SNOWDEN B. REDFIELD AND JULIUS NAAB, OF EASTON, PENNSYLVANIA, ASSIGNORS TO INGERSOLL-RAND COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY ACCUIIULATOF. TIMING ELEMENT FOR PRESSURE-FLUID-SUPPLY VALVES Application filed December 18, 1927. Serial No. 240,489.
This invention relates to displacement pumps, but more particularly to an accumu lator timing element by means of which the time permitted for the refilling of the pump tank in the well is regulated by a pressure accumulator, controllin the supply of pressure fluid for the pump. his timing element may be a gas accumulator, incase natural gas is used as the main pressure fluid supply or an air accumulator in case compressed air is used. In those cases in this specification in which the term exhaust to atmosphere is used it is to be understood that this exhaust will be to some tank or region of lower pressure than the supply when natural gas is used. The objects of the invention are to produce a displacementpump system which will operate with certainty and economy in conjunction with an accumulator timing element 0 in the form of a low pressure tank adapted to alternately receive fluid at lower pressure than the main supply, and exhaust said pressure from the tank. Another object of the in- 1 t vention is to enable the accumulator timing .25 receiver to eificiently control the auxiliary mechanism which regulates the operation of the pump. I
The invention is shown in one of its referred forms in the accompanying drawing, which is a diagrammatc view partly in vertical section and partly broken away, showing a displacement pump for a deep well, as an illustrative example.
Referring to the drawing, the compressor A for gas or air as the case may be, is connected to the main high pressure receiver B, in which the pressure may be 800 pounds more or less as desired. The main supply pipe C from the receiver leads to a main con- 40 trol valve D or chokevalve in the casing E, and from thence the ipe F leads to a well exhaust valve G in t e casing H, which in turn .is connected by the well supply pipe J to the well tank K adapted to be located in -15 the well. The well tank has a check valve L and a discharge pipe 0, and the foot piece ofthe discharge pipe preferably has a small hole P for aerating the column of discharging liquid as well understood on the air lift -50. principle.
The valve casing H has a vent Q which leads to atmosphere, or in case natural gas is used as the motive agent, this vent may lead to a region of lower pressure than the supply. The valve casing H is also connected by pipe R to the low pressure receiver S forming an accumulator timing element, in which the pressure may rise to 125 pounds more or less as determined by the reducing valve T in the pipe U which'connectsthe main receiver pipe C with the valve casing H. A timing control valve V located in the ipe U, may be a suitable needle valve to regu ate the time required for building up pressure in the timing receiver S to its maximum determined upon for the regulation of the system. The valve W in the pipe R leading to the timing receiver S is an adjustable choke valve preferably so constructed in any suitable manner that pressure fluid may ow freely into the receiver S, but flows out more slowly, for the prevention of freezing at the out- The timing receiver S is connected by pi 'e 17, to an auxiliary valve X which may he of any suitable type wherein ata predetermined pressure in the timing receiver S, the valve operates to admit said pressure fluid to a mechanism to be actuated,as for instance the change valve mechanism Y until the pressure in the receiver S again falls a certain amount below that required to operate the valve X, when the: auxiliary. valve returns to its original position allowing the change valve mechanism Y to be actuated to exhaust to atmosphere. I
Theauxiliary valve X shown in the drawing is in this instance like that disclosed in United States Patent No. 1,138,278 granted May 4, 1915 to Castle and Rogers, for Pres sure controlled valve and the same reference characters used in saidpatent are ap-, plied to similar parts on the auxiliary valve X herein shown. The valve chest 10 of the auxiliary valve X has an adjustable plug 14: at one end to which is connected the receiver pipe 17 leading to the low pressure timing receiver S. An adjustable spring cup 28 at the other end of the valve chest 10 has a vent29 to atmosphere, and a pipe 8 leads from the valve chest 10 to the cylinder 4 containing the plunger 5 of the change valve mechanism Y, all as disclosed in said Castle and Rogers patent. I v i 5 The change valve mechanism Y has the vent a and the pipe Z leading to one end of the exhaust valve casing H. A pipe b controlled by valve 0' supplies pressure fluid under high pressure from themain receiver pipe C to the valve casing of the change valve Y, so that the ball valve d actuated by the spring e in one direction and by the pm f and plunger 5 in the other direction controls the supply and exhaust of pressure fluid to and from one end of the exhaust valve casing H, for actuating the exhaust valve, and this change valve mechanism Y isin turn'controlled by the auxiliary valve X which is actuated in accordance with the rise andfall of pressure in the timing receiver S.
