[0020] like Figures 1 to 4As shown, a gas flow meter which is easy to disassemble and assemble comprises a butt joint tube 1, wherein the number of the butt joint tubes 1 is two, a measuring tube 2 is arranged between the two butt joint tubes 1, a flow meter body 3 is arranged on the surface of the measuring tube 2, a positioning assembly 4 for limiting the measuring tube 2 is arranged on the surface of the butt joint tube 1, filter blocks 5 are movably connected at both ends of the measuring tube 2, a quick-release assembly 6 for connecting the measuring tube 2 and the filter block 5 is arranged on the surface of the filter block 5, and a connecting flange 8 is fixedly connected to the end of the butt joint tube 1. More specifically, the butt joint 1 is connected to the gas pipeline through the cooperation of bolts and connecting flange 8, and the gas will flow through the butt joint 1 and the measuring tube 2. The gas flow can be monitored through the flow meter body 3. After using it for a period of time, the limit of the measuring tube 2 can be released through the positioning component 4, and the measuring tube 2 can be removed from between the two butt joints 1, so that the measuring tube 2 and the flow meter body 3 can be disassembled, and the measuring tube 2 and the flow meter body 3 can be inspected and maintained. The limit of the filter block 5 can be released through the quick-release component 6, and the filter block 5 can be disassembled, so that the filter block 5 can be cleaned or disassembled.

[0021] The positioning assembly 4 includes an installation box 401, and the installation box 401 is fixedly connected to the docking tube 1. The inner wall of the installation box 401 is rotatably connected to a double-headed screw 402, and the surface of the double-headed screw 402 is threadedly connected to a connecting rod 403. The end of the connecting rod 403 is fixedly connected to a positioning sleeve 405, and the inner wall of the positioning sleeve 405 is slidably connected to both the docking tube 1 and the measuring tube 2. A slide groove 404 is opened through the back of the installation box 401, and the inner wall of the slide groove 404 is slidably connected to the surface of the connecting rod 403. The positioning assembly 4 also includes an adjustment assembly for controlling the rotation of the double-headed screw 402. It should be noted that, by driving the double-headed screw 402 to rotate through the adjusting component, the connecting rod 403 will be driven to slide along the inner wall of the slide groove 404 under the action of the surface thread, thereby driving the positioning sleeve 405 to move along the surface of the butt joint 1, so that the positioning sleeve 405 is disconnected from the measuring tube 2, thereby releasing the limit on the measuring tube 2, and the measuring tube 2 can be removed from the end of the butt joint 1. In the specific implementation, the inner wall of the positioning sleeve 405 can be provided with a common sealing structure according to the needs, so as to seal the inside of the positioning sleeve 405 and prevent gas leakage from the positioning sleeve 405, which will not be elaborated here.

[0022] The adjustment assembly includes a worm 406, and the worm 406 is rotatably connected to the installation box 401, a knob 407 is fixedly connected to the front end of the worm 406, a worm wheel 408 is fixedly sleeved in the middle of the double-headed screw 402, and the surface of the worm wheel 408 is meshed with the worm 406. More specifically, by rotating the knob 407, the worm 406 is driven to rotate, thereby driving the worm wheel 408 meshed with it to rotate, and the double-headed screw 402 can be controlled to rotate.

[0023] The quick-release assembly 6 includes a mounting groove 601, and the mounting groove 601 is provided on the surface of the filter block 5. The inner wall of the mounting groove 601 is slidably connected with a shift block 602, and one side of the shift block 602 is fixedly connected with a plug post 603. The inner wall of the measuring tube 2 is provided with a concave hole, and the inner wall of the concave hole is movably plugged with the end of the plug post 603. A spring 604 is fixedly connected between the shift block 602 and the inner wall of the mounting groove 601. It should be noted that when the filter block 5 needs to be replaced or cleaned, the shift block 602 is pulled to overcome the elastic force of the spring 604, and the plug post 603 is pulled to move, so that the end of the plug post 603 is separated from the inner wall of the concave hole, and the limit of the filter block 5 can be released, so that the filter block 5 can be quickly disassembled.

[0024] There are two sets of quick-release components 6, and the two sets of quick-release components 6 are symmetrically arranged on the surface of the filter block 5. More specifically, by symmetrically arranging the two sets of quick-release components 6, the connection between the filter block 5 and the measuring tube 2 is more stable, and the filter block 5 is prevented from loosening.

[0025] Both ends of the measuring tube 2 are fixedly connected with sealing rings 7. It should be noted that by providing the sealing rings 7, the contact surface between the measuring tube 2 and the butt joint 1 is sealed, so that the two are in closer contact and gas leakage is avoided.

[0026] In summary: through the cooperation of bolts and connecting flange 8, the butt joint 1 is connected to the gas pipeline, the gas will flow through the butt joint 1 and the measuring tube 2, and the gas flow can be monitored through the flow meter body 3. After using it for a period of time, the limit of the measuring tube 2 can be released through the positioning component 4, and the measuring tube 2 can be removed from between the two butt joints 1, so that the measuring tube 2 and the flow meter body 3 can be disassembled, and the measuring tube 2 and the flow meter body 3 can be inspected and maintained. The limit of the filter block 5 can be released through the quick-release component 6, and the filter block 5 can be disassembled, so that the filter block 5 can be cleaned or disassembled, which realizes the effect of facilitating the quick disassembly and installation of the flow meter during use. Compared with traditional bolt fixing, disassembly and assembly is easier and more labor-saving, which effectively improves the disassembly and assembly efficiency, and makes the cleaning and maintenance of the flow meter more convenient.
