- 1 Claim. (01. 23658) This invention relates to means for supplying fuel to burners and particularly burners used in conjunction with steam boilers.
An object of the invention is to provide means whereby either oil or gas may be supplied to the burner in a substantially automatic manner.
The invention further consists in the provision of an improved means for controlling the supply of fuel to the burner in such a manner to insure against over or under supply of fuel.
The invention, together with its objects and advantages, will be best understood from a study of the following description taken in connection with the accompanying drawings wherein:
Figure 1 is an elevational view of the invention.
Figure 2 is a top plan view thereof.
Figure 3 is an elevational view taken at right angles to Figure 1.
Figure 4 is an enlarged sectional view of a needle valve and pressure responsive means associated therewith for controlling the operation of the valve.
Figures 5 and 6 are detail sectional views taken substantially on the lines 5-5 and 6-6, respectively, of Figure 1.
Figure 7 is a detail view of the needle valve.
In accordance with the present invention and as illustrated in the drawings, there are provided two identical devices indicated by the reference numerals I0 and ma, respectively.
Each of the devices l0 and Illa comprises a vertical frame structure U at the upper end of which is a cylinder l2, and at the lower end of which is a cylinder |3. Operating in the cylinder I2 is a piston l4 that is provided with a stem l5 operating through a gland H5 in the bottom of the cylinder l2. Operating in the cylinder I3 is a piston I! having a stem l6 operating through a gland IS in the top of the cylinder l3. The ends of the stems l5 and H! are threaded and at said ends the stems are connected together through the medium of a coupling sleeve 26.
Normally acting to urge the piston |4 upwardly, and also the piston upwardly, is a spring 2| that is disposed about the stems l5 and I8, and engaged with the ends of the spring 2| are adjusting nuts 22 and 23, the former, nut 22, being screw-threadedly engaged with the outer end of the stem l5, and the latter, nut 23, being screwthreaded on the tubular extension l3a of the cylinder l3 as clearly shown in Figure 4. Obviously, through the medium of the nuts 22 and 23, the tension of spring 2| may be regulated as found desirable.
Threaded onto the bottom end of the cylinder I3 is a needle valve casing or block 24 having a tapered passage 25 extending therethrough and in which is adapted to seat a tapered needle valve 26 which, as clearly shown in Figure 7, is threaded onto the inner end of the piston stem or rod l8.
For the upper ends of the cylinders |2 there are provided caps 21 as shown.
A steam line 28 leading from any suitable source of supply is at one end connected with a manifold 29 that in turn is threaded into the caps 21 for supplying steam to the cylinders H2 in a manner to move the pistons l4 downwardly to engage the needle valves 26 with their respective seats 25. For controlling the supply of steam to the cylinders I2 there are provided in the ends of the manifold 29 suitable valves 30.
One of the valve devices, for example, the valve device I0, is adapted to be used for controlling the supply of steam to the burner and in this connection it will be noted that a steam line 3| leading from a suitable source of supply is connected at one end with one side of the valve block or casing 24 of the valve assembly In and is in communication with the passage 25 of said valve block.
From the valve block 24 of the valve assembly steam passes to the burner through steam' lines 3m and 3|b that are connected by piping 32 with said valve block 24 of the assembly ID at the lower end of the passage 25. In this connection it will be noted that the piping 32 is connected with the steam line 3| through the medium of a by-pass 33. Arranged in the by-pass 33 is a valve 34 while a valve 35 is arranged in the steam line 3| and valves 35a and 35b, respectively, are arranged in the lines 3|a and 3|b, respectively.
Substantially the same piping arrangement is associated with the valve assembly Illa for feeding oil to the burner, the oil line assembly including an oil pipe or conduit 36 leading from a suitable source of supply and connected at one end with one side of the valve block 24 of the valve assembly Illa. Oil conduits 36a, and 36b are connected with the valve block 24 of said assembly Illa through the medium of a piping 31 which latter is connected with the pipe 36 through the medium of a by-pass 38. Arranged in the line 36 is a valve 39 while arranged in the by-pass 38 is a valve 40. Also arranged in the line 36b is a valve 39a.
From the above it will be apparent that when the needle valves 26 are in open position, steam and oil in the proper proportions will be fed to the burner. When the steam generated in the boiler exceeds a predetermined amount, certain of the steam pressure will be utilized through the medium of the piping 28 for causing the pistons l4 to move downwardly to close the valves 26 thus shutting off, materially, the amount of steam and oil being supplied to the burner. With the valves 26 in closed position, the valves 35 and 39, and also the valves 34 and 40 are opened so that a small amount of steam and oil may be fed to the burner suificient to maintain a suflicient flame and preventing the fire or burner becoming completely extinguished.
Obviously, when the steam pressure in the boiler falls below a predetermined amount, the pistons M will move upwardly under action of the springs 2|, thus openingthe valves 28 when a greater volume of steam and oil, Ethan-per mitted to flow to the burner. It will be thus seen that thnough the medium of this device the iiow of oil or gas and steam to the'burner of the boiler will be automatically controlled and can be regulated as found desirable.
What is claimed is:
A fuel regulator for oil burners comprising, a pair of spaced cylinders, a piston in each cylinder, rods connecting said pistons, an adjusting nut on one of said rods, a coil spring encircling said rods, one end of said spring being adjustable with respect to the end of one of said cylinders the other end of said spring being in abutting relattm with said idjllltlll m, vaffimil inlet opening in theupper portion :0! one of said cylinders for communicating steam into said cylmder above the piston therein, a valve casing secured to the other cylinder having a tapered bore therein, communicating with a pair of spaced passages, and a tapered valve secured to the piston adjacent the valve casing movable in and (nit of said tapered bore for controlling a flow of fluid through said passages.
