Abstract

一种简易防盗闸阀，它是由阀盖、阀杆、阀杆螺母、阀板、阀座、阀体等有序构成，其中将手轮直接与阀杆通过平键连接，阀杆通过梯形螺纹与阀杆螺母连接，阀杆螺母由紧定螺钉固定在阀盖内侧，压盖通过反扣螺母固定在阀盖下部，并有内外两个“O”型密封圈起密封作用，通过底部“凹”形的圆柱体带动阀板轴向移动，实现闸阀的开启和关闭。

Description

简易防盗闸阀
所属技术领域：
本实用新型涉石油开采中的阀门，特别是一种防盗闸阀。 
背景技术：
闸阀是油气田开发不可缺少的设备。目前公知的闸阀是由阀盖、阀体、阀杆、阀座、阀板等有序组成，阀门在工作时，通过旋转手轮带动阀杆螺母旋转，从而使阀杆上下运行，带动阀板上下移动，从而达到阀门的开启和关闭。但阀杆螺母长时间暴露在外面，很容易被不法分子拆下当废铜出售，严重影响了油气田的正常生产，甚至造成重大事故。 
发明内容：
为了克服闸阀被盗的不足，本实用新型提供一种简易防盗闸阀，该实用新型不仅有防盗功能，而且还节约成本，使用简单安全。 
本实用新型解决其技术问题的技术方案是：将阀杆螺母外圆车制成螺纹连接在阀盖上部内侧，并用紧定螺钉固定；其次压盖通过反扣螺母固定在阀盖下部，压盖外圆和内孔用两“O”型密封圈与阀盖进行密封；再次阀盖与阀体连接处用“O”型密封圈密封；手轮通过平键与阀杆联接，并通过阀杆底部“凹”形的圆柱体带动闸板轴向移动，从而实现闸阀的开启和关闭。 
其动作原理如下：旋动手轮时，通过键带阀杆旋转，阀杆在阀杆螺母梯型螺纹内旋转，阀杆以阀杆螺母做为支点一边旋转一边上下运行，由于阀杆底部“凹”形的圆轴体在阀板的“T”型槽内，故带动阀板轴向移动，从而实现闸阀的开启和关闭。 
本实用新型与原有技术比较，将阀杆螺母移至阀盖内部并用螺纹连接其内， 并采用转动手轮直接带动阀杆来实现闸阀的开关，节省了一对轴承件，故具有结构简单、防盗、环保、节约成本的良好效果。 
附图说明：
下面结合附图和实施例对本实用新型作进一步说明。 
图1是本实用新型总装图 
在图1中：1、手轮压帽；2、键；3、手轮；4、阀杆螺母；5、紧定螺钉；6、阀盖；7、阀杆；8、压盖；9、阀板；10、阀座；11、阀体；12、“O”型密封圈；13、压盖内“O”型密封圈；14、压盖外“O”型密封圈 
具体实施方式：
在图1中：阀盖6与阀体11通过螺纹连接并用“O”型密封圈12密封，压盖8通过螺纹固定在阀盖底部，并用内“O”型密封圈13、外“O”型密封圈14密封阀杆7和阀盖6，阀杆7上部通过键与手轮连接，中部通过梯型螺纹与阀杆螺母4连接，而阀杆螺母4通过反扣螺纹与阀盖6连接，并用紧定螺钉5固定，阀杆7通过下部“凹”形的圆轴体与阀板9间隙联接。
