[0024] It is generally used in conjunction with fluid pipelines to switch the open and closed states of fluid flow within the pipeline;
[0025] A strip-shaped guide groove 81 is formed on the end face of the tubular body 1 near the sphere 2. One end of a movable pin 82 is embedded in the strip-shaped guide groove 81 and connected to the bottom surface of the strip-shaped guide groove 81 by a first spring 9. The other end of the movable pin 82 can extend out of the end face of the tubular body 1 under the action of the first spring 9. A push pin 10 is movably provided between the end of the rotating handle 4 connected to the sphere 2 and the movable pin 82 that can move along the axial direction of the tubular body 1. An arc-shaped push surface 42 is formed on the rotatable rotating handle 4, which slides in contact with one end of the push pin 10. The distance between the arc-shaped push surface 42, which extends over at least a quarter circumference, and the rotation center of the rotating handle 4 gradually changes in its extension direction. The push pin 10 A second spring 11 is provided between the side opposite to the rotating handle 4 and the tubular body 1, so that one end of the push pin 10 is always in contact with the arc-shaped push surface 42 on the rotating handle 4 under the action of the second spring 11 in the compression state. An annular relief groove 12 is provided on the side wall of the movable pin 82, which slides in contact with the inner wall of the strip guide groove 81. When the movable pin 82 is pushed into the strip guide groove 81 and the ball 2 rotates to the 90° position with the rotating handle 4, the other end of the push pin 10 is embedded in the annular relief groove 12. When the ball 2 rotates to the 0° position with the rotating handle 4, the two ends of the push pin 10 are in contact with the side wall of the movable pin 82 and the arc-shaped push surface 42 respectively, and the end of the movable pin 82 opposite to the first spring 9 extends out of the end face of the tubular body 1.
[0026] When the flow channel needs to be switched from the closed state to the open state, firstly, the movable pin needs to be pressed into the strip guide groove to move the movable pin towards the first spring and squeeze the first spring until the annular clearance groove on the movable pin is aligned with the push pin. Then, drive the rotating handle to rotate the ball from the 0° position to the 90° position. At the 0° position, the distance H1 between the arc-shaped push surface on the rotating handle and the abutment position of the push pin and the rotation center of the rotating handle is less than the distance H2 between the arc-shaped push surface on the rotating handle and the abutment position of the push pin and the rotation center of the rotating handle at the 90° position. During the rotation of the rotating handle, the push pin gradually moves towards the movable pin under the action of the arc-shaped push surface on the rotating handle until its end is embedded in the strip guide groove on the movable pin. At the 90° position, the direction of the flow channel through hole on the ball is parallel to the axis of the tubular body, and the internal flow channels of the tubular body located on both sides of the ball are connected through the flow channel through hole on the ball, and the flow channel is opened.
[0027] The end faces of both ends of the aforementioned push pin 10 are convex arc-shaped surfaces; the two opposite side walls of the aforementioned annular relief groove 12 are set as sloping surfaces that cooperate with the end faces of the push pin 10.
[0028] An annular pushing groove 13, which is connected to the annular relief groove 12 and has a depth less than the annular relief groove 12, is provided on the movable pin 82 and located on the side of the annular relief groove 12 near the first spring 9. When the ball 2 rotates to the 0° position with the rotating handle 4, one end of the push pin 10 abuts against the bottom surface of the annular pushing groove 13. The side wall of the annular pushing groove 13 away from the annular relief groove 12 is set as a slope surface that matches the end face of the push pin 10.
[0029] The end of the rotating handle 4 connected to the ball 2 has a protrusion 41 that extends radially into the tubular body 1. One end of the protrusion 41, which is connected to the ball 2 by a bolt, is embedded in the ball 2.
[0030] Example 2: A high-flow-rate valve unit includes: a tubular body 1, a sphere 2 rotatably disposed inside the tubular body 1, and a flow channel through hole 3 extending in a direction perpendicular to its rotation axis on the sphere 2, which can rotate around one of its diameter directions; one end of a rotating handle 4 disposed on the outside of the tubular body 1 is connected to the sphere 2 and used to drive the sphere 2 to rotate; when the sphere 2 rotates to the 0° position with the rotating handle 4, the direction of the flow channel through hole 3 on the sphere 2 is perpendicular to the axial direction of the tubular body 1 and the outer circumferential surface of the sphere 2 is sealed to the inner wall of the tubular body 1; when the sphere 2 rotates to the 90° position with the rotating handle 4, the direction of the flow channel through hole 3 on the sphere 2 is parallel to the axial direction of the tubular body 1 and the internal flow channels of the tubular body 1 located on both sides of the sphere 2 are connected through the flow channel through hole 3 on the sphere 2.
