Description

Technical Field

[0001] This utility model relates to the field of valves, and in particular to an adjustable valve. Background Technology

[0002] A valve is a mechanical device that controls the flow rate, flow direction, pressure, temperature, etc. of a flowing fluid medium. Valves are basic components in pipeline systems. Valves can be operated manually or by handwheel, handle, or pedal. They can also be controlled to change the pressure, temperature, and flow rate of the fluid medium. Valves can perform continuous or repetitive operations on these changes.

[0003] Existing valves are often difficult to open and close, and the adjustment angle is not precise enough, requiring multiple people to operate them simultaneously. In addition, the flow control of fluids is not accurate enough, resulting in the problem that valves are difficult to use and cannot be precisely controlled. Utility Model Content

[0004] This invention provides an adjustable valve that solves the problems of laborious valve use and inaccurate valve control.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable valve includes a valve body with an inlet on the left side and an outlet on the right side. A valve core is disposed inside the valve body, and a valve stem is fixedly connected to the top of the valve core. A first handle is connected to the other end of the valve stem. The valve stem controls the opening and closing of the pipeline by controlling the valve core. The valve body also includes a protective tube for protecting the valve stem. An adjusting mechanism is provided on the protective tube, meshing with a first gear on the valve stem to adjust the rotation angle of the valve stem. The adjusting mechanism includes an adjusting shell, a gear assembly, and an adjusting component. The gear assembly includes a second gear, a third gear, a fourth gear, and a fifth gear fixedly installed along the axial direction of the first gear rod, and a fifth gear fixedly installed along the axial direction of the second gear rod. The first and second gear rods are rotatably connected to the adjusting shell. The adjusting component meshes with the gear assembly to adjust the rotation torque of the valve stem and adjust the valve core angle.

[0007] Furthermore, the adjustment mechanism engages with the first gear via a second gear located at one end of the first gear rod.

[0008] Furthermore, in the gear assembly, the fourth gear meshes with the fifth gear, and the adjustment assembly includes a sixth gear fixedly installed along the axial direction of the third gear rod and an adjustment chamber. The third gear rod is rotatably connected to the adjustment chamber, and the sixth gear is fixedly installed on the third gear rod. One end of the sixth gear extends out of the adjustment housing and is connected to the second handle. The sixth gear can mesh with the third gear and the fifth gear respectively through the adjustment chamber.

[0009] Furthermore, the adjustment chamber is provided with a limiting block fixedly installed on the third gear rod. The third gear rod is pushed to move within the adjustment chamber by the second handle to adjust the meshing position of the sixth gear and the gear assembly.

[0010] Furthermore, the first gear and the second gear are bevel gears, while the third gear, the fourth gear, the fifth gear, and the sixth gear are spur gears.

[0011] Furthermore, the first gear has the same number of teeth as the second gear, and the fourth gear has the same number of teeth as the fifth gear.

[0012] Furthermore, the gear ratio of the first gear, the second gear, the third gear, the fourth gear, the fifth gear, and the sixth gear is 1:1:2:1:1:1.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model is as follows:

[0014] 1. The first handle and the second handle can simultaneously adjust the rotation of the valve stem. The first handle is directly connected to the valve stem for large-angle adjustment of the valve core. The second handle can precisely adjust the valve stem through gear meshing. The two handles work together to achieve accurate control of the valve.

[0015] 2. By adjusting the meshing gears through the third and fourth gears with different numbers of teeth on the first gear rod, and further adjusted by the adjusting assembly, different torques can be applied when rotating the valve stem. This makes valve adjustment easier and less strenuous. This transmission ratio design allows the operator to adjust the valve stem rotation with appropriate force and angle changes when rotating the second handle, achieving precise adjustment of the valve core angle. Simultaneously, the meshing transmission between different gears ensures the smoothness of the adjustment process, avoiding jamming or impact, further improving the accuracy of the adjustment.

