35 Claims. 7 (01. 277-24) This invention relates to valves and more particularlya new and improved multi-port, rotary plate type valve so designed and constructed that it may be used interchangeably on water softeners and filters.

In another application, Serial No. 560,303, I have disclosed a rotary plate type valve in which the plate seats on a ported gasket and has means for raising the plate oil the gasket when it is desired to shift the valve to another position. It is the principal object of my present invention to provide a valve of a similar type but constructed to provide separate, small gaskets on the plate for engagement with seat rings on the body, thus making it more practical to provide larger'sizes of valves of this type and enabling replacement of gaskets at comparatively low cost. I ther object of this invention to provide novel means for raising, turning and seating the plate under spring pressure, the said means being so constructed that the spring pressure does not function as a drag upon the turning of the plate,

, whereby to facilitate manual operation of the valve, especially in the larger sizes.

Another important object consists in the provision in a valve of the kind mentioned of a plunger arranged to be raised andlowered with the rotary plate to close and open inlet ports through which the water or other fluid is delivered to the valve, whereby to prevent any flow during the shifting of the rotary plate.

Still another object consists inthe provision of a poppet type valve spring pressed toward closed position over one of the ports in the rotary plate and arranged to be opened by engagement of rods mounted in the body in the seating of the plate in different positions, whereby to enable the automatic closing off or opening of the port in the rotary plate accordingly asthe rods for operating the valve are omitted or included in the body passages. The valve operating rods are preferably threaded in the valve body for adjustment toward or away from the poppet valve, whereby to vary the opening of said valve and accordingly regulate the flow through It is a furthe valve, and thus utilize the poppet valve both Figures 1 and 2 are longitudinal cross-sections in planes corresponding to the lines l--l and 2-2 of Fig. 4, the rotary plate being shown unseated in Fig. 2;

The same reference numerals are applied to corresponding parts throughout the views.

The valve of my invention, as stated above, has been especially designed for use interchangeably on water softeners and filters. However, it is adapted for a variety of purposes and any reference hereinafter to water softening or filtering should not be regarded in any sense as imposing a limitation on the application of this invention.

The valve is suitable for industrial purposes and wherever it is desired to control the flow of any fluid in a similar manner. In the present case, as will soon appear, the valve when used with a water softener controls the flow of water for softening-and back washing, and controls the flowof brine and water in salt washing and rinsing. In its application to a filter, the valve controls the flow of water in filtering and back washing and also permits. washing out of raw, water from the filter left under the filter bed as a result of the back washing, before the filter is connected with the service line.

Referring to the drawings, the cast body of the valve is indicated by the numeral 10 and has a plurality of ports andpassages therein for cooperation with ports and passages in a rotary stem plate ll, whereby to control a system of communication between pipes connected with. the body and communicating with the passages thereof. The body Ill, in other words, constitutes the stator and the stem plate II the rotor. The plate I I is enclosed by a cover l2 fastened suitably by bolts l3 onto the body l0, with a gasket l4 compressed between the parts to prevent leakage. A valve stem l5 projects forwardly from the center 'of theplate II through a suitable stufiing box It provided in the cover, whereby to' permit turning the plate by means of a hand lever H. The lever II, as will soon appear, is capable of operation in such a way as to unseat the plate II by means of the stem l5, and then turn the plate to a desired position, and reseat the same. An arm l8 extends radially from the stem l5 outside the cover l2 and has a tooth H on the outer end thereof adapted to be received in any one of a plurality of notches 20 formed in an annular flange 2| projecting from the cover, whereby to indicate the position of the plate and lock the plate in a selected position against turning before unseating. The cover is preferably provided with numbered tabs in radial alignment with the notches 20 so that the operator can readily tell in what position the valve is set. Valves of this general type, known as rotary plate type valves, have usually been constructed with the plate held down in direct metal-to-metal contact with the flat seat on the body, with the result that when the plate was turned the parts became scored and leakage resulted. It was then only a question of time when the leakage would become excessive and repair or replacement would be necessary, which meant not only considerable expense but the annoyance of interrupted service. By having the plate arranged to be unseated before it is turned, as herein disclosed, the objection as to scoring is avoided. Furthermore, I am thereby enabled to utilize gaskets 22 of rubber or other suitable material on the rotary plate around the ports thereof for engagement with metallic seat rings 23 suitably mounted in the ports inthe body I0. In that way, I secure a good leak-proof fit for the plate on the body without necessitating heavy pressure on the plate as was heretofore the case where a metal-to-I'netal contact was relied upon. The gaskets 22 are suitably held in place by rings 24 fastened by screws to the plate ll. Bushings 25 inserted in the ports in the plate project from the plate sufliciently to center the gaskets and keep the latter from spreading and getting out of shape as a result of the compression thereof onto the seats. It is, of course, a matter of no great expense to replace, these individual gaskets and this design is, therefore, ideal for the larger sized valves. The seatrings 23 can also be produced at comparatively low cost and are threaded or otherwise held in place for easy removal and replacement should that ever become necessary.

