Description
Technical field
The utility model relates to a kind of flow control valve, particularly relates to the special accurate flow control valve of sprayer.
Background technique
Sprayer is the abbreviation of spraying equipment.Sprayer utilizes suction effect that liquid medicine or other liquid are become vaporific, is ejected into the utensil on other objects equably, is made up of compressed-air actuated device and tubule, nozzle etc.In rural area, sprayer is the indispensable important farm implements of prevention and elimination of disease and pests.Along with the development in epoch, spray structure is constantly updated, and manufacturing efficiency is high, time saving and energy saving, and the role of sprayer is very important.
In prior art, if the patent No. is 201320311747.X, the applying date is 2013.05.31 " a kind of Portable spray device ", this model utility designs compact applicable structure, the design of each component integrationization, easy to use, atomizing effect good, liquid is not easily revealed, and easily carries, grips use.But owing to lacking flow control structure, cannot flow control spray effect be passed through; Just simply control flow even if having or need manually to control, the actual object not having precisely control, awaits making further improvements.
Model utility content
For the present situation of above-mentioned prior art, it is excellent that technical problem to be solved in the utility model is to provide a kind of spray effect, the special accurate flow control valve of sprayer that piston movement is controlled flexibly.
The utility model solves the problems of the technologies described above adopted technological scheme: the special accurate flow control valve of sprayer, comprises valve seat, the first rubber ring, the second rubber ring, the 3rd rubber ring, piston, valve gap, spring and nut; Described valve seat is rotary structure, containing hollow molded cavity; Described first rubber ring, the second rubber ring and the 3rd rubber ring are embedded in the first groove of piston, the second groove and the 3rd groove respectively; Described nut is fixed on the topmost part, matches with valve gap.
Further, the form structure of described valve seat is made up of three parts, and outer surface is provided with second step limit, and its outside dimension matches with the internal diameter size of valve gap.
Further, described piston is arranged to the pattern of multidiameter shaft, is disposed with the first groove, the second groove and the 3rd groove from top to bottom, and groover rot diameter matches with the outside dimension of the first rubber ring, the second rubber ring and the 3rd rubber ring respectively.
Further, described piston is inserted into valve seat inside, matches with the internal structure of valve seat, realizes the effect moved up and down.
Further, described valve gap is rotary structure, and outer installment becomes ladder shaft-like, is formed with first step limit.
Further, the diameter compatible of described first step limit and nut closes.
Further, described nut external cylindrical surface is provided with many slots, between every bar slot every angle equal, and to be evenly distributed on 360 degree of circumferential surfacies.
Further, bulb is provided with above described nut.
Further, the lower end of described spring is through valve gap, and prop up the upper surface of piston, upper end is inserted in nut, and props up plane on nut inside, thus utilizes spring force by piston reset.
Compared with prior art, the utility model has the advantage of: the utility model compact structure, by lifting surface area change in structure, and then make that piston is stressed to be doubled and redoubled or to reduce, reach the effect immediately opened or close, solve the situation that other Flow valves can not be opened rapidly or close, effectively control spray effect.Generic flow control also just unidirectional control in addition, this patent product is double-direction control piston, and just can open as long as reach certain pressure or close, real realization precisely controls flow, controls spray effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is section of structure of the present utility model.
Embodiment
As shown in Figure 1, the special accurate flow control valve of sprayer, comprise valve seat (1), the first rubber ring (6), the second rubber ring (7), the 3rd rubber ring (8), piston (2), valve gap (3), spring (4) and nut (5), valve seat (1) is rotary structure, containing hollow molded cavity, piston (2) is arranged to the pattern of multidiameter shaft, be disposed with the first groove (21) from top to bottom, second groove (22) and the 3rd groove (23), and the first rubber ring (6), the first groove (21) on the specification of the second rubber ring (7) and the 3rd rubber ring (8) and piston (2), second groove (22) and the 3rd groove (23) match respectively, and the first rubber ring, second rubber ring and the 3rd rubber ring can be embedded in the first groove of piston respectively, entirety is formed in second groove and the 3rd groove, it is inner that piston (2) entirety after assembling is positioned at valve seat (1), the lower end of spring (4) props up piston (2) upper-end surface, upper end props up nut (5) inside upper surface, nut (5) is fixed on the topmost part of total, match with valve gap and be assembled together, spring (4) is positioned at the inside of the rear assembly of both assemblings, the outer surface of valve seat (1) is provided with second step limit (11), concordant with the external cylindrical surface of valve gap (3) after assembling, valve gap (3) is provided with first step limit (31), concordant with the maximum external cylindrical surface of nut (5) after assembling, nut (5) external cylindrical surface is provided with many slots (51), between every bar slot (51) every angle equal, and be evenly distributed on 360 degree of circumferential surfacies, nut (5) top is provided with bulb (52).
As shown in Figure 2, when piston (2) is not opened, pressure fluid, due to outlet obstructions, cannot flow, and liquid level contacts with the lower surface of piston (2) through valve seat (1); When piston (2) meets or exceeds setting pressure due to pressure at leisure, liquid has entered in valve gap (3) from below, thereupon through the material feeding mouth on piston (2) and hollow cavity, then the hollow cavity in nut (5) is continued across, finally flow out this mechanism, when the pressure in sprayer bottle is less than setting pressure, spring can promote the position that piston (2) automatically reverts to compression.Working principle of the present utility model is by lifting surface area change in structural design, and then makes the stressed rear pressure of piston be doubled and redoubled or reduce, and then produces Driving force at double, reaches and immediately opens effect; Also by lifting surface area change at double time closed, reach the instant effect closed.Design in bi-directional configuration, makes this Flow valve really realize the two-way automatic control of piston; This patent product is double-direction control piston, and just can open as long as reach certain pressure or close, real realization precisely controls flow, controls spray effect.Existing controlling method can not accurate flow control, and then accurately can not control spray effect, causes the spray effect that can not reach expection, wastes a large amount of spray, do not reach expected results simultaneously.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technological scheme described in previous embodiment, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment's technological scheme of the utility model.
