Description

全金属双向高压蝶阀
技术领域
本发明涉及全金属双向高压蝶阀，用来实现管路***通断及流量控制的部件，在石油、化工、冶金、水电等许多领域中得到广泛的应用。
背景技术
目前在已知的蝶阀技术中，其密封形式多采用密封结构密封材料为橡胶、聚四氟乙烯、多层次复合材料等。由于结构特征的限制，不适应耐高温、高压及耐腐蚀、抗磨损等行业。
工业上高温高压硬密封阀门主要以闸阀、截止阀为主，此类阀门主要缺点是：阀门都为上下开启结构，阀门本身重量大，成本高，现场安装空间大。
发明内容
针对上述缺陷，本发明的目的在于提供一种密封面之间无摩擦，具有双向密封功能，安装时不受介质流向限制且能够承受高压的全金属双向高压蝶阀。
为此本发明所采用的技术方案是：包括阀体、阀杆、碟板和驱动装置，所述阀杆上端与驱动装置连接，阀杆下端与碟板固定连接，阀体内设有活动阀座置于碟板一侧，活动阀座外侧设有吊环通过螺钉与其固定连接，碟板上设有碟板密封面，活动阀座上设有与碟板密封面密封配合的阀座密封面，碟板上固定连接有碟板压环，碟板与碟板压环之间设有活动密封环位于碟板密封面处。
所述阀体与活动阀座之间设有密封垫片一。
所述活动密封环与碟板之间设有密封垫片二。
本发明的优点是：本发明采用三偏心密封原理，密封性能好，具有双向密封功能，安装时不受介质流向的限制且能够承受高压，取代了传统的高温高压闸阀、截止阀及球阀，从而降低了生产成本，在石油、化工、冶金、水电等许多领域中得到广泛的应用。
附图说明
图1是本发明的结构示意图。
图2是图1中A的放大图。
图3是本发明的三偏心原理图。
图中1是阀体、2是阀杆、3是碟板、4是驱动装置、5是活动阀座、6是吊环、7是螺钉、8是碟板压环、9是活动密封环、10是密封垫片一、11是密封垫片二。
具体实施方式
全金属双向高压蝶阀，包括阀体1、阀杆2、碟板3和驱动装置4，所述阀杆2上端与驱动装置4连接，阀杆2下端与碟板3固定连接，阀体1内设有活动阀座5置于碟板3一侧，活动阀座5外侧设有吊环6通过螺钉7与其固定连接，碟板3上设有碟板密封面，活动阀座5上设有与碟板密封面密封配合的阀座密封面，碟板3上固定连接有碟板压环8，碟板3与碟板压环8之间设有活动密封环9位于碟板密封面处；所述阀体1与活动阀座5之间设有密封垫片一10；所述活动密封环9与碟板3之间设有密封垫片二11。
活动阀座5和活动密封环9均采用合金锻件材料经热处理后加工成形制的，能够达到相应密封所需要的硬度，无论在低温或高温的情况下，均具有较好的密封性能，采用三偏心密封结构，具有双向密封性能，安装时不受介质流向的限制，并能够承受高压。
