Raise the difference between the type and the rev safety valve what is raise safety valve is refers to the trace of the opening height of the relief Industrial Valves is, suddenly are not allowed to open or close the 'water hammer' phenomenon, is mainly used in liquid medium; He is typical of the import and export diameter is the same. What is the rev safety Industrial Valves when rise to the valve core and valve seat ring size of seat diameter area ( Increase the height of the x circumference of the sealing face of valve core area = area of the sealing face of valve core) Are all open; Its typical characteristics is exports diameter greater than imports. A, enlightening the safety valve and safety valve of the main difference is different, the height of the opening in the general raise safety valve opening height of the seat of the throat diameter of 1/20 ~ 1/40, while the rev safety valve opening for the seat more than a quarter of throat diameter. Second, the selection of note: a, the safety of the emissions of the relief valve must be greater than container discharge capacity; B, absolutely smooth operation pressure of containers, should consider to choose raise safety valve ( Such as compressor cylinder) ; C, high pressure vessel, large containers, and in large volumes of water safety, low pressure container, had better choose the rev safety valve ( Such as the reaction kettle equipment) 。 Three, the relief valve opening is to point to: disc leave the actual lift in the closed position.
