Spring welded high pressure safety valve，Welded high pressure safety valve，Safety valve

‌ spring welded high pressure safety valve ‌ is an important safety protection device, widely used in pressure vessels and pipeline systems, used to automatically release the medium when the pressure exceeds the set value, to prevent equipment overpressure damage or even explosion accidents. Its technical features include:

‌ material selection ‌

 : imported high quality materials, such as stainless steel or alloy steel, to ensure that the valve body and spring have high strength and corrosion resistance, to adapt to a variety of harsh working environment ‌

‌ Structure features ‌ 

: The spring is directly welded in the valve body, avoiding the threaded connection and other factors that may lead to leakage, improve the tightness and reliability of the safety valve. In addition, the utility model has the advantages of compact structure, convenient installation, small size, light weight, easy installation and maintenance ‌

Working principle

The working principle of the spring welded high pressure safety valve is based on the elastic deformation of the spring. Under normal working pressure, the reaction force generated by the spring is greater than the medium pressure, and the safety valve is closed. When the system pressure rises to the set value, the medium pressure overcomes the reaction force of the spring, pushes the valve disc open, and releases the excess medium to the atmosphere or other safe areas, thereby effectively preventing the system from overpressure. When the system pressure drops below the set value, the reaction force of the spring is greater than the medium pressure, the valve disc will automatically close and return to the sealed state ‌

‌ spring welded high pressure safety valve has a wide range of applications in many high pressure industries, mainly including petrochemical, electric power and metallurgy industries ‌. In the petrochemical industry, it is used for the safety protection of equipment such as high-pressure reactors, storage tanks and pipelines to prevent accidents caused by overpressure ‌

In the power industry, spring welded high pressure safety valve is used for the safety protection of boilers and steam turbines and other high pressure equipment to ensure that the steam pressure is within the safe range ‌

In the metallurgical industry, it is used for the safety protection of high-pressure vessels and pipelines to ensure the safe operation of production equipment ‌
