Abstract

目前塑料管件及圆形塑料容器的接口连接密封，均采用胶体物质粘接或将接口用铁件连接，连接后经常出现密封不严，漏气或漏水，本发明实现了塑料管件及圆形塑料容器在连接的同时，也解决了密封问题。通过在接口的一端螺母内设置了一个锥形密封环，在与另一接口螺杆连接时，由于内、外螺纹的旋进，将锥形密封环挤压入另一管口内，锥形密封环靠张力作用将两个连接件紧密贴紧，从而实现了塑料管件之间的密封连接，因塑料密封环不易老化，所以密封时间长久，密封效果可靠。

Description

塑料螺母内锥形密封环
技术领域
本发明解决了圆形、管形塑料件之间的连接密封问题。该发明实现塑料水管、塑料通气管线及塑料容器的连接结合处密封。有非常好的应用前景。
背景技术
目前塑料管件及圆形塑料容器的接口连接密封，均采用胶体物质粘接或将接口用铁件连接，连接后经常出现密封不严，漏气或漏水，而且费时费工浪费材料。有时塑料管件及圆形塑料容器的接口连接密封时，还采用橡胶垫是密封，由于橡胶垫易老化，密封效果也不理想。本发明实现了塑料管件及圆形塑料容器在连接的同时，也解决了密封问题。
发明的内容
本发明实现了管形塑料件及圆形塑料容器接口的密封，通过在接口的一端螺母内设置了一个锥形密封环，在与另一接口连接时，由于内、外螺纹的旋进，将锥形密封环挤压入另一管口内，锥状密封环靠张力作用将两个连接件紧密贴紧，从而实现了塑料管件之间的密封连接。因塑料密封环不易老化，所以密封时间长久，密封效果可靠。
附图说明
图1是锥形密封环在两个塑料管连接时的密封作用原理图。
图2是锥形密封环设置在螺母内侧位置图。
图中，1、塑料管  2、锥形密封环  3、螺母接头  4、外螺纹接头  5、塑料管
具体实施方式
两个塑料管件以螺母螺杆形式连接时，旋转塑料管1，使外螺纹接头4进入螺母接头3内，在继续旋进中锥形密封环2被挤压入塑料管5口内，当螺母接头3拧紧后，锥形密封环2全部挤压入塑料管5口内，锥形密封环2在张力作用下，与塑料管5内口内壁紧密贴紧，从而实现了塑料管1和塑料管5的密封连接。
