Description

一种分体式保温球阀
技术领域
本发明涉及阀门领域，具体是一种分体式保温球阀。
背景技术
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。球阀中设有球体，主要通过旋转球体来实现开启或者关闭介质通路的功能，再能起到切断、分配和改变介质流动方向的作用。
当球阀运用于高粘度的化工介质中时，温度降低则会造成介质发生冷凝，在球体表面和阀座密封面上产生结晶，结晶吸附在球体上会造成球体启闭困难，磨损加速，严重影响球阀的使用寿命。
发明内容
本发明提供了一种分体式保温球阀，旨在为球阀提供保温功能，以解决上述问题。
为实现上述目的，本发明的技术方案如下：
一种分体式保温球阀，包括阀杆、球体、阀座，其特征在于：阀体分为一级阀体与二级阀体，球体设置在一级阀体内；所述阀座设置在球体与一级阀体之间，与球体贴紧密贴合形成密封面；所述一级阀体内还设有中空加热套环，加热套环一端抵在阀座上，另一端超出一级阀体，并设有径向凸台；所述凸台轴向上设有通孔，径向上开有连接到加热环套内的通道；所述加热环套内缠绕有加热电阻丝。
进一步地，所述一级阀体和二级阀体均开有与凸台上通孔适配的螺栓孔，一级阀体、二级阀体与加热环套通过螺栓固定。
进一步地，所述二级阀体与凸台接触面轴向上开有放置密封圈的凹槽。
进一步地，所述密封圈为聚四氟乙烯材质的密封平垫。
本发明的有益效果在于：分体式的阀体，便于生产加工和组装。一级阀体、二级阀体与加热环套通过螺栓固定，在返修时，也利于拆卸检查。若加热环套损坏，对加热环套进行更换也很方便，能使球阀继续工作。采用电阻丝加热，电阻丝加热相比较蒸汽或热水加热，所需的材料与零件少，构成简单，容易实现，并且电阻丝加热方式，加热速度快，效率高。
附图说明
图1是本发明提供的
图中标记：1为二级阀体、2为螺栓、3为电阻丝、4为加热环套、5为一级阀体、6为密封平垫、7为阀座、8为球体、9为阀杆、10为凸台。
具体实施方式
下面结合附图与具体实施例对本发明做进一步说明。
如图1所示，一种分体式保温球阀，包括阀杆9、球体8、阀座7，阀体分为一级阀体5与二级阀体1，球体8设置在一级阀体5内；所述阀座7设置在球体8与一级阀体5之间，与球体8贴紧密贴合形成密封面；所述一级阀体5内还设有中空加热套环4，加热套环4一端抵在阀座7上，另一端超出一级阀体5，并设有径向凸台10；所述凸台10轴向上设有通孔，径向上开有连接到加热环套4内的通道；所述加热环套5内缠绕有加热电阻丝3。所述一级阀体5和二级阀体1均开有与凸台10上通孔适配的螺栓孔，一级阀体5、二级阀体1与加热环套4通过螺栓2固定；所述二级阀体1与凸台10接触面轴向上开有放置密封圈的凹槽。所述密封圈为聚四氟乙烯材质的密封平垫6。
在安装时，从凸台10上的一个通道向加热环套4穿入电阻丝3，电阻丝3缠成数股，盘绕在加热环套5内，再从凸台10的另一个通道穿出。再将加热环套4安装进一级阀体5内，加热环套4的一端抵在阀座上，再安装二级阀体1，用螺栓2将二级阀体1、二级阀体5和加热环套4相对固定。采用本发明结构简单，容易实现，有效解决球阀的保温问题。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
