Technical Field
The invention belongs to the field of air valves, and particularly relates to an intelligent air valve of an air compressor based on energy collection.
Background
Among the faults occurring in the operation process of the air compressor, the abnormal shutdown duty ratio of the air compressor is the largest because of the fault of the air valve. The air valve structure is finer than other air compressor components, and is easier to damage in the repeated impact process of the valve plate and the valve seat, so that the working state of the air valve structure can directly influence the working reliability and economy of the air compressor. It is counted that about 60% of all air compressor outages are due to valve failure. The working environment of the air valve is severe, the working temperature of the exhaust valve can reach about 200 ℃, and the working pressure of the high-pressure compressor can reach tens of megapascals. Meanwhile, the air valve is high in opening and closing frequency, for example, when the air compressor rotates at 1000r/min, the air valve is opened and closed 16.6 times per second, and the valve plate is easy to be damaged and broken due to high-strength movement of the valve plate and impact when the valve seat is attached. Carbon deposition and external foreign matter inhalation generated in the compressor can also cause blockage of the air valve, so that the air valve is opened and closed untimely or not in place, and the exhaust pressure and the working efficiency of the air compressor are affected. In the traditional air valve fault removal process, the air valve can be primarily judged through pressure and temperature changes, but only a certain level of air valve can be positioned, and for a large-displacement air compressor, the number of air valves is large, and the specific faulty air valve is difficult to accurately position.

The valve seat 2 is internally provided with a hole cavity capable of allowing gas to circulate, the valve seat 2 is arranged in the hole cavity, the valve seat 2 is provided with a hole communicated with the hole cavity, the valve plate 3 is arranged at the bottom of the valve seat 2 and can open and close the hole, when the valve plate 3 butts against the hole, the valve seat 2 cuts off the hole cavity to prevent gas from circulating, the effect of closing the air valve is achieved, and when the valve plate 3 breaks away from the hole, the gas circulates through the hole of the valve seat 2, and the effect of opening the air valve is achieved.
In this embodiment, the connection surface between the valve plate 3 and the air hole is in a smooth spherical shape, and the design of the spherical surface can enable the valve plate 3 to be in better airtight contact with the air hole on the valve seat 2.
The compression spring 4 is arranged below the valve plate 3, the top end of the compression spring 4 is propped against the valve plate 3, and the bottom end of the compression spring 4 is propped against the bottom of the cavity.
For the air suction valve, when the air compressor starts to suck air, the pressure of the corresponding space below the valve plate 3 is reduced, the valve plate 3 generates a downward acting force under the action of the upper atmospheric pressure, and when the pressure is greater than the elastic force of the compression spring 4, the valve plate 3 moves downward, and the air suction valve is opened to start air intake; after the air compressor is sucked, the air compressor enters a compression stage, the pressure in the air cylinder gradually rises, and when the pressure below the valve plate 3 is larger than the pressure above the valve plate, the valve plate 3 moves upwards and impacts the valve seat 2 to be attached to the valve seat 2, so that the air hole is closed. For the exhaust valve, the structure is approximately the same, but the installation positions of the compression spring 4 and the valve plate 3 are different, the movement is opposite, the valve plate 3 is closed in the process of air suction, the valve seat 2 is impacted, and the valve plate 3 is opened in the process of air exhaust.

When the air compressor works continuously, the valve plate 3 and the valve seat 2 generate continuous impact, for example, for a 1500r/min air compressor, the impact is generated 25 times per second, and the high-frequency movement generates a large amount of alternating current electric energy, and meanwhile, continuous electric signals are generated along with the alternating current electric energy, and the generation of the electric signals also characterizes the closing of the air valve. If the air valve breaks down, such as breakage and blockage, the closing time and the closing impact of the air valve change, the pulse time interval changes and the pulse time interval changes on the electric signals, the signals are input to the wireless transmitting module 6, the wireless transmitting module 6 is in wireless communication with the wireless receiving module 7, the collected electric signals are sent to the wireless receiving module 7, the wireless transmitting module 6 and the wireless receiving module 7 adopt a Zigbee communication protocol, the wireless transmitting module is further provided with an AD converter, the AD converter can convert the received analog signals of the valve seat 2 into digital signals and then send the digital signals to the wireless receiving module 7, the wireless receiving module 7 sends the received signals to the terminal 8 for analysis, an operator can realize the operation state of the monitoring valve plate 3 on the terminal 8, the air valve can be rapidly and directly positioned once the air valve breaks down, maintenance and replacement can also judge the degradation process of the air valve according to the change of the signals, the necessary information is provided for the air valve life prediction, the stable operation of machine equipment can be avoided in advance.
