Technical Field

[0001] The invention relates to the technical field of sleeves, and in particular to a sleeve with temperature-reducing water spray holes distributed in a sinusoidal curve. Background Art

[0002] In the existing high-temperature and high-pressure steam cooling process, most of the nozzles are single nozzles, and each nozzle sprays water from a single hole, resulting in poor atomization effect. This can easily cause hardenability damage to the chromium-molybdenum steel pipeline, causing cracks in the pipeline, thinning of the wall thickness, and other risks, posing a great safety hazard. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that in the existing high-temperature and high-pressure steam cooling process, most of the nozzles are single nozzles, each nozzle has a single hole to spray water, the atomization effect is not good, it is easy to cause hardenability damage to the chromium-molybdenum steel pipeline, causing cracks in the pipeline, thinning of the wall thickness and other risks, and the safety hazard is very large. Now a sleeve with a sinusoidally distributed cooling water spray hole is provided.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a sleeve with sinusoidally distributed cooling water spray holes, including a main body, one end of the main body is provided with a conveying channel, and the main body is provided with a plurality of water spray hole groups connected with the conveying channel, each group of the water spray hole groups is composed of a plurality of water spray holes, and the water spray holes in each group of the water spray hole groups are sinusoidally distributed.

[0005] The present invention arranges the water spray holes in the water spray hole group according to a sine curve, so that the water spray holes spray water continuously and the atomization effect is better. This can solve the influence of the interaction between high-temperature steam and high-pressure cooling water on the life of the nozzle in the existing steam cooling process, and can be widely promoted and applied to the cooling system of the steam pipeline network of power stations and power stations.

[0006] Since the sine curve is composed of at least one group of crest segments and one group of trough segments, in order to facilitate the manufacture of the water spray hole group, further, the water spray holes in each group of the water spray hole group form a sine curve consisting of at least two parts, the crest part and the trough part. A part of the water spray holes in the water spray hole group forms the crest part, and another part of the water spray holes forms the trough part, and the sine curve is formed by the above two parts.

[0007] Furthermore, the crest portion and the trough portion are centrally symmetrically arranged.

[0008] For the convenience of maintenance, further, a plurality of nozzles are detachably mounted on the body, and the water spray holes are arranged on the nozzles. By detachably mounting the nozzles on the body and providing the water spray holes on the nozzles, it is easier to perform later maintenance on the water spray holes.

[0009] Furthermore, a plurality of groups of water spray holes are arranged axially along the conveying channel.

[0010] The beneficial effects of the present invention are as follows: when the sleeve of the sinusoidally distributed cooling water spray holes of the present invention is in use, the water spray holes in the water spray hole group are arranged according to a sinusoidal curve, so that the water spray holes spray water continuously, and the atomization effect is better. This can solve the influence of the interaction between high-temperature steam and high-pressure cooling water on the nozzle life in the existing steam cooling process, and can be widely promoted and applied to the cooling system of the steam pipeline network of power stations and power stations, avoiding the problem that in the existing high-temperature and high-pressure steam cooling process, most of the nozzles are single nozzles, each nozzle has a single hole to spray water, the atomization effect is not good, and it is easy to cause hardenability damage to the chrome-molybdenum steel pipeline, causing cracks in the pipeline, thinning of the wall thickness and other risks, and a very large safety hazard.
