Abstract

方便连接具自灌功能的浮箍浮鞋芯体,它包括有由阀座(1)、承接套(2)、阀芯(3)和弹簧(4)构成的浮箍浮鞋芯体,阀座(1)外壁上设有连接螺纹(11)和密封圈槽(12),阀芯(3)的阀杆(31)尾部通过螺纹(32)固定有连接杆(5),连接杆(5)上套有通过销杆(6)固定在其上的泄压盘(7),阀杆(31)上从泄压盘(7)到承接套(2)依次套有密封垫(8)和垫环(9)。它与壳体连接方便,与壳体间密封性好,承受回压力大且具有自灌功能,它还具有结构简单造价低、使用安全可靠的优点,不安装连接杆、泄压盘、密封垫和垫环即可作非自灌强封式使用。

Description

方便连接具自灌功能的浮箍浮鞋芯体
技术领域
本实用新型涉及石油钻井用浮箍浮鞋芯体。
背景技术
浮箍浮鞋芯体是油田固井用浮箍浮鞋的主要部件,现有浮箍浮鞋芯体或与壳体连接不方便,或与壳体间密封性不好,或承受回压力小,或不具有自灌功能。
实用新型内容
本实用新型的目的是提供一种与壳体连接方便、与壳体间密封性好、承受回压力大且具有自灌功能的方便连接具自灌功能的浮箍浮鞋芯体。
本实用新型的技术解决方案是:它是在已有由阀座、承接套、阀芯和弹簧构成的浮箍浮鞋芯体的阀座外壁上设有连接螺纹和密封圈槽,阀芯的阀杆尾部通过螺纹固定有连接杆,连接杆上套有通过销杆固定在其上的泄压盘,阀杆上从泄压盘到承接套依次套有密封垫和垫环。
本实用新型的技术效果是:它与壳体连接方便,与壳体间密封性好,承受回压力大且具有自灌功能,它还具有结构简单造价低、使用安全可靠的优点,不安装连接杆、泄压盘、密封垫和垫环即可作非自灌强封式使用。
附图说明
附图为本实用新型实施例剖视图。
具体实施方式
如图所示,它是在已有由阀座1、承接套2、阀芯3和弹簧4构成的浮箍浮鞋芯体的阀座1外壁上设有连接螺纹11和密封圈槽12,阀芯3的阀杆31尾部通过螺纹32固定有连接杆5,连接杆5上套有通过销杆6固定在其上的泄压盘7,阀杆31上从泄压盘7到承接套2依次套有密封垫8和垫环9。阀杆31上密封垫8和垫环9之间套有弹簧垫10。
