Abstract

一种防静电蝶阀，涉及蝶阀。提供可有效防静电的一种防静电蝶阀。包括阀体、阀杆和蝶板；阀杆与阀体之间设有静电导出装置，静电导出装置设有导电杆和回位弹簧，阀杆上设有弹簧嵌槽，回位弹簧置于弹簧嵌槽中，导电杆一端抵压住回位弹簧，导电杆另一端与阀体触接。由于设有静电导出装置，当阀杆转动时，阀杆会将蝶板上聚集的电荷传导至阀体上，阀体会将电荷通过外接的法兰盘导出，并最终接地。因此，静电导出装置可有效防静电，显著提高蝶阀的安全性。

Description

一种防静电蝶阀
技术领域
本实用新型涉及蝶阀，尤其是涉及一种防静电蝶阀。
背景技术
由于蝶阀的阀座与蝶板之间构成密封副，密封副包含有非金属的密封，如果没有防静电装置，则静电很容易在蝶板上累积，而蝶板与阀杆连接，因此当阀杆转动时，易产生放电现象，如果该静电不能及时导出,就可能将易燃易爆的输送介质引燃引爆，导致事故发生。
如何消除静电，防止事故发生，成为业内十分关注的问题，但现有蝶阀仍然没有专门的防静电装置。
发明内容
本实用新型的目的是提供可有效防静电的一种防静电蝶阀。
本实用新型包括阀体、阀杆和蝶板；阀杆与阀体之间设有静电导出装置，静电导出装置设有导电杆和回位弹簧，阀杆上设有弹簧嵌槽，回位弹簧置于弹簧嵌槽中，导电杆一端抵压住回位弹簧，导电杆另一端与阀体触接。
由于本实用新型设有静电导出装置，当阀杆转动时，阀杆会将蝶板上聚集的电荷传导至阀体上，阀体会将电荷通过外接的法兰盘导出，并最终接地。因此，静电导出装置可有效防静电，显著提高蝶阀的安全性。
附图说明
图1为本实用新型实施例的结构示意图。
具体实施方式
参见图1，本实用新型实施例包括阀体1、阀杆2和蝶板（图1未画出）；其特点在于，阀杆2与阀体1之间设有静电导出装置，静电导出装置设有导电杆3和回位弹簧4，阀杆1上设有弹簧嵌槽11，回位弹簧4置于弹簧嵌槽11中，导电杆3一端抵压住回位弹簧4，导电杆3另一端与阀体1触接。
