[0040] The working principle of the utility model is as follows:

[0041] Generally, the utility model is used in cooperation with a fluid pipe and is used for switching the opening and closing state of fluid circulation in the pipe;

[0042] When it is needed to switch the flow channel from the closed state to the open state, firstly, the movable pin shaft is pressed into the strip-shaped guide groove to make the movable pin shaft move to the spring direction and press the spring until the annular allowance groove on the movable pin shaft is aligned with the push pin, then the rotating handle is driven to rotate to make the sphere rotating with it rotate from the 0° position to the 90° position, the distance H1 between the contact position of the strip-shaped groove on the driving ring and the convex strip part on the push pin and the rotating center of the driving ring at the 0° position is smaller than the distance H2 between the contact position of the strip-shaped groove on the driving ring and the convex strip part on the push pin and the rotating center of the driving ring at the 90° position; in the rotating process of the rotating handle, the push pin gradually moves to the movable pin shaft direction under the action of the strip-shaped groove on the driving ring until the end part of the push pin is embedded into the strip-shaped guide groove on the movable pin shaft; the direction of the flow channel through hole on the sphere at the 90° position is parallel to the axial direction of the tubular body and the internal flow channels of the tubular body on both sides of the sphere are communicated through the flow channel through hole on the sphere, and the flow channel is opened.

[0043] 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 ball to rotate from the 90° position to the 0° position. During this process, the push pin also moves away from the movable pin shaft under the action of the strip groove on the drive ring, 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, is reset under the action of the spring, so that one end of it extends out of the end face of the tubular body and its outer wall presses against one end of the push pin to limit the rotating handle, preventing the rotating handle from rotating due to misoperation or accidental contact. The direction of the flow channel through hole on the ball at the 0° position is perpendicular to the axis of the tubular body, and the outer circumferential surface of the ball is sealed with the inner wall of the tubular body, thus closing the flow channel.

[0044] When using the above-mentioned liquid-cooled valve connector, it can quickly open and close the high-flow fluid channel, and ensure the stability of the fluid channel when it is closed. This avoids abnormal opening of the flow channel due to misoperation or accidental contact, ensuring safety during use, and also facilitates the replacement of vulnerable parts.

[0045] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. 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.
