Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Fig. 1 ~ 3, comprise flange 11, supporting pipeline 12, valve body 13, valve flowing channel 14, multiple flow passages flow ring 15, bolt hole 16, eccentric runner 21, venturi circular arc 22, metering orifice 23, corner cut 24 etc.
As shown in Fig. 1 ~ 3, a kind of multiple flow passages annular of the utility model product attemperator, comprise valve body 13, valve body 13 top socket joint groove is tightly connected supporting pipeline 12, supporting pipeline 12 upper end is fixedly connected with flange 11, valve body 13 radial direction is provided with valve flowing channel 14, described valve flowing channel 14 upper end is connected with supporting pipeline 12 endoporus, valve body 13 inner hollow position is provided with multiple flow passages flow ring 15, central axis and valve body 13 central axis of described multiple flow passages flow ring 15 coincide, multiple flow passages flow ring 15 cylindrical is provided with metering orifice 23, metering orifice 23 radial direction extends to the inner chamber that multiple flow passages flow ring 15 corresponds to corner cut 24 place, multiple flow passages flow ring 15 surface is provided with several eccentric runners 21, each eccentric runner 21 is connected with contiguous metering orifice 23 respectively, eccentric runner 21 upper end is communicated with valve flowing channel 14 lower end.
Multiple flow passages flow ring 15 entrance point is roughly in venturi circular arc 22 shape, and outlet side forms corner cut 24.
Supporting pipeline 12 upper end and flange 11 are welded to connect, and the faying face of supporting pipeline 12 lower end and valve body 13 is welded and fixed.
Metering orifice 23 has 8,8 metering orifices 23 are divided into two row, be arranged symmetrically in multiple flow passages flow ring 15 surface ringwise and correspond to corner cut 24 place, the flow of desuperheating water is accurately controlled by metering orifice 23, make desuperheating water 360 ° of full angles mix with superheated steam, the eccentric runner 21 corresponding to each metering orifice 23 place plays the effect making desuperheating water rotary-atomizing simultaneously.
The spacing at the center of valve flowing channel 14 and the center of valve body 13 is 5mm, and ensure the length of eccentric runner 21, valve body 13 is provided with bolt hole 16, makes this product only need less installing space just can meet when mounted install needs by bolt hole 16; By being welded to connect between supporting pipeline 12 and valve body 13.
The utility model product when mounted, is connected with the companion flange on superheated steam main pipeline by the bolt hole 16 on valve body 13.
During normal work, desuperheating water, by flange 11, flows through valve flowing channel 14, then enters metering orifice 23 by eccentric runner 21.
Eccentric runner 21 is desuperheating water rotary-atomizings, and metering orifice 23 controls the flow of desuperheating water.Superheated steam is through multiple flow passages flow ring 15, and venturi circular arc 22 bore reduces gradually, and superheated steam flow velocity is increased.Be 90 ° of corner cuts 24 through outlet side again, make superheated steam produce turbulent flow, and attemperation water flow hole 23 circular symmetric be arranged in 90 ° of corner cuts 24.Such desuperheating water and superheated steam will the mixing of 360 ° of full angles.
