Damper works: When the temperature of the gas pipeline has reached delivered fusible metal melting temperature fusible sheet fuse, damper manufacturers, compression spring and spring pin on the mandrel quickly lay their clutch plate, which When the clutch is disengaged and leaves the adjustment mechanism, since the body is equipped with two torsion springs, production fire damper, the blades rotate by torque occurs. Thus, the damper actuator mechanical drive principle, no electricity, gas and other energy, long-term supply dampers, which can ensure the fire can play a role in any case. Choice points: 4 selection of valve should pay attention to the valve's function, normally open or normally closed, automatically shut down on, manually shut down open, manual reset, signal output, remote control and other requirements. 5. If the valve and fan interaction should be used with double micro-switch device. 6. The body should be steel blade thickness of 2 ~ 6mm, dampers, body of non-combustible material, rotating parts should be corrosion-resistant metal material, and flexible rotation. Valve shell thickness not less than 2mm. Yi Rong parts in accordance with recognized standards of the fire department.
