Abstract

密封垫,是一种管网堵漏装置,它克服了目前技术的不足,它是由橡塑类托瓦层、骨架受力层、橡塑类密封层、网格楞为一体的,其外层为橡塑类托瓦层,中间为骨架受力层,里层为橡塑类密封层;密封层上面四周为楞,其中间为各个独立封闭的网格楞;受力层为受力骨架;此装置适用于管网堵漏方面。

Description

密封垫
一、本实用新型涉及一种管网堵漏装置,尤其是密封垫。
二、背景技术:随着管道泄漏的增多,堵漏方式也多样化,密封材料也层出不穷。目前,国内大多数密封垫虽然能起到一定的密封作用,能达到一定的堵漏目的。但是,它们在使用上都不同程度地存在着不耐寒、不耐热、承载压力低、依附钢制托瓦的问题。因此,应用范围小,使用寿命短。
三、发明内容:本实用新型的目的是提供密封垫,它克服了目前技术的不足,本实用新型的目的是这样实现的,它是由橡塑类托瓦层、骨架受力层、橡塑类密封层、网格楞为一体的,其中:橡塑类托瓦层为外层,骨架受力层为中间层,橡塑类密封层为里层;密封层上四周为楞,其中间为各个独立封闭的网格楞;受力层为骨架。
工作原理:使用时,将橡塑类密封层对准管网泄漏点,用钢带将橡塑类托瓦层直接兜住,然后用钢带拉紧器将钢带拉紧,并锁紧钢带,从而达到堵漏的目的。密封垫托瓦层采用橡塑类材料制作,增加了托瓦的适应性,扩大了密封垫的应用范围(各种直径的直管和弯管),同时取消了钢制托瓦的不适应性和制造费用;骨架受力层采用受力材料制作,增加了密封垫的受力程度;密封垫的密封层采用不同橡塑类材料制作,可达到耐油,耐热、耐寒、耐磨、耐酸碱的目的。
四、附图说明:图1为主视图,其中1、网格楞。
图2为密封垫的俯视图,图中:2、橡塑类托瓦层  3、骨架受力层  4、橡塑类密封层。
五、具体实施方式:在图1和2中,密封垫外层为橡塑类托瓦层2,中间为骨架受力层3,里层为橡塑类密封层4;橡塑类密封层上面为四周楞1其中间为各个独立封闭的网格楞1;受力层为受力骨架。

Claims (3)