[0023] This utility model provides a self-cleaning valve, as per the attached instruction manual. Figures 1 to 3 It can be seen that,

[0024] Example 1

[0025] This embodiment is an example of an adjustable valve, specifically an adjustable valve including a valve body 1. The left side of the valve body 1 is connected to an inlet 2, and the right side is connected to an outlet 3. A valve core 4 is disposed inside the valve body 1, and a valve stem 5 is fixedly connected to the top of the valve core 4. The other end of the valve stem 5 is connected to a first handle 6. The valve stem 5 controls the opening and closing of the pipeline by controlling the valve core 4. The valve body 1 also includes a protective tube 7, which protects the valve stem 5. The protective tube 7 is fixedly connected to the valve body 1 by welding, ensuring sealing and stability, extending the service life of the valve stem 5, and ensuring the normal operation of the valve. An adjusting mechanism 8 is provided on the protective tube 7, which is fixed to the protective tube 7 by welding, ensuring the stability of the adjusting mechanism 8. The adjusting mechanism 8 meshes with a first gear 9 on the valve stem 5. The first gear 9 rotates synchronously with the valve stem 5 to adjust the rotation angle of the valve stem 5. By meshing with the first gear 9 on the valve stem 5, the rotation angle is precisely controlled, thereby achieving precise adjustment of the opening degree of the valve core 4 and improving the accuracy of the valve in controlling fluid flow. The regulating mechanism 8 includes an regulating housing 10, a gear assembly, and an regulating component 11. The gear assembly includes a second gear 122, a third gear 123, a fourth gear 124 fixedly mounted along the axial direction of the first gear rod 12, and a fifth gear 135 fixedly mounted along the axial direction of the second gear rod 13. The first gear rod 12 and the second gear rod 13 are rotatably connected to the regulating housing 10 and are connected to the regulating housing 10 via bearings, ensuring the fixed and rotatable connection of the gear rods. The arrangement of multiple gears can achieve different transmission ratios. Through the meshing combinations between different gears, multiple options are provided for the rotation of the regulating valve rod 5, increasing the flexibility of regulation. The regulating component 11 meshes with the gear assembly and is used to adjust the rotation torque of the valve rod 5 and adjust the valve core angle. It can not only adjust the rotation torque of the valve rod 5 to make operation more labor-saving or adjust the torque according to actual needs, but also further precisely adjust the valve core angle, thereby more accurately controlling the flow rate and pressure of the fluid.

[0026] Furthermore, the adjusting mechanism 8 meshes with the first gear 9 via a second gear 122 located at one end of the first gear rod 12. This ensures that power is transmitted from the adjusting mechanism 8 to the valve stem 5, thereby controlling the rotation of the valve stem 5, and the structure is simple and the transmission is stable.

[0027] Furthermore, in the gear assembly, the fourth gear 124 meshes with the fifth gear 135. The adjusting assembly 11 includes a sixth gear 146 fixedly mounted along the axial direction of the third gear rod 14 and an adjusting chamber 15. The third gear rod 14 is rotatably connected to the adjusting chamber 15, and the sixth gear 146 is fixedly mounted on the third gear rod 14. One end of the sixth gear 14 extends out of the adjusting housing 10 and is connected to the second handle 16. The sixth gear 146 can mesh with the third gear 123 and the fifth gear 135 respectively through the adjusting chamber 15. By meshing the sixth gear 146 with different gears, the transmission path and transmission ratio can be changed, thereby achieving different adjustment effects. The operator can easily achieve these adjustments by turning the second handle 16, which is convenient and quick.

[0028] Furthermore, the adjustment chamber 15 is equipped with a limiting block 151 fixedly mounted on the third gear rod 14. The third gear rod is moved within the adjustment chamber by the second handle 16 to adjust the meshing position of the sixth gear 146 with the gear assembly. By moving the third gear rod 14 by the second handle 16, the limiting block 151 in the adjustment chamber 15 can rotate, accurately controlling the meshing position of the sixth gear 146 with other gears. This ensures the meshing accuracy between gears, avoids misalignment or poor meshing, and improves the stability and reliability of the adjustment mechanism 8.

[0029] Furthermore, the first gear 9 and the second gear 122 are bevel gears, while the third gear 123, the fourth gear 124, the fifth gear 135, and the sixth gear 146 are spur gears. The bevel gears are used to achieve power transmission in different directions, enabling the adjusting mechanism 8 to be connected and driven by the valve stem 5 in a relatively compact structure; the spur gears have the characteristics of high transmission efficiency and high precision, ensuring the stability and accuracy of the entire gear transmission system.

[0030] Furthermore, the first gear 9 and the second gear 122 have the same number of teeth, and the fourth gear 124 and the fifth gear 135 have the same number of teeth. Gears with the same number of teeth can maintain the same speed and direction of rotation during transmission, making the adjustment process smoother and more precise.

[0031] Furthermore, the gear ratio of the first gear 9, the second gear 122, the third gear 123, the fourth gear 124, the fifth gear 135, and the sixth gear 146 is 1:1:2:1:1:1. This specific gear ratio design allows for precise adjustment of the rotation angle and torque of the valve stem 5, meeting the requirements for valve flow control under different operating conditions.
