out the pump being stopped, a circulation through the pump will be maintained and overheating of the pump thereby avoided. In the operation of high pressure centrifugal pumps, it frequently happens that, although the pump the water or other liquid 1s not being drawn from the discharge side of the ump and the impeller rotates at such high speed that the inert water within the pump is heated and lmay be converted into steam. Unless some escape for this steam or heated water is provided, the pump becomes overheatedand its operat'on and durability is seriously adversely affected. The present invention provides a very simple device whereby this overheating will be avoided.
In the accompanying drawing,
Fig. 1 is a view in the nature of a diagram` showing one embodiment of the invention,
Fig. 2 is an enlarged section through the relief valve and its connections.
, In the drawing, the reference numeral 1 indicates a high power pump having three stages and 2 designates an electric motor for driving the pump, these parts being of well known construction and being illustrated conventionally. At 3, there is conventionally indicated a vflow meter which is' operated by the outiow from the .pump and is welllmown equipment. In carrying out the present invention, there is provided a'valve casing 4 which is substantially spherical in form and has an inlet port in its bottom in direct alinement with a coupling tube or pipe 5 which is secured in the pump casing, at the high stage chamber of the same, so as to communicate therewith. casin 4, there is an outlet port in which is threa ed one end of an outlet pipe 6- which has its outer end coupled to a discharge pipe 7 which may dischargev into the open air or ma be connected with the pipe line which is ed by the pump. The top or upper side of the valve casing 4 with a reduced externally threaded neck defining an annular stop shoulder, as shown vagainst said stop shoulder, the
clearlyv in Fig. 2, and a bonnet 8 is threaded on said neck, over said opening and bears upper end of the bonnet being enlarged and extended verticallf to provide a housing 9 in which iS secure an electro-magnet 10. A. cap 11 may be secured upon the upper end of the housing 8 to prevent the entrance of foreign matter and to-protect the electro-magnet from elements which might tend to cause its deterioration. A guide plug 12 is secured in the bonnet 8 and slidably fitted through said plug is a valve stem 13 having a valve 14 at its lower end adapted to seat inthe inlet port y of the valve casing, as shown 1n Fig. 2, an expansion spring 15 being coiled around the stem between the valve the plug 12 so as to normally hold the valve seated'. The plug l12 is threaded into the bonnet 8 and it is obvious that by pro erly manipulating the plug, the tension oi) the sprin 15 may be easily regulated. In practice, -t e sprin will be put under a tension greater than t e pressure normally existing withinthe third stage of the pump so that the valve will be held seated under all normal and the lower end of' conditions. The upper portion of the valve stem 13 passes through a stuing box 16 fitted. 1n the upper end of the guide plug 12 and, at its upper end, the stem carries a head or disk- 17 which constitutes the armature for I the electro-magnet. One terminal 'of the electro-magnet merges into a conductor 18 which leads to a battery or other source of From the opposite side of the indicator arm 21 of the ilow meter. The other terminal of the electromagnet winding merges into a conductor 22 which extendsto a contact 23 set in the indicator board 24 of the iow meter and cooper-Q ating with a contact 25 carried by the indi-` cator arm. p p
As long as there is a properdischar of water from the pump, the valve 14 be seated so that the valve casing will vbe closed to iow from the pump and the indicator arm 21 will be at some point spaced trom the zero ppint of the How meter.- When the outow om the discharge port of the pump, or
A the casln neck de armature for the ma v net the indicator arm, the contacts 23 and 25 will be in engagement and, conseuently, the electro-magnet will be the armature 17 of the spring 15, so that the valve le will be opened and the highly heated Water or steam Within the chambers of the pump will be permitted to escape through the pipes 5, 6 and 7.
en the normal conditions are restored in the pump, the indicator arm of the flow meter will leave the zero point thereof so that the circuit throu h the electro-magnet will be broken and t e valve 14 will then be seated under the induence of the spring l5.
It will thus be seen that I have provided an exceedingly simple and compact arrangement which will operate automatically to ren lieve the heated conditions in a pump so that overheating of the pump will be avoided. The device comprises few parts so that it is not apt to get out of order, and the cost of maintenance will be negligible.
Having thus described the invention, I claim,
energize and will draw lpg a substantially spherical casing having an i et in its bottom and having its up er portion reduced to form an externally threaded neck defining an annular stop shoulder, a bonnet engaging the threads on the neck and bearing against said stop shoulder, the upper end of the bonnet being enlarged to form a housing, an outlet leadlng from one side of a valve within the casing seated in the in the bonnet, a stem rising from the valve and passing loosely through said plu an expansion spring coiled about the stem tween the plu and valve, an electro-magnet disposed wit in the housing, and a disk on the upper end of the valve stem and constituting an 2. A device of the class described comprising a substantially spherical casing having an inlet in its bottom and having its up er portion reduced to form an externall t readed4 g an annular stop s oulder, a bonnet engaging the threads on the bearing against said stop shoulder, said bonbeing provided with an intermediate reduced portion and having its upper end enlarged to form a housing, an outlet leading `from one side of the casing, a valve within the casing seating `in said inlet, a plug threaded in the reduced' portion of the bonnet and provided with a seat, a gland disposed in said seat, a stem rising from the valve and passing through said plug and gland, a sprin coile about the stem between the lower en of the plug and said valve, an electro-magnet disneck and osed within the housing, and
