However, the invention still has defects such as a relatively complex structure, high cost, and inability to position without drive adjustment. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a positioning ball valve. To achieve the above purpose, the present invention provides the following technical solutions: a positioning ball valve, characterized in that it includes a valve body, a valve ball, a valve stem, a valve cover, a valve handle, and a rotating wheel, wherein the valve body has an outflow port and an inflow port, the valve ball is installed in the valve body, the valve ball has a conducting hole, and the flow rate is controlled by the rotation of the valve ball, one end of the valve stem is connected to the valve ball, and the other end passes through the valve cover to connect to the valve handle, and the valve handle is provided with a positioning groove; the valve cover is connected to the valve body, the valve cover has a plurality of slots, the rotating wheel is provided on the valve body, and one end of the fixing rod is connected to the rotating wheel in rotation; the other end of the fixing rod is installed in the positioning groove, and the fixing rod is rotated to be stuck in the slot to position the rotating wheel and the valve handle.

[0004] As a further improvement of the utility model,

[0005] It also has a latch, and the positioning groove has a through slide rail that cooperates with the latch on the fixing rod. When the positioning groove is engaged with the fixing rod, the latch is inserted into the slide rail.

[0020] The beneficial effects of the utility model are:

[0021] Since a rotating wheel is used and a fixing rod is provided on the rotating wheel, when the valve handle rotates to drive the valve ball, the valve handle also drives the fixing rod to rotate. At this time, when the fixing rod is still in the slot, the valve handle is prevented from rotating. When the fixing rod is out of the slot, the rotation of the valve handle will also drive the rotating wheel to rotate. When the valve handle rotates to a required angle, the fixing rod is pushed back and inserted into the slot to complete the positioning of the valve handle. The use of a rotating wheel to connect one end of the fixing rod makes the positioning of the fixing rod more secure. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0029] Embodiment 1:

[0030] Reference Figure 1 , 2 As shown in Figure 3, a positioning ball valve of this embodiment is characterized in that it includes a valve body 1, a valve ball 2, a valve stem 3, a valve cover 4, a valve handle 5, a rotating wheel 6, and a conducting hole 7. The valve body 1 is filled with the valve ball 2, and the valve ball 2 has the conducting hole 7. One end of the valve stem 3 is connected to the valve ball 2, and the other end passes through the valve cover 4 to connect to the valve handle 5. The valve cover 4 is connected to the valve body 1, and the valve handle 5 controls the rotation of the valve ball 2. The valve handle 5 is provided with a positioning groove 8, and the valve cover 4 has a plurality of clamping grooves 9. The rotating wheel 6 is rotatably connected to the valve body 1, and a fixing rod 10 is rotatably connected to the rotating wheel 6; the end of the fixing rod 10 facing away from the rotating wheel 6 is slidably connected to the positioning groove 8, and the fixing rod 10 is used to be clamped into the clamping groove 9.

[0031] Through the above technical solution, when the conducting hole 7 of the valve ball 2 passes through the liquid, in order to control the flow rate, the valve handle 5 and the rotary wheel 6 need to be rotated. At this time, the fixed rod 10 is rotated and disengaged from the slot 9. The valve handle 5 and the rotary wheel 6 rotate at the same time. When they are rotated to a certain angle, the conducting hole 7 is partially in contact with the valve body 1, so that the liquid flow rate increases or decreases. It is necessary to control the valve handle 5 to be positioned at this angle, and the rotating positioning rod is inserted into the slot 9 so that the valve handle 5 and the rotary wheel 6 cannot move, thereby completing the positioning of the valve handle 5 and the rotary wheel 6. The rotary hole 25 is connected to the fixed rod 10, and the rotary rod 26 is rotated into the rotary hole 25 to make the fixed rod 10 rotate around the rotary hole 25 as the axis.

[0032] As an improved specific implementation method, the fixing rod 10 is provided with a latch 11, and the positioning groove 8 has a through slide rail 12. When the fixing rod 10 is inserted into the positioning groove 8, the latch 11 is slidably connected to the slide rail 12. The rotating wheel 6 and the fixing rod 10 also have a through rotating hole 25, and a rotating rod 26 is provided in the rotating hole 25 for fixing one end of the fixing rod 10.

