Cooling jacket 25 is set in installing, and the on both sides of the middle in cooling jacket 25 is respectively set partition 28 and is divided into cooling jacket up and down
The cyclic water channel for linking up circulating water cavity up and down is respectively set in two parts circulating water cavity, the divider ends of atomizer two sides
29, circulating water inlet 21 and recirculated water is respectively set in the end of the circulating water cavity up and down upper and lower close to the water inlet pipe 20
Resistance to material 26 is arranged in outlet pipe 27 between cooling jacket 25 and the outer tube 23, close to the recirculated water inlet tube and outlet tube
Sealing flange 22 is arranged in 23 end of outer tube.
As shown in Figure 3, Figure 4, the nozzle, including nozzle core 1 and nozzle housing 9, in cylinder barrel shaped nozzle housing 9 its
Top inner peripheral is linked together by internal screw thread 10 with the nozzle core 1 being fitted in nozzle housing, is set on nozzle housing outer wall
External screw thread 8 is set, to connect water inlet tube body.Be respectively set from top to bottom in nozzle housing bottom centre truncated cone-shaped cavity 6 with
And cylindrical hole for water spraying 7；Intake antrum, the lower part four of intake antrum is arranged in nozzle core top in the cylinder in T shape of nozzle core 1
Four water outlet circular holes 2 are set on peripheral wall, circle ring chamber 3 is constituted between nozzle core and nozzle housing, are discharged circular hole 2 and circle ring chamber
3 are connected.Water chamber 4 is set in nozzle core bottom, and mutually closing separates between water chamber 4 and the intake antrum.Water outlet
Four intake chambers are arranged in a pair two-by-two on the periphery wall of chamber 4, wherein there are two intake chambers 5 along the same radial cloth of water chamber
It sets, tangential direction mutually opposing arrangement of the another two rotation direction intake chamber 11 along water chamber, the bottom surface of nozzle core 1 and the circle
