Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a high-pressure filter. Background Art

[0002] High-pressure filter is an indispensable device on the medium conveying pipeline. It is usually installed at the inlet end of pressure reducing valve, pressure relief valve, constant water level valve, Fanggong filter and other equipment. High-pressure filter is needed to absorb and remove moisture and ash in high-pressure air to obtain relatively pure air.

[0003] For example, a high-pressure filter provided in Chinese patent application No. 202320002344.0 includes an input shell, a display mechanism, a water suction cylinder, and a filter shell. The upper outer portion of the input shell is fixedly connected to the display mechanism, which includes a fixed tube, a transparent tube, and a piston. The top of the fixed tube is fixedly connected to the transparent tube, and the fixed tube is movably connected to the piston. One side of the input shell is fixedly connected to the water suction cylinder, and spiral blades are fixed on the inner wall of the water suction cylinder. The side of the water suction cylinder away from the input shell is fixedly connected to the filter shell. This technical solution solves the problem that the high-pressure filter filters moisture and ash separately, and the high-pressure air passes through two-step filter element filtration, which causes a large pressure loss and is inconvenient to detect whether the filtration efficiency is qualified. The advantages of this technical solution are: the pressure loss of high-pressure air that filters moisture and ash is small, and it is more convenient to detect whether the filtration efficiency is qualified.
