What is an explosion-proof valve?
The explosion-proof valve, also known as a pressure relief valve or breather valve, is a safety protection device installed on closed containers such as storage tanks, pipelines, reactors, etc. Its core function is to:
Automatically adjust the pressure difference between the inside and outside of the container to prevent equipment damage caused by overpressure or negative pressure;
Emergency relief: When the internal pressure exceeds the set value, quickly open to release the medium to avoid explosion accidents;
Respiration: Under normal operating conditions, gas is allowed to enter and exit, maintaining pressure balance within the container.
In simple terms, an explosion-proof valve serves as the “safety valve” for a container, capable of both “exhaling” (venting and pressure relief) and “inhaling” (air replenishment to prevent vacuum).
Application areas of explosion-proof valves
Explosion-proof valves are widely used in the following industries and scenarios:
1️⃣ Petrochemical industry
Storage tank area: Breather valves are installed on the tops of crude oil, refined oil, and chemical product storage tanks to prevent oil and gas evaporation and tank deformation.
Pipeline system: Pressure relief valves are installed at key nodes of oil/gas pipelines to prevent water hammer or abnormal pressure rise.
2️⃣ Energy and Electricity
Transformer: Large oil-immersed transformers are equipped with explosion-proof valves to prevent oil tank explosions in case of internal faults.
Boilers and pressure vessels: Steam boilers, heat exchangers, etc. must be equipped with safety valves (i.e., pressure relief valves).
3️⃣ Pharmaceuticals and Food
Fermentation tank and reaction kettle: Control the gas pressure generated during the process to ensure a sterile environment.
Liquid storage tank: Prevents vacuum collapse caused by cleaning or temperature changes.
4️⃣ Environmental protection and water treatment
Biogas storage tank: Regulate pressure fluctuations during biogas collection to ensure safety.
Wastewater treatment tank: An explosion-proof valve is installed on the ventilation pipe to prevent the accumulation of harmful gases.
5️⃣ Aerospace and Military Industry
Fuel tank: used for pressure balancing and emergency relief in rocket and aircraft fuel systems.
Ammunition depot: Explosion-proof valves are used at the explosion vent to reduce the damage caused by explosive shock waves.
6️⃣ Architecture and Fire Protection
Dust explosion protection system: In dusty environments such as grain processing and wood workshops, explosion relief valves are installed on pipelines.
Fire protection pipe network: Pressure relief valves are used in the pressure stabilization system to protect water pumps and pipelines.
