Problems solved by technology
[0005] The small hole on the liquid level measurement guide pipe causes the oil and gas in the pipe to volatilize between the top of the storage tank and the inner floating roof, and then discharge to the atmosphere through the breather valve on the top of the tank, which not only causes oil and gas loss, but also affects the safe operation of the storage tank
According to the "Oil Meter Reader (Third Edition)" by Sinopec Press, in the internal floating roof gasoline storage tank, the distance is 0.5m and the pore area is 1cm 2 A pair of small liquid level holes, the oil and gas discharged every day and night can reach 12kg, so it is estimated that the loss caused by the many liquid level small holes set on the liquid level measurement guide pipe is very large

The invention discloses an automatic hole sealing device for an inner floating roof storage tank liquid level measurement guide pipe and belongs to the field of petrochemical product storing systems. The automatic hole sealing device is installed in the inner floating roof storage tank liquid level measurement guide pipe and at least comprises a front plate, a rear cover and a hole sealing device floater. The front plate is provided with a front plate hole. The rear cover is provided with at least one rear cover hole. The front plate and the rear cover are connected to form a box type, and the hole sealing device floater is arranged in the box. By utilizing the buoyancy of liquid and the gravity of the hole sealing device floater, the hole sealing device floater can automatically open or close the front plate hole. The automatic hole sealing device can achieve exchange of the liquid inside and outside the liquid level measurement guide pipe and the liquid level balance, and has the function of blocking small liquid level holes of the liquid level measurement guide pipe; the problem that oil gas is exhausted through the small liquid level holes of the liquid level measurement guide pipe and exhausted to atmosphere through a tank top breather valve can be solved, and oil gas loss caused by the small liquid level holes of the liquid level measurement guide pipe can be effectively reduced.
Description
technical field [0001] The invention relates to the field of storage systems for petrochemical products, in particular to an automatic hole sealing device for liquid level measurement guide pipes of inner floating roof storage tanks. Background technique [0002] The inner floating roof storage tank is formed by adding a floating roof inside the storage tank with a vault. Dust, etc. enter the tank to ensure that the medium in the tank is clean. Internal floating roof storage tanks are mainly used to store light oil, such as gasoline, aviation kerosene, etc. There is a liquid level measuring guide tube in the inner floating roof tank, which runs through the floating plate from the top of the tank to the bottom of the tank, and the oil surface can be seen directly from the liquid level measuring guide tube. [0003] The liquid level measurement guide pipe is the main part of the liquid level measurement device of the inner floating roof storage tank. A pair of symmetrical l...
