The valve body is provided with a fixed chamber at the position of the water inlet channel. A rotating rod is rotatably passed through the fixed chamber. A water blocking plate is provided at the bottom, and the water blocking plate drives the rotating rod to rotate. A damping device for hindering the rotation of the water blocking plate is provided between the valve body and the rotating rod. A telescopic device for making the water blocking plate extend into the water inlet channel is also provided on the rotating rod.
[0006] Further improvement is: The damping device includes a T-shaped sliding block. A fixed block is provided between the valve body and the fixed chamber. The fixed block is provided with a T-shaped groove. The sliding block is slidably arranged in the T-shaped groove. A pull rope is wound around the rotating rod, and the other end of the pull rope is connected to the sliding block. A damping member is provided between the sliding block and the valve body.
[0007] Further improvement is: The damping member is a damping spring. One end of the damping spring is connected to the sliding block, and the other end of the damping spring is connected to the outer wall of the valve body.
[0008] Further improvement is: The telescopic device includes a telescopic rod. The telescopic rod is passed through the rotating rod. The water blocking plate is provided at the end of the telescopic rod. A sliding device for driving the telescopic rod to slide is provided on the rotating rod.

[0016] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] Refer to Figure 1-2 , what is disclosed in the embodiment of the present utility model is: A valve with an anti-blocking function, including a valve body 1, a valve cover 5 provided on the valve body 1, an inlet channel 2 and an outlet channel 3 opened on the valve body 1, a valve plate 4 provided between the inlet channel 2 and the outlet channel 3, a T-shaped sliding block 14, a valve rod 6 provided on the valve body 1, one end of the valve rod 6 is connected to the valve plate 4, the other end of the valve rod 6 passes through the valve cover 5, the valve body 1 is provided with a fixed chamber 8 at the position of the inlet channel 2, a rotating rod 10 is rotatably penetrated in the fixed chamber 8, a water baffle 9 is provided at the bottom of the rotating rod 10, the water baffle 9 drives the rotating rod 10 to rotate, a fixed block 11 is provided between the valve body 1 and the fixed chamber 8, the fixed block 11 is provided with a T-shaped groove 12, the sliding block 14 is slidably arranged in the T-shaped groove 12, a pull rope 13 is wound around the rotating rod 10, the other end of the pull rope 13 is connected to the sliding block 14, a damping spring 15 is provided between the sliding block 14 and the valve body 1, one end of the damping spring 15 is connected to the sliding block 14, the other end of the damping spring 15 is connected to the outer wall of the valve body 1, and a telescopic device for making the water baffle 9 extend into the inlet channel 2 is further provided on the rotating rod 10.
[0018] Specifically, the telescopic device includes a telescopic rod 18 and a screw rod 17. The telescopic rod 18 is disposed through the rotating rod 10. The water baffle 9 is arranged at the end of the telescopic rod 18. The screw rod 17 is rotatably disposed through the rotating rod 10. One end of the screw rod 17 is disposed through the telescopic rod 18 and is in threaded transmission with the telescopic rod 18. The other end of the screw rod 17 passes out of the rotating rod 10. The telescopic rod 18 is arranged in a square shape.
[0019] Among them, when in use, when the valve needs to be closed, first manually restrict the rotation of the rotating rod 10, and then rotate the screw rod 17. The screw rod 17 is in threaded transmission with the telescopic rod 18, driving the telescopic rod 18 to slide out of the rotating rod 10, so that the water baffle 9 descends and slides into the water inlet channel 2, and then the valve is closed. When the water hammer enters from the water inlet channel 2, it first strikes on the water baffle 9. The water baffle 9 flips, driving the rotating rod 10 to rotate. After the rotating rod 10 rotates, it pulls the pull rope 13. The pull rope 13 pulls the sliding block 14, and the sliding block 14 pulls the damping spring 15, thereby playing a buffering role to eliminate the force generated by the water hammer, reducing the generation of the water hammer, so that the water hammer will not directly strike the valve plate 4 and cause the valve plate 4 to be easily damaged, thereby improving the service life of the valve.
[0020] In order to prevent impurities from entering the inside of the valve body 1 and blocking the inside of the valve body 1, a filter screen 7 is provided at the mouth of the water inlet channel 2.
[0021] In order to further play a role in eliminating the water hammer, a friction layer is provided at the bottom of the T-shaped groove 12, and the bottom of the sliding block 14 abuts against the friction layer.
[0022] In order to facilitate the rotation of the screw rod 17, a hand wheel 16 is provided on the screw rod 17.
