[0024] Working principle: The pipe interface device 2 blocks the water flow through the water-blocking baffle 202 and the water-blocking plug 202. The spring as an auxiliary can better prevent the leakage of water. The power rack 205 is meshed with the power device 3. The water-blocking baffle 202 and the water-blocking plug 202 are controlled by the rotating shaft 305 to block the water flow. The power device 3 is turned clockwise to close, and the power device 3 is turned counterclockwise to open. The water-blocking baffle 201 and the water-blocking plug 202 are opened under the action of the power rack 205, so that the water-blocking baffle 201 and the water-blocking plug 202 form a Y-shaped gap to determine the size of the water. When it is needed To connect the transmission pipe, it is connected through the card slot. When the connector needs to be opened, the power device is turned, and the power device meshes with the gear bar to make the water-blocking plug move forward and push it to the other water-blocking plug. The two forces make the water-blocking plug into an hourglass shape to allow gas or liquid to flow from both ends. If the connection needs to be cancelled, pull out the pipe joint. Under the dual action of the spring and pressure, the spring rebound pressure leaks out and makes the water-blocking plug push against the water-blocking baffle. When the main switch device needs to be closed, the switch gear column fixed on the bolt column engages with the switch rack. The upper and lower baffles and the upper and lower baffles on the bolt column make a 180-degree opening and closing operation.
