Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of Coriolis mass flow meters, and specifically relates to a flow diversion device for a Coriolis mass flow meter. Background Technology
[0002] The flow divider of a Coriolis mass flow meter is an important component of the meter. Its function is to guide the fluid to the measuring tube, ensuring that the fluid can flow evenly through the measuring tube, thereby guaranteeing the accuracy of the measurement results. The design of the flow divider makes the fluid flow path consistent with the vibration direction of the measuring tube, which facilitates the sensor to detect the phase difference and then calculate the mass flow rate.
[0003] In some existing Coriolis mass flow meters, the diversion device is connected to the pipes at both ends during use, and the pipe body is fixed by a bracket fixed to the inner wall of the Coriolis mass flow meter housing. However, this fixing position is generally far from the connection end between the pipe body and the diversion device. As the usage time increases, the pipe body is affected by factors such as vibration caused by fluid impact. The far fixing position will be difficult to meet the tightness requirements of the connection end between the diversion device and the flow pipe, which can easily cause loosening between the diversion device and the flow pipe, which is quite inconvenient. Utility Model Content
[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a flow divider for a Coriolis mass flow meter. This addresses the issue mentioned in the background section where existing flow dividers for some Coriolis mass flow meters connect to pipes at both ends during use. The pipe body is fixed to the inner wall of the Coriolis mass flow meter housing using a bracket. However, this fixing point is generally far from the connection end between the pipe body and the flow divider. With increased usage time, factors such as vibration caused by fluid impact on the pipe body make it difficult to meet the tightness requirements of the connection between the flow divider and the flow pipe, easily leading to loosening between the flow divider and the flow pipe, which is quite inconvenient.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a diverter for a Coriolis mass flow meter, comprising a main body and a support mechanism disposed on one side of the main body for supporting the outer wall of the tube near the connection end between the flow tube and the main body. The support mechanism includes a bracket fixedly connected to one side of the diverter. A base is fixedly connected to the top of the bracket. A first screw is rotatably connected to the inner side of the base. The outer sides of both ends of the first screw are rotatably connected to the bracket. A slider is threadedly connected to the outer side of the first screw. A sliding rod is symmetrically arranged at the bottom of the slider. The bracket is slidably connected to the outer side of the sliding rod. Support plates are symmetrically arranged on both sides of the slider. A plurality of limiting holes are symmetrically arranged on the top of the support plates. A second screw is threadedly connected to one side of the slider. The bracket is movably connected to the outer side of the second screw through a U-shaped sliding groove.
[0006] Preferably, the main body mechanism includes a diverter, with an input pipe fixedly connected to one side of the diverter and an exhaust port symmetrically arranged on the other side of the diverter.
[0007] Preferably, a washer is movably connected to the outer side of one end of the second screw, and the washer is located on one side of the leg.
[0008] Preferably, a knob is fixedly connected to the bottom end of the first screw, and the knob is located below the foot.
[0009] Preferably, a spring is movably connected to the outer side of the tip of the first screw, and the spring is located between the foot and the slider.
[0010] Preferably, the adjacent trays are fixedly connected by limiting pins, and the limiting pins are all located below one side of the tray.
[0011] Preferably, each of the trays has a spacer fixedly connected to its top, and the spacer is made of a flexible material.
[0012] Preferably, the limiting hole has a U-shaped structure, and the limiting hole penetrates the inner wall of the support piece.
[0013] Compared with the prior art, this utility model provides a flow diversion device for a Coriolis mass flow meter, which has the following beneficial effects:
[0014] 1. This utility model uses a support plate to install the main body mechanism onto the inner wall of the Coriolis mass flow meter housing. Then, two flow tubes are sequentially connected to the discharge port. Depending on the height of the flow tubes, the second screw is rotated counterclockwise to loosen it. Then, the knob is squeezed, and the first screw is rotated inside the stand, causing the slider to rise and fall vertically to the position where the septum at the top of the support plate supports the bottom outer wall of the flow tube. During the slider's rise and fall, the second screw adapts its position by sliding within a U-shaped groove. At this point, rotating the second screw clockwise further secures the slider. Finally, a cable tie is inserted through the limiting hole from the top outer wall of the flow tube, cooperating with the U-shaped... After adjusting the cable tie to the desired position using the limiting hole, tighten the cable tie. The flow tube is supported by the support plate and also bound by the cable tie. Finally, after assembling the Coriolis mass flow meter housing, the fluid delivered by the diverter is received. After being divided by the main body mechanism, the fluid flows evenly into the two flow tubes connected to the discharge interface. During long-term use, while the outer wall of the flow tube is supported by the internal buckle of the Coriolis mass flow meter, the part of the tube body near the main body mechanism is supported and bound, which can have better stability, thereby reducing the risk of vibration during fluid delivery in the flow tube causing a decrease in the tightness of the connection between the flow tube and the device.
[0015] 2. By incorporating a gasket, this utility model effectively reduces the loosening of the gasket during prolonged use, ensuring the stability of the gasket.
[0016] 3. By setting a spacer, this utility model can effectively reduce the wear on the outer wall of the flow tube during the support process.
