Safety of the pneumatic valve jump value is how much, how to adjust

security pneumatic valve is a kind of automatic pneumatic valve, its role is to ensure that the machine or equipment from damage due to overpressure. Safety pressure jump of pneumatic valve in working pressure p p. The MPa, should be. ~。 Times the working pressure; When the work pressure & lt; 。 The MPa, should be. ~。 Times the working pressure. When pressure is more than a specified value, pneumatic valve will automatically open, excluding some gas pressure recovery, pneumatic valve will automatically shut down. Security pneumatic valve before installation, should according to the using situation after debugging must install and use. Pneumatic valve safety check at least once a year in general.
security pneumatic valve appropriate adjustments on the system, and under the working pressure shall not be leakage, and then make a seal.
security pneumatic valve spring and leveraged two. Spring loaded safety pneumatic valve pneumatic valve disk and seat sealing by spring force; Pneumatic valve seal is leveraged security forces by the heavy hammer by leverage. Pneumatic valve spring type safety is through the upper part of the adjusting screw change degree of compression spring, compression spring, jump the pressure. After takeoff pressure adjusted the lock nut should be tighten, prevent adjustment screw loose, make the jump pressure change on its own. Should cover the cover at the same time, to seal, shall not be any change again. Pneumatic valve lever safety is through the heavy hammer on the lever position or change the weight of the heavy hammer to adjust the pressure jump. After adjust should add fixed, and placed in a tin box to protect it, to prevent the move position.
