‌ stainless steel safety valve

 ‌ is a kind of safety protection valve, mainly used to protect systems and equipment from excessive pressure damage. It can automatically open when the pressure in the equipment or pipeline exceeds the set value, releasing the medium pressure, so as to ensure the normal operation and safety of the system and equipment.

Type and structure

Stainless steel safety valve according to the structure can be divided into vertical hammer type, lever type, spring type and pilot type (pulse type). According to the structure of the valve body, it can be divided into two types: closed and unclosed. The medium of the closed safety valve will not leak out, suitable for toxic and corrosive media; The non-enclosed safety valve is suitable for air and steam and other media ‌

‌ Stainless steel safety valve 

has a wide range of applications in many industries, including chemical, petrochemical, pharmaceutical and food industries ‌. In the chemical industry, stainless steel safety valve is widely used in gas, liquid transportation, processing equipment and reactors need safety valve equipment, its stability and accuracy to ensure the safety of equipment and personnel ‌

In the petrochemical industry, stainless steel safety valve because of its corrosion resistance and high temperature stability, suitable for oil, natural gas and other high temperature and high pressure environment transportation and processing ‌

The pharmaceutical industry needs high quality and purity products, stainless steel safety valves can meet this requirement to avoid impurities and pollution ‌

The food industry is also widely used stainless steel safety valve, because of its health security has been recognized by the industry ‌

Application scenarios of different types of stainless steel safety valves

‌ fully enclosed safety valve ‌ : mainly used for the medium of toxic or flammable gas containers, exhaust gas all through the exhaust pipe to prevent media leakage ‌

‌ semi-closed safety valve ‌ : suitable for gas containers that do not pollute the environment. Part of the discharged gas passes through the exhaust pipe, and part leaks out from the gap between the valve cover and the valve stem ‌

‌ open safety valve ‌ : suitable for the medium is steam or does not pollute the atmosphere of high temperature gas container, the valve cover is open, is beneficial to reduce the spring temperature ‌

Installation requirements and maintenance

‌ Installation position ‌ : The safety valve should be vertically installed at the highest position of the equipment or pipeline to ensure that it can be opened in time under the highest pressure ‌

‌ Quantity required ‌ : boilers with rated evaporation capacity greater than 0.5t/h shall be equipped with at least two safety valves, and boilers with rated evaporation capacity less than or equal to 0.5t/h shall be equipped with at least one safety valve ‌

‌ maintenance ‌ : Periodically check the tightness and discharge capacity of the safety valve to ensure that it can work properly when required ‌
