Description

Technical Field

[0001] This utility model relates to valve body technology, and more particularly to a three-way valve body structure. Background Technology

[0002] Valves are industrial devices used for the transmission and isolation of gases or liquids. In current applications, manual or automatic valves are generally used to control the flow of media within pipelines.

[0003] However, in industrial production, the pressure of some media changes over time, making it difficult for the original pipelines to transport the media. Or, the high pressure can lead to increased flow velocity and impact force, posing certain production risks. Therefore, a valve body structure that can automatically reduce pressure is needed. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model proposes a three-way valve body structure.

[0005] A three-way valve body structure includes a valve body, which is composed of a main pipe, a main branch pipe, a branch pipe and an installation pipe. A main flow channel is formed in the middle of the main pipe, a first branch flow channel is formed in the middle of the main branch pipe, and a second branch flow channel is formed in the middle of the branch pipe. The main flow channel, the first branch flow channel and the second branch flow channel are connected to each other.

[0006] The installation pipe is equipped with an elastic element and a sealing element. Under normal circumstances, the elastic element pushes the sealing element to block the second branch channel. The main branch pipe and the branch pipe are both connected to the installation pipe. The installation pipe extends from the outside of the main body to the main channel.

[0007] In this three-way valve body structure of the present invention, the inner diameter of the first diversion channel is smaller than the inner diameter of the second diversion channel.

[0008] In this three-way valve body structure of the present invention, a manifold is formed in the middle of the mounting tube, and the sealing element and elastic element are disposed in the manifold. The manifold is connected to the main flow channel, the first branch flow channel and the second branch flow channel.

[0009] In this three-way valve body structure of the present invention, the outer wall of the mounting tube is provided with a through hole, the through hole is connected to the manifold hole, and the end of the mounting tube inserted into the main channel forms a connection hole between the inner wall of the main channel and the connection hole connects the main channel and the manifold hole.

[0010] In this three-way valve body structure of the present invention, the sealing element is provided with a recessed opening and a positioning hole, the elastic element is located in the positioning hole, and the recessed opening is connected to the connecting hole.

[0011] In this three-way valve body structure of the present invention, the elastic element is a spring.

[0012] The three-way valve body structure of this utility model has the following beneficial effects: By opening a through hole and a connecting hole on the mounting pipe, the medium entering the connecting hole can push the sealing element under greater pressure, keeping the sealing element compressed against the elastic element. This allows the second branch channel to connect with the main channel. The second branch channel traps a portion of the medium, reducing the pressure in the main channel and thus avoiding the problem of excessively high flow velocity and impact force in the first branch channel. Simultaneously, the recessed opening on the sealing element can cooperate with the connecting hole, reducing the movement stroke of the sealing element, maintaining stable pressure and flow velocity in the first branch channel, and reducing the occurrence of adverse factors.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figures 1 to 4 As shown, this utility model's three-way valve body structure includes a valve body 1, which consists of a main pipe 2, a main branch pipe 3, a branch pipe 4, and an installation pipe 5. The main branch pipe 3 is aligned with the center line of the main pipe 2, while the center line of the branch pipe 4 is inclined to the center line of the main pipe 2, ensuring that the branch pipe 4 is a branch of the main pipe 2. This allows the second branch pipe 4 to automatically intercept a portion of the medium when the internal pressure of the main pipe 2 is high. After the medium pressure inside the main pipe 2 stabilizes, it works with the elastic element 6 to push the sealing element 7 upward, thereby ensuring a smooth flow of medium between the main flow channel 8 and the first branch channel 9.

[0019] A main channel 8 is formed in the middle of the main pipe 2, a first branch channel 9 is formed in the middle of the main branch pipe 3, and a second branch channel 10 is formed in the middle of the branch pipe 4. The main channel 8, the first branch channel 9, and the second branch channel 10 are connected. Meanwhile, the installation pipe 5 is equipped with an elastic element 6 and a sealing element 7. The elastic element 6 is a spring. Under normal conditions, the elastic element 6 pushes the sealing element 7 to block the second branch channel 10. Both the main branch pipe 3 and the branch pipe 4 are connected to the installation pipe 5, which extends from the outside of the main pipe 2 into the main channel 8.

[0020] The mounting tube 5 is equipped with a sealing disc 51 to achieve a seal and to abut against the elastic element 6.

[0021] A manifold 11 is formed in the middle of the mounting pipe 5. The mounting pipe 5 is inclined on the main body 2 and extends into the interior, keeping the first branch pipe 4 and the second branch pipe 4 connected to the mounting pipe 5. The sealing element 7 and the elastic element 6 are disposed in the manifold 11, which is connected to the main channel 8, the first branch channel 9 and the second branch channel 10.

[0022] The inner diameter of the first diversion channel 9 is smaller than that of the second diversion channel 10, which limits the amount of medium that can be discharged from the first diversion channel 9. It needs to work with the second diversion channel 10 to intercept the medium after the pressure inside the main channel 8 increases.

[0023] A through hole 12 is provided on the outer wall of the mounting tube 5. The through hole 12 is connected to the manifold 11. A connecting hole 13 is formed between the end of the mounting tube 5 inserted into the main channel 8 and the inner wall of the main channel 8. The connecting hole 13 connects the main channel 8 and the manifold 11.

[0024] Furthermore, the through hole 12 does not coincide with the center line of the first diversion channel 9, keeping the through hole 12 at the lower end of the first diversion channel 9, thereby preventing the medium discharged from the main channel 8 from directly reaching the first diversion channel 9. In addition, with the blocking effect of the elastic element 6, the flow rate of the medium can be reduced, allowing it to be transported smoothly.

[0025] The seal 7 has a recessed opening 14 and a positioning hole 15. The elastic element 6 is located inside the positioning hole 15, and the recessed opening 14 is connected to the connecting hole 13. The recessed opening 14 is located at the position of the connecting hole 13, which can ensure that when the pressure of the medium inside the main channel 8 increases, it will immediately push the seal 7 with the connection hole 13. In addition, the recessed opening 14 can also reduce the distance between the medium and the second diversion channel 10, ensuring that when the pressure in the main channel 8 increases, the medium can immediately push the seal 7 through the recessed opening 14 to compress the elastic element 6, so that the second diversion channel 10 can intercept a part of the medium and discharge it.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
