[0002] The multi-way valve is an important component in crude oil extraction equipment. The multi-way valve has multiple oil ports, all of which are connected to pipelines for transporting oil. During production, the roughness of the edge of the valve core in the multi-way valve needs to be detected to avoid oil leakage in the multi-way valve. For example, the patent document with application number CN202320062508.9 discloses a smoothness detection device for automobile parts. By setting an automatic clamping device, the first telescopic rod drives the clamping block to clamp the parts of the material transport slide, thereby avoiding the loosening of the automatic detection body during detection and affecting the data.

[0003] However, in the above-mentioned similar schemes, during the production process of the existing multi-way valve, the smoothness of the inner side of the multi-way valve is detected by human eyes, but the light inside the multi-way valve is weak, resulting in low accuracy. In addition, since a group of multi-way valves is provided with multiple groups of valve cores on the inside, multiple inspections are required, and each inspection can only check one group of valve cores, resulting in slow inspection.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a sealing component smoothness detection device is proposed. Utility Model Content

[0012] The utility model provides a sealing component smoothness detection device, which has the following beneficial effects:

[0013] It can be realized that during the production process of the multi-way valve, the roughness of the inner wall of the multi-way valve can be automatically detected by the infrared detection head, avoiding human eye detection, which is conducive to improving the accuracy of detection. In addition, it can detect multiple groups of valve core outer walls at the same time, thereby avoiding the need for multiple detections, which is conducive to saving detection time and manpower.

[0022] The adjusting component 6 is located at the outer side of the fixing seat 504, and the adjusting component 6 includes a support plate 601, a fixing ring 602, a limit block 603 and a fixing pin 604. The outer side of the support rod 4 is slidably connected with two groups of fixing rings 602, which can freely adjust the height of the detection component 5, which is beneficial to improving the practicality of the device.