l2 and has a center bearing 21 through which the end of the stem l5 projects and in which the neck 28 of a rotary head 29 is swiveled (see Fig. 8). The hand lever I! has a clevis 30 provided on the end thereof in which the end of the stem I5 is pivoted by means of a cross-pin 3!. The sides of the clevis are of substantially .circular form, as shown, and trunnions 32 project from opposite sides at the center with the crosspin 3I-at a predetermined radius with respect thereto. These trunnions have plates 33 bearing thereon under pressure of coiled compression springs 34 carried on bolts 35 mounted on the head 29 and serving as guides for the plates 33. When the lever i1 is in the position shown in Figure 1, the pressure of the springs 34 1s transmitted through the stem 15 endwise to the plate II to seat the gaskets 22-under a certain pressure onto the seat rings 23. ,The clevis 30 has flats 30 provided on the periphery thereof at the proper point to insure ampleclearance between the clevis and rollers 36 mounted on the head 29, in this particular position of the lever,

whereby to insure proper seating of the plate ll 2, the clevis 30 rides on the rollers 36, so that the spring pressure is no longer active against the stem and plate but'is transmitted directly to the head 29. The movement .of the lever results in endwise movement of the stem [5 to unseat the plate H, as indicated in Fig. 2. When the lever I1 is in the position of Figure l, the trunnions 32 are substantially in dead center relationship with respect to the cross-pin 3| and rollers 36, the trunnions 32 being preferably a trifle past dead center so that the lever is urged against a stop 31 provided on the head, with the result that there is a definite end thrust on the stem ii at all times to keep the plate II seated. In the swinging of the lever I! from the position to Figure 1' to that of Fig. 2, it passes through the position illustrated in Fig; la, at which point the plate II is being unseated. Atv this point it will be observed that the pin 3| is on the center line a: and the trunnions 32 are on the center line e on opposite sides of the fulcrum line 1/ which passes" through the point of contact of the clevis 30 with the rollers 36. The springs 34, which hitherto acted to hold the plate ll seated under pressure, are now 'actuallyexerting a force in a direction to aid in the unseating. of the plate, so that the operator does not have to exert as much force on the lever H. as would otherwise be necessary. It is only through a; very small angle of movement of the lever ll that the operator has to work against the pressure of the springs 34, and that is in moving the lever from the position of Figure 1 toward that of Fig. 1a enough to bring the trunnions 32 past a dead center relative to the stem I5. As soon as the trunnions 32 pass the fulcrum line 1 the spring pressure becomes active in the opposite direction to assist in unseating The operator simply turns the stem I5 by means of the lever I'I, using the head 29 as a swivel support, and when the tooth I9 is directly over A yoke 26 is mounted on the end of the cover I the proper notch, the lever I1 is then swung back to its original position to seat the plate. There is no drag upon the operation inasmuch as the spring pressure is transferred from the plate tothe head when the lever is swung over to the position of Fig. 2, so that the manual operation of even the largest valve is' easily accomplished by hand.

