Double-channel inflation and deflation control unit for air spring

Abstract

The invention discloses a double-channel inflation and deflation control unit for an air spring. The double-channel inflation and deflation control unit mainly consists of a box body, a valve block, electromagnetic valves, a pressure sensor, air path joints and an electric connector, wherein the box body is mounted on the valve block; the valve block is provided with an air inlet channel, two air inflation channels and two air exhaust channels; the electromagnetic valves are mounted on the valve block; the two air inflation channels are communicated with the air inlet channel through the electromagnetic valves respectively; the two air exhaust channels are communicated with the two air inflation channels through the electromagnetic valves respectively; the pressure sensor is mounted on the valve block and used for detecting the pressure of the two inflation channels; signals and power supplies of the electromagnetic valves and the pressure sensor are connected with the outside through the electric connector installed on the box body; the air path joints are arranged at the outlets of the two inflation channels; and the two inflation channels are connected with an air spring pipeline through the air path joints. According to the control unit, an air spring control system can work safely for a long time, and the space is saved through the integrated double-channel inflation and deflation control unit.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction and noise reduction, and in particular relates to an air spring dual-channel inflation and deflation control unit. Background technique [0002] By controlling the inflation and deflation of the air spring, the attitude of the raft (or other vibration isolation platform) can be adjusted, so as to ensure that the vibration isolation device is at the rated working height, so that it can exert the best vibration isolation effect. The control system controls the inflation and deflation of the air spring through the solenoid valve, and monitors the air pressure of the air spring in real time through the pressure sensor. However, the solenoid valve and pressure sensor are susceptible to interference and damage from the harsh environment on site. In addition, the scattered installation of solenoid valves and pressure sensors is not conducive to On-site installation and post-maintenance. Con...
