Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent sensors, and in particular relates to an ultrasonic flow sensor used in the production of fluoroplastic valves. Background Art

[0002] Ultrasonic flow sensors typically use the velocity difference method to detect liquid flow within a pipeline. This method uses the time difference between ultrasonic waves traveling upstream and downstream of the liquid to calculate the flow velocity. When installing an ultrasonic flow sensor within a pipeline, the angles between the ultrasonic transmitter and receiver must be adjusted to improve measurement accuracy. Ultrasonic flow sensors are often used for inspection during the production of fluoroplastic valves.

[0003] Chinese patent application CN210426647U discloses a rod assembly for an ultrasonic flow sensor, comprising a transducer rod and a rod connecting block. The rod has a positioning slot, mounting hole, and threading hole at the top. An ultrasonic transducer is mounted within the rod. The transducer rod and rod connecting block are fixedly connected via the positioning slot and mounting hole. The transducer rod and rod connecting block are integrally inserted into a vertical hole in an ultrasonic flowmeter. The rod connecting block is fixedly mounted to the positioning slot and mounting hole at the top of the rod, fixing the installation angle of the ultrasonic flow sensor. Once the rod is inserted into the vertical hole, manual adjustment of the sensor angle is unnecessary, ensuring accurate measurement during assembly.

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0041] Example 1

[0042] like Figures 1 to 10 As shown, an ultrasonic flow sensor for fluoroplastic valve production application includes:

[0043] The sensor mechanism includes a first communicating pipe 100 and a second communicating pipe 101. An accommodating cavity 102 is fixedly mounted at one end of each of the first communicating pipe 100 and the second communicating pipe 101. A transducer 103 is mounted 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.

[0044] The connecting mechanism includes a first connecting component and a second connecting component. The first connecting component is connected to the first communicating pipe 100, and the second connecting component is connected to the second communicating pipe 101. The connecting mechanism realizes the connection between the first communicating pipe 100 and the second communicating pipe 101 through the first connecting component and the second connecting component.

[0045] The fixing mechanism includes a first fixing component and a second fixing component. The first fixing component is connected to the first connecting component, and 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 connection between the first communicating pipe 100 and the second communicating pipe 101, 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.

[0046] like Figure 1 、 Figure 3 As shown, in a specific embodiment, the first connecting assembly includes a first outer fixed ring 200, which is fixedly sleeved on the outside of the first connecting pipe 100. A first ring 201 and a second ring 202 are rotatably sleeved at both ends of the first outer fixed ring 200. A linkage module is provided between the first ring 201 and the second ring 202, and the linkage module is used to drive the first ring 201 and the second ring 202 to rotate. In this configuration, the first ring 201 and the second ring 202 maintain opposite directions under the drive of the linkage module.

[0047] like Figure 5 As shown, the linkage module further 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, and the second gear ring 205 is fixedly connected to the second sleeve ring 202. A gear 206 is meshedly 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. There are multiple gears 206, and first and second locking modules are arranged at intervals. In this configuration, the rotation of the gear 206 simultaneously drives the rotation of the first gear ring 204 and the second gear ring 205, which in turn drives the rotation of the first sleeve ring 201 and the second sleeve ring 202.

[0048] like Figure 5 As shown, the first locking module further includes a first clip 207 fixedly mounted on the gear 206, and the second locking module includes a stopper 208 fixedly mounted on the gear 206. The stopper 208 is movably connected to the stopper 208, and a second clip 209 is mounted on the second clip 209. A rotating plate 210 is mounted on the second clip 209. In this configuration, since the gears 206 corresponding to the first and second locking modules rotate in the same direction, the first clip 207 and the second clip 209 rotate in the same direction after rotating 90 degrees. At this time, the second clip 209 can be slid along the inside of the stopper 208 to make the second clip 209 face the first clip 207.

[0049] Example 2

[0050] like Figure 3-Figure 5As shown, in a specific embodiment, the second connecting assembly includes a second outer fixing ring 300, which is fixedly mounted on the outside of the second connecting pipe 101. A locking plate 308 is fixedly mounted on the outside of the second outer fixing ring 300. The locking plate 308 is adapted to the first locking module and the second locking module. The first locking module and the second locking module lock the first connecting assembly and the second connecting assembly through the locking plate 308. In this configuration, when the first clamping plate 207 and the second clamping plate 209 are rotated 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 abuts against the other end of the locking plate 308. Since the gear 206 cannot rotate in the opposite direction due to the meshing action with the first gear ring 204 and the second gear ring 205, the locking plate 308 cannot be removed after being abutted by the first clamping plate 207 and the second clamping plate 209.

