The utility model relates to an oil delivery joint of an oil extraction pump, the upper part of the main body has upper thread, the lower part of the main body has lower thread, the external part of the main body has upper section and lower section, the diameter of the lower section is larger than the diameter of the upper section, the transition section between the lower section and the upper section is tapered, the lower section has blind hole, and the transition section and the lower section are provided with a connecting groove, and the connecting groove is The number is 3 \u2011 4, and evenly distributed on the upper section and transition section. The connecting groove is connected with the blind hole. The connecting groove extends upward to the upper section. The upper end of the connecting groove is under the upper thread. After the connecting groove extends upward to the upper section, the liquid flow can flow through the connecting groove to the upper section and then Flowing to the annular space between the upper section and the pump barrel of the oil extraction pump, by lengthening the length of the connecting groove, the overflow area of the oil extraction joint of the oil extraction pump can be increased, and the liquid flow resistance can be reduced.

一种抽油泵出油接头
本技术是油田抽油用的设备,是抽油泵上的配件,具体是一种抽油泵出油接头。
技术介绍
抽油泵的出接头如图1所示,主体0的上部有上螺纹0-1,主体1的下部有下螺纹0-4,主体0的外部有上段0-5、下段0-7,所述的下段0-7的直径大于所述的上段0-5的直径,所述的下段0-7和所述的上段0-5之间的过渡段0-6为锥形,所述的下段0-7内有盲孔0-3,在所述的过渡段0-6、下段0-7处设置联通槽0-2,所述的联通槽0-2与所述的盲孔0-3联通,所述的联通槽0-2的上端与所述的上段0-5的下端相接。主体0安装在抽油泵的柱塞上端,抽油时处于抽油泵的泵筒内,下段0-7的外径与抽油泵的内径差只有0.5mm,因此,主体0处于抽油泵的泵筒内后实际的出油通道只有联通槽0-2的投影面宽度与所述的上段0-5和所述的下段0-7围成的范围,由于强度的问题,这个范围不可能过大,因此,现有的抽油泵的出油接头的过流面积小,液流阻力大,不利于抽油。
