By adopting the above technical solution, when the fluid is flowing in the valve tube in the positive direction, the fluid will impact the check plate and make the check plate rotate in the direction of the return spring. Then the check plate will not prevent the rotation of the fluid, leaving the valve tube in communication In this process, the non-return plate will squeeze the arc-shaped plate and then squeeze the return spring. The return spring allows the arc-shaped plate to always squeeze the non-return plate. After the fluid in the valve tube is reduced, the non-return plate will be squeezed against the arc-shaped plate.

In addition, the extrusion plate is set in an arc shape to increase The scope of the squeeze plate is to clamp more shapes of workpieces. The setting of the rubber block increases the friction of the squeeze plate, and the sliding motor can drive the gear to rotate around its own axis line. Because the gear is in the fixed frame, it is restricted by the fixed frame and can only move along the length of the fixed frame. After the sliding motor is activated, the sliding plate will move along the length of the fixed frame, so that the sliding plate has the ability to move and realize the purpose of adjusting the hydraulic clamp station. The lifting hydraulic cylinder can drive the squeezing hydraulic cylinder to move up and down to drive the two squeezing plates to move up and down, so as to realize the purpose of moving up and down the hydraulic fixture station. The rotating motor can drive the extrusion plate to rotate, so that the relative angle between the extrusion plate and the sliding plate can be adjusted, and the adjustment of the extrusion plate can adapt to the workpiece and better clamp the workpiece. The translational hydraulic cylinder can drive the fixed frame to move, thereby driving the squeeze plate to move, so as to realize the translational purpose of the hydraulic clamp. When the sides of the two extrusion plates abut against each other, the extrusion plate and the adjacent extrusion hydraulic cylinder are at the maximum distance at this time. At this time, the extrusion plate is easy to tilt toward the sliding plate due to the action of gravity. The time tilt rod can support the extruded plate and prevent the extruded plate from tilting.

Because some dead corners are not easy to clean, it is easy to clean with a flushing tube with water pressure. In addition, a fixed tube is provided to reduce the volume of water sprayed from the flushing tube, thereby increasing the water pressure of the flushing tube and enhancing the strength of the water pressure. , In addition, the setting of the fixed pipe makes the water sprayed by the flushing pipe more accurate. Since the current fixtures have dead corners and are difficult to clean, it is necessary to flush the fixtures. The rotating motor can drive the rotating disk to rotate and drive the fixed column to rotate around its own axis. As the fixed column rotates, the fixed column will drive the triangle The block rotates around the axis of the fixed column. When the triangle block rotates to just below the fixed tube, the triangle block will squeeze the fixed tube and raise the fixed tube. When the triangle block moves to one side of the fixed tube, it will be fixed. The tube will fall back to the original height under the action of gravity, so the fixed tube will have volatility, so that the fixed tube will swing and increase the spray range of the fixed tube.

In summary, the present invention has the following beneficial effects:

The drive motor drives the ball to rotate and then the connecting groove to rotate. As the connecting groove rotates, the adjacent valve pipes will be continuously switched to a disconnected and connected state. In addition, the fluid flows through the other adjacent valve pipe after passing through the ball. After that, it will enter the containing block first. If the flow direction of the fluid is wrong due to the error of the operator, the closure will be closed to allow the fluid to stay in the containing block, and then the flow tube can be used to discharge the containing block to solve the problem. For the problem of fluid flow in the wrong direction, when the containing block is emptied, move the closure to make the valve tube in a circulating state again. When the communicating groove is rotated to communicate with the valve tube, the stabilizing block will move in the direction of the valve tube under the action of the spring. When the ball rotates until the communicating groove is connected to the valve tube, the stabilizing block will be stuck into the valve tube. Internally, the stabilizer block restricts the continuous rotation of the ball. When the ball continues to rotate, the ball must overcome the restriction of the stabilizer block. In this process, the stabilizer block will move toward the bottom of the groove and then squeeze the spring. After the block is not in the valve tube, the ball can continue to rotate. Processing multiple parts of the valve tube one by one helps the valve tube in the same vertical or horizontal plane to be in a coaxial position.
