Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a pipeline flow stabilizing structure. Background Art

[0002] Secondary water supply refers to a water supply method that guarantees the water volume and pressure requirements of (super) high-rise buildings by building storage and pressurization facilities when the building's water pressure and water volume requirements exceed the capacity of the city's public water supply network. In secondary water supply renovation projects, water meters are an indispensable and important part.

[0003] Since the water flow in the water inlet pipe can easily rotate into a vortex or other turbulent water flow, causing the water flow to be too fast, if the water meter is directly connected to the water inlet pipe, it will easily affect the water meter's measurement of water flow, causing the water meter's measurement results to have a large deviation and be inaccurate.

[0004] In the prior art, in the secondary water supply renovation construction, the water meters commonly used in most residential areas are rotor-type mechanical water meters with specifications of 15mm and 20mm. The threaded interfaces at both ends of the meter are in the form of external threads, which need to be directly connected to internal threads that are one specification larger than themselves. For example, a DN15 water meter needs to be connected to a DN20 internal thread interface, and a DN20 water meter needs to be connected to a DN25 internal thread interface. Therefore, if the straight-through steady flow section is to be connected to a water meter of the same specification, it needs to be connected to the joint equipped with the water meter in front, and then connected to a valve of the same size as the steady flow section, which brings many inconveniences to the secondary water supply renovation construction.

[0037] The second flow stabilizing tube 2 is used to connect the water inlet end of the second valve 5 with the water outlet end of the water meter 3 .

[0038] In this embodiment, the water inlet of the water meter 3 is connected with the external water supply through the first flow stabilizing tube 1 and the first valve 4 in sequence, so that the water inlet of the water meter 3 is connected with a steady flow through the first flow stabilizing tube 1. At the same time, the water outlet of the water meter 3 is connected with the water use point through the second flow stabilizing tube 2 and the second valve 5 in sequence, so that the water outlet of the water meter 3 is connected with a steady flow through the second flow stabilizing tube 2. The structure is simple and easy to assemble, which can enable the water meter 3 to achieve a steady flow effect, thereby effectively improving the measurement accuracy of the water meter 3.

[0039] Further, the first flow stabilizing tube 1 includes a first input section 11 and a first output section 12 connected in sequence, the water inlet end of the first input section 11 is connected to the water outlet end of the first valve 4, and the water outlet end thereof is connected to the water inlet end of the water meter 3 through the first output section 12, the pipe diameter of the first input section 11 is the same as the pipe diameter of the water outlet end of the first valve 4, the pipe diameter of the first output section 12 is the same as the pipe diameter of the water inlet end of the water meter 3, and the pipe diameter of the first input section 11 is different from the pipe diameter of the first output section 12;

[0040] The second flow stabilizing tube 2 includes a second input section 21 and a second output section 22 which are connected in sequence. The water inlet end of the second input section 21 is connected to the water outlet end of the water meter 3, and the water outlet end thereof is connected to the water inlet end of the second valve 5 through the second output section 22. The pipe diameter of the second input section 21 is the same as the pipe diameter of the water outlet end of the water meter 3, the pipe diameter of the second output section 22 is the same as the pipe diameter of the water inlet end of the second valve 5, and the pipe diameter of the second input section 21 and the pipe diameter of the second output section 22 are different.

[0041] Preferably, the first flow stabilizing tube 1 further includes a first connecting section 13, through which the first input section 11 is connected to the first output section 12, and the diameters of the first input section 11, the first connecting section 13, and the first output section 12 are all different;

[0042] The second flow stabilizing tube 2 further includes a second connecting section 23, through which the second input section 21 is connected to the second output section 22, and the diameters of the second input section 21, the second connecting section 23, and the second output section 22 are all different.

