[0029] A ball valve is a valve that controls the flow of fluid by rotating a sphere. The main features of a ball valve are simple structure, reliable sealing, light operation, and convenient maintenance. It is widely used in fluid control systems in various fields. The V-type ball valve is an improvement based on the traditional ball valve. Its sphere bottom is designed in a V shape, which can better control the flow rate and flow volume of the fluid, is suitable for handling viscous and fibrous materials, reduces the risk of blockage of the valve during operation, and is applicable to fluid control under harsh working conditions such as high temperature, high pressure, and strong corrosion.

[0030] The V-type ball valve in the related technology includes a ball valve body. First connection plates and second connection plates are respectively fixedly connected to both ends of the ball valve body. A connection block is fixedly connected to the top of the ball valve body. A connection screw rod passes through and is threadedly connected to the top of the connection block. One end of the connection screw rod is fixedly connected to a connection handle, and the other end of the connection handle passes through the ball valve body and is fixedly connected to a connecting rod, which can close the ball valve with a slipping thread to improve the use effect. However, under small flow conditions, the valve adjustment effect fails to meet the expectations and cannot achieve the purpose of high-precision small flow adjustment.

[0031] Based on this, to improve the problem of poor high-precision adjustment under small flow conditions in the related technology, the embodiments of the present application provide the following solutions.

[0032] Please refer to Figure 1 and Figure 3 simultaneously. The embodiments of the present application provide a small-incision high-precision V-type ball valve, which includes a housing 1, a sealing ring 3, a ball core 4, and a rotating mechanism 2. A liquid inlet 11, a liquid outlet 12, and a placement cavity 13 are provided on the housing 1. The ball core 4 is rotatably connected in the placement cavity 13. A V-shaped incision and a liquid through hole are provided on the ball core 4. The sealing ring 3 is arranged in the housing 1, and one end of the sealing ring 3 abuts against the housing 1, and the other end abuts against the center of the ball. The rotating mechanism 2 is arranged on the housing 1 for driving the ball core 4 to rotate and simultaneously controlling the rotation angle of the ball core 4.

[0033] In some embodiments, please refer to Figure 1 and Figure 4 simultaneously. The rotating mechanism 2 includes a rotating shaft 21, a rotating handle 22, a sealing sleeve 24, a sealing ring 25, an adjusting component 26, and a fixing component 23. The sealing sleeve 24 is threadedly connected to the housing 1. One end of the rotating shaft 21 passes through the sealing ring 25 and is fixedly connected to the center of the ball. The rotating handle 22 is fixedly connected to the other end of the rotating shaft 21. The sealing ring 25 is sleeved on the rotating shaft 21, and one end of the sealing ring 25 abuts against the sealing sleeve 24, and the other end of the sealing ring 25 abuts against the rotating shaft 21.

[0034] Set up like this, the sealing ring 3 is sleeved on the transmission shaft to fix the position of the rotating shaft 21. The fixing assembly 23 fixes the rotating handle 22 on the rotating shaft 21. After the liquid enters from the liquid inlet 11, when it is necessary to change the liquid flow rate, adjust the rotating handle 22. The rotating handle 22 will drive the rotating shaft 21 to rotate together. The other end of the rotating shaft 21 is connected to the ball core 4, and then drives the ball core 4 to rotate, so as to realize the opening and closing control of the ball core 4. At the same time, pay attention to observing the adjusting assembly 26, so that the rotating handle 22 reaches the preset position, and the liquid flows out from the liquid outlet 12, so as to realize the precise control of the liquid flow rate. At the same time, the sealing sleeve 24 and the sealing ring 25 prevent the liquid from overflowing from the inside of the housing 1 and prevent the device from being corroded due to liquid leakage.

[0035] In some embodiments, please refer to Figure 1 together. The adjusting assembly 26 includes a sliding ring 261, an adjusting disk 262 and adjusting teeth 263. The sliding ring 261 is slidably connected to the rotating handle 22. The adjusting teeth 263 are bonded to the sliding ring 261. The adjusting disk 262 is fixedly connected to the housing 1, and a plurality of grooves are formed on the adjusting disk 262.

[0036] Set up like this, there are scales on the adjusting disk 262, and different scales represent different opening and closing degrees of the ball core 4. When it is necessary to control the liquid flow rate, pull the sliding ring 261 upward along the direction of the rotating handle 22. At this time, the adjusting teeth 263 leave the adjusting disk 262. Adjust the rotating handle to the target position, and push the sliding ring 261 downward to make the adjusting teeth 263 snap into the grooves of the adjusting disk 262. In this way, the rotating handle is fixed and will not be easily rotated, ensuring the stability of the device.

[0037] Optionally, in some embodiments, please refer to Figure 2 together. The adjusting assembly 26 further includes a first limiting plate 264, a second limiting plate 265 and a rotating plate 266. The first limiting plate 264 and the second limiting plate 265 are both fixedly connected to the housing 1. The rotating plate 266 is bonded to one end of the rotating handle 22 close to the rotating shaft 21.

[0038] Set up like this, adjust the rotating handle until the ball core 4 is completely closed, the rotating plate 266 abuts against the second limiting plate 265, adjust the rotating handle until the ball core 4 is completely closed, the rotating plate 266 abuts against the first limiting plate 264, and make the rotating handle rotate within a limited angle, only allowing the liquid to pass through the V-shaped notch. Since the flow characteristic of the V-shaped ball valve is approximately equal percentage, this makes the adjustment process more convenient.

[0039] Optionally, in some embodiments, please refer to Figure 2 、 Figure 3 and Figure 4, the fixing component 23 includes a fixing nut 231 and a gasket 232. One end of the rotating shaft 21 away from the ball core 4 is provided with a thread, and the fixing nut 231 is threadedly connected to the threaded end of the rotating shaft 21. The gasket 232 is sleeved on the rotating shaft 21. One side of the gasket 232 abuts against the rotating handle 22, and the other side of the gasket 232 abuts against the fixing nut 231.

[0040] With such a setting, first, the rotating handle 22 is sleeved on one end of the rotating shaft 21 away from the ball core 4, then the washer is added, and then the fixing nut 231 is screwed and tightened. By using the pressure and the friction between the washer and the rotating handle 22, the rotating handle 22 is firmly fixed on the rotating shaft 21.

[0041] Optionally, in some embodiments, please refer to Figure 4 , a protective sleeve 221 is further sleeved on the rotating handle 22.

[0042] With such a setting, the protective sleeve 221 prevents people from being injured during use. At the same time, the rotating direction of the ball valve switch is marked on the protective sleeve 221.

[0043] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
