Description

Technical Field

[0001] The utility model relates to the field of pipeline flow measurement, in particular to a multi-diameter pipeline flow measurement device. Background Art

[0002] Flow measurement is widely used in industrial and agricultural production, scientific research, foreign trade and all areas of life. In the production of the petroleum industry, from oil extraction, transportation, refining and processing to trade sales, flow measurement runs through the entire process. Any link cannot be separated from flow measurement, otherwise the normal production and trade exchanges of the petroleum industry will not be guaranteed. In the chemical industry, inaccurate flow measurement will cause an imbalance in the distribution ratio of chemical components, and the quality of products cannot be guaranteed. In serious cases, production safety accidents may occur. In the production of the power industry, the measurement and regulation of the flow of liquids, gases, steam and other media occupy an important position. Existing flow meters can only measure the flow of pipelines with specific diameters, but cannot perform centralized measurement of pipelines with multiple diameters.

[0003] According to the published patent 202022374173.3, the multi-diameter pipeline flow measuring device includes a support and a first pipeline unit and a second pipeline unit arranged on the support. The first pipeline unit and the second pipeline unit each include a plurality of corresponding pipelines of different diameters, and the corresponding two pipelines are connected via a flow meter. The utility model adopts a multi-diameter pipeline flow measurement device of the above structure, which can simultaneously measure the flow of pipelines with different diameters, saves measurement time, and improves measurement efficiency. In the process of realizing the utility model, the inventor finds that at least the following problems in the prior art have not been solved. Although the multi-diameter pipeline flow measurement device can simultaneously measure the flow of pipelines with different diameters, saves measurement time, improves measurement efficiency, and solves the problem that the existing flow meter can only measure the flow of pipelines with specific diameters, but cannot perform centralized measurement on pipelines with multiple diameters, during use, the traditional multi-diameter pipeline flow measurement device rotates the fixed disk of the first pipeline unit or the fixed disk of the second pipeline unit so that the pipelines on the two correspond one to one, but the flow meter interface size is fixed, so the flow meter docking pipeline diameter is also fixed. Even if multiple pipelines with different diameters can be set to rotate, there is still a problem that it cannot be docked with a flow meter with a fixed interface size, which affects the flow detection of pipelines with different diameters. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a multi-diameter pipeline flow measurement device to solve the current traditional multi-diameter pipeline flow measurement device, rotate the fixed disk of the first pipeline unit or the fixed disk of the second pipeline unit to make the pipelines on the two correspond one to one, but the flow meter interface size is fixed, so the flow meter docking pipeline diameter is also fixed, even if a plurality of pipelines with different diameters can be set to rotate, there is still a technical problem that they cannot be docked with the flow meter with a fixed interface size, which affects the flow detection of pipelines with different diameters.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a multi-diameter pipeline flow measurement device, including a concave rod body, and also including:

[0006] Two damping bearings are respectively passed through two sides of the outside of the concave rod body;

[0007] A measuring mechanism is passed through the outside of the two damping bearings, and the measuring mechanism includes two rotating cylinders, and the damping bearings are passed through the inside of the two rotating cylinders, and the damping bearings are fixedly connected to the penetration positions of the rotating cylinders;

[0008] A plurality of placement holes are provided on one side of the rotating cylinder, and inserting cylinders are inserted into both sides of the placement holes, and one side of the inserting cylinder is connected with a threaded connection pipe head.

[0009] Preferably, a thread groove is provided on the other side of the insert tube, and the thread grooves in the multiple insert tubes are respectively provided according to the different diameters of the multiple pipes.

[0010] Preferably, pipe bodies with different diameters are placed inside the plurality of placement holes, and threaded walls are provided on both sides of the outer wall of the pipe body, both sides of the pipe body extend into the thread groove, and the thread groove is threadedly connected to the thread wall.

[0011] Preferably, a connecting rod is fixed to the middle of the top end of the concave rod body, and a flow meter is fixed to the top of the connecting rod.

[0012] Preferably, a device bottom plate is fixed to the bottom of the concave rod body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model combines a rotating cylinder, an insert cylinder and a threaded connection pipe head, and a threaded groove matching pipes of different diameters is arranged on one side of the insert cylinder. The insert cylinder is threadedly connected to both sides of the pipe, and the threaded connection pipe head on the surface of the insert cylinder can be connected to the interface of the flow meter through the threaded connection pipe head, so that the sizes of both sides of the pipes of different diameters are unified, and the connection with the flow meter of the fixed size interface is realized, which solves the problem of traditional multi-diameter pipe flow measurement device. The fixed disk of the first pipe unit or the fixed disk of the second pipe unit is rotated to make the pipes on the two correspond one to one, but the interface size of the flow meter is fixed, so the pipe diameter of the flow meter connection pipe is also fixed. Even if a plurality of pipes of different diameters can be set to rotate, there is still a technical problem that they cannot be connected to the flow meter of the fixed interface size, which affects the flow detection of pipes of different diameters.

[0015] 2. The utility model combines the rotating cylinder, the placement hole and the insert cylinder, so that the insert cylinder and the pipeline can be rotated in the placement hole, so that the threaded connection pipe head on the side of the insert cylinder is screwed with the interface threads on both sides of the flow meter, which solves the problem that the pipelines of traditional measuring devices are fixed and need to be connected to the flow meter by plugging. However, most of the existing flow meters use a threaded connection method, which leads to an unstable connection problem. BRIEF DESCRIPTION OF THE DRAWINGS

First, pipes of different diameters are respectively placed in the plurality of placement holes 203 in the two rotating cylinders 2, and then the plurality of insert cylinders 204 are respectively inserted into the positions on both sides of the plurality of placement holes 203, and through the thread grooves 3 of different sizes on one side of the plurality of insert cylinders 204, the pipe bodies 3 of different diameters are connected. The threaded wall 301 on the surface of 02 is threadedly connected, so that the sizes of both sides of the pipes with different diameters are unified. After the connection is completed, the two rotating cylinders 2 are moved on the surface of the concave rod body 1, and the rotating cylinder 2 is rotated through the damping bearing 201, so that the threaded connection pipe heads 202 at different positions are connected to the interface positions on both sides of the flow meter 102, which solves the problem of the traditional multi-diameter pipeline flow measurement device. The fixed disk of the first pipeline unit or the fixed disk of the second pipeline unit is rotated to make the pipelines on the two correspond one by one, but the interface size of the flow meter 102 is fixed, so the diameter of the pipeline connected to the flow meter 102 is also fixed. Even if multiple pipelines with different diameters can be set to rotate, there is still a technical problem that they cannot be connected to the flow meter 102 with a fixed interface size, which affects the flow detection of pipelines with different diameters.

However, most of the existing flow meters 102 use a threaded connection method, which leads to an unstable connection problem.

[0023] It is worth noting that see Figure 1 A connecting rod 101 is fixed to the middle of the top of the concave rod body 1 , and a flow meter 102 is fixed to the top of the connecting rod 101 .

After the connection is completed, the two rotating cylinders 2 are moved on the surface of the concave rod body 1, and the rotating cylinder 2 is rotated through the damping bearing 201, so that the threaded connection pipe heads 202 at different positions are connected to the interface positions on both sides of the flow meter 102, and the insert cylinder 204 and the pipe body 302 can be rotated in the placement hole 203, so that the threaded connection pipe head 202 on the side of the insert cylinder 204 is screwed with the interface threads on both sides of the flow meter 102.
