Abstract
The utility model discloses a volute type swirl flow spray head, which comprises a spray head body, a suction inlet and a water sprinkling disk, wherein the spray head body consists of a volute cavity segment and a spout segment which are in threaded connection with each other; the spray head body is made of a nonmetallic material, thereby achieving high corrosion resistance when the spray head runs in the damp and hot environment of a cooling tower for a long time; reinforcing ribs are uniformly arranged on the outer surface of the volute cavity segment; the inner surface of the volute cavity segment is provided with an annular diversion trench; the suction inlet is positioned at the upper end of the volute cavity segment, and is a tangential horizontal suction inlet through which pressure water enter a volute cavity; the water sprinkling disk is connected with the spout segment through connecting rods; the spout segment, the connecting rods and the water sprinkling disk are integrated together; the water sprinkling disk comprises water splashing bars positioned inside the circular ring of the water sprinkling disk, and water plashing blades positioned outside the circular ring of the water sprinkling disk. The volute type swirl flow spray head has the characteristics of large jet range, wear resistance and capability of greatly enhancing the cooling effect of the cooling tower.
Description
Technical field
The utility model relates to cooling tower spray head field, particularly a kind of scroll casing type swirl flow nozzle.
Background technology
Fluid jetting head is that the liquid of certain pressure forms tiny liquid grain after shower nozzle.Existing fluid injector is by valve body, enters fluid passage, and spray orifice composition, controls flow and the nozzle pressure of liquid by the opening and closing of spool and valve body.The fluid injector of this structure, owing to can only realizing liquid from the ejection of Nozzle straight line, spray regime is little, and spary is inhomogeneous, atomization of liquid weak effect.In cooling tower, fluid jetting head is very important parts, and the quality of its spray effect directly affects the cooling effectiveness of cooling tower, and the material of shower nozzle selects, and directly affects the service life of shower nozzle.
Utility model content
The utility model has been designed and developed a kind of scroll casing type swirl flow nozzle, has spray regime large, water-fast washing away, and water pressure resistance fluctuates, and can significantly improve the scroll casing type swirl flow nozzle of the cooling effect of cooling tower.
The technical scheme that the utility model provides is:
A scroll casing type swirl flow nozzle, comprising:
Head body, it is comprised of spiral case cavity section and spout section, described spiral case cavity section and spout section are threaded connection, guarantee bonding strength, described head body is to be made by nonmetallic materials, on the outer surface of described spiral case cavity section, be evenly provided with reinforcement, wherein, on the inner surface of described spiral case cavity section, be provided with annular diversion trench;
Suction inlet, described suction inlet is positioned at the upper end of described spiral case cavity section, is tangential horizontal suction inlet, and press water enters in spiral case cavity along described tangential horizontal suction inlet;
Water dispersing disc, it links together by connecting rod and described spout section, the upper end of described connecting rod is connected with spout section, the lower end of described connecting rod is connected with water dispersing disc, described spout section, connecting rod and water dispersing disc are structure as a whole, and described water dispersing disc comprises dabble bar and the blade that dabbles that is positioned at water dispersing disc annulus outside that is positioned at water dispersing disc annulus the inside;
Preferably, described suction inlet is external screw thread mouth.
Preferably, described head body is to be made by ceramic material.
Preferably, described in be positioned at water dispersing disc annulus the inside the bar that dabbles be petal shape, on each petal, be provided with guiding gutter, space leaks between every two petals.
Preferably, the quantity of described connecting rod is 3.
Scroll casing type swirl flow nozzle described in the utility model, head body is used ceramic wear-resisting material to make, and anti-wear performance is strong, corrosion-resistant, good antiscale property.Described spiral case cavity section and spout section are threaded connection, and have guaranteed bonding strength, make it tolerate powerful surge.Because spiral case inside does not arrange rotation spray core, can effectively avoid the clogging of shower nozzle.Because spiral case outer setting has reinforcement, can strengthen the intensity of spiral case, the effect in extension device service life.The bar that dabbles that is positioned at water dispersing disc annulus the inside is petal shape, on each petal, be provided with guiding gutter, space leaks between every two petals, when the umbrella rotation water body from shower nozzle ejection, after impacting on the bar that dabbles of petal shape, form vaporific fine liquid particles, and fine liquid particles is evenly distributed, increased frigorimeter area, thereby can improve splash uniformity and spray effect, the cooling effectiveness of cooling tower is improved.Spiral case cavity section and spout section adopt and are threaded, and make structure more reliable, use safer.Water dispersing disc and spout section are structure as a whole, and have reduced connecting portion, and shower nozzle intensity is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of scroll casing type swirl flow nozzle described in the utility model.
Fig. 2 is the top view of scroll casing type swirl flow nozzle described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, to make those skilled in the art can implement according to this with reference to description word.
As shown in Figure 1, the utility model provides a kind of scroll casing type swirl flow nozzle, comprising:
Head body 1, it is comprised of spiral case cavity section 2 and spout section 3, and described spiral case cavity section and spout section are threaded connection,, head body is used ceramic wear-resisting material to make, and anti-wear performance is strong, corrosion-resistant, good antiscale property.On the outer surface of described spiral case cavity section, be evenly provided with reinforcement, wherein, on the inner surface of described spiral case cavity section, be provided with annular diversion trench;
Water dispersing disc 5, it links together by connecting rod 6 and described spout section, the upper end of described connecting rod is connected with spout section, the lower end of described connecting rod is connected with water dispersing disc, described spout section, connecting rod and water dispersing disc are structure as a whole, described water dispersing disc comprises dabble bar and the blade 7 that dabbles that is positioned at water dispersing disc annulus outside that is positioned at water dispersing disc annulus the inside, as shown in Figure 2;