[0051] like Figure 3 、 Figure 4 As shown, the second connecting assembly further includes an elastic module, which includes an insert rod 303, which is movably inserted into the second outer fixed ring 300. A spring 304 is movably sleeved on the insert rod 303. A guide block 307 is fixedly mounted on one end of the insert rod 303. A connecting ring 305 is fixedly mounted on the insert rod 303, and an external connecting ring 306 is fixedly mounted on the outer side of the connecting ring 305. The external connecting ring 306 is movably sleeved on the second outer fixed ring 300. One end of the second outer fixed ring 300 is rotatably connected to a rotating ring 301. The rotating ring 301 has an adapting groove 302 defined therein. A protrusion 203 is fixedly mounted on the second sleeve ring 202, and the protrusion 203 is adapted to fit within the adapting groove 302. In this arrangement, when the lock plate 308 is unlocked, the elastic force of the spring 304 acts on the protrusion 203 through the insert rod 303 and the guide block 307, thereby disconnecting the first connecting pipe 100 from the second connecting pipe 101.

[0052] like Figure 7 、 Figure 8 、 Figure 9As shown, further, a first transfer tube 400 is fixedly installed on the first connecting pipe 100, and a first splint 401 is rotatably connected to the first transfer tube 400. The first fixed assembly 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. A blocking rod 403 is fixedly installed on both ends of the connecting member 404. A first push plate 402 is fixedly installed on the bottom of the first splint 401, and the first push plate 402 is adapted to the blocking 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 setting, the gear 206 rotates while driving the first gear ring 204 to rotate, and the first gear ring 204 also drives the first ring 201 to rotate, and the first ring 201 drives the fixed rod 408 to rotate, and drives the slider 406 to move upward by pulling the plate 407, and the slider 406 drives the baffle rod 403 to move upward through the connecting piece 404, and the baffle rod 403 drives the first clamping plate 401 to clamp the outer wall of the measuring pipeline by pressing against the first push plate 402.

[0053] like Figure 4 、 Figure 5 、 Figure 10 As shown, further, a second transfer tube 500 is fixedly installed on the second connecting pipe 101, and the second splint 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 splint 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 plugged 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 setting, 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, and then drives the second push plate 502 to move and flips the second clamping plate 501. At this time, the second clamping plate 501 clamps the outer wall of the measuring pipeline.

[0054] The first clamping plate 401 and the second clamping plate 501 have the same structure, and both have tooth-shaped inner grooves formed on their inner walls.

[0055] Example 3

[0056] like Figure 2As shown, in a specific embodiment, a pressure block 104 is further disposed within the accommodating chamber 102 to press against the transducer 103. A nut 105 is also mounted at one end of the accommodating chamber 102 to seal the accommodating chamber 102. In this arrangement, the pressure block 104 presses against the transducer 103 to prevent it from shaking and causing inaccurate measurement results.

[0057] like Figure 6 As shown, further, a protruding nozzle 106 is fixedly mounted on one end of the first communicating pipe 100, and a groove 107 is opened on one end of the second communicating pipe 101, and the protruding nozzle 106 is adapted to the groove 107. In this arrangement, the protruding nozzle 106 is arranged in a truncated cone shape, and a sealing gasket is arranged between the protruding nozzle 106 and the groove 107 to improve its sealing performance.

[0058] The implementation principle of the ultrasonic flow sensor for fluoroplastic valve production in this embodiment is as follows: During measurement, 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, allowing the transducer 103 to collect information. The provision of two transducers 103 can improve measurement accuracy.

[0059] 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 pipe 100 with the second connecting pipe 101. At this time, the protruding nozzle 106 is inserted into the groove 107, and the protrusion 203 is inserted into the adapting groove 302. At the same time, the protrusion 203 presses 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 movement of the outer 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.

[0060] After the first communicating pipe 100 and the second communicating pipe 101 are aligned, the rotating plate 210 located on the side of the first outer fixed ring 200 is rotated. The rotating plate 210 drives the gear 206 connected thereto to rotate. The gear 206, through engagement, drives the second gear ring 205 to rotate. The second gear ring 205 drives the first outer fixed ring 200 to rotate. The first outer fixed ring 200 drives the rotating ring 301 to rotate via the protrusion 203 and the adapting groove 302. This allows the position of the adapting groove 302 to be offset from 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.

[0061] 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 lock 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 so that it rotates 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 lock plate 308, thereby locking the lock plate 308.

[0062] 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. The blocking rod 403 presses against the first push plate 402 to drive the first clamping plate 401 to clamp the outer wall of the measuring pipe.

[0063] 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, so that the first connecting pipe 100 and the second connecting pipe 101 can be separated. At the same time, the first clamping plate 401 and the second clamping plate 501 lose resistance and open, allowing the measuring pipeline to be detached.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. 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.
