Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a multi-channel valve. Background Technology

[0002] In the field of fluid control, multi-channel valves are widely used in industries such as chemical, food, and pharmaceutical to achieve fluid diversion, merging, and switching control between different channels.

[0003] Traditional multi-channel valves, during long-term use, are prone to leakage due to the susceptibility of the sealing structure between the valve core and body to fluid erosion, wear, and media corrosion. This leakage not only wastes materials but can also lead to safety accidents, especially when conveying hazardous chemicals or high-purity fluids, where the consequences are even more severe. Furthermore, the operating mechanism of traditional valves is often poorly designed, resulting in complex operation and difficulty in achieving rapid and precise channel switching and flow control. For applications requiring frequent adjustments to fluid direction and flow, operators need to spend considerable time and effort, and the control precision is insufficient to meet the demands of modern industrial production.

The inner wall of sleeve 25 is threadedly connected to the outer arc wall of screw ring 21, allowing sleeve 25 to be fitted onto the first connecting pipe 22 and the second connecting pipe 23. Rotating sleeve 25 then fits onto screw ring 21, effectively securing the first connecting pipe 22 and the second connecting pipe 23. A first internally threaded cylinder 26 is embedded and fixedly connected to the lower end of the four-way valve body 1. A first externally threaded component 27 is embedded and threadedly connected inside the first internally threaded cylinder 26. A third sealing ring 28 is provided between the first internally threaded cylinder 26 and the first externally threaded component 27, allowing the first externally threaded component 27 to be embedded inside the first internally threaded cylinder 26 to seal the bottom of the four-way valve body 1. The channel functions as follows: A second internal threaded cylinder 30 is embedded and fixedly connected to the upper end of the four-way valve body 1. A second external threaded component 31 is embedded and threadedly connected inside the second internal threaded cylinder 30. A fourth sealing ring 29 is provided between the second internal threaded cylinder 30 and the second external threaded component 31, which can embed the second external threaded component 31 into the second internal threaded cylinder 30 and seal the top channel of the four-way valve body 1.

[0036] Working principle: By aligning the first connecting pipe 22 and the second connecting pipe 23 with both ends of the four-way valve body 1, and then fitting the rotating sleeve 25 onto the first connecting pipe 22 and the second connecting pipe 23, rotating the rotating sleeve 25 allows it to be fitted onto the threaded ring 21, thus installing and fixing the first connecting pipe 22 and the second connecting pipe 23. The rotating component 16 then engages with the valve stem 10 through a structure such as the square block 14 and the support plate 15. When the rotating component 16 is rotated, the trapezoidal arc plate 17 moves at both ends of the arc cover 18, allowing the valve stem 10 to rotate within 90 degrees. The rotation of the valve stem 10 also drives the ball valve 6 to rotate through the groove 7. The ball valve 6 rotates within the ball sleeve 2, aligning the channel on the ball valve 6 with the corresponding channel on the four-way valve body 1, allowing fluid to pass through. When multiple channels are needed, the connecting pipes can be connected to the first internal threaded cylinder 26 and the second internal threaded cylinder 30. When not needed, they can be sealed using the first external threaded component 27 and the second external threaded component 31.
