Abstract
The utility model discloses a kind of modified workshop section water spray tank nozzle, comprise nozzle body and be arranged on the metal derby above this nozzle body, be provided with water spray aperture at described nozzle body top, below described metal derby, be provided with paxilla and this paxilla is positioned at directly over described water spray aperture; It is characterized in that: be provided with boss in described paxilla bottom, between the inner face and outer face of this boss, be provided with the transition cambered surface of 90 ° and the radius of this transition cambered surface is 0.9-1.1 millimeter.Modified workshop section of the present utility model water spray tank nozzle can reduce the wearing and tearing of paxilla bottom surface, thus extends the service life of the utility model shower nozzle.
Description
Technical field
The utility model relates to a kind of water spray tank nozzle, particularly relates to a kind of modified workshop section water spray tank nozzle.
Background technology
Fig. 1 is the structural representation of prior art shower nozzle, the metal materials such as shower nozzle many employings stainless steel (316L) of existing conversion section water spray tank, shower nozzle generally comprises nozzle body 1 and metal derby 3, paxilla 2 is provided with below metal derby 3, wherein, nozzle body 1 top is provided with water spray aperture 11.Its workflow is: water pipe is connected to the bottom of nozzle body 1, water under high pressure from bottom to top runs from the circular hole 12 of nozzle body 1 inside, when it walks to topmost, arrive water spray aperture 11, its aperture is approximately 3mm, now water velocity increases, water bundle attenuates, from water spray aperture 11, impinge upon diameter after injection be about 3.84mm, be highly 3.34mm metal derby 3 on, then water Shu Si scatters, form spray form, contact after damaging with friendship again, one can lower the temperature, two can be changed into steam after participate in exchange reaction, but, owing to being worn very easily at work with the side that the paxilla 2 that water directly contacts contacts with high pressure high flow rate flow velocity water bundle, after wearing and tearing, this face just there will be rough place, like this after above water bundle is got to again, would not all evenly in aerosolize, but have small part to be that drop occurs.But drop will form current in continuous operation, these tiny current are not easily transformed gas and are vaporized into steam, will take stove of exchanging to form of liquid water, and aqueous water can make loss on transmission catalyst lump, poisoning, inefficacy, shortens the service life of catalyst.So not only cause replacing catalyst how expensive, also therefore can stop morely, thus bring certain loss.
Utility model content
The purpose of this utility model is to provide a kind of modified workshop section water spray tank nozzle, and this modified workshop section water spray tank nozzle can reduce the wearing and tearing of paxilla bottom surface, thus extends the service life of the utility model shower nozzle.
For achieving the above object, the utility model provides a kind of modified workshop section water spray tank nozzle, comprise nozzle body and be arranged on the metal derby above this nozzle body, be provided with water spray aperture at described nozzle body top, below described metal derby, be provided with paxilla and this paxilla is positioned at directly over described water spray aperture; Be provided with boss in described paxilla bottom, between the inner face and outer face of this boss, be provided with the transition cambered surface of 90 ° and the radius of this transition cambered surface is 0.9-1.1 millimeter.
The radius of described transition cambered surface is 1 millimeter, and described metal derby is piece of stainless steel, and described water spray aperture is circular water spray aperture, and described paxilla is circular paxilla.
Described paxilla is made up of carbofrax material, and the inner hollow out of described metal derby, described cylinder fritter is arranged in the hollow out position of metal derby and this paxilla bottom and reaches below metal derby.
The utility model, by being provided with boss in described paxilla bottom, is provided with the transition cambered surface of 90 ° and the radius of this transition cambered surface is 0.9-1.1 millimeter between the inner face and outer face of this boss.Like this after water bundle lining is on paxilla, its edge no longer includes the corner angle as the paxilla of traditional sprinkler heads, namely the wearing and tearing of paxilla bottom surface can be reduced, thus the uneven problem not only avoided paxilla bottom surface to be worn and cause and extend service life of the utility model shower nozzle, thus the catalyst replacement cycle of whole conversion is extended.In addition, paxilla also can be made to be made up of carbofrax material, thus strengthen scuff resistance, paxilla bottom surface is more not easily worn.
By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art shower nozzle;
Fig. 2 is the structural representation of embodiment one;
Fig. 3 is the structural representation of embodiment two.
Detailed description of the invention
With reference now to accompanying drawing, describe embodiment of the present utility model, element numbers similar in accompanying drawing represents similar element.
Embodiment one:
Please refer to Fig. 2, a kind of modified workshop section water spray tank nozzle, the metal derby 3 comprising nozzle body 1 and be arranged on above this nozzle body 1, be provided with water spray aperture 11 at described nozzle body 1 top, below described metal derby 3, be provided with paxilla 2 and this paxilla 2 is positioned at directly over described water spray aperture 11; Be provided with boss 21 in described paxilla 2 bottom, between the inner face and outer face of this boss 21, be provided with the transition cambered surface of 90 ° and the radius of this transition cambered surface is 0.9-1.1 millimeter, as described in the radius of transition cambered surface be 1 millimeter.Wherein, described metal derby 3 can be piece of stainless steel, and described water spray aperture 11 can be circular water spray aperture, and described paxilla 2 can be circular paxilla.
Embodiment two:
The difference of the present embodiment and embodiment one is: please refer to Fig. 3, described paxilla 2 can be made up of carbofrax material, the inner hollow out of described metal derby 3, described cylinder fritter 2 is arranged in the hollow out position of metal derby 3 and this paxilla 2 bottom and reaches below metal derby 3.
More than in conjunction with most preferred embodiment, the utility model is described, but the utility model is not limited to the embodiment of above announcement, and should contain various carry out according to essence of the present utility model amendment, equivalent combinations.