[0031] A strip-shaped guide groove 81 is formed on the end face of the tubular body 1 near the sphere 2. One end of a movable pin 82 is embedded in the strip-shaped guide groove 81 and connected to the bottom surface of the strip-shaped guide groove 81 by a first spring 9. The other end of the movable pin 82 can extend out of the end face of the tubular body 1 under the action of the first spring 9. A push pin 10 is movably provided between the end of the rotating handle 4 connected to the sphere 2 and the movable pin 82 that can move along the axial direction of the tubular body 1. An arc-shaped push surface 42 is formed on the rotatable rotating handle 4, which slides in contact with one end of the push pin 10. The distance between the arc-shaped push surface 42, which extends over at least a quarter circumference, and the rotation center of the rotating handle 4 gradually changes in its extension direction. The push pin 10 A second spring 11 is provided between the side opposite to the rotating handle 4 and the tubular body 1, so that one end of the push pin 10 is always in contact with the arc-shaped push surface 42 on the rotating handle 4 under the action of the second spring 11 in the compression state. An annular relief groove 12 is provided on the side wall of the movable pin 82, which slides in contact with the inner wall of the strip guide groove 81. When the movable pin 82 is pushed into the strip guide groove 81 and the ball 2 rotates to the 90° position with the rotating handle 4, the other end of the push pin 10 is embedded in the annular relief groove 12. When the ball 2 rotates to the 0° position with the rotating handle 4, the two ends of the push pin 10 are in contact with the side wall of the movable pin 82 and the arc-shaped push surface 42 respectively, and the end of the movable pin 82 opposite to the first spring 9 extends out of the end face of the tubular body 1.
[0032] When the flow channel needs to be switched from the open state to the closed state, the rotating handle needs to be driven to rotate, causing the sphere to rotate from the 90° position to the 0° position. During this process, the push pin remains in contact with the arc-shaped push surface under the action of the second spring, causing the push pin to move away from the movable pin shaft along with the arc-shaped push surface, thus being pulled out from the strip guide groove on the movable pin shaft. At the same time, the movable pin shaft, no longer restricted by the push pin, resets under the action of the first spring, causing one end of it to extend out of the end face of the tubular body and its outer wall to press against one end of the push pin. The other end of the push pin presses against the arc-shaped push surface on the rotating handle, thus limiting the rotation handle and preventing the rotating handle from rotating due to misoperation or accidental contact. At the 0° position, the direction of the flow channel through hole on the sphere is perpendicular to the axis of the tubular body, and the outer circumferential surface of the sphere is sealed with the inner wall of the tubular body, thus closing the flow channel.
[0033] A protrusion 101 is formed on the side wall of the push pin 10, which extends radially outward. The second spring 11 is disposed between the protrusion 101 and the tubular body 1. Grooves for the two ends of the second spring 11 are respectively provided on the protrusion 101 and the tubular body 1.
[0034] A sealing ring 5 is provided between the inner wall of at least one end of the tubular body 1 and the outer circumferential surface of the sphere 2; a first annular flange 61 with an inner diameter smaller than the diameter of the sphere 2 is provided on the inner wall of at least one end of the tubular body 1, and a second annular flange 62 with a radially inward direction is provided on the inner wall of the first annular flange 61, and the sealing ring 5 is provided between the second annular flange 62 and the sphere 2.
[0035] A sealing ring is provided between the protrusion 41 that rotatably engages with the tubular body 1 and the tubular body 1; the sphere 2 is connected to the inner wall of the tubular body 1 on the side opposite to the rotating handle 4 via a rotating shaft 7.
[0036] The working principle of this utility model is as follows:
[0037] It is generally used in conjunction with fluid pipelines to switch the open and closed states of fluid flow within the pipeline;
[0038] When the flow channel needs to be switched from the closed state to the open state, firstly, the movable pin needs to be pressed into the strip guide groove to move the movable pin towards the first spring and squeeze the first spring until the annular clearance groove on the movable pin is aligned with the push pin. Then, drive the rotating handle to rotate the ball from the 0° position to the 90° position. At the 0° position, the distance H1 between the arc-shaped push surface on the rotating handle and the push pin and the rotation center of the rotating handle is less than the distance H2 between the arc-shaped push surface on the rotating handle and the push pin and the rotation center of the rotating handle at the 90° position. During the rotation of the rotating handle, the push pin gradually moves towards the movable pin under the action of the arc-shaped push surface on the rotating handle until its end is embedded in the strip guide groove on the movable pin. At the 90° position, the direction of the flow channel through hole on the ball is parallel to the axis of the tubular body, and the internal flow channels of the tubular body located on both sides of the ball are connected through the flow channel through hole on the ball, and the flow channel is opened.
[0039] When the flow channel needs to be switched from the open state to the closed state, the rotating handle needs to be driven to rotate, causing the sphere to rotate from the 90° position to the 0° position. During this process, the push pin remains in contact with the arc-shaped push surface under the action of the second spring, causing the push pin to move away from the movable pin shaft along with the arc-shaped push surface, thus being pulled out from the strip guide groove on the movable pin shaft. At the same time, the movable pin shaft, no longer restricted by the push pin, resets under the action of the first spring, causing one end of it to extend out of the end face of the tubular body and its outer wall to press against one end of the push pin. The other end of the push pin presses against the arc-shaped push surface on the rotating handle, thus limiting the rotation handle and preventing the rotating handle from rotating due to misoperation or accidental contact. At the 0° position, the direction of the flow channel through hole on the sphere is perpendicular to the axis of the tubular body, and the outer circumferential surface of the sphere is sealed with the inner wall of the tubular body, thus closing the flow channel.
[0040] When using the above-mentioned high-flow-rate valve unit, it can quickly open and close the high-flow-rate fluid channel, and ensure the stability of the fluid channel when it is closed, avoiding abnormal opening of the flow channel due to misoperation or accidental contact, and ensuring safety during use.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
