The utility model belongs to the technical field of water supply equipment, particularly relates to a time period flow adjusting device for variable-frequency water supply equipment, and aims to solve the problems that the flow adjusting mode of the conventional water supply equipment is single, accurate and real-time regulation and control are inconvenient, the device is complicated and easy to break down, the display of the adjusting state is not visual enough and the like. A water supply channel is formed in the connecting part, water inlet and outlet pipelines are fixedly installed on the two sides of the connecting part, and the two water inlet and outlet pipelines are communicated with the water supply channel and used for facilitating connection between the connecting part and an external water supply pipeline. According to the time period flow adjusting device of the variable-frequency water supply equipment, the rotating angle of the adjusting shaft can be accurately controlled through the servo motor, the water flow can be flexibly and accurately adjusted, and the differentiated water use requirements of different time periods are met; a water through hole is formed in the adjusting valve element, basic water flow supply is guaranteed, and water supply interruption is avoided; the device is compact in structure, reasonable in design, close in component matching and good in equipment stability and reliability.

This invention relates to the field of grinding robot technology, and more particularly to a gasbag-inflatable variable-diameter pipe grinding robot. It includes an inflatable grinding component, a dual-rotation component, a moving component, and a steering connection mechanism. The inflatable grinding component covers the dual-rotation component. The moving component is mounted and fixed on both sides of the dual-rotation component and has three branches, each connected to a support wheel. The steering connection mechanism is fixedly installed on both sides of the moving component via steering connecting rods and bolts. This invention uses a gasbag inflator, which improves the efficiency of grinding the inner wall of the pipe and ensures sufficient and uniform coverage of the grinding surface. By controlling the inflation pressure of the gasbag, the grinding force can be controlled and adjusted. Simultaneously, the variable-diameter function can be achieved through the connecting rod, adapting to different pipe diameter conditions, and enabling continuous movement within multiple sections of the pipe.
