The front end of the embedded pin 705 is narrow so as to be inserted into the connecting seat II 701, and then the embedded pin 705 is hammered to be forcibly inserted into the connecting seat II 701, so that the embedded pin 705 can be pulled out without a stress point, and the valve body 1 is partially prevented from being stolen. The annular groove facilitates a firm fixation with poured concrete. When the cover is opened, the maintenance liquid is dropped onto the coating roller 303 through the inlet pipe II 301, and the valve plate 2 can be maintained when being lifted. The opening of the exchange tube 401 is provided with a cover which can be opened or closed, the exchange tube 401 at a high position injects cleaning liquid into the lower valve body 4, the valve plate 2 descends, then the valve plate 2 is enabled to be coincident with the axis of the output shaft of the motor 5, the electric push rod 504 is started to enable the connecting rod 501 to enter the inner annular surface, the motor 5 is started to drive the connecting rod 501 to rotate to independently clean the inner annular surface of the valve plate 2, scale or rust on the connecting rod is removed, and the cleaning liquid after use is discharged through the exchange tube 401 at a low position. The wiping sheet 502 increases the cleaning effect. The valve plate 2 descends to surround the inlet pipe I104 by the inner annular surface of the valve plate 2, and liquid for removing dirt is filled into the inlet pipe I104 and flows onto the inner end surface of the lower part of the valve plate 2. The heating ring 402 and the heating rod 403 are used for freeze protection. The one-way movement direction of the stepped valve plate 602 can be changed by changing the installation direction of the connecting pipe 6, and then the backflow prevention function is achieved according to the requirement.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and that various changes, modifications, additions and substitutions which are within the spirit and scope of the present invention and which may be made by those skilled in the art are also within the scope of the present invention.
