Therefore, the stability of the connecting handle after external adjustment is ensured.

Description

Technical Field

[0001] The utility model relates to the technical field of gas proportioners, and specifically relates to a dual-gas precision proportioner. Background Art

[0002] The dual-gas precision proportioner, also known as a gas proportioner, is a device used to precisely mix two gases. It is mainly used in industrial production, medical and health, food industry, experimental research and other fields to perform high-precision proportioning of two-component gases. Its precision and reliability are crucial for controlling the reaction process, ensuring product quality and the accuracy of experimental results.

[0003] In the existing dual-gas precision proportioner, the rotation at the bottom of the front-end flowmeter is inconvenient to lock after adjustment. Therefore, after being accidentally touched and misoperated by personnel, it will cause inaccurate proportioning of the dual gases. For this reason, we propose a dual-gas precision proportioner.
