Brief introduction：
Pressure relief opening of protective zone of gas fire extinguishing system is abbreviated as pressure relief opening and also called automatic pressure relief device.
Detailed introduction：
  
   Pressure relief opening of protective zone of gas fire extinguishing system is abbreviated as pressure relief opening and also called automatic pressure relief device. When pressure value within protective zone reaches the specified pressure value at the time of fire extinguishing agent of gas fire extinguishing system application, the device can automatically open decompression device to ensure safety and reliability of protective structure of building within protective zone and rapidly and timely fight the fire.
 
    The company successfully develops three types of pressure relief openings according to GB50370 and GB15930 national standards. The first type is outdoor wall-mounted gland-type without power supply; the second type is indoor embedded vane-type without power supply; the third type is indoor embedded type with power supply. Pressure relief opening of protective zone of gas fire extinguishing system is abbreviated as pressure relief opening and also called automatic pressure relief device.The product has the following features: (a) engaging pressure value of the product is real, accurate and reliable when the product is tested under the environment of simulating real environment, and this test model is the first application in China, which is the biggest feature of this product; (b) our company has the most complete product types, most integrated specifications and the most test reports in the industry of China, and the product which has achieved two appearance design patents and many utility model patents, is suitable for usage in all kinds of complicated protective zones;(c) structure of the first type has concise structure as well as original and beautiful shapes, and shapes of the second and third type are beautiful, upscale and luxury; (d) simple and convenient installation; (e) low price.

Notes: (1) Lag time of engaging-- refers to delayed engaging time of pressure relief opening when protective zone reaches set working pressure of engaging.
      (2) Pressure relief opening of protective zone of gas fire extinguishing system is abbreviated as pressure relief opening and also called automatic pressure relief device.Pressure relief opening of protective zone of gas fire extinguishing system is abbreviated as pressure relief opening and also called automatic pressure relief device. Pressure relief opening product does not match tuyere product. If the user needs tuyere product for matching, please put forward this requirement while ordering.
      (3)  Pressure relief opening of protective zone of gas fire extinguishing system is abbreviated as pressure relief opening and also called automatic pressure relief device.If order quantity of pressure relief opening is large, our company can also design and produce pressure relief opening according to the size of user’s pressure relief opening, but ordering cycle is rather long, because the process needs first making samples and then conducting relevant function tests, and after the test is eligible, then our company can officially manufacture products.
