' 4 Claims. (01. 621) This invention relates to the maintenance of an adequate gas supply in a storage tank from intermittently or The invention relates more particularl to storage tanks in which the gas is produced by evaporation of a very cold liquid,
such as liquid nitrogen.
It is the general object of the invention to provide automatic means for supplying such cold liquid to the tank on the lowering of the normal gas pressure therein, and for maintaining substantially normal gas pressure as. gas is withdrawn from said tank.
The invention further relates to arrangements and combinations of parts which will be hereinof mechanism embodying the invention;
Fig. 2 is an enlarged sectional elevation of certain parts shownin Fig. 1; and
Fig. 3 is a view similar to Fig. 2 but showing a modified construction.
Referring to Figs. 1 and 2, a gas tank T is mounted on. a support l and may be provided with heat-absorbing fins or discs l2. Gas is provided in the tank T by evaporation of a cold liquid, such as liquid nitrogen, which is supplied to the tank through a feed pipe l4. Such evaporation produces gas under pressure and is facilitated by heat absorbed from the support H1 or from the fins I2. The gas may be discharged from the tank T through a pipe l6 which is under the control of a valve H.
The upper end of the feed pipe l4 connects into a relatively small inner or feed tank 20, normally filled with a cold liquid such as liquid nitrogen. The inner tank is preferably lined with heatinsulating material 22 and has a thin inner metallic lining 23.
The tank 20 is enclosed in a somewhat larger storage tank 25; also adapted to contain liquid nitrogen. The storage tank 25 is enclosed in a still larger outer tank which is normally filled with liquid oxygen. This tank may be covered with a thick layer of insulation 3|.
The storage tank 25 may be filled with liquid nitrogen through a feed pipe 32 having a shutoff valve 33. The outer tank 30 may be similarly filled with liquid oxygen through a feed pipe 35 provided with a shut-off valve 36.
The storage tank 25 may be vented on occasion through a pipe 4|! having a shut-off valve 4|.
The. pipe 4|! may also be provided with a safety .valve 42 for a purpose to be described.
A pipe 45 extends upward from the inner or feed tank 20 through the upper ends of the tanks 25 and 30 and is closed at its upper end, as shown at 45a in Fig. 1. Valves 5|] and 5| (Fig. 2) are mounted in spaced relation on a valve rod 53 which extends upward inside of the pipe 45 and which has a cylindrical iron armature 54 mounted on its upper end and loosely slidable in the tube 45.
The upper end of the tube 45 extends into a solenoid coil 56 connected by wires 51 and 58 to a battery B and switch S. Wires 60 and 6| connect the batter B and switch S to terminals 62 which may be connected by a cross bar 53 on a plunger 61. The lower end of this plunger'is connected to a bellows operator mounted on and connected into the tank T.
When the tank T is under pressure, the bellows operator lifts the bar 63 against the pressure of a spring 64 and thus breaks the solenoid circuit. When the pressure in the tank T is lowered,the bar 63 drops to complete the solenoid circuit.
The Valve rod 53 is normally pressed downward by a spring 66 to seat the lower valve 5| and to thus close the upper end of the feed pipe I l. The tube 45 is provided with ports- 68- (Fig. 2) through which nitrogen may flow from the storage tank 25 to the inner or feed tank 2|] when the valve 5| is thus seated by the spring 66 and the valve 50 is open. The spring 65 (Fig.2) is strong enough to seat the valve 5| against the normal gas pressure in the tank T.
If any substantial amount of gas is drawn out from the tank T through the pipe l6 and valve H, the gas pressure in the tank T will drop, thus allowing the bar 63 to close the circuit through the solenoid 56. This will energize the solenoid to raise the rod 53, closing the upper valve 50 and opening the lower valve 5|.
The liquid nitrogen contained in the inner or feed tank 20 will then flow down through the pipe I4 into the gas tank T, where evaporation will promptly take place.
The gas pressure in the tank T will then rise until the bellows operator 65 breaks the solenoid circuit and allows the valve rod 53 to drop. This seats the lower valve 5| to stop the feed of liquid nitrogen to the gas tank l0, and opens the upper valve 50 to admit more liquid nitrogen to the feed tank 20 from the storage tank 25.
The entire operation is automatic and will be repeated as often as gas is withdrawn from the tank T in any substantial amount.
The discharge of the liquid from the inner or feed tank 20 to the gas tank I on substantial lowering of the gas pressure in the tank 'I will be accelerated if the valve construction shown in Fig. 3 is substituted for the valve construction shownin Fig. 2.
In Fig. 3, an inner or feed tank 18 is mounted at the upper end of the feed pipe Ma and is provided with heat-insulating material H and with an inner lining 12. A valve rod -14 extends up through a pipe 15 provided with ports 16, all as previously described. A cross bar I! is secured to the lower end of the rod 14 :and supports two plungers 88 and 8!. The plunger 80 has upper and lower valves 82 and 83 which function the same as the valves 50 and 51 in Fig. 2.
The plunger 8| also has upper and lower valves 85 and 86. The upper valve 85 closes a port 88 in the upper end of the tank when the valve 85 is raised, and the lower valve 86, when lowered, closes a port '88 at the upper end of a'pipe 91 which extends upward from the lower-end of the tank 10 and which is open at its lower end through a plate 92.
A coil spring 93-seats the valves 83 and'86 when there is normal pressure in the gas tank, 'as in the previous construction. The rod 14 .is solenoid-operated and pressure-controlled as :previously described. When the pressure in the gas tan'kdrops, thesolenoid circuit will be-closed, the rod '14 and associated valve parts will be raised,
andthe liquid in the tank 10 will flow downward through the pipe Ma. At the same time, air or gas may flow upward through the pipe 9| and through the port 80 to relieve any gas-bind in the tank 70 andto'thus facilitate discharge therefrom. 1
With both forms of the invention as herein shown, a gas storage tank will be automatically and promptly replenished with an evapcrative.
liquid-on any substantial drop inpressure in the gas storage tank.
Any momentary rise in pressure in'the storage tank 25, due to the opening ofthe upper valve '50 o'r-82, will'berelievedby the safety valve 42.
- Having thus described the invention and the advantages thereof, it will be understood "that the invention is not to be limited to the details herein disclosed; otherwise than as set forth in the claims, but what is claimed is:
1. In a gas storage apparatus, a gas storage tank, an inner liquid-supply tankconnected thereto, a liquid storage tank surrounding said inner liquid supply tank, means to fill said liquid storage tank, means to feed an evaporative liquid from said liquid storage tank to said inner liquid supply "tan-k, meansto feed liquid fromsaid inner liquid supply tank to said gas storage tank, said 4 first and second feeding means operating alternately, and control devices for said two feeding means which are responsive to pressure changes in said gas storage tank.
2. In a gas storage apparatus, a storage tank, a'liquid supply tank of relatively small capacity and which is connected to said storage tank and which is normally full, feed and discharge valves for said supply tank, an operating rod connected to both of said valves and elfective to open and close said valves simultaneously but alternately,
