[0025] In the description of the present utility model, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0026] The following further describes the present utility model in detail with reference to embodiments:

[0027] As Figures 1-6 shown, the present utility model provides a stainless steel sphere valve, including a valve box 1, a connecting pipe 6, a valve ball installation pipe 7, and a metering valve ball 8. The top of the inner wall of the valve box 1 is fixedly connected to the top of the valve ball installation pipe 7. A guide pipe 2 is fixedly connected to the top of the valve box 1 above the valve ball installation pipe 7. A moving permanent magnet block 11 is slidably connected to the inner wall of the guide pipe 2. The center of the upper surface of the moving permanent magnet block 11 is fixedly connected to a pressing column 3. A fixing and adjusting assembly for fixing and adjusting its position is arranged on one side of the pressing column 3. The valve box 1, the guide pipe 2, and the valve ball installation pipe 7 are all made of stainless steel.

[0028] The bottom of the quantitative valve ball 8 is fixedly connected to a valve ball return spring 9 , and the bottom end of the valve ball return spring 9 is fixedly connected to a spring mounting seat 10 located at the bottom of the valve box 1 .

[0029] The internal part of the quantitative valve ball 8 is fixedly connected with an internal permanent magnet block 15 which repels the magnetic poles of the mobile permanent magnet block 11. The upper surface of the internal permanent magnet block 15 is parallel to the bottom surface of the mobile permanent magnet block 11. The mobile permanent magnet block 11 and the internal permanent magnet block 15 are neodymium iron boron magnets.

[0030] like Figures 1-6 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the fixed adjustment component includes a side mounting cylinder 12 fixed to the top of the guide tube 2, a limit column 4 movably connected to the inner wall of the side mounting cylinder 12, and a limit spring 13 sleeved on the outer wall of the limit column 4, and one end of the limit column 4 close to the pressure column 3 is fixedly connected with a positioning block 14, and a limiting hole 5 is opened on the side of the pressure column 3 close to the limit column 4.

[0031] One end of the positioning block 14 is plugged into the inner wall of the limiting hole 5 , and one side of the positioning block 14 close to the limiting hole 5 is in an arc shape, and the arc surface is connected to the adjacent surface of the positioning block 14 through a smooth transition.

[0032] One end of the limiting spring 13 overlaps with the side of the positioning block 14 close to the limiting column 4, and the other end of the limiting spring 13 overlaps with the inner wall of one end of the side mounting tube 12. When the pressure column 3 is pressed to move downward, since the side of the positioning block 14 that docks with the limiting hole 5 is in an arc state, the pressure column 3 will push the positioning block 14 to move toward the position of the side mounting tube 12 when it moves downward. When the pressure column 3 moves down to the position where the other limiting hole 5 docks with the positioning block 14, the positioning block 14 will be reset and inserted into the limiting hole 5 under the action of the deformation elastic force of the limiting spring 13, completing the fixation of the position of the pressure column 3, thereby fixing the position of the quantitative valve ball 8.

[0033] When the pressure column 3 needs to be lifted up, the limiting column 4 needs to be pulled to make the positioning block 14 disengage from the limiting hole 5. Then, after the pressure column 3 is lifted up to the specified position, the limiting column 4 is released, and the positioning block 14 will be reinserted into the corresponding limiting hole 5 under the elastic force of the limiting spring 13.

[0034] The side mounting tube 12 is composed of a square tube and a cylindrical tube connected end to end. The inner wall of the square tube is movably connected to the outer wall of the positioning block 14 , and the inner wall of the cylindrical tube is movably connected to the outer wall of one end of the limiting column 4 .

[0035] The bottom end of the valve ball installation pipe 7 is fixedly connected with a guiding arc plate 16 for guiding the quantitative valve ball 8. The bottom end of the guiding arc plate 16 is fixedly connected with the inner wall bottom of the valve box 1. During the downward movement of the quantitative valve ball 8 inside the inner wall of the valve ball installation pipe 7, the guiding arc plate 16 provides guidance and limitation for the downward movement of the quantitative valve ball 8, so that the quantitative valve ball 8 always moves up and down along a vertical path with respect to the bottom surface of the valve box 1. At the same time, positioning blocks can also be installed on the side of the quantitative valve ball 8 to limit the movement path of the quantitative valve ball 8 and prevent it from deflecting.

[0036] The valve box 1 and the guiding pipe 2 are in a non-connected state.

[0037] Next, the working principle of this stainless steel ball valve will be specifically described.

[0038] As Figures 1-6 shown, during use, the user presses the pressure application column 3. During the downward movement of the pressure application column 3 in the guiding pipe 2, it will drive the moving permanent magnet block 11 to move downward. During the downward movement of the moving permanent magnet block 11, since its magnetic pole repels the built-in permanent magnet block 15 in the quantitative valve ball 8, it will push the quantitative valve ball 8 in the inner wall of the valve ball installation pipe 7 to move downward under the action of magnetic force. When the quantitative valve ball 8 moves downward, it will compress the valve ball return spring 9. Conversely, when the pressure application column 3 pulls the moving permanent magnet block 11 upward, the quantitative valve ball 8 will be pushed upward under the elastic force of the valve ball return spring 9. When the quantitative valve ball 8 moves downward to the maximum position, it will form a closed state for the valve box 1.

[0039] Therefore, the lifting of the quantitative valve ball 8 can be controlled by the lifting of the pressure application column 3, thereby realizing the control of the flow rate size and the opening and closing of the flow.

[0040] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
