Abstract

本实用新型公开了一种油嘴套内的油嘴式单流阀,它由阀体、凡尔球、连接丝扣、出油孔、弹簧、调压盖组成,阀体为空心圆柱形结构,在阀体上加工有均匀分布的出油孔,阀体一端加工有连接丝扣,在阀体内靠近连接丝扣处加工有内圆锥面,凡尔球坐于该圆锥面上,弹簧顶在凡尔球上,调压盖上紧在阀体的另一端并压在弹簧上。本实用新型结构简单,安装维护方便,能有效控制抽油机光杆断时引起的管线原油的倒流和大面积环境污染。

Description

油嘴式单流阀
技术领域  本实用新型涉及一种连接抽油机井井口与集油干线的控制阀。
背景技术  目前,抽油机井占总井数90%,由于高含水低产井比例增加,油井提液量越来越大,使抽油机井光杆载荷越来越大,导致抽油机井光杆断裂频率增加。现场用单流阀安装在计量站后油井管线上,防止光杆断后管线内原油倒流而造成大面积污染,其缺点:采用焊接或卡箍连接安装,安装时需停井并管线放空,安装时间长,出砂井砂埋砂卡;检查时重复安装,管理不方便;造价高不易检查更换。如果光杆断裂落入井口盘根盒以下,用人工关闸门控制,由于发现不及时,就会导致油井集油干线中的原油倒流喷出井口,造成大面积污染。
发明内容  本实用新型的目的是提供一种在光杆断裂落入井口盘根盒以下时、能及时控制集油干线中的原油倒流且安装更换方便的油嘴式单流阀。本实用新型是这样实现的,它由连接丝扣、凡尔球、阀体、出油孔、调压盖、弹簧组成。该实用新型为中空圆柱形结构,阀体为中空圆柱体,在阀体上加工有出油孔,阀体一端加工有连接丝扣,在阀体内与连接丝扣相接的部位加工有圆环锥面,凡尔球坐于该锥面上,弹簧从一侧顶在凡尔球上,调压盖安装在阀体的另一端并压紧在弹簧上。它是利用油嘴套内丝扣安装单流阀,用丝扣连接,放在油嘴套内,代替油嘴位置空间。抽油机井井口油嘴套内不装油嘴,装油嘴丝扣闲置。本实用新型适用于采油树带油嘴套的油井,它利用油嘴套装油嘴的原理,使操作使用更加简单可靠,可有效防止光杆断管线内原油倒流而造成大面积污染。
附图说明  图1为本实用新型的剖面图。图中:1-连接丝扣、2-凡尔球、3-阀体、4-出油孔、5-弹簧、6-调压盖。
具体实施方式  参照附图1,油嘴式单流阀由连接丝扣1、凡尔球2、阀体3、出油孔4、弹簧5、调压盖6组成。阀体3为空心圆柱体,在阀体上均匀地加工有出油孔4,在阀体3内靠近连接丝扣1的部位加工有内锥面,凡尔球2可在其中滚动,凡尔球直径大于连接丝扣1的内径,连接丝扣被加工在阀体3的一端,在阀体3内,弹簧5顶在凡尔球上,调压盖6拧在阀体3的另一端,并顶紧在弹簧5上。组装特征:调压盖6用于调节弹簧5,用套筒扳手将连接丝扣1与油嘴套内丝扣连接上紧,再上油嘴套丝堵。安装步骤,停井→关生产闸门→关回压闸门→开取样闸门放空→卸下丝堵→用套筒扳手上单流阀;使用时,上丝堵→关取样闸门→开生产闸门→开回压闸门→开井。
