Product Introduction:
Emergency relief valve: When the tank pressure accumulation imbalance due to operational errors or external fire and rain caused by emergency situations. The opening action of the emergency pressure/vacuum relief valve is as follows: When the overpressure is exceeded, the valve disc gets the upward force, the valve cover opens to relieve the pressure, and the valve disc returns to the seat seal when the pressure reaches 90% of the set pressure. When vacuum accumulates in the tank, the valve disc opens downward to release the vacuum. Similarly, when the negative pressure reaches 90% of the set pressure, the valve disc returns to the seat and reseals.
Categories:
Emergency relief valves are divided according to the pressure form: emergency pressure relief valves, emergency pressure/vacuum relief valves
Emergency relief valves are divided according to the loading form: gravity loading, projectile loading, pilot valve loading
The emergency relief valve is divided according to the opening form: hinge opening, vertical opening
7100 Emergency relief valve: 7100 emergency relief valve. Emergency protection is provided to the tank to deal with overpressure situations that the tank's standard vents cannot handle. The size of the drain valve is reasonably designed and the discharge meets the API2000 standard, which is sufficient to cope with emergency drainage caused by fire. These drain valves are also very convenient for tank inspection and maintenance. 7100 Emergency relief valve only has pressure relief function. The vacuum drain function must be provided by a standard drain facility or by a 7200 emergency drain valve with vacuum suction. If the internal pressure of the storage tank is too large, the hinged cover of the 7100 emergency relief valve begins to open when the predetermined set pressure is reached to release the excess pressure. When the overpressure dissipates, the hinged cover resets. The hinge mechanism can prevent misalignment and ensure accurate return of the hinge cover.
Features:
1.Advanced sealing technology that exceeds the most stringent industry standards for leakage tolerance (well below API2000 standards) and guarantees high set point accuracy (±3%).
2.All components can be replaced on site, including spool seals, without any special tools or complicated procedures.
3.Valve is fully open structure
4.Each 7100 emergency relief valve is certified after a rigorous factory review and leak inspection.
5.Anti-corrosion coating for the most corrosive applications.
6.Certified displacement curves prove that this series of emergency relief valves is suitable for various product sizes.
7.Available for ANSI, DIN and HG/T20592~20635-2009 flanges.
