Description

Technical Field

[0001] This utility model relates to the water affairs field, and in particular to a flow stabilizing pipe that can be installed quickly. Background Technology

[0002] In the water sector, in order to achieve accurate measurement, water meters (especially smart water meters) usually need to have flow stabilizing pipes of different lengths installed at both ends to ensure stable water flow.

[0003] A flow stabilizing pipe typically includes a straight pipe section and a first connector and a second connector located at both ends of the straight pipe section. The first connector is used to connect to water valves (such as gate valves, stop valves, etc.) in the pipeline, and the second connector is used to connect to a water meter.

[0004] Existing flow stabilizing pipes typically have a threaded first connector (internal or external thread) and a union nut for the second connector. Because the first connector is threaded, the following problems arise when connecting it to a water valve:

[0005] 1. Cumbersome installation. First, to ensure a good seal, Teflon tape is usually wrapped around the threaded connection during installation. If the Teflon tape is wrapped too thickly, it will not fit properly; if it is wrapped too thinly, leakage is likely to occur. In actual installation, repeated attempts and adjustments are often required, thus demanding a high level of skill from the installers.

[0006] 2. In addition, in order to ensure a tight fit, the above connection method requires the use of installation tools such as wrenches during the actual installation process. When the installation space is limited, it often increases the difficulty of operation and has a significant impact on the installation efficiency.

[0007] 3. Uncertain installation orientation. During the rotational installation of water valves, after tightening, the orientation of the valves often deviates from the expected angle. Therefore, the angle of the water valves needs to be adjusted by force, which can lead to stress cracking of the valves after installation due to excessive tension on the threads. Utility Model Content

[0008] This invention provides a flow stabilizer tube, the purpose of which is to overcome the problem of low installation efficiency in the assembly process of the prior art.

[0009] To achieve this objective, the present invention adopts the following technical solution:

[0010] A flow stabilizing tube, comprising:

[0011] The first connector, which may be a male or female connector;

[0012] The second connector is used to mate and connect with an external threaded connector.

[0013] The main body has the first and second connectors respectively located at both ends.

[0014] The male connector is formed as a hollow tube, and a limiting groove is provided on its outer side wall;

[0015] The female connector is formed into a hollow tube shape, and the side wall of the female connector has a socket that penetrates the inner wall of the female connector.

[0016] In the recommended embodiment, a first sealing ring is fitted onto the male connector, the limiting groove is located beside the first sealing ring, and the first sealing ring is located between the limiting groove and the end face of the male connector. The first sealing ring ensures a sealing effect.

[0017] In the recommended embodiment, a second sealing ring is fitted onto the male connector, and the limiting groove is located between the first and second sealing rings. The second sealing ring has a certain dustproof function and can effectively avoid the influence of impurities.

[0018] In the recommended embodiment, the male connector includes a sealing section and a limiting section sequentially from its end face. The outer diameter of the sealing section is smaller than the outer diameter of the limiting section, and the first sealing ring is fitted onto the sealing section. This provides protection for the first sealing ring during assembly and disassembly, preventing it from being cut.

[0019] In the recommended embodiment, a first protruding limiting portion is formed at the connection between the male connector and the main body. This facilitates axial positioning during assembly.

[0020] In the recommended embodiment, the limiting groove is arranged circumferentially around the male connector. No angle adjustment is required, facilitating assembly.

[0021] In the recommended embodiment, the socket is arranged tangentially to the female connector. This provides high structural stability and ease of manufacturing.

[0022] In the recommended embodiment, the female connector includes a large inner hole section and a small inner hole section sequentially from its port, with a step formed at the junction of the large and small inner hole sections. The insertion hole passes through the large inner hole section. During installation, this protects the mating parts and prevents the sealing ring on the mating parts from being cut.

[0023] In the recommended embodiment, the second connector is a union nut. When assembled with the water meter, the union nut rotates while the water meter remains stationary, ensuring the water meter is installed in the correct orientation.

[0024] In the recommended embodiment, one end of the main pipe is provided with a protruding second limiting part, and the swivel nut is movably sleeved on the main pipe and axially limited by the second limiting part. The second limiting part prevents the swivel nut from falling off the main pipe.

[0025] The beneficial effects of this utility model are:

[0026] This utility model sets the first connector of the flow stabilizing pipe as a male or female connector. During installation, it can be installed with external valves or pipelines by plugging them in, which can significantly improve installation efficiency. Attached Figure Description

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] Reference Figure 1 A flow stabilizing pipe includes a main pipe body 1, a first connector 2, and a second connector 3. The main pipe body 1 is a straight pipe, and its length is usually between 5cm and 10cm. Of course, its length can be adjusted appropriately according to the actual application scenario.

[0038] Simultaneously refer to Figure 3 The first connector 2 and the second connector 3 are respectively fixedly installed at both ends of the main body 1. In actual installation, the first connector 2 is usually used to connect with the water valve (gate valve 4 in this embodiment), and the second connector 3 is usually used to connect with the water meter 5 (usually a smart water meter).

[0039] Simultaneously refer to Figure 2 In this embodiment, the first connector 2 is a male connector, which is a hollow tubular structure. The male connector includes, sequentially from its end face, a sealing section 21, a limiting section 22, and a first limiting part 23. The outer diameter of the sealing section 21 is smaller than the outer diameter of the limiting section 22, and the outer diameter of the limiting section 22 is smaller than the outer diameter of the first limiting part 23. As can be seen from the figure, the first limiting part 23 protrudes outward from the junction of the male connector and the main pipe 1.

