SIIIIONS, 0F EASTON,-PENNSYLVANIA, ASSIGNOR T0 INGERSOLL-RAND COMPANY, OF JERSEY CITY, NEW JERSEY; A CORPORATION OF NEW JERSEY OONTBOL HECHANISM FOR PRESSUBE-FLUID-SUPPLY LINES i Application led November 12,1927. Serial No. 232,801.
This invention relates to displacement pumps, but more particularly to a system 1 n which the refilling period of the well tank 1s preferably regulated by a timing receiver 5 forming an accumulator.
The objects of the invention are to simplify and cheapen the manufacture of the pump, obtain certainty and precision in action, and economy in operation.
Other objects are to enable the main control valve to be controlled by a main change valve, and the timingv recelver to be controlled by an auxiliary change valve, both of which valves are simple in construction, cheap to manufacture, and do not readily get out of order.
The main change valve is preferably controlled by an auxiliary control valve of any suitable or standard construction and the other change valve may be controlled by the main line pressure for simplicity of operation. The auxiliary control valve is preferably responsive to the pressure in the timing receiver, which constitutes a simple and convenient mode of operation.
The entire controlling apparatus may be assembled in small space, so that it is compact, and there are no complicated parts requiring special attention.
I do not confine myself to the speclal number of elements enumerated as the functions of several elements may be combined in one element in a single valve casing, without dearting from the spirit of my invention.
The invention is shown in one of its preferred forms in the accompanying drawing which is a diagrammatic representation of a displacement pump, partly broken away and partly in vertical section.
Referring to the drawings, the well tank A is adapted to be located in the Well B which may be provided with the casing C. The tank has the usual hi h pressure fluid supply pipe D and the discarge pipe E leading to the gas trap F, in case natural gas is usedas the pressure motive fluid. The foot piece of the discharge pipe is preferably provided with the hole G for aeration urposes on the principle of the air lift. he gas trap F has a vent pipe H to which other vent pipes of the system may be connected. In case compressed air is used as the pressure iiuid medium, this vent will lead to atmosphere, but in the case of gas, .the Vent may lead to a region or tank of lower pressure than themain supply.
A receiver J forms a source `of high pressure fluid supply and another receiver K forms a low pressure timing accumulator, in which the gas or air is permitted to accumulate under low pressure and up to a predetermined maximum pressure for a time sufficient to allow the well tank A to be refilled With oilor liquid to be pumped.
An auxiliary control valve X preferably constructed like the pressure controlled valve shown in United States Patent No. 1,138,278 granted May4, 1915, to Castle and Rogers is connected to the timing receiver by the pipe 17 fitted into the adjustable plug 14 at one end of the auxiliary Valve chest 10. A spring cup 28 at the other end of the chest 10 is connected by pipe 30 to the pipe 31 which connects with the vent H. The reference characters above used for the valve X are the same as those used for slmilar parts in the said Castle and Rogers patent and the valve operates to admit maximum timing receiver pressure through pipe 8 to the plunger L of the main change valve O to actuate said plunger and cause the main control valve P to open.v When the timing receiver pressure again falls a certain amount below that reuired to operate the auxiliary control valve ,then the auxiliary valve returns to its original position, allowingthe cylinder Q, ofthe change valve plunger L to exhaust back through pipe 8 and pipe 30 to the vent pipe 31 and gas trap vent H.
The well tank A is provided with a well exhaust valve R in the casing S connected by pipe 32 to the vent pipe 31. The exhaust valve R is moved to closed position when the main pressure fluid is supplied to the well tank A from the main receiver J through pipe 33, main valve P and pipe 34 connected to the well pipe D. The holes 35 in the exhaust valve throttle the live pressure andy cause pressure to be built up to close the valve against the spring 36. Upon reduction of pressure in the well tank A after discharge, the exhaust valve is opened by the spring 36.
The main control valve P has a cup a tightly but slidably titting the hollow plug Y) which is connected by pipe c to the casing ot the main change valve O. A ball valve d controls the pipe c and vent pipe e, so that when the ball (Z is in the up position shown in the drawing, the back o the main control valve P is relieved of pressure and the main valve opens and remains open under the influence ot the spring f until the well tank is discharged. The 'drop in pressure in the well and in the valve casing T causes a rush oit' pressure fluid over the collar g ot the main valve P and through the restricted opening between said collar and the valve casing which blows the valve shut. The valve neck t is of slightly smaller diameter than the inside of the valve cup a forming opposed dillierential pressure areas with the larger area inside the cup and when pressure is restored inside the valve cup, the valve will close and remain closed until pressure is again relieved inside the cup.
The auxiliary change valve U is similar to the main change valve O, but controls the supply and exhaust of low pressure fluid to and from the timing` receiver K. The high pressure pipe t7' leads from the main receiver pipe 33 to the casing of the change valve O as shown, and a branch pipe 7c leads from pipe j to the casing of the auxiliary change valve U. A reducing valve V of any suitable type is located in the pipe 7c and also a needle valve 0 forming a timing receiver control valve to regulate the time required to bring the timing receiver or accumulator up to maximum pressure. A pipe p connects the change valve U with the timing receiver K and a ball valve g controls the low pressure pipes k and p and the vent pipe r. A high pressure pipe s connects the cylinder t of the auxiliary change valve plunger u with the main well pipe 34 so that during discharge of the Well tank A, high pressure fluid is supplied beneath the plunger u and the ball valve Q is raised from its seat, which vents the timing receiver' K through pipes y) and r to the vent pipe 3l.
Assuming that the parts are in the positions indicated in the drawing, in blowing position, thernain control valve P is open, and the exhaust valve R is closed. The ball valves al and g of the change valves O and U are in raised position, which indicates that the cup 0r back of the main valve P is vented and the timing receiver K is vented and losing its pressure.
lVhen the well tank A is discharged, the main control valve P automatically closes due to the sudden rush of pressure fluid around the collar or flange g and the drop in pressure in the timing receiver K has caused the auxiliary control valve X to return to its initial position which vents the pipe 8 leading from the plunger L of the main change valve O through pipe 30 to pipe 3l. The plunger L moves down and ball valve al changes position which restores pressure inside the cup a of main valve P and holds valve shut.
The drop in pressure in pipe s leading t the plunger u or auxiliary change valve f causes said plunger to move downward, and the consequent change of position orp ball valve g permits pressure to build up in the timing receiver K through pipes 7e and p. The time interval required lor the building up ot' pressure in the timing receiver is sulficient for the reiilling of the well tank A, and when maximum pressure is reached in the timing receiver K, the auxiliary control valve K again operates, pressure is restored underneath plunger lli of the main change valve O, which relieves the pressure inside the main valve cup a, and the main valve opens. rlhe restoration of pressure beneath plunger u of the auxiliary change valve U again vents the timing receiver, and the cycle is repeated as the tank A is discharged and refilled.
