Heavy Hammer Plug-in Valve sluice damper
Heavy Hammer Plug-in Valve sluice damper
Technical Description of Heavy Hammer Plug Valve
1. Valve control way: field control, remote control
2. Valves are cut off in emergency and automatically opened by heavy hammer (counterweight)
3. Valve control mode: Windlass
4. Working time: 10-20s
5. Valve seal form: gas seal, high pressure (0.1Mpa) gas is injected from the outer end to form an airtight passage between the valve plate and the door frame， and sealing is achieved. Fans are provided by the demander.Gas flow basis: the clearance between the valve plate and both sides of the valve body is 2 mm, and then multiplied by the length of the required seal, thus the air outlet area is calculated. Air outlet area: specification 2400*3300 (0.036), specification 3200*4260 (0.04688), specification2600*2840 (0.03312). Because we need to maintain the pressure of 0.1 MPa, we need fan parameters: flow 120-180 m/h. Pressure 0.11 MPa
6. Anti-corrosion measures: Our company uses high-temperature anti-corrosion paint for painting.
7. Drainage measures: Drainage from the original chimney drainage wells, no additional drainage devices
