What are common fire pneumatic valve

(1) gravity type fireproof pneumatic valve. Is divided into rectangular and circular. Fire prevention is often a short state of pneumatic valve at ordinary times.
when need to open the pneumatic valve, unscrew the locking bolt in front of the reeds, hand lever, roll up the pneumatic valve plate or blade, fusible piece is connected, straighten self-locking reed, tighten bolts after fire pneumatic valve back to normal working condition.
2) spring loaded fireproof pneumatic valve. Spring loaded fire pneumatic valve with rectangular and round two.
when need to open the pneumatic valve, the packed fusible piece and temperature fuse, shaking up the blade or pneumatic valve plate and fixed on the temperature fuse the soft-core, fire pneumatic valve was back to normal working condition.
3. Spring type fire pneumatic valve adjustment. Has two kinds of rectangular and circular. Normally open at ordinary times as fire regulating pneumatic valve of air volume adjustment, when a fire and air temperature is higher than ℃, fusible piece fuse, the fuse pin lay a clutch plate, clutch release, at the ends of the shaft torsional spring release, pneumatic valve closed blade.
(4) smoke fire pneumatic valve adjustment. Has two kinds of rectangular and circular. There is a requirement for smoke fire can be applied to air conditioning and ventilation system, the construction and fire prevention regulating pneumatic valve basic same, reset the way and method of air volume is the same as the fire regulating pneumatic valve.
5. Fire tuyere. Are fire requirements of ventilation and air conditioning system applied to the air supply outlet and inlet and exhaust FengKouChu.
6 pneumatic fireproof pneumatic valve. To be used with halogenated and automatic fire extinguishing system of ventilation and air conditioning duct muscle. Pneumatic fire protection system must be first pressure relief valve manual reset, reset, open again.
7 electric fire pneumatic valve. Installed in a fire on the requirements of ventilation and air conditioning duct, there is a fire when the power cut off and reset spring immediately close the pneumatic valve. Pneumatic valve can open reset after the power supply.
today electronic control smoke fire pneumatic valve. Using the technology of electronic technology and the logic circuit. Fire automatic open or closed, and alarm automatically. The controller is adopted to one or more smoke fire pneumatic valve control.
