[0002] During the maintenance and cleaning of the rotary valve, it was found that the cleaning effect on the inside of the valve body and the connection with the pipeline was poor.

[0003] The main reason is that when the existing rotary valve is used, when the valve body is used to transport fluids containing impurities or prone to scaling, impurities will accumulate in the valve body, and the scaling impurities will also adhere to the surface of the valve core and the inside of the valve body. In this case, the rotary valve needs to be disassembled and cleaned. In the prior art, when disassembling the rotary valve, usually only the valve core inside the valve body is removed from the inside of the valve body to clean the valve core, but it is difficult to clean the scaling inside the valve body and the scaling joint at the connection between the valve body and the external pipeline. Summary of the invention

[0004] The object of the present invention is to provide a detachable rotary valve and a maintenance method thereof, so as to solve the problem that scaling inside the valve body and the connection between the valve body and the external pipeline are difficult to clean as mentioned in the background art.

[0006] The inner ring frame is inserted into the outer ring frame, and the inner ring frame and the annular butt joint are butted against each other. Meanwhile, the aperture size inside the inner ring frame is the same as the aperture size of the butt joint through hole inside the annular butt joint.

[0007] The bottom end of the motor is fixedly connected to the top end of the receiving end by bolts, and the motor is fixedly mounted on the mounting frame by a mounting plate and bolts, and both ends of the mounting frame are fixedly mounted on the valve body.

[0008] The butt joint pipe is provided with a rubber sealing ring on the inner side of the end, and the rubber sealing ring is located between the butt joint pipe and the telescopic sleeve. When the telescopic sleeve is connected to the external water pipe, the rubber sealing ring is in a squeezed and sealed state.