In the description thus far, I have purposelyv softener or filter. Four ports, numbered 40-43 are provided in the body It in equally circumferentially spaced relation and at the same radius with respect to a central port 44. Pipes are suitably connected to the flanged portions of the body in communication with the ports 40-44. There are other smaller ports in the body l6, numbered 45, 46 and 46', disposed at the same radius with respect to the center port 44. The port 45 is midway between the ports 42 and 43 and communicates with the port 46 through 9. ports. The port 46 is midway between the ports 46 and 43 andis independent of these ports. The port 46' is midway between the ports 4| and 42 andis likewise independent thereof. As an aid to understanding the operation of the valve in the case of its application to a water softener, I have diagrammatically indicated in Fig. 3 by single lines a supply pipe 41 1 for conducting raw water to the valve as having communication with port 44; another pipe 46 leading to a service system, having communication with port 43; pipe 49 communicating with port 46 and extending to the top of a softener tank 50; pipe 5| communicating with port 42 and connected with the bottom of the softener 50; pipe marked Drain" communicating with port 4| and extending to the sewer or any other suitable drain receptacle, and another pipe communicating with port 46 and discharging into an injector 54 whose outlet is in communication with the aforesaid pipe 49 and which is arranged to draw brine from the brine tank 55 through a pipe 56 when a hand valve is opened. Another pipe 53' is shown extended from the port 46' to the brine tank 55.

The rotary plate II has four ports, numbered 66-63, correspondingly arranged to the ports 4|l43 in the body, and a plurality of small ports 64 clustered around the stem |5 corresponding in location to the port. 44 in the body. That is to say, the ports 66-63 are all disposed at the same radiusgyiith respect to the -steml5 and register with the ports 4643 in the different positions assumed by the plate, its positions being a quarter turn or half turn apart, as appears from the fact that there are three notches 20 disclosed-in Fig. 7 in the indexing-flange 2| to receive the tooth IS. The port 6| is a blind port, as clearly appears in Figure 1, and also from the fact thatit does not showin the plan view of the plate in Fig. 4. The ports 62 and 63 are interconnected by a hollow boss 65, as shown in Figs. 2 and 4, Four other ports half way between the ports 60-63, numbered 66-69, are provided on another radius with respect to the stem IS, the radius being the same as that for the ports 45, 46 and 46 in the body, whereby to provide for registration of these ports in the plate withthose in the body in different positions of the plate. The ports 66 and 69 go through the plate, as appears in Fig. 4, but ports 61 and 6B are blind. Ported gaskets 22' are provided for the ports 66 and 69 fastened in place by rings 24', similarly as the 23, and four small gaskets 22' to engage the seats 23' insures seating of the plate II in exactly the same way in every position and-each seat ringv will find a mating, ring-shapeddepression in a.

gasket when the plate is seated. There can be no question, therefore, as to the plate seating with a water tight fltin each and every position.

In operation, assuming that the valve is being used in connection with a softener 56 and brine tank 55, and that thoplate is in softening position, as indicated in Figure 1, hard or raw water is delivered through the pipe 41 and flows through ports 44, 64, 66 and 40 into the pipe 49 for passage downwardly through the bed of water softening material in the softener 50. The softened water discharged from the bottom of the softener through'pipe 5| is conducted through ports 42 and 62, and through passage through ports 63 and 43 to the pipe 46 leading to the service system. The softening operation is continued until the bed of water softening material reered throughthe pipe 41 and conducted through ports 44 and 64 and ports 66 and 42 to the pipe 5| leading to the bottom of the softener tank 50, so as to flow upwardly through the softener. The water discharged from the top of the softener through pipe 49, carrying with it the foreign matter, is discharged through ports 40 and 62, passage 65, and ports 63 and 4|, to the drain pipe, During this operation, the port 69 is in communication with the port 45 so that raw water may be delivered to the service system. However, the seat ring 23' for this port is internally threaded to receive a plug 10 to prevent raw water from getting into the service system. In other words, it is-simply a matter of including the plug 10 where the customer prefers not to have raw water get into the service system;

