Melal pressure rellef and explosion-proof valve is a new type of waterproof and breathable component. The connecting rod structure
is compressed by a spring and combined with other materials such as metal and slicone rubber to form a sealed installation part itcan effectively prevent dust, water or other harmful Substances enter while maintaining pressure balance inside and outside theequipment, it has the advantages of rapid pressure relief and explosion-proof, high precision of initiation point automatic reset afterblasting, stable performance, simple installation, and extended product life cycle.
working principle:
When the sealed cavily is in normal operation, under normal internal pressure conditions, Shangda pressure relief products continueto exhaust the sealed cavity, waterproof, dustproof and breathable. The working principle is the same as that of the traditional ventvalve. Under normal conditions,the external ambient temperature rises, which leads to the increase of the intermnal pressure of thesealed cavity and the outward flow of air. On the contrary, when the extermal ambient temperature decreases, the internal pressure ofthe sealed cavity decreases and the air enters the cavity, at the same time, the pressure relief vaive is built with e-PTFE membranecomponent, which is dustproof, liquid-proof and antifouling.
dyed and granulated.
When the intemal pressure of the sealed cavity rises sharply and exceeds the set blasting value during abnormal operation, a largeamount of gas pushes Shangda pressure relief product to instantly complete direct connection with the outside, and a large amount ofgas is discharged to quicKly release the strong pressure inside the sealed cavity to avoid explosion and reduce explosion damage. Inaddition, Shangda pressure relief product has high explosion point precision and can automatically reset to continue to use theprotective sealing body to reduce maintenance cost.
