The relief valve is a safe, try to take care of with valve, it is under the open-close part affected by external force effectiveness of normally closed, when the medium pressure inside the facilities or pipe, e. semi-automatic open, when more than after discharge medium system to avoid the pipeline or facilities within the medium pressure in excess of the prescribed number. Safety Industrial Valves before installation should be specialized testing, and seizing the officer tightly closed. Relief valve belonging semi-automatic valve, relief valve is mainly used in boilers, pressure vessels and piping, stem pressure shall not exceed the specified value, security and facilities for personal life running up the matter to take care of utility. The relief valve installation and protection should be paid attention to the following projects: all kinds of safety valve should be installed straight. 。 The relief valve should be of use in seizing on a regular basis. Medium of the closed type safety valve that is out of drain, all along the export to the designated place of drain, normally used in the toxic and corrosive medium. For spring safety valve, in a nominal pressure ( PN) Have several office pressure level within the range of the spring, when placing order, in addition to indicate the relief valve model, name, medium and temperature, it should indicate the valve tightly closed pressure, otherwise according to the maximum confining pressure supply tight. Relief valve according to the structure to points, divided into vertical hammer, lever, spring type and leading type ( Electronic pulse type) ; According to the body construction points, can be divided into closed type and close type two kinds of Marine valves. For with air and steam safety valve, think more suitable and use not closed safety valve. Q: the installation of safety valve protection and pay attention to the things of project answer: open the relief valve disc height can be divided into micro enlightening the safety valve and the safety valve, raise safety valve opening stroke height is: 0 or less. 05D0( Minimum discharge throat diameter) ; All safety valve opening height is 0 or less. 25D0( Minimum discharge throat diameter) 。 Should not prevent the safety valve outlet, prevent the initiation pressure phenomenon. For the selection of valve products, should according to the actual tightly closed pressure to confirm. 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. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center.
