Embodiment Construction
[0042] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. Generally, it is composed of a valve disc and a valve seat. The tightness between the valve disc and the valve seat directly affects the airtightness of the valve, and then affects the function of the valve. Surface defects on the sealing surface of the valve disc and the valve seat, such as scratches or pits, the more surface defects on the sealing surface of the valve disc and the valve seat, the worse the airtightness of the valve. In the actual working scene, the surface defects of the valve disc and the valve seat sealing surface are often detected by human visual inspection. The method of visual inspection is used to detect the valve, and its detection accuracy is poor. The valve detection system provided by this application aims to solve the above problems.

The invention relates to a valve detection system. The valve detection system comprises a control device, a scanning device and an image processing device, wherein the scanning device and the image processing device are arranged on the scanning control device; the control device, the scanning device and the image processing device are mutually connected; the control device is used for controllingthe movement state of the scanning device; the scanning device is used for obtaining scanning information of a target valve, and sending the scanning information to the image processing device; the scanning information comprises the information of the distances from all points on a valve sealing surface to a reference plane; the image processing device is used for generating a detection image of the target valve according to the scanning information. When the valve is detected, the scanning device is controlled by the control device to scan the target valve, the scanning information is obtained and processed through the image processing device, the detection image of the target valve is generated, and the valve detection result is obtained according to the detection image of the valve. Inthe valve detection process, the valve detection result is obtained through the valve detection system, and the valve detection precision is improved.
Description
technical field [0001] The invention relates to the technical field of scanning, in particular to a valve detection system. Background technique [0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. Generally, it is composed of a valve disc and a valve seat. The tightness between the valve disc and the valve seat directly affects the airtightness of the valve, and then affects the function of the valve. [0003] The airtightness of the valve depends on the surface defects of the sealing surface of the valve disc and the valve seat, such as scratches or pits. The more surface defects on the sealing surface of the valve disc and the valve seat, the worse the airtightness of the valve. In the actual working scene, the surface defects of the valve disc and the valve seat sealing surface are often detected by human visual inspection. [0004] However, with the above-mentioned method, the detection accuracy of the surface de...
