[0028] Please refer to Figures 1-4, the present utility model provides a technical solution:

[0029] A gas turbine flowmeter for gas includes a pipeline 1 and a display 2. An installation box 3 is fixedly connected to the upper part of the outer surface of the pipeline 1. A limiting mechanism 4 is inserted and connected to the left end of the installation box 3. An installation groove 5 is opened at the upper end of the installation box 3. A through slot 6 is opened on the left slot wall of the installation groove 5. A trapezoidal clamping block 7 is fixedly connected to the right slot wall of the installation groove 5. An installation block 8 is fixedly installed at the lower end of the display 2. A limiting slot 9 is opened at the left end of the installation block 8. A trapezoidal clamping groove 10 is opened at the lower part of the right end of the installation block 8. A sealing ring 11 is fixedly connected to the lower end of the installation block 8.

[0030] In this embodiment, the limiting mechanism 4 includes a connecting strip 41. A spring 42 is fixedly connected to the middle of the right end of the connecting strip 41. A limiting block 43 is fixedly connected to the right end of the spring 42. A connecting rod 44 is fixedly connected to the middle of the left end of the limiting block 43. A pull ring 45 is fixedly connected to the left end of the connecting rod 44. Fixing rods 46 are fixedly connected to both the front part and the rear part of the right end of the connecting strip 41. The spring 42 is located outside the connecting rod 44. The limiting block 43 is inserted and connected to the through slot 6, and the end of the limiting block 43 away from the connecting rod 44 is clamped and connected to the limiting slot 9. The connecting rod 44 is inserted and movably connected to the connecting strip 41. The right ends of both fixing rods 46 are fixedly connected to the installation box 3.

[0031] Through the above solution: By pulling the pull ring 45 to the left, the pull ring 45 drives the limiting block 43 to move to the left through the connecting rod 44, compressing the spring 42, and at the same time leaving a space in the installation groove 5. Then, the installation block 8 below the display 2 is seamlessly clamped into the installation groove 5 above the installation box 3, so that the sensor below the display 2 passes through the installation box 3 and enters the pipeline 1. When the installation block 8 is completely embedded, release the pull ring 45, and under the elastic reset of the spring 42, the limiting block 43 is inserted into the limiting slot 9 on the left side of the installation block 8, so that the display 2 is convenient and quick to install, improving the installation efficiency, without the need to use complex tools and cumbersome installation steps, and facilitating the subsequent quick disassembly, maintenance or replacement of the display 2.

[0032] In this embodiment, the installation block 8 is seamlessly clamped and connected to the installation groove 5. The horizontal positions of the limiting slot 9 and the through slot 6 correspond to each other. The trapezoidal clamping groove 10 is clamped and connected to the trapezoidal clamping block 7. The lower end of the sealing ring 11 is closely attached to the lower slot wall of the installation groove 5. The sensor below the display 2 penetrates the installation box 3 and extends into the pipeline 1.

[0033] Through the above solution: During the installation of the display 2, when the installation block 8 is seamlessly inserted into the installation groove 5, the trapezoidal card slot 10 on the right side of the lower end of the installation block 8 is seamlessly clamped with the trapezoidal card block 7 in the right part of the installation groove 5, making the connection between the two closer, improving the reliability of the connection, and the sealing ring 11 under the installation block 8 is closely attached to the lower groove wall of the installation groove 5, strengthening the connection tightness between the two.

[0034] It should be noted that the present utility model is a gas turbine flowmeter for gas use. During use, by pulling the pull ring 45 towards the left, this action drives the connecting rod 44 to drive the limit block 43 to move synchronously to the left. During this process, the spring 42 is compressed and stores potential energy. This operation aims to create space in the installation groove 5 to facilitate the seamless docking of the installation block 8 at the bottom of the display 2 into the installation groove 5 at the top of the installation box 3. This process ensures that the sensor under the display 2 can smoothly pass through the installation box 3 and finally be positioned inside the pipeline 1. Once the installation block 8 is completely inserted into the installation groove 5, release the pull ring 45, and the spring 42 immediately uses the stored elastic force to push the limit block 43 back to its original position, enabling it to accurately fit into the preset limit groove 9 on the left side of the installation block 8, thus realizing the rapid and stable installation of the display 2. During the docking process of the installation block 8 and the installation groove 5, the trapezoidal card slot 10 on the right side of the lower edge of the installation block 8 is seamlessly clamped with the trapezoidal card block 7 on the right inner wall of the installation groove 5, significantly enhancing the connection tightness and stability between the two. At the same time, the sealing ring 11 equipped at the bottom of the installation block 8 is closely attached to the lower groove wall of the installation groove 5, further improving the sealing performance of the connection and preventing gas leakage. In summary, this gas turbine flowmeter improves the installation efficiency of the display 2, eliminates the use of complex tools and cumbersome installation steps, and provides great convenience for the subsequent rapid disassembly, maintenance, or replacement of the display 2.
