Abstract

The invention relates to the field of thermal flow meters, in particular to a thermal fluid flow meter which comprises a connecting pipeline body, a first sleeve, a second sleeve, a third sleeve, an outer sleeve and a flow meter head. A sealing air bag and a positioning block are arranged, the sealing air bag is fixedly connected to an inserting rod in a sleeving mode, the sealing air bag is inserted into an outer sleeve along a preset groove of the outer sleeve through a positioning sliding block along with the inserting rod in an uninflated state, and the inserting rod is rotated after a telescopic sliding block and a salary groove of the outer sleeve are mutually positioned; in the rotating process, it should be noticed that a limiting rod is inserted into a limiting groove of the positioning block at the same time, the limiting rod is successfully inserted through magnetic attraction force between a magnetic block in the limiting rod and the positioning block, and then the limiting rod and the outer sleeve are locked. A proper amount of gas is inflated into the sealing air bag through the inflation nozzle, so that the sealing air bag is expanded, the sealing state is further achieved, the inserting rod is convenient to disassemble, assemble and overhaul, and meanwhile good air tightness is guaranteed.

Description

technical field [0001] The invention relates to the field of thermal flowmeters, in particular to a thermal fluid flowmeter. Background technique [0002] The thermal flowmeter adopts the principle of thermal diffusion, and thermal diffusion technology is a technology with excellent performance and high reliability under harsh conditions. Thermal flowmeters have two temperature sensors placed in the medium, one of which is heated to a temperature above the ambient temperature, and the other temperature sensor is used to sense the temperature of the medium. As the flow rate of the medium increases, the heat taken away by the medium increases, and the temperature difference between the two temperature sensors will change with the flow rate of the medium. According to the proportional relationship between the temperature difference and the flow rate of the medium, the flow rate Q of the fluid can be obtained. [0003] The existing thermal fluid flowmeters mainly have the follo...
