Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pressure gauges and relates to a pressure gauge component that can be assembled flexibly. Background Art
[0002] A pressure gauge is an instrument that uses elastic elements as sensitive elements to measure and indicate pressures higher than the ambient pressure. It is widely used in almost all industrial processes and scientific research fields. It can be seen everywhere in the fields of thermal pipelines, oil and gas transmission, water and gas supply systems, vehicle repair and maintenance shops, etc. Especially in the process of industrial process control and technical measurement, mechanical pressure gauges are increasingly widely used because of the high mechanical strength and easy production of the elastic sensitive elements of mechanical pressure gauges. In actual use, due to the limited environmental space to be tested, the pressure gauge cannot be effectively assembled on the equipment, thus failing to meet the test requirements. At the same time, liquid is likely to remain in the pressure gauge assembly after the test. In order to test other equipment later, it is necessary to perform multilateral cleaning to place liquid residues, which reacts with other subsequent liquids, thereby affecting the subsequent test results and even causing damage to the pressure gauge assembly.