[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4This utility model provides a technical solution: a diverter for a Coriolis mass flow meter, comprising a main body 1 and a support mechanism 2 disposed on one side of the main body 1 to support the outer wall of the tube near the connection end between the flow tube and the main body 1. The support mechanism 2 includes a bracket 201 fixedly connected to one side of the diverter 101, a base 202 fixedly connected to the top of the bracket 201, a first screw 203 rotatably connected to the inner side of the base 202, the bracket 201 rotatably connected to the outer sides of both ends of the first screw 203, and a slider 204 threadedly connected to the outer side of the first screw 203. A sliding rod 205 is symmetrically arranged on the part of the slider 204. A foot bracket 201 is slidably connected to the outside of the sliding rod 205. A support plate 206 is symmetrically arranged on both sides of the slider 204. Several limiting holes 207 are symmetrically arranged on the top of the support plate 206. A second screw 208 is threadedly connected to one side of the slider 204. The foot bracket 201 is movably connected to the outside of the second screw 208 through a U-shaped sliding groove 209. The main body mechanism 1 is installed as a whole on the inner wall of the Coriolis mass flow meter housing. Then, the two flow tubes are connected to the discharge port 103 in sequence. According to the height position of the flow tubes, the second screw 208 is rotated counterclockwise and loosened. Squeeze knob 4 and rotate the first screw 203 inside the stand 201. This causes the slider 204 to rise and fall vertically to the position where the septum 7 at the top of the support plate 206 supports the bottom outer wall of the flow tube. During the rise and fall of the slider 204, the second screw 208 adjusts its position by sliding within the U-shaped groove 209. Rotating the second screw 208 clockwise further secures the slider 204. Then, insert the cable tie through the limiting hole 207 from the top outer wall of the flow tube. After adjusting the cable tie to the desired position using the U-shaped limiting hole 207, tighten the cable tie. The flow tube then passes through the support plate 206... While being supported, the fluid is also bound by cable ties. After the Coriolis mass flow meter housing is assembled, the fluid delivered by the distributor 101 is received. After being split by the main body mechanism 1, the fluid flows evenly into the two flow pipes connected to the discharge port 103. During long-term use, while the outer wall of the flow pipe is supported by the internal buckle limit of the Coriolis mass flow meter, the part of the pipe body near the main body mechanism 1 is supported and bound, which can have better stability, thereby reducing the risk of vibration during fluid delivery in the flow pipe, which may cause a decrease in the tightness of the connection between the flow pipe and the device.
[0026] In this utility model, preferably, the main body mechanism 1 includes a flow divider 101. An input pipe 102 is fixedly connected to one side of the flow divider 101, and a discharge port 103 is symmetrically arranged on the other side of the flow divider 101. The main body mechanism 1 is installed as a whole on the inner wall of the Coriolis mass flow meter housing. Then, the two flow pipes are connected to the discharge port 103 in sequence. The fluid delivered by the flow divider 101 is received and the fluid flows evenly into the two flow pipes connected to the discharge port 103 after being divided by the main body mechanism 1.
[0027] In this utility model, preferably, a washer 3 is movably connected to the outer side of one end of the second screw 208. The washer 3 is located on one side of the stand 201, which can effectively reduce the loosening of the washer 3 during long-term use and ensure the stability of the washer 3.
[0028] In this utility model, preferably, a knob 4 is fixedly connected to the bottom end of the first screw 203. The knob 4 is located below the foot 201, which can effectively facilitate personnel to directly pinch and rotate it.
[0029] In this utility model, preferably, a spring 5 is movably connected to the outer side of the top end of the first screw 203. The spring 5 is located between the foot 201 and the slider 204, which can effectively ensure the stability of the position of the first screw 203 during use.
[0030] In this utility model, preferably, the adjacent support pieces 206 are fixedly connected with limiting pins 6, and the limiting pins 6 are all located below one side of the support piece 206, which can effectively reduce the amount of sagging generated by the support piece 206.
[0031] In this utility model, preferably, each support plate 206 has a spacer 7 fixedly connected to its top. The spacer 7 is made of flexible material, which can effectively reduce the wear on the outer wall of the flow tube during the support process.
[0032] In this utility model, preferably, the limiting hole 207 has a U-shaped structure, and the limiting hole 207 all penetrates the inner wall of the support piece 206, so that the horizontal position of the cable tie can be adjusted according to actual needs.
[0033] The working principle and usage process of this utility model are as follows: In use, the main body mechanism 1 is installed on the inner wall of the Coriolis mass flow meter housing. Then, the two flow tubes are sequentially connected to the discharge port 103. Depending on the height of the flow tubes, the second screw 208 is rotated counterclockwise and loosened. Then, the knob 4 is held, and the first screw 203 is rotated inside the stand 201, causing the slider 204 to rise and fall vertically to the position where the septum 7 at the top of the support plate 206 supports the bottom outer wall of the flow tube. During the rising and falling of the slider 204, the second screw 208 adapts to the position by sliding within the U-shaped groove 209. At this time, rotating the second screw 208 clockwise further secures the slider 204. Finally, the cable tie is removed from the top of the flow tube. The outer wall is inserted through the limiting hole 207. After adjusting the cable tie to the required position with the U-shaped limiting hole 207, the cable tie is tightened. The flow tube is supported by the support plate 206 and also bound by the cable tie. Finally, after the Coriolis mass flow meter housing is assembled, the fluid delivered by the distributor 101 is received. After the fluid is divided by the main body mechanism 1, it flows evenly into the two flow tubes connected to the discharge port 103. During long-term use, while the flow tube is supported by the internal buckle of the Coriolis mass flow meter on the outer wall, the part of the tube close to the main body mechanism 1 is supported and bound, which can have better stability, thereby reducing the risk of vibration during fluid delivery in the flow tube, which may cause a decrease in the tightness of the connection between the flow tube and the device.
