Description

硅溶胶高平台浮动球阀
技术领域
本发明涉及球阀制作领域，尤其涉及硅溶胶高平台浮动球阀。
背景技术
浮动球阀是一种阀芯能够在介质作用下运动的球阀，其阀芯在介质压力作用下，能产生一定的位移并紧压在出口端的密封面上，从而密封出口端。为了实现对于浮动球阀的控制，需要将阀杆穿过阀体上的阀杆安装孔而与阀芯联动设置，通过旋转阀杆来控制阀芯旋转以实现阀的开启和闭合。
现有技术的阀杆采用上装式，阀杆在高压下容易向上冲出导致阀体泄漏，再者现有的阀杆填料为简单的填充安装，长期使用会导致脱落，密封效果较差，有待改进。
发明内容
本发明针对现有技术的不足，提供了一种密封效果好，有效防止阀杆向上冲出，使用寿命长的硅溶胶高平台浮动球阀。
为实现本发明目的，提供了以下技术方案：硅溶胶高平台浮动球阀，包括阀体，阀体右侧与阀体密封连接的阀盖，阀体内腔设置有阀球，阀球中心开设有阀杆卡槽，阀杆末端插设于阀杆卡槽内，阀体侧壁上设置有阀杆延伸部，阀杆从阀杆延伸部上端插入，阀杆上端加工有外螺纹，阀杆上端套设有碟形弹簧，并旋接有六角螺母，其特征在于阀杆末端为截面为T字型的变径段，包括小径段和大径段，阀杆延伸部下部设置有与大径段配和的阔孔，大径段上端与阔孔接触面设置有下填料层，变径段上设置有静电放出装置，静电放出装置包括开设于变径段表面的若干个深孔，深孔内依次设置有弹簧和钢珠。
作为优选，阀杆中段设置有填料装置，填料装置包括依次套设于阀杆上的填料、耐磨片以及填料压盖。
作为优选，阀体与阀盖的连接面上设置有密封垫圈。
作为优选，阀球上设置有泄压孔，泄压孔连通阀杆卡槽和阀球内腔。
作为优选，阀体内腔中心阔设有阀球腔，阀球腔内表面为球状，阀座卡设于阀球腔两端。
本发明有益效果：阀杆采用有倒密封的下装式结构，倒密封的密封力随着介质压力的增高而增大，而且，当阀腔异常升压时，阀杆不会被冲出。采用弹簧-柱塞式静电引出装置，使球体与阀杆以及阀杆与阀体之间形成静电通道，达到消除静电积累的目的。
