Description

一种无填料密封阀
本实用新型涉及一种阀,尤其是一种无填料封阀。
阀在市场上的种类繁多,目前大多数阀对传统结构进行了改进,减少部件之间的磨损来改善密封程度,但其内部结构复杂,密封不理想,加工难度大,成本高,特别是内部零件磨损后,就要整个阀拆下来换配件甚至报废,这给用户带来很多麻烦,还造成浪费。
本实用新型的目的是提供一种密封程度高、结构简单的方便维修的无填料密封阀。
本实用新型是通过下列技术方案来解决的:它主要包括阀体、带阀门的阀杆、密封皮碗,与阀门配合的密封垫、手轮、进水口、出水口,其结构特点是处在阀体空腔内的阀杆上部设有螺纹,该螺纹与设在手轮内部的内螺纹相配合,阀杆上设有圆槽,与由压套固定在阀体上的密封皮碗相配合,手轮下沿设有并帽,与压套下沿配合。
下面结合附图对本实用新型作进一步描述。
图1为本实用新型实施例结构示意图。
如图所示,该实施例包括阀体1、带阀门2的阀杆3、密封皮碗4、密封垫7、手轮6、进水口8、出水口9,其结构特点是处在阀体1空腔内的阀杆3上部设有螺纹。该螺纹与设在手轮6内部的内螺纹相配合,阀杆3上设有圆槽,与由压套5固定在阀体1上的皮碗4相配合,手轮6下沿嵌上并帽10与压套5下端配合。
在使用中,要关闭,顺时针旋动手轮6,由于阀杆上螺纹与手轮6内的内螺纹配合,使阀杆3下移,直至关闭;要打开,反时针旋转手轮6,阀杆3上移,使水从进水口8流进,从出水口9流出。在旋动手轮6过程中,由于手轮6下沿嵌上了并帽10,与压套5下沿配合,使的手轮6不会上下移位。另外还采用了闭合密封方式,密封面不受磨损。
从上述可知,本实用新型具有结构简单,密封性好,维修方便等特点。
