[0020] Example 1

[0021] like Figures 1 to 10 As shown, an ultrasonic flow sensor for fluoroplastic valve production application includes: The sensor mechanism includes a first communicating pipe 100 and a second communicating pipe 101. An accommodating cavity 102 is fixedly installed at one end of the first communicating pipe 100 and the second communicating pipe 101. A transducer 103 is installed inside the accommodating cavity 102. The sensor mechanism measures the medium passing through the first communicating pipe 100 and the second communicating pipe 101 through the transducer 103. A connecting mechanism, the connecting mechanism comprises a first connecting assembly and a second connecting assembly, the first connecting assembly is connected to the first communicating pipe 100, the second connecting assembly is connected to the second communicating pipe 101, and the connecting mechanism realizes the connection between the first communicating pipe 100 and the second communicating pipe 101 through the first connecting assembly and the second connecting assembly; The fixing mechanism includes a first fixing component and a second fixing component, the first fixing component is connected to the first connecting component, the second fixing component is connected to the second connecting component, the first fixing component includes a first clamping plate 401, and the second fixing component includes a second clamping plate 501. When the connecting mechanism controls the first connecting pipe 100 and the second connecting pipe 101 to be connected, the first clamping plate 401 and the second clamping plate 501 are driven to perform a clamping action through the first fixing component and the second fixing component.

[0022] like Figure 1 , Figure 3As shown, in a specific embodiment, the first connection assembly includes a first outer fixed ring 200, the first outer fixed ring 200 is fixedly sleeved on the outside of the first communicating pipe 100, the first outer fixed ring 200 has a first sleeve 201 and a second sleeve 202 rotatably sleeved at both ends, and a linkage module is arranged between the first sleeve 201 and the second sleeve 202, and the linkage module is used to drive the first sleeve 201 and the second sleeve 202 to rotate. In this setting, the first sleeve 201 and the second sleeve 202 maintain opposite directions under the drive of the linkage module.

[0023] like Figure 5 As shown, further, the linkage module includes a first gear ring 204 and a second gear ring 205, the first gear ring 204 is fixedly connected to the first sleeve ring 201, the second gear ring 205 is fixedly connected to the second sleeve ring 202, a gear 206 is meshed and connected between the first gear ring 204 and the second gear ring 205, the gear 206 is rotatably connected to the first outer fixed ring 200, a plurality of gears 206 are provided, and the first locking module and the second locking module are arranged at intervals. In this setting, the rotation of the gear 206 drives the first gear ring 204 and the second gear ring 205 to rotate, and then drives the first sleeve ring 201 and the second sleeve ring 202 to rotate.

[0024] like Figure 5 As shown, further, the first locking module includes a first clamping plate 207, which is fixedly mounted on the gear 206, and the second locking module includes a stopper 208, which is fixedly mounted on the gear 206, and a second clamping plate 209 is movably inserted on the stopper 208, and a rotating plate 210 is installed on the second clamping plate 209. In this configuration, since the gears 206 corresponding to the first locking module and the second locking module rotate in the same direction, the first clamping plate 207 and the second clamping plate 209 rotate in the same direction after rotating ninety degrees, and at this time, the second clamping plate 209 can be slid along the inside of the stopper 208 to make the second clamping plate 209 face the first clamping plate 207.

[0025] Example 2

[0026] like Figure 3-Figure 5As shown, in a specific embodiment, the second connection assembly includes a second outer fixed ring 300, the second outer fixed ring 300 is fixedly mounted on the outside of the second connecting pipe 101, and a locking plate 308 is fixedly mounted on the outside of the second outer fixed ring 300, the locking plate 308 is adapted to the first locking module and the second locking module, and the first locking module and the second locking module lock the first connection assembly with the second connection assembly through the locking plate 308. In this setting, when the first clamping plate 207 and the second clamping plate 209 rotate 90 degrees, only one end of the first clamping plate 207 and the locking plate 308 abut against each other, at this time, the second clamping plate 209 is slid so that one end thereof abuts against the other end of the locking plate 308, and since the gear 206 cannot rotate in the opposite direction under the meshing action with the first gear ring 204 and the second gear ring 205, the locking plate 308 cannot be moved out after being abutted by the first clamping plate 207 and the second clamping plate 209.

