Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

According to the accompanying drawings 1 and 2, the multifunctional integrated controller of the air circuit of the present utility model includes a valve body 1, an air filter 2, a discharge valve 3, a shuttle valve 4, a flow-limiting regulating valve 5, and a control solenoid valve. 6 and intake valve 7, wherein the air filter 2 is composed of a filter seat 21, a filter element 22 installed on the filter seat 21 and a valve 23 located at the bottom of the filter seat 21, and its main function is to filter air fine dust to ensure clean air in the air circuit control system; the relief valve 3 is composed of a piston 31 and a sealing ring 32, which acts as a pressure relief in the air circuit controller; the shuttle valve 4 includes a valve seat 41, a valve core 42 and a seal Pad 43, the shuttle valve 4 is connected with the interface 8 of the pressure sensor, which plays the role of transmitting signals; the flow-limiting regulating valve 5 is a bolt, and the gas flow of the relief valve 3 is adjusted by rotating the bolt. The shuttle valve 4, the air filter 2, the discharge valve 3 and the flow-limiting regulating valve 5 are sequentially installed in the valve body 1, and are connected through passages in the valve body 1. The valve body 1 is respectively provided with an air source inlet 9 connected with the air filter 2 and the shuttle valve 4, a discharge valve outlet 10 connected with the flow limiting regulating valve 5, an air inlet 11 of the control solenoid valve, Control solenoid valve exhaust port 12, pressure sensor interface 8 and signal output port 13.

When the compressor starts, the control solenoid valve is in the closed state, and the compressed gas enters the gas source inlet 9, and after being filtered by the air filter 2, the discharge valve 3 and the flow-limiting adjustment are adjusted by rotating the flow-limiting regulating valve 5. The size of the connecting channel between the valves 5 controls the gas discharge speed, and finally the gas is discharged from the discharge port 10 of the relief valve, which is started in the unloaded state; when the gas pressure in the compressor rises to the loading set value , the control solenoid valve 6 is energized and opened, and the compressed gas enters the control solenoid valve exhaust port 12 and the signal output port 13 through the control solenoid valve inlet 11. Since the right end face of the piston 31 of the relief valve 3 is larger than the left end face, there is pressure Poor, the piston 31 moves to the left to close the relief valve 3, the relief valve 3 stops pressure relief, and at the same time the compressed gas outputs a signal to the intake valve 7 through the signal output port 13, and the intake valve 7 is opened, and it is in a load state at this time; When the gas pressure in the compressor rises to the set value for unloading, the control solenoid valve 6 is de-energized and closed, the air inlet 11 of the control solenoid valve and the exhaust port 12 of the control solenoid valve are blocked, and the signal output port 13 has no signal output at the same time. The gas valve 7 is closed, the piston 31 of the relief valve 3 moves to the right, the relief valve 3 is opened and the gas is discharged through the action of the flow-limiting regulating valve 5, and it is an unloading state at this time.

The valve body 1 is provided with a valve cover 14 connected to the control solenoid valve 6, the control solenoid valve air inlet 11, the control solenoid valve exhaust port 12 and the signal output port 13 are arranged on the valve cover 14, by replacing valves with different structures The cover 14 changes the connection relationship between the control solenoid valve 6 and the valve body 1, and changes the settings of the control solenoid valve air inlet 11 and the control solenoid valve exhaust port 12. As shown in accompanying drawing 3, by replacing the bonnet 14, the installation method of the control solenoid valve 6 is changed to a pipeline type control solenoid valve 6, and the exhaust port 12 of the control solenoid valve is arranged on the control solenoid valve 6, and the control solenoid valve The exhaust port 12 communicates with the left end interface 15 on the valve body 1 with a pipeline. Through the change of the structure of the valve cover 14, the installation position of the air circuit multifunctional integrated controller of the utility model in the compressor is more flexible, and the space utilization rate in the compressor is improved.

The gas circuit multifunctional integrated controller of the utility model is not only suitable for the gas circuit control of the gas compressor, but also suitable for the gas circuit control of other purposes.
