Detailed Description
The preferred embodiments of the present invention are described in more detail below, however, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The compressor used in the current stage is designed in an air pump mode in consideration of energy conservation and efficiency improvement. The compressor adopting the air pump mode design has a disadvantage in operation in the base station, the rigidity of the valve plate of the compressor meets the application in the air pump mode, but when the compressor is switched to the compression mode, because the operation condition is heavy, the impact force of the air flow under the high compression ratio state on the valve plate is larger, the valve plate is easy to break, and the overall reliability is low. When the compressor designed in the air pump mode runs for a long time under the compression working condition under the conditions of high temperature and high pressure in summer, the reliability of the compressor cannot be well ensured.
Example 1:
to solve the above problems, embodiment 1 provides an exhaust structure, which is provided with two exhaust holes, so that only one of the two exhaust holes is always in a normal working state under different pressures, and two operation modes can be considered simultaneously.
As shown in fig. 1-3, the exhaust structure comprises an upper flange 1 and an exhaust component 2, wherein an exhaust port communicated with the upper flange 1 is arranged on the upper flange;
two valve slots are arranged on the upper flange 1 at intervals, and an exhaust port is arranged in each valve slot;
the exhaust assembly 2 comprises a sealing plate 8 for sealing the valve groove and a valve plate capable of sealing the exhaust port, the sealing plate 8 covers the upper flange 1 to seal the valve groove, the sealing plate 8 is locked with the upper flange 1 through screws, and in order to ensure the exhaust effect, the sealing treatment is carried out between the sealing plate 8 and the upper flange, such as a sealing ring is arranged or a seam is filled with sealant;
the sealing plate 8 is provided with a two-position one-way valve 9, two inlets of the two-position one-way valve 9 are respectively communicated with two valve grooves, and an outlet 14 of the two-position one-way valve 9 is communicated with an external cavity;
the rigidity of the valve plates arranged in the two valve grooves is different;
the rigidity of the valve plate with low rigidity is not more than the minimum exhaust pressure of a low working condition, and the rigidity of the valve plate with high rigidity is not more than the minimum exhaust pressure of a high working condition and is more than the maximum exhaust pressure of the low working condition;
the low working condition exhaust pressure and the high working condition exhaust pressure are correspondingly set by technicians in the field according to the specific model of the compressor, and the low working condition exhaust pressure is the exhaust pressure in a high-pressure-difference low state; the high-working-condition exhaust pressure is the exhaust pressure under the high-low pressure difference large state.
As shown in fig. 7, the exhaust principle of the compressor is:
the effective compression space in the compression cavity of the air cylinder 19 of the compressor is crescent formed by the inner wall of the air cylinder 19 and the outer wall of the roller 21, when the compressor starts to work, the rotor of the motor part 24 is connected with the long shaft of the crankshaft 18 of the pump body assembly 25, the crankshaft 18 drives the roller 21 to eccentrically rotate in the compression cavity, and the slide sheet 22 reciprocates in the slide sheet groove along with the roller 21; the sliding vane 22 of the cylinder 19 separates the crescent space into an exhaust high-pressure cavity and an intake low-pressure cavity, when the exhaust pressure reaches a certain degree, namely, the exhaust pressure is greater than the rigidity of the valve plate, the valve plate is opened, and the exhaust system on the upper flange 1 on the cylinder 19 starts to work.
When the valve is used, if the high-low pressure difference is low, the exhaust pressure of the upper flange 1 is smaller, and the exhaust pressure is only larger than the valve plate with low rigidity and smaller than the valve plate with high rigidity. The exhaust hole at the valve plate with low rigidity starts to work, at this time, the valve of the two-position one-way valve 9 is pushed to the valve plate side with high rigidity by the gas pressure, at this time, the compressor starts to work in the air pump mode, as shown in fig. 6.
When the valve is used, if the high-low pressure difference is large, the exhaust pressure of the upper flange 1 is gradually increased until the exhaust pressure is larger than the valve plate with high rigidity. The exhaust holes at the valve plates with low rigidity are opened to work first, the valves are pushed to the valve plate side with high rigidity under the action of gas pressure, when the exhaust pressure reaches the compression mode, the exhaust holes at the valve plates with high rigidity start to work, at the moment, both the valve plates start to work, as the gas pressure at the valve plates with high rigidity is greater than that at the valve plates with low rigidity, the valves are pushed to the valve plate side with low rigidity, at the moment, the compressor starts the compression mode to work, as shown in fig. 5.
No matter under what kind of operating condition is in the compressor, behind the discharge port was opened to the valve block, exhaust subassembly 2 jointly constitutes a new exhaust system with last flange 1, and the compressor that possesses this exhaust structure can perfectly compromise the different operating condition of high-low pressure difference, raises the efficiency, reduce cost. For society, the energy consumption can be reduced, the energy can be saved, and a contribution is made to sustainable development.
In this embodiment, one end of the valve plate covers the exhaust port, and the other end of the valve plate is locked in the valve groove, and more specifically, the valve plate can be fixed in the valve groove through the valve rivet 7.
In this embodiment, one of the two valve slots is an air pump mode valve slot 3, and the other is a compression mode valve slot 5, the first valve plate 4 with low rigidity is installed in the air pump mode valve slot 3, and the second valve plate 6 with high rigidity is installed in the compression mode valve slot 5.
In this embodiment, the sealing plate 8 is provided with a first inlet 10 communicating with the air pump mode valve spool 3 and a second inlet 11 communicating with the compression mode valve spool 5, and the first inlet 10 and the second inlet 11 are respectively connected to two inlets of the two-position one-way valve 9.
In this embodiment, one end of the valve spool is a large end, the other end is a small end, and the exhaust port is disposed at the large end of the valve spool.
This exhaust structure controls two gas vents respectively through two valve blocks that rigidity is different, and two gas vents realize two-position one through a valve body, guarantee that two exhaust holes only are in normal operating condition all the time under the pressure of difference, can compromise two kinds of operational modes simultaneously, make compressor power reduce to improve the effect of compressor efficiency, improve the operational reliability.

when the compressor is not operated and the spring 16 is not stressed, the valve block 15 is positioned in the middle of the valve cavity 13 under the action of the spring 16, and the outlet 14 is closed by the valve block 15; the outlet 14 can be opened only by pushing the valve block 15 to move under the action of the exhaust pressure when the compressor is running, thus forming a complete exhaust system.
