Description

工作缸的速度控制装置
技术领域：
本发明与压力缸的速度控制调节装置有关。
背景技术：
压力缸的速度控制回路包括介质、介质控制回路旁路节流控制回路、串并联同步控制回路。这些回路需要有较复杂的多个元件构成，成本高，控制精度差。
发明内容：
本发明的目的是提供一种结构简单、所需元件少、成本低廉、控制精度高的工作缸的速度控制装置。
本发明是这样实现的：
本发明工作缸的速度控制装置的工作缸的进、出介质回路与二位或三位四通换向阀连接，工作缸的进介质回路或/和出介质回路上有差流可调梭阀，差流可调梭阀的壳体上有两个端口位于梭腔的轴线上，梭腔的外壁与壳体之间有旁通道，梭芯位于梭腔内，梭腔两端与调节件相对。
工作缸为单缸或双缸或单作用缸或双作用缸。
工作缸为串联的双缸，双缸的活塞位于同一活塞杆的两端，双缸的一端与梭式三通分流调节阀的端口A连接，分流调节阀的端口B与二位四通换向阀的介质入口端连接，端口C与差流可调梭阀的一端口和二位四通换向阀的位介质出口端连接，差流可调梭阀的另一端口与双缸的另一端连接，梭式三通分流调节阀的端口A、C位于其梭腔的轴线上，端口B与梭腔的一侧壁相对，梭腔两端与调节件相对。
工作缸出介质回路与进介质回路的连接管路上有两个串联的差流可调梭阀，两个差流可调梭阀的相连端口与二位或三位四通换向阀的介质入口端连接。
工作缸为并联的单缸，每个缸的进介质回路上各有一个单独的差流可调梭阀。
本发明结构简单，制造容易，成本低廉，利用差流可调梭阀控制工作缸进出口的流量和阻抗，由于差流可调梭阀具有双向节流功能，可简化回路，提高精度。双缸工作时无须平衡阀，也可利用流体介质自身能量对工作缸驱动的阀门的启闭进行自力式操作，可控制球阀、蝶阀、平板阀，广泛应用于天然气，石油、液化气、石化、化工、水电及环保行业的管道系统，起接通和截断管道输送介质的作用。本发明的控制装置具有如下优点：
安全可靠：多种梭阀与控制系统结合，可保证压力、流量、排气、补气、爆破、水击的快速调节和控制。故障时靠输送介质本体实现紧急切断。
经济实用：无需附加操作能源，无需昂贵而复杂的控制(如SCADA)系统，无需通讯网络等；投资少，成本低，制造简单，不怕干扰，不受电子战的影响。
适应性强：适应沙漠、地下、水下、森林等缺乏动力的恶劣影环境；适用于高温、高压、强腐蚀、有毒、放射性物、有害的介质传输系统。
兼容性好：梭阀可独立存在于现有任何技术系统中；可利用原有的通讯系统、伺服调节系统，实现在线无级调节(无需外设执行动力源)；也可与卫星系统(VSAT)、智能化集中控制系统(SCADA)等结合成现代的综合控制系统。

具体实施方式：
实施例1：
如图3所示，双工作缸1具有共同的活塞杆5并联，双缸的一端与第一差流可调梭阀3的一端和二位四通换向阀2的介质口连接，介质通过三联件从压力源进入换向阀；双缸的另一端与第二差流可调梭阀3的一端连接，第一、二差流可调梭阀的另一端相连并与二位四通换向阀的介质口连接，介质经换向阀入贮存箱。当换向阀换向时，其入口端与出口端互换与上述固定接口的元件连接。
实施例2：
如图1所示，双工作缸1具有共同的活塞杆5并联，双缸的一端与第一差流可调梭阀3的一端连接，第一差流可调梭阀3的另一端与二位四通换向阀2的介质出口连接；双缸的另一端与第二差流可调梭阀3的一端连接，第二差流可调梭阀的另一端与二位四通换向阀2的介质入口连接。
实施例3：
如图2所示，双缸1串联，其一端与梭式三通分流调节阀4的端口A连接，分流调节阀的端口B与二位四通换向阀2的介质入口端连接，分流调节阀的端口C与差流可调梭阀3的一端和二位四通换向阀2的介质出口端连接，差流可调梭阀3的另一端与双缸的另一端连接。
实施例4：
如图4所示，单缸1的一端与第一差流可调梭阀3的一端和二位四通换向阀2的介质出口端连接，单缸的另一端与第二差流可调梭阀3的一端连接，第一、第二差流可调梭阀的另一端相连并与二位四通换向阀2的介质入口端相连。上述各例中的差流可调梭阀由调节件11、梭芯12、调节件13、端口14、壳体15、梭腔16，旁通道17、端口18组成，其工作原理如下：
基本原理：基于对平衡、对称并沿着管道轴心线，悬浮在介质中线性运动的“自由梭”进行正反方向限位或附加能量，实现正反向流量的调节控制。把失衡后的差动特性放大或直接用于调节。利用介质自身的能量实现控制。
特点：元件对称、平衡，结构力学特性、流体特性合理，结构简单、节能。“自由梭”与调节件相配合，构成集敏感、控制、执行为一体、响应速度快的控制元件。调节件11、13可设为定比调节、手动或在线无级调节，实现多种功能。
实施例5：
如图5所示，单作用缸1与二位四通阀2连接，其一个回路上连接有差流可调梭阀2。
实施例6：
如图6所示，双作用缸1与三位四通阀2连接，其一个回路上有差流可调梭阀2，该梭阀通过另一差流可调梭阀与另一回路连接。
实施例7：
如图7所示，两个双作用缸并联与二通二四阀连接，四个回路上均有差流可调梭阀2。
