Description
Technical field
The utility model relates to sprayer, particularly relates to pressure regulation, the stable-pressure device of sprayer spray gun, belongs to the plant protection mechanism field, is mainly used in the hydraulic control of mister head soup and the open and close control of soup.
Background technology
In agricultural production,, need spray insecticide in order to prevent and treat the damage by disease and insect of crop.The most frequently used equipment for plant protection that is used to spray insecticide is exactly knapsack hand sprayer or power spraye, and the soup gauge tap of such sprayer adopts pressure-lift switch basically, and the part old product also has the rotary switch that adopts ball-valve type.These switches, simple in structure, easy to operate, can easily realize opening and closing function, particularly pressure-lift switch can also be realized a spray, or the function of spraying continuously, therefore is well received by consumers.Along with the continuous progress of modern agricultural technology, people not merely be satisfied with the sprayer droplet carefully, not simple requirement such as water clock, final purpose is to pay close attention to dispenser quality and last pesticide supplying effect; More and more pay close attention to the uniformity of droplet size in whole spray process; The uniformity that the continuity of spray, droplet distribute could prevent that like this leak-stopping sprays or resprays; Could guarantee that droplet can play best pesticide supplying effect uniformly attached to crop blade face or insect surface.And for knapsack hand sprayer or power spraye, the former adopts piston pump, though be provided with air chamber; But because manpower drives, frequency hand-manipulated is few, and piston stroke is long; So the soup pressure of the shower nozzle of flowing through height is inhomogeneous, and when causing pressure high, droplet is thin; Far firing range is prone to drift, and spray orifice is easy to wear; Defectives such as when pressure was weak, droplet was thick, and range is near, was prone to drippage, and environmental pollution is big, its result has influenced dispenser quality and effect.Equally also there is such problem in power spraye, and operating frequency is high, but does not have air chamber, so the spray pulse is obvious equally.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming that prior art exists, the droplet size that sprays when a kind of sprayer dispenser is provided evenly, spray is continuous, sprays pressure regulation, the stable-pressure device of the sprayer spray gun that is evenly distributed.
The pressure regulation of the utility model sprayer spray gun, the technical scheme of stable-pressure device are: comprise spraygun body, in main body, be shaped on the runner that communicates with the sprayer switch hole, it is characterized in that being shaped in the said main body pressure regulating valve hole that communicates with runner; Step is set in the pressure regulating valve hole, diaphragm is set on the step, valve is set in a side of diaphragm; Opposite side at diaphragm is provided with pressure regulating device, and described valve comprises diaphragm upper fixed seat, separating stand, ball sealer, last pressing spring and the spring dog screw that sets gradually, and the spring dog screw is installed in the main body; Described separating stand is shaped on the cylindrical shape valve chamber and the water outlet short tube of upper shed, is shaped on valve opening under the valve chamber, and ball sealer is arranged in the valve chamber and with valve opening and matches; The top of ball sealer contacts with last pressing spring; One of the water inlet of the upper shed passage flow duct of separating stand, the water outlet short tube end opening of separating stand contacts with diaphragm, one of the water outlet of the connection runner suitable for reading of water outlet short tube; Described pressure regulating device comprises diaphragm lower fixed seat, pressure spring, spring base and the pressure regulating seat that sets gradually; Pressure regulating seat is linked to each other with main body by screw thread, and pressure regulating seat is fixed on the edge of diaphragm on the step of main body, and pressure regulating seat is shaped on regulator hole; Screw press is installed in the regulator hole, and screw press links to each other with spring base.
The utility model discloses a kind of pressure regulation, stable-pressure device of sprayer spray gun, described spray gun also is sprayer switch, comprises parts such as switch main body, handle, button, valve.In use, soup feeds pressure regulating valve hole from runner, flows to the valve opening of separating stand again from pressure regulating valve hole; After soup flows through valve opening; Soup promotes diaphragm downwards, and diaphragm promotes the diaphragm lower fixed seat downwards, and the diaphragm lower fixed seat pushes pressure spring downwards; This moment, diaphragm disengaged the end opening of water outlet short tube, and soup flows into of runner water outlet from the water outlet short tube.And when hypertonia; Soup flows into pressure regulating valve hole, hypertonia make ball sealer move down with valve chamber in the valve opening sealing contact, soup can't pass through from valve opening at this moment; Thereby avoid hypertonia to cause the wearing and tearing of spray orifice, cause defectives such as thin, the easy drift of soup droplet; When pressure was too small, soup was through behind the valve opening of separating stand, owing to can't overcome the spring force of regulating spring; Thereby can't promote diaphragm downwards, the end opening of diaphragm and water outlet short tube keeps in touch always, and soup can not be ejected equally; Shortcomings such as the droplet of avoiding causing because of pressure is too small is thick, be prone to drippage, environmental pollution is big; Therefore only when the pressure size to fit, soup could spray from spray gun, and the spring dog screw is set in valve; Screw press is set in pressure regulating device; The thrust that can regulate pressing spring and pressure spring through rotation spring dog screw and screw press, thus the thickness that sprays droplet controlled, guaranteed to spray the quality and the effect of medicine.
Pressure regulation, the stable-pressure device of the utility model sprayer spray gun, described diaphragm upper fixed seat is shaped on push rod, and push rod contacts with ball sealer.Ball sealer can contact with valve opening downwards during hypertonia, when the pressure answer just often, push rod just under the effect of pressure spring with the ball sealer pushed home that makes progress.The pressure regulation pad is set between described pressure regulating seat and the diaphragm.The pressure regulation pad has been arranged, guaranteed the fitting tight property of pressure regulating seat and diaphragm.
