全に微粒化された冷却氷粒が得られることが解った。As shown in FIG. 2, the axes of the cooling water jetting nozzle 6 and the atomizing steam jetting nozzle 9 intersect with each other on the outlet side, and the width of the cooling water jetting nozzle 6 is the width of the A11 jetting steam jetting nozzle 9.

The positions of the nozzle 6 and the above-mentioned spray steam ejection nozzle 9 are as follows:
Since these jet nozzles 6.9 are located in the same radiation plane, and the directions of the fluxes of these jet nozzles 6.9 cross each other (orthogonal in this example), the atomizing effect of the high-speed steam jetted from the spray steam jet nozzle 9 is improved. As a result, the cooling water jetted from the cooling water jetting nozzle 6 becomes a very fine mist and is scattered into the mixing zone.

上記第１の実施例と実質的に同じである。FIG. 3 shows another embodiment of the steam conversion valve of the present invention, in which a Schilling-type valve body 11 is arranged on the outside of the cage-type valve body 2, and by sliding it in the axial direction. , the ports 2a of the valve body 1 are sequentially closed and closed, and the high-pressure, high-temperature steam is ejected from the outside of the valve body 2 to the inside while being throttled by the ports 2a, so the steam collides with each other. except that the pressure is reduced by
This is substantially the same as the first embodiment described above.

材料の熱応力を低減せしめることが出来る。(1) A part of the high-pressure steam is used to atomize the cooling water and mix it with the reduced-pressure steam from the port, which promotes heat exchange and improves the temperature reduction effect. Thermal stress can be reduced.

It can be made to squirt in a state where it is

度差が縮小する。(3) Since an annular cooling medium chamber is provided inscribed in the middle part of the valve body between the high pressure part and the pressure reducing part, part of the heat transferred from the valve body part of the high pressure part to the valve body part of the pressure reducing part is absorbed. The cooling water absorbs the material and lowers the average temperature of the constituent materials of the decompression section, and the cooling water itself is heated, reducing the temperature difference between the two that causes thermal shock fatigue.

Therefore, it is easy to control and no backflow water hammer occurs.
