High to what degree and the valve structure and material selection are all related, should be based on the interpretation of the manufactory understand. 6. To ensure open pressure value is correct, should make debugging medium conditions, such as media category, such as temperature as possible close to the actual operating conditions. Change in media category, especially when media accumulation state is not the same ( For example, from a liquid into a gas phase) , the opening pressure often change. Q: how to debug the relief valve opening pressure answer: 1. At level indicate the office of the spring pressure range, after turning adjustment screw change amount of spring compression, can the opening pressure adjustment. 2. Safety valve before delivery, should by testing its opening pressure to the user requirements of setting value. Office at higher temperatures, the opening pressure of ordinary corner. 5. Turn adjusting screw in screw before, should make the valve inlet pressure to reduce to 90 opening pressure to less than one hundred percent, in order to avoid spin turn adjustment screw when the disc is help and rotate, causing damage to tightly closed surface. 3 use on will be try our best to take care of the relief valve installed to the facilities before or before installing, be sure to present the new installation debugging, to determine the guard of the whole valve set pressure value is required. If users spring office stress level, the force level according to ordinary pressure should be according to the lower limit of debugging. So debugging and when used in high temperature, at room temperature under normal temperature setting pressure value should be slightly higher than the requirement of the opening pressure values. 4. Common sense fixed attached with back pressure relief valve used in occasions, when after inspection experience debugging opening pressure ( The back pressure to atmospheric pressure) , the whole Marine valve setting value shall be the requirements of opening pressure value minus the supplementary with back pressure. 。 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.
