Description

快开换向阀体
技术领域：
本发明涉及阀门的部件，尤其涉及一种快开换向阀体。
背景技术：
阀门是流体输送系统中的控制部件，包括球阀、截止阀、闸阀和换向阀等。其中，换向阀是一种具有两种以上流动形式和两个以上流口的方向控制阀，它具有多向可调的通道，且可适时改变流体的流向。然而在现有的换向阀工作中，需要通过对手轮的转动来控制阀瓣，进而改变流体的流向，非常消耗体力。鉴于此，本发明通过对其阀瓣和阀体的改造，提供一种快开换向阀体，安装在截止阀内进行工作与运行。
发明内容：
本发明提供一种快开换向阀体，位于截止阀内腔，所述的快开换向阀体由换向阀体和手柄组成，在换向阀体的左右两边分别设有三个通孔；在换向阀体的左边从上到下分别设有储缸进流孔、储缸进出流孔和高压进流孔，在换向阀体的右边从上到下分别设有排出低压管路、下缸流体进出孔和上缸进出流孔；在换向阀体的顶端连有可左右摇摆的手柄；在换向阀体的底端设有阀瓣，阀瓣与截止阀内的活塞相连，手柄通过控制阀瓣从而带动活塞上下移动，控制整个截止阀的开启和关闭。
作为本发明的进一步改进：所述的换向阀体背后(阀体的前内壁壳体中)由外向内斜向打一个通孔，通孔内设有不锈钢板过滤网，此通孔的外口是过滤器进出口通道，也是过滤后的清洁水出口；通孔为螺纹连接，拆卸方便，更换容易。
附图说明：
图1为本发明的截止阀剖面图；
图2为本发明的剖视图；
图3为本发明的关闭剖面图；
图4为本发明的打开剖面图；
图5为本发明的成型车刀主视图；
其中，1-阀瓣，2-活塞，3-手柄，4-储缸进流孔，5-高压进流孔，6-储缸进出流孔，7-排出低压管路，8-下缸流体进出孔，9-上缸进出流孔，10-上缸进出流体孔，11下缸进出流体孔。
具体实施方式：
本发明用于阀门开关，通过一进四出，一个进流孔，两个换向出流孔，流进储缸，再由储缸流进低压管内，使阀门的活塞2换向，达到阀门开关的目的。本发明的两头流体通径大小一致，中间底部底部作为一个缸体，直径为两头通径的1.2倍，由换向阀体通过把左边进流流体进行换向供给，通过活塞2来指挥阀瓣开关，由于活塞2的面积略大于阀瓣1，所以阀瓣1开关自如。
本发明的快开换向阀体，当流体从上缸进出流体孔10进入缸体，导致活塞2向下运动，活塞2与阀瓣1相连，阀瓣1随着活塞2一起向下运动，阀门被打开；当把手柄向左偏移15°时，缸体内的流体从下缸进出流体孔11流出，活塞2和阀瓣1回到原始状态，阀门被关闭。结合图3，其具体流程为：当高压进流孔5进入高压流体时，直接通过上缸进出流体孔10进入下缸，关闭储缸进出流孔6，同时关闭排出低压管路7，使储缸内的流体进入储缸进流孔4，通过下缸流体进出孔8排出，形成阀门关闭；结合图4，其具体流程为：当高压流体进入高压进流孔5时，流体换向，通过下缸流体进出孔8进入上缸，使活塞2下行.使得阀门打开。同时打开上缸进出流孔9，使流体进入储缸进出流孔6，流体从储缸进流孔4排出到低压缸，使阀门打开。
本发明的快开换向阀体的扭矩非常小，只需要使用10N以内的力即可轻松控制手柄3，即使是年幼的孩童也可对本发明进行开关控制，非常省力。
另外，本换向阀的控制部件加工十分简单，只需要用一个专用成型车刀(图5所示)一刀车槽、倒圆角、车两个斜面一次完成。
