Product Specification

Product Description

Application and principle of automatic explosion venting devices

The automatic explosion venting devices are safeguard to prevent flammable mediums causing equipment damage and fire. They can be used in systems of power generation, chemical, petroleum and heat supply. When explosion release, lightweight valve cover of the device opens quickly, drastically releases, eliminates secondary deflagrating phenomena, and automatically returns to original position after release and features precise reposition

Principle: When the pressure in the pipes exceeding the priming pressure that was set in explosion venting device, the device automatically opens and quickly releases the pressure, reaches the purpose of protecting equipment. After the pressure inside equipment maintaining in a state of equilibrium with the reposition pressure of automatic explosion venting devices, the device quickly returns to its original position, isolates the inside and outside air to prevent air return and avoid secondary deflagrating. 

Primary features: 

1. “UW airproof configurationIntegrated advantages of elasticity compensation, expansive seal, multi rings labyrinth seal, pressure energized seal etc., complex, compact structure, powerful function and easy maintenance. 

2. M valve cover and equalizer of valve cover: Reduced the possibility of jammed position, completely solved the problems like airproofdistortion, reposition and heat resistance, having the characteristics of light weight, high temperature resistance and anti-deformation

3. Detection signal: If automatic explosion venting device releases, it will give an alarm to the center control system (This case shows the system has problems that need to be checked up and solved); In case of the device doesnt close after releasing, related measures will be required by interlocking device. 

4. Buffer device of air pressureGreatly reduced impact inertia of moving parts, greatly improved the impact resistance of moving parts. It achieves gentle reposition. Compared with technical products of same types, it saves about 1/3 of space. And it is easy to choose the installation place. 

5. Modulation free reposition technology: Preventing system from secondary deflagrating, automatic reposition after releasing, preventing air return and avoid secondary deflagrating of system. 

6. Antirust treatment process: Including each surface of the product: Involves various methods like removing rust, painting, plastic sprayinggalvanization or plating nickel, use stainless steel etc. The process is applied to treat each surface that may be rusted, to insure the product is not only beautiful, but also has excellent performance after long time work. 

7. Anti-deformation: Each component of automatic explosion venting device was strengthened to ensure the device is not damaged in pressure relief

8. High temperature resistanceThe gasket ring (Si3C*5Al*0) between valve cover and flange can work at the temperature of **0℃ over a long period of time. With good seal performance and long service life, it can be repeatedly used. As it is an intertexture with good elasticity, it can reach the airproof effect of rubber, but doesnt age.
