Technical Field

The invention belongs to the technical field of vibration reduction and noise reduction, and particularly relates to a dual-channel inflation and deflation control unit for an air spring.

Background

The posture of the raft frame (or other vibration isolation platforms) can be adjusted by controlling the air inflation and deflation of the air springs, so that the vibration isolation device is ensured to be at the rated working height, and the optimal vibration isolation effect is achieved. The control system controls the air spring inflation and deflation through the electromagnetic valve, monitors the air pressure of the air spring in real time through the pressure sensor, but the electromagnetic valve and the pressure sensor are easily interfered and damaged by the severe environment on site, and in addition, the electromagnetic valve and the pressure sensor are dispersedly installed, so that the field installation and the later maintenance are not facilitated.

The invention aims to provide an air spring dual-channel inflation and deflation control unit, which can ensure that an air spring control system can work safely for a long time, and an integrated dual-channel inflation and deflation control unit saves space, belongs to a modular design and is convenient for field installation and maintenance.

The technical scheme for realizing the invention is as follows:

a dual-channel air charging and discharging control unit for an air spring mainly comprises a box body, a valve block, an electromagnetic valve, a pressure sensor, an air path joint and an electric connector;

the box body is arranged on the valve block; the valve block is provided with a path of air inlet channel, a path of air charging channel and a path of air discharging channel, the electromagnetic valve is arranged on the valve block, the two air charging channels are respectively communicated with the air inlet channel through the electromagnetic valve, and the two paths of air discharging channels are respectively communicated with the two air charging channels through the electromagnetic valve; the pressure sensor is arranged on the valve block and used for detecting the pressure of the two inflation channels;

signals and power supplies of the electromagnetic valve and the pressure sensor are connected with the outside through an electric connector arranged on the box body; and air path joints are arranged at the outlets of the two inflation channels and are connected with the air spring pipeline through the air path joints.

Furthermore, the valve block is provided with a threaded hole for fixing the valve block with the outside.

Furthermore, the electromagnetic valve is arranged on the valve block through the valve plate.

Advantageous effects

The first safety is good, and the protection level is high. The electromagnetic valve and the pressure sensor are completely arranged in the box body, the body is not in contact with the outside, and liquid inflow, heavy object impact and manual treading can be prevented.

And due to the second modular design, the installation, debugging and maintenance are convenient. The control unit is connected with the outside through the aerial plug and the threaded gas circuit connector, the models of the internal electromagnetic valve and the pressure sensor are consistent, the control unit is integrated in a modularized mode, and field installation and debugging and later maintenance are facilitated. .

And the third section saves space. Five air holes are formed in the valve block, and the two inflation channels share the air inlet channel, so that independent inflation and deflation of the two air springs can be realized.
