Description
Technical field
The present invention relates to a kind of air compressor machine technology, especially a kind of vortex oilless air compressor, specifically a kind of list
To the oil-free scroll formula air compressor machine built in valve.
Background technique
It is well known that the high pressure gas of vortex oilless air compressor is needed after the extraction of quiet disk by multiple check valves 10
Outside energy extractor, i.e., oil-free scroll non-return valve for air compressor is in external pipeline, as shown in Figure 1, will increase pipe-line system piece-ups
Measure at least four.Production efficiency craftsmanship is poor, production assembly cost is high, the more at least four points of pipe-line system leakage point, current to this
The solution that there is no.
Summary of the invention
The purpose of the present invention is for existing oilless air compressor external one-way valve, that there are connectors is more, leak fall into suffer from it is corresponding
The problem of increase, designs the oil-free scroll formula air compressor machine built in a kind of check valve.
The technical scheme is that
A kind of oil-free scroll formula air compressor machine built in check valve, it includes quiet disk 1 and exhaust pipe 2, and the inlet end of exhaust pipe 2 is fixed
On the exhaust end of quiet disk 1, it is characterized in that built-in check valve is installed between quiet disk air exit end and exhaust pipe air inlet,
The built-in check valve is made of exhaust valve plate 3, lift stopper 4, exhaust valve plate 5, one end of exhaust valve plate 3 and quiet disk exhaust outlet
Step surface offsets, and one end of the other end and lift stopper 4, which offsets or is inserted into, to be located in lift stopper 4, lift stopper 4
The inlet end of the other end and exhaust pipe 2 offset, exhaust valve plate 5 is mounted in lift stopper 4 and can move axially, exhaust
Valve plate 3 is equipped with ring-shaped ventilation ring 6, and center is equipped with plugging block 7, and the outer ring of exhaust valve plate 5 can cover the ring on exhaust valve plate 3
The plugging block 7 of shape ventilation ring 6, exhaust 3 center of valve plate can cover the central through hole of exhaust valve plate 5；In lift stopper 4 close to row
At least two axially extending bores 8, the outer ring of check valve sheet 3 are provided on the side of tracheae 2 can also cover the axially extending bore.
The quantity of the axially extending bore is 3, they are evenly arranged on 4 end face of lift stopper.
Sealing ring 9 is added between 4 outside of lift stopper and quiet disk exhaust passage, sealing ring 9 is sleeved on liter
On journey limiter 4.
Beneficial effects of the present invention:
The configuration of the present invention is simple, part are few, it is only necessary to which 4 small parts are the function of realizing check valve, the list of opposing lines system
To valve finished product, number of parts reduces 50%, and production cost is only the 10% of market conventional products total price, and volume is only that market is routinely used
Check valve finished-product volume 5%.And this Standard craftsmanship is simple, it is easy for installation.
Detailed description of the invention
Fig. 1 is existing air compressor machine gas exhaust piping structural schematic diagram.
Fig. 2 is structural schematic diagram of the invention.
Fig. 3 is the structural schematic diagram of exhaust valve plate of the invention.
Fig. 4 is the structural schematic diagram of lift stopper of the invention.
Fig. 5 is the structural schematic diagram of check valve sheet of the invention.
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 2-5.
A kind of oil-free scroll formula air compressor machine built in check valve, it includes quiet disk 1 and exhaust pipe 2, the inlet end of exhaust pipe 2
It is fixed on the exhaust end of quiet disk 1, built-in check valve is installed between quiet disk air exit end and exhaust pipe air inlet, such as scheme
Shown in 2, the built-in check valve is by exhaust valve plate 3(Fig. 3), lift stopper 4(Fig. 4), exhaust valve plate 5(Fig. 5) and 9 groups of sealing ring
At, sealing ring 9 is sleeved on lift stopper 4, exhaust valve plate 3 one end offset with quiet disk exhaust outlet step surface, the other end and
One end of lift stopper 4, which offsets or is inserted into, to be located in lift stopper 4, the other end and the exhaust pipe 2 of lift stopper 4
Inlet end offsets, and exhaust valve plate 5 is mounted in lift stopper 4 and can move axially, and exhaust valve plate 3 is equipped with ring-shaped ventilation
Ring 6, center are equipped with plugging block 7, and plugging block 7 is connected by dowel with the outer ring for being vented valve plate 3, as shown in Figure 3.Exhaust valve
The outer ring of piece 5 can cover the ring-shaped ventilation ring 6 on exhaust valve plate 3, and the plugging block 7 at exhaust 3 center of valve plate can cover exhaust valve plate 5
Central through hole；It is opened on the side of exhaust pipe 2 there are three axially extending bore 8 and is evenly arranged (Fig. 4) in lift stopper 4,
The outer ring of check valve sheet 3 can also cover the axially extending bore,
The working principle of the invention is:
When quiet disk normal exhaust, high pressure gas is discharged from quiet disk exhaust outlet, and exhaust valve plate is forced into lift by the air pressure and limits
On the end face in 4 left side of device and axially extending bore 8 is covered, high pressure gas passes through exhaust valve plate center from the circular passage of exhaust valve plate
Through-hole is discharged into exhaust pipe 2 from the hole among lift stopper again
When oil-free scroll air compressor machine stop motion, quiet disk high pressure chest no pressure, gas is from 2 back pressure of exhaust pipe, lift stopper 4
Exhaust valve plate 3 is pressed onto exhaust valve and pulled on 3 by three axially extending bores on outer ring edge, and exhaust valve is pulled 3 by the outer ring of exhaust valve plate 5
Ring-shaped ventilation ring 6 cover, and the plugging block 7 for being vented 3 center of valve plate just blocks the centre bore of exhaust valve plate 5, exhaust pipe
In gas method enter quiet disk in.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
