ARCHIBALD H. DAVIS, .13., OF BUFFALO, NEW YORK, A SSIGNOB, TO NATIONAL ANILINE AND CHEMICAL 00., IN (3., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
VALVE HEATER.
Application filed November 10, 1925. Serial No. 88,148.
2 freeze at ordinary temperatures, heat'needs tobe applied as well to the valves controlling the flow of material to keep the material from freezing to the valve elements. However, as such valves are protected with heat insulation, it becomes necessary to apply the heat within the heat insulating jacket.
An object of this invention is a provision of means for heating a valve within the insutached heater;
lating jacket. Another object is such a heating means that may be readily removed and replaced without disturbing the valve or the jacket. These and-other objects will appear from the description which follows.
In the drawing" Fig. 1 is an end view'ofa valve showing the heating means attached thereto;
Fig. 2 is a side view of the valve and the at- Fig. 3 is a partial View of the other end of the valve; and
Fig. 1 is a detail.
The valve body 1 has integrally united or welded to it, or otherwise secured, a steel tube 2. The tube is of a size to properly a'ccommodate a cartridge type electric heating unit 3, and it is-of such a length that it extends beyond the limits of the magnesia or other heat insulation applied to the valve. One end of the tube is closed by a removable plug 4, held in place by a cotter pin 5. To the other end of the tube is secured, as by welding a pipe 6, which forms a continuation of the tube, and in it are assembled a suflicient number of insulating beads 7 to fill its length. Wires 8, passing through perforations in the beads connect with the cartridge 3.
The pipe 6 is connected by a union 9 to a conduit system 10. A condulet 11., in the conduit system and in alignment with the pipe 6, has a removable cover 12. The leads 8 from the cartridge 3 are attached to contact plates 13 and 14 on the condulet body, and contact plates 13 and 15 are in electrical connection with the conduit systems at points 16, 17 On the cover there are two contacts 1.8 and 19 and a fuse Wire 20 connecting them. When the cover is in place, the contacts 19 and 15 form one connected pair, and the contacts 18 and 14 form another connected pair; current then flows from connection 16 to contact 13 through the leads 8 and cartridge 3 to the contact 14, contact 18, fusewire 20 to contact 19, contact 15 and connection 17.
When it is-desired to replace a cartridge, the plug 4 and the cover 12 are removed. The cartridge leads are disconnected and the cartridge can then be withdrawn or pushed out of the tube, as both ends ofthe tube are accessible.
While the invention primarily contemplates electric heating, it is evident that other heating means may be used. For instance, the cartridgecan be a solid having a high specifie heat and preheated before insertion in the tubeto give oif heat to the valve; or it can be a combustible substance generating heat. Where gas or other combustible fluid is available a burner can be arranged in connection with the tube to pass hot gases of combustion through the tube. However, the electric heating unit of the cartridge type is preferred as it requires no attention beyond replacement; and, as it is enclosed by the heat insulation, the heat is conserved for the useful heating of the valve.
By the term valve is to be understood any flow controlling body, such a cock, check valve or the like; and the term is used in this inclusive sense in the claims. Furthermore, by the statement that the tube is welded or otherwise secured to the body, it is intended to include an integrally cast tube' as well as a separate tube.
