T.s. HARRIS AUTOMATIC VALVE Filed Nov. 20. 1922 Nov. 9 1926.
Patented Nov. 9, 1926.
unirse TES TI-IADDEUS S. HARRIS, OF WAVERLY, ILLTNOIS.
AUTOMATIC VALVE.
Application filed November 20, 1922. Serial No. 602,236.
This improvement relates to a modication of the construction previously shown and described in my Patent No. 1,433,007, oet. sa, 1922.
The object of this invention is to provide automatic means whereby one automatic electric pump may be used to supply two separate water systems from two correspending separate sources.
Some of the advantages of this construction over my former one are that it provides a more compact and simple construction, it combines the plunger and diaphragm of my former construction into one element which is connected into the discharge line from a pump in such a manner that the variations in the pressure in the different portions of the discharge line cause it to move to operate the valves, eliminating the necessity of a spring member to move the three-way intake valve in one direction. This construction also eliminates the necessity of check valves in the discharge lines and provides a built in automatic feed back check valve which compensates for any leakage back through the valves of the pump, thereby preventing the pump starting at frequent intervals, in case of such leakage.
The two water systems which are supplied by this valve may consist of two pipe lines with faucets, or, two storage tanks, or one storage tank for `soft water and a pipe line and faucet for obtaining hard water, or a tank for hard water and a pipe line and faucet for obtaining soft water, or, with the use of a check valve in the well water discharge line, two tanks and a fresh well water service line.
As illustrated in the accompanying drawing which shows a horizontal section through the median line, this valve comprises a three-way intake valve A and a three-way discharge portion B. The tubular casing of the intake end has port E. which is to be connected to the intake to the pump, port C which is to beconnected to the Well, and port D, which is to be connected to the cistern, said pump, well, and cistern not being shown in the drawing'. Valve F is fixedly attached to rod G and opens the passage from cistern to pump when the rod G moves to the right. Valve H is preferably slidably mounted on rod G being normally held in close proximity to sleeve I by coil J. It at least approximately closes the passage from the well to the pump when rod Gr moves to the right, but should it seat before valve K is seated, it allows the rod G to continue to move to the right until discharge valve K closes without encountering any resistance from member J.
Rod G extends through packing gland M to diaphragm chamber L, being lixedly attached to diaphragm N. One side of diaphragm chamber has an intake port R, which is to be connected to the discharge line from the pump, a discharge port S, which is to be connected to the hard water tank or hard water service line, not shown` and a discharge passage T, that is to be connected to the soft water tank or a soft water service line, not shown. A valve U in this passage is normally held closed by a spring V. Tf this valve is to be used with a soft water service line connected to port T spring V is preferably adjusted so that there is little or no pressure on valve U when it is seated, but if the valve is to be used with a tank connected to port T, spring V is adjusted to put some pressure on valve U when it is seated. A' passage W connects the passage T to the opposite side lof the diaphragn chamber.
A valve K is iiXedly mounted on rod G so that when rod G moves to the right port S is closed, valve K seating under `more or less pressure, which is communicated to it by rod G from diaphragm N. If this valve is to be used with only a service line and faucet connected to port T valve K is preferably made of somewhat greater diameter than when they valve is to be used with a tank connected to this port.
Should it be desired to use a pipe line and faucet connected to port S, instead of a tank, this does not affect the working of this valve in any material way, except that the automatic feed back check is then inoperative.
Tn operation diaphragm N is the oper* ating element, being moved to theright or left as the pressures vary on its two sides. In so moving valves H and F and also valve K are operated. For instance, if, when using this valve with two service lines, the soft water faucet is opened, the pump -is caused to start, by the drop inl pressure, and discharge water through valve U and passage T. Since there is a dropin pressure at valve U there is an excess of pressure thrown against the left side ofl the diaphragm N which causes it to move to the right, closing valve H and opening valve F so that water is drawn from the cistern, and after passing through the pump, is discharged through port R and passage T, to the soft water service line.
It, when using` service pipe lines from ports S and T, the hard water faucet is opened, the pump starts and throws a pressureinto the diaphragm chamber L. Since passage 'll has no outlet and there is practically no resistance to a small tlow through valve V, the pressures on the two sides or diaphragm L remain the same, rl`here is however a drop in pressure at valve l which causes it to move to the lett, moving rod G and valves ll and F to put'the pump suction line into communication with the well.
lt, when using two tanks connected to ports S and T, the pump is put in operation with no pressure in either tank (not shown) and the parts in the position shown, a slight pressure is produced on the lett side of the diaphragm since port S is rather limited in capacity Yand valve U is closed under a slight lressure ont spring V. This pressure immediately throws Vthe diaphragm to the right closing valves K and H and opening 'valve F. Cistern water is then drawn and discharged through valve U to the soft water tank. Since the pressure on the right side of diaphragm N is always the same as that above valve U, being in communication through passage W, there is an excess of pressure on its lett side so long as the pump is in operation lsince there is a drop in pressure of about tive pounds per square inch at valve U. Since the diameter of the effective portion ot the diaphragm is very much greater than that of port S minus rod G, a comparatively slight drop in pressure at valve will hold valve K closed, even though there is no pressure in the hard water tank and a high pressure in the diaphragm chamber, although it this difference becomes too great and valve K opens a little, the pressure on the left side of the diaphragm drops instantly and the pressure in the sott water tank, exerting its influence through passage lfi, throws diaphragm N to the lett, opening valves K and H and closing valve F. `When the pressure in the hard water tank becomes somewhat greater than that in the sott water tank the diaphragm N again moves to the right, practically instantly, since when valve l commences to close the pressure on the lett side of the diaphragm cham ber increases rapidly, until valve K is entirely closed and valve l is thrown open by the rise in pressure under it. llilhen the soft water tank is filled to the cutting out point of the switch the pump stops and the valve U closes, preventing any return ot the water lroni the. sott water tank to the hard water tank while the pump is idle.
In case the pressure in the hard water tank should exceed that in the soft water tank the diaphragm N moves to the right closing valve K and preventing any ilow from the hard water tank to the sott water tank when the pump is idle.
A special advantage or" this construction is that should there be a leakage past the pump valves the pump is not caused to start at Jfrequent intervals as it would be it ordinary check valves were used in the discharge lines, between the valve and the tanks, for valve l operates as an automatic feed back check which, while preventing a ilow from the hard water tank to the sott water tank while the pump is idle, yet opens to allow a flow from the hard water tank to the main discharge line to compensate for leakage past the pump valves. rlhis automatic movement oi valve l is caused by the pressure on the lett side ot the diaphragm falling below that on the right side, which latter, with the sott water tank well filled, is much greater than the pressure at which the automatic cut out-causes the pump to start.
