Description
Technical field
The utility model relates to a kind of atomizing sprayer, specifically be a kind of spray spout.
Background technology
At present, at the spray spout (as the cooling water nozzle) that use in fields such as high temperature cooling, humidification, machine tool lubrication oil spray system, generally be to contain the plain nozzle of opening an aperture on an internal cavity, the nozzle head in the inside of nozzle body.As the water storage zone, the pressure that depending nozzle head aperture forms produces and sprays this nozzle with the internal cavity of nozzle body.Its shortcoming is: the water in this nozzle is extruded, and current are not gone out through nozzle body inner cavity body swirl injection, so its spray pressure is little, range of jet is nearer, and runner has some setbacks, and water smoke is inhomogeneous, and water consumption is serious, and service life is short.A kind of spray spout is disclosed on the China national intellectual property board web, its intake tunnel, internal cavity and exhalant canal are point-blank, internal cavity is provided with the X-shaped spinning disk, apopore is taper, and this spray spout has overcome above shortcoming to a certain extent, but the current of this nozzle have increased certain resistance in passage, when adopting this nozzle, recirculated water need pass through the booster pump supercharging, and himself no function of increasing pressure, this has objectively increased equipment cost and energy consumption.
The utility model content
The technical problems to be solved in the utility model is, provide a kind of current little at the passage internal resistance, do not need booster pump, spray pressure is big, range of jet is far away, easily forms the spray spout of atomizing effect and energy-saving and water-saving.
Technical solution of the present utility model is, a kind of spray spout is provided, comprise nozzle body that is provided with water inlet pipe interface, inlet opening, internal cavity and the nozzle head that is provided with apopore, described inlet opening, internal cavity and apopore three communicate, and described apopore is outer little interior big bellmouth; Described internal cavity is circular, described circular internal cavity and taper apopore coaxial line, the axis normal of the axis of described inlet opening and circular internal cavity and apopore, described inlet opening is provided with the little taper of outer imperial palace, the vertical centre line parallel of the axis of described inlet opening and internal cavity, and the distance of the vertical center line of the axis of inlet opening and circular internal cavity less than the radius of circular internal cavity greater than 1/2 of circular internal cavity radius.
After adopting above structure, the utility model spray spout compared with prior art has the following advantages:
Because the inlet opening of nozzle body is provided with the little bellmouth of outer imperial palace, when current enter the taper inlet opening, the flow of water from large to small, the pressure of water changes from small to big, thus the current of formation high speed and high pressure.Simultaneously, because the axis of inlet opening and the axis normal of circular internal cavity and apopore, the vertical centre line parallel of the axis of inlet opening and internal cavity, and the distance of the axis of inlet opening and the vertical center line of circular internal cavity less than the radius of circular internal cavity greater than 1/2 of circular internal cavity radius, generally, be that the inlet opening is connected with internal cavity is eccentric, make the inlet opening become an eccentric orfice, like this, the high speed and high pressure current that form through the taper inlet opening just form screw type eddy current form along the inwall of internal cavity, taper apopore along nozzle head ejects (same again, when current enter the taper apopore, the flow of water from large to small, the pressure of water changes from small to big, and forms the current of high speed and high pressure).In sum, the utility model spray spout current are little at the passage internal resistance, do not need booster pump, and can form at a high speed, evenly, the spray effect of atomizing, its spray pressure is big, range of jet is far away, and because the effect of water smoke, reduce the inhomogeneities of current, both saved equipment cost and energy consumption, saved water resource again.
As improvement, the central authorities of the circular internal cavity of described nozzle body, be provided with a cylindrical boss with circular internal cavity coaxial line, like this, make screw type eddy current present stable laminar condition, reduced the collision between current, made that the current in the internal cavity keep established high-speed eddy, make at a high speed, evenly, the spray effect of atomizing is better.
As further improvement, described nozzle head and described nozzle body are for being threaded more convenient installation and maintenance.
As further improving, be provided with sealing ring at nozzle head on the end face with combining of nozzle body junction, leak to avoid joint, thereby keep high-voltage high-speed and further conserve water resource.

Fig. 1 is the cross-sectional view of facing of the present utility model.
Fig. 2 is that the utility model is looked partial cutaway schematic on the right side of twisting lost nozzle head rear nozzle body.
Shown in the figure 1, nozzle body; 2, cylindrical boss; 3, nozzle head; 4, apopore; 5, sealing ring; 6, circular internal cavity; 7, inlet opening.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2.
The utility model spray spout comprises nozzle body 1 that is provided with water inlet pipe interface, inlet opening 7 and internal cavity and the nozzle head 3 that is provided with apopore 4.Described inlet opening 7, internal cavity and apopore 4 threes communicate.Described apopore 4 is interior big outer little bellmouth.
Characteristics of the present utility model are, described internal cavity is circular, described circular internal cavity 6 and taper apopore 4 coaxial lines, the axis normal of the axis of described inlet opening 7 and circular internal cavity 6 and apopore 4, described inlet opening 7 is provided with the little taper of outer imperial palace, promptly the inlet opening 7 interior one section be the little taper of outer imperial palace.The vertical centre line parallel of the axis of described inlet opening 7 and internal cavity 6, and the distance of the vertical center line of the axis of inlet opening 7 and circular internal cavity 6 less than the radius of circular internal cavity 6 greater than 1/2 of circular internal cavity 6 radiuses.Described water inlet pipe interface refers to internal thread interface, and internal thread (not marking among the figure) is located on the hole wall of inlet opening 7 inducers.The central authorities of the circular internal cavity 6 of described nozzle body 1, be provided with a cylindrical boss 2 with circular internal cavity 6 coaxial lines, according to general knowledge as can be known, the length of the cylindrical boss 2 left inwall (shown in Figure 1) of being longer than circular internal cavity 6 to inlet opening 7 away from the length between the tube wall of the left inwall of circular internal cavity 6.Described nozzle head 3 and described nozzle body 1 are for being threaded.Be provided with sealing ring 5 at nozzle head 3 on the end face with combining of nozzle body 1 junction.
The utility model not only limits to above embodiment, and its concrete structure allows variation, as: described water inlet pipe interface also can be external screw thread interface or inside and outside splicing interface (can stick with glue and connect); The central authorities of the circular internal cavity 6 of nozzle body 1 also can not establish cylindrical boss 2; Described nozzle head 3 also can be an integral body with described nozzle body 1; It is the little taper of outer imperial palace that the taper that the outer imperial palace that described inlet opening 7 is provided with is little also can be inlet opening 7 total lengths; Or the like.In a word, all various variations of being done in the independent claims scope are all in protection domain of the present utility model.
