[0021] Embodiment 1

[0022] See also Figures 1 to 4 A water supply valve with a floating ball 20 that is easy to adjust includes a valve body 10, a driving rod 31, a transmission rod 32, an adjusting rod 40 and a floating ball 20. The driving rod 31 is connected to a valve core 11 inside the valve body 10. Both ends of the transmission rod 32 are respectively connected to the adjusting rod 40 and the driving rod 31. The floating ball 20 is fixedly arranged at the end of the adjusting rod 40. The floating ball 20 is placed inside a liquid container. When the liquid level in the container rises or falls, the floating ball 20 moves up and down, driving the adjusting rod 40 and the transmission rod 32 to swing in turn. The swing of the transmission rod 32 drives the driving rod 31 to move, and then drives the valve core 11 to move in the valve body 10, so as to adjust the opening of the valve body 10. The valve body 10 passes liquid into the liquid container or stops passing liquid, thereby controlling the liquid level. An adjusting disk 34 is fixedly provided at the end of the transmission rod 32, and the adjusting rod 40 is rotatably connected to the center of the adjusting disk 34. The adjusting rod 40 can be rotated to change the angle between the adjusting rod 40 and the transmission rod 32. A fixing part 50 is provided on the adjusting rod 40, and the fixing part 50 is used to fix the adjusted adjusting rod 40 and the transmission rod 32. The accuracy of the liquid level controlled by the valve body 10 can be adjusted by changing the angle between the adjusting rod 40 and the transmission rod 32.

[0023] An inlet flow channel 101 and an outlet flow channel 102 are arranged inside the valve body 10. The inlet flow channel 101 and the outlet flow channel 102 are intersected and connected. Liquid enters the valve body 10 from the inlet flow channel 101 and is discharged from the outlet flow channel 102. A valve core 11 is arranged inside the valve body 10. The valve core 11 can move inside the valve body 10 to change the intersection area between the inlet flow channel 101 and the outlet flow channel 102, thereby controlling the flow rate of liquid discharged from the valve body 10 and further controlling the liquid level height of the container.

[0024] The inlet channel 101 is perpendicular to the outlet channel 102. The outlet channel 102 is located below the inlet channel 101. The inlet channel 101 is horizontally arranged. The driving rod 31 is inserted into the inlet channel 101 and is parallel to the inlet channel 101. The driving rod 31 passes through the side wall of the valve body 10. A sealing member is provided at the connection between the valve body 10 and the driving rod 31 to ensure the sealing of the valve body 10 during the movement of the driving rod 31. A support rod 33 is provided on the outside of the valve body 10, and the middle part of the transmission rod 32 is rotatably connected to the support rod 33. A shaft sleeve 311 is provided at one end of the driving rod 31 located on the outside of the valve body 10. The shaft sleeve 311 is vertically arranged, and one end of the driving rod 32 is bent and inserted in the shaft sleeve 311. A limiting nut 321 is also provided on the driving rod 32. When the driving rod 32 is inserted in the shaft sleeve 311, the limiting nut 321 is located above the shaft sleeve 311 to limit the displacement of the driving rod 32 and prevent the driving rod 32 from detaching from the bottom of the shaft sleeve 311 during the movement of the driving rod 31. The other end of the driving rod 32 is connected to the adjusting rod 40 through the adjusting disk 34; when the float 20 moves up and down with the change of the liquid level, the adjusting rod 40 moves as a whole, thereby driving the driving rod 32 to rotate, and the driving rod 32 pushes the driving rod 31 to move in the inlet flow channel 101, thereby changing the opening of the valve body 10 and controlling the flow of the valve body 10.

[0025] The adjusting disk 34 is fixedly arranged at the end of the transmission rod 32. The adjusting disk 34 is in the shape of a circular plate and is provided with positioning grooves 341. A plurality of positioning grooves 341 are evenly spaced around the adjusting disk 34. The adjusting rod 40 is rotatably connected to the center of the adjusting disk 34. By rotating the adjusting rod 40 around the center of the adjusting disk 34, the angle between the adjusting rod 40 and the transmission rod 32 can be changed, thereby changing the height and accuracy of the liquid level controlled by the valve body 10.

[0026] Preferably, a scale is provided on the adjustment disk 34 , and the scale is arranged around the adjustment disk 34 for a whole circle. The scale is marked with angles, and the rotation angle of the adjustment rod 40 can be confirmed by the scale on the adjustment disk 34 , thereby determining the angle between the adjustment rod 40 and the transmission rod 32 .

[0027] In the present application, the adjusting rod 40 is relatively long so that when the valve body 10 is installed, the float 20 is located inside the liquid container, and the end of the adjusting rod 40 can extend to the outside of the liquid container, so that the operator can rotate the adjusting rod 40 through the end of the adjusting rod 40 outside the liquid container, thereby changing the angle between the adjusting rod 40 and the transmission rod 32.

