Problems solved by technology

The differential pressure automatic drain adopts the principle of differential pressure (pulse type) drainage. When the disc piston moves down to the state of air pressure balance under the pressure of compressed air, the flange that folds down around the disc piston It is in close contact with the inner wall of the water cup to form a sealing ring. The filtered water at the upper part of the disc piston cannot enter the airtight chamber at the lower part.

Abstract

The invention discloses a pulse-type drainage air filter, comprising a filter body and a cup disposed on the filter body; a filter assembly fixedly connected with the filter body is arranged in the cup; the lower end of the cup is provided with a drainage passage; a pulse-type drainage mechanism is disposed in the cup; the pulse-type drainage mechanism comprises a piston seat fixedly installed in the cup and a piston slidingly arranged in the piston seat; a filtered water passage is disposed between the piston seat and the piston seat; one end of the piston protrudes out of the piston seat and abuts against the drainage passage; an air gap communicated with the inner cavity of the cup is disposed between the piston and the piston seat; and the piston and the piston seat cooperate to form a balance pressure chamber in the piston seat. The pulse-type drainage air filter described by the invention can realize pulse-type automatic drainage, is simple in structure, low in production cost and is convenient for disassembly and maintenance, and has relatively long service life.

Description

technical field [0001] The invention relates to the technical field of pneumatic components, in particular to a compressed air filter with a pulsed drainage structure. Background technique [0002] In the field of pneumatic components, the compressed air filter is an air source treatment element that filters and discharges the moisture in the compressed air. The humidity of the compressed air after treatment is reduced, which can prevent the inner wall of the pipeline and the valve core of the air control component from rusting. The compressed air filter mainly includes a filter body, a filter element, a water cup and a drainage mechanism. The filter body is provided with a compressed air inlet and an outlet. The compressed air enters the interior of the filter body from the inlet, and after being filtered by the filter element, the dry air is discharged from the outlet. , the water filtered by the filter element is collected in the water cup, and the water in the water cup ...
