" particularly to valves. having a plurality of inlets and outlets whereby the delivery of various types of fluids to separate or the same point may be regulated and'controlled i the valve casing.
and one whereby a plurality of diflerent types of fluids may be controlled by the valve for passage from separate points into or to spaced individual delivery points with-v out liability of mixing or intermingling of any of the various types of fluids.
.More specifically, the valve comprises a Valve shell having a plurality of inlets arranged in pairs spaced vertically or longitudinally of the valve casing and other inlets spaced circumferentially from the first named inlets, the said casing being provided with a pair of outlets which are adapted to be brought into communication by rotation ofthe valve plug with two of the inlets at the same time. 4
Other objects of the invention will appear. in the following detailed description and in the accompanying drawings wherein:
Figure 1-is a longitudinal section through the valve showing the core or plug therein.
Figure 2 is a top plan of the valve. 7
Figure 3-is a vertical section through Figure 4-is a cross section on the line 44 of Figure 3; 7
Figure 5is a cross section through the valve plug taken on the line 55 of Figure 1. v
Referring more particularly to the drawings, the improved valve comprises a cylindrical casing 1 provided with a tapered plug receiving bore 2 in which the valve plug 3 is rotatably seated. The valve plug 3 issubstantially frusto-conical shape, and is held against longitudinal movement within the casing 1 by any suitable approved type of construction, such as shown in Figure 1 of the drawing. The valve casing is pro- Vided with a plurality 'ofinlet openings 4,"
5, 6, 7 8 and 9, which extend transversely through the shell, and are arranged in pairs in longitudinal alignment of the body shell,
inlet openings may be provided without departing from the spirit of the resent invenas clearly shown in the drawings. It is to be understood that any desired number of tion, depending upon the num er of liquids The body shell 1 is provided with a pair of outlet openings 10 and 11, which are ar-' ranged in parallelism and in alignment with :0 be distributed through the valve struc- I ure,
each other longitudinally of the body shell.
The shell 1 is further provided with grooves 12'and 13 extending circumferentially. about the inner'surface of the shell, and having communication with :the outlets-10 and 11.
The and epth to carry a quantity of fluid equal to the capacity of the outlet openings.
Communication is established between any longitudinal pair of the inlet openings and the outlet. openings by bringing the substantially semi-cylindrical cut-out portions 14 and 15 which are formed in the plu 3 1nto communication with the desired i ets and with the grooves 12 and 13, respectively.
,The substantlally semi-cylindrical cut-out portions 14 and 15 are arranged in parallelism and in alignment longitudinally of the plug 3 and they have their innermost portions. spaced so as to prevent communi cation between the two recesses or cut-out portions.
By rotatlng the plug or core 3, the recesses 14 and 15 may be brought into communicarooves 12 and 13 are of sulficient size tion respectively with any of the-upper said inlet openings, a rotary valve plug within said casing and provided with a pair of substantially semicylindrical cut-out portions to establlsh communication between the respective inlets and said outlets- 2. In a valve, a valve casing provided with a plurality of inlets disposed in predetermined numbers above and below the transverse center of the casing, apair of outlets disposed in close proximity to and one above and one below the transverse center of the casing, a rotary valve plug in said casing and provided with cut-out portions for permitting communication between any one of each of the upper and lower sets of inlets and the respective outlets.
3. In a valve, a valve casing provided with a plurality of inlet openings spaced upon opposite sides of the transverse center of the casing, and provided with a pair of outlet openings positioned in close proximlt to the transverse center of the casing, sai casing provided with annular grooves the inner surfaces of which communicate with said outlet openings, and a rotary valve plug within said casing having a pair of substantially semi-cylindrical cut-out portions adapted to establish communication between the inlets and said grooves.
t In testimony whereof I aifix my signaure.
