Background
As shown in figure 1, in the existing high-temperature and high-pressure steam temperature reduction process, before the temperature reduction water is sprayed into a nozzle through a 90-degree angle type runner, the existing sleeve is only provided with a single-hole inlet, flow equalization treatment is not carried out, high-pressure difference temperature reduction water is sprayed into a nozzle cavity at a high speed, so that the temperature reduction water is sprayed into the runner to cause local blow-off, temperature non-uniform transformation, and water drops at relatively low temperature can cause hardenability damage to a chromium-molybdenum steel temperature reduction water pipeline, so that the pipeline has cracks, the wall thickness is reduced, and the like, and potential safety hazards are very large.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: in order to solve the problems that the existing sleeve only has a single-hole inlet and is not subjected to flow equalization treatment, high-pressure-difference temperature-reducing water is sprayed into a nozzle cavity at a high speed, so that the temperature-reducing water is sprayed into a runner to cause a local partial blowing phenomenon, the temperature is non-uniformly changed, and relatively low-temperature water drops can cause hardenability damage to a chromium-molybdenum steel temperature-reducing water pipeline, so that the pipeline has risks of cracking, wall thickness reduction and the like, and the potential safety hazard is very large, the flow equalization sleeve and the nozzle for the porous hedging inlet of the temperature-reducing water are provided.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a sleeve flow equalizes for porous hedging import of desuperheating water, includes the body, water channel has been seted up to the one end of body, seted up a plurality of groups of inlet opening on the outer peripheral face of body, a plurality of groups the inlet opening sets up and communicates each other around water channel, a plurality of two liang of relative settings of inlet opening.
According to the utility model, the water inlets are oppositely arranged on the body, and the opposite water inlets are utilized for carrying out temperature reduction water hedging, so that the flow velocity is reduced, the water spraying and flow equalizing treatment is realized, the blow-off phenomenon of the nozzle cavity is avoided, the temperature is more uniform, the hardenability damage and the wall thickness reduction of the local chromium molybdenum steel temperature reduction water pipeline can not occur, and the safety is greatly improved.
In order to prevent the body from being installed into the nozzle, one end of the water inlet hole in the body is not in a gap with the nozzle, so that water cannot enter the body.
Furthermore, the water inlet hole is provided with a plurality of along the axial of the water outlet.
A nozzle is provided with the flow equalizing sleeve for the porous hedging inlet of the temperature reduction water.
The utility model has the beneficial effects that: when the flow equalizing sleeve and the nozzle for the porous opposite-flushing inlet of the desuperheating water are used, the water inlets are oppositely arranged on the body, and the desuperheating water is flushed by using the opposite water inlets, so that the flow speed is reduced, the water spraying flow equalizing treatment is realized, the blow-off phenomenon of a nozzle cavity is avoided, the temperature is more uniform, the hardenability damage and the wall thickness reduction of a local chromium-molybdenum steel desuperheating water pipeline cannot occur, and the safety is greatly improved.
