Multifunctional filter unit

Abstract

The invention relates to a filter unit, specifically to a filter unit for separating magnetic impurities, particle impurities and gases from a fluid. The filter unit is especially applicable to heating pipelines or air-conditioning systems. A multifunctional filter unit comprises a main body, a water inlet cover, and a locking cap which is clamped on the water inlet cover and tightens up the mainbody. A blind hole cavity used for planting a magnetic strip is arranged at the lower end of the main body. A blowoff valve is arranged at the lateral side of the bottom of the cavity of the main body. A fixed through hole is arranged at the opposite side of the blowoff valve. The upper end of the water inlet cover is equipped with a first fixed hole, a second fixed hole and a third fixed hole. The first fixed hole and the third fixed hole are horizontally and coaxially arranged. In the cavity of the main body, one end of a bend channel is connected with the first fixed hole, and the other endof the bend channel is connected with a cylindrical filter screen. The filter unit of the invention can meet access requirement of pipelines from multi-directions and multi-angles. The filter unit ofthe invention has a simple structure, is flexible to adjust, has high adaptability, and has market competitiveness.

Description

technical field [0001] The invention relates to a filter device, in particular to a filter device for separating magnetic impurities, particulate impurities and gas in a fluid, and is especially suitable for use in heating pipes or air conditioning systems. Background technique [0002] In the fields of heating systems and air-conditioning systems such as radiator heating and floor heating heating, pipeline hot water, ethylene glycol solution and other heat media, due to the presence of impurities such as valves, radiators, pipelines and other components and media such as iron and calcium ions, pollution The circulation system will accelerate the internal corrosion and damage of the pipeline, especially the fragile equipment such as condensation furnace and temperature and pressure measurement. The iron-containing impurities cannot be removed through the commonly used filter screen, and it is inconvenient to use a protective liquid, etc., which need to be added regularly. T...
