The limiting piece 64 is located inside the activity groove 5, and the right end of the spring 65 is fixedly connected to the right groove wall of the activity groove 5.
[0033] Through the above solution: By placing the connecting cylinder 71 on the right side of the connecting seat 9, inserting the connecting cylinder 71 into the connecting groove 10, simultaneously engaging the two positioning bars 73 into the two positioning grooves 11 respectively, and making the sealing ring 72 closely fit with the left groove wall of the connecting groove 10, then by rotating the two locking screws 12, the ends of the two locking screws 12 are both in contact with the connecting cylinder 71, so that the connecting cylinder 71 can be limited, thus facilitating the quick and convenient installation of the pressure-taking cylinder 1, and it can be easily disassembled for regular inspection, cleaning or maintenance, timely discovering and solving possible faults or damages, ensuring the normal operation of the pressure relief function, thereby improving the overall reliability and safety of the heating wall-mounted boiler, and the convenient disassembly enables more thorough cleaning of its interior, removing possible accumulated dirt, impurities, etc., preventing its blockage or affecting the pressure relief effect, and prolonging the service life of the device.

At the same time, the two positioning strips 73 are used to achieve a firm snap connection with the corresponding positioning grooves 11 to ensure the accuracy of the connection. In addition, the sealing ring 72 closely adheres to the left groove wall of the connecting groove 10 to effectively prevent gas leakage. To further enhance the stability of the connection, the two locking screws 12 are rotated until the ends of the two locking screws 12 closely adhere to the connecting cylinder 71 to form a reliable limiting effect. This not only simplifies the installation process of the pressure-taking cylinder 1, making it fast and convenient, but also facilitates subsequent regular disassembly inspection, in-depth cleaning, and necessary maintenance work. In this way, potential faults or damages can be timely detected and solved, ensuring that the pressure relief function of the heating wall-mounted boiler is always in the best state, thereby enhancing the reliability and safety of its overall operation. Furthermore, a pressure-taking groove 3 is provided on the left side inside the pressure-taking cylinder 1, and the pressure-taking groove 3 is connected to the exhaust pipe 8. When the internal pressure of the heating wall-mounted boiler exceeds the set value, the force of the pressure will push the regulating block 61 to move to the right, thereby opening the exhaust pipe 8 to smoothly discharge the excess pressure; conversely, when the pressure drops, the regulating block 61 automatically resets and moves to the left under the elastic force of the spring 65 to re-close the exhaust pipe 8. This process does not require manual intervention, greatly reducing the frequency of manually adjusting the pressure valve and improving the convenience and efficiency of use.
