Description
Technical field
The utility model relates to a kind of air compressor, relates in particular to a kind of piston valve type oilless air compressor of importing air-flow via crankcase.
Background technique
Air compressor is one of industrial field common equipment, and its suction port and air outlet are located at the both sides on cylinder top respectively, and application shows that there is following defective in this structure: air flue is narrow, and source of the gas is inadequate, makes piston load overweight, the waste energy consumption; Valve plate and suction port are too near, and bouncing of valve block and valve plate produces bigger noise; Intake duct, air outlet flue relative narrower, the air flow friction is bigger, and atmosphere temperature rising is high in the short time, influences air quality, and reduces the rigidity intensity of accessory.
In addition, the crankcase of existing air compressor perhaps uses the machine oil cooling and lubricating, causes resource consumption; Or do not have oily crankcase under closed state, and air does not flow, and the heat that causes bearing, connecting rod, bent axle friction to produce can't discharge, and heating will influence the rigidity reduction in strength of accessories such as connecting rod, piston, bent axle, bearing, shorten the working life of accessory.
Summary of the invention
The purpose of the utility model is to provide a kind of piston valve type oilless air compressor, to solve the problem that air flue is narrow and small, resource consumption is high and working life is short that existing air compressor exists.
To achieve these goals, the piston valve type oilless air compressor that the utility model provides comprises crankcase, connecting rod, cylinder and piston, and said connecting rod is connected with said piston to drive said reciprocating motion of the pistons; Wherein, Said crankcase is provided with suction port, and said piston is tubbiness, and the diapire of said piston is provided with inlet hole; And the diapire of said piston is provided with first check valve sheet of the unidirectional inflow gas of the said inlet hole of control; The epimere of said cylinder interior is provided with check valve sheet, and said check valve sheet is provided with air outlet hole, and said check valve sheet is provided with second check valve sheet of the unidirectional eluting gas of the said air outlet hole of control; On the said cylinder head sidewall above the said check valve sheet, be provided with an independent air outlet.
According to a kind of preferred implementation of above-mentioned piston valve type oilless air compressor, wherein, said inlet hole is four, and said first check valve sheet is cross.
According to a kind of preferred implementation of above-mentioned piston valve type oilless air compressor, wherein, said air outlet hole is five, and said second check valve sheet comprises two long valve blocks and a short valve block.
In model utility, charge air flow is via crankcase, through the check valve sheet of piston diapire; Again by Piston Compression, through check valve sheet output, so not only increased the capacity of intake duct, air outlet flue; And can cool off crankcase; It is thus clear that accessory intensity, life-saving, reduction noise, no oil cooling can effectively be raised the efficiency, improved to the utility model but, realized energy-conserving and environment-protective.

Fig. 2 is the piston of the utility model preferred embodiment and the structural representation of first check valve sheet;
Fig. 3 is the structural representation of the check valve sheet and second check valve sheet of the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.
Fig. 1 schematically shows the structure of the utility model preferred embodiment, and shown in it, this preferred embodiment comprises crankcase 6, connecting rod 5, cylinder 4 and piston 3.The upper end of cylinder 4 is provided with its cylinder head 1, and the lower end is connected with crankcase 6.Connecting rod 5 is connected with driven plunger 3 to-and-fro motion in cylinder 4 with piston 3.Crankcase 6 is provided with suction port with input air.Piston 3 is tubbiness, and the diapire of piston 3 is provided with inlet hole (being covered by first check valve sheet 31), and the diapire of piston 3 is provided with first check valve sheet 31 of the unidirectional inflow gas of control inlet hole.Cylinder 4 inner epimeres are provided with check valve sheet 2, and check valve sheet 2 is provided with air outlet hole 21, and check valve sheet 2 is provided with second check valve sheet 22,24 of control air outlet hole 21 unidirectional eluting gass.On 4 sidewalls of the cylinder above the check valve sheet 2, be provided with air outlet 41.
In this preferred embodiment, the inwall of piston 3 is provided with wrist pin 32, and the end of connecting rod 5 is connected with wrist pin 32 through the bearing (not shown).
As shown in Figure 2; In this preferred embodiment, the inlet hole on the diapire of piston 3 is four, and first check valve sheet 31 is cross; Four inlet holes are positioned at four ends of first check valve sheet 31, and the center of first check valve sheet 31 is fixed in outside the diapire of piston 3 through bolt 33.
As shown in Figure 3; In this preferred embodiment, air outlet hole 21 is five, wherein four four angles that are positioned at symmetry; Another is positioned at the center; Second check valve sheet 22,24 is respectively two long valve blocks 24 and a short valve block 22, and long valve block 24 is fixed on the check valve sheet 2 through bolt 25, and short valve block 22 is fixed on the check valve sheet 2 through bolt 23.Each long valve block 24 is corresponding with two air outlet holes 21, and 22 air outlet holes 21 with the center of short valve block are corresponding.
