Instrument verification joint and pressure verification platform

Abstract

The invention relates to the technical field of instrument verification equipment, and discloses an instrument verification joint and a pressure verification platform, the instrument verification joint comprises a flange connection end (1) and a threaded connection end (2), the flange connection end can be connected with a flange structure of a diaphragm type pressure gauge (0), and the middle part of the flange connection end is provided with a through center hole (101); the threaded connection end is provided with a through hole (201) which penetrates in the axial direction of the threaded connection end and is communicated with the center hole, one end of the threaded connection end is connected with the flange connection end, and the other end of the threaded connection end can be connected with a threaded port of a pressure verification device. According to the invention, the problems that the connection port of the diaphragm type pressure gauge is of a flange structure, and the structure cannot be matched and connected with the threaded port of the existing detection device for verification, so that the diaphragm type pressure gauge is disposable from installation and use to scrapping, the production cost is high, and the requirements that the pressure gauge is regularly calibrated and cannot be calibrated cannot be met are solved.

Description

technical field [0001] The invention relates to the technical field of instrument calibration equipment, in particular to an instrument calibration joint and a pressure calibration platform. Background technique [0002] The production process of electrothermal chemical industry is complicated, and the medium components involved in the production are various, and most of them have the characteristics of high temperature, corrosiveness, flammability, explosion, and easy crystallization. In order to ensure relatively safe and long-term data collection and monitoring of the pressure of the pipelines conveying the above-mentioned media, diaphragm pressure gauges are usually selected. However, because the connection port of the diaphragm pressure gauge is a flange structure, this structure cannot be matched with the threaded port of the existing detection device for calibration, so that the diaphragm pressure gauge is disposable from installation to use until it is scrapped, and ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem in the prior art that the connection port of the diaphragm pressure gauge is a flange structure, which cannot be matched with the threaded port of the existing detection device for calibration, so that the diaphragm pressure gauge cannot be installed It is a one-time use until it is scrapped, which leads to high production costs and technical problems that cannot meet the requirements for regular verification and calibration of pressure gauges.
