DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0024] REFERENCE Figures 1-2 An embodiment provided by the utility model: a disassembly-free pressure measurement interface, comprising a pressure valve 1, the pressure valve 1 side wall is fixedly connected with connecting pipe 2, and the connecting pipe 2 side wall is provided with a holding assembly, and the pressure valve 1 side wall is provided with a connecting assembly;

[0025] The holding assembly comprises a side frame 3 fixedly connected to the side wall of the connecting pipe 2, a pushing table 4 slidingly connected to the side wall of the side frame 3, a pushing frame 5 arranged at the top of the pushing table 4, a plurality of springs 6 arranged between the pushing table 4 and the pushing frame 5, one end of each spring 6 fixedly connected to the inside of the pushing table 4, the other end of each spring 6 fixedly connected to the inside of the pushing frame 5, a plurality of sliding shafts 7 fixedly connected to the inside of the pushing frame 5, a plurality of rotating tables 8 rotatably connected to the side wall of the side frame 3, and a hoop 9 rotatably connected to the inside of each rotating table 8.

[0026] Specifically, when the metering device needs to be fixed to the pipeline, the operator pushes the pushing table 4, and the pushing table 4, by virtue of its structural characteristics, synchronously pushes the pushing frame 5 connected to the top of the pushing table 4. The pushing frame 5 moves in the vertical direction along the side wall of the side frame 3 under the action of the force. In this process, the plurality of sliding shafts 7 arranged in the pushing frame 5 rotate in the plurality of rotating tables 8 corresponding to the sliding shafts 7. The sliding shafts 7 apply a pushing force to the rotating tables 8 when the sliding shafts 7 rotate, so as to make the rotating tables 8 rotate around a point on the side wall of the side frame 3 and change the inclination angle of the rotating tables 8. With the change of the inclination angle of the rotating tables 8, the hoop 9 connected to the rotating tables 8 moves correspondingly to hold the pipeline tightly. This fixing method can realize rapid installation and positioning without complicated disassembly process. In this way, the operator can quickly complete the connection and replacement of the pressure measuring equipment, significantly improving the work efficiency and reducing the time loss caused by equipment installation or replacement.

[0027] Reference Figure 3 The connecting assembly comprises a measuring channel 10 fixedly connected to the side wall of the pressure valve 1, an inner connecting pipe 2 slidingly connected to the inside of the measuring channel 10, an inner connecting pipe 1 fixedly connected to the inside of the measuring channel 10, an outer connecting ring 13 fixedly connected to the outer wall of the inner connecting pipe 2, a sleeve ring 14 slidingly connected to the outer wall of the measuring channel 10, an inner groove 15 arranged in the measuring channel 10 and the sleeve ring 14, a plurality of clamping beads 16 slidingly connected to the inside of the inner groove 15, a clamping groove 17 arranged in the inside of the sleeve ring 14, a spring 18 sleeved on the outer wall of the inner connecting pipe 1, one end of the spring 18 fixedly connected to the inside of the sleeve ring 14, and the other end of the spring 18 fixedly connected to the outer wall of the measuring channel 10.

[0028] Specifically, when the inner tube 12 for a specific measurement environment needs to be maintained and disassembled, the maintenance personnel manually pull the sleeve ring 14, and the sleeve ring 14 smoothly slides along the outer wall of the measurement channel 10 after being subjected to the pulling force. In the process, the movement of the sleeve ring 14 will squeeze the second spring 18 located at the tail of the sleeve ring 14. With the sliding of the sleeve ring 14, the pre-set inner groove 15 inside the sleeve ring 14 will gradually align and coincide with the inner groove 15 inside the measurement channel 10. At this time, the snap bead 16 is provided with a slidable space. In the process of pulling out the inner tube 12, the snap bead 16 no longer plays a clamping limiting role on the outer connecting ring 13, but is pushed into the inner groove 15. Such a design realizes the quick disassembly of the inner tube 12. After the disassembly operation is completed, the sleeve ring 14 can be reset to the initial position by the elastic force of the second spring 18. When the measurement pipeline has common problems such as blockage, leakage or corrosion, the convenient disassembly method can quickly disassemble the inner tube 12 by the maintenance personnel, so as to quickly locate and solve the problem. Without spending a lot of time dealing with complex disassembly procedures, the maintenance time is effectively shortened, thereby reducing the economic loss caused by the shutdown of the equipment.

[0029] Working principle: First, when the metering device needs to be fixed on the pipeline, the push table 4 is pushed, and the push table 4 will synchronously push the push frame 5 at the top after being subjected to the force, so that the push frame 5 can vertically displace on the side wall of the side frame 3. At this time, the plurality of slide shafts 7 inside the push frame 5 can rotate in the plurality of rotating tables 8 and push the rotating tables 8, so that the rotating tables 8 rotate on the side wall of the side frame 3 and change the inclination angle thereof. Subsequently, the angle change of the rotating tables 8 can drive the hoop 9 to tightly hold the pipeline, so that the pressure measurement equipment can be quickly connected and replaced without complex disassembly procedures. The operator can quickly complete the connection and replacement of the pressure measurement equipment, which significantly improves the work efficiency. When the inner tube 12 needs to be maintained and disassembled, the sleeve ring 14 is pulled, and the sleeve ring 14 slides on the outer wall of the measurement channel 10 and squeezes the second spring 18 at the tail after being subjected to the force. Subsequently, the inner groove 15 inside the sleeve ring 14 coincides with the inner groove 15 inside the measurement channel 10, thereby providing the snap bead 16 with a slidable space. In the process of pulling out the inner tube 12, the snap bead 16 is no longer clamped on the outer connecting ring 13 but is pushed into the inner groove 15, thereby realizing the quick disassembly of the inner tube 12. The sleeve ring 14 is reset by the second spring 18. When the measurement pipeline has problems such as blockage, leakage or corrosion, the convenient disassembly can quickly disassemble the inner tube 12 by the maintenance personnel, so as to quickly locate and solve the problem. Without spending a lot of time dealing with complex disassembly procedures, the maintenance time is effectively shortened, thereby reducing the production loss caused by the shutdown of the equipment.

[0030] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
