Fire breathing valve produced by our company has simplified structure, ventilation volume, less leakage, corrosion resistance, insulation, etc.
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.
under normal circumstances, (fire) breathing valve operating pressure to B shall prevail;

1. storage: the above products should be stored in a warehouse with rain protection facilities if they are not installed for the time being or overhauled and overhauled by the factory after they are delivered to the construction site; the breathing valve series products shall not be inverted when transported.
a.For respiratory valve series products, staff should check the top of the tank once a month to check the disc, seat, stem, valve sleeve and other parts of dust, dirt, if so, should clean dry and quiet; every six months, wipe the valve sleeve, valve stem wipe transformer oil.
b.The staff of the semi-annual staff shall check the fire-blocking layer of the fire-resistant breather valve. If there is a stain and the impurity is blocked from the fire-blocking layer, the lower fire-blocking layer shall be removed, the stain shall be removed by the corresponding solvent, and the fire-retardant layer shall be cleaned and dried with clear water, and then put into the casing after the ventilation and blow-drying.
c.The paint on the inner and outer surfaces of the above products should be repainted once a year.
