Welding valve is used in many equipments, but many people don't know what its main function is.

The welding valve has four main functions: start and stop flow; control medium flow; and prevent backflow or reverse flow, which is used to adjust the pressure or discharge of the fluid. The selection of a building's piping system can be based on temperature, medium type, temperature and other factors.

For the enterprise high-rise building fire hydrant control Welded ball valve Different signal valves should be used, which is related to whether the fire hydrant system can be reasonably selected and used in case of fire. The control valves of the fire hydrant system are set as signal valves, and the open state of all welded ball valves can be displayed in the fire safety control research center, so as to facilitate students' management and accounting personnel to inspect, although the project cost has been improved.

However, the investment or the proportion of the whole fire hydrant system is small, which can greatly improve the safety of the whole fire hydrant system. This investment is worth the investment.

Welding one Globe valve It is mainly applied to cut off or connect the network medium in various working conditions of petroleum, chemical, hydraulic and fire control power stations with nominal high pressure pn10.0 ~ 32.0mpa and P (54) 100V ~ p (57) 170V, working environment temperature ≤ 540 ℃ (in which p (57) 170V works at 570 ℃). Suitable for other media: water, oil, steam, etc. Operation and management methods are: manual, gear transmission, electric, etc.
