pneumatic ball valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The pneumatic ball valves designed with V-shaped openings also have a good flow adjustment function.

Where are the pneumatic cryogenic ball valves mainly used?

Pneumatic cryogenic ball valve is used to output liquid cryogenic medium such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc.

Electric eccentric hemispherical valve products and maintenance methods

Electric eccentric hemispherical valve uses eccentric valve body, eccentric sphere and valve seat, and the valve stem is automatically centered on a common track when it rotates, and the closing process becomes tighter and tighter, fully achieving the purpose of good sealing.

What is a high pressure gate valve? What are its characteristics?

The opening and closing part of the high-pressure gate valve is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The movement form of the valve stem includes a lifting rod type-the valve stem is raised and lowered, and the hand wheel does not lift, and there is also a lifting rotating rod type-the hand wheel and the valve stem rotate and lift together, and the nut is arranged on the valve body.
