[0011] By adopting the above technical solution, the bottom of the filter cartridge is plugged into the valve seat ring, so that the filter cartridge is firmly locked in the radial direction to reduce shaking.

[0012] As a further optimization of the utility model, the end faces of the shell and the valve cover opposite to each other are respectively provided with a third annular groove and a fourth annular groove, and a sealing octagonal ring is provided between the third annular groove and the fourth annular groove.

[0013] By adopting the above technical solution and setting a sealing octagonal ring structure, a better sealing effect can be achieved under high pressure conditions.

[0014] As a further optimization of the utility model, the shell is provided with a plurality of lifting eye screws on the same side of the water inlet, and the bottom of the shell is provided with a plurality of prepared lifting holes.

[0015] By adopting the above technical solution, setting lifting eye screws and preparing lifting holes, it is possible to ensure that the finished product can be lifted in multiple postures, which is convenient for testing, transportation and installation.

[0016] The beneficial effects of the utility model are as follows: the housing is forged in one piece, and material defects are not likely to occur, because the need for There is no welding situation, and there is no welding part on the pressure side, so as to avoid leakage caused by welding defects due to welding quality or long-term use. During assembly, the first bracket ring is placed in the first annular groove, and the second bracket ring is placed in the second annular groove. Then the filter cartridge is placed in the inner cavity, and the side wall of the filter cartridge is fixed to the first bracket ring and the second bracket ring, and then the valve cover is connected to the valve body. The valve cover presses the top of the filter cartridge, thereby pressing the first bracket ring to the bottom of the first annular groove, and pressing the second bracket ring to the bottom of the second annular groove, and the filter cartridge is firmly locked in the axial direction, thereby realizing the non-welding fixation between the filter cartridge and the shell, so it can be suitable for high-pressure working conditions.
