Abstract

帽形活门开关,属油田井下阀门。它包适有上接头1、下接头2和位于上接头1和下接头2内的门座3、帽形门4及连接门座3和帽形门4的绞链5,其特征是它还具有可使帽形门4保持打开状态的限位器6;具有可将限位器6送入帽形门4处且可由限位器6穿过的短节7;绞链5上设有可对帽形门施加关闭力的扭簧8;上接头1上设有可使限位器6定位的环形卡槽9。它具有不需压井可完成向井内下入和可由井内起出抽油杆和油管作业的优点。

Description

帽形活门开关
本实用新型属一种油田井下阀门。
目前已有专利号为92202928.8，名称为“帽形活门”的专利，它是在由上接头和下接头连接而成的接头内设有形状近帽形的活门，打开时它可使抽油杆和油管由其通过，它实现了不需压井可向井内下入抽油杆和油管的作业，但由于其为一次性常开阀，它不能在抽油杆和油管向上起出时再将活门关闭，即它不能完成不需压井可由井内起出抽油杆和油管的作业。
本实用新型的目的是提供一种不需压井可完成向井内下入和可由井内起出抽油杆和油管作业的帽形活门开关。
本实用新型是这样实现的：它包适有上接头、下接头和位于上接头和下接头内的门座和帽形门及连接门座和帽形门的绞链，其特征是它还具有可使帽形门保持打开状态的限位器：具有可将限位器送入帽形门处且可由限位器穿过的短节；绞链上设有可对帽形门施加关闭力的扭簧；上接头上设有可使限位器定位的环形卡槽。
本实用新型的技术效果是：它具有不需压井可完成向井内下入和可由井内起出抽油杆和油管作业的优点。
图1为本实用新型实施例半剖结构图。
图2为本实用新型实施例服位器剖视结构图。
实施例：如图1和图2所示，它包适有上接头1、下接头2和位于上接头1和下接头2内的门座3和帽形门4及连接门座3和帽形门4的绞链5，其特征是它还具有可使帽形门4保持打开状态的限位器6；具有可将限位器6送入帽形门4处且可由限位器6穿过的短节7；绞链5上设有可对帽形门施加关闭力的扭簧8；上接头1上设有可使限位器6定位的环形卡槽9。限位器6为管壁上部和下部分别具内弹爪10和外弹爪11的圆筒状体。短节7为两端分别具内螺纹接头12和外螺纹接头13的杆状体。