[0033] According to the above technical solution, since the positioning groove 8 will rotate when the fixing rod 10 is installed, it is easy to get out of the positioning groove 8 when rotating. Therefore, a slide rail 12 along the rotation trajectory of the fixing rod 10 is punched on the positioning groove 8. When the fixing rod 10 is installed in the positioning groove 8, the pin 11 is inserted into the slide rail 12 to limit the fixing rod 10, so that the fixing rod 10 moves along the rotation trajectory and cannot get out of the positioning groove 8.

[0034] Embodiment 2:

[0035] Reference Figure 4 , 5 As shown, a positioning ball valve of this embodiment is characterized in that it includes a valve body 1, a valve ball 2, a valve stem 3, a valve cover 4, a valve handle 5, and a runner 6. The valve ball 2 is installed in the valve body 1, one end of the valve stem 3 is connected to the valve ball 2, and the other end passes through the valve cover 4 to connect the valve handle 5, the valve cover 4 is connected to the valve body 1, the valve handle 5 is provided with a positioning groove 8, the valve cover 4 has a plurality of slots 9, the runner 6 is arranged at the lower end of the valve cover 4, and the runner 6 is rotatably connected to one end of a fixing rod 10; the other end of the fixing rod 10 is installed in the positioning groove 8, and the fixing rod 10 is rotated to snap into the slot 9 to position the runner 6 and the valve handle 5, a connecting rod 13 is arranged in the valve ball 2, and a rolling sleeve 14 is provided on the connecting rod 13, and a brush head 15 is arranged on the rolling sleeve 14, and the brush head 15 contacts the inner wall of the valve ball 2.

[0036] Through the above technical solution, when the valve ball 2 is rotated to increase the area of ​​the conducting hole 7, the flow rate in the valve is also increased, and a connecting rod 13 is arranged in the valve, and the roller sleeve 14 and the brush head 15 on the connecting rod 13 will be driven by the fluid to rotate to clean the inner wall. While the flow rate is increased, the inside of the valve is more fully flushed, thereby keeping the valve less silted and ensuring the circulation of the liquid in the valve.

[0037] As an improved specific implementation, there is also a collecting tank 16 , and the collecting tank 16 is connected to the valve body 1 .

[0038] Through the above technical solution, when the valve handle 5 and the wheel 6 are rotated to control the conducting hole 7 to become smaller, the flow rate and flow velocity of the liquid also decrease at the same time. At this time, the rotation speed of the brush head 15 and the roller sleeve 14 decreases, and the impurities in the valve body 1 cannot be stirred. When a part of the impurities settle, they will flow into the collection tank 16, so that the impurities cannot affect the inside of the valve, thereby ensuring the smooth flow of the valve body 1.

[0039] As an improved specific implementation, a collecting hole 17 is provided on the valve ball 2 , and the collecting hole 17 is communicated with the collecting tank 16 .

[0040] Through the above technical solution, when the fluid passes through, a part of the impurities in the collecting groove 16 will be brought out into the valve body 1. At this time, a collecting hole 17 is set on the valve ball 2, so that the impurities need to flow back through the collecting hole 17 first and enter the collecting groove 16, so as to further limit the impurities.

[0041] As an improved specific implementation, the inlet of the collecting tank 16 has a flange 18 extending toward the inside of the collecting tank 16 .

[0042] Through the above technical solution, when impurities leave the collecting tank 16, they will be resisted by the flange 18 and will not be easily carried away by the fluid.

[0043] As an improved specific implementation, the collecting groove 16 has an external thread 19, and the valve body 1 has an internal thread 20 that matches the external thread 19. When the internal and external threads 19 are screwed, the collecting groove 16 is fixed to the valve body 1.

[0044] Through the above technical solution, the connection between the collecting tank 16 and the valve body 1 can be loosened by twisting the collecting tank 16, and it is more convenient to disassemble and clear the silt.

[0045] As an improved specific implementation, a sealing rubber ring 21 is provided between the collecting tank 16 and the valve body 1 .

[0046] Through the above technical solution, the sealing rubber ring 21 is arranged so that the collecting tank 16 and the valve body 1 are more tightly connected after connection, thereby preventing fluid leakage.

[0047] As an improved specific implementation, the valve body 1 has a first threaded hole 23 ; the valve cover 4 has a second threaded hole 27 , and a bolt 24 is screwed into the first threaded hole 23 and the second threaded hole 27 .

[0048] Through the above technical solution, the valve body 1 and the valve cover 4 are connected tightly by bolts screwed into the first and second threaded holes, and the bolts 24 are convenient and easy to obtain.

[0049] In summary,

[0050] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
