Description

Technical Field

[0001] The utility model relates to the technical field of four-way valves, in particular to a four-way joint with adjustable passages. Background Art

[0002] A four-way valve, also known as a four-way pipe joint, is a device used to connect four pipes, allowing fluid or media to flow in different directions. It is usually made of materials such as metal or plastic and has multiple inlet and outlet channels. A four-way pipe joint can divert fluid from one pipe to multiple pipes, or merge fluid from multiple pipes into one pipe as needed.

[0003] After the existing four-way pipe joints on the market are connected, the internal parts always remain interconnected. When the pipes connected to the four-way pipe joints need to be replaced, all four passages need to be closed at the same time to avoid leakage when replacing the pipes. However, closing all four pipes at the same time will affect the normal flow of other channels and the operation time is long. For this reason, we propose a four-way joint with adjustable passages. Utility Model Content

[0004] The purpose of the present utility model is to provide a four-way joint with adjustable passages to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0027] like Figure 1-4 As shown, the utility model provides a technical solution:

[0028] A four-way joint with adjustable passage, comprising a four-way joint body 1, a main joint 2 being provided at one end of the four-way joint body 1, an internal thread 3 being provided inside the main joint 2, and auxiliary joints 4 being integrally formed on the three sides of the four-way joint body 1 away from the main joint 2, both ends of the external surfaces of the auxiliary joints 4 being provided with external threads 5, a main through-groove 14 being provided between the connecting groove 9 and the main joint 2, and auxiliary through-grooves 15 being provided between the connecting groove 9 and the three auxiliary through-grooves 4, the main through-groove 14 and the auxiliary through-grooves 15 being both connected to the connecting groove 9, and the inner diameter of the main through-groove 14 being larger than the inner diameters of the three auxiliary through-grooves 15 , This device is provided with a main joint 2 at one end of the four-way joint body 1, and an internal thread 3 is provided inside the main joint 2. Three auxiliary joints 4 are integrally formed on the three sides of the four-way joint body 1 away from the main joint 2. There is no connection gap between the four-way joint body 1 and the main joint 2 and the three auxiliary joints 4. When connecting with the pump pipeline, the four-way joint body 1 is connected to the corresponding joint thread of the pump, and then the three hoses are respectively sleeved on the three auxiliary joints 4, and then tightened with a clamp. By reducing the connection gap and connection accessories, the installation amount and leakage points can be reduced;

[0029] like Figure 4 As shown, an adjusting chamber 6 is provided inside the four-way joint body 1 away from the main joint 2, and an adjusting disk 7 is movably installed inside the adjusting chamber 6. A telescopic slot 8 is provided on the inner side of one end of the middle of the adjusting disk 7, and connecting slots 9 are provided at both ends of the telescopic slot 8. A spring 10 is provided at one end of the telescopic slot 8 close to the axis of the adjusting disk 7, and a plug 11 is fixedly installed on the other end of the spring 10. The plug 11 is away from the end of the spring 10 and both ends. An inner groove 12 is provided, and a plug disk 13 is fixedly installed on the outside of the connection between the spring 10 and the plug 11. A sealing seat 17 is provided on the top of the four-way joint body 1 away from the main joint 2, and a rotating shaft 18 is movably installed inside the sealing seat 17. The bottom end of the rotating shaft 18 is fixedly connected to the axis of the adjusting disk 7. This device can adjust the four passages into an interconnected state, or close a single auxiliary slot 15. When the hose needs to be replaced, the auxiliary slot 15 at the corresponding position can be blocked. In this way, when replacing, the other two passages can be used normally, which will not affect the normal operation of the equipment, and there is no need to close all the pipelines.

[0030] like Figure 3 As shown, an annular groove 16 is formed in an annular manner between the external threads 5 at both ends of the three auxiliary connectors 4. The diameter of the annular groove 16 is larger than the inner diameter of the auxiliary connector 4 and smaller than the outer diameter of the auxiliary connector 4. In this device, an annular groove 16 is formed in the middle of the three auxiliary connectors 4. When the auxiliary connector 4 is sleeved with the external hose, the clamp is clamped to the outside of the hose, and then the clamp is tightened. The clamp will gradually be retracted into the auxiliary groove 15, so that it is not easy to loosen after tightening.

[0031] like Figure 3As shown, a slot 19 is provided on one side of the top of the shaft 18. The surface of the slot 19 is horizontal. When adjusting, the shaft 18 can be twisted with a tool or a knob can be sleeved on the shaft 18.

[0032] Working principle: When adjusting, the control shaft 18 rotates and drives the adjusting disk 7 to rotate 90 degrees, rotating the plug 11 from the position of the main through slot 14 to the auxiliary through slot 15 on one side, so that the liquid or gas entering the main through slot 14 will enter the other two auxiliary through slots 15 from the adjusting chamber 6, and at the same time enter the telescopic slot 8 along the connecting slot 9, and the spring 10 in the telescopic slot 8 will control the plugging disk 13 and the plugging disk 11 to block the auxiliary through slot 15 at this position, and the liquid or gas entering the telescopic slot 8 will enter the other two auxiliary through slots 15 from the plugging disk 13. The back of the plug 11 is pressurized, and the greater the pressure applied to the back of the plug 13, the higher the sealing performance of the plug 11 and the plug 13. When the four passages need to be kept fully open, the plug 11 is rotated to the position of the main through groove 14. At this time, after the main through groove 14 is pressurized, the plug 11 drives the plug 13 to retreat and compresses the spring 10. In this way, the liquid in the main through groove 14 will pass through the inner groove 12 in the plug 11 into the telescopic groove 8, and then flow into the regulating chamber 6 along the connecting groove 9. In this state, the four passages remain interconnected.

[0033] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
