The ventilation and flame arresting device installed on the fixed top tank with a PTFE-lined tape taking over the flame arresting single breath valve can play a role in reducing oil evaporation loss, controlling the pressure balance of the storage tank and controlling the flame. It can automatically adjust the pressure inside and outside the storage tank. The valve is equipped with an electrostatic protection device, so that the valve keeps the same potential as the tank body at all times.
The single exhalation valve with takeover (fire resistance) is installed on the top of the storage tank. It is a device to discharge the positive pressure gas in the tank, so that the liquid output in the tank will not be hindered. When the external liquid is input into the tank, a large amount of gas is exhaled ( Called positive pressure). For example, when the work is stopped, the single exhalation valve with a take-over (fire-resistance) automatic closing will not leak the liquid gas in the tank, so that the quality of the liquid in the tank is guaranteed.
The single exhalation valve with takeover (fire-resistance) not only maintains the balance of the pressure of the storage tank, ensures that the storage tank is not damaged when overpressure, but also reduces the medium loss in the tank.
The valve seat with the takeover (fire resistance) single exhalation valve is a gravity structure. Its characteristic is that a soft contact with an air cushion is used between the valve disc and the valve seat, which has good air tightness and is not easy to freeze and is suitable for use in cold areas.
According to the national standard "Code for Fire Protection Design for Petrochemical Enterprises" (GB50160-92): "Fixed top tanks for storing Class A and Class B liquids should be equipped with flame arresters and breathing valves." The new type of single exhalation valve with takeover (fire resistance) is a safety device on fixed-top storage tanks such as crude oil, gasoline, kerosene, light diesel, aromatic hydrocarbons, etc. It is to prevent evaporation loss and protect the storage tank from damage when subjected to overpressure .
