ZCZGB-II Drawer Type Flame Arrester

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.

Installation:

Remove all flange cover and discard all packaging materials.
Check the seat, the matching flange gasket on the seat surface. It must be clean, flat, scratch-free, corrosion-resistant, tool traces.
Check the gasket to ensure that the material is suitable forapplication.
Lubricate all studs and nuts with proper thread lubricant. If the fastener is a high temperature stainless steel material, a back-grabbing compound, such as molybdenum disulfide, is used.
Inside gasket of bolt ring.
Installing flange of Inline flame arrester shell to butt with flange of pipeline, attention should be paid to the position of lifting handle and top nut of In line flame arrester element to facilitate the removal of In line flame arrester elements in the future.

Producdt Description

ZCPE-pilot operated breather valve with flame arrester is a bit different with breather valve ,first let the seat leakage closer to set point ,second full flow without overpresure ,to maintain the tank pressure balance, reduce safety energy-saving products medium volatile, but also the use of principles of vapor heat transfer, protect the respiratory valve parts is not easy to freeze, the breathing valve to ensure the normal work, equipped with fire retardant explosion-proof function.

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.

Operating pressure:

Type A:	+355pa(+36mmH2O) -295pa(-30mmH2O)
Type B:	+980pa(+100mmH2O)-295pa(-30mmH2O)
Type C:	+1950pa(+200mmH2O) -295pa(-30mmH2O)
Type D:	according to user requirement (special pressure rating)

Summarize

Breathing valve is a kind of air breather which install on the petrochemical fixed storage tank, in order to avoid tank over the pressure or over vacuum making the storage tank destruct, prevent the outside flame enter ,reduce the tank fluid volatile.
According the countryGB50160 stipulate：“A,B kind fluid fixed arch-roof tank,should set arrester and breathing valve”.in order to meet the requirement,we develop and exploit all-weather（fire-proof）breathing valve whole series。Withing scientific and smart mould、completely specific-ation type、compact construction、light weight、huge breath capacity、small leakage etc features。The product construction have breathing type、single exhaust type、single suction type、reducing type、jacket type（detail information please reference HX series breathing valve).Every kind series can mount arrester, also can mount suc-tion、exhaust connection nozzle, also can manufacture any different material according to different medium such as petroleum、chemical、food industry,totally satisfy ev-ery kinds storage system process requirements.
