Numerous devices have heretofore been proposed for regulating the water supply, but these have not proven entirely satisfactory in the regulation thereof over extended periods in that the instrumentalities were subjected to the intense temperatures of the system with which they Were associated, thereby being soon rendered inoperative or at least unsatisfactory.'
It is generally recognized that the water level in boilers should be maintained constant in order to insure the highest possible efficiency as Well as preclude injury to the boiler occasioned by the total or partial absence of water. ater usually constitutes the heat carrying medium or in other systems in the form of steam conveys heat or energy for any desired purpose. In view thereof, it is essential or at least highly desirable that the quantity of water be maintained substantially constant to render the absorption of heat from the combustion chamber most efficacious.
One object of the present invention is to simplify the construction and improve the operation of devices of the character mentioned.
40 Another object is the provision of an automatically operable valve disposed remote from confines subjected to elevated tempera tures.
Still another object is the provision of a water system which is subjected to boiler pressure to enable the introduction of water without auxiliary injecting means.
A further object is the provision of an automatically operable valve which is jacketed by the water supply which eflects the coolciate'd from the confines of the supply tank 'ing thereof and, simultaneously constitutes the control means therefor.
A still further object is the provision of a float operated valve which is remotely assoin order to insure the operation thereof.
Still a further object is the provision of a water supply system for boilers wherein the pressure thereof is exposed to the system to reduce the water supply pressure necessary to effect the introduction thereof.
Other objects and advantages will appear from the following description of an illustrative embodiment of the present invention.
In the drawing:
Figure 1 is a fragmentary sectional view in elevation of a device embodying features of the present invention. j l
Figure 2 is a plan view of the water regulating instrumentalities with the cover there-, of removed to clarify the showing.
The structure selected for illustration is shown in association with a steam boiler 10 of standard construction, although other forms of boilers are equally susceptible for. such adaptation including hot waterboilers which are generally low pressure heat generators. V
A water supply tank 11 is supported on a suitable standard 12 adj acent the boiler 10, in proximity to the top thereof in order to" constitute a water reservoir therefor. The tank 11 has a closure'13 which is maintained steam tight in association therewith by means of fasteners 14 of standard construc-, tion. Water 15 in the tank 11 isin communciation with the water 16 confined within the boiler 10 through a conduit 17 which is disposed in proximity of the bottom of the tank 11.
the steam pressure within the boiler 10. This is highly advantageous from a standpoint of commercial economy in that standard injectors or pumping instrumentalities are not necessary, for the pressure in the water main is sufficient to effect its introduction within the boiler via the tank 11.
Valve means'are employed to control the introduction of the water 15 within the tank 10, there being provided a cylindrical valve body 20 having a peripheral flange 21 thereon for securing it to the bottom ofthe tank 11 in communication therewith by means of the studs 22. The valve body 20 terminates in an end facev 23 having an axial bore 24 therein to slidably receive a valve stem 25 therethrough. 1 Ports 26 are provided in the valve body 20-within the tank 11 to admit water thereto. The valve body 20 terminates in an interiorly threaded mouth portion 26 which detachably receives a threaded valve seat body 27-having ports 28 provided therein forest'ablishing circulation from a suitable water supply source to the tank 11. 'A valve 29 shaped to conform with the seat 27 is secured to the valve stem 25 and maintained in fixed position thereon by means of a peripheral shoulder 30 which cooperates with a nut 31 in threaded engagement with the threaded portion 32 of the stem 25. It is to be noted that the stem 25 has a reduced portion 33 at the extremity thereof which reciprocateswithin an axial apertures 34 provided in the valve seat casing 27 to guide the valve stem 25 vertically.
The position of the valve 29 with respect to its seat 27 is controlled by means of a float 35 of standard construction which is carried by an arm 36 having the free extremity thereof pivoted to the tank 11 at 37, there being a link 38 pivoted thereto as at'38 to actuate a lever 39 operatively connected therewith. The lever 39 is pivotally carried by a bracket 40 to impart movement to a toggle 41 which is in rigid association with a member 42'to effect the elevation or descension thereof. The member 42 which is pivoted to a lug 42 engages a boss 43 which is suitably associated with the extremity of the valve stem 25 so as to impart movement thereto responsive to motion of the float 35 occasioned-by a vari-v ance in the level of the water 15 which effects the control thereof. The linkage constituting the operative connection between the float 35 and the valve rod 25 is of the toggletype which is productive of the desired purchase for controllingthe position of the valve 29 so that slight variations in water level will operate the valve 29 to supply the necessary water, to maintain aconstant supply therein.
In order to protect the valve 29 and its as sociated parts from the effect of the high temperature prevalent in the tank 11, a casing 45 having a closed end 46 is positioned concentrically of the valve body. The casing 45 has temperature regions. chamber 26 may be so arranged as to further to the interior of the valve body 20. With the valve 29 in its closed position, the conduit 49 constitutes an outlet which returns the water to the supplysource so that a constant pressure is maintained within the casing 45 which surrounds the valve body 20 to constitute a water jacket therefor. Obviously this serves to maintain the valve instrumentalities atra decreased temperature to preclude warping or other injury thereto occasioned by elevated temperatures prevalent within the tank 11.
The water level in the boiler is maintained" constant by means of the float 35 which is 'operatively connected with the valve 29 to govern the position thereof withreference to its valve seat 27. The lowering of the level of the water 16 within the boiler 10. will" cause the float 35 to descend, thereby removing the valve 29 from its seat 27 to admit water within the valve body 20 through the ports 26 for passage to the tank 11 which supplies water to. the boiler 10 through the conduit 17.
Withthe arrangement of parts above descr bed it will be apparent that a simple and effective device has been provided to maintain. a constant water level within heat gencrating apparatus, thereby insuring safe operation, high efficiency and low cost of maintenance.
