Technical Field

The invention belongs to the technical field of air compressor products, and particularly relates to a breather valve for an air compressor.

Background

The breather valve is an accessory which is arranged at the machine head and used for adjusting the pressure in the air compressor. The existing breather valve has no oil stain treatment function, and oil mist mixed in high-pressure gas is directly discharged from the breather valve, so that the environment is influenced.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: how to prevent the oil mist in the breather valve from overflowing.

In order to achieve the purpose, the technical scheme provided by the invention is as follows:

the breather valve for the air compressor comprises a shell, a shell cover, a core piece and a glass ball, wherein the shell cover covers an opening of the shell, and an exhaust hole is formed in the shell cover; an inserting part is arranged on one side, opposite to the shell cover, of the shell, an air passage communicated with an inner cavity of the shell is arranged in the inserting part, the inner core piece is arranged in the inner cavity of the shell, an inserting rod inserted into the inserting part is arranged at the position, corresponding to the air passage, of the inner core piece, and the glass ball is installed in the inserting part and movably connected with the end part of the inserting rod; the inserted bar is provided with a plurality of layers of annular convex parts, each layer of convex part is provided with a notch, and the notches of the convex parts of adjacent layers are arranged in a staggered manner.

When exhausting, the high-pressure gas pushes the glass ball to open the gas channel, the oil mist mixed in the gas is attached to the glass ball, and a first filter is formed at the glass ball; a labyrinth spiral channel is formed between the convex part of the inserted rod and the inner wall of the inserting part, gas is discharged through the channel, oil mist remained in the gas flows down along the channel after being condensed on the inserted rod or is attached to the outer wall of the inserted rod, and a second filtering channel is formed.

Compared with the prior art, the invention has the beneficial effects that: according to the invention, two filters are arranged in the breather valve, so that oil mist is effectively prevented from overflowing, and the breather valve is more environment-friendly.
