Description

一种上装式高温硬密封球阀
技术领域
本发明涉及一种上装式高温硬密封球阀，属于小口径球阀技术领域。
背景技术
球阀在石油、化工、冶金和城市集中供热等行业得到了广泛的应用。高温硬密封球阀，由于零部件多，结构复杂，增加了加工难度与制造成本， 尤其是小口径的硬密封球阀。
目前，常规的侧装式球阀在管线上发生故障需要维修时，不得不把阀门从管线上拆下，但上装式球阀只要把阀盖及阀杆组合件从阀门上拆卸，即可更换密封件及球体，不会造成生产的停滞，以至于造成重大经济损失。
发明内容
目的：为了克服现有技术中存在的不足，本发明提供一种上装式高温硬密封球阀。
技术方案：为解决上述技术问题，本发明采用的技术方案为：
一种上装式高温硬密封球阀，包括：阀体、球体、压圈、销、键、左阀座、右阀座、支撑圈、阀座圈、蝶形弹簧，所述阀体通道右端设置有右阀座，右阀座左端设置有压圈，所述压圈设置为C型结构，压圈开口位置与右阀座外侧移动连接，压圈内设置有左阀座，左阀座与压圈之间设置有蝶形弹簧；所述左阀座与右阀座之间设置有球体；所述压圈左端外侧套接有阀座圈，阀座圈左端设置有支撑圈，所述阀座圈与支撑圈之间设置有蝶形弹簧，所述支撑圈左端卡接在阀体通道左端；所述压圈与阀座圈之间设置有空隙，所述空隙处设置有销，所述销上设置有与空隙相配合的键，键一端用于支撑阀座圈，键另一端用于推动压圈；所述键设置为条形结构。
作为优选方案，所述销设置为内六角圆柱头销，用于方便拆装。
作为优选方案，还包括压套、金属密封垫，所述压套、金属密封垫套接在右阀座外侧，用于保证阀体常温密封及在失火下的密封。
有益效果：本发明提供的一种上装式高温硬密封球阀，实现浮动的上装式结构，阀门结构简单、可在线维修, 减少停车经济损失。
附图说明
图1为本发明的结构示意图。
具体实施方式
下面结合附图对本发明作更进一步的说明。
如图1所示，一种上装式高温硬密封球阀，包括：阀体1、球体2、压圈3、销4、键5、左阀座6、右阀座7、支撑圈8、阀座圈9、蝶形弹簧10，所述阀体1通道右端设置有右阀座7，右阀座7左端设置有压圈3，所述压圈3设置为C型结构，压圈3开口位置与右阀座7外侧移动连接，压圈3内设置有左阀座6，左阀座6与压圈3之间设置有蝶形弹簧10；所述左阀座6与右阀座7之间设置有球体2；所述压圈3左端外侧套接有阀座圈9，阀座圈9左端设置有支撑圈8，所述阀座圈9与支撑圈8之间设置有蝶形弹簧10，所述支撑圈8左端卡接在阀体1通道左端；所述压圈3与阀座圈9之间设置有空隙，所述空隙处设置有销4，所述销4上设置有与空隙相配合的键5，键5一端用于支撑阀座圈9，键5另一端用于推动压圈3；所述键5设置为条形结构。
作为优选方案，所述销4设置为内六角圆柱头销，用于方便拆装。
作为优选方案，还包括压套11、金属密封垫12，所述压套11、金属密封垫12套接在右阀座7外侧，用于保证阀体常温密封及在失火下的密封。
具体使用方式如下：使用时，将内六角圆柱头销安装在阀体中轴线对称两侧，转动内六角圆柱销，让键卡接于压圈与阀座圈之间空隙处，由于支撑圈上蝶形弹簧的弹力使阀座圈对压圈产生了夹紧力；同时，键推动压圈向右移动，压圈带动内部球体与右阀座接触实现密封。
装配时，先从阀体顶部把右阀座、压套、金属密封垫、支撑圈、蝶形弹簧装进阀体阀座孔内；然后把压圈、左阀座、蝶形弹簧、球体与阀座圈旋合贴边再从顶部装进阀体内；再用两个内六角圆柱头销上的键，使阀座圈与压圈夹紧。此时球体与右阀座紧紧贴合，提供阀座初始密封；在拆卸时则逆序操作。
以上所述仅是本发明的优选实施方式，应当指出：对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