to allow any raw water to get into the service system, but in the average household, that is not considered objectionable. The seat ring 23' for the port 46' is similarly internally threaded to receive a plug 10a which has a small hole 16 therein so as to allow water to flow under pressure from under the cover I! through port 66 and port 46' at a predetermined rate into the pipe 53 to bring the level in the brine tank 55 up to a predetermined point. As a matter of fact, the operator will be instructed to allow the back wash to continue until enough water has been delivered to the brine tank to bring the level up to where it belongs, and in that way, the manufacturer of the water softener will be assured that the user will not cut short the back wash to an regenerated by reason of the bed not being cleaned and properly broken up prior to the salt wash. Another advantage in this procedure is that it gets away from the objection of salt crystallizing on the side walls of the brine tank all the way to the top and over the outside, with a resultant waste in salt; in accordance withthe present invention, the level in the brine tank is left so low throughout softening that whatever crystallization occurs on the side walls does not extend as high as the level to which water will be added during the back wash and in that way, all of the crystallized salt will be dissolved and used in the salt wash. The back wash is carried on for the proper time and then the lever I1 is operated to shift the valve a quarter turn in a clockwise direction to the No. 2 position (see Fig. '7) for what is known as the salt wash, or salting and rinsing. In this position, water is delivered under pressure from inside the cover i2 through the port 59 and port 46, thence through the injector 54 and pipe 49 to the top of the softener tank50. Under these conditions, the port 63 being in communication with the port 42 and port 52 in communication with port 4|, the bottom of the softener tank 50 is in direct communication with the drain 52, so that brine can be drawn from the tank 55 upon opening of the valve 51 and carried with the raw water for passage downwardly through the bed of water softening material to regenerate the same. Here again, raw

water may bedelivered to the service'system by.

' virtue of the fact that the port 60 is in communication with the port 43. However, I have provided a spring closed valve H on the plate Ii which will be opened each time the plate is seated provided there is a rod 12 in the port in 'the body II) for unseating the valve. As disclosed in Fig. 3, such rods are provided only in the ports 40 and 42. In the port 43, a plug 13 is inserted in lieu of a. rod 12 so as to allow the valve 'II to close the port 43 to shut off the flow of raw water to the service system du'ring'regeneration. Naturally, when a plug 10 is inserted in the port 45, a plug 13 will be inserted in the port 43 but if the port 45 is left open, it follows that a rod vI2 will be provided in the port 43, or the valve 1| omitted, so as to leave port 43 uncovered during regeneration and allow raw water to flow into the service system. The salt wash is continued for.

a'stated time or until a certain drop in level is noted in the brine tank, indicating that a certain amount of brine has been used suflicient for complete regeneration of the softener, whereupon the valve 51 is closed to shut off any further flow of brine. When there is no further flow of brine, it follows that the hard water can still flow through the injector 54 and pipe 49 into the top of the softener tank 50 so as to rinse the bed of water softening material and flush out any remaining brine and liberated calcium and magnesium. The rinse water leaving the bottom of the softener through the pipe 5| is, of

course, conducted to the drain pipe. The valve is leftin the No. 2 position long enough to complete the rinsing, after which the lever i1. is

valve 1i is arrangedto engage.

operated to shift the valve a quarter turn in a clockwise direction back to the original position which is' No. 3, to resumesoftening operation.

