Definitions
- Conventional water softeners are generally programmed to operate automatically through the well known cycles of service, backwash, brine slow rinse, fast rinse, and brine tank water refill. This programmed operation is achieved by means of acontrol valve which directs the flow of source water to the mineral tank and brine tank, soft or hard water to the service outlet, and unwanted water (during backwash and rinses) to drain.
- acontrol valve which directs the flow of source water to the mineral tank and brine tank, soft or hard water to the service outlet, and unwanted water (during backwash and rinses) to drain.
- Numerous control valves have been proposed in the past, the construction of such valves have varied but the function has remained generally the same, namely to achieve the above mentioned cycles.
- This invention is directed to the problem of providing the water softener cycles and, among its general objects, is to provide a simplified and effective control valve by means of which such cycles. can be achieved.
- FIG. 1 is a perspective of a control valve embodying this invention with parts broken away to illustrate the interior of the valve and being somewhat in schematic form so as to better illustrate the operation of the overall valve;
- FIG. 4 is a bottom plan view of the structure shown in FIG. 2;
- FIG. 5 is a section 'view taken generally along line 5-5 in FIG. 3;
- FIG. 7 is a section view taken 7-7 in FIG. 3;
- FIG. 9 is a section view taken generally along line 99 of FIG. 3;
- FIG. 10 is a section view taken generally along line 1010 of FIG. 6 and with operational parts removed;
- Valve body 12 is basically a three piece member including a main section 18, a top wall 20, and a bottom wall 22.
- the body pieces are made of a suitable plastic material, for example a plastic presently available commerically as Arcylafil 640-35 provides satisfactory regenerally along line sults.
- the pieces 18, 20, and 22 are connected by a suitable bonding adhesive and a tongue-in-groove type connection to provide'a leak proof seal for the interior of the valve body.
- FIG. 1 is somewhat of a general showing of the valve eliminating some details of constructions which have, however, been illustrated in other Figs.
- main section 18 includes an inlet port 24 in sidewall 64 for entry of hard water; an outlet port 26 also in sidewall 64 for exit of soft water for system usage; an opening 28 opening in bottom wall 22 (shown in dotted lines in FIG. 4 and in section in FIG. 11) through which hard water is directed to the mineral tank for treatment; an opening 30 in central wall 58 and generally aligned with an opening 31 through bottom wall 22 through which soft water returns to the valve; port 32 in sidewall 66 through which brine is drawn from the brine tank to be channeled through the valve to the mineral tank and through which replacement water is directed to the brine tank; and an outlet 34 in sidewall 64 connected to drain for discharge of water during, for example, the fast and slow rinse cycles for the mineral bed.
- Hub 36 extending laterally from sidewall 66, is adapted to receive a flow regulator valve 38, commonly referred to as a dole valve and which maintains a constant volume flow rate to drain outlet 34.
- Hub 40 in which port 32 is formed, includes a check valve assembly 42 positioned in bore 44. Port 32 communicates through the check valve and opening 46 in wall 58 with passage P and this channeling is used in directing brine from the brine tank to the mineral bed for regeneration as will be described hereinafter.
- Hub 40 includes a second bore 48 which carries a valve 50 (in FIG. the assemblies in the bores have been removed for purposes of illustration). Bore 48 communicates with bore 44 through a cross passage 52 which enters the bore 44 behind ball 54 of the check valve assembly 42. This channeling is utilized to direct water to the brine tank for refilling the brine tank after the mineral bed regeneration cycle. There is sufficient clearance between the valve member 50 and the inner walls of bore 48 to permit flow to passage 52.
- Wall 58 of main valve section 18 is disposed in a generally central location in the valve and extends between end walls 60, 62, and side walls 64, 66, the central, end and side walls being molded in one piece.
- the central wall carries the control valve ports, numbered 1 through 8 in the drawings, through which flow is directed as a result of selective opening of the ports by operation of the cam tank.
- Vertical walls are also provided and project on both sides of wall 58 and function to define flow channels associated with the ports for directing water in a manner which will become evident as this description proceeds, the walls will be numbered as required in the description.
- Wall 58 also includes holes 68 and 70 which communicate with each other via channeling and port 1 and hole 72 which is operationally between ports 6 and 8 and in the flow channeling to the brine tank.
