Abstract

The invention discloses a natural gas inlet filter device. The natural gas inlet filter device comprises a filter cylinder and a filter element vertically arranged in the filter cylinder, wherein the filter cylinder is provided with an inlet channel communicating with the outside of the filter element and an outlet channel communicating with the inside of the filter element; the middle of the filter element is provided with a fixing screw rod vertically arranged; the filter element is fixedly connected with the top of the outlet channel through the fixing screw rod; the top of the filter element is provided with a positioning seat compacting the filter element downwards; an annular sheet capable of vertically moving along the filter cylinder under the action of the air pressure and a cushion chamber communicating with the filter cylinder are arranged in the filter cylinder; a piston and a piston spring for resetting the piston to the opening of the cushion chamber are arranged in the cushion chamber; and a spacing pin for releasing the spacing of the piston and the cushion chamber when the annular sheet moves upwards is arranged in the filter cylinder. The invention aims to provide a natural gas inlet filter device which effectively prevents a filter element from being damaged.

Description

technical field [0001] The invention belongs to the field of natural gas systems, in particular to a natural gas inlet filtering device. Background technique [0002] At present, the filter in the natural gas system is usually composed of a filter cartridge and a filter element.
