Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This application provides a V-type ball valve with multi-position adjustable opening, solving the problem that traditional ball valves typically employ single-position or continuously adjustable structures. Single-position ball valves have a fixed opening degree and cannot flexibly adapt to the flow requirements of different working conditions; while continuously adjustable ball valves, although capable of stepless adjustment, suffer from the following drawbacks: insufficient adjustment accuracy, complex structure, and poor stability.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] This utility model discloses a V-type ball valve with multiple adjustable positions.

[0028] According to the appendix Figures 1-4 As shown, it includes a valve body unit 1 and a rotating unit 2 disposed on the valve body unit 1. The valve body unit 1 includes a valve body 11, a V-shaped valve core 12 and a valve stem 13. The V-shaped valve core 12 and the valve stem 13 are rotatably disposed on the valve body 11, and the top end of the valve stem 13 extends outward and is fixedly connected to a handle 14.

[0029] Rotating unit 2 includes:

[0030] The arc-shaped strip 21 is fixedly installed on the top of the valve body 11, and multiple positioning holes 211 can be selectively opened on the outer side of the arc-shaped strip 21.

[0031] The sliding block 22 is fixedly installed below the end of the handle 14, and the sliding block 22 is provided with a limiting pin 23 that can be inserted into the positioning hole 211. The valve stem 13 can be fixed at a preset angle by using the limiting pin 23 in conjunction with the positioning hole 211.

[0032] An arc-shaped strip 21 is fixed to the top of the valve body 11 and is distributed in an arc shape along the rotation trajectory of the valve stem 13. Multiple positioning holes 211 are opened on the outer side of the arc-shaped strip 21, each corresponding to a preset valve opening position. Simultaneously, a sliding block 22 is fixed below the end of the handle 14 and rotates synchronously with the handle 14. A limiting pin 23 passes through the sliding block 22 and can be inserted into the positioning hole 211. When the limiting pin 23 is inserted into different positioning holes 211, the valve stem 13 is locked at the corresponding angle, achieving a fixed opening. The mechanical limiting structure is wear-resistant and vibration-resistant, ensuring the stability of the valve position during long-term use.

[0033] Furthermore, a valve seat is fixedly installed inside the valve body 11, and the outer side of the valve seat V-shaped valve core 12 is fitted with it, and the bottom end of the valve stem 13 is fixedly connected to the V-shaped valve core 12.

[0034] Furthermore, the sliding block 22 has an internal slot, the limiting pin 23 passes through the sliding block 22, and the limiting pin 23 is fixedly connected to the outer side of the limiting ring 24, which is slidably connected to the inner wall of the slot.

[0035] Furthermore, a limiting spring 25 is movably sleeved on the outer side of the limiting pin 23, and the two ends of the limiting spring 25 are respectively fixedly connected to the side of the limiting ring 24 and the inner wall of the slot.

[0036] An arc-shaped strip 21 is fixedly installed on the top of the valve body 11, and multiple positioning holes 211 are provided on its outer side. These positioning holes 211 provide multiple preset angle positions for fixing the valve stem 13. A sliding block 22 is fixedly installed below the end of the handle 14, and has an internal slot for installing and accommodating the limit pin 23 and related components. The limit pin 23 passes through the sliding block 22 and can be inserted into the positioning hole 211. Through the cooperation with the positioning hole 211, the valve stem 13 is fixed at a preset angle. A limit ring 24 is fixedly connected to the outer side of the limit pin 23 and slidably connected to the inner wall of the slot, which serves to limit the range of movement of the limit pin 23 and guide it.

[0037] The limiting spring 25 is movably sleeved on the outside of the limiting pin 23, and its two ends are fixedly connected to the side of the limiting ring 24 and the inner wall of the slot, respectively. The limiting spring 25 provides elastic force so that the limiting pin 23 remains inserted into the positioning hole 211 when no external force is applied, or can automatically spring back under the action of external force.

[0038] Furthermore, a fixing rod 26 is fixedly connected to the top of the valve body 11, and the two fixing rods 26 are fixedly connected to both ends of the arc-shaped strip 21. The fixing rods 26 are fixedly connected to the top of the valve body 11 and to both ends of the arc-shaped strip 21, providing support and fixation for the arc-shaped strip 21.

[0039] Furthermore, the end of the handle 14 is positioned between the two fixed rods 26.

[0040] Furthermore, a protective strip 27 is fixedly connected between the two fixed rods 26. The protective strip 27 is fixedly connected between the two fixed rods 26 to play a protective role, preventing the operator from accidentally contacting the moving parts and ensuring operational safety.

[0041] When the valve opening needs to be adjusted, the operator pulls the limit pin 23 outward, causing it to disengage from the positioning hole 211. At this time, the limit spring 25 is compressed. Then, the handle 14 is turned, causing the valve stem 13 and the V-shaped valve core 12 to rotate. When the desired opening is reached, the limit pin 23 is released. Under the elastic force of the limit spring 25, the limit pin 23 automatically inserts into the corresponding positioning hole 211, fixing the valve stem 13 at the preset angle, thereby achieving precise adjustment of the valve opening.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