[0027] like Figure 3 , Figure 4 As shown, further, the second connection assembly also includes an elastic module, which includes an insertion rod 303, which is movably inserted into the second outer fixed ring 300, and a spring 304 is movably sleeved on the insertion rod 303.

The external connecting ring 306 is movably sleeved on the second outer fixed ring 300, and a rotating ring 301 is rotatably connected to one end of the second outer fixed ring 300, and an adapting groove 302 is provided on the rotating ring 301. A protrusion 203 is fixedly installed on the second sleeve ring 202, and the protrusion 203 is adapted to the adapting groove 302. In this setting, when the lock plate 308 is unlocked, the elastic force of the spring 304 acts on the protrusion 203 through the insertion rod 303 and the guide block 307, thereby disconnecting the first connecting pipe 100 from the second connecting pipe 101.

[0028] like Figure 7 , Figure 8 , Fig. 9As shown, further, a first transfer tube 400 is fixedly installed on the first connecting pipe 100, and a first clamping plate 401 is rotatably connected to the first transfer tube 400. The first fixed component also includes a slide rail 405, which is fixedly installed on the first connecting pipe 100. A slider 406 is slidably connected to the slide rail 405, and a connecting member 404 is fixedly installed on one end of the slider 406. Stop rods 403 are fixedly installed on both ends of the connecting member 404. A first push plate 402 is fixedly installed on the bottom of the first clamping plate 401, and the first push plate 402 is adapted to the stop rod 403. The other end of the slider 406 is rotatably connected to a pulling plate 407, and one end of the pulling plate 407 is rotatably connected to a fixing rod 408, and the fixing rod 408 is fixedly connected to the first ring 201. In this arrangement, the gear 206 rotates while driving the first gear ring 204 to rotate, the first gear ring 204 also drives the first sleeve ring 201 to rotate, the first sleeve ring 201 drives the fixed rod 408 to rotate, and drives the slider 406 to move upward through the pulling plate 407, the slider 406 drives the blocking rod 403 to move upward through the connecting piece 404, and the blocking rod 403 drives the first clamping plate 401 to clamp the outer wall of the measuring pipeline by resisting the first push plate 402.

[0029] like Figure 4 , Figure 5 , Fig.10 As shown, further, a second transfer tube 500 is fixedly installed on the second connecting pipe 101, and the second clamping plate 501 is rotatably connected to the second transfer tube 500. The second fixed assembly also includes a second push plate 502, and the second push plate 502 is fixedly installed on the bottom of the second clamping plate 501. One end of the second push plate 502 is rotatably connected to the first pull rod 503, and the bottom of the first pull rod 503 is rotatably connected to the limiting block 504. The limiting block 504 is movably connected with a limiting rod 505, and the bottom of the limiting rod 505 is fixedly installed on both sides of the second connecting pipe 101. The bottom of the first pull rod 503 is rotatably connected to the second pull rod 506, and one end of the second pull rod 506 is rotatably connected to the support plate 507, and one end of the support plate 507 is fixedly connected to the external ring 306. In this configuration, the protrusion 203 presses against the guide block 307 to drive the insertion rod 303 to move, and the insertion rod 303 drives the external ring 306 to move through the connecting ring 305. The movement of the external ring 306 drives the support plate 507 to move at the same time. The support plate 507 drives the limit block 504 to move upward through the second pull rod 506. The limit block 504 drives one end of the first pull rod 503 to move upward, thereby driving the second push plate 502 to move and flipping the second clamping plate 501. At this time, the second clamping plate 501 clamps the outer wall of the measuring pipeline.

[0030] The first clamping plate 401 and the second clamping plate 501 have the same structure, and the inner walls of both are provided with tooth-shaped inner grooves.

