Rev. All safety valve discharge plane or the size of the object surface is seat throat cut plane or the size of the object surface. Q: spring safety valve and fault analysis of the application of answer: spring is on the exhaust pipe son did not wash the congestion because of wrong operation or and set up the device. 3. Rev. Safety valve in the opening height between micro and type with qi type. Spring is framed exhaust pressure cooker in safety pressure scope, ensure safe use of devices. ( 6) Pressure to open less than regulation. Should be taken to change the spring, such as new debugging opening pressure treatment method. Raise safety valve movement process is the proportion of the utility type, it is mainly used for liquid occasions, sometimes small gas occasions for emissions. Should reduce the discharge pipe resistance. This is mainly due to the selection of the relief valve discharge xiaoping facilities safety discharge capacity, should from the new choose appropriate safety valve; Stem midline deviation or spring rusting, the valve can not be open to the proper height, should from the new assembling the valve stem or change the spring; The exhaust pipe section is not enough, should take appropriate safety discharge plane or the size of the surface of the exhaust pipe. Open a few times, the valve can be used to improve the board took dirt away; Tightly closed surface was damaged. Should use appropriate spring stiffness; Regulating improper debugging, make the back pressure is too high. Spring loaded safety valve common faults and alleviation measures ( 1) After discharge disc does not return. ( 2) Leakage. Should from the new debugging heavy hammer position and make the lever movement. Spring of the structure, performance is the key to this valve. Should from the new assembly or change; Reduce or miss spring elastic. Should from the new debug spring compression quantity or weight; Disc and seat stick. ( 3) To the provisions of the pressure is not open. In accordance with the Industrial Valves disc to open the biggest height and diameter of the relief valve flow ratios distinguish, can be divided into the spring micro spring safety valve opening and closing high pressure relief valve and the spring and all safety valve two kinds. 2. Spring full rev safety valve full high rev safety valve opening degree of Marine valve is greater than or equal to the port of the diameter of the quarter. 。 Made two utility, which can be also used as the utility type. The constant pressure mainly inaccurate; Aging elasticity decreased. ( 5) The disc jump or oscillation frequency. Should be based on the damage degree of right, and the use of grinding or turning after grinding method to repair; Stem buckling, heeling or lever to pivot deflection, the valve core and valve disc displacement. Should from the new debugging the adjusting ring position; Drain line resistance is too large, lead to excessive emissions back pressure. 1. Spring micro micro jewels of high pressure relief valve and safety valve for opening and closing the opening height of less than a quarter, the diameter of the flow channel is commonly 1/40 a 1/20 the diameter of the runner. Should be appropriate tightening debugging screw or change the spring. ( 4) After the exhaust pressure rise. This is mainly spring buckling stem and disc to install malposition or stuck. Port by are: between disc and seat tightly closed surface dirt. Under pressure from normal office facilities, disc and seat tightly closed surface between the degree of leakage is occurred more than allowed. Should from the new assembly. Should be conducted on a regular basis for manual vent or drain relief valve; Lever of the relief valve lever stuck or heavy hammer has been moved. Mainly because of the spring stiffness is too big. Lead to this situation is comprised of constant pressure is not allowed. Its movement process is belong to two utility type, be sure to use a lift institutional capacity of the whole paper rev, full and safety valve is mainly used in the occasion of gas medium. 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.
