The invention discloses a pneumatic actuator air tightness detecting device, which comprises an injection pipe, a connecting chute and an air tightness detecting device main body, and is characterized in that the connecting chute is installed at the upper end of the center of the air tightness detecting device main body, the rear end of an inner cavity of the connecting chute is provided with a sliding rail, the central end of the sliding rail is fixedly connected with a partition plate, the inner side of the sliding rail is slidably connected with sliding fixing blocks, two groups of sliding fixing blocks are symmetrically distributed through the partition plate, the lower end of the connecting chute is fixedly connected with a connecting platform, the lower end of the connecting platform is in telescopic connection with the injection pipe, the central end of an inner cavity of the injection pipe is provided with a water storage tank, the lower end of the water storage tank is communicated with a pressurizing valve, the lower end of the pressurizing valve is rotatably connected with a sliding rod, the lower end of the sliding rod is fixedly connected with a rotary frame, the central end of the rotary frame is clamped with an access port, and a communicating telescopic rod is inserted at the side end of the connecting chute. The pneumatic actuator air tightness detecting device can help to perform the air tightness detection work, and is simple and practical.
Description
technical field [0001] The invention relates to the technical field of air tightness detection, in particular to a device for detecting air tightness of a pneumatic actuator. Background technique [0002] The airtightness test is mainly to check whether there is any leakage at each connection part of the container. The pressure vessel whose medium is extremely toxic, highly hazardous, or the design does not allow a small amount of leakage must carry out the airtightness test. The airtightness test should be carried out at After the hydraulic test is qualified, the air tightness test can be carried out simultaneously with the air pressure test for the pressure vessel that is required by the design. [0003] One is that there is a phenomenon of leakage in the detection, which will cause inaccurate data, and the other is that there is a phenomenon that the plugging is not convenient enough, which needs to be improved. [0004] Utility model content [0005] The object of the ...
