具体实施方式
下面结合附图对本发明具体实施例作进一步详细描述。
如图1所示，一种四状态可调节式气路结构，气源1经由单向阀2分别与贮气罐3和二位三通电磁阀A4的a1端口连通，所述的二位三通电磁阀A4的c1端口和b1端口分别与二位三通电磁阀B6的c2端口和排气孔5连通，所述的二位三通电磁阀B6的a2端口和b2端口分别与二位三通电磁阀C8的b3端口和节流阀7一端口连通，所述节流阀7的另一端口与二位三通电磁阀C8的a3端口连通，所述的二位三通电磁阀C8的c3端口与气罐9连通。
作业过程如下
图2是迅速充气示意图。在所述的一种四状态可调节式气路结构中，当二位三通电磁阀A4上电时，a1端口导通，b1端口截止，此时如果二位三通电磁阀B6上电，二位三通电磁阀C8断电，即a2、b3端口导通，b2、a3端口截止，则外界空气依次通过气源1、单向阀2、二位三通电磁阀A4、二位三通电磁阀B6和二位三通电磁阀C8导入气罐9，气路压力迅速增大，气罐9迅速贮存大量压缩空气。单向阀2和贮气罐C3的作用是防止外界输入空气发生扰动，导致气路内气压骤然下降。
图3是缓慢充气示意图。在所述的一种四状态可调节式气路结构中，当二位三通电磁阀A4上电时，a1端口导通，b1端口截止，此时如果二位三通电磁阀B6断电，二位三通电磁阀C8上电，即a3、b2端口导通，a2、b3端口截止，则外界空气依次通过气源1、单向阀2、二位三通电磁阀A4、二位三通电磁阀B6、节流阀7和二位三通电磁阀C8缓慢导入气罐9，气路压力逐渐增大，气罐9缓慢贮存大量压缩空气。
图4是迅速排气示意图。在所述的一种四状态可调节式气路结构中，当二位三通电磁阀C8断电时，b3端口导通，a3端口截止，此时如果二位三通电磁阀B6上电，即a2端口导通，b2端口截止，气罐9里的压缩空气通过二位三通电磁阀C8的b3端口导通至二位三通电磁阀B6的a2端口，再通过二位三通电磁阀B6的c2端口导通至二位三通电磁阀A4的c1端口，此时二位三通电磁阀A4断电，b1端口导通，a1端口截止，气路气体迅速通过排气孔5排出。
图5是缓慢排气示意图。在所述的一种四状态可调节式气路结构中，当二位三通电磁阀 C8上电时，a3端口导通，b3端口截止，此时如果二位三通电磁阀B6断电，即b2端口导通，a2端口截止，气罐9里的压缩空气从二位三通电磁阀C8的a3端口经过节流阀7导通至二位三通电磁阀B6的b2端口，再通过二位三通电磁阀B6的c2端口导通至二位三通电磁阀A4的c1端口，此时二位三通电磁阀A4断电，b1端口导通，a1端口截止，气路气体缓缓通过排气孔5排出。
