Abstract

该高强度低扭力旋塞阀，包括主体，主体的内部装有上、下阀座及球座，球座、旋钮A、B被卡在阀座外套内的固定位置上，阀座外套被装在主体内，并被调节螺母所限位，而旋钮A被卡在旋钮的凹槽内，装在主体的侧面孔内，使用时，将高强度低扭力旋塞阀装在井口油管上，当有压力上涌时，用扳手旋动旋钮，旋钮连接旋钮A、B，推动球座一起转动，当旋至“关”位置时，球座刚好关闭主体的内通径，此时可控制井内压力上涌；当需要泄压时，扳动旋钮，此时，球座上的小眼起到连通作用，把高的压力源连通到阀座外套与主体间的空隙中，旋钮A、B所受压力与球座所受压力达平衡，此时只需较低的扭力，即可扳动旋钮旋，打开主通径，实现安全放喷，保证施工安全。

Description

高强度低扭力旋塞阀
技术领域
本发明涉及油田作业领域所用的一种手动控制阀设备，一种高强度低扭力旋塞阀。
技术背景
目前，在抽油机修井作业施工过程中，易发生管柱内流动的液体涌向井口，发生井喷，施工过程具有一定的危险性，而常规旋塞阀可关闭旋塞阀，控制井喷，但当井内压力达到10Mpa以上时，若要实施放喷，常规旋塞阀受井内压力影响，无法打开开关，因而无法保证施工的进行。
发明内容
为了解决背景技术中的问题，本发明提供一种新的手动控制阀设备，高强度低扭力旋塞阀，该高强度低扭力旋塞阀在抽油机修井作业施工过程中，能快速关闭管柱内流动的液体，防止井喷，当井内压力较高时，此时若要实施放喷，用扳手旋动旋钮，且在旋动过程中，只需较低的扭力，即可打开开关，实现放喷，起到安全施工的目的。
本发明的技术方案是：该高强度低扭力旋塞阀包括主体，主体的侧面有一旋钮开关孔，主体的内部装有上、下阀座，上下阀座的中间夹一球座，球座的上下被卡在旋钮A及旋钮B内，旋钮A及旋钮B被装在阀座外套上，阀座外套又装在主体内，并被调节螺帽所限位，而旋钮A被卡在旋钮凹槽内，旋钮装在主体侧面的旋钮孔内。
本发明具有如下有益效果：耐压达70Mpa，在此强压力下，开闭旋钮，扭力仅为10-12N.M，能在强压下快速安全的放喷，保证施工安全。
附图说明
附图是本发明的半剖视图：
图中：1、主体  2、阀座外套  3、下阀座  4、球座5、旋钮  6、旋钮A  7、旋钮B  8、上阀座  9、调节螺母
具体实施方式
下面结合附图对本发明作进一步说明：如附图中所示，该高强度低扭力旋塞阀，包括主体1，主体1的侧面有一旋钮开关孔，主体的内部装有下阀座3及上阀座8，上阀座8和下阀座3之间夹一球座4，球座4的上下有凹槽，被卡在旋钮A6及旋钮B7上，旋钮A6及旋钮B7又被卡在阀座外套2内的固定位置上，阀座外套2被装在主体1内，并被调节螺母9所限位，而旋钮A6被卡在旋钮5的凹槽内，旋钮5装在主体1的侧面旋钮孔内，实际使用时将高强度低扭力旋塞阀装在井口油管上(公扣头向下)，当井下出现异常现象，有压力上涌时，可迅速用扳手旋动旋钮5，在此过程中，旋钮5连接旋钮A6及旋钮B7，推动球座4一起转动，当旋钮5旋至“关”位置时，球座4刚好关闭主体1的内通径，即关闭高强度低扭力旋塞阀，此时可控制井内压力上涌现象，当需要释放井内压力源时，用扳手扳动旋钮5，在此过程中，球座4上的小眼起到连通作用，把高的压力源连通到阀座外套2与主体1间的空隙中，旋钮A6及旋钮B7所受压力源的压力与球座4所受压力源的压力达平衡，旋钮5连接旋钮A6及旋钮B7，推动球座4一起转动，只需较低的扭力，即可将旋钮5旋至“开”位置，球座4刚好开通主体1的内通径，实现安全放喷，保证施工安全。
