Description

截止阀的阀座结构
技术领域
本实用新型涉及阀座为热塑性树脂和金属嵌件注塑结合的截止阀，尤其涉及该截止阀的阀座。
技术背景
由图1A-1E可见：现有技术中阀座由热塑性树脂阀体11和金属嵌件12经注塑而成，热塑性树脂包覆在金属嵌件外层，金属嵌件口部与热塑性树脂外层相平，阀座通过金属嵌件口部的内螺纹与阀芯的外螺纹相连接。图中：密封圈10。
由于金属嵌件与热塑性树脂的粘合强度低，金属嵌件与热塑性树脂结合处的承压强度一般低于1.6Mpa，当承压强度提高时，管路中的水或其它液体介质就会从金属嵌件与热塑性树脂
Figure Y20092006668900031
结合处的缝口溢出，影响了管道的使用安全。为提高连接后管路的质量，有必要对截止阀的构造进行设计。
发明内容
本实用新型需要解决的技术问题是提供了一种截止阀的阀座结构，旨在解决上述的问题。
为了解决上述技术问题，本实用新型是通过以下技术方案实现的：
本实用新型包括：热塑性树脂阀体和金属嵌件；在阀座金属嵌件口部的外面加覆一层热塑性树脂；所述的热塑性树脂的一端与热塑性树脂阀体连为一体，另一端与金属嵌件的内螺纹沿面相平。
与现有技术相比，本实用新型的有益效果是：提高了耐压强度，保证了连接后管路的质量。
附图说明
图1A是现有技术中截止阀组合结构图；
图1B是图1A中截止阀阀座结构图；
图1C是图1A中截止阀阀芯结构图；
图1D是图1B的俯视图；
图1E是图1B的剖面图；
图2A是本实用新型结构图；
图2B是图2A中A-A剖面图。
具体实施方式
下面结合附图与具体实施方式对本实用新型作进一步详细描述：
由图2A、图2B可见：本实用新型包括：热塑性树脂阀体11和金属嵌件12；在阀座金属嵌件12口部的外面加覆一层热塑性树脂13；所述的热塑性树脂13的一端与热塑性树脂阀体11连为一体，另一端与金属嵌件12的内螺纹沿面相平；
所述热塑性树脂13的厚度为0.5～10mm。
本实用新型中加覆热塑层增加了与金属嵌件的接触面积，提高了截止阀的耐压强度；另外，加覆热塑层改变了金属嵌件与热塑性树脂缝口之间的压力传递路径，加覆热塑层在阀芯密封圈的紧压下，提高了耐压强度，保证了连接后管路的质量。