- Ejector assembly 74 (FIGS. 7 and 8) is mounted in bore 76 and communicates with passage 78. Passage 78 has open communication with passage P, which communicates through opening 46, check valve assembly 42 and brine check valve 16 with the brine tank. Ejector 64 is operative to create a vacuum through the passages just described, i.e., P, and 46, causing ball 54 to be removed from its seat and brine to be drawn from the brine tank.
- Ports 1-8 are normally closed and are selectively opened for flow to achieve the conventional cycles of service, backwash, brine slow rinse, and fast rinse during which the brine tank is also refilled.
- the closure of ports I7 is achieved by balls A-G one of which is associated with each of the ports as illustrated in FIG. 1.
- Each of the balls AG is made of a material heavier than water so that they do not float, for example glass.
- Port 8 is closed by the combination of metal ball H, disc 144, and lever 134, a positive seal off is achieved at this port where even a small amount of leakage cannot be tolerated.
- Each of the ports l-7 which cooperate with a glass ball, is provided with a removable seat member 92 of suitable material which is positioned in a respective port and provides a seat for receiving a respective ball A-G.
- the seats 92 fit into each port and have an O-ring 93 associated therewith to insure a sea]. It will be noted that seat 92a at port 3 is a double seat to cooperate with both balls C and I. Being removable the seats can be removed and replaced during service as desired.
- Disc 144 is made of rubber, or the like, and seats directly on the end of extension 95 which forms port 8 and is held in place by ball H and lever 134.
- Balls A-G are all located above wall 58 as viewed in FIGS. 1 and 2 and, as will appear when the operational cycles are explained, the passages and channeling influencing flow direct all flow such that flow to a port when it is to be open and pass flow is from above wall 58. This produces flow over the balls tending to seat the balls in their respective ports. Thus water pressure urges the balls into the ports and they must be positively displaced to open the ports and when released are returned to engagement in their ports under the influence of the water.
- a second ball I is associated with port 3 and is located on the underside of wall 58.
- Ball I is generally made of a material which will float (e.g., polypropylene) so that it will normally try to assume a position seated in and closing port 3. However, when flow occurs down through port 3 it is readily displaced. Ball H holds disc 144 on port 8 and when the ball is released by lever 134 the inherent water pressure under the disc raises the disc to open the port.
- balls A-G normally tend to assume a position secured in their respective ports and a relatively simple arrangement is proposed for unseating the balls to open their respective ports. Being unable to float and disposed over the upperside of wall 58, which is normally horizontal, and with influenced flow being over the balls, the balls arebiased into engagement in their respective ports without the use of springs. Although springs can be used, the free movement of the balls when released from the ports is preferred.
- the arrangement for unseating the balls includes a number of levers 96 extending through top section for engagement with balls A-G.
- Levers 96 are rigid members of a suitable metal, such as brass, and are held captive in resilient discs 100 seated in a plate 102 overlying top section 20. Levers 96 are vulcanized to the discs providing a sealed connection, discs 100 are in turn seated in openings 106. The levers extend through clearance openings 110 in top section 20.
- Discs 100 are made of resilient material, e.g., rubber, and the inherent bias of these discs cause levers 96 to assume a generally upright position, spaced from, i.e., not in contact with, their respective balls A-G.
- the resilient discs oppose movement of the levers in a port opening direction and return the levers to the upright position after the opening force is removed.
- a notch and projection arrangement is provided between discs 100 and openings 106 locating the discs and thereby orienting the levers.
- cams 112, 114, 116, 118, 120, 122, 124, and 126 Movement of the levers to engage and unseat the balls is achieved by cams 112, 114, 116, 118, 120, 122, 124, and 126 as can be seen in FIG. 1.
- Cams 112-126 are provided withsuitable cam lobes to engage and move the levers and all are mounted on a shaft 128 which is driven by a timer (not shown) programmed to cycle the cams to achieve the necessary water softener cycles.
- cams 112-126 selectively operate their respective levers 96, and 134, to pivot the levers into engagement with and move the balls against water pressure to unseat the balls as required to achieve the various water softener operations.
- lever 134 ball H is moved to free disc 144.
- cams 112-124 carry lobes and the rise portion of the cams are used to operate their respective levers to displace balls A-G.
