Producdt Description
Fire breathing valve produced by our company has simplified structure, ventilation volume, less leakage, corrosion resistance, insulationetc.. The valve adopts polytetrafluoroethylene material, has the advantages of low temperature resistant, anti frost. The electrostaticprotection device is provided with a respiratory valve, the valve and the tank to keep the same potential moment.
Breatering manhole, fire breathing manhole is installed in the tank safety emergency ventilation device on the top, usually use and fire breathing valve supporting, not only can prevent accidental causes
Into the tank sharp overpressure or vacuum, damaged tanks and accidents, but also can play the role of fire safety, safety protection device is a tank, especially suitable for the storage materials to
The atmospheric tank nitrogen cap. With constant pressure discharge, the constant pressure suction, advantages of flexible open closed, safe fire retardant, compact structure, good sealing performance, safety and reliability etc..
Flame arrester is used to prevent flammable gas, liquid and prevent the spread of the flames caused by tempering safety device of explosion, widely used in petroleum and chemical industry etc.. Metal mesh in a flame arrester is mainly composed of many pores, these pores has heat dissipation function is very strong, when the flame through the mesh, the wall heat is very strong, each by a layer of metal mesh, the heat of the flame will continue to be a metal net absorption, when the heat comes to not make the combustible gas mixture combustion, the flame went out. After a period of time, the mesh is easy to plug, thus affecting the flame through, must always be clean, flame arrester structure of the traditional complex, disassembly and cleaning is time-consuming and laborious, for equipment maintenance inconvenience.
Aiming at the shortcomings of the existing fire resistance, the utility model provides a drawer type resistance model of fire breathing manhole.
A drawer type fire retardant breathing manhole, which comprises a valve body, the valve body is provided with a flange at the bottom of the valve body is provided with a flame arrester, middle, top is provided with a seat body, the pressure release cover installed in the seat at the top of the sliding positioning bracket, positioning bracket is provided with a guide screw and a positioning screw, screws with electrostatic conduction band, relief cap is provided with a breathing valve.
Flame arrester is composed of a metal net with holes.
The fire resistance material is stainless steel 304.
Electrostatic conduction materials for copper.
The utility model has the advantages of reasonable structure, convenient disassembly: cleaning, corrosion resistant, explosion-proof performance is strong, ventilation volume.

Producdt Description
In Line Flame Arrester is mainly composed of shell and fire element. There are two kinds of commonly used metal mesh filter element and corrugated filter element. The metal mesh filter element is composed of stainless steel or copper mesh with a diameter of 0.23-0.315 mm and overlapping layers. In Line Flame Arrester in China usually use 16-22 mesh metal mesh with 4-12 layers.
The corrugated filter element is supported by stainless steel, copper-nickel alloy, aluminium or aluminium alloy. Corrugated flame retardant can prevent the fierce flame of deflagration, and can withstand the corresponding mechanical and thermal effects, flow resistance is small, easy to clean and replace.

1, pipe flame arrester is a safety device in the process is suitable for transporting combustible gas, petrochemical, chemical, light industry and other industries. I plant the production of pipe flame arrester is carefully fire resistance design theory and precision special machinery and equipment manufacturing and into. According to the fire resistance and fire resistance rating can be divided into resistance deflagration and detonation resistance type two categories.
2, anti detonation flame arrester ZHQ-ZH high performance fire resistance, fire resistance in four layers of corrugated plate, structure design: the product consists of core and shell is composed of two parts, core component is the core, is composed of two layers of thin stainless steel belt, a pressure wave shape of N, another plane strip it tightly wrapped around the center of a circle. Thus a face, is a small triangle through the channel, and a support structure in the core cross internal (or in the surface pressure on the Y-shaped bracket) in order to enhance the reliability of the core member, to avoid explosion pressure dispersed generated core member lit medium. Medium from the triangle narrow canal by, flame arrester is through it to prevent fire in the pipeline of the spread, the principle is “wall effect”, is that the collision with the wall of the flame of energy conversion, lower temperature. This principle to design highly prevent flame triangular hole through, coupled with the channel length sufficient to absorb the heat of the flame, which extinguished in the core part, to avoid the possibility of gas is again at the other end of the core member.
