Description
Technical field
The present invention relates to compressed sprayer, particularly relate to a kind of compressed sprayer safety valve.
Background technology
It is different that sprayer commonly used is pressed the power source, can be divided into hand sprayer and power driven sprayer, and hand sprayer can be divided into on-inflatable formula liquid pump sprayer and inflation compressed sprayer.The inflation compressed sprayer is all wanted the operator to hold inflating bat-handle the inflator in the sprayer is inflated when operation, in the liquid bucket, injects air and build pressure, causes the continuous injection of a period of time then; And when after the operator repeatedly inflates, not spraying, may surpass the ability to bear of staving owing to the air pressure inside value, serious consequences such as explosion can take place in staving, and at AEI After End of Injection; If insufficient release can not directly be opened bung, otherwise can be caused agricultural chemicals excessive; Influence personal safety, if want abundant release, prior art is mostly through continuing injection; Just the air pressure in the staving is unsnatched, very trouble, and waste seriously; Therefore have the people to design safety valve, but mostly there is the structure more complicated in existing safety valve, shortcoming such as security is relatively poor during use.
Summary of the invention
The objective of the invention is provides a kind of simple in structure in order to overcome the shortcoming that prior art exists, and release is convenient, a kind of compressed sprayer safety valve of handling safety.
The technical scheme of a kind of compressed sprayer safety valve of the present invention is: comprise the staving and the bung of sprayer, under bung, be shaped on installing ring, installing ring connects inflator, and inflating rod is installed in bung; Connect inflating bat-handle on the inflating rod, inflating rod is installed piston down, and piston matches with cylinder inner wall, it is characterized in that being shaped on the said bung mount pad of safety valve; On mount pad, be shaped on slideway and groove, described slideway comprises inclined ramp peace slideway, has valve opening in the mount pad; Valve gap is installed on mount pad, and the valve gap lower surface is shaped on slide block, and slide block matches with inclined ramp peace slideway; Under valve gap, valve rod is arranged, sealing ring is installed on the valve rod, valve rod passes valve opening; The sealing ring of valve rod contacts with the upper oral part of valve opening, and mounting spring outside the valve rod of valve opening lower end is shaped on draw-in groove under valve rod; Snap ring is installed in the draw-in groove, and snap ring one side is shaped on opening, and snap ring snaps in the draw-in groove of valve rod through opening; Snap ring contacts with spring, is shaped on binding ring in the snap ring upper end, and the outer wall of binding ring contacts with the inwall of spring lower end.
The invention discloses a kind of compressed sprayer safety valve, when wanting release, rotate counterclockwise valve gap; The slide block of valve gap upwards slides along inclined ramp, and valve gap drives valve rod and upwards moves axially, and valve rod drives snap ring upwards; Spring on the snap ring is squeezed, and when slide block moved to level and smooth road, the sealing ring on the valve rod broke away from the upper oral part of valve opening; Draw off thereby make the space of air pressure between valve rod and valve opening in the staving, release very smoothly; In the time will stopping release,, slide block is moved in the groove on the mount pad as long as be rotated further valve gap; Spring is downward top snap ring under the effect of restoring force, and snap ring drives valve rod and valve gap moves down, and the sealing ring on the valve rod is contacted with the upper oral part sealing of valve opening; Guarantee that air pressure can not leak in the staving, good sealing effect is shaped on binding ring in the snap ring upper end; Binding ring is stuck in the spring inwall; Avoid spring when pressurized, power is excessive and flick snap ring, guarantees that snap ring can effectively be stuck in the draw-in groove of valve rod.This programme compressed sprayer safety valve, simple in structure,, simple, convenient during operation as long as rotate a bottom flange; During release, rotate valve gap with hand, the defensive position that rotate in place can be removed; Air pressure releases under valve gap, avoids air pressure and excessive agricultural chemicals to hurt human body, operates fool proof.
A kind of compressed sprayer safety valve of the present invention is shaped on 3 inclined ramps and the level and smooth road that links to each other on the said erection column, be shaped on 3 slide blocks under the corresponding valve gap.Article 3, inclined ramp, level and smooth road and 3 slide blocks cooperate, and cooperate reliable.Said sealing ring and valve opening upper oral part contact-making surface are inclined-plane sealing or end face seal or inner wall sealing.Said valve gap and valve rod are the split manufacturing, through the assembling moulding.Said valve gap and valve rod are processed one.