- cam 126 is adapted to operate its lever 134 on a fall portion of the cam and hence a lever arrangement has been provided to accommodate this reversal of this operation.
- cam 126 is intended to control the brine tank refill cycle and, therefore, is made adjustable to provide the prescribed amount of water to recharge the brine tank after the brine cycle. More specifically, cam 126 includes a first cam disc 126a and a second cam disc 126b.
- Cam disc 126a is fixed to shaft 128 whereas disc 126b can be rotated relative to the shaft whereby the cam fall opening can be set at a maximum where faces 130 and 132 of disc 126a are both exposed but can be reduced by exposing face 135 and moving that face toward face 132.
- Lever 134 is supported on a pin 136 for pivotal movement.
- Lever 134 includes a projection 142 which rides on the rise portion of cam 126 and holds lever 134 such that ball H urges disc 144 into engagement with port 8.
- projection 142 falls into the opening defined between surfaces 130 and 132 or 135 and 132, spring ball H is released and the water pressure under disc 144 lifts the disc to open port 8.
- cover plate 140 serves to hold resilient discs 100 and 104 in their respective openings, this cover plate and outer housing 146 were removed in FIG. 1.
- Cover plate 140 is attached to member 102 and member 102 to top section 20 by a suitable adhesive.
- Screw 137 is threaded into lever 134 and makes the actual engagement with ball H to thereby provide a measure of adjustment in the force with which the disc closes port 8.
- the service cycle will continue until the point is reached wherein the zeolite bed requires regeneration.
- the first step in regeneration is a backwash cycle which produces a reversed flow through the zeolite bed to loosen the bed.
- the levers associated with balls C and G are moved from engagement with those balls allowing the balls to seat in and close ports 3 and 7.
- Cams 112, 110, and 122 engage their operating levers to displace balls A, D, and F and open ports 1, 4, and 6, all other ports remain closed.
- Port 4 is also open during the backwash cycle and this port has direct communication with hard water entering inlet 24 through opening 80.
- the hard water passes from opening 80 through passage P and port 4 which has open communication with the underside of port 3 through channel 4a so that hard water can flow directly to and through service outlet 26 to meet water demands during the backwash cycle.
- port 4 remains open throughout the regeneration cycle to provide hard water service at this time. In accordance with conventional practice, the regeneration cycle takes place during the early morning hours so that the lack of soft water is not critical and hard water is sufficient to satisfy the demands at that time.
- ball I will be urged toward its seat in port 3 to insure closure of that port during the backwash cycle.
- a vacuum is created in area 78, creating a vacuum through passage P,, opening 46, and in the area of check valve 42.
- a pressure drop occurs across ball 54 of the check valve unseating the ball and causing brine to be drawn from the brine tank through the brine check valve and port 32.
- the brine is mixed with the water being discharged into the mineral tank and flows down through the zeolite bed. This will continue until the brine solution has been completely drawn from the brine tank at which time the conventional brine tank flow check valve will operate to interrupt communication between the valve, specifically port 32, and the interior of the brine tank.
- the brine circulates through the zeolite bed and returns to the valve through the opening 31. From passage P return flow proceeds through opening 30 to passage P down through port 2 to passage P (which is isolated from passage P, by wall 87 Port 2 communicates with opening 70 so that the brine solution flows up through opening 70 to and through drain outlet 34.
- a fast rinse cycle is provided.
- This fast rinse cycle is achieved by cam 114 remaining in engagement with its lever 96 to hold ball B away from port 2 and cam 124 engages its lever 96 to displace ball G from port 7 so that ports 2 and 7 are open, together with port 4 which maintains hard water service.
- hard water enters inlet 24, a portion thereof flowing to service through port 4 and another portion flowing through port 7 and from port 7 through passage P and opening 28 to and through the zeolite bed. It will be noted at this point that port 7 is larger than port 5 so that a greater quantity of water is being directed through the bed during fast .rinse as compared to slow rinse.
- Hard water passes down through the bed and returns as soft water through opening 31 to passage P and through opening and passage P to open port 2, which having open communication with hole 70, allows the rinse water to proceed directly through outlet 34 to drain.
- the valve Upon the completion of the fast rinse cycle, the valve operates to establish a service setting and service of soft water is resumed as described previously and until a subsequent regeneration cycle is called for.
