Description
Technical field
The present invention relates to a kind of shower nozzle for spraying or spraying, particularly a kind of shower nozzle that can spray or spray solid, powdery thing and liquid dope.
Background technology
The ejiction opening of existing shower nozzle is mostly cylindrical, and when spraying or spraying, ejiction opening is circular injection or circular sprinkling, easily produces wheat circle effect, makes the destination being sprayed onto leave dead angle, and the scope of spraying or spraying is subject to certain restrictions.When being applied to the occasions such as depot fire-fighting, field irrigation, mortar mud foreign material body or thickness object often can stop up ejiction opening, and causing cannot operation, even can cause danger.
Summary of the invention
The object of the invention is to provide a kind of trapezoidal shower nozzle, solve the problem of the easy obstruction of ejiction opening and injection or spraying range.
According to an aspect of the present invention, provide trapezoidal shower nozzle, by spiral bar and pipe joint, connected as one and the two is longitudinally connected by through hole, the longitudinal section of through hole is trapezoidal, and the inwall of through hole is plane, and the outer surface of spiral bar is also plane.
Its beneficial effect is: because the ejiction opening of trapezoidal shower nozzle is formed by the gap between every layer of spiral bar, this ejiction opening is communicated with through hole again, ejecta injects from the throughhole portions of pipe joint so, and enter ejiction opening through the throughhole portions of spiral bar, by ejiction opening, spray or spray, the opening of ejiction opening is consistent with the spiralling track of spiral bar, thereby guaranteed larger ejection area, therefore can realize when spraying or spraying solid, powdery thing and liquid dope and can not stop up ejiction opening.Because the inside and outside surface of spiral bar is plane, between every layer of spiral bar, form polyhedron-shaped ejiction opening, and the length of ejiction opening is consistent with the spiralling track of spiral bar, thereby guaranteed larger ejection scope, especially, the longitudinal section of through hole is trapezoidal, and the inwall of through hole is plane, making the ejecta stress surface injecting from pipe joint is plane, injection or sprinkling power have been increased, therefore can realize ejecta is polyhedron-shaped even injection or sprinkling, and ejection scope greatly, is not stayed dead angle.
In some embodiments, the angle of spiral bar and its axis is 20 °～180 °.Its beneficial effect is: due to the variation of angle between spiral bar and axis, therefore can realize the difference of injection or spray angle, thereby guarantee larger ejection scope.
In some embodiments, between every layer of spiral bar, be spiral abreast.Its beneficial effect is: due between every layer of spiral bar for parallel, and between every layer equidistantly or not equidistant, therefore can realize even injection or the sprinkling that ejecta is regular polygon shape.
In some embodiments, the outline of the longitudinal section of spiral bar can be trapezoidal, rectangle or square.Its beneficial effect is: due to the vertical sectional shape of spiral bar, determined the outer contour shape of spiral bar, therefore can realize different ejection shapes to be applicable to different places.
In some embodiments, the longitudinal section of the inwall of through hole is trapezoidal, rectangle or square.Its beneficial effect is: due to the difference of the flat shape of through-hole wall, therefore can realize the difference of the ejection power of injecting through hole ejecta.
In some embodiments, the helix pitch of spiral bar is 1mm～100mm.Its beneficial effect is: due to the variation of spiral bar pitch, and pitch can, for equidistantly, also can, for not equidistant, therefore can realize the different size of dehiscing of ejiction opening.
In some embodiments, the number of plies of spiral bar is 2～10 layers.Its beneficial effect is: the multi-layer helical rising due to spiral bar, therefore can realize stereo-spray or sprinkling multistage, multi-angle.
In some embodiments, the top of spiral bar is provided with spray tank.Its beneficial effect is: because spray tank can be cross recess or multi-groove structure, therefore can realize injection or the sprinkling at trapezoidal shower nozzle top, make ejecta more even, further increase ejection scope.
In some embodiments, the both sides at spiral bar top are respectively equipped with opening, and the angle of two openings is 10 °～120 °.Its beneficial effect is: due to the variation of angle between the both-side opening at spiral bar top, therefore can realize the different ejection angle in both sides at spiral bar top.
In some embodiments, the top of spiral bar is provided with variation step, and the angle that changes step and spiral bar axis is 10 °～40 °.Its beneficial effect is: owing to changing the setting of step, therefore can realize even injection or the sprinkling at the top of spiral bar.
In some embodiments, the number of plies of spiral bar is 2～10 layers.Its beneficial effect is: the multi-layer helical rising due to spiral bar, therefore can realize stereo-spray or sprinkling multistage, multi-angle.
The present invention is simple in structure, and at field irrigation Shi Kepen farmers' liquid fertilizer, can large area when fire-fighting fire extinguishing dust shape and liquid dope, can reach even extinguishing ability, and blow-off velocity is fast, ejection power is strong, can not stop up ejiction opening.
