摘要： A side-entry sub for use in conjunction with wireline cable. The sub has a cable entry port provided with a self-closing valve for sealing the port upon withdrawal of the cable. In one embodiment, the self-closing valve is characterized by a housing member supporting a closure disc which is integrally molded with a resiliently deflectable support member having an elastic memory which biases the valve in the closed position. In an alternate embodiment, the self-closing valve comprises a ball valve, biased in the closed position by magnetic or spring means, and having a passageway through which the cable may pass. When the cable is inserted through the passageway, the ball valve is held in the valve open position. When the cable is removed from the passageway, the ball valve automatically closes.

摘要： Disclosed is a side entry sub with tension release wireline cable clamp. The side entry sub includes a tubular member having a port for the passage of the wireline cable into the interior of the tubular member. A cable clamp holder is positioned on the tubular member adjacent the port. The cable clamp holder has an axially extending passage with a cable clamp mounted therein. The cable clamp includes two clamp parts that are adapted to grip the cable therebetween. The cable clamp parts are movable from a gripping position to a releasing position responsive to axial movement with respect to each other in the clamp holder passage.
摘要翻译：公开了一种具有张力释放电缆线夹的侧入口。侧入口部分包括管状构件，该管状构件具有用于使电缆线缆通过管状构件内部的端口。电缆夹夹持器邻近端口定位在管状构件上。电缆夹夹具具有轴向延伸的通道，其中安装有电缆夹。电缆夹包括两个适于在其间夹持电缆的夹具部件。电缆夹部件能够在夹持保持器通道中相对于彼此的轴向移动而从夹持位置移动到释放位置。