Let it be assumedthat the parts are in the positions indicated in the drawing, in which the main control valve D is open, and the exhaust valve G is inblowing position. As
shown, the valve G is in its right hand posi- -tion so that pressure fluid may pass from the pipe F through the valve casing H and through pipe J to the well'tank to discharge the oil or other liquid. The exhaust valve comprisesthe valve body G in the form of a shoe carried on'the stem 9 between the shoulders It and j of the plunger-heads Z0 and 0 connected by said stem g. The head 0 has an aperture p to permit pressure to equalize on both faces of the head and a set screw g engaginga slot r in the valve G guides the valve, which moves with the plunger heads. The under side of valve G has two grooves in s and t for controlling the four pipes J, Q,
R and U. "In the position shown, thetiming receiver pipe R is connected to the vent pipe Q and the pressure in the timing receiver is slowly falling. The auxiliary valve X has vented the change valve plunger 5 to atmosphere, so that the ball valve (1 is in downward position, and pressure fluid under highpressure from the main receiver B passes around valve d and by pipe Z to the exhaust valve casing H. The exhaust valve G is maintained in the blowing position shown because the pressures on the opposing actuating areas of the plungers k and o are equalized.
As soon as the oil is out of the well tank K, there will be a drop of pressure in pipes F and J and in the main valve casing E, and the sudden rush of pressure fluid through valve casing E, and around the valve flange to M which forms a restriction will blow the main control valve D-shut, so thatthe valve head '22 seats on the seat 10.
Themain valve D as shown has a cup :1:
whichfitstightly but slidably over the plug y and a pipe z'connects the inside of the plug and cup with an auxiliary receiver 30 which in turn is connected by pipe 31 to the main well pipe J. A valve 32 of any siutable form in pipe 31 permits pressure to build up slowly in receiver 30, but exhaust quickly, so that upon reduction of pressure in the well after discharge, the pressure inside of the cup w is relieved, and the main valve D will reopen under influence of spring 33, and because leakage of pressure through port 34in the main valve casing E has equalized the pressures above and below valve D.
.The drop in pressure against the pressure surface of the exhaust valve plunger head 0 unbalances the exhaust valve, and it will be moved to the left under the influence ofv the main pressure acting on head is, to exhaust position, in which case the main well pipe J will be connected to the vent pipe Q, to permit the well tank K to refill, and the timing receiver pipes U and R will be connected, so that pressure builds up in the timing receiver. \Vhen this pressure reaches a maximum after a predetermined time, permitted for the refilling of the well tank K, the auxiliary valve X will act to admit pressure fluid to the change valve plunger 5 and .shift the ball valve d to upward position,
thus relieving the pressure on plunger'head la and the exhaust valve will be shifted back again to its right hand position or discharge position as shown in the drawing. As soon as the auxiliary valve X again acts on drop of pressure in the timing receiver E to cause actuation of the ball valve d in the change valve casing, pressure will be restored to the exhaust valve plunger head is, but the exhaust valve will not move as the pressures on the heads are then balanced. Reduction of pressure in the well on discharge will cause the cycle to be repeated.
We claim:
1. A control mechanism for a fluid supply line, comprising a main pressure fluid supply pipe, a main control valve for the pressure fluid supply pipe, an exhaust valve, a timing accumulator to which the supply of pressure fluid is controlled by said exhaust valve, and a change valve controlling the exhaust valve and regulated by the timing accumulator.
