The relief valve should be installed vertical and close to be try our best to take care of the facilities or pipe. 。 For ordinary spring type safety valve, the back pressure is less than the relief valve set pressure value of 10 to one hundred percent. The outlet pipe of the preset should ponder question back pressure not to exceed constant pressure relief valve of a certain value. Q: the installation of safety valve and the preset point answer: when the relief valve is equipped with block valves at the inlet piping, should choose single disc gate valves, and seal, valve stem water should be no danger, lest the valve stem and valve plate cosignatory pin corrosion or relaxation, the valve plate. Into the tightly closed system relief valve outlet pipe should be suitable medium to 45 & amp; 度; Taper at the top of the main emissions, so that the total tube condensate flow into the branch pipe, and can detract from the relief valve back pressure. When the relief valve with by-pass valve, the valve should be seal clearance. When the torch into the vent duct or to internal heat. Relief valve inlet pipe shall be deemed appropriate and use the long radius elbow. If not can find a place close to, from be try our best to take care of facilities or pipe to relief valve inlet pipeline total pressure drop, should not be more than 3 one hundred percent of the relief valve set pressure value. Medium with condensate or condensable gases, the export of safety valve should be higher than the main pipe; Otherwise, drainage should be taken to deal with the relief Industrial Valves should be set to check repair platform, weight placed the relief valve should ponder question when the relief valve is Marine valve can be disassembled, hoisting, indispensable should be set when the boom. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