[0028] See also Figure 3 The fixing member 50 is arranged on the adjusting rod 40, and includes a connecting rod 51, a buckle 52 and an operating part 53. The operating part 53 and the buckle 52 are respectively located at both ends of the connecting rod 51. The buckle 52 is arranged at the end of the connecting rod 51. The connecting rod 51 can move relative to the adjusting rod 40 to drive the buckle 52 to move, so that the buckle 52 is inserted into the positioning groove 341 to fix the adjusting rod 40 and the adjusting disk 34.

[0029] In this embodiment, the positioning groove 341 is disposed on the end surface of the adjusting disk 34, with the center of the adjusting disk 34 as the center point, and the centers of the positioning grooves 341 are located on a circle with a radius, such as Figure 2 As shown, a support 41 is provided on the adjusting rod 40, a connecting rod 51 is provided above the adjusting rod 40 and is rotatably connected to the support 41, a buckle 52 and an operating part 53 are respectively located on both sides of the support 41, and the operating part 53 is close to the end of the adjusting rod 40, and is located outside the liquid container together with the end of the adjusting rod 40. Under the action of the buckle 52's own weight, the buckle 52 moves downward and is inserted into the positioning groove 341 to fix the adjusting disk 34 and the adjusting rod 40; when the adjusting rod 40 needs to be adjusted, the operating part 53 is pressed downward, the connecting rod 51 rotates relative to the support 41, and the buckle 52 moves upward to disengage from the positioning groove 341. At this time, there is no limit between the adjusting rod 40 and the adjusting disk 34, and the adjusting rod 40 can rotate relative to the adjusting disk 34 to change the angle between the adjusting rod 40 and the transmission rod 32.

[0030] A shell 42 is fixedly set on the adjusting rod 40, and the shell 42 is hollow inside. The end of the adjusting rod 40 and the end of the connecting rod 51 are both arranged in the shell 42. A fixing groove is set on the top side wall of the shell 42, and the fixing groove runs through the side wall of the shell 42. The cross-section of the operating part 53 is trapezoidal, and a hook bent toward the adjusting rod 40 is set on it; when the buckle 52 moves downward and is inserted into the positioning groove 341, the operating part 53 moves upward, and the hook is stuck in the side of the fixing groove during the upward movement of the operating part 53, connecting the operating part 53 with the fixing groove, so that the buckle 52 is stably maintained in the state of being inserted into the positioning groove 341.

[0031] Furthermore, in order to ensure that the buckle 52 is stably inserted in the positioning groove 341, a spring 54 is also provided on the adjusting rod 40. The spring 54 is arranged perpendicular to the adjusting rod 40, and the spring 54 corresponds to the operating part 53. The two ends of the spring 54 are respectively fixedly connected to the connecting rod 51 and the adjusting rod 40, and are always in a compressed state, so that when the operating part 53 moves upward to the highest point, the spring 54 can provide thrust for the operating part 53 to keep the operating part 53 at the highest point. The spring 54 applies pressure to the buckle 52 through the connecting rod 51, presses the buckle 52 into the positioning groove 341, and keeps it inserted in the positioning groove 341, so as to prevent the buckle 52 from escaping from the positioning groove 341, and stably connect the adjusting rod 40 and the adjusting disk 34.

[0032] Taking lowering the highest liquid level in the liquid container (that is, when the liquid level is at a lower height, the valve body 10 is closed to stop water discharge) as an example, the specific adjustment method is to press the operating part 53 to rotate the connecting rod 51, and the buckle 52 rises and separates from the positioning groove 341, keep pressing the operating part 53, and rotate the end of the adjusting rod 40 upward to lower the float 20, increase the angle between the adjusting rod 40 and the transmission rod 32, and after confirming the angle between the adjusting rod 40 and the transmission rod 32 with the scale on the corresponding adjusting disk 34, release the operating part 53, and under the elastic force of the spring 54, the operating part 53 rises, the connecting rod 51 rotates to make the buckle 52 downward, and the buckle 52 is pressed into the positioning groove 341 to complete the adjustment.

[0033] Embodiment 2

[0034] See also Figure 4 , which is different from the first embodiment in that the moving mode of the fixing member 50 is different. In this embodiment, the positioning grooves 341 are arranged on the circumferential surface of the adjusting disk 34, and the positioning grooves 341 are arranged evenly spaced. A slide groove is arranged on the top surface of the adjusting rod 40, and the slide groove is arranged along the length direction of the adjusting rod 40. The connecting rod 51 is inserted into the slide groove, and the connecting rod 51 can slide along the slide groove, so as to insert the buckle 52 into the positioning groove 341. The operating part 53 is provided with a boss protruding outward, so that the operator can hold it and drive the connecting rod 51 to move through the boss; correspondingly, the housing 42 is provided with a slide groove for the ball to move.

[0035] The specific operation method is that when adjustment is needed, hold the boss and move the boss upward along the adjusting rod 40 to disengage the buckle 52 from the positioning groove 341, and keep the boss position unchanged, rotate the adjusting rod 40 corresponding to the scale on the adjusting disk 34, change the angle between the adjusting rod 40 and the transmission rod 32, and after determining the angle, move the boss downward along the adjusting rod 40 to reinsert the buckle 52 into another positioning groove 341 to fix the adjusting rod 40 and the transmission rod 32.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
