Abstract

本实用新型涉及一种外剪式泄油器，适用于石油采油作业。目前使用比较多的内剪式泄油器，由于设计的原因，经常出现反工现象影响工期，给操作人员带来许多不便。外剪式泄油器弥补了现有技术的不足，采用了一种新的设计思想设有与下井管柱联接的上接头外套，外套与装有空心泄油钉的内套锥面摩擦连接，泄油时外套剪断泄油钉，达到泄油的目的。具有结构简单、下井操作方便、可进行多次修复使用的特点。

Description

外剪式泄油器
本实用新型涉及一种外剪式泄油器，适用于石油采油作业。
目前，在石油采油作业中使用比较广泛的泄油器为内剪式，需用抽油杆开启泄油；但由于配管柱失误造成打开泄油器抽油杆节箍刮开泄油器，油管结蜡造成开闭器下不去的情况经常发生。还有抽油杆脱扣时对扣，上提校紧时打开泄油器或下泄油器不下开闭器，而影响泄油和抽油杆断脱影响泄油的情况时有发生。
本实用新型的目的是要提供一种外剪式泄油器，不但结构简单，下井操作方便，还可多次修复使用，弥补了现有技术中经常反工，操作不便的缺点。
本实用新型的目的是这样实现的：与下井管柱联接的上接头(1)与外套(2)螺纹连接其间装有密封圈(7)，外套(2)和内套(3)间装密封圈(8)并锥面摩擦连接，安全销钉(4)将外套(2)与内套(3)定位，空心泄油钉(5)通过密封圈(9)、挡圈(10)与内套(3)螺纹连接，下接头(6)与内套(3)固配合。泄油时外套(2)靠重力剪断安全销钉(4)及空心泄油钉(5)达到泄油的目的。
本实用新型的特点是构思独特、结构简单、下井操作方便，可进行多次修复使用，在石油采油作业中有广泛的应用前景。
下面将结合附图对本实用新型作详细说明。
图1是本实用新型的主视图，也是本实用新型的具体实施例。
参照图1、与下井管柱联接的上接头1与外套2螺纹连接其间装有密封圈7，外套2和内套3间装密封圈8并锥面摩擦连接，安全销钉4将外套2与内套3定位，空心泄油钉5通过密封圈9、挡圈10与内套3螺纹连接，下接头6与内套3固配合。泄油时外套2靠重力剪断安全销钉4及空心泄油钉5达到泄油的目的。
