One, main uses:

    Take over the respiratory valve is installed in the indoor fixed tank on top of the takeover of the fire breathing function, it can automatically adjust the pressure difference inside and outside the tank, its performance is reliable and stable, fully in line with the national standard GB5908-2004, suitable for storage of gasoline, kerosene, diesel, benzene, thick oil medium tank.

Two, product features:

    Take over the respiratory valve according to the structure is divided into: single pipe with exhale fire breathing valve with double over the fire breathing valve.

    First, take out one over the fire breathing valve is suitable for storage of flash point is lower than 28 ℃ the oil and flash point lower than 60 DEG C B oil storage tank, the same as gasoline, benzene, kerosene, light diesel oil, heavy oil and its properties.

    Second, with double over the fire breathing valve is suitable for storage of flash point is lower than 28 ℃ the oil and flash point lower than 100 DEG C B oil storage tank, the same as benzene, kerosene, light diesel oil, gasoline, heavy oil and its properties.

Three, ordering instructions:

    Firstly, products of the valve key part adopts polytetrafluoroethylene material. The use of positive and negative pressure valve, and at the same time can not be opened. Therefore, in the storage and transportation, the installation should avoid products will be inverted and the violent collision.

    Second, should be regularly carried out a clean dust and the examination of positive, negative valve sliding properties and the fire retardant core products. In order to ensure the normal breathing valve opens and the fire resistance performance.
