Should reduce the discharge pipe resistance. ( 5) The Marine valve disc don't return after discharge. Common fault and disposal measures as follows: ( 1) Leakage. Should from the new debug spring compression quantity or weight; Disc and seat stick. Should from the new assembly or change; Reduce or miss spring elastic. 。 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. Speckle pipe valve failure is mainly comprised of presupposition, production, selection, or caused by using inappropriate. 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. Open a few times, the valve can be used to improve the board took dirt away; Tightly closed surface was damaged. Should be appropriate tightening debugging screw or change the spring. ( 2) To the provisions of the pressure is not open. This is mainly spring buckling stem and disc to install malposition or stuck. ( 4) After the exhaust pressure rise. Mainly because of the spring stiffness is too big. ( 6) The disc jump or oscillation frequency. Should from the new debugging heavy hammer position and make the lever movement. Should be taken to change the spring, such as new debugging opening pressure treatment method. When the pressure inside the vessel to the allowed value, the Industrial Valves and semi-automatic closure, the beginning and end of the internal pressure vessels is lower than the maximum allowed pressure, semi-automatic avoid due to overpressure may manifest an accident, so the stripes pipe valve is also known as pressure vessel last try our best to take care of equipment. Q: striped tube valve common fault and disposal way of answer: striped tube is a kind of relief valve by the import static pressure on the semi-automatic relief preparedness protection device, it is one of the most shut the safety accessories for pressure vessels, its function is: when the pressure in the vessel exceeds a certain value, depends on the media's own pressure semi-automatic open valve, quick discharge medium of a certain number of. Should use appropriate spring stiffness; Regulating improper debugging, make the back pressure is too high. ( 3) Pressure to open less than regulation. Than these failures such as bridge, and affect the valve and the survival of the fixed number of year, even can not ensure the safety try our best to take care of the utility. Should from the new assembly. 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. 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. The constant pressure mainly inaccurate; Aging elasticity decreased. Lead to this situation is comprised of constant pressure is not allowed. Should from the new debugging the adjusting ring position; Drain line resistance is too large, lead to excessive emissions 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.
