Description

外螺纹截止阀
技术领域
本实用新型涉及阀门,尤其涉及一种截止阀。
背景技术
传统的截止阀具有流量小、压力大等特点,因而广泛应用于电站、石油、化工等行业。但是,由于阀杆与阀瓣采用分体式结构,在长时间的高压状态下反复作用后,经常出现阀瓣松脱、变形等现象,从而导致密封不严,易发生生产事故。
实用新型内容
针对现有的截止阀的缺点,本实用新型提供一种新型的外螺纹截止阀。
为了实现上述目的,本实用新型所采取的措施:
外螺纹截止阀,包括阀体和阀盖,阀体内设有与其锻造成一体的阀座,阀体内还设有与阀瓣成一体的阀杆,阀杆通过其外螺纹与阀盖的内螺纹连接,阀盖外侧设有锁紧螺母,阀杆外端设有手轮。
在阀盖与锁紧螺母之间由内向外依次设有填料垫、填料和填料压盖。
本实用新型的有益效果:安装、拆卸方便,连接紧固,密封性能好,安全可靠。
附图说明
图1本实用新型的结构示意图。
具体实施方式
外螺纹截止阀,包括阀体4和阀盖6,阀体4内设有与其锻造成一体的阀座,阀座耐磨性能大大提高,阀体4内还设有与阀瓣成一体的阀杆11,提高了阀瓣的刚度和强度,实现了阀瓣与阀座的良好密封。阀杆11通过其外螺纹与阀盖6的内螺纹连接,阀盖6外侧设有锁紧螺母10,阀杆11外端设有手轮12,操作方便、连接紧固。在阀盖6与锁紧螺母10之间由内向外依次设有填料垫7、填料8和填料压盖9,密封性好。本实用新型的有益效果:安装、拆卸方便,连接紧固,密封性能好,安全可靠。
本领域内普通的技术人员的简单修改和替换都是本实用新型的保护范围之内。
