Description

一种四状态可调节式气路结构
技术领域
本发明属于一种储气式气动执行机构，特别涉及一种四状态可调节式气路结构。
背景技术
目前，在电力、石油和化工等领域的某些特殊场合中，很多情况下需要控制阀门在断液压源时，阀门能够迅速关闭。但是普通的液压机构不仅难以满足这个需求，还伴随着一系列的诸如损耗大、效率低、发热大、安全防护等问题。
发明内容
本发明的目的就是针对上述现有技术存在的问题，提供一种四状态可调节式气路结构，达到作业快速可靠、动力损耗小、效率高、安全性好的特点。
本发明的目的是通过以下技术方案实现的：气源经由单向阀分别与贮气罐和二位三通电磁阀A的a1端口连通，所述的二位三通电磁阀A的c1端口和b1端口分别与二位三通电磁阀B的c2端口和排气孔连通，所述的二位三通电磁阀B的a2端口和b2端口分别与二位三通电磁阀C的b3端口和节流阀一端口连通，所述节流阀的另一端口与二位三通电磁阀C的a3端口连通，所述的二位三通电磁阀C的c3端口与气罐连通，至此构成一种四状态可调节式气路结构。
与现有技术相比，本发明的特点是：
以空气为介质，利用空气的压缩性，实现集中供气，机械设计及维护大大简化；可实现工作速率的智能控制。
本发明的有益效果是：
气动装置结构简单、轻便、安装维护简单；不易燃烧，可在高温场合使用，故使用安全；排气处理简单，不污染环境，成本低；输入及输出力矩和工作速度的容易调节比液压和电气方式的动作速度快；可靠性高，使用寿命长；可实现缓冲。对冲击负载和过负载有较强的适应能力；在一定条件下，可使气动装置有自保持能力；适合远距离输送。

图5是本发明作业时缓慢排气原理图
图1中：1气源2单向阀3贮气罐4二位三通电磁阀A5排气孔6二位三通电磁阀B7节流阀8二位三通电磁阀C9气罐
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。
