Description

Technical Field

[0001] The utility model relates to the technical field of airtightness detection of valve bodies, in particular to a detachable multi-valve body airtightness detection device. Background Technique

[0002] Valve bodies are mainly used for transporting gases and liquids. During their production and processing, to avoid leakage of valve bodies, it is necessary to detect their airtightness. Airtightness detection mainly refers to using a compressed air container and the pressure inside and outside the container for detection. The purpose of the detection is to check whether there is a gas leakage phenomenon.

[0003] In the prior art, Chinese Patent with the application number CN202322548712.4 discloses a detachable multi-valve body airtightness detection device. Its working principle is to place the valve body to be detected at the valve body placement seat. The electric turntable drives the valve body to rotate under the detection mounting frame. The first cylinder drives the first piston rod and the first plug to extend downward, so that the first plug plugs and seals one valve port of the valve body. The second cylinder is used to drive the second piston rod and the second plug to move downward to the valve body position. Through the downward extension force, the valve body is restricted and fixed to improve stability. The third cylinder is used to drive the third piston rod and the third plug to abut against another port of the valve body. The connecting pipe is pre-connected to the airtightness detection equipment. The airtightness detection equipment transports gas into the connecting pipe. The gas enters the plug and the valve body along the connecting pipe. According to the air pressure change in the valve body, it is used to detect whether there is leakage in the valve body. After the detection, the gas in the valve body is discharged, and the cylinder retracts upward and resets. The electric turntable rotates again, so that the valve body is moved to the subsequent detection position for multiple detections. Through the above structure, the valve body can be automatically detected, and can be detected multiple times, and can detect different ports according to the shape of the valve body, which is convenient for users.

[0004] In the above technical solution, although the valve body can be detected multiple times, it does not mark the defective products. That is, after the detection, it is easy to cause confusion when the defective products and the intact products are placed together and need to be detected and sorted again. For this reason, we propose a detachable multi-valve body airtightness detection device. Content of the Utility Model
