There are many varieties of fire breathing valve, each with its different performance and characteristics, in the selection of the characteristics of the conditions to meet, fire arrestor whether to achieve the best operating effect, and then consider some objective factors. Dual nozzle fire retardant breathing valve is one of the popular products in the market. The double nozzle fire blocking breather valve plays a safety protection role in the system. In practical application, its characteristic type should be selected according to actual needs, and its diameter should be selected as the best scheme according to the maximum exhaust volume.
The double nozzle fire retardant breathing valve is suitable for storage of Class A oil with internal point less than 28C and ethyl oil with flash point less than 100C, such as gasoline benzene, kerosene, light diesel oil, thick oil and other oil products and chemical products with the same nature.Gas flame arrester inline fire arrestor Its function is installed on the top of the indoor fixed storage tank nozzle fire resistance breathing, it can automatically adjust the oil storage tank internal and external pressure difference, its performance is reliable, stable, fully in line with the Ministry of petroleum industry SY7511-87 standard. In order to ensure that the performance of the double nozzle fire stop breather valve reaches the maximum effectiveness and can be used safely and continuously, the fire stop breather valve should be inspected and maintained regularly: when reinstalling the pressure disc and the vacuum disc, the contact surface should be tight and the guide rod should be lifted and lifted flexibly; When the new breathing valve is started, the shock absorber must be removed from the disk; Check whether the pressure valve disc and vacuum valve disc are flexible, and whether the guide rod and the contact surface of the valve seal ring are damaged.
