    摘要： Well tools comprising a go-devil actuated well safety valve, a locking assembly for releasably locking the safety valve at a desired depth in a well, running and pulling tools for installing and removing the safety valve, a go-devil ball for closing the safety valve, and apparatus for dropping the go-devil ball into a well under pressure and for retrieving the ball. The go-devil safety valve is mounted above the locking assembly and includes a trigger type latch which is released from above by the impact of the go-devil ball. The valve may be reset for reopening the valve without removal of the valve from the well bore by means of a special reset and pulling tool disclosed herein. The go-devil valve is installed in a well, preferably above a storm choke, to shut the well in under emergency conditions which releases the go-devil ball at the surface in response to hazardous conditions such as fire. The go-devil ball drops to the go-devil valve which closes in response to the impact of the ball.

    摘要翻译： 井工具包括恶魔致动井安全阀，用于将安全阀可释放地锁定在井中所需深度的锁定组件，用于安装和拆卸安全阀的运行和拉动工具，用于关闭安全阀的恶魔球 阀，以及用于在压力下将恶魔球放入井中并用于回收球的装置。 恶魔安全阀安装在锁定组件的上方，并包括一个触发式闩锁，该触发式闩锁由于恶魔球的冲击从上方释放。 可以通过本文公开的特殊的复位和拉伸工具来复位阀门以重新打开阀门，而不用从井孔中移除阀门。 恶魔阀安装在井中，优选地在风暴扼流圈之上，以在紧急情况下关闭井，以在诸如火灾的危险条件下释放表面上的恶魔球。 恶魔球掉落到响应于球的冲击而关闭的恶魔阀门。

    摘要： A tool for lowering or raising a safety device in an oil well comprises a hollow cylindrical body, a plunger which reciprocates axially in said body in response to fluid pressure pulses, means for converting the axial movement of said plunger to rotary movement of a rotatable member, and nut and screw means for converting the rotary movement of said rotating member to axial movement by a screw which actuates pincer means.