The valve I l, mentioned above, has a stem 14 working in aguide 15 provided on the plate II at the center of a valve seat 16 which the A yoke 11- is carried on the plate II to provide a guide for the other end of the valve stem, as indicated, and also provide an abutment for a coiled compression spring I8 bearing against the valve II and tending normally to seat the same. The rod 12, for unseating the valve ll in the seating of the plate TI is threaded in bosses 19 provided in the body. The threading of these rodsin the body permitsadjustment thereof to accordingly make the valve II open to a smaller or larger degree and thus regulate the flow through the valve. In that way, the valve II serves either as a shut-off valve or restriction valve. It is a simple matter to remove a rod 12 and substitute a plug 13, as inthe case of the port 43, where the valve is too close. Then,

too, where no shutting off or regulating of flow I moved outwardly in a sleeve 8| having apress fit in the central port 44 in the body Ill, whereby to close ports .82 and cut off the flow of water from the supply pipe 41 into the cover l2. In that way, there will not be any discharge of raw water through the drains 52 such as would otherwise occur. The saving in water is particularly worth while in large valve installations where the flow is proportionately greater. It is manifest that since the valve 80 is closed when the plate II is unseated and the drain pipe is at the same time placed in open communication with the inlside 'of the cover l2, there is no pressure existing in the cover. However, at the commencement of the unseating operation, the full pressure of the line 41 is acting against the plate II and if its full area were seated on the body l0, it follows that it would take considerable force to unseat the same, but this difficulty is avoided in accordance with my invention by having the seat rings 23 and 23' project from the body for engagement with the gaskets on the plate, whereby to leave the plate in spaced relation to the body when seated. It, therefore, takes a small fraction of the force that would otherwise be required to unseat the plate by means of the lever II.

It will be seen from Fig; 3 that the projecting seats'are spaced from each other a substantial distance so that in the seated position of the stem plate fluid may flow from the port 44 laterally outward between the stem plate and the face of the body member and upward into the space above the plate, the construction allowing free circulation of the fluid around the seats. This acts not only to equalize the pressure of the fluid on opposite sides of the plate I but increases the capacity of the valve. In other words, it enables me to keep the valve of small size and yet maintains full flow of fluid and avoids pressure loss in the valve.

Referring to Figure 1, it will be seen that I have provided an adjustable restriction valve -used instead of the valve II for regulating the ,flow in softening operation, that is, when the valve II is omitted and cannot be used for regulating the flow for softening, as previously described.

In the use of the present valve in connectionwith a filter, the port would be plugged inasmuch as there would be no brine tank 55.

The port 45 would be plugged only in the event the user preferred not to have raw water get into the service system, and in that event a plug 13 would also be used in the port 43 instead of a valve goperating roddl2. The port 46 would be connected directly with the line 49 without any injector 54, there being no brine tank. Assuming for the present purpose that tank 50 is a filter, during filtering the raw water delivered-through pipe 41 will be delivered through ports 60 and to the pipe 49 for entry into the top of the filter. leaving the bottom of the filter is delivered through pipe 5| and through ports 42 and B2, passages 65 and ports 63 and 43 to the service system through .pipe 48. In back washing, thejplate H is turned 180 so that the raw water is delivered to the bottom of the filter through pipe 5| and foreign matter is washed off the top of the bed in the filter through pipe 49 and conducted through ports 40 and 62, passage 65 and ports 63 and 4| to the drain pipe. During the back wash the port 69 will be in communication with the port 45 and if this port is not plugged it follows that raw water will be delivered to the service system. After the back Wash, assuming no raw water has been allowed to enter the service system, it is-desired to remove the raw water from under the filter bed, and for that reason the plate II is turned clockwise through 90 from the back wash position whereby to place the port 69 in communication with the port 46 so that raw water will be delivered to the top of the filter through pipe 49 for passage-downwardly through the bed. .The raw water is fiushed out from the bottom of the filter by filtered water and is conducted through pipe 5| and ports 42 and. 63, passage 65 and ports 62 and 4|, to the drain pipe. Following this operation, which may be termed ,a rinse, the plate II will be turned clockwise through another 90 back to the original position for filtering. It is apparent from this description how the present valve may be used interchangeably onwater softeners and filters by virtue of its novel design and construction.
