NOZZLE FOR WASHING INSIDE PIPE, PRESSURE SWITCHING VALVE, AND PRESSURE SWITCHING WASHING METHOD FOR DRAIN PIPE
To provide a nozzle for washing the inside of a pipe, that improves reliability of switching operation in an injection direction.SOLUTION: A nozzle 5 for washing the inside of a pipe is attached to a tip part of a water supply hose 6 and can selectively inject high-pressure water sent through the water supply hose from a first injection port 5i or a second injection port 5k having a different injection angle with respect to an axial line Ax1 of a nozzle body 5A. In the nozzle body, a cavity part 5f with a direction along the axial line Ax1 as a longitudinal direction is formed, and a ball-shaped sealing body 5e housed within the cavity part and moving along the longitudinal direction within the cavity part by receiving gravity is provided. The high-pressure water is selectively jetted from the first injection port or the second injection port by movement of the sealing body within the cavity part 5f due to the gravity.SELECTED DRAWING: Figure 2
【課題】噴射方向の切替動作の信頼性を向上させた管内洗浄用ノズルを提供すること。【解決手段】送水ホース６の先端部に取り付けられ、送水ホースを介して送られる高圧水をノズル本体５Ａの軸線Ａｘ１に対して互いに噴射角度が異なる第１噴射口５ｉまたは第２噴射口５ｋから選択的に噴射可能にした管内洗浄用ノズル５であって、ノズル本体内には、軸線Ａｘ１に沿う方向を長手方向とした空洞部５ｆが形成されると共に、空洞部内に収容されて、重力を受けて前記空洞部内を長手方向に沿って移動するボール状の封止体５ｅが備えられる。この封止体の重力による空洞部５ｆ内の移動により、第１噴射口又は第２噴射口から選択的に高圧水が噴射される。【選択図】図２
