関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an injection nozzle device, and more particularly, a multistage injection nozzle suitably used as a high-pressure water injection device in a water jet injection device. It is related to the device.
従来より、高圧水を噴射するウォータージェット噴射装
置は、対照物の洗浄から切削加工まで広範な用途に採用
され需要者の便宜に供されている。BACKGROUND ART Water jet spraying devices that spray high-pressure water have been used for a wide range of purposes, from cleaning objects to cutting, and have been used for the convenience of consumers.
ところで、この種のウォータージェット噴射装置におけ

要があり、従って、作業に手間どるだけでなくこのよう
な操作を機械的に行うように構成すると製造コストが嵩
み保守管理も面倒になる等種々の問題点を有していた。By the way, since the injection port of the nozzle device in this type of water jet injection device is extremely narrow,
For example, when cleaning a relatively wide area on a target object, it is necessary to move the entire nozzle device back and forth, and therefore, it is not only time-consuming to perform the work, but it is also preferable to configure such operations to be performed mechanically. It has had various problems, such as increased manufacturing costs and troublesome maintenance.
そこで、この発明は、内部に流体送給路を形成した装置
本体に複数の噴射ヘッドを直列に装着し、これらの噴射

うにしたものである。Therefore, the present invention has a device main body having a fluid feed path formed therein, in which a plurality of ejection heads are mounted in series, and these ejection heads have one or more ejection heads that are offset at a predetermined angle with respect to the axis of the fluid feed path. The injection channels are bored facing each other, and one end of each injection channel is connected to the fluid supply channel of the device main body, and an injection nozzle is attached to the other end to produce multiple streams of high-pressure water biased at a predetermined angle. By configuring the jet to be injected in multiple stages, it is possible to easily perform work over a relatively wide range.

に作業の簡便化を図ることができる。In addition, the plurality of jetting heads in the multi-stage jetting nozzle device configured as described above are rotatably mounted on the main body of the device, and the fluid jetting directions of the jetting nozzles forming a pair of each jetting head are symmetrical with respect to the circumferential direction. The work can be further simplified by configuring each injection head to be rotated by the injection reaction force while being deviated by a predetermined angle.

。In addition, in the injection nozzle device configured as described above, the injection channels for each pair may be arranged centrally at a predetermined location of the fluid feeding path formed in the device body, or arranged in the axial direction of the fluid feeding path. The fluid jetting direction of the pair of jetting nozzles attached to each jetting head can be biased symmetrically with respect to the circumferential direction, and the jetting head can be rotated in different directions. It can also be configured.

射ヘッドを旋回させながら広い範囲に噴射される。According to the multi-stage injection nozzle device according to the present invention, the high-pressure water supplied to the injection waterway of each injection head via the fluid supply path of the device main body is such that the injection direction of each injection nozzle is aligned with the axis of the fluid feed path. Since it is inclined at a predetermined angle, it is sprayed over a wide range and in multiple stages. In addition, if the fluid jet direction of the jet nozzle is symmetrical with respect to the circumferential direction and deviated by a predetermined angle, the high-pressure water is jetted over a wide range while rotating each jet head due to the action of the jet reaction force. .
