Screw type air compressor air inlet valve with features of precise control of opening degree and driving and quick response

Abstract

The screw air compressor precisely controls the quick-response intake valve. The drive controller 3 is installed on the side of the valve body 5, and the butterfly valve 6 is installed on the upper part of the intake port 1. The butterfly valve 6 is connected to the drive controller with 3 axes. A hammer type check valve 7 is installed under the inner butterfly valve 6, a vent valve 4 is installed on the valve body 5, and the drive controller 3 and the vent valve 4 are connected with the control system. The air intake volume is adjusted by using the drive controller in cooperation with the vent valve and the heavy hammer check valve. All functional structural channels are integrated in the air inlet and air outlet passages, reducing leakage points, flexible opening and closing actions, and rapid system response. , use the drive controller to accurately and timely control the opening of the butterfly valve, use the vent valve to balance the pressure drop in the system, reduce power consumption and noise during unloading, increase the flow rate of the passing air, increase the flow rate, and reduce the loading time of the screw compressor , which saves the amount of controlled air consumption and realizes the reduction of motor power consumption and energy saving.

Description

technical field [0001] The invention relates to an F04C29 / 12 working fluid suction or discharge device in the IPC classification, in particular to a screw-type air compressor opening precision driving control fast-response intake valve. Background technique [0002] The intake valve is the breathing port of the air compressor. Ordinary air enters the intake valve and then goes to the compressor head, where it is compressed to produce compressed gas. The intake valve can control the loading and unloading of the air compressor and the size and flow of the air pressure. It is a major component of the air intake control system of the air compressor. [0003] The intake valve with a control mechanism includes an intake control valve. The intake control valve is mainly composed of a valve body, a valve plate or a piston valve, a cylinder, a proportional regulating valve, and a solenoid valve. The components are different according to the matching power. Its side is equipped with ...

AI Technical Summary

Problems solved by technology

[0010] Most of the intake valves currently on the market are controlled by servo cylinders, which cannot achieve continuous and stable supply. They will only be unloaded after the load is full, and then start to load again. This process is continuously cycled. When loading, it impacts the power grid, and when unloading, it is wasted.
