Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas removal, in particular to a gas removal device for pressure pipeline. BACKGROUND

[0002] The pressure pipeline refers to a closed pipeline system specially used for conveying liquid or gas with certain pressure, and its core feature is that the fluid pressure inside the pipeline is higher than the external environment pressure, so it needs to meet specific strength, sealing and safety standards. When the existing pressure pipeline is used to convey fuel oil, water or edible oil on the fuel oil test bench or other types of test bench, it is possible that gas will be generated in the liquid due to the dissolution of the liquid itself, leakage from the outside, residual un-drained or chemical reaction, etc. In order to avoid the influence of this gas on the components of the hydraulic system and test data, a gas removal device is installed on the pressure pipeline to remove the gas in the liquid during the flow of the liquid in the pressure pipeline, and this gas removal device installed on the pressure pipeline can be called a gas removal device for pressure pipeline.

[0003] However, in the structure of the gas removal device widely used in the hydraulic pipeline of the existing fuel oil test bench, when the floating ball in the pipeline moves upward due to pressure, it may block the exhaust port, thereby failing to effectively remove the gas in the pipeline. In addition, the separated gas in the existing gas removal device directly contacts the fuel oil, and as the fuel oil flows in the gas removal device, a part of the separated gas will be re-entrained into the interior of the fuel oil, thereby affecting the overall gas-liquid separation effect of the equipment. In the existing gas removal device, the internal liquid level rises and falls to control the upward and downward movement of the floating ball device, thereby opening and closing the exhaust port. Through this structure, only a small amount of gas can be removed at a time, and when a certain amount of gas is removed, the floating ball will move upward together with the rising liquid level, and the exhaust port will be automatically sealed again. The single gas removal capacity of this structure is small, the use frequency of the exhaust port sealing structure on the equipment is high during the operation of the equipment, the wear speed is fast, and the service life of the equipment is short. Therefore, it does not meet the existing needs, and thus we propose a gas removal device for pressure pipeline. SUMMARY

The above technical solution improves the gas-liquid separation effect of the equipment. 3. After the exhaust head is pulled downward by the gas-liquid pushing isolation plate to open the exhaust port, the anti-wear mechanism of the exhaust head can fix the exhaust head pulled downward at the current position during the exhaust process. The above technical solution can prevent the exhaust head from moving upward together with the gas-liquid pushing isolation plate after a small amount of gas is discharged, thereby preventing the exhaust port from being sealed again.
