Abstract

本实用新型公开了一种防卡堵式单流阀,主要包括上工作筒、下工作筒、防进球座和连接套,其特点是在防进球座的内腔中固定有阀座,在阀座的上部密封面处设置有钢球,在钢球的上方固定有压盖,在连接套与下工作筒间设置有防砂滤网。本实用新型结构简单,使用方便,能在下分层注水管柱时有效防止杂物将钢球与阀座卡死,确保反洗井通道的畅通。

Description

防卡堵式单流阀
一、技术领域:本实用新型涉及一种油田注水用井下工具,特别涉及一种防卡堵式单流阀。
二、背景技术:目前,油田所使用的单流阀,在下分层注水管柱时容易产生垢片、胶皮等杂物堵死单流阀的现象,造成反洗井无法进行,不仅浪费了工时,而且增加了生产成本。
三、发明内容:本实用新型的目的就在于提供一种能防止杂物堵死单流阀、反洗井可正常开启的装置——防卡堵式单流阀。本实用新型的技术解决方案是:所述防卡堵式单流阀,主要包括上工作筒、下工作筒、防进球座和连接套,在防进球座的内腔中固定有阀座,在阀座的上部密封面处设置有钢球,在钢球的上方固定有压盖,在连接套与下工作筒间设置有防砂滤网;在阀座与防进球座之间设置有密封胶圈。本实用新型结构简单,成本低廉,使用方便,能在反洗井时有效过滤井内的垢片、胶皮等杂物,避免杂物将单流阀堵死,确保反洗井通道的畅通。
四、附图说明:图1是本实用新型实施例主视结构半剖示意图。
五、具体实施方式:参照附图,所述防卡堵式单流阀主要包括上工作筒1、下工作筒2、防进球座3和连接套5,在防进球座3的内腔中采用销钉固定有阀座7,在阀座7的上部密封面处设置有钢球4,在钢球4的上方固定有压盖6,在连接套5与下工作筒2间设置有防砂滤网8,能将井内的垢片、胶皮等杂物过滤。在阀座7与防进球座3之间设置有密封胶圈9。
