273mm 273mm Carbon steel Carbon steel pressure relief valve pressure relief valve to act on the internal medium trouble flap above the loading mechanism force is greater than the force exerted on it, so the valve off its seat, the safety valve opens, the medium within the apparatus through the valve seat discharge. 273mm steel pressure relief valve has a maximum working pressure of the system is not inferior to the normal operating pressure exceeds this value, it will install a pressure relief valve, once the system pressure exceeds the internal media has opened the sealed portion of the diaphragm discharge medium pressure vent out , when the pressure is normal, the spring force of the diaphragm seat next time. 273mm steel pressure relief valve is an important component warehouse roof dust protection, and play a security role in the system. Pressure release valve when there is an exception to the silo structure when pressure is endangering safety pressure valve is the last line of defense. 273mm steel pressure relief valve at its opening and closing pieces by the external force is normally closed state, when the media pressure equipment or pipeline increases, exceeds the value is automatically turned on by the media outside the system to prevent the discharge pipe or inside the equipment medium pressure exceeds a predetermined value. Relief valves are automatic valves, mainly for boilers, pressure vessels and piping, control pressure does not exceed the value of personal safety and equipment operation plays an important protective role. 273mm steel pressure relief valve can be adjusted cabin was deputy pressure equilibrium with the outside air pressure inside the silo, the effective protection Silo Safety. Silo system pressure relief valve means essential. When the air pressure inside the silo high or too low, and reaches the preset value, the pressure relief valve will automatically open, the pressure balance inside and outside of the silo, silo and its ancillary equipment to avoid being damaged. After the pressure is back to normal, the pressure relief valve will automatically recover the whole process without human intervention.
