Description

一种适用于大口径高压偏心球阀
技术领域
本发明涉及偏心球阀技术领域，特别涉及一种适用于大口径高压偏心球阀。
背景技术
球阀作为应用较为广泛的阀门之一，具有密封可靠、结构简单、维修方便、密封面与球体常在闭合状态，不易被介质冲蚀等优点。由于超低温介质的特殊性，以LNG液化天然气为例，LNG液化天然气升温后体积膨胀600倍，将引起球阀内部压力骤升，因而超低温阀门应当具有自泄压功能，从而避免中腔压力过高发生事故。现有技术中低温球阀多采用半球阀来保证中腔泄压，从而减小阀门腔体压力升高的风险。若阀盖与阀体的偏心处理不到位时，阀盖与阀体安装不到位，阀杆在阀盖上的位置以及伸入流道内的位置均会出现偏差，影响阀芯与阀座之间的密封性能。传统的球阀定位是在下阀盖出加装卡圈，由于是在阀体内部，有可能与介质接触，故容易受介质影响，使用寿命短，易磨损。
发明内容
针对现有技术中的上述不足，本发明提供了一种适用于大口径高压偏心球阀，其具有口径大、耐高压、流量系数更大、可靠性高、调节性能更好等特点。
为了达到上述发明目的，本发明采用的技术方案为：
一种适用于大口径高压偏心球阀，包括：锻造式结构的阀体，阀体中部插设阀杆，所述阀杆下部套设半球结构的阀芯，所述阀芯位于阀体内侧，所述阀芯一侧接触阀座一侧，所述阀座另一侧通过螺钉连接压盘，所述阀体与阀杆之间的上、下端分别设有上填料衬垫、下填料衬垫，所述阀体上方通过螺栓连接上填料函，所述阀体下方通过螺栓连接底盖板，所述上填料函上方通过螺栓连接日字型支架，所述支架底端与阀杆之间设有上填料压垫，所述上填料压垫上方设有填料压板，所述填料压板与支架底端通过螺栓固定，所述阀杆上端设有轴承，所述轴承与支架中部接触连接。
进一步，所述阀芯与阀杆通过锥销连接。
进一步，所述压盘与阀座的上、下端均与阀体开口一侧的内壁接触。
进一步，所述上填料衬垫上方、下填料衬垫下方均设有填料，所述上填料衬垫上方的填料位于上填料函内侧。
进一步，所述上填料函与阀体之间、底盖板与阀体之间均设有齿型密封垫。
本发明的有益效果为：
角行程阀门的阀杆为转动式，介质不易向外泄露，而且还可以采用密封效果更好的填料，使角形成的密封性能比直行程阀提高数倍，特有的日字型支架定位系统，在外部进行定位，不与介质接触，定位更精确，更能保证使用寿命与精度。

该装置使用过程中，介质经过管道流到经压盘5和阀座6，然后到阀芯2，阀芯2、日字型支架8通过阀杆的旋转运动，对阀芯与阀座截面积的大小进行调节，从而对管道内介质的流量和压力进行调节。
以上所述仅为本发明专利的较佳实施例而已，并不用以限制本发明专利，凡在本发明专利的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明专利的保护范围之内。
