High-precision combustible gas mixer

Abstract

Belonging to the technical field of combustible gas mixing, the invention particularly relates to a high-precision combustible gas mixer. The high-precision combustible gas mixer comprises a support seat, a mixing tank is fixedly mounted at the top of the support seat, a first threaded rod is rotatably mounted in the mixing tank, a speed reducing motor is fixedly mounted on one side of the mixingtank, one end of the first threaded rod extends out of the mixing tank and is fixedly connected to an output shaft of the speed reducing motor, a piston is slidably and airtightly installed in the mixing tank, the piston is in threaded connection with the first threaded rod, a sliding rod is fixedly installed in the mixing tank, and the sliding rod runs through the piston and is slidably and airtightly connected to the piston. The high-precision combustible gas mixer provided by the invention is easy to operate, high in practicability and adjustable in volume, can guarantee the mixing efficiency and precision in mixing gas of any volume, at the same time can change the pressure and flow of different raw material gases during entering, can balance the pressure difference when different rawmaterial gases enter, and improves the mixing precision.

Description

technical field [0001] The invention relates to the technical field of combustible gas mixing, in particular to a high-precision combustible gas mixer. Background technique [0002] Gas mixing is to mix different gases in proportion. Combustible gases need to be mixed during production. The gas composition is precisely controlled. After searching, the patent document with the authorized announcement number CN108043323A discloses a small high-precision gas proportioner. Although the gas proportioning valve is used to directly control the gas mixing ratio, and the pressure complementary regulator is used, Make the multi-channel gas pressure used for proportioning compensate each other, keep the pressure consistent and enter the gas proportioning valve. This scheme abandons the flow test method, directly controls the gas mixing ratio, and has no pipeline design, which effectively solves the problems of pipeline layout, leakage and inconvenient maintenance.

Problems solved by technology

[0003] However, in the above technology, the mixing volume cannot be adjusted. When mixing a small amount of combustible gas, the mixing accuracy is low. At the same time, it is not convenient to adjust the pressure and flow of the intake air. Therefore, a high-precision combustible gas mixer is proposed.
