Description

一种三偏心双向硬密封碟阀
技术领域
本发明涉及阀门，具体涉及一种三偏心双向硬密封碟阀。
背景技术
碟阀作为一种用来实现管路系统通断及流量控制的部件，已在石油、化工、冶金和水电等许多领域中得到极为广泛地应用。在传统的碟阀结构中，其密封结构材料为橡胶、聚四氟乙烯等，由于材料性能的限制，不适应耐高温、高压及耐腐蚀、抗磨损等工况，既影响生产的正常运行，又增加了设备维护成本。
发明内容
针对现有碟阀的缺点，本发明提供一种新型的三偏心双向硬密封碟阀。
为了实现上述目的，本发明所采取的措施：
一种三偏心双向硬密封碟阀，包括阀体，阀体内设置与阀杆连接的碟板，碟板的回转中心与阀板密封截面及阀体中心线形成双偏置尺寸，阀杆通过设置在顶端的涡轮装置与手轮连接，阀座上堆焊耐磨金属层，碟板上设有与耐磨金属层相配合的密封圈，阀体密封面中心线与阀座中心线形成一个角偏置，在阀杆与阀体顶部密封连接处设有填料和O型圈组合的双重密封装置。
阀杆与碟板采用过膛销连接。
密封圈采用螺钉和压圈紧固连接。
密封圈材料为304不锈钢和石墨。
耐磨金属层材料选用304不锈钢。
填料为柔性石墨。
本发明的有益效果：采用双向硬密封结构，耐磨、耐高温性能好，安全可靠，使用寿命长。
