Description

直启多密封角式截止阀
技术领域
本发明涉及角式截止阀，特别是一种直启多密封角式截止阀。
背景技术
传统的角式截止阀，由阀体、阀盖、插嵌并螺纹连接于阀盖内的阀杆、连接在阀杆上部的手轮、连接在阀杆下部的阀瓣、设于阀盖上部的压帽以及设于压帽、阀体、阀杆形成的填料仓内的填料组成，其中，阀体、阀盖均为铸件，需要单独加工，且内部结构复杂、加工繁琐、体积大、质量重，受铸件自身缺陷影响，整个阀门强度不高。由于阀门体积大及重量过重，其占用安装空间过大，安装和维修时工作人员劳动强度过高，安装与拆卸都不方便。
发明内容
本发明的目的是为了提供一种体积小、重量轻、开启灵活、密封性能好、易于安装、生产成本低的直启多密封角式截止阀。
本发明的技术方案是：
一种直启多密封角式截止阀，包括阀体、手轮、插嵌于阀体内的阀杆、阀瓣，所述阀杆顶部连接有蜗杆，所述手轮安装于所述蜗杆顶端，其特殊之处是：所述蜗杆上设有蜗杆螺母，所述蜗杆螺母外周面螺纹连接蜗杆螺母压板并利用螺钉锁紧，所述蜗杆螺母压板与阀体之间连接有螺纹支柱并利用螺母锁紧，所述阀体上部与阀杆形成的填料仓内设有填料并对应填料位置由下至上依次设有填料压盖及压板，所述压板利用双头螺栓和螺母与所述阀体固定，所述阀瓣与阀杆为一体式结构，所述阀体底部内置有密封座，所述密封座顶部与阀瓣对合形成锥密封且所述密封座与阀体的径向接触面设有两个间隔分布的“O”型密封圈。
所述阀瓣底面为球面，以减少阀门开启时介质对阀杆的径向冲击力，增强副密封的密封性能。
所述蜗杆与阀杆的连接端为球铰状接触，且利用两瓣式连接内套和锁紧外套连接，以使蜗杆与阀杆在阀门关闭和开启时实现自动调心。
所述密封座与阀体采用螺纹连接，并利用紧定螺钉定位固定。
所述阀体外形为立方体状结构，以使体身壁厚均匀，整体耐压度高。
所述阀体侧面和底面分别设有螺纹孔，以使阀体介质通道端面代替法兰，阀体与管道间的连接只需要有管道端法兰就可安装，从而提高了材料利用率，降低了生产成本。
所述螺纹支柱的数量为两个，以蜗杆和阀杆的轴心线为对称中心分布。
本发明的有益效果是：
1、由于蜗杆和阀杆由蜗杆螺母压板和螺纹支柱实现与阀体固定连接，同理，填料压盖及压板由双头螺栓实现与阀体的固定连接，取代了传统的内部结构复杂的铸件阀盖，节省了单独铸造阀盖的工序，减小了阀门整体重量和体积，节约了安装时间，拆卸方便，减轻了工人劳动强度，同时使填料更容易更换，易于检修。
2、由于阀瓣与阀杆为一体式结构，且阀瓣与阀座的密封为母体密封，节省了阀杆与阀瓣分开加工的繁琐工序，节省了密封面再次堆焊的工时和材料的消耗。
3、由于阀体底部内置有密封座与阀瓣形成锥密封，且密封座与阀体的径向接触面设有两个 “O”型密封圈，加大密封度达3倍以上，显著增强了阀门密封性能，达到了多密封的目的。
