Abstract

本实用新型涉及一种封闭式下水管封闭节。采用的技术方案是:下水管一端插入外壳内,下水管和外壳通过法兰盘固定并封闭,下水管插入外壳内的端部设有活舌,活舌通过连接件与下水管活动连接。本实用新型由于设有活舌,脏水通过下水管时,将活舌打开,流走,当下水管内没有脏水时,活舌靠重力自然回落,将下水管的端口封闭,这样既防止了异味的上返,当下水主管道堵塞时,污物及脏水不会反流,因此可保持室内空气清新。

Description

封闭式下水管封闭节
技术领域
本实用新型涉及一种主要应用于下水管处防止异味及污物上返的装置。 
背景技术
在卫生间及厨房的下水管处,由于下水管直接连通下水主管道,因此经常有异味通过下水管上返至室内,造成室内空气污染。另外当下水主管道堵塞时,污物及脏水也会通过下水管返流入室内,给用户造成很大损失。 
发明内容
为了解决以上问题,本实用新型提供一种可以防止异味、污物及脏水上返的封闭式下水管封闭节。 
本实用新型为了实现上述目的,采用的技术方案是:一种封闭式下水管封闭节,其特征在于:下水管一端插入外壳内,下水管和外壳通过法兰盘固定并封闭,下水管插入外壳内的端部设有活舌,活舌通过连接件与下水管活动连接。 
本实用新型的有益效果是:由于设有活舌,脏水通过下水管时,将活舌打开,流走,当下水管内没有脏水时,活舌靠重力自然回落,将下水管的端口封闭,这样既防止了异味的上返,当下水主管道堵塞时,污物及脏水不会反流,因此可保持室内空气清新。 
附图说明
图1是本实用新型的结构示意图。 
图2是外壳的结构示意图。 
图3是下水管的结构示意图。 
具体实施方式
如图1~图3所示,封闭式下水管封闭节:下水管(2)一端插入外壳(1)内,外壳(1)和下水管(2)通过法兰盘(5)固定并封闭,下水管(2)插入外壳(1)内的端部设有活舌(3),活舌(3)通过连接件(4)与下水管(2)活动连接。 
使用时,将下水管(2)与厨房或卫生间的下水管连接,外壳(1)与下水管主管道连接。
