圆形模块式

YJK/Y 型圆形压紧块是一个集成式组件，与模块一起装入圆形框架中，构成圆 形模块式电缆 / 管道贯穿密封装置。通过调节正面的螺母挤压压紧块，达到压紧模 块和密封的目的。对于已铺设好的电缆与管道可以将该组件切开后安装。压紧块底 部带网罩，当压紧块垂直安装时可以防止模块掉落。 

The YJK/Y round keeper block is an integrated component and together with module to insert the  round frame, which forms the round modular cable/pipe transits. To achieve the purpose of pressing  the module and sealing it, we have to adjust the screws on the round keeper blocks. The round  keeper blocks can be cut open to serve the cable/pipe already paved. The net cover beneath the  block can work to prevent the block from slipping when it vertically is installed.
