由于水封式地漏具有的种种问题,所以新式的非水封式地漏也就应运而生,以下是主要的几种:
1、偏心块式:即用一个密封垫,一边用销子固定,利用重力偏心原理来密封,弊端一是封闭不严密,二是销钉容易损坏,造成失效;
2、浮球式:利用一个塑料球漂浮来封闭排水口,但一段时间内不补水,密封就会失效;
3、弹簧式:分为上弹式和下弹式。上弹式是按压盖板,盖板弹起来,再次按压,就会复位;下弹式是用弹簧拉伸密封芯下端的密封垫来密封。由于弹簧是由硼铁制成,容易锈蚀,弹性逐渐减弱,直至失效,寿命不长,另外弹簧容易缠绕毛发、织物,不易清理;
4、吸铁石式:用两片磁铁的磁力吸合密封垫来密封。由于地面水水质很差,如洗刷物品、刷地等各种原因,污中会含有一些铁质杂质吸附在吸铁石上,一段时间后,杂质层就会导致密封垫无法闭合,另外由于地球大磁场的作用,磁力也会逐渐衰弱。
