Abstract
The utility model is a kind of steam support type steam converter valve, belongs to thermoelectricity, nuclear power valve field.Steam support type steam converter valve is made up of valve body, valve rod, flap, valve seat, steam support type nozzle, hydroecium, bonnet, desuperheat water pipe etc..Steam support type nozzle, which is installed in valve body, to be welded and fixed, and is coordinated with valve seat outside dimension and installed.During valve working, steam medium is realized from valve seat top by the throttling fit of flap and valve seat to depressurize, and desuperheating water flows into hydroecium through desuperheat water pipe and sprayed from desuperheating water spout, and desuperheat is carried out to the steam after decompression.Meanwhile introduce after fraction atomizing steam enters the space being separated out between steam support type nozzle and valve body, then ejection is converged at nozzle by nozzle and desuperheating water, play the effect of assisted atomization.
Description
Technical field
A kind of steam support type steam converter valve is the utility model is related to, belongs to thermoelectricity, nuclear power valve field.
Background technology
Steam support type steam converter valve is arranged on thermoelectricity, nuclear power generating sets steam-water pipe, is regulation steam pressure temperature
Visual plant.
For the steam converter valve of prior art due to the limitation of valve space, the desuperheating water atomizing effect that nozzle sprays is bad,
Cause temperature lowering effect bad.
Utility model content
The purpose of this utility model is to provide a kind of steam support type steam converter valve, improves desuperheating water atomizing effect.
The technical solution of the utility model is a kind of steam support type steam converter valve, and it, which includes major part, valve body
(1), valve seat (2), flap (3), valve rod (4), steam support type nozzle (5), hydroecium (6), bonnet (7), desuperheat water pipe (8) and master
Position is wanted to have steam nozzle (9), desuperheating water spout (10).Steam support type nozzle, which is installed in valve body, to be welded and fixed, and and valve
Seat outside dimension coordinates installation.Atomizing steam enters steam support type nozzle by valve seat side opening, then by steam nozzle with subtracting
Warm water converges in desuperheating water spout, and the energy of atomizing steam atomizes water into minimum water droplet and sprayed.
The beneficial effects of the utility model are：By support type nozzle arrangements, the steam of introducing is played assisted atomization and subtract
The effect of warm water, reach the purpose for improving desuperheat efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of steam support type steam converter valve；
Fig. 2 is the structural representation of steam support type nozzle；
In figure：1. valve body, 2. steam support type nozzles, 3. valve seats, 4. flaps, 5. valve rods, 6. bonnets, 7. hydroeciums, 8. subtract
Warm water tube and 9. steam nozzles, 10. desuperheating water spouts.
Embodiment
In the embodiment shown in fig. 1, steam support type nozzle, which is installed in valve body, is welded and fixed, and with valve seat outside dimension
Coordinate installation.During valve working, steam medium is realized from valve seat top by the throttling fit of flap and valve seat to depressurize, desuperheating water warp
Desuperheat water pipe flows into hydroecium and sprayed from desuperheating water spout, and desuperheat is carried out to the steam after decompression.Meanwhile introduce fraction atomization
After steam enters the space that is separated out between steam support type nozzle and valve body, then spray converged at nozzle by nozzle and desuperheating water
Go out, play the effect of assisted atomization.
Claims (2)
1. steam support type steam converter valve, it is characterised in that：It, which includes major part, valve body, valve seat, flap, valve rod, steaming
