Description

Technical Field

[0001] This utility model belongs to the field of three-way valve technology, specifically a three-way valve for pipelines. Background Technology

[0002] Three-way valves for pipelines are key control components in fluid transport systems. They enable fluid diversion, merging, or reversal through three ports, allowing complex fluid path switching to be completed with a single valve, significantly improving system efficiency and reducing installation costs.

[0003] In existing three-way valves, the three pipes on the valve are connected to an external pipeline and bolted together. An internal ball valve is used to regulate the switching between the three pipes to achieve fluid transport. However, in the current three-way valve installation, because the valve body length is fixed, if the external pipeline is too short, other pipes cannot be connected to the external pipeline, which is not conducive to the operator's installation. At the same time, the connection may also lead to a reduction in sealing performance. Therefore, it needs to be improved. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a three-way valve for pipelines.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a three-way valve for pipelines, comprising a three-way valve, a pipeline structure provided on the outside of the three-way valve, a sleeve assembly sleeved on the outer surface of the pipeline structure, and a reinforcing component provided inside the sleeve assembly;

[0006] The pipeline structure includes a connecting pipe, the outer surface of which is provided with a threaded groove, and the outer side of which is provided with a sliding groove.

[0007] The sleeve assembly includes an extension tube, the inner side of which is adapted to a threaded groove, and a retaining groove is provided on the outer side of the extension tube. The retaining grooves are evenly distributed around the extension tube, and a bolt is provided at the top of the extension tube, which is located in the retaining groove. The bottom of the bolt extends into the sliding groove.

[0008] Preferably, the bottom of the outer side of the bolt is relatively smooth, and the outer side of the bolt is movably connected to the inner wall of the groove.

[0009] Preferably, three of the pipeline structures and sleeve assemblies are provided, and the three pipeline structures and sleeve assemblies are respectively located outside the three-way valve.

[0010] Preferably, a sealing ring is provided inside the connecting pipe, and the top of the sealing ring is movably connected to the inner wall of the extension pipe.

[0011] Preferably, the reinforcing component includes a limiting rod, the outer side of which is connected to the inner wall of the connecting pipe.

[0012] Preferably, the outer surface of the limiting rod is provided with a pressure block located in the inner cavity of the sealing ring, and the outer side of the pressure block is movably connected to the inner cavity of the sealing ring.

[0013] Preferably, a second bolt is provided on the outside of the connecting pipe, and the inner side of the second bolt penetrates the connecting pipe and extends into the interior of the pressure block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model is equipped with a connecting pipe and an extension pipe. By rotating the first bolt, it is moved out of the groove, and then the extension pipe is rotated, causing the extension pipe to rotate on the outer surface of the connecting pipe. The length of the combination of the connecting pipe and the extension pipe is adjusted to extend the length of the pipeline. Then the first bolt is screwed back into the slot and locked in the groove. This allows the operator to adjust the length of the pipeline to avoid it being too short during installation, which would prevent it from being unable to connect to the pipeline, thus improving its practicality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Example 1

[0023] like Figures 1 to 4 As shown, this is the first embodiment of the utility model, which provides a three-way valve for pipelines, including a three-way valve 1, a pipeline structure 2 is provided on the outside of the three-way valve 1, a sleeve assembly 3 is sleeved on the outer surface of the pipeline structure 2, and a reinforcing assembly 4 is provided inside the sleeve assembly 3.

[0024] The pipeline structure 2 includes a connecting pipe 201, a threaded groove 202 is provided on the outer surface of the connecting pipe 201, and a sliding groove 203 is provided on the outer side of the connecting pipe 201.

[0025] The sleeve assembly 3 includes an extension tube 301. The inner side of the extension tube 301 is adapted to the threaded groove 202. A slot is provided on the outer side of the extension tube 301. The slots are evenly distributed around the extension tube 301. A bolt 302 located in the slot is provided at the top of the extension tube 301. The bottom of the bolt 302 extends into the sliding groove 203.

