Application August 29, 1946, Serial No. 693,680
- 1 This invention relates to improvements in apparatus for mixing different liquids together in determined proportions, and the primary object of this invention is to provide a mixing valve, especially although not necessarily, for mixing together liquid insecticide, fertilizers and the like,
. with water in variable proportions and controlling the flow of the resultant mixture.
Another important object of this invention is to provide a readily portable mixing valve of the character indicated above which is designed to draw the liquid which is to be mixed with water or the like from the container in which the liquid is ordinarily sold or stored, the mixing valve having for this purpose means enabling directly connecting the neck or other outlet of the container to the valve.
Another important object of this invention is to provide a mixing valve of the character indicated above which is designed to be capable of being directly connected in a spraying hose between the hose and the spraying nozzle, and which is of such small size and compact and lightweight construction as to add little burden to the manipulation of the hose and spraying nozzle.
Other important objects and advantageous features of this invention will be apparent from the following detailed description and the drawings appended thereto, wherein merely for purposes of illustration, a presently preferred but non-limitative embodiment of this invention is set forth. It will be obvious to those skilled in the art that changes may be made in the construction and relative arrangement of the component parts of said embodiment without departure from the invention as hereinafter claimed.
In the drawings,
Figure 1 is a bottom plan view,
Figure 2 is a longitudinal section taken on the line 2-2 of Figure 1,
Figure 3 is a fragmentary top plan view of the rotary valve,
Figure 4 is a horizontal section taken on the line 4-4 of Figure 2,
Figure 5 is a top plan view of a nozzle, and
Figure 6 is a transverse section taken on the line 6-43 of Figure 5.
Referring to the drawings, in detail, the numeral 5 generally designates the body of the mixing valve, which may be a casting comprising a short cylindrical adapter 6 having internal screw threads I for reception and separable connection of the threaded neck or other outlet of a bottle or other container (not shown) of the liquids to be mixed with water. Said adapter 6 has a closed bottom or inner end 8 which is slightly conically depressed, as indicated in Figure 2, and formed with a concentric shallow cylindrical recess 9.
Formed on the said inner end or bottom of the part 6 is a diametrically extending elongated cylindrical part l6 having on one end an externally threaded :boss H for connection of a spray nozzle (not shown), and on the opposite end an internally threaded boss [2 for connection of a water hose (not shown).
A valve chamber formed in the part I!) coaxial with the cylindrical recess 9 comprises the reduced cylindrical portion l3 opening into said recess, and the further reduced bore I4 which opens into the cylindrical portion l3 and extends through the side of the valve body opposite the adapter 6.
On the elongated cylindrical part IE) on opposite sides of the portion l3 of the valve chamber are tapered discharge and intake passages l5 and I6 whose larger ends open through the bosse H and I2 respectively, and Whose smaller inner ends terminate in ports I1 and I8 respectively, opening through the side walls of the valve chamber portion l3.
By-passes l9 and 20 respectively, which are smaller in diameter than the ports [6 and ll, are formed through the bottom and inner wall 8 of the adapter part of the casting so as to open through diametrically opposite points of the bottom of the recess 9 at angles converging toward the axis of the adapter 6, the by-passes thereby opening into the adjacent walls of the .tapered passages l4 and 15 at points spaced outwardly from the corresponding ports I6 and I7. The by-pass !9, opening into the discharge chamber I5 is of a diameter greater than by-pass 28 which opens into the intake chamber [6;
The valve which fits rotatably in the valve chamber comprises a cylindrical part 2| conforming to the chamber portion [3, a disk part 22 con- '24 is fully registered therewith. The bore 25 is substantially smaller in diameter than the bore 3 24 to effect a substantially reduced fiow through the valve when the valve is positioned to register the bore 25 with the ports I? and I8.
The disk part 22 of the valve has diametrically aligned orifices 26, 26a, 21, and 21a, for registry with the by-passes l9 and 2B, the orifices 26 and 26a being of substantially the same diameter as the by-passes l9 and 2!) respectively, and the orifices 27 and 21;; being smaller in diameter than the orifices 2,6, and 25a respectively, the pairs of orifices being arranged so that the larger orifices 26 and 26a. will be registered with the by-passes, when the larger bore 24 of the valve is registered with the ports I1 and it, and the smaller orifices 21 and 21a will be registered with the by-passes when the smaller bore 25 of the valve is registered with the ports I7 and 48. In thiswaythe.
amount of liquid from the container connected to the adapter is fixedly proportioned for mixture to the amount of water through the valve, in accordance with the rotary position of the valve.
The outer exposed side of the disk part 22 of the valveis slightly conically depressed, in continuation oi'the surface of the adapter bottom 8, with a conical 'baflie 28 rising from its center.
In operationthe valve being turned to a positionin which one of the, bores 24, and a pair of the orifices 26 and 26a are registered with the ports Hand i8 and by-passes i9 and 20, a water hosebeing connected to the boss l2, and the boss 12 to a spray nozzle, and a liquid container being connected to the adapter 6, water will flow in the passage ii; under pressure toward the valve bore, which Yforrns a venturithroat, and pass at accelerated speed outwardly through the passage 15 toward the spray nozzle. In this transit, part of the water inthe passage 16' passes through the by-pass 20 into the liquid in the container and strikes against the bafile 28, thereby creating a turbulancewhich enhances the mixture of water and liquid inthe container. The contents of the container being then a mixture of liquid and water under pressure is forced out of-the by-pass tfl into the passage i5'where it rejoins the water moving at an accelerated speed through the valve and forms the focal mixture going to the spray 3W As indicated in Figure 4, the various valve bores and orifices are so positioned relative to the valve chamber ports and by-passes that the valve can be turned to positions in which these are either completely closed so that no flow through the valve takes place, or into partly open or closed position so that lesser fiow than provided by either of the two main open positions are made available. In all fully open or partly open positions of the valve, the relative proportions of water. and mixing liquid are maintained.
For convenience .in operating the valve to pro vide for predetermined mixtures, the valve stem or shank 23- is provided with an indicator disk 291 held in place by a nut ill-threaded thereon, and provided with position marks 3|, and a pointer 3-2,-0n the valve. body for cooperation therewith.
In, Figures 5 and 6 there is shown a nozzle 40 which is particularly adapted for use with the above described mixing valve 5. The. nozzle. 40 comprises a body 4| and a partially rotatable plate 42. The body 4! isannular having an internally threaded concentric bore 44 throughout its length and an annular recess 45 at the inner end of the bore 44 in which a seal, not shown, may be seated for sealing the nozzle 40- on the outlet end ll of the valve 5'. The body 4! is formed with an upwardly bowed or arched upper wall 46 having openings 41 formed therethrough.
An upwardly bowed baffle or valve 42 is rotatably mounted on the under side of the top wall 46 by a hollow rivet 48 through the apex of the wall 46 and valve 42. The plate 42 is provided with openings 49 which register with the openings 41 in the wall 46 to permit the passage of fluid from the bore 44 ther'ethrough in certain positions of the plate 42. For rotating the baffle 42 relative to the wall 46, there is provided a pin 50, fixed to the plate 42, which extends through an elongated arcuate slot 5| in the wall 46 in such a manner that movement of the pin 50 by an operator will rotate the plate 42 about the rivet 48 to a position where the holes 41 and 49 are aligned to permit a coarse spray, or to a position where the holes 47 are covered by the plate 42 to stop the fiow, or any intermediate position to provide an es d su at s rar- I o no mea o fine musin he xa t de a o s uct on eiadisclo dz bu aim all variations falling: withinthe purview Off the appended claims.
