I. Product Overview
The ADGZJII-1 flame arrester is a safety device installed in the channels for conveying and discharging combustible gases, designed to prevent the spread of flames into the pipeline due to backfire. It is primarily composed of a flame arrester element, housing, gaskets, and connecting parts.
ADGZJII-1 explosion suppression fire extinguisher is cast, featuring a compact structure and easy disassembly.
Section 2: Working Principle
The core of the ADGZJII-1 explosion-suppressing fire arrester is a corrugated flame arrester plate, made of a stainless steel material with numerous small channels or gaps that allows gas to pass through. The requirement is for the gaps or channels in the corrugated flame arrester plate to be as small as possible. Therefore, when the flame enters the fire arrester, it is divided into many fine flame streams by the flame-retarding element. Due to the heat transfer effect (cooling of the gas) and the wall effect, the flame streams are extinguished.
Section 3: Gas Types and Flame arrester Clearance Refer to the Data Sheet
Section 4: Product Advantages
1. Provide professional fire arrester calculation sheets and CAD drawings based on the data tables and operating conditions provided by the customer.
2. Eddie has obtained the IIA fire damper certification and the patent certificate.
3. The flame arrester components are made of stainless steel corrugated flame arrester plates, featuring compact structure, high flow capacity, low pressure drop, and high reliability.
4. Carbon steel valve bodies are coated with anti-rust undercoat inside and out, with an epoxy topcoat applied externally; stainless steel valve bodies are sandblasted.
5. Packaging is uniformly done in standard wooden crates.
