ノズルヘツドが装備される。 The pipe inner circumferential surface cleaning device inserts the pipe inner circumferential surface cleaning nozzle head equipped therein into the inner diameter of the pipe, sprays a jet stream of cleaning fluid from the nozzle hole onto the pipe inner circumferential surface, and cleans the pipe inner circumferential surface. Cleaning is in progress. The pipe inner circumferential surface cleaning apparatus is conventionally equipped with a pipe inner circumferential surface cleaning nozzle head shown in FIGS. 1 and 2.

装置が複雑になる。 The pipe inner peripheral surface cleaning nozzle head shown in FIG. 1 has a large number of nozzle holes 4 equally spaced on the circumference of an inclined surface between a large diameter part 1 and a small diameter part 2, and which communicate with a flow passage 3. The high-pressure cleaning fluid that is force-fed into the flow path 3 is diffused and sprayed radially toward the inner circumferential surface of the pipe to clean the inner circumferential surface. In the case of this nozzle head for cleaning the inner circumferential surface of the pipe, a considerable number of nozzle holes 4 are required to uniformly cover the inner circumferential surface of the pipe with a jet stream of cleaning fluid in the circumferential direction. Therefore, in order to obtain a predetermined injection pressure, the nozzle hole 4 must be made smaller, which may cause clogging, and if clogging occurs, the flow rate and pressure of the cleaning fluid will change. On the other hand, if the number of nozzle holes 4 is reduced, uneven cleaning will occur, and in order to uniformly clean the inner circumferential surface of the pipe, the inner circumferential surface of the pipe cleaning nozzle head,
Alternatively, it is necessary to rotate one of the pipes during cleaning, which complicates the pipe inner peripheral surface cleaning device and the pipe clamping device.

を有する。 The pipe inner circumferential surface cleaning nozzle head shown in FIG. 2 compensates for the drawbacks of the pipe inner circumferential surface cleaning nozzle head described above. An annular nozzle interval 8 communicating with the flow passage 7 is formed between the pipe and the inclined end face, and the cleaning fluid forced into the flow passage 7 is diffused and sprayed in a bowl shape toward the inner circumference of the pipe to clean the inner circumference. Let's do it. For this pipe inner surface cleaning nozzle head,
Although it is not necessary to rotate itself and its pipe partner during cleaning, since the opening area of the annular nozzle gap 8 is large, the flow rate of the cleaning fluid must be increased, which is uneconomical. Furthermore, if the annular nozzle spacing 8 is narrowed too much in order to reduce the flow rate of the cleaning fluid, it will wear out, resulting in frequent fine adjustments due to the wear and disadvantages such as difficulty in adjustment.

い。 Therefore, the ability to clean the inner circumferential surface of the pipe is dramatically improved, and the entire circumference of the inner circumferential surface of the pipe can be covered with the jet stream from the minimum required number of fan-shaped nozzles. As a result, there is no need to rotate the pipe inner circumferential surface cleaning nozzle head or the pipe during cleaning, which simplifies the structure of the pipe inner circumferential surface cleaning device and the pipe holding mechanism. Furthermore, by providing the minimum required number of fan-shaped nozzles, the flow rate of the cleaning fluid can be reduced, and the nozzle holes do not need to be made extremely small, so there is no need to worry about clogging of the nozzle holes.
