When the water pipe and the connecting valve are connected, one end of the water pipe is inserted into the interior of the connecting sleeve. At this time, one end of the water pipe will contact one side of the support ring. As the water pipe continues to be inserted, the support ring will slide to one side under the action of the water pipe, and the support ring will squeeze the airbag when sliding. At this time, the gas inside the airbag will be transported to the inside of the sealing ring through the conduit after being squeezed, and the air pressure inside the sealing ring will increase due to the input of the gas.

[0016] 2. The present invention provides an anti-slip mechanism. When irrigating farmland, water will enter the valve body through the water inlet pipe and be discharged through the drain pipe. During this period, the water will contact the anti-slip mechanism, and the impeller will drive the rotating rod to rotate under the action of the water flow. At this time, the blades will rotate with the rotation of the rotating rod, so that the water flow can be dispersed by the rotation of the blades, so as to reduce the impact force of the water flow and prevent the connection valve and the water pipe from falling off due to the strong impact force of the water flow, thereby affecting the transportation of the water flow. When the rotating rod rotates, it will drive the connecting ring to rotate synchronously At this time, when the top block contacts the push block during rotation, as the connecting ring continues to rotate, the top block will push the push block to slide to one side, and the push rod will drive the piston plate to slide inside the sleeve under the action of the push block. At this time, the air pressure inside the cavity will increase with the sliding of the piston plate, and the gas inside the cavity will be ejected through the injection pipe under the action of the air pressure, so as to offset the impact force of the water flow through the injection force of the air flow, thereby improving the connection effect between the connecting valve and the water pipe, and preventing the connecting valve and the water pipe from falling off due to the impact of the water flow, thereby affecting the irrigation of farmland.
