Description

Technical Field

[0001] The utility model relates to the field of flow display meters, in particular to a flow display meter which is convenient to install. Background Art

[0002] A flow meter (also called a flow display instrument or a flow meter) is a device used to display flow signals and their accumulated totals.

[0003] In the current flow meter design, joints generally use nuts or threads. This design brings many inconveniences when maintaining and replacing the flow meter. Since the positions of the two ends of the water pipe are often fixed, whether the flow meter is disassembled or reinstalled, sufficient space is required to rotate and unlock the threaded joints. This requires that the water pipes at both ends must be moved relative to each other to free up sufficient operating space. However, such operations place high mobility requirements on the water pipe layout structure. If these requirements are not met, the water pipe layout may need to be readjusted or modified, which not only increases the complexity of the operation, but may also cause unnecessary damage to the water pipe structure, thereby shortening the service life of the water pipe. Therefore, the fixed joint design of the traditional flow meter limits its installation convenience and practicality to a certain extent.

[0004] Therefore, a flow display meter that is convenient to install is provided to solve the above problems. Utility Model Content

[0009] In order to make the flow meter adjustable to facilitate installation and removal of the joint, a joint assembly that moves closer to or away from the inlet end is provided on the inlet end, and a second nut joint that can move axially along the outlet end is provided on the outside of the outlet end; through the movable joint assembly and the second nut joint, the user can flexibly adjust the connection position of the flow meter and the pipeline according to actual conditions, which greatly improves the convenience of installation. Since the design of the joint assembly and the second nut joint has a certain degree of adjustability, the flow display meter can adapt to more application scenarios and installation environments.

[0010] Preferably, in order to realize the adjustable function of the joint assembly, the joint assembly includes an inner tube which is sleeved in the inlet end and moves axially along the inlet end, and a first joint nut which is rotatably installed on the end of the inner tube away from the inlet end; through the axial movement of the inner tube and the rotation of the first joint nut, the user can easily adjust the position of the joint assembly to adapt to pipe connections of different lengths and types.

[0011] Preferably, in order to ensure the sealing of the connection between the inner tube and the inlet end, the end of the inner tube away from the first joint nut has an anti-slip ring, and the outer wall of the anti-slip ring is provided with a piston sealing ring in contact with the inner wall of the inlet end; by providing an anti-slip ring at the end of the inner tube away from the first joint nut and installing the piston sealing ring on the outer wall of the anti-slip ring, the flow display meter not only enhances the sealing and prevents fluid leakage, but also ensures the stability of the inner tube.

[0012] Preferably, in order to prevent the inner tube from falling out of the inlet end, the inner edge of the port at the inlet end has an inner limit flange, and the inner diameter of the inner limit flange is smaller than the outer diameter of the anti-slip ring; by providing the inner limit flange, the inner tube can be effectively prevented from falling out of the inlet end when subjected to excessive thrust or vibration, thereby enhancing the safety of the flow display meter.

[0013] Preferably, in order to further improve the sealing effect between the inner tube and the inlet end, a telescopic sealing sleeve is sleeved on the outside of the inner tube, and the two ends of the telescopic sealing sleeve are respectively fixedly connected to the anti-slip ring and the inner limit flange; by sleeved the telescopic sealing sleeve on the outside of the inner tube and fixedly connected to the anti-slip ring and the inner limit flange, the flow display meter further improves the sealing effect between the inner tube and the inlet end while ensuring the accuracy of flow measurement.

[0014] Preferably, in order to improve the stability of the inner tube when it moves at the inlet end, the outer wall of the inner tube has at least three slide bars distributed in a circular array, and limiting slide grooves are opened at positions corresponding to the slide bars on the inner limit flange; by arranging slide bars on the outer wall of the inner tube and opening corresponding limiting slide grooves on the inner limit flange, the flow display meter improves the stability of the inner tube when it moves at the inlet end while ensuring measurement accuracy.

[0015] Preferably, in order to ensure the sealing effect when the joints are connected, the first sealing gasket and the second sealing gasket are respectively embedded at the ports of the inlet end and the outlet end; by embedding the first sealing gasket and the second sealing gasket at the ports of the inlet end and the outlet end of the flow display meter, this design significantly enhances the sealing of the connection between the equipment and the pipeline.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example 1

[0032] See also Figure 1-Figure 4 The utility model provides a technical solution: a conveniently installed flow display meter, comprising a flow meter body 1 and an inlet end 11 and an outlet end 12 located at both ends of the flow meter body 1.

[0033] The inlet end 11 is provided with a joint assembly 2 which moves closer to or away from the inlet end 11 , and the outlet end 12 is sleeved with a second nut joint 3 which can move axially along the outlet end 12 .

