[0014] (III) Beneficial Effects

[0015] This utility model provides an integrated auxiliary steam pressure reducing mixer, which has the following beneficial effects:

[0016] 1. This integrated auxiliary steam pressure reducing mixer, through the setting of the adjustment mechanism, allows for precise control of the amount of auxiliary steam entering the device by rotating the handle during use. The rotation of the handle drives the rotating rod to rotate, which in turn drives the rotating plate to rotate. This allows for adjustment of the opening and closing degree between the rotating plate and the auxiliary steam inlet pipe, thereby enabling precise control of the amount of auxiliary steam entering the device to meet the working pressure requirements of downstream equipment and prevent damage to the equipment due to excessive pressure.

[0017] 2. This integrated auxiliary steam pressure reducing mixer, through the setting of the Venturi mechanism, allows water and steam to enter the inside of the throat through the Venturi inlet pipe during use. At this time, because the throat is narrow, the amount of water and steam does not change, thereby increasing the flow rate of water and steam, so that water and steam mix inside the throat. The mixed water enters the diffuser, which can further improve the mixing uniformity of secondary steam, thereby improving the operating efficiency and stability of the equipment.
