Description

TECHNICAL FIELD

[0002] Elastic element type pressure gauge is listed in the directory of national compulsory verification measuring instruments, and has huge verification demand. In the verification project, many metrological verification institutions use automatic verification device to improve the verification efficiency. The automatic verification device of the elastic element type pressure gauge adopts a camera shooting mode, reads the value of the pressure gauge pointer in the image through the related algorithm of image processing, and realizes the collection of verification data.

[0003] However, the automatic verification device still uses the traditional pressure gauge seat, that is, the pipeline of the mounting seat is vertically fixed on the automatic verification device, and the top is a threaded hole for fixing the pressure gauge. The traditional gauge seat has the following three problems: 1. The pressure gauge has two types of radial and axial, the traditional pressure gauge mounting seat is by default for the radial pressure gauge, and when the axial pressure gauge is verified, an adapter needs to be additionally installed to face the dial of the axial pressure gauge to the camera to complete the verification. When the radial pressure gauge and the axial pressure gauge appear alternately in the pressure gauge verification process, the adapter needs to be additionally disassembled and assembled, which is time-consuming and laborious, and affects the verification efficiency; 2. The axial pressure gauge verification through the adapter increases the number of pipeline connection points, increases the risk of pressure leakage, and also increases the difficulty of troubleshooting after pressure leakage; 3. The ordinary pressure gauge adapter cannot guarantee that the position of the dial of the axial pressure gauge relative to the camera is relatively unchanged compared with the radial pressure gauge, thereby affecting the reading of the dial value by the camera. For different models of automatic verification devices, corresponding adapters need to be customized, which are often larger in size and more difficult to install, and it is also difficult to find suitable replacement parts after loss.
