The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1:

[0032] A flexible sealing wall pipe fitting, such as Figure 1-Figure 5 As shown, it includes a working pipe 1, a valve well wall 3,

[0033] The seal 2 comprises a fixing ring 21, two rubber bushings 25 are arranged on the inner side of the fixing ring 21, a receiving chamber 22 is formed between the two rubber bushings 25, the receiving chamber 22 is used to fill with waterproof sealant, a glue injection port 26 is provided on the top of the fixing ring 21, the rubber bushing 25 is elastic, and can adapt to working pipes 1 of different sizes, thereby expanding the application scope of the seal 2, and when there is a small deviation in the size of the working pipe, the seal can still be applied, thereby improving the flexibility of pipe installation, and by filling with waterproof sealant, the leakage of liquid or gas is effectively blocked, thereby improving the waterproof performance of the valve shaft wall 3, and the glue injection port 26 is used to facilitate the injection of sealant into the receiving chamber 22, thereby simplifying the operation process.

[0034] See also Figure 1 , Figure 2 The two rubber bushings 25 are parallel to each other, and the rubber bushings 25 are fixedly connected to the fixing ring 21 by strong glue. The strong glue is used to fix the connection with the fixing ring, which enhances the adhesion between the rubber bushing and the fixing ring and ensures the firmness of the connection. A receiving cavity 22 is formed between the two parallel rubber bushings 25, and the receiving cavity 22 can limit the waterproof sealant, which is beneficial to reduce the use of the waterproof sealant.

[0035] See also Figure 2 , Figure 5 A reserved hole 31 is provided on the valve well wall 3, and the working pipe 1 passes through the reserved hole 31. The design of the reserved hole 31 enables the working pipe to be easily penetrated and installed, which simplifies the installation process and reduces the installation difficulty. The penetration and fixing method of the reserved hole and the working pipe ensures the stability and reliability of the pipeline system. Grooves 32 are provided on both sides of the valve well wall 3, and an expansion pipe 33 is inserted into the groove 32. By providing the groove and inserting the expansion pipe into the groove, the installation process is simplified and the installation efficiency is improved. When the expansion pipe needs to be maintained or replaced, it can be easily disassembled and installed, which reduces the maintenance difficulty.

[0036] Embodiment 2:

[0037] See also Figure 3 , Figure 4 , Figure 5 A locking hole 23 is provided on the outer side of the fixing ring 21, and a locking bolt 24 is provided in the locking hole 23.
