A SURGE RELIEF VALVE OF FLUID RECOVERABLE TYPE AND THE SYSTEM

摘要

PURPOSE: A fluid recoverable surge relief valve and a system thereof are provided to prevent surge with decreased pressure in a pipe by discharging fluid to the outside when the pressure is over a set pressure. CONSTITUTION: A fluid recoverable surge relief valve comprises a gate valve(10), a diaphragm assembly(20), and a sealed cover(30) for preventing diffusion. The gate valve is installed in one side of a main pipe(1) to control the inflow of fluid. The diaphragm assembly is installed in an outlet(12) of the gate valve to discharge the fluid when the pressure of the main pipe is over a set pressure. An air suction port(31) is formed on the top of the sealed cover for preventing diffusion and a discharge port(32) for fluid recovery is formed on the bottom there. The fluid discharged through the outlet of the gate valve is recovered through the cover for preventing diffusion.
