[0016] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] refer to Figure 1-2 A high-efficiency atomizing temperature-reducing and pressure-reducing valve comprises a sleeve 1, which is installed at the low-pressure outlet pipe of the pressure reducer. After the high-pressure water vapor is depressurized by the pressure reducer, it is cooled by the temperature-reducing component in the sleeve 1. The above-mentioned pressure reducer is a prior art and does not need to be drawn or described in detail here.

[0018] refer to Figure 1-3 The cooling component in the sleeve 1 includes a support frame 2, a support tube 22 and a symmetrically arranged water spray frame 3.

[0019] refer to Figure 1-3 The upper surface of the sleeve 1 is fixedly mounted with a heat insulating pad 11, and the upper surface of the heat insulating pad 11 is fixedly mounted with a support platform 12. The support tube 22 penetrates the sleeve 1, the pad 11 and the support platform 12 and rotates together. The support tube 22 is fixedly arranged on the upper end surface of the support frame 2 and communicates with the interior of the support frame 2. The upper end is in a closed state. refer to Figure 1-3 A motor 13 is fixedly installed on the upper surface of the insulation pad 11 near the support tube 22, and a gear 14 is fixedly installed on the surface of the output shaft of the motor 13 and the surface of the support tube 22, and the two gears 14 are meshed with each other, wherein the insulation pad 11 can prevent the sleeve 1 through which high-temperature steam passes from affecting the operation of the motor 13.

[0020] Specifically, the motor 13 drives the gear 14 to rotate, thereby driving the support tube 22 to rotate, so that the cooling component in the sleeve 1 can be adjusted in angle, which can reduce the influence of its own structure on the flow velocity of water vapor in the sleeve 1.

[0021] refer to Figure 2-3 A T-shaped slide groove 21 with two sides being transparent is opened in the support frame 2, and two water spray frames 3 are symmetrically slidably installed in the T-shaped slide groove 21. Slide blocks 31 are symmetrically fixedly arranged on both sides of the lower end of the water spray frame 3. The slide blocks 31 slide in the T-shaped slide groove 21, and the slide blocks 31 ensure the sliding stability of the water spray frame 3 in the support frame 2.

[0022] refer to Figure 8 , grooves 211 are symmetrically provided on both sides of the support frame 2 , and a sealing sheet 8 for limiting the slider 31 is fixedly installed in the groove 211 by bolts. The sealing sheet 8 is for preventing the water spray frame 3 from sliding off the support frame 2 .

[0023] refer to Figure 2A support plate 5 fixed to the inner bottom surface of the middle part of the T-shaped slide groove 21 is arranged between the two water spray frames 3, and a spring 2 51 is fixedly connected between the support plate 5 and the water spray frame 3, and the spring 2 51 is used to help the water spray frames 3 on both sides to reset after moving.

[0024] refer to Figure 4-7 A plurality of rows of through holes 331 are provided on the outer surface of the water spray frame 3, and the number of through holes 331 in each row can be reduced accordingly with the inclined surface of the trapezoidal water spray frame 3. An atomizing nozzle 33 is fixedly installed in the through hole 331, and a cavity 32 communicating with the through hole 331 is provided in the water spray frame 3.

[0025] Specifically, by controlling the distance of the mobile water spray frame 3 in the support frame 2, the number of the atomizing nozzles 33 exposed outside the support frame 2 is controlled, so that the cooling effect of the atomizing nozzles 33 on the high-temperature water vapor can be adjusted.

[0026] refer to Figure 4-7 A circular baffle 6 is arranged on the outer side of the through hole 331, and the circular baffle 6 can close the through hole 331, and a rubber column 62 is fixedly arranged on the inner surface of the baffle 6, and the rubber column 62 corresponds to the nozzle of the atomizing nozzle 33, and a spring 332 is fixedly connected between the baffle 6 and the atomizing nozzle 33 for resetting the baffle 6.

[0027] refer to Figure 4-7 A second slide groove 333 is symmetrically provided on the inner wall of the through hole 331 at a position away from the atomizing nozzle 33, and an L-shaped connecting rod 61 is symmetrically fixedly provided on the inner surface of the baffle 6. A part of the L-shaped connecting rod 61 slides in the second slide groove 333, and the other part slides on the inner wall of the through hole 331, so as to prevent the water pressure sprayed by the atomizing nozzle 33 from being too high, resulting in the separation of the baffle 6 and the atomizing nozzle 33.

[0028] Specifically, when the warm water for cooling enters the cavity 32 in a high-pressure state, the baffle 6 inside the support frame 2 is blocked by the inner wall of the support frame 2, and the rubber column 62 will block the atomizing nozzle 33, and then the baffle 6 exposed on the outside of the support frame 2 will be flushed out by the cooling mist sprayed by the atomizing nozzle 33. At this time, the cooling mist passes through the through hole 331 connected to the outside, and then combines with the high-temperature water vapor to achieve the purpose of cooling. As the number of baffles 6 exposed on the outside of the support frame 2 increases, the number of atomizing nozzles 33 increases, the spraying range increases, and the cooling effect is enhanced.

[0029] Furthermore, the pressure reducer can adjust the high-pressure steam to below the set pressure to protect the equipment and pipelines from excessive steam pressure, and can be adjusted to a variety of different pressure values ​​as needed. In this embodiment, the water vapor at different pressures can be cooled by changing the moving distance of the water spray frame 3.

[0030] refer to Figure 4-7 A soft water inlet pipe 14 communicating with the cavity 32 is fixedly provided on the outer inclined surface of the water spray frame 3. The two water inlet pipes 14 are located in the support tube 22, and the upper ends pass through the upper end surface of the support tube 22 to be connected to the external high-pressure water inlet device. The high-pressure water inlet device is a prior art and does not need to be described and drawn in detail here.

[0031] refer to Figure 4-7 A T-shaped support rod 7 is arranged between the two water spray frames 3, the upper end of the T-shaped support rod 7 is arranged in the support tube 22, and the lower end cross bar is arranged in the support frame 2, and rollers 72 are symmetrically arranged on both sides of the lower end cross bar of the T-shaped support rod 7 for rotation. The rollers 72 are in contact with the inclined surface of the trapezoidal support frame 2. By lifting the T-shaped support rod 7, the rollers 72 push the water spray frames 3 on both sides, thereby driving the water spray frames 3 to slide in the support frame 2.

[0032] refer to Figure 1-4 A support platform 12 is fixedly installed on the upper surface of the insulation pad 11, and the upper end of the support tube 22 passes through the upper surface of the support platform 12 and rotates together. An electric telescopic rod 121 is fixedly arranged on the upper end surface of the support tube 22, and a connecting rod 71 is fixedly arranged on the upper end of the T-shaped support rod 7. The connecting rod 71 passes through the upper end surface of the support tube 22 and slides together. The upper end of the connecting rod 71 is fixed to the upper end of the piston rod of the electric telescopic rod 121 through a connecting plate. By starting the electric telescopic rod 121, the T-shaped support rod 7 is driven to rise and fall, thereby pushing the water spray frames 3 on both sides.

[0033] Furthermore, when the cooling component is not working, the water spray frame 3 can be retracted into the support frame 2 to prevent the atomizing nozzle 33 from being in contact with high-temperature water vapor for a long time and reducing its service life. At this time, the support frame 2 can adjust the angle by rotating the support tube 22 so that the side of the support frame 2 with a smaller width faces the flow position of the water vapor, thereby reducing the influence of the support frame 2 on the flow rate of the water vapor.
