Abstract

一种锅炉循环管路调节阀，包括阀体，安装于阀体内部的阀芯以及与阀芯固定连接的阀杆，阀杆与阀芯配合处分为直段和外螺纹段，所述直段上设有限位台阶，限位台阶与阀芯上端的阶梯面抵接，阀芯上端面通过螺钉固定连接一压板，压板与阀芯之间通过密封环密封，所述外螺纹段与阀芯的内螺纹固定连接，所述阀杆上开有轴向孔和径向通孔，轴向孔与径向通孔相互连通。本发明有益效果是：阀芯与阀杆之间采用压板、螺钉加螺纹的连接方式，可实现快速装配与拆卸，维修极为方便；阀杆上开有的相互连通的轴向孔和径向通孔，使阀腔之间压力平衡，有效的降低了阀门操作力。

Description

一种锅炉循环管路调节阀
所属技术领域
本发明涉及流体控制领域，特别涉及一种锅炉循环管路调节阀。 
背景技术
在超（超）临界火电机组锅炉采用直流锅炉带BCP（锅炉循环泵）的循环系统中，由于BCP循环管路调节阀在小开度时需要承受大压差，现有调节阀通常采用普通笼式调节阀，阀芯阀杆采用螺纹焊接连接，当阀杆或阀芯出现损坏时，拆卸维修极不方便。 
发明内容
为了克服现有调节阀结构的上述缺点，本发明提供一种可实现快速装配和拆卸，维修方便的锅炉循环管路调节阀。 
本发明解决其技术问题所采用的技术方案是，一种锅炉循环管路调节阀，包括阀体，安装于阀体内部的阀芯以及与阀芯固定连接的阀杆，阀杆与阀芯配合处分为直段和外螺纹段，所述直段上设有限位台阶，限位台阶与阀芯上端的阶梯面抵接，阀芯上端面通过螺钉固定连接一压板，压板与阀芯之间通过密封环密封，所述外螺纹段与阀芯的内螺纹固定连接，所述阀杆上开有轴向孔和径向通孔，轴向孔与径向通孔相互连通。 
本发明的有益效果是：阀芯与阀杆之间采用压板、螺钉加螺纹的连接方式，可实现快速装配与拆卸，维修极为方便；阀杆上开有的相互连通的轴向孔和径向通孔，使阀腔之间压力平衡，有效的降低了阀门操作力。 
下面结合附图和实施例对本发明进一步说明。 
图1是实施例的构造图。 
图中：1.阀杆；2.径向通孔；3. 压板；4.限位台阶；5.螺钉；6.轴向孔；7.密封环；8.阀芯；9.阀体。 
具体实施方式
如图1所示，一种锅炉循环管路调节阀，包括阀体9，安装于阀体9内部的阀芯8以及与阀芯8固定连接的阀杆1，阀杆1与阀芯8配合处分为直段和外螺纹段，所述直段上设有限位台阶4，限位台阶4与阀芯8上端的阶梯面抵接，阀芯8上端面通过螺钉5固定连接一压板3，压板3与阀芯8之间通过密封环7密封，所述外螺纹段与阀芯的内螺纹固定连接，所述阀杆1上开有轴向孔6和径向通孔2，轴向孔6与径向通孔2连通。
