Safety valve is how much the jump value, how to adjust? A: The safety valve is an automatic valve, its role is to ensure that the machine or equipment will not be damaged due to overpressure. Safety valve take-off pressure at the working pressure p ≥ 0.6MPa, should be 1.05 to 1.1 times the working pressure; working pressure when the safety valve should be adjusted on the system should not leak under working pressure, and then be sealed . Safety valve spring and lever type two. Spring-loaded safety valve disc and valve seat seal by the spring force; and lever-type safety valve seal by heavy hammer through the lever force. Spring-loaded safety valve is through the upper part of the adjustment screw to change the degree of compression of the spring, the compression spring is taking off the pressure rise. After the take-off pressure is adjusted, the lock nut should be tightened to prevent the adjustment screw from loosening, so that the take-off pressure can be changed by itself. At the same time should be covered with the shell, be sealed, can not be arbitrarily changed. Lever lever relief valve is by hammer position on the lever or change the weight of the weight to adjust the take-off pressure. After adjustment should be fixed, and placed inside the iron box to protect against unauthorized removal of the location.
