The invention is a mud nozzle which useful for cleaning mud between pipes located on nuclear vapour generator pipe plates. On the top of nozzle, there is a positioner. It comes near pipe row and move along plane vertical to column direction. Two ejectors/recievers on positioner emit signal and recieve reflected signal along axis of parallel to column plane. The distance between two axles is odd multiple of half of pipe pitch. Recieving signal must be minus a indicating signal of positions. In other hand, there are a ejector and reciever, which layout separately on moving direction of nozzle. Ejector give signal at the first given-direction, while reciever will recieve the reflected signal from seeondary given-direction. |
