Description

Technical Field

[0001] This utility model is a retainer for a flow meter, belonging to the field of flow detection equipment. Background Technology

[0002] Flow meters are widely used in industrial production to measure the fluid flowing through pipes. When using a flow meter to measure the fluid in a pipe, it is necessary to measure the temperature of the fluid in the pipe to compensate for the measured value and make the final measurement more accurate. Usually, the temperature sensor is fixed to the outer wall of the pipe between the flow meter support plate and the manifold by a retainer. The commonly used retainer structure is an elastic snap-fit ​​fixing structure, which is usually composed of parts such as pull plate, pull rod, movable plate, spring, locking block, and locking groove.

[0003] In existing technology, when it is necessary to remove the temperature sensor, it is necessary to manually pull the pull plate, which drives the movable plate through the pull rod. The movable plate slides on the fixed rod through the sliding hole, and at the same time, the spring is squeezed, causing the movable plate to drive the locking block out of the slot. Then, the connecting pipe is manually rotated to make the fixed block and the mounting block misaligned, so that the retainer can be separated from the connecting pipe and the fixed temperature sensor can be removed. The flow meter pipe is equipped with a temperature sensor. During the fluid transportation process, the collision between the liquid and the pipe will cause the pipe to vibrate, which will cause the retainer to resonate. The elastic clamp of the spring will loosen with the vibration, which will cause the temperature sensor to shift. This can easily lead to poor contact between instruments and measurement errors.

[0004] In summary, this utility model provides a retainer for a flow meter to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a retainer for a flow meter to solve the problem mentioned in the background art, which leads to a decrease in the accuracy of flow meter data measurement due to an unstable temperature sensor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a retainer for a flow meter, comprising a tube body, a temperature sensor, and a detection rod. Mounting rings are fixedly fitted on both sides of the outer wall of the tube body. Mounting plates are fixedly connected to the tops of the two mounting rings. The detection rod is mounted on the bottom of the temperature sensor. Fastening nuts penetrate the opposite sides of the two mounting plates. Threaded rods penetrate the opposite sides of the two mounting plates through the fastening nuts. Rotary blocks are fixedly connected to the separated ends of the two threaded rods. Clamping plates are rotatably connected to the opposite ends of the two threaded rods located on both sides of the temperature sensor. A sealing and reinforcing assembly is fitted outside the detection rod and above the tube body.

[0007] Furthermore, each of the two clamping plates has a clamping groove on its opposite side, and the inner wall of the clamping groove on each of the two clamping plates is fixedly bonded with an anti-slip pad.

[0008] Furthermore, the fastening nut is threadedly connected to the threaded rod, and the fastening nut is fixedly connected to the mounting plate.

[0009] Furthermore, the two clamps are curved in an arc shape and are mirror-symmetrical.

[0010] Furthermore, the sealing and reinforcing assembly includes a through hole, two threaded holes, and a reinforcing plate. The through hole is located at the top of the tube and directly below the temperature sensor. One end of the detection rod passes through the through hole and extends into the tube. The reinforcing plate is fitted over the detection rod and is located directly above the tube. Screws pass through both sides of the top of the reinforcing plate. The two threaded holes are located at the top of the tube and directly below the two screws. A sealing ring is fitted over the detection rod and at the bottom of the reinforcing plate.

[0011] Furthermore, the top of the through hole is shaped like an inverted frustum, and the main cross-section of the sealing ring is also shaped like an inverted frustum.

[0012] Furthermore, the top of the sealing ring is fixedly connected to the bottom of the reinforcing plate, and the diameter of the through hole is smaller than the diameter of the sealing ring.

[0013] The beneficial effects of this utility model are:

[0014] By aligning the detection rod at the bottom of the temperature sensor with the through hole on the pipe body, extending one end of the detection rod into the interior of the pipe body, and simultaneously rotating two rotating blocks in both directions, the two threaded rods rotate in both directions on the fastening nuts, pushing the two clamping plates to move closer together and shorten the distance, thus stably clamping the temperature sensor. Then, the connection between the detection rod and the pipe body is reinforced by the sealing and reinforcement components, and the temperature sensor and detection rod are fixed. This effectively avoids the phenomenon of the temperature sensing element being displaced as a whole when the flow meter pipe vibrates, thus improving the accuracy of the measurement data.

