[0002] Traditional valve leakage detection methods use kerosene leakage detection: under atmospheric pressure conditions, visually observe how many drops of kerosene leak per minute, rather than measuring under the actual working pressure of the valve. Therefore, the gas leakage volume cannot be accurately measured, and the kerosene leakage detection is inaccurate, making it impossible to detect and handle valve leakage in a timely manner, and thus polluting the workplace.

A branch is arranged on the pipeline between the flow sensor and the second stop valve; the valve detection platform includes a workbench surface, a cylinder body, a fixed disk, and a first chuck.

The upper end of the cylinder body is hermetically connected to the first chuck. The first chuck is hermetically clamped and matched with the lower end of the valve, and a valve pressing mechanism is arranged above the first chuck.
[0005] The valve pressing mechanism includes a second chuck and a number of pressure rods. The second chuck is clamped and matched with the upper end of the valve. The pressure rods are connected to the upper end of the second chuck and are provided with a pressing power source.

In this embodiment, refer to the attached Figures 1-4, the reciprocating compressor valve leakage detection system includes a compressed air cylinder group 1, a pipeline detection component 2 and a valve detection platform 3; the compressed air cylinder group 1 includes several air cylinders 11 connected in series, preferably 5 air cylinders 11, and the air cylinders 11 are filled with clean compressed air. A switch valve 12 is arranged at the outlet of each air cylinder 11 to provide compressed air to the detection system in real time; the pipeline detection component 2 includes a pipeline 21 and a pressure regulating valve 22, a check valve 23, a first stop valve 24, a thermometer 25, a pressure sensor 26, and a flow sensor 27 arranged on the pipeline 21 in sequence. One end of the pipeline 21 is connected to the compressed air cylinder group 1, and the other end of the pipeline 21 is an exhaust port 29. A second stop valve 28 is arranged at the exhaust port 29, and a shunt 20 is arranged on the pipeline 21 between the flow sensor 27 and the second stop valve 28; the valve detection platform 3 includes a workbench surface 31, a cylinder body 32, a fixed disk 33, and a first chuck 34. The fixed disk 33 is fixed on the workbench surface 31. Preferably, the fixed disk 33 and the workbench surface 31 are fastened by bolts and bolt holes. Corresponding air inlets 35 are arranged on the fixed disk 33 and the workbench surface 31, and the air inlets 35 are connected to the shunt 20. The lower end of the cylinder body 32 is sleeved on the fixed disk 33, and the lower end surface of the cylinder body 32 is hermetically connected to the workbench surface 31.

The pressure regulating valve 22 adjusts the pressure of the compressed air between 0.1 and 25 Mpa, and the pressure is displayed through the pressure sensor 26 to realize setting according to the actual working pressure of the valve. The flow sensor 27 detects the actual leakage amount of the valve.

Specifically, the compressed air enters the closed cavity formed by the cylinder body 32, the workbench surface 31, the fixed disk 33, the first chuck 34, and the valve 36 through the shunt 20.