[0043] In the present embodiment, the first flow stabilizing tube 1 comprises a first input section 11, a first connecting section 13 and a first output section 12 which are connected in sequence, that is, the first input section 11, the first connecting section 13 and the first output section 12 are connected together in sequence along the water inlet direction, the water inlet end of the first input section 11 is connected to the water outlet end of the first valve 4, and its water outlet end is connected to the water inlet end of the water meter 3 through the first connecting section 13 and the first output section 12 in sequence, so that the water inlet of the water meter 3 is stabilized by the first flow stabilizing tube 1. Since the pipe diameter of the first input section 11 is the same as the pipe diameter of the water outlet end of the first valve 4, the pipe diameter of the first output section 12 is the same as the pipe diameter of the water inlet end of the water meter 3, and the pipe diameter of the first input section 11 is different from the pipe diameter of the first output section 12, when the pipe diameter specifications of the first valve 4 and the water meter 3 are different, the water outlet end of the first valve 4 with different pipe diameters and the water inlet end of the water meter 3 can be quickly installed together directly through the first flow stabilizing tube 1.

[0044] In addition, the second flow stabilizing tube 2 includes a second input section 21, a second connecting section 23 and a second output section 22 connected in sequence, that is, the second input section 21, the second connecting section 23, and the second output section 22 are connected together in sequence along the water inlet direction, the water inlet end of the second input section 21 is connected to the water outlet end of the water meter 3, and its water outlet end is connected to the water inlet end of the second valve 5 through the second connecting section 23 and the second output section 22 in sequence, so that the water outlet of the water meter 3 is stabilized by the second flow stabilizing tube 2.

[0045] Since common specifications of stainless steel flow stabilizer tubes include: DN15 straight-through flow stabilizer section and DN20 straight-through flow stabilizer section. If the straight-through flow stabilizer section is to be connected to a water meter 3 of the same specification, the front end needs to be connected to the connector 6 equipped with the water meter 3, and the rear end needs to be connected to a valve of the same specification and size as the flow stabilizer section. In this way, the DN20 straight-through flow stabilizer section using the flow stabilizer tube structure in this embodiment can be directly connected to a water meter 3 of DN15 without the need for the water meter 3 connector 6, and then connected to a valve of the same specification and size as the flow stabilizer section. The flow stabilizer section with a variable diameter of 20-15 can be directly connected to a water meter 3 of DN15, and then connected to a DN15 valve. Similarly, the variable diameter flow stabilizer section with a specification of 25-20 can be directly connected to a water meter 3 of DN20, and then connected to a DN20 valve.

[0046] In this embodiment, the flow stabilizer is made of iron or stainless steel, so that the flow stabilizer can be formed by welding. Since the structures of the first flow stabilizer 1 and the second flow stabilizer 2 are the same, only the first flow stabilizer 1 is used as an example for description in this embodiment, and the others are not repeated. When the first flow stabilizer 1 is made of iron or stainless steel, a small section of the first input section 11 with different calibers can be welded at the front end interface of the first connecting section 13, and a small section of the first output section 12 with different calibers can be welded at the rear end interface of the first connecting section 13, or the first input section 11 and the first output section 12 with different calibers can be directly welded together, so that the flow stabilizer can achieve a flow stabilization effect.

[0047] Specifically, the length of the first input section 11 and the length of the first output section 12 are both smaller than the length of the first connecting section 13;

[0048] The length of the second input section 21 and the length of the second output section 22 are both smaller than the length of the second connecting section 23 .

[0049] Preferably, a joint 6 is further included, and the joint 6 is arranged on the water outlet end of the first output section 12 and / or the water inlet end of the second input section 21 .

[0050] Furthermore, an internal thread is provided on the inner wall of the connector 6, and an external thread is provided on the water inlet end and / or the water outlet end of the water meter 3, and the internal thread and the external thread are threadedly connected to connect the connector 6 to the water inlet end and / or the water outlet end of the water meter 3.

[0051] Specifically, the connector 6 is movably disposed on the water outlet end of the first output section 12 and / or the water inlet end of the second input section 21 .