[0015] The reinforcing plate inside the sealing and reinforcing assembly is moved down. As the reinforcing plate moves down, the screws can be rotated and tightened inside the threaded hole, thereby fixing the reinforcing plate to the pipe body. At the same time, the reinforcing plate can squeeze the sealing ring into the through hole. Since the diameter of the through hole is smaller than the diameter of the sealing ring, the surface of the sealing ring and the inner wall of the through hole are squeezed against each other, which can effectively improve the sealing performance at the connection between the detection end rod and the pipe body.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a retainer for a flow meter, including a tube body 1, a temperature sensor 3, and a detection rod 11. The tube body 1 is used to transport liquid flow and is part of the flow meter. Mounting rings 2 are fixedly fitted on both sides of the outer wall of the tube body 1. Mounting plates 4 are fixedly connected to the top of each of the two mounting rings 2. The detection rod 11 is installed at the bottom of the temperature sensor 3. Fastening nuts 5 penetrate each opposite side of the two mounting plates 4. Threaded rods 6 penetrate each opposite side of the two mounting plates 4 through the fastening nuts 5. Rotating blocks 10 are fixedly connected to the separated ends of the two threaded rods 6. Clamping plates 7 are rotatably connected to the opposite ends of the two threaded rods 6 located on both sides of the temperature sensor 3. A sealing and reinforcing assembly 9 is fitted outside the detection rod 11 and above the tube body 1. Each of the two clamping plates 7 has a clamping groove on one side of its opposite side. Anti-slip pads 8 are fixedly adhered to the inner wall of the clamping grooves on both clamping plates 7. The anti-slip pads 8 can increase the friction when the two clamping plates 7 clamp the temperature sensor 3, thereby improving the installation stability of the temperature sensor 3. The fastening nut 5 is threadedly connected to the threaded rod 6 and is fixedly connected to the mounting plate 4. The two clamping plates 7 are curved in an arc shape and are mirror symmetrical.

[0024] Please see Figure 2-4 The sealing and reinforcing assembly 9 includes a through hole 91, two threaded holes 92, and a reinforcing plate 93. The through hole 91 is located at the top of the tube body 1 and directly below the temperature sensor 3. One end of the detection rod 11 passes through the through hole 91, penetrates the tube body 1, and extends into the interior of the tube body 1. The reinforcing plate 93 is fitted over the detection rod 11 and is located directly above the tube body 1. Screws 95 penetrate both sides of the top of the reinforcing plate 93. The two threaded holes 92 are located at the top of the tube body 1 and directly below the two screws 95. A sealing ring 94 is fitted over the detection rod 11 and at the bottom of the reinforcing plate 93. The top of the through hole 91 is shaped like an inverted frustum, and the main cross-section of the sealing ring 94 is also shaped like an inverted frustum. The top of the sealing ring 94 is fixedly connected to the bottom of the reinforcing plate 93. The inner diameter of the through hole 91 is smaller than [missing information]. The outer diameter of the sealing ring 94 is matched with the threaded hole 92 and the screw 95. The reinforcing plate 93 moves down so that the sealing ring 94 partially extends into the through hole 91. Then the screw 95 is rotated and tightened so that it enters the threaded hole 92 and pushes the reinforcing plate 93 and the sealing ring 94 down, thereby fixing the reinforcing plate 93 on the tube body 1. At this time, the reinforcing plate 93 can squeeze the sealing ring 94 into the through hole 91. Since the diameter of the through hole 91 is smaller than the diameter of the sealing ring 94, the surface of the sealing ring 94 and the inner wall of the through hole 91 are squeezed against each other, which can effectively improve the sealing performance at the connection between the detection end rod 11 and the tube body 1. Since the sealing ring 94 can be squeezed and fixed at the connection between the detection end rod 11 and the tube body 1, the detection end rod 11 of the temperature sensor 3 can be reinforced.

[0025] Detailed Implementation: The tube body 1 is used to transport liquid flow and is part of the flow meter. By aligning the detection end rod 11 at the bottom of the temperature sensor 3 with the through hole 91 on the tube body 1, penetrating the tube body 1, and extending one end of the detection end rod 11 into the interior of the tube body 1, while rotating the two rotating blocks 10 in both directions, the two threaded rods 6 are driven to rotate in both directions on the fastening nut 5. Then, the two threaded rods 6 can push the two clamping plates 7 to move closer to each other and shorten the distance. The temperature sensor 3 can be stably clamped by the clamping grooves on opposite sides of the two clamping plates 7. Anti-slip rubber pads 8 are adhered inside the clamping grooves of the two clamping plates 7. The anti-slip rubber pads 8 can increase the friction between the clamping plates 7 and the temperature sensor 3, effectively improving the assembly firmness between the temperature sensor 3 and the tube body 1, avoiding the phenomenon of the tube body 1 vibrating and causing the temperature sensor 3 to move during the flow measurement process, and effectively improving the stability of the flow meter.

[0026] The reinforcing plate 93 inside the sealing and reinforcing assembly 9 is moved down. While the reinforcing plate 93 is moving down, the screw 95 can be rotated and tightened inside the threaded hole 92, thereby fixing the reinforcing plate 93 on the tube body 1. At the same time, the reinforcing plate 93 can squeeze the sealing ring 94 into the through hole 91. Since the diameter of the through hole 91 is smaller than the diameter of the sealing ring 94, the surface of the sealing ring 94 and the inner wall of the through hole 91 are squeezed against each other, thereby effectively improving the sealing performance of the through connection between the detection end rod 11 and the tube body 1.

[0027] Since the sealing ring 94 can be squeezed and fixed at the connection between the detection end rod 11 and the pipe body 1, the detection end rod 11 of the temperature sensor 3 can be reinforced. At the same time, the temperature sensor 3 and the detection end rod 11 are fixed, which can effectively avoid the phenomenon that the temperature sensing element is displaced as a whole when the flow meter pipeline vibrates, thus improving the accuracy of the measurement data.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
