Abstract

本实用新型公开了一种用于石油钻采作业的低压垂击由壬四件套,包括连接公接头、密封圈、压环、连接螺母、连接管。公接头接触的密封圈一侧与压环相接,公接头与连接螺母通过螺纹连接,通过旋进连接螺母推动压环压紧密封圈,便其产生向内变形,压紧连接管,实现连接公接头和连接管的密封连接。其优点是螺母旋转扭矩小,密封可靠,安装拆卸方便。密封压力可达1MPa。

Description

低压垂击由壬四件套
技术领域:
本发明涉及接头,使用于石油钻井作业的泥浆净化系统上。 
背景技术:
目前用在石油钻井作业的低压管线接头是气胎式由壬,其不足之处是气胎易爆破或漏气,造成管线密封失效,并且更换气胎困难,泥浆损失大。 
发明内容:
本发明目的是提供一种拆装便捷、密封可靠的低压垂击由壬四件套。 
为了达到如上目的,本发明采取如下技术方案:它包括公接头、密封圈、压环、连接螺母,公接头接触密封圈的一侧与压环相接,公接头与连接螺母通过螺纹连接。 
本发明的进一步技术方案在于:所述连接螺母有可被敲击的凸翼结构。 
采用如上技术方案的低压垂击由壬四件套,具有如下有益效果:本发明所述的接头,螺母旋转扭矩小,密封可靠,安装拆卸快捷。适应性强,维护简便。用小榔头锤击几下有凸翼结构的连接螺母,即可可靠密封,密封压力可达1MPa。 
附图说明:
为了进一步说明本发明,下面结合附图进一步进行说明: 
附图为发明的结构示意图: 
其中:1公接头;2密封圈;3压环;4连接螺母;5连接管。 
具体实施方式:
如图所示,本发明所述的低压垂击由壬四件套,它包括公接头1、密封圈2、压环3、连接螺母4,公接头1接触的密封圈2一侧与压环3相接,公接头1与连接螺母4通过螺纹连接。 
其结构原理是公接头1的一端与容器或钢管焊接,公接头1和连接螺母4通过螺纹连接,连接螺母4旋进时,推动压环3压紧密封圈2产生向内变形,压紧连接管5,实现公接头1和连接管5的密封连接。 
所述压环3使得密封圈被挤压严密,因此密封效果更好,并使连接螺母4旋进时扭矩小。 
所述连接螺母4有可被敲击的凸翼结构,可使连接螺母旋紧可靠。 
以上显示和描述了本发明的基本原理、主要特征和本发明的优点。本行业的技术人员应该了解,本发明不受上述实施例的限制,上述实施例和说明书中描述的只是说明本发明的原理,在不脱离本发明精神和范围的前提下本发明还会有各种变化和改进,这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等同物界定。
