High voltage explosion-proof flame arresterModel:GNG-2

High voltage explosion-proof flame arresters generally use stainless steel as the valve body and flame retardant layer material, forged and manufactured, resistant to high temperature and high pressure, and can be used when flames pass through narrow pores of thermal conductors,The principle of extinguishing due to heat loss

Design and manufacture devices to prevent the spread of flames. Widely used in combustible gas pipelines, such as gasoline, kerosene, light diesel, benzene, toluene, crude oil and other oil storage or flare systems, gas purification and chemical systems

Integrated gas analysis system, coal mine gas emission system, heating furnace fuel gas pipeline network, and can also be used as pipeline supplies for acetylene, oxygen, nitrogen, and natural gas.High voltage explosion-proof flame arresterMainly composed of the shell

It consists of two parts: the filter element. The shell should have sufficient strength to withstand the impact pressure of an explosion. The filter element is the primary component that obstructs the spread of flames, and commonly used ones include metal mesh filters and corrugated filters

Seed. Diameter for metal mesh filter element0.23~0.315mmStainless steel or copper mesh, composed of multiple layers of overlapping. At present, flame arresters in China are generally selected16~22Metal mesh, for4~12Layer. Flame arresters are generally

Installed on the main fuel gas pipeline in front of the furnace, it is usually a short pipe with a diameter thicker than the fuel gas pipeline and flanges at both ends. Ten pieces of copper wire mesh are installed perpendicular to the airflow inside the pipe, usually with a certain thickness

The cast aluminum ring of the degree compresses the periphery of the mesh and forms a certain distance. Due to the excellent heat dissipation performance of copper mesh, when the flame encounters the copper mesh, it will extinguish due to a sharp drop in temperature, thus achieving a flame retardant effect.

High voltage explosion-proof flame arresterInstallation and maintenance:

1、 In order to ensure the performance of the flame arrester meets its intended use, it is necessary to carefully read the instructions provided by the manufacturer before installing the flame arrester, and carefully check whether the label is consistent with the requirements of the installed pipeline.

2、 The flow direction mark on the flame arrester must be consistent with the flow direction of the medium.

3、 It should be checked every six months. Check whether the fire-resistant layer has defects such as blockage, deformation, or corrosion.

4、 The blocked fire-resistant layer should be cleaned thoroughly to ensure that each hole is unobstructed, and any deformed or corroded fire-resistant layer should be replaced.

5When cleaning the flame arrester core components, high-pressure steam, non corrosive solvents, or compressed air should be used for blowing, and sharp hardware brushes should not be used.

6、 When reinstalling the flame retardant layer, the gasket should be updated and the sealing surface should be confirmed to be clean and undamaged, without any air leakage
