Abstract

本实用新型提供一种建筑铝塑管管接头密封连接件,它包括管件、铝质密封套、螺母、密封圈,管件管头部外侧是螺纹,内侧为锥形面形成的空隙环。铝质密封套外侧也有同样角度的锥形面,纵向有切口,密封圈置于空隙环中,铝质密封套推入后旋紧螺母使其压紧密封圈,上述锥形面为5°—7°,保证了连接件的强度和使用寿命。

Description

建筑铝塑管管头密封连接件
本实用新型涉及一种建筑铝塑管管头密封连接件,属于管件连接技术领域。
铝塑管由于不锈化,具有广阔的发展前景。但是,密封连接件的质量一直存在密封效果差、强度低,易损坏等问题。
本实用新型的目的是在不改变管件壁厚的情况下提高密封效果,增加连接件强度。
本实用新型的技术方案是:这种建筑铝塑管管头密封连接件,主要包括管件2、铝质密封套4、螺母3和密封圈5,其管件2管头部外侧有螺纹2-1,内侧为锥形面,即内侧是纵向截面为楔形的空隙环2-2。铝质密封套4外侧为同样的锥形面,与管件上的空隙环2-2相配合,密封圈5置于空隙环2-2中,铝质密封套4推入空隙环2-2中,螺母3与管头外侧螺纹2-1配合旋紧时,铝质密封套4压紧密封圈5。实现密封连接。
上述的管头密封连接件中,其管头内侧锥形面的角度是5°-7°。
上述的管头密封连接件中,其密封圈5是硅橡胶密封圈,其截面直径大于空隙环2-2底部径向宽度,小于空隙环管头部径向宽度。
上述管头密封连接件中的铝质密封套4上有纵向切口4-1起自动调节作用。
本实用新型的优点是密封效果好,并增加了管接头强度,提高了使用寿命和反复使用率。
下面对附图进行说明:图1是本实用新型纵向截面结构示意图、图2是铝质密封套横截面示意图。图中1是管材、2是管件、3是螺母、4是铝质密封套,5是密封圈、2-1是管件2管头部外侧螺纹、2-2是管件2管头部内侧锥形空隙环、4-1是铝质密封套4上的纵向切口。
图3是连接件管头部分纵向放大剖示图:-2是管件、2-1是螺纹、α是锥形面的角度、4是铝质密封,A、B、C、D是该处尺寸标号。
下面结合附图结合附图以DN15-DN50为例说明本实用新型的实施例:下表给出了各种型号各主要部位的参数:
