Abstract

The invention relates to a tool for a pressurization test of a pressure transmitter. The tool comprises a bottom plate, a pressurization rod assembly, a supporting assembly and a limiting assembly. In the actual use process, the pressurization rod assembly and the supporting assembly are assembled in advance, when a pressurization test needs to be conducted on the pressure transmitter, a user aligns the bottom of the pressure transmitter to the upper portion of the pressurization rod assembly and vertically inserts the pressure transmitter into the pressurization rod assembly till the pressure transmitter makes contact with the supporting assembly, and then the limiting assembly is moved to the position above the pressure transmitter and is connected with the supporting assembly, then a pressure source is connected into the main pressurization hole, the pressure source flows into the branch pressurization holes and is guided into the pressure transmitter through the pressurization rod assembly for pressure testing, and therefore threaded fastening and sealing are not needed, operation is easy, labor intensity is low, the tool can be quickly assembled and disassembled, is large in adaptive pressure range, and can be better used for automatic testing of a production line.

Description

technical field [0001] The invention relates to the technical field of pressure transmitter testing, in particular to a tool for pressurization testing of pressure transmitters. Background technique [0002] A pressure transmitter is a device that converts pressure into a pneumatic signal or an electric signal for control and remote transmission; it can convert physical pressure parameters such as gas and liquid felt by the load cell sensor into a standard electrical signal for supply Indicates secondary instruments such as alarms, recorders, and regulators for measurement, indication, and process adjustment. [0003] At present, pressure transmitters are mostly sealed in the form of screw fastening when performing pressure tests, which is cumbersome to operate and labor-intensive, and cannot be used for automatic testing in production lines, resulting in low efficiency and dependence on personnel more sexual. [0004] In order to improve the efficiency of the pressurizati...
