The number of the axial through holes is 3, and the axial through holes are uniformly distributed on the end surface of the lift limiter 4.

A sealing ring 9 is additionally arranged between the outer side of the lift limiter 4 and the exhaust channel of the static disc, and the sealing ring 9 is sleeved on the lift limiter 4.

The utility model has the advantages that:

the utility model discloses simple structure, the part is few, only needs 4 little parts to realize the function of check valve promptly, and relative pipe-line system's check valve finished product, part quantity reduce 50%, and manufacturing cost only is the 10% of market conventional product total price, and the volume only is market conventional with check valve finished product volume 5%. And the structure has simple assembly manufacturability and convenient installation.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 2-5.

An oil-free vortex air compressor with a built-in one-way valve comprises a static disc 1 and an exhaust pipe 2, wherein the air inlet end of the exhaust pipe 2 is fixed on the air outlet end of the static disc 1, a built-in one-way valve is arranged between the air outlet end of the static disc and the air inlet end of the exhaust pipe, as shown in figure 2, the built-in one-way valve consists of an exhaust valve plate 3 (figure 3), a lift limiter 4 (figure 4), an exhaust valve plate 5 (figure 5) and a sealing ring 9, the sealing ring 9 is sleeved on the lift limiter 4, one end of the exhaust valve plate 3 is abutted against the step surface of the air outlet end of the static disc, the other end of the exhaust valve plate 3 is abutted against or inserted and positioned in the lift limiter 4, the other end of the lift limiter 4 is abutted against the air inlet end of the exhaust pipe 2, the exhaust valve plate 5 is arranged in the lift limiter 4 and can move axially, the exhaust valve plate, the block 7 is connected to the outer ring of the exhaust valve plate 3 by a connecting rib, as shown in fig. 3. The outer ring of the exhaust valve plate 5 can cover the annular ventilation ring 6 on the exhaust valve plate 3, and the blocking block 7 at the center of the exhaust valve plate 3 can cover the central through hole of the exhaust valve plate 5; three axial through-holes 8 are provided in the lift stop 4 on the side facing the exhaust pipe 2 and are arranged uniformly (fig. 4), and the outer ring of the exhaust valve plate 3 also covers the axial through-holes.

The utility model discloses a theory of operation is:

when the static disc normally exhausts, high-pressure gas is exhausted from an exhaust port of the static disc, an exhaust valve plate is pressed on the end face on the left side of the lift limiter 4 through the air pressure and covers the axial through hole 8, the high-pressure gas penetrates through a through hole in the center of the exhaust valve plate from an annular channel of the exhaust valve plate and then is exhausted from a hole in the middle of the lift limiter to enter the exhaust pipe 2, when the oilless vortex air compressor stops moving, the static disc high-pressure cavity has no pressure, the gas is back-pressed from the exhaust pipe 2, the exhaust valve plate 5 is pressed on the exhaust valve plate 3 through three axial through holes in the edge of the outer ring of the lift limiter 4, the annular vent ring 6 of the exhaust valve plate 3 is covered by the outer ring of the exhaust valve plate 5, the sealing block 7 in the center of the exhaust valve plate 3 just plugs the center.

The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