[0034] When in use, first move the joint assembly 2 to a suitable position so that the inlet end 11 of the flow meter can be easily connected to the upstream pipeline. Similarly, when disassembling, it can be conveniently separated from the upstream pipeline by moving the joint assembly 2. Secondly, fix or loosen its connection with the downstream pipeline by rotating the second nut joint 3. When installation is required, the nut joint can be rotated to make it tightly connected with the downstream pipeline; when disassembly is required, the nut joint can be rotated in the opposite direction.

[0035] Specifically, the joint assembly 2 includes an inner tube 21 which is sleeved in the inlet end 11 and moves axially along the inlet end 11, and a first joint nut 23 which is rotatably mounted on the end of the inner tube 21 away from the inlet end 11; the inner tube 21 is sleeved in the inlet end 11 and can move axially along the inlet end 11. This design allows the user to adjust the relative position of the inner tube 21 with respect to the inlet end 11 by moving the inner tube 21 according to the requirements of the pipeline connection.

[0036] Furthermore, the end of the inner tube 21 away from the first joint nut 23 has an anti-slip ring 211, and the outer wall of the anti-slip ring 211 is provided with a piston sealing ring 22 in contact with the inner wall of the inlet end 11; the piston sealing ring 22 is mounted on the outer wall of the anti-slip ring 211 and is in close contact with the inner wall of the inlet end 11. This design ensures the sealing between the inner tube 21 and the inlet end 11, and prevents fluid leakage from there.

[0037] It should be noted that the inner edge of the port of the inlet end 11 has an inner limit flange 111, and the inner diameter of the inner limit flange 111 is smaller than the outer diameter of the anti-slip ring 211; when the inner tube 21 moves in the inlet end 11 and approaches the inlet end 11 through the adjustment of the first joint nut 23, the anti-slip ring 211 will first contact the inner limit flange 111. Since the inner diameter of the inner limit flange 111 is smaller than the outer diameter of the anti-slip ring 211, the anti-slip ring 211 cannot continue to move inward, thereby limiting the inner tube 21 and preventing it from falling out of the inlet end 11.

[0038] Furthermore, a telescopic sealing sleeve 24 is sheathed on the outside of the inner tube 21, and the two ends of the telescopic sealing sleeve 24 are fixedly connected to the anti-slip ring 211 and the inner limit flange 111 respectively; when the inner tube 21 moves in the inlet end 11, due to the elastic characteristics of the telescopic sealing sleeve 24, it can be expanded and contracted with the movement of the inner tube 21. This elasticity ensures that no matter what position the inner tube 21 is in, the telescopic sealing sleeve 24 can fit tightly between the inner tube 21 and the inlet end 11, thereby effectively preventing the fluid from leaking from the gap between the two.

[0039] In addition, the outer wall of the inner tube 21 has at least three slide bars 212 distributed in a circular array, and a limiting slide groove 1111 is provided at the position corresponding to the slide bar 212 on the inner limit flange 111; when the inner tube 21 moves in the inlet end 11, the slide bar 212 will slide along the track of the limiting slide groove 1111, and this design makes the movement of the inner tube 21 more stable.

[0040] Among them, the first sealing gasket 4 and the second sealing gasket 5 are respectively embedded at the ports of the inlet end 11 and the outlet end 12; when the flow display meter is connected to the pipeline, the first sealing gasket 4 and the second sealing gasket 5 will be compressed between the joint and the pipeline. Due to the softness of the sealing gaskets, they can fit tightly on the surface of the joint and the pipeline, thereby effectively preventing the fluid from leaking from the joint. At the same time, the elasticity of the sealing gasket can also compensate for the tiny gap caused by inaccurate pipeline installation or vibration to a certain extent, further improving the sealing effect.

[0041] Example 2

[0042] Different from Example 1, Figure 5As shown, the outer edge of the port of the outlet end 12 has an outer limiting flange 121 for preventing the second nut joint 3 from detaching from the outlet end 12, and the outer wall of the outlet end 12 has a protective ring 122 for blocking the second nut joint 3 from approaching the flow meter body 1, wherein the distance between the protective ring 122 and the outer limiting flange 121 is equal to the length of the second nut joint 3; when the second nut joint 3 is away from the flow meter body 1, it will be blocked by the outer limiting flange 121 to prevent it from falling off, and when the second nut joint 3 is close to the flow meter body 1, it will be blocked by the protective ring 122 after moving a distance equal to its own length, thereby preventing the second nut joint 3 from contacting the flow meter body 1, thereby protecting the flow meter body 1 from collision or friction. At the same time, when docking the pipeline, the second nut joint 3 can move a distance toward the flow meter body 1, thereby making way for the outlet end 12 and providing docking space.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
