In the crude oil gathering and transportation process, the storage tank is one of key equipment, and a breather valve, a hydraulic safety valve, a flame arrester and the like in the storage tank accessory are important components of the petroleum storage tank. According to the requirements of high-risk device facility storage tank accessory management and standard specification, the storage tank accessory management needs to be tested every year so as to ensure that the storage tank accessory management is in a normal working state in a test period. Currently, the breather valve structure is developed from the traditional split type gradually to the integrated type.
The respiratory valve of the arch-roof storage tank for Xinjiang is an all-weather respiratory valve and a common respiratory valve, and the lower part of the respiratory valve is provided with a flame arrester for the storage tank. The air temperature in the Xinjiang oil field is lower in winter, the lowest temperature can reach minus 40 ℃, vapor carried by a vapor medium in a storage tank in winter can generate polymerization, icing and adhesion between a metal corrugated steel strip tiny fire-retarding gap (generally 0.5 mm) of a fire arrester and a tiny gap between a valve core and a valve seat of a static seal of a breather valve and between the valve rod and a guide sleeve, so that the breather valve can not act and breathe, and potential safety hazards such as positive pressure overrun or negative pressure deflation of the storage tank are caused.
In order to ensure safe operation of the storage tank in winter, the conventional operating personnel often open the breather valve or open the storage tank, but the open operation of the storage tank can enable a large amount of oil gas volatile gas to be gathered at the tank opening, so that the operating personnel can generate ignition explosion risks in abnormal weather such as sampling operation or thunder, and the like, and simultaneously cause oil gas volatilization loss and environmental pollution.
By optimizing and analyzing the 'breathing-sucking' process, namely, when the storage tank works normally, the liquid level is converted into a stable process, and the storage tank comprises a purified oil tank, an aged oil tank and the like. The liquid level change is smaller when the storage tank is in normal operation, the storage tank respiratory conversion is also more stable, and the storage tank has longer conversion time from expiration to inspiration. When the liquid is fed into the storage tank, the breather valve is in an expiration state, and after the liquid feeding is finished, the breather valve is in a closed state for a certain period of time, so that the water drops in the fire-retarding gap of the flame arrester can be ensured to drop into the tank. When the storage tank discharges liquid, the breather valve is in an air suction state, and after the liquid discharge is finished, the storage tank stands for a period of time or immediately feeds liquid, and through the balanced 'breathing-sucking' process, the normal operation of the storage tank flame arrestor is ensured. Meanwhile, when a large number of storage tanks work normally, the liquid level operation is irregular, and the time is high and low, and the storage tanks comprise a crude oil buffer tank, a oil pulling tank, a dirty oil back mixing tank, a sewage buffer tank, a storage regulating tank and the like. The liquid level changes frequently when this kind of storage tank normal operating, and the storage tank exhales, breathes in the alternating frequency is more in the short time, and the water droplet that adheres to in the spark arrester fire relief gap when exhaling can not in time drip in the jar when breathing in, just relies on "breathe-inhale" balance adjustment to be difficult to reach the purpose of preventing frostbite, exists very big frozen stifled risk.