[0040] Continue to refer to Figure 1 The outer wall of the sealing section 21 is provided with a first sealing groove 211 and a limiting groove 212, both of which are arranged circumferentially around the sealing section 21. The outer wall of the limiting section 22 is provided with a second sealing groove 221.

[0041] Simultaneously refer to Figure 2 The male connector further includes a first sealing ring 10 and a second sealing ring 20. The first sealing ring 10 is nested in the first sealing groove 211 to ensure a sealing effect; the second sealing ring 20 is nested in the second sealing groove 221 and has a dustproof function. The first sealing ring 10 is close to the end face of the male connector, and the limiting groove 212 is located between the first sealing ring 10 and the second sealing ring 20.

[0042] In this embodiment, the second connector 3 is a swivel nut. The end of the main pipe body 1 away from the first connector 2 is provided with a protruding second limiting part 31. The swivel nut is movably sleeved on the main pipe body 1 and is axially limited by the second limiting part 31. When assembled with the water meter 5, the second connector 3 (swivel nut) rotates while the water meter 5 remains stationary, ensuring that the water meter 5 is installed in the correct orientation.

[0043] Reference Figure 3 , Figure 3 The figure shows an assembly example of the flow stabilizing pipe 100 in Embodiment 1. The two ends of the flow stabilizing pipe 100 are connected to a water meter 5 and a gate valve 4, respectively. As can be seen from the figure, both ends of the water meter 5 are equipped with threaded connectors 51. One end of the gate valve 4 is equipped with a female connector 41, which is used to mate with the male connector of the flow stabilizing pipe 100. The female connector 42 is a hollow tubular structure, and the side wall of the female connector 41 has a insertion hole 410 that penetrates the inner wall of the female connector 41.

[0044] The installation process is as follows:

[0045] The first connector 2 and the second connector 3 of the flow stabilizing pipe 100 are connected to the gate valve 4 and the water meter 5, respectively.

[0046] Specifically, the union nut of the second connector 3 is directly threaded to the threaded connector 51 of the water meter 5. When assembling with the water meter 5, the second connector 3 (union nut) rotates while the water meter 5 remains stationary, ensuring that the water meter 5 is installed in the correct orientation.

[0047] When connecting the first connector 2 and the gate valve 4, first insert the male connector of the flow stabilizer 100 into the female connector 41 of the gate valve 4 until the first limiting part 23 abuts against the end face of the female connector 41. At this time, the limiting groove 212 corresponds to the position of the insertion hole 410, and the male and female connectors are sealed together. Then, Figure 3 The pin 6 is inserted into the insertion hole 410 and is confined within the limiting groove 212, thereby achieving the effect of mutual axial limiting between the male connector of the flow stabilizer 100 and the female connector 41 of the gate valve 4.

[0048] This invention sets the first connector 2 of the flow stabilizer pipe 100 as a male connector. During installation, it can be installed with an external water valve via a plug-in connection, significantly improving installation efficiency. Moreover, the water valve (the gate valve in this embodiment) does not need to be rotated during installation, thus ensuring that the water valve is installed in the correct orientation.

[0049] Example 2

[0050] Reference Figure 4 This embodiment is basically the same as the structure of the first embodiment above. The main difference is that in this embodiment, the first connector 2′ of the flow stabilizing pipe 200 is a female connector. The female connector is a hollow tubular structure. The female connector includes a large inner hole section 21′ and a small inner hole section 22′ from its port. A step 23′ is formed at the junction of the large inner hole section 21′ and the small inner hole section 22′. An insertion hole 20′ is provided on the outer wall of the large inner hole section 21′ of the female connector. The insertion hole 20′ penetrates the inner wall of the large inner hole section 21′ and is arranged along the tangential direction of the female connector.

[0051] Reference Figure 5 , Figure 5 The figure shows an assembly example of the flow stabilizing pipe 200 in Embodiment 2. The two ends of the flow stabilizing pipe 200 are connected to the water meter 5 and the gate valve 4, respectively. As can be seen from the figure, both ends of the water meter 5 are equipped with threaded connectors 51. One end of the gate valve 4 is equipped with a male connector 42, which is used to mate with the female connector of the flow stabilizing pipe 200.

[0052] The installation process is as follows:

[0053] The first connector 2′ and the second connector 3 of the flow stabilizing pipe 200 are connected to the gate valve and the water meter, respectively.

[0054] Specifically, the union nut of the second connector 3 is directly threaded to the threaded connector 51 of the water meter 5. When assembling with the water meter 5, the second connector 3 (union nut) rotates while the water meter 5 remains stationary, ensuring that the water meter 5 is installed in the correct orientation.

[0055] When connecting the first connector 2' and the gate valve 4, first insert the male connector 42 of the gate valve 4 into the female connector of the flow stabilizing pipe 200 until the limiting groove 420 corresponds to the position of the insertion hole 20', and the male and female connectors are sealed together. Then, ... Figure 5 The pin 6 is inserted from the insertion hole 20′ and is confined within the limiting groove 420, thereby axially limiting the male connector of the gate valve 4 and the female connector of the flow stabilizer 200.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
