[0025] The following will further describe the present application in detail Figures 1-4 in conjunction with the accompanying drawings.

[0026] The embodiment of the present application discloses a combined three-way ball valve. Referring to Figure 1 , a combined three-way ball valve includes a first three-way ball valve 1. A valve cover body 2 is detachably installed at the center of the upper surface of the first three-way ball valve 1. An adjusting rod 3 is detachably installed at the top end of the valve cover body 2. Three connecting pipes 4 are connected to the surface of the first three-way ball valve 1 in a triangular array. A sealing ring 5 is adhesively bonded to one side of the inner wall of the connecting pipe 4. An anti-detachment component 6 is detachably installed on the side wall of the connecting pipe 4. One end of the connecting pipe 4 is connected to a three-way steel pipe 7 through the sealing ring 5. One end of the connecting pipe 4 is connected to a second three-way ball valve 8 through the three-way steel pipe 7. A conventional ball valve 9 is connected to the back of the first three-way ball valve 1. The sealing ring 5 is made of a rubber component, and the inner wall of the sealing ring 5 is closely attached to one end of the three-way steel pipe 7.

[0027] When the three-way steel pipe 7 is connected to the three-way ball valve, both ends of the three-way steel pipe 7 will be respectively attached to the inner walls of two groups of sealing rings 5. Since the sealing ring 5 is made of a rubber component, it can avoid the phenomenon that there is a gap between the two connection parts when the three-way steel pipe 7 is connected to the three-way ball valve, thereby reducing losses.

[0028] The first three-way ball valve 1 and the second three-way ball valve 8 are controlled by the adjusting rod 3. The three-way steel pipe 7 is used as the feed pipe, and two conventional ball valves are used as the discharge pipes. The first three-way ball valve 1 and the second three-way ball valve 8 are opened simultaneously, and the flow rate distribution is achieved by controlling the opening degree. The first three-way ball valve 1 is opened and the second three-way ball valve 8 is closed; or the first three-way ball valve 1 is closed and the second three-way ball valve 8 is opened to achieve the flow direction switching. Two conventional ball valves are used as the feed pipes and the three-way steel pipe 7 is used as the discharge pipe. The first three-way ball valve 1 and the second three-way ball valve 8 are opened simultaneously to mix the medium. Multiple functions of the combined valve are realized.

[0029] Referring to Figures 2-4 , the anti-detachment assembly 6 includes a stable base 61 and a hydraulic telescopic rod 62. The side wall of the stable base 61 is fixedly connected with the hydraulic telescopic rod 62. The other side wall of the stable base 61 is connected to the side wall of the connecting pipe 4. The number of the stable bases 61 is four, and the four stable bases 61 are equally divided into two groups. One end of the hydraulic telescopic rod 62 is fixedly connected with a stable mounting ring 63. Two hydraulic lifting rods 64 are detachably mounted symmetrically along the center inside the stable mounting ring 63. The bottom end of the hydraulic lifting rod 64 is fixedly connected with an arc-shaped limiting plate 65. A plurality of stable suction cups 66 are fixedly connected to the lower surface of the arc-shaped limiting plate 65 in an arc array. The lower surface of the stable suction cup 66 is connected to one side of the surface of the three-way steel pipe 7. The number of the stable suction cups 66 is several, and the several stable suction cups 66 are equally divided into four groups. The extended length of the hydraulic telescopic rod 62 is less than the length of the three-way steel pipe 7, and the length of the hydraulic telescopic rod 62 is greater than the length of the hydraulic lifting rod 64.

[0030] The implementation principle of a combined three-way ball valve in an embodiment of this application is as follows: When the model of the three-way steel pipe 7 is smaller than the model at the connection of the three-way ball valve, first, both ends of the three-way steel pipe 7 are connected to the first three-way ball valve 1 and the second three-way ball valve 8 respectively through the anti-detachment assembly 6. Then, the hydraulic lifting rods 64 inside the two anti-detachment assemblies 6 are started to perform the lifting work. Immediately afterwards, the hydraulic lifting rods 64 will drive the two arc-shaped limiting plates 65 and the stable suction cups 66 to move until the lower surface of the stable suction cup 66 is attached to one side of the surface of the three-way steel pipe 7, which can ensure the stable connection between the first three-way ball valve 1 and the second three-way ball valve 8, thereby enhancing the practicability of the device.

[0031] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
