ことになる。Nozzles with various hole diameters are effectively used depending on the purpose and conditions of use. Among these nozzles, which are mainly used for cleaning at relatively high pressures of, for example, 5 MPa or more, have small pore diameters, and because of their diameters, nozzles of less than mm are often used, and it is not uncommon for nozzles to have diameters of less than 1 mm. However, the smaller the nozzle opening (1), the more likely it is to be clogged by actual objects in the fluid, resulting in poor cleaning and a decline in product quality. Special &, -i$ (7) 9 If fluid jet cleaning is incorporated as one process in a 5-in-1 construction, it is cumbersome to stop only the cleaning process and inspect the nozzles, and it is difficult to shorten a large number of nozzles. It is extremely difficult to inspect and repair in time. Similarly, nozzles mainly used for cutting at high pressures of 100 MPa or higher have historically had smaller pore diameters than the cleaning nozzles, with most having a diameter of 1 mm or less, and therefore are more likely to clog and are not incorporated into production lines. In this case, the same problem as cleaning occurs.

構成されて管部材６を連結して成る。The principle of the method used in the present invention is generally known as an injection pump or ejector, in which fluid ejected from a nozzle removes the atmosphere surrounding the jet, thereby creating a negative pressure area around the jet. This device takes advantage of the fact that the negative pressure is generated, activates the negative pressure display device, and uses the display device to prevent nozzle clogging.
This will be explained in detail with reference to the illustrated embodiment. In the figure, reference numeral 1 denotes a nozzle, which is fixed to a conduit 3 with a cap nut 2. Reference numeral 4 is a differential user attached to the nozzle 1, which locks a pipe member 6 communicating with the chamber 5. Reference numeral 10 denotes a display device, which is composed of a display member 11, a transparent cover 12, and a spring 13, and is connected to a tube member 6.
さて、導管３から流体を送りノズル１から噴射すると噴
流２０の周囲の大気は噴流２０に引きずられて流れる。Now, when fluid is sent from the conduit 3 and injected from the nozzle 1, the atmosphere around the jet 20 is dragged by the jet 20 and flows.
すなわち室５内の大気が噴流２０によって運び去られる
。室５は周囲の大気が流入しないように構成されている

れてしまうと、矢Ａの方向から視る場合表示部材１１は
見えないため表示されないということになる。That is, the atmosphere within the chamber 5 is carried away by the jet 20. Since the chamber 5 is configured to prevent ambient air from flowing in, the air inside the chamber 5 is removed by the jet 20, creating a negative pressure inside the chamber 5, and this negative pressure continues as long as the jet 20 continues. It is something to do. The chamber 5 is connected to the display device 10 by a tube member 6, so that the chamber 15 of the display device 10 also has a negative pressure, and the display member 11 is pulled upwards against the spring 13. Here, the transparent cover 12 of the display device 10 is provided with a through hole 14 so that the chamber 16 is always in communication with the atmosphere. is configured so that it does not change. If the display member 11 is pulled upward in this way, the display member 11 cannot be seen when viewed from the direction of arrow A, and is therefore not displayed.

れば表示された状態となる。Next, when the injection of fluid from the nozzle 1 is stopped, the atmosphere flows into the chamber 5 and becomes equal to the atmospheric pressure. Similarly, the chamber 15 of the display device 10 through the pipe part 6 also becomes atmospheric pressure, so that the display member 11 It is pressed by the spring 13 and descends, and when viewed from arrow A, it becomes the state shown.

果的に表示することが可能である。If the nozzle 1 is completely blocked by a foreign object, etc. and the fluid is no longer ejected, it will be displayed as fluid ejection has stopped due to the action described above, and clogging will be detected.On the other hand, if the nozzle 1 is completely blocked by a foreign object If the nozzle is clogged or the blockage is not complete and some fluid is ejected from the nozzle 1, the amount of water emitted is small and the negative pressure generated in the nozzle 5 is smaller than when the fluid is ejected normally. Although there may be cases where sufficient negative pressure is not obtained to pull up the display member 11 of the display section w10, it is possible to display the display effectively by adjusting the strength of the spring 13 or the like.
