At the same time, water sources must be reasonably arranged to avoid wasting water resources.

[0003] According to a pipe connection flange disclosed in patent search announcement number CN208503715U, its beneficial effects are: the four clamping blocks are pushed to gather toward the middle at the same time by a locking sleeve, thereby clamping the pipe, thereby strengthening the coaxiality of the flange and the pipe, and at the same time, injection liquid can be added to the injection molding groove through the injection molding hole to seal and fix the pipe. By moving the clamping block, the flange can be connected to pipes of different sizes, thereby increasing the versatility of the flange, and the structure is simple and cost-saving.

[0004] During the use of pipeline connecting flanges, they will need to be frequently maintained, and may even need to be disassembled. However, connecting flanges are generally integral and difficult to disassemble effectively, which affects the daily maintenance of the connecting flanges. Utility Model Content

When the secondary connecting flange 6 is installed and plugged into the secondary connecting sleeve 5, the slidable support block 703 is driven to slide inward on the auxiliary limiting support rod 702, and the slidable support block 703 slides inward with friction on the rubber limiting clamp rod 705, and the reinforcement plug rod 704 is plugged into the secondary connecting flange 6, so that the connecting flange can be disassembled and installed in time when an error occurs, thereby avoiding affecting the daily maintenance of the connecting flange.

[0026] See also Figures 1-2 The bottom of the secondary connecting flange 6 is fixedly connected with a rubber sealing ring 8. The upper end of the primary connecting sleeve 2 is plugged into the lower end of the secondary connecting sleeve 5. The rubber sealing ring 8 provides a waterproof seal for the connection between the secondary connecting sleeve 5 and the secondary connecting flange 6 to prevent water from seeping out from the connection between the secondary connecting sleeve 5 and the secondary connecting flange 6 and affecting the discharge of water.

[0027] See also Figures 1-2 Both sides of the upper end of the main supporting chassis 1 are fixedly connected with top frames 9, and the inner wall of the top frame 9 is rotatably connected with installation limit bolts 10.

[0028] See also Figures 1-2 The middle parts of the front and back sides of the secondary connecting sleeve 5 are fixedly connected with supporting buckles 11, and the top of the front side of the secondary connecting flange 6 is fixedly connected with a raised top block 12. One end of the limiting reinforcement unit 7 is plugged into one side of the secondary connecting flange 6. When the fingers are buckled on the supporting buckle 11, the secondary connecting sleeve 5 and the slidable top rod 4 can slide upward or downward on the limited supporting shaft rod 3, so that the secondary connecting sleeve 5 and the primary connecting sleeve 2 are in a loose and installed state, which is convenient for removing impurities inside the primary connecting sleeve 2 to avoid clogging of the connecting flange.

The surface of the auxiliary limiting support rod 702 is slidably connected to a slidable support block 703. The auxiliary limiting support rod 702 and the rubber limiting clamping rod 705 limit the sliding of the slidable support block 703 in the horizontal direction to avoid the situation where the sliding direction of the reinforcement plug rod 704 is deviated and it is difficult to correctly plug it into the socket opened on the secondary connecting sleeve 5.

[0030] See also Figure 3 The upper end of the sliding support block 703 is fixedly connected with a reinforcing rod 704, and one end of the sliding support block 703 is fixedly connected to the upper end of the main auxiliary top block 701 through a rubber limit rod 705. The parameters of the rubber limit rod 705 are set as: a copolymer of butadiene and acrylonitrile, generally containing 18%, 26% or 40% acrylonitrile. The higher the content, the better the oil resistance, heat resistance and wear resistance. The operating temperature range is -55 to 130°C.
