Description

电力工业用疏水球阀
技术领域
本发明属于球阀技术领域，尤其涉及一种电力工业用疏水球阀。
背景技术
球阀是启闭球体由阀杆带动，并绕球阀轴线作旋转运动的阀门，在管道中主要起截断作用，随着科学技术的飞速发展，生产工艺及产品结构的不断改进，球阀已迅速发展成为一种主要的阀类，球阀被广泛的应用在石油炼制、长输管线、化工、造纸、制药、水利、电力、市政、钢铁等行业，在国民经济中占有举足轻重的地位。但是，常规的硬密封球阀阀座活塞环密封采用柔性石墨，受材料的限制，阀门使用温度大于550℃后极易出现内漏，且当阀门公称压力大于Class2500，柔性石墨极易冲散致阀门失效，尤其是在电力工业用疏水球阀，受阀门使用温度和阀门公称压力的影响，常规硬密封球阀极易出现严重内漏，影响装置运转周期。
发明内容
本发明的目的是为了解决上述技术问题，而提供电力工业用疏水球阀，从而实现密封阀体，提高阀门有效使用性能。为了达到上述目的，本发明技术方案如下：
电力工业用疏水球阀，包括阀体、设于阀体内的流道内腔、可旋转启闭流道内腔的球体、抵持球体的两侧的上游阀座和下游阀座、以及贯穿阀体延伸至球体的阀杆，其特征在于：所述上游阀座与流道内腔的内壁之间浮动连接，所述下游阀座与流道内腔的内壁之间胀接，位于球体的上方设有嵌入阀体内的轴承，所述阀杆的底部为多边形结构，阀杆贯穿轴承延伸嵌入至球体顶部，阀杆与轴承之间可拆卸锁紧固定连接。
具体的，所述上游阀座的一端抵接球体，上游阀座的另一端抵接嵌入流道内腔的内壁的第一弹性件。
具体的，所述上游阀座与第一弹性件之间夹持设有第二弹性件。
具体的，所述阀杆与阀体之间填充设有填料，阀体的顶端设有套接阀杆封堵填料的压板，压板的顶部设有套接阀杆的压盖。
具体的，所述阀杆的上部套设有架置于阀体上的支架，支架内穿设有锁紧至阀体的安装件。
具体的，所述支架的顶部设有套接阀杆的顶端的连接套，连接套的外周套设有手柄，连接套与阀杆之间可拆卸锁紧固定连接。
具体的，所述阀杆的底部为正方体结构，所述球体顶部开设有与正方体结构相对应匹配的凹槽。
具体的，所述阀杆与轴承之间通过锁紧销连接固定。
与现有技术相比，本发明电力工业用疏水球阀的有益效果主要体现在：
阀体采用一体式结构，有效提高阀门的使用性能；下游阀座与阀体采用胀接的连接方式，且采用相同的材质，有效避免因热胀冷缩引起的泄漏问题，尤其对于电力工业应用，温度交叉变化大，密封效果显著；阀杆与球体的连接采用多边形结构插接的方式，有效防止球体发生过大位置偏移，确保阀门的可靠密封；轴承与阀杆之间可拆卸锁紧固定连接，保证阀杆旋转作业中防止飞出脱离阀体，提高阀杆的强度；通过连接套安装手柄，起到稳定固定作用，有效减少阀杆安装的零部件。
