    • A tool and a method for cutting holes in a container wall such as in a tank, a cistern, a pipeline, a vehicle, a ship, a production like or the like that contains inflammable, explosive, or other hazardous gasses, and liquids. The tool includes means for pressurising a cutting medium and discharging said medium via a nozzle. The nozzle is arranged in an enclosing cover including a scalable safety outlet for evacuation of the container contents. The cover has means of sealed-off abutment against the container wall concerned in the area in which hole cutting is to be performed. The nozzle is arranged to be directed towards the container wall in such a way that in use the cutting medium is discharged in the form of a jet impinging against the container wall with sufficient force to cut through said wall.
    • 一种用于切割容器壁中的孔的工具和方法,所述容器壁例如包含易燃,易爆或其他有害气体的液体,容器,水箱,管道,车辆,生产类似物等。 该工具包括用于对切割介质加压并经由喷嘴排出所述介质的装置。 喷嘴布置在包括用于排出容器内容物的可伸缩安全插座的封闭盖中。 所述盖具有与要在其中进行孔切割的区域中相关的容器壁的密封抵靠的装置。 喷嘴被布置成朝向容器壁指向,使得在使用中,切割介质以足够的力冲击抵靠容器壁的喷射器的形式排出以切穿所述壁。

    • An orifice holding spring disk. The spring disk is utilized to retain orifice(s) against a smooth flat platen surface. The spring disk may further comprise an inlet flow conditioning nozzle, provided in (a) a flow collimating configuration to produce a coherent flow waterjet, or (b) in a de-collimating configuration to produce a divergent waterjet. The spring disk has an annular outer ring, one or more through-holes, and counterbores to form wells in the spring disk. The wells are slightly larger in diameter than the particular orifice to be mounted and slightly shallower (in the water flow direction) than the thickness of the orifice. A nozzle cap compresses the platen and spring disc against a high pressure inlet tube. The outer diameter of the spring disk is forced to flex to the cap surface while the center portion is restrained by the orifice that is resting on the platen.
    • 孔保持弹簧盘。 弹簧盘用于将孔保持在光滑平坦的压板表面上。 弹簧盘还可以包括入口流调节喷嘴,其设置在(a)流动准直构造以产生一致的流水喷射器,或(b)以非准直构型产生发散的水射流。 弹簧盘具有环形外圈,一个或多个通孔和沉孔,以在弹簧盘中形成井。 孔的直径略大于要安装的特定孔,并且稍微比水口方向(在水流方向上)要小于孔的厚度。 喷嘴盖压靠压板和弹簧盘抵靠高压入口管。 弹簧盘的外径被迫弯曲到盖表面,而中心部分被搁置在压板上的孔限制。
