摘要： A scale removing nozzle for removing scales on a metal surface by causing highly pressurized liquid to impact against the metal surface. Recently, in order to improve the scale removing performance, there is a demand for jetting ultra-highly pressurized water whose pressure is in the range of 30-100MPa, but ultra-highly pressurized water like this tends to badly damage an orifice portion of the nozzle and there has been no nozzle available having sufficient durability. In the scale removing nozzle, a concave portion (12) is formed in a leading end portion (11) in a liquid injecting direction of a nozzle main body (7), the concave portion being formed such that it gets smaller in diameter toward the upstream of the liquid injecting direction, the leading end portion (11) being formed annularly and integrally with the concave portion (12) such that the leading end portion surrounds the full outer circumference of the concave portion, an outlet side of an orifice (7b) being provided such that it opens along its full circumference toward the bottom side of the concave portion (12), whereby the wear resistance of the orifice at its circumferential portion against the ultra-highly pressurized water and durability can be provided, thereby making it possible to effectively prevent early failure.
摘要翻译：一种用于通过使高压液体冲击金属表面来去除金属表面上的氧化皮的除垢喷嘴。近来，为了提高除垢性能，需要喷射压力在30〜100MPa范围内的超高压水，但是这样的超高压水容易严重损坏喷嘴，并且没有可用的喷嘴具有足够的耐久性。在除垢喷嘴中，在喷嘴主体（7）的喷液方向上的前端部（11）上形成有凹部（12），该凹部形成为朝向在喷射方向的上游，前端部（11）与凹部（12）环形地一体地形成，使得前端部围绕凹部的整个外周，孔口（7b）的出口侧）设置成使得其沿着其整个周边朝向凹部（12）的底侧开口，由此可以提供孔周围部分处的孔抵抗超高压水和耐久性的耐磨性，从而使其有可能有效预防早期失败。

摘要： A descaling nozzle having a straightening passage incorporating a straightener, a constricted passage communicating with a downstream side of the straightening passage and a jetting passage communicating with a dowstream side of the constricted passage. The jetting passage has a jetting opening at a bottom of a groove defined at a top end face thereof in the direction of diameter of the same. Axes of the straightening, constricted and jetting passages are aligned on the same straight line. The straightening passage has the same radius through its whole or substantially whole length and the constricted passage has a radius tapering from its upstream end to its downstream end or to a vicinity of the same.

摘要： The invention relates to a directing passage (A) containing a compensating element (4), a constricted or throttling passage (B) communicating with the downstream side of the directing passage (A), and a jet passage (C) communicating with the downstream side of the throttling passage (B) and having a spray or jet opening (C1) at the underside of a recess (3a) formed on an upper end face of said jet passage in the direction of its diameter, the axes of directing, throttling and jet passage each being aligned on the same axis, and the special feature consisting in that the directing passage (A) has a constant radius over its entire length or virtually over its entire length and the throttling passage (B) has a radius which gets smaller from its upstream end down to its downstream end or to the vicinity thereof.
