Abstract

The invention discloses a low-pressure testing table for oxygen bottle regulators. The low-pressure testing table comprises a gas source inlet X5, a vacuum source inlet X6 and an exhaust opening X7, wherein the gas source inlet X5 is connected with a first branch and a second branch, the output ends of the first branch and the second branch are separately provided with a tested component gas inletconnector X1 and a tested component gas inlet connector X2, the vacuum source inlet X6 is connected with a third branch, the output end of the third branch is provided with a tested component gas inlet connector X3, the exhaust opening X7 is connected with an output branch, the input end of the output branch is provided with a tested component gas outlet connector X4, the tested component gas inlet connector X1, the tested component gas inlet connector X2 and the tested component gas inlet connector X3 are separately connected with the gas inlet end of a tested component, and the tested component gas outlet connector X4 is connected with the gas outlet end of the tested component. The low-pressure testing table is a special testing table. Opening and closing control valves of the gas bottle regulators are independently regulated, flow and pressure on a gauze head on a shell panel are observed, and the performance test of all kinds of gas bottle regulators can be effectively finished.

Description

technical field [0001] The invention relates to the technical field of pressure and flow testing equipment, in particular to a low-pressure testing platform for an oxygen cylinder regulator. Background technique [0002] At present, regulators are widely used in gas delivery pipelines, and their main function is to adjust the higher upstream inlet pressure to a lower outlet pressure to ensure the stability of the downstream output pressure. Oxygen cylinders are usually used in medicine and chemical industry. The safety of the performance of oxygen cylinder regulators may not only affect the quality of gas delivery, but also directly affect the safety of life and industrial manufacturing. Therefore, the performance of oxygen pressure regulators needs to be checked before use. Special testing. In the prior art, the oxygen cylinder regulator mainly reduces the gas pressure to a safe range, but the performance and accuracy of the oxygen cylinder regulator lacks special testing ...
