Position, the direction of the turntable 11, and the position of the base 1 are corrected, and after the ceiling wall cutting end mill 21 is accurately positioned, the tightening of the movement stop screw 8 and the rotation stop screw 10 is confirmed. .

Next, operate the handle 13 to operate the end mill 21 for ceiling wall cutting.
The bottom blade 20 'of this is lightly applied to the upper surface of the top wall 48 of the existing snow-melting nozzle 47, and in this state, the slide gauge 25 is moved up and down to set its zero point as a reference point (not shown). And then return the handle 13 to the bottom blade of the end mill 21.
20 'is separated from the ceiling wall 48 of the existing snow-melting nozzle 47, and in this separated state, the electric drill main body 17 is rotated and the handle 13 is operated to lower the end mill 21, and then the existing snow-melting nozzle is removed. The central portion of the ceiling wall 48 of 47 is cut into a circle with the old water spray holes 49 left. Whether or not this cutting has been sufficiently performed is confirmed by means of knowing that the depth of cutting has reached a predetermined dimension by looking at the descending amount of the slide head 14 on the scale of the slide gauge 25 that has been adjusted to zero.

After that, stop the electric drill body 17 and return it to the upper position, remove the ceiling wall cutting end mill 21 from the shank holder 19, and use the special pliers to remove the portion 50 enclosed by the circular cutting and the built-in object 51 such as the old valve. Remove it.

Further, a pilot hole drilling drill 22 is attached to the shank holder 19, and the pilot hole drilling drill 22 is rotated and lowered to drill a pilot hole 53 on the bottom surface of the case 52 of the existing snow-melting nozzle 47.

Next, the tap 23 is used to engrave the first female screw 54 in the prepared hole 53. In this engraving work, the tap 23 is rotated by using a built-in wrench 55 (not shown) for one-handed reverse rotation stopper and the short round bar pin 56 provided in advance on the wrench 55 is rotated to the shank holder 19. Fits freely to prevent head shake.

After that, tap 23 and wrench from shank holder 19.
55 is removed, the boring end mill 24 is attached to the shank holder 19, and the boring end mill 24 is used to cut off a portion such as the ceiling wall including the old water spray holes 49 in the existing snow removal nozzle 47.

In this way, the processing for the existing snow removal nozzle 47 is completed.

Next, the new built-in valve etc. 45 is inserted into the space 57 formed by removing the old built-in valve 51, and the second male screw 36 is screwed into the first female screw 54. Lid 33
The outer peripheral surface of the above and the cutting edge surface 58 of the hole formed by cutting by the boring end mill 24 are opposed to each other, and the opposed surfaces are made airtight by the O-ring 31, and then the case 52 of the existing snow removal nozzle 47. The upper surface of and the upper surface of the built-in object 45 such as a new valve are ground to the same height with a sander, and the work is completed.

(Operation) Since the present invention is as described above, the height of the movable hole 44 for water guiding and the fixed hole for water guiding are added by raising or lowering the water control piece 43.
When the height of 39 is the same, when the same water control piece 43 is twisted at a slight angle and the movable hole 44 for water guiding and the fixed 39 for water guiding do not overlap, obtain a fully closed state. In addition, it is possible to obtain a fully opened state when the positions are matched, and it is possible to obtain a partially opened state when the positions are overlapped by half. In addition, a movable hole for water transmission 44
The opening degree of partial opening can be finely adjusted according to changes in water pressure by increasing or decreasing the above-mentioned weight degree of a part of the water guide fixing hole 39.

Strictly speaking, the water control piece 43 slightly moves up and down due to the inclination of the third female screw 37 and the third male screw 41 in the fully open / closed operation and in the partially opened / closed operation. However, the vertical amount is extremely small.

(Effect of the Invention) In the nozzle device according to the present invention, since the lid body and the tube body are separate bodies as described above, when the lid body is damaged (damaged), it is sufficient to replace only the lid body and It is economical because there is no need to replace the whole, and since the lower end of the pipe is screwed to the case, the center of the top wall of the lid does not float due to internal pressure, There is no danger of leaking out, it is easy to process because the screw on the outer peripheral surface of the lid is not screwed, and the water control top can be arbitrarily moved up and down, so for example for water transfer This has a practical effect that it can be used in such a way that it can be opened and closed while the movable water guiding hole 44 is displaced upward by the radial dimension with respect to the fixed hole.
