Abstract

一种核安全级针型阀，包括阀杆，阀杆伸入阀体内，阀杆的端部设有阀瓣，阀体上设有介质进出口通道，阀杆上套装有波纹管组件，波纹管组件通过阀盖压紧，阀盖再通过压盖螺母与阀体固定连接，阀杆最上端还连接一手柄，手柄与阀盖之间通过螺纹连接，阀盖与阀杆之间设有填料，填料由上填料和下填料组成，填料通过填料压套固定密封，上、下填料之间设有填料支撑环，在与填料支撑环相配合的阀盖处开有通孔，通孔上连接一引漏管，引漏管上连接一检漏阀。本发明的有益效果：可以随时打开检漏阀，以检测下填料是否失效，当检测出下填料失效时即可进行维修更换，而此时上填料的密封性能维持有效，从而保证阀门的密封性能，杜绝安全事故的发生。

Description

一种核安全级针型阀
所属技术领域
本发明涉及一种阀门，尤其涉及一种针型阀。
背景技术
一般，针型阀在阀杆与阀盖之间会使用填料进行密封，只有当填料密封完全失效时，才能反映出介质泄漏的问题，此时再进行维修更换为时已晚，特别时当介质具有腐蚀性时，给操作者的人身健康带来危险。
发明内容
为了克服现有针型阀的上述缺点，本发明提供一种在阀门密封性能没有完全失效时，即可检测出部分填料已损坏的针型阀。
本发明解决其技术问题所采用的技术方案是，一种核安全级针型阀，包括阀杆，阀杆伸入阀体内，阀杆的端部设有阀瓣，阀体上设有介质进出口通道，阀杆上套装有波纹管组件，波纹管组件通过阀盖压紧，阀盖再通过压盖螺母与阀体固定连接，阀杆最上端还连接一手柄，手柄与阀盖之间通过螺纹连接，阀盖与阀杆之间设有填料，填料由上填料和下填料组成，填料通过填料压套固定密封，上、下填料之间设有填料支撑环，在与填料支撑环相配合的阀盖处开有通孔，通孔上连接一引漏管，引漏管上连接一检漏阀。
本发明的有益效果是：在与填料支撑环相配合的阀盖处开有通孔，并连接检漏阀的结构，可以随时打开检漏阀，以检测下填料是否失效，当检测出下填料失效时即可进行维修更换，而此时上填料的密封性能维持有效，从而保证阀门整体的密封性能，杜绝安全事故的发生。
附图说明
图1是本实用新的结构示意图。
图中：1.螺母；2.手柄；3.填料压套；4.上填料；5.填料支撑环；6.下填料；7.阀盖；8.压盖螺母；9.波纹管组件；10.阀杆；11.通孔；12.引漏管；13.检漏阀；14.阀体；15.阀瓣。
具体实施方式
如图1所示，一种核安全级针型阀，包括阀杆10，阀杆10伸入阀体14内，阀杆10的端部设有阀瓣15，阀体14上设有介质进出口通道，阀杆10上套装有波纹管组件9，波纹管组件9通过阀盖7压紧，阀盖7再通过压盖螺母8与阀体14固定连接，阀杆10最上端还连接一手柄2，手柄2与阀盖7之间通过螺纹连接，阀盖7与阀杆10之间设有填料，填料由上填料4和下填料6组成，填料通过填料压套3固定密封，上、下填料之间设有填料支撑环5，在与填料支撑环5相配合的阀盖7处开有通孔11，通孔11上连接一引漏管12，引漏管12上连接一检漏阀13。使用时，可以随时打开检漏阀13，若有介质流出，则表明阀杆处的波纹管密封以及下填料密封已经失效，需要更换维修。
