Abstract
The utility model relates to a kind of shower nozzle with keying function, comprise valve body, spool, piston and push rod, described valve body is provided with inlet, liquid outlet and the import of control liquid, described push rod passes piston and is together arranged in valve body with spool, be provided with high strength material valve seat at the spool conical surface and valve body contact place, the upper end of described push rod has cylindrical cavity, is provided with spring in described cavity, one end of described spring is fixed in cavity, and the other end stretches out the end contact of cavity and spool.The utility model, by arranging cavity on push rod, being provided with spring in cavity, when push rod resets, due to the effect of spring force, can realizing rapidly the reset of push rod, be active in one's movements, than not having spring, resetting more reliable.
Description
Technical field
The utility model relates to shower nozzle field, particularly relates to a kind of by regulating the shower nozzle cover of shower nozzle front end and the position of shower nozzle to realize shower nozzle that is closed, adjustable spraying effect.
Background technology
Closely, one is that to be commonly called as one be more professional saying to the meaning of shower nozzle and nozzle.Shower nozzle is a variety of sprays, spraying, oil spout, parts very crucial in abrasive blast equipment, or even critical piece.Be broadly divided into by the multifunctional spray head of shower nozzle, afforestation irrigation sprayer, the Rocker arm spray head of agriculture land for growing field crops pouring, agricultural greenhouse greenhouse mini sprinkler, industrial anti-dust shower nozzle and special nozzle.
In the use procedure of shower nozzle, shower nozzle adopts mode in parallel to be arranged on pipeline, by unified valve opening and closing.In order to meet the needs of actual conditions, especially the occasion needing to control separately some or several shower nozzle and open and close, valving separately again on the pipeline of each shower nozzle of being everlasting under prior art condition, thus, the demand of valve significantly rises, and adds cost to a great extent.
Utility model content
The utility model, in order to overcome deficiency of the prior art, provides a kind of by regulating the shower nozzle cover of shower nozzle front end and the position of shower nozzle to realize shower nozzle that is closed, adjustable spraying effect.
The utility model is achieved through the following technical solutions:
A kind of have the shower nozzle opening and closing function, comprise water pipe, shower nozzle cover, shower nozzle, by the external screw thread on water pipe and the internal thread rotation tight fit on shower nozzle between described water pipe and shower nozzle, by the internal thread rotation tight fit on the external screw thread on shower nozzle and shower nozzle cover between described shower nozzle cover and shower nozzle; Described shower nozzle is semicircle foremost, and be drilled with the oblique hole be arranged symmetrically with above, described shower nozzle cover front end is semi circular shells, and rear end is cylinder, semi circular shells has the shower nozzle lipostomous be sealed and matched with shower nozzle front end semicircle, shower nozzle cover is drilled with spray orifice in the axial direction.
Spray orifice on described shower nozzle cover, when shower nozzle and shower nozzle lipostomous close, is completely enclosed.
Described shower nozzle is provided with convex shoulder, facilitates the assembly and disassembly of shower nozzle and water pipe.
When spraying implemented by needs, rotation spray head-shield, regulate the distance between shower nozzle cover and shower nozzle, the liquid sprayed from the oblique hole shower nozzle sprays from spray orifice after assembling in shower nozzle cover, shower nozzle cover between shower nozzle when different positions, the spray effect of ejection is different.
When closing shower nozzle, before rotation spray head-shield to shower nozzle lipostomous and shower nozzle, end in contact closes, and spray orifice is closed in shower nozzle front end, stops liquid ejection.
As optimal technical scheme of the present utility model, the oblique number of perforations on described shower nozzle is four.
As optimal technical scheme of the present utility model, described shower nozzle semicircle foremost applies one deck abrasive rubber, strengthen sealing effectiveness.
Compared with prior art, the beneficial effects of the utility model are: the utility model by by shower nozzle cover be arranged between shower nozzle be threaded, thus the convenient distance regulated between shower nozzle cover and shower nozzle, reach the object of adjustable spraying effect and realize the closed function of shower nozzle, structure is simple, economical and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, shower nozzle cover; 1a, spray orifice; 1b, shower nozzle lipostomous; 2, shower nozzle; 2a, oblique hole; 2b, convex shoulder; 3, water pipe.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of shower nozzle with keying function, comprise water pipe 3, shower nozzle cover 1, shower nozzle 2, by the internal thread rotation tight fit on the external screw thread on water pipe 3 and shower nozzle 2 between described water pipe 3 and shower nozzle 2, by the internal thread rotation tight fit on the external screw thread on shower nozzle 2 and shower nozzle cover 1 between described shower nozzle cover 1 and shower nozzle 2; Described shower nozzle 2 is semicircle foremost, be drilled with the oblique hole 2a be arranged symmetrically with above, described shower nozzle cover 1 front end is semi circular shells, and rear end is cylinder, semi circular shells there is the shower nozzle lipostomous 1b be sealed and matched with shower nozzle 2 front end semicircle, shower nozzle cover 1 is drilled with spray orifice 1a in the axial direction.
Spray orifice 1a on described shower nozzle cover 1, when shower nozzle 2 closes with shower nozzle lipostomous 1b, is completely enclosed.
Described shower nozzle 2 is provided with convex shoulder 2b, facilitates the assembly and disassembly of shower nozzle 2 and water pipe 3.
When spraying implemented by needs, rotation spray head-shield 1, regulate the distance between shower nozzle cover 1 and shower nozzle 2, the liquid sprayed from the oblique hole 2a shower nozzle 2 sprays from spray orifice 1a after assembling in shower nozzle cover 1, between shower nozzle cover 1 from shower nozzle 2 when different positions, the spray effect of ejection is different.
When closing shower nozzle 2, before rotation spray head-shield 1 to shower nozzle lipostomous 1b and shower nozzle 2, end in contact closes, and spray orifice 1a is closed in shower nozzle 2 front end, stops liquid ejection.
As a preferred embodiment of the present utility model, the oblique hole 2a number on described shower nozzle 2 is four.
As a preferred embodiment of the present utility model, described shower nozzle 2 semicircle foremost applies one deck abrasive rubber, strengthen sealing effectiveness.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
