Technical Field
The utility model belongs to the technical field of air compressor, especially, relate to an air compressor's gas accuse device.
Background
Traditional air compressor is on pneumatic control, and the compressor will stop the compression when gas pitcher pressure is sufficient, and the motor also can stop frequent motor that stops air compressor that stops and stop and open and motor damage when can be easy, and the life-span subtracts the weak point, and when the long-time low discharge output of gas pitcher was gaseous, the opening of motor was very obvious stopped.
Therefore, it is necessary to invent an air control device of an air compressor.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides an air compressor's gas accuse device to the compressor that proposes in solving the background art when gas pitcher pressure is sufficient can stop the compression, and the motor also can stop frequent motor that opens air compressor that stops and stop damages when can be easy, and the life-span subtracts the weak point, and when the long-time low discharge output of gas pitcher was gaseous, opening of motor was especially obvious. The air control device of the air compressor comprises a shell, wherein an unloading air pressure control assembly is arranged at the upper end of the shell, a concentric valve is arranged at the lower end of the middle of the shell, an air suction port is formed in one side of the shell, and an air exhaust port is formed in the other side of the shell.
As a further technical scheme of the utility model, off-load air pressure control assembly is equipped with and is equipped with off-load air inlet on cylinder and the cylinder, off-load air inlet lower extreme is equipped with the off-load air cavity, be equipped with the piston in the off-load air cavity, and piston one side is equipped with O type circle and spring.
As a further technical scheme of the utility model, the piston bottom is connected with the piston rod, be equipped with the aperture of admitting air on the piston rod.
As a further technical scheme of the utility model, off-load air pressure control assembly is equipped with the connecting seat, and connecting seat connection off-load air pressure control assembly and casing.
As a further technical scheme of the utility model, be fixed connection between piston and the piston rod, the induction port is inside to be round, and moves towards to be the L type, piston rod bottom diameter matches with the internal diameter of induction port.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses in, through being provided with off-load atmospheric control subassembly, when gas pitcher pressure grow gradually, gas pressure promotes the piston and makes the piston rod close the induction port, through reserving the inlet aperture on the piston rod for in the operational environment of miniflow, the compressor also can be when the induction port is closed through the space on the inlet aperture with gaseous from the induction port suction.

Detailed Description
The invention is further described below with reference to the accompanying drawings:
the embodiment is as follows:
as shown in figure 1
The utility model provides an air compressor's gas accuse device is equipped with casing 1, 1 upper end of casing is equipped with off-load air pressure control assembly, and 1 middle part lower extreme of casing is equipped with concentric valve 3, 1 one side of casing is equipped with induction port 4, 1 opposite side of casing is equipped with gas vent 5.
In this embodiment, the unloading air pressure control assembly is provided with an air cylinder 12, an unloading air inlet 6 is arranged on the air cylinder 12, an unloading air cavity 11 is arranged at the lower end of the unloading air inlet 6, a piston 7 is arranged in the unloading air cavity 11, and an O-shaped ring and a spring are arranged on one side of the piston 7.
By adopting the technical scheme, the bottom of the piston 7 is connected with the piston rod 8, and the piston rod 8 is provided with the small air inlet hole 10.
In this embodiment, the unloading air pressure control assembly is provided with a connecting seat 9, and the connecting seat 9 is connected with the unloading air pressure control assembly and the housing 1.
By adopting the technical scheme, the piston 7 is fixedly connected with the piston rod 8, the inside of the air suction port 4 is circular and is L-shaped, and the diameter of the bottom of the piston rod 8 is matched with the inner diameter of the air suction port 4;
principle of operation
The utility model discloses, the gas holder is connected to off-load gas air inlet 6, reaches the setting value gradually as gas holder pressure, and gas holder pressure passes through off-load air cavity 11 and promotes piston 7, makes piston rod 8 promote closing of induction port 4, because the compressor is still normally working, and induction port 4 can not be sealed completely, and after induction port 4 was closed by piston rod 8, the required gas of compressor work goes out from the inlet aperture 10 on the piston rod 8 and gets into.
Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
