空气的过滤是气动控制中的重要环节。一般在使用中要求每台装置的供气都要装分水过滤器,用来进一步去除空气中的水份和杂质。目前,国内使用的分水过滤器大多要人工排水。我厂试制成一种带有自动排水机构的新型分水过滤器。这种过滤器适用于某些难于接近的操作环境,或要求能远距离控制放水的场合。结构原理分水过滤器的自动放水机构是装在分水过滤器的放水杯中的,结构如图所示。图示位置为无气状态,浮筒3压在支承架5上,阀口~a打开。当气源压力超过一定值时,即B腔压力大于A腔压力,气压把活塞8向上推,关闭阀口a。在放水杯1里
Air filtration is an important part of pneumatic control. Generally require the use of each device’s gas supply must be equipped with water filters, to further remove air moisture and impurities. At present, most of the domestic use of water filters to artificial drainage. I plant trial made a new automatic water diversion agencies with water filters. This filter is suitable for some difficult to access operating environment, or require long-distance control of the water discharge occasions. Structural principle Water diversion filter automatic water release mechanism is installed in the water diversion cup filter, the structure shown in the figure. The figure shows an airless state, the buoy 3 presses on the support frame 5, and the valve port a is opened. When the air supply pressure exceeds a certain value, that is, the pressure in chamber B is greater than the pressure in chamber A, and the air pressure pushes the piston 8 upward to close valve port a.