[0031] Example 3

[0032] like Figure 2As shown, in a specific embodiment, a pressure block 104 is further provided inside the accommodating chamber 102, and the pressure block 104 is used to press against the transducer 103. A nut cover 105 is also installed at one end of the accommodating chamber 102 for closing the accommodating chamber 102. In this configuration, the pressure block 104 presses against the transducer 103 to prevent it from shaking and causing inaccurate measurement results.

[0033] like Figure 6 As shown, further, a protrusion 106 is fixedly installed at one end of the first connecting pipe 100, and a groove 107 is opened at one end of the second connecting pipe 101, and the protrusion 106 is adapted to the groove 107. In this configuration, the protrusion 106 is configured in a truncated cone shape, and a sealing gasket is provided between the protrusion 106 and the groove 107 to increase its sealing performance.

[0034] The implementation principle of the ultrasonic flow sensor for fluoroplastic valve production of this embodiment is as follows: when measuring, the medium flows between the first transfer tube 400, the first connecting pipe 100, the second connecting pipe 101 and the second transfer tube 500, so that the transducer 103 can collect information. By setting two transducers 103, the accuracy of the measurement can be improved; During installation, first align the first transfer tube 400 and the second transfer tube 500 with the measuring pipeline, and at the same time place the first clamping plate 401 and the second clamping plate 501 on the outside of the measuring pipeline, and align the first connecting pipeline 100 with the second connecting pipeline 101. At this time, the protruding nozzle 106 is inserted into the groove 107, and the protruding block 203 is inserted into the adapting groove 302. At the same time, the protruding block 203 abuts against the guide block 307 to drive the insertion rod 303 to move. The insertion rod 303 drives the outer ring 306 to move through the connecting ring 305. The outer ring 306 moves and drives the support plate 507 to move at the same time. The support plate 507 drives the limit block 504 to move upward through the second pull rod 506. The limit block 504 drives one end of the first pull rod 503 to move upward, thereby driving the second push plate 502 to move, and flipping the second clamping plate 501. At this time, the second clamping plate 501 clamps the outer wall of the measuring pipeline. After the first communicating pipe 100 is aligned with the second communicating pipe 101, the rotating plate 210 located on the side of the first outer fixed ring 200 is rotated, and the rotating plate 210 drives the gear 206 connected thereto to rotate, and the gear 206 drives the second gear ring 205 to rotate through meshing, and the second gear ring 205 drives the first outer fixed ring 200 to rotate, and the first outer fixed ring 200 drives the rotating ring 301 to rotate through the protrusion 203 and the adapting groove 302, so that the position of the adapting groove 302 can be staggered with the spring 304, so that the elastic force of the spring 304 no longer acts on the first communicating pipe 100 and its connecting structure; The gear 206 rotates while driving the first clamping plate 207 and the second clamping plate 209 to rotate. The first clamping plate 207 is clamped into one end of the locking plate 308. At this time, the first clamping plate 207 and the second clamping plate 209 are in the same rotation direction. The second clamping plate 209 is slid to make it rotate in the opposite direction to the first clamping plate 207. At this time, the second clamping plate 209 is clamped into the other end of the locking plate 308, thereby locking the locking plate 308. The gear 206 rotates while driving the first gear ring 204 to rotate, and the first gear ring 204 drives the first sleeve ring 201 to rotate at the same time, and the first sleeve ring 201 drives the fixed rod 408 to rotate, and drives the slider 406 to move upward through the pulling plate 407, and the slider 406 drives the blocking rod 403 to move upward through the connecting piece 404, and the blocking rod 403 drives the first clamping plate 401 to clamp the outer wall of the measuring pipeline by abutting against the first push plate 402; When disassembling, it is only necessary to reset the gear 206 to unlock the lock plate 308. At this time, the elastic force of the spring 304 acts on the protrusion 203 to separate the first connecting pipe 100 from the second connecting pipe 101. At the same time, the first clamping plate 401 and the second clamping plate 501 lose resistance and open, so that the measuring pipeline can be detached.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
