The invention relates to the technical field of air valves, and provides a cab air suspension height adjusting valve which comprises a valve body and an electromagnetic valve assembly, and the valve body is provided with an air outlet channel and a first exhaust hole; the electromagnetic valve assembly is telescopically arranged in the air outlet channel, and when the electromagnetic valve assembly is not powered on, the first end of the electromagnetic valve assembly is located at the first position, and the first exhaust hole is blocked from the air outlet channel; when the electromagnetic valve assembly is powered on, the electromagnetic valve assembly shrinks, the first end of the electromagnetic valve assembly is located at the second position, the first exhaust hole communicates with the air outlet channel, and air in the air spring is exhausted through the first exhaust hole. According to the air suspension height adjusting valve for the cab, the electromagnetic valve assembly is contracted when powered on to avoid the position of the first exhaust hole, so that the first exhaust hole is communicated with the air outlet channel, air in the air spring can be quickly exhausted, the height of the cab is reduced, a driver and passengers can get on and off a vehicle conveniently, and convenient conditions are provided for the driver and passengers to get on and off the vehicle.
本发明涉及空气阀技术领域,提供一种驾驶室空气悬挂高度调节阀,包括:阀体和电磁阀总成,阀体设有出气通道和第一排气孔;电磁阀总成可伸缩地设置于出气通道内,在电磁阀总成处于未通电的情况下,电磁阀总成的第一端处于第一位置,第一排气孔与出气通道阻断;在电磁阀总成处于通电的情况下,电磁阀总成收缩,电磁阀总成的第一端处于第二位置,第一排气孔与出气通道连通,空气弹簧中的气体经第一排气孔排出。上述的驾驶室空气悬挂高度调节阀,利用电磁阀总成在通电时收缩,避开第一排气孔的位置,从而使第一排气孔与出气通道连通,可快速将空气弹簧中的气体排出,使驾驶室高度下降,便于驾乘人员上下车,为驾乘人员上下车提供了便利条件。
