The quantity of described electromagnetic valve is two, is respectively an electromagnetic valve and No. two electromagnetic valves, and the quantity of flow regulating valve is two, is respectively a flow regulating valve and No. two flow regulating valve; The admission port of a described electromagnetic valve, No. two electromagnetic valves all communicates with levelling valve, air extractor duct communicates with an air bellow, No. two air bellows respectively, the hot-wire coil of an electromagnetic valve, No. two electromagnetic valves all is connected with switch, and is connected with flow regulating valve No. two in the exhaust ports that the exhaust ports of an electromagnetic valve is connected with a flow regulating valve, No. two electromagnetic valves.
Described flow regulating valve is manual flow regulating valve or automatically controlled flow regulating valve.
Described electromagnetic valve has three control positioies, is respectively the air inlet position, stops holding position and exhaust position.
The two ends of described switch are respectively arranged with indicator lamp and power supply.
Compared with prior art, the beneficial effects of the utility model are:
1, because a kind of air suspension height control system of the utility model inserts flow regulating valve at the electromagnetic valve exhausr port, be that flow regulating valve is connected with the electromagnetic valve exhausr port, the electromagnetic valve two ends are connected with air bellow with levelling valve respectively, by regulating the aperture of flow regulating valve, the control electromagnetic valve exhaust velocity, guarantee trailer slowly, at the uniform velocity descend, will be reduced to minimum to the impact of vehicle body and air-path control system.
2, because the flow regulating valve in a kind of air suspension height control system of the utility model is manual flow regulating valve, the driver can rule of thumb oneself regulate, and guarantees the steady decline of trailer.
3, because the flow regulating valve in a kind of air suspension height control system of the utility model is automatically controlled flow regulating valve, and the driver can control the reduction of speed of trailer at operator's compartment, easily.
