Preferably, the flange plate is provided with a round hole, and the valve body and the inner wall of the round hole are welded and fixed together.

Preferably, a first bearing is arranged in the rotating hole, an outer ring of the first bearing is welded and fixed with the inner wall of the rotating hole, and an inner ring of the first bearing is fixedly sleeved on the driving rod.

Preferably, the buffer tube is provided with a plurality of holes which are annularly arranged.

Preferably, a second bearing is arranged in the rotating hole, an outer ring of the second bearing is welded and fixed with the inner wall of the rotating hole, and an inner ring of the second bearing is fixedly sleeved on the driving rod.

Preferably, the valve plate is provided with a fixing hole, and the driving rod and the inner wall of the fixing hole are welded and fixed together.

Compared with the prior art, the beneficial effects of the utility model are that: when the valve can be closed to the actuating lever opening at the rotation, the actuating lever can drive the valve plate and rotate when rotating, along with the valve plate when rotating, the rivers of high-speed flow in the valve body of flowing through at first can strike one of them buffer tube, because the shape of buffer tube is a trapezoidal drum, thereby alright with buffering liquid, so that slow down the impact of liquid to the valve plate, therefore make the valve plate can obtain a better protection, and the liquid that flows through the valve plate will carry out the secondary buffering to liquid under the effect of another buffer tube, thereby carry out a better protection to the water pipe of connecting.

The utility model is simple in operation, convenient to use can reduce the impact that the liquid of flowing through the valve caused the valve to make the valve obtain betterly.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a wear-resistant structure of a butterfly valve comprises a valve body 1, wherein flange plates 2 are fixedly welded on two sides of the valve body 1, a rotating groove 3 and a rotating hole 4 are respectively formed in the inner walls of the bottom and the top of the valve body 1, a same driving rod 5 is rotatably mounted in the rotating groove 3 and the rotating hole 4, the top end of the driving rod 5 extends out of the rotating hole 4, a valve plate 6 is fixedly welded in the valve body 1, the valve plate 6 and the driving rod 5 are fixedly welded together, and two buffer tubes 7 are fixedly welded in the valve body 1;

the flange plate 2 is provided with a round hole, the valve body 1 and the inner wall of the round hole are welded and fixed together, a first bearing is arranged in the rotating hole 4, the outer ring of the first bearing is welded and fixed with the inner wall of the rotating hole 4, the inner ring of the first bearing is fixedly sleeved on the driving rod 5, the buffer tube 7 is provided with a plurality of holes which are annularly arranged and communicated, a second bearing is arranged in the rotating hole 4, the outer ring of the second bearing is welded and fixed with the inner wall of the rotating hole 4, the inner ring of the second bearing is fixedly sleeved on the driving rod 5, the valve plate 6 is provided with a fixed hole, the driving rod 5 and the inner wall of the fixed hole are welded and fixed together, when the rotating driving rod 5 is opened, the valve is closed, the driving rod 5 can drive the valve plate 6 to rotate, and along with the rotation of the valve plate 6, because the shape of buffer tube 7 is a trapezoidal drum to alright can cushion liquid, so that slow down the impact of liquid to valve plate 6, therefore make valve plate 6 can obtain a better protection, and the liquid that flows through valve plate 6 will carry out the secondary to liquid under another buffer tube 7's effect and cushion, thereby carry out a better protection to the water pipe of connecting, the utility model is simple in operation, convenient to use can reduce the impact that the liquid of flowing through the valve caused the valve, thereby makes the valve obtain better.
