Product Introduction
· Product use
In the pulverizing system of thermal power plant, due to the inherent characteristics of pulverized coal
It is very easy to explode, which seriously affects the safety of equipment
Reliable operation. Therefore, it is necessary to install explosion-proof doors in the pulverizing system
Use this device to release the pressure generated by the explosion to protect the device
Or parts are protected from damage.
· Product introduction
Gt-avid series self-opening and closing explosion-proof door is a new generation system developed by Lianyungang Huadong Electric Power Equipment Co., LTD
List of automatic detonation products. The device adopts magnetic automatic opening and closing technology, has the characteristics of accurate opening pressure, high blasting efficiency, automatic resetting after detonation, no need to stop, and preventing secondary deflation of the system. Tested by the Safety Engineering Research Center, all indicators fully meet the NFPA68/69 standard. It is a substitute product for traditional diaphragm explosion-proof door and gravity explosion-proof door.
· Structural characteristics
1. Cylindrical shape structure to ensure the strength of the fixed bracket.
2. Guide rails are adopted to ensure the flexibility of the door cover.
3. The door cover is made of special ultra-light and high-strength material to ensure high blasting efficiency.
4. The reset spring adopts the external displacement mode, and does not contact with the door cover with higher temperature to ensure that the spring does not fail.
5. The high temperature explosion-proof door is sealed with stainless steel graphite to ensure the tightness of the explosion-proof door.
· Product features
1. The detonation pressure is accurate and can be adjusted in the test bench and on site.
2. High blasting efficiency ≥90%, which is 6~10 times that of gravity type.
3. Automatic reset, automatic return after explosion-proof door explosion, no need to stop, increase the unit equivalent availability factor.
· Other Features
1. Use special test tools: Set the rated operating pressure according to the requirements, and can use special test tools to achieve test and adjustment on the test bench or field.
2. Fireproof net: Fireproof net can be added. The fireproof net is composed of high thermal conductivity material, which is used to block or buffer the flame from the container, prevent the fire caused by the flame ejecting during the explosion, and protect the operator from the hot air burn.
