Embodiment Construction

[0019] The invention replaces the traditional method of checking air tightness with soap bubbles, and adopts an air tightness checking device capable of measuring leakage to realize quantitative judgment on the air tightness of gas inlet valves.

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings, but it should not be used to limit the protection scope of the present invention.

[0021] Please see first figure 1 , which shows the tightness inspection device for the gas intake valve, including the compressed air connecting pipe 1 , the oil storage unit 2 and the intake valve connecting pipe 3 .

[0022] The oil storage unit 2 is a sealed container for containing lubricating oil; the inlet of the oil storage unit 2 is connected to the compressed air source through the compressed air connecting pipe 1, and the outlet is connected to the compressed air source through the inlet valve connecting pipe 3. The gas inle...

Abstract

According to the sealing performance inspection device and method for the fuel gas inlet valve, compressed air serves as a power source, lubricating oil in the sealing performance inspection device is pressed into the fuel gas inlet valve, and accurate quantitative judgment of the sealing performance of the fuel gas inlet valve is achieved by observing changes of the oil level of the lubricating oil in the sealing performance inspection device within preset time; the sealing inspection device comprises a compressed air connecting pipe, an oil storage unit and an air inlet valve connecting pipe, the oil storage unit is a sealing container and used for containing lubricating oil, an inlet of the oil storage unit is connected with a compressed air source through the compressed air connecting pipe, and an outlet of the oil storage unit is connected with a fuel gas inlet valve through the air inlet valve connecting pipe; and the oil storage unit is provided with scales used for marking the liquid level of internal lubricating oil. The device is convenient to operate, the sealing performance of the gas inlet valve can be quantitatively and accurately evaluated visually, the detection period and cost are reduced, and maintenance efficiency is improved.

Description

technical field [0001] The invention relates to the detection of components of a dual-fuel diesel engine, in particular to a sealing performance inspection device and method for a gas intake valve, and belongs to the technical field of marine diesel engine manufacturing. Background technique [0002] As a key component of a dual-fuel marine diesel engine, the gas intake valve's reliability and stability directly affect the performance and safety of the main engine. Among them, the sealing performance of the gas intake valve is the first among all performances. Keep completely sealed to avoid danger caused by gas leakage. The traditional sealing inspection method of the gas inlet valve is to smear soapy water around the sealing surface. After the gas inlet valve is pressurized, check whether there are soap bubbles around the sealing surface to judge whether the sealing is good or not. Although this method is intuitive, it cannot carry out long-term inspection and quantitativ...
