INJECTION NOZZLE OF WELLHOLE WASHING DEVICE
To provide an injection nozzle of a cleaning device for washing off dirt adhering to an inner peripheral surface of a deep well pipe by injecting high pressure water into the inner peripheral surface, wherein the injection nozzle is not damaged even if high-pressure water hits the inner peripheral surface because the cleaning device is displaced from a central axis of the deep well pipe.SOLUTION: A recessed part 16 is provided in a tip part 12 of the injection nozzle 3 and a tip nozzle 17 is fitted and attached to the recessed part 16 so that the tip nozzle 17 does not protrude from a tip 21 of the tip part 12.SELECTED DRAWING: Figure 5
【課題】 深井戸管の内周面に高圧水を噴射して付着した汚れを洗い落とす為の洗浄装置の噴射ノズルであって、洗浄装置が深井戸管の中心軸から位置ズレして内周面に当たっても破損しない噴射ノズルの提供。【解決手段】 噴射ノズル３の先端部１２には凹部１６を設け、この凹部１６に先端ノズル１７を嵌めて取付け、先端部１２の先端２１から先端ノズル１７が突出しないようにしている。【選択図】 図５
