The water inlet joint 14 is arranged on the cabin 11 and communicated with the water storage cavity 102 for connecting an external water path. Therefore, when the water temperature in the water storage cavity 102 is too low or too high, the diaphragm 12 is deformed due to the change of the water volume or pressure in the water storage cavity 102, and then the air cavity 101 adjusts the air pressure in the air cavity 101 through the air valve 13, so that the influence of the water volume or pressure change on the pressure-regulating cabin body 1 is eliminated, and the service life of the pressure-regulating cabin body 1 is ensured.
Further, the cabin 11 includes an upper cabin shell 111 and a lower cabin shell 112 that are connected to each other in a matching manner, so as to facilitate the assembly and disassembly of the membrane 12. The upper shell 111 of the chamber and the membrane 12 enclose an air chamber 101, and the lower shell 112 of the chamber and the membrane 12 enclose a water storage chamber 102.
