Description
Technical field
The present invention relates to compressed sprayer, particularly relate to a kind of compression type sprayer safety valve.
Background technology
It is different that sprayer commonly used press 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 atomizer and inflate compressed sprayer.the inflation compressed sprayer is when operation, all wanting the operator to hold inflating bat-handle inflates to the inflator in sprayer, inject air and build pressure in the liquid bucket, then the continuous injection that causes a period of time, and when not spraying after the operator repeatedly inflates, may surpass due to the air pressure inside value ability to bear of staving, the serious consequences such as explosion can occur in staving, and at AEI After End of Injection, if insufficient release, can not directly open bung, otherwise can cause agricultural chemicals excessive, affect personal safety, if want abundant release, prior art is mostly sprayed by continuation, just the air pressure in staving is unsnatched, very bother, and waste is serious, therefore there is the people to design safety valve, but mostly there is complicated structure in existing safety valve, the shortcoming such as during use security is relatively poor.
Summary of the invention
The objective of the invention is provides a kind of simple in structure in order to overcome the shortcoming of prior art existence, and release is convenient, a kind of compression type sprayer safety valve of handling safety.
the technical scheme of a kind of compression type sprayer safety valve of the present invention is: the staving and the bung that comprise sprayer, be shaped with installing ring under bung, installing ring connects inflator, inflating rod is installed in bung, connect inflating bat-handle on inflating rod, under inflating rod, piston is installed, piston matches with cylinder inner wall, it is characterized in that being shaped with on described bung the mount pad of safety valve, be shaped with slideway and groove on mount pad, described slideway comprises inclined ramp peace slideway, have valve opening in mount pad, valve gap is installed on mount pad, the valve gap lower surface is shaped with slide block, slide block matches with inclined ramp peace slideway, under valve gap, valve rod is arranged, sealing ring is installed on valve rod, valve rod passes valve opening, the sealing ring of valve rod contacts with the upper oral part of valve opening, mounting spring outside the valve rod of valve opening lower end, be shaped with draw-in groove under valve rod, snap ring is installed in draw-in groove, snap ring one side is shaped with opening, snap ring snaps in the draw-in groove of valve rod through opening, snap ring contacts with spring, be shaped with retaining ring in the snap ring upper end, the outer wall of retaining ring contacts with the inwall of spring lower end.
The invention discloses a kind of compression type sprayer safety valve, when wanting release, rotate counterclockwise valve gap, the slide block of valve gap is along the inclined ramp upward sliding, and valve gap band ovable valve stem upward axis is to movement, valve rod drives snap ring upwards, spring on snap ring is squeezed, and when slide block moved to level and smooth road, the sealing ring on 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 staving, release is very smooth; In the time will stopping release, as long as be rotated further valve gap, slide block is moved in groove on mount pad, spring is downward top snap ring under the effect of restoring force, snap ring band ovable valve stem and valve gap move down, sealing ring on valve rod is contacted with the upper oral part sealing of valve opening, guarantee that in staving, air pressure can not leak, good sealing effect, be shaped with retaining ring in the snap ring upper end, retaining ring is stuck in the spring inwall, avoids 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 compression type sprayer safety valve, simple in structure, as long as rotate a bottom flange, simple, convenient during operation, 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 compression type sprayer safety valve of the present invention is shaped with 3 inclined ramps and the level and smooth road that is connected on described erection column, be shaped with 3 slide blocks under corresponding valve gap.Article 3, inclined ramp, level and smooth road and 3 slide blocks coordinate, and coordinate reliable.Described sealing ring and valve opening upper oral part contact-making surface are inclined-plane sealing or end face seal or inner wall sealing.Described valve gap and valve rod are the split manufacturing, through the assembling moulding.Described valve gap and valve rod are made one.
