Abstract

The mechanism capable of preventing oil vomiting caused by emergency shutdown of the intelligent air compressor comprises an air inlet control valve, a compressor and a gas-liquid separator, the air inlet control valve is sequentially connected with the compressor and the gas-liquid separator, and the air inlet control valve comprises a valve body air bin, an air inlet adjusting valve plate and a one-way buffering mechanism. An air inlet is formed in the top of the valve body air bin, an air outlet is formed in the bottom of the valve body air bin and connected with the compressor, and an air inlet adjusting valve plate and a one-way buffering mechanism are sequentially arranged in the valve body air bin from top to bottom. When the air compressor unit is rapidly shut down in an abnormal state, as the internal pressure of the unit is high and the system pressure cannot be rapidly released, lubricating oil in the compressor unit can act in the one-way buffer mechanism through the valve body air bin and the internal air pressure, so that the buffer cavity is closed, the reverse stopping effect is achieved, and meanwhile the pressure self-control valve is rapidly opened; and the ultrahigh pressure is released in time, and the reverse oil vomiting phenomenon occurring when the unit is shut down abnormally can be well solved.

Description

Technical Field

[0001] The utility model relates to the field of air compressors, in particular to a mechanism capable of preventing an intelligent air compressor from vomiting oil during emergency shutdown. Background Art

[0002] At present, when the intelligent air compressor is running, Figure 1 As shown, the air passes through the air inlet pipe of the valve body air bin 1', the air inlet regulating valve plate 2', and then to the air outlet of the valve body air bin, and finally to the compressor for compression.

[0003] When the unit is shut down rapidly in an abnormal state, the lubricating oil inside the compressor will pass through the valve body air chamber 1'. Due to the very large recoil force, the air intake regulating valve 2' will be pushed open and finally flow upstream to form an oil vomiting phenomenon. The large impact force will have a great impact on the product quality, making it difficult to control the quality of the entire unit. Utility Model Content

[0030] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0031] Please refer to Figures 2 to 5 The utility model provides a mechanism for preventing an intelligent air compressor from vomiting oil during emergency shutdown, comprising an air intake control valve 1, a compressor 2 and a gas-liquid separator 3, wherein the air intake control valve 1 is connected to the compressor 2 and the gas-liquid separator 3 in sequence, and the air intake control valve 1 comprises a valve body gas bin 11, an air intake regulating valve plate 12 and a one-way buffer mechanism 14;

[0032] The top of the valve body air bin 11 is provided with an air inlet, the bottom of the valve body air bin 11 is provided with an exhaust port, and the exhaust port is connected to the compressor 2;

[0033] The air intake regulating valve plate 12 and the one-way buffer mechanism 14 are arranged in sequence from top to bottom in the valve body air chamber 11 .

[0034] Wherein, a partition plate 13 is provided at the bottom of the air inlet of the valve body air bin 11, and the partition plate 13 divides the bottom of the air inlet of the valve body air bin 11 into two buffer chambers, and the bottoms of the two buffer chambers are both provided with the one-way buffer mechanism 14;

[0035] When the air compressor unit is working normally, the gas first passes through the air filter and then through the air intake control valve 1. The gas inside the air intake control valve 1 passes through the air intake regulating valve plate 12, through the buffer chamber to the one-way buffer mechanism 14, and then to the exhaust port at the bottom of the valve body air bin 11, and finally to the compressor 2 for compression, enters the gas-liquid separator 3, and then supplies the gas to the outside;

[0036] When the air compressor unit shuts down quickly in an abnormal state, due to the high internal pressure of the unit, the system pressure cannot be released quickly. The lubricating oil inside the compressor 2 unit will pass through the valve body air chamber 11, and the internal air pressure will act on the one-way buffer mechanism 14, thereby closing the buffer chamber and playing a reverse cut-off role, which can well solve the reverse oil vomiting phenomenon that occurs when the unit is shut down abnormally.

[0037] In this embodiment, the one-way buffer mechanism 14 includes a flap 141, a rotating shaft 142 and a limiting plate 143;

[0038] The rotating shaft 142 is installed at the bottom of the partition plate 13;

[0039] The flap 141 is rotatably mounted on the rotating shaft 142, and the flap 141 can cover the bottom outlet of the buffer chamber;

[0040] The limiting plate 143 is disposed on one side of the rotating shaft 142 so that the flap 141 is kept perpendicular to the partition plate 13 under the action of gravity.

[0041] When the air compressor unit stops quickly in an abnormal state, due to the high internal pressure of the unit, the system pressure cannot be released quickly. The lubricating oil inside the compressor 2 unit will pass through the valve body air chamber 11, and the internal air pressure will act on the flap 141, which will flip upward to close the buffer chamber.

[0042] In this embodiment, a pressure automatic control valve 4 is installed on the gas-liquid separator 3. If the pressure detection element detects that the gas pressure exceeds the standard, the pressure automatic control valve 4 can be opened to quickly release the pressure. At the same time, the one-way buffer mechanism 14 in the intake control valve 1 can also play a reverse cut-off role to reduce the system impact force, which can well solve the reverse oil vomiting phenomenon that occurs when the unit is shut down abnormally.

[0043] The pressure self-control valve 4, also known as the pressure control valve, is an automatic regulating valve used to control fluid pressure. It monitors the pressure changes of the medium (such as gas, liquid) in the pipeline and automatically adjusts the valve opening to keep the medium flow and pressure within a predetermined range, thereby ensuring the stability and safety of the production process; the model of the pressure self-control valve 4 is S30P5.0B.

[0044] The working principle of the utility model is as follows:

[0045] When the air compressor unit shuts down quickly in an abnormal state, due to the high internal pressure of the unit, the system pressure cannot be released quickly. The lubricating oil inside the compressor 2 unit will pass through the valve body air chamber 11, and the internal air pressure will act on the one-way buffer mechanism 14, thereby closing the buffer chamber and playing a reverse cut-off role, which can well solve the reverse oil vomiting phenomenon that occurs when the unit is shut down abnormally.

[0046] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to software and methods.

Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