[0026] By rotating bolt 302, the bottom of bolt 302 is moved out of the groove 203, releasing the restriction on the extension pipe 301. Then, the extension pipe 301 is rotated to adjust its position on the connecting pipe 201. This makes it easier to extend or shorten the combined length of the connecting pipe 201 and the extension pipe 301. This avoids situations where the three-way valve 1 cannot be installed due to the shortness of the pipeline when connecting it to the pipeline, thus improving the practicality of the three-way valve 1 and bringing convenience to the operator.

[0027] Example 2

[0028] like Figure 2 and Figure 3 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the bottom of the outer side of bolt 302 is relatively smooth, and the outer side of bolt 302 is movably connected to the inner wall of the groove 203.

[0029] When bolt 302 is screwed into the groove 203, it limits the extension tube 301 as a whole, preventing the extension tube 301 from rotating after installation, which would cause the combined length of the connecting tube 201 and the extension tube 301 to change and lead to leakage.

[0030] Among them, there are three of each of the pipeline structure 2 and the sleeve assembly 3, and the three pipeline structures 2 and the sleeve assembly 3 are respectively located on the outside of the three-way valve 1;

[0031] The three-way valve 1 is adjusted in three directions by using three pipe structures 2 and sleeve assembly 3 to prevent improper installation of the pipes in the three directions.

[0032] The connecting pipe 201 is provided with a sealing ring 204 inside, and the top of the sealing ring 204 is movably connected to the inner wall of the extension pipe 301.

[0033] The sealing ring 204 is used to seal the gap at the connection between the connecting pipe 201 and the extension pipe 301, preventing fluid leakage from the connection and ensuring the normal operation of the three-way valve 1.

[0034] Example 3

[0035] like Figure 3 and Figure 4 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the reinforcing component 4 includes a limiting rod 401, and the outer side of the limiting rod 401 is connected to the inner wall of the connecting pipe 201.

[0036] Among them, the outer surface of the limiting rod 401 is provided with a pressure block 402 located in the inner cavity of the sealing ring 204, and the outer side of the pressure block 402 is movably connected to the inner cavity of the sealing ring 204.

[0037] The pressure block 402 is moved into the interior of the sealing ring 204 by the compression band, which further compresses the sealing ring 204, causing the sealing ring 204 to deform and move the sealing ring 204 to fit tightly against the inner wall of the extension tube 301, thereby improving the waterproof effect between the connecting tube 201 and the extension tube 301.

[0038] Among them, a bolt 403 is provided on the outside of the connecting pipe 201, and the inner side of the bolt 403 penetrates the connecting pipe 201 and extends into the interior of the pressure block 402.

[0039] By rotating bolt 403, the pressure block 402 is moved on the outer surface of the limit rod 401, causing it to press the pressure block 402 into the sealing ring 204, resulting in greater deformation of the sealing ring 204. At the same time, when adjusting the length between the connecting pipe 201 and the extension pipe 301, the rotation of the extension pipe 301 is made easier, avoiding excessive force.

[0040] Working principle and usage process of this utility model:

[0041] First, when the operator is installing the three-way valve 1 and encounters a situation where the pipeline is too short, rotating bolt 302 causes it to move out of the slide groove 203, releasing the restriction on the extension pipe 301. Then, rotating the extension pipe 301 moves it along the outer surface of the connecting pipe 201, connecting it to the pipeline to prevent misalignment. Once it reaches the appropriate position, rotating bolt 403 causes the pressure block 402 to move along the outer surface of the limit rod 401. The extension pipe 301 moves along the pipe, and the sealing ring 204 is squeezed by the pressure block 402. The sealing ring 204 deforms and is firmly attached to the inner wall of the extension pipe 301. Then, the bolt 302 is re-inserted into the slot on the outside of the slide groove 203, so that the extension pipe 301 is limited by the bolt 302 to prevent the extension pipe 301 from moving further and causing unstable connection. By adjusting the combined length of the connecting pipe 201 and the extension pipe 301, it is easy to connect between pipes that are too short, making it easier for operators to install.
