Technical Field

[0001] The utility model relates to the field of channel joints, in particular to a multi-channel joint. Background Technique

[0002] A multi-channel joint, also known as a multi-way joint or a multi-port joint, is a connecting device that can simultaneously transmit multiple fluids or gases. It usually consists of a main body and multiple independent channels, and each channel has its own sealing and connection mechanism, which can be respectively connected to different pipelines or devices.

[0003] Most of the existing channel joints still adopt the single-channel joint design. During the gas switching process of the actuator, the single-channel design can only support the gas to enter from one channel and then discharge from another channel. However, in the operation of the actuator that requires frequent or rapid gas path switching, due to the limitations of the single-channel joint design, it can often only adapt to specific sizes and types of pipelines, resulting in increased installation complexity and cost, and it is difficult to achieve precise control of the gas.

[0004] In view of the above problems, it is necessary to design a multi-channel joint for multi-path transmission of gases. Content of the Utility Model

[0005] In order to overcome the limitations of the single-channel joint design, which can often only adapt to specific sizes and types of pipelines, resulting in increased installation complexity and cost, the utility model provides a multi-channel joint.

[0006] The technical solution of the utility model is: a multi-channel joint, including a threaded end, a joint main body and a first connection end pipe. The threaded end is sleeved on the lower part of the joint main body, and the first connection end pipe is installed at the rear side of the joint main body. It also includes an outer ring channel, an inner ring channel and a second connection end pipe. The outer ring channel is arranged at the inner rear side of the joint main body, and the outer ring channel is communicated with the first connection end pipe. The inner ring channel is arranged in the middle of the joint main body, and the second connection end pipe is connected to the front side of the joint main body, and the second connection end pipe is communicated with the inner ring channel.

[0007] As a further preferred solution, a circular groove is arranged at the bottom of the joint main body, a clamping groove is arranged in the middle of the inner side wall of the circular groove, and a protruding part adapted to the clamping groove is arranged on the outer side of the upper part of the threaded end. The protruding part is in the shape of a frustum of a cone that gradually expands from top to bottom.

[0008] As a further preferred solution, a vent hole is arranged in the middle of the threaded end, the vent hole is communicated with the outer ring channel, and the lower end of the joint main body penetrates through the vent hole.

[0009] As a further preferred solution, a passage for gas to flow is arranged between the outer wall of the lower part of the joint main body and the inner wall of the vent hole.

[0010] As a further preferred solution, it further includes a sealing ring, and the sealing ring is sleeved on the outer side of the lower part of the joint body.

[0011] As a further preferred solution, it further includes a rubber ring, and the rubber ring is arranged on the outer side of the upper part of the threaded end.

[0012] As a further preferred solution, any one of a ferrule joint, a flare fitting or a quick-connect fitting can be adopted for the first connection end pipe and the second connection end pipe to meet different connection requirements.

[0013] As a further preferred solution, the joint body is selected from one of a T-shaped, an F-shaped or a Y-shaped as its structural form.

The threaded end 1 is sleeved on the lower part of the joint body 2. An air guide hole 8 is provided in the middle of the threaded end 1, and the air guide hole 8 is communicated with the outer ring channel 7 for gas flow. The lower end of the joint body 2 penetrates through the air guide hole 8. A circular groove 21 is provided at the bottom of the joint body 2. A clamping groove 22 is provided in the middle of the inner side wall of the circular groove 21. An protruding portion adapted to the clamping groove 22 is provided on the outer side of the upper part of the threaded end 1. The protruding portion is in the shape of a frustum of a cone that gradually expands from top to bottom. When the upper part of the threaded end 1 is inserted into the circular groove 21, the protruding portion is clamped into the clamping groove 22 to connect the threaded end 1 and the joint body 2. A passage for gas flow is provided between the outer wall of the lower part of the joint body 2 and the inner wall of the air guide hole 8. The first connection end pipe 3 is installed at the rear side of the joint body 2. The outer ring channel 7 is provided at the rear side inside the joint body 2. The outer ring channel 7 is respectively communicated with the first connection end pipe 3 and the air guide hole 8. Gas can be conducted through the passage of the air guide hole 8 and the outer ring channel 7 to facilitate gas flow. An inner ring channel 10 is provided in the middle of the joint body 2. The second connection end pipe 12 is connected to the front side of the joint body 2. The second connection end pipe 12 is communicated with the inner ring channel 10, so that gas can flow into the second connection end pipe 12 through the inner ring channel 10. A sealing ring 13 is sleeved on the outer side of the lower part of the joint body 2 to enhance the sealing performance at the connection between the joint body 2 and the actuator 14. A rubber ring 15 is provided on the outer side of the upper part of the threaded end 1 to improve the sealing performance at the connection between the threaded end 1 and the joint body 2. The first connection end pipe 3 and the second connection end pipe 12 can adopt any one of a ferrule joint 4, a flare fitting 5, or a quick-connect fitting 6 to adapt to different connection requirements and application scenarios. The joint body 2 selects one of a T-shaped, an F-shaped, or a Y-shaped as its structural form. A spiral thread interface matching the actuator 14 is provided on the outer side of the lower end of the threaded end 1 to directly connect to the actuator 14. The actuator 14 and the threaded end 1 are hermetically connected through a thread sealant to ensure the sealing performance and safety of the gas channel.

[0024] When it is necessary to use the device to switch the gas channel to control the operation of the actuator 14, the staff should select one of the T-type, F-type or Y-type as the structural form of the connector according to the specific application scenario. If the application scenario is suitable for the T-type structural form of the connector, the staff will put the threaded end 1 under the T-type connector.

After the two pagoda joints 5 are connected, the actuator 14 The air inlet pipe and the air outlet pipe are respectively connected to the other ends of the two pagoda joints 5 to ensure the smooth flow of gas. The gas enters the air guide hole 8 through the air inlet pipe of the actuator 14, so that the gas is evenly distributed in the air guide hole 8, and then flows smoothly into the outer ring channel 7, and is guided to the first terminal pipe 3 along the outer ring channel 7. Then the gas flows into the inside of the pagoda joint 5 through the first terminal pipe 3, and then flows from the pagoda joint 5 into the air outlet pipe of the actuator 14, and pushes the actuator 14 to move, completing the first path transmission of the gas and realizing the first action of the actuator 14. When it is necessary to switch to another gas transmission path When changing the direction of movement of the actuator 14 or stopping the movement of the actuator 14, the gas enters another pagoda joint 5 through the outlet pipe of the actuator 14, and then enters the open channel of the second end pipe 12 through another pagoda joint 5, and then smoothly enters the inner circle channel 10 from the open channel of the second end pipe 12. The gas flows in the inner circle channel 10 and then flows to the inlet pipe of the actuator 14, pushing the reverse movement of the actuator 14, completing the second path transmission of the gas, realizing the retraction or stop of the actuator 14, and meeting the flexible control requirements for different action paths of the actuator 14.
