STEAM HEATlNG SYSTEM.
SPECIFICATION forming part of Letters Patent No. 391,4.15, dated October 23, 1888.
Application filed September 4, 1885. Serial No. 176,194. (No model.) I
To all whom, it may concern.-
Be it known that I, TIMOTHY J. KIELEY, of the city, county, and State of New York, have invented a new and useful Improvement in Steam-Heating Systems, ofwhich the following is a full, true, and exact description, reference being bad to the accompanying drawings.
This invention relates to an improved apparatus by means of which the water is automatically returned to the boiler from a steamheating system and the level of the water in the boiler constantly maintained. By this system, likewise, the effect known as hammering in the pipes is to a great degree prevented. That which is new in my invention will be found specified in the claims annexed to this specification.
My invention will be readily understood from the accompanying drawings, in which Figure 1 represents a view of my entire system; Fig. 2, a detailed view of the pump-regulating governor.
A represents the boiler or source of steam. The steam from this boiler passes through the main steam-pipe F to the different parts of the heating system. For instance, the radiator E and the box-coils E E are connected with such main steam-supply in this pipe. AtTis placed a pressure-regulating valve ofone of the known forms, which determines the pressure existing beyond it in the system. The returns from the heating-coils connect with a main returnpipe, N. Such connections are shown at M and O. In some pipe connecting the steamsupply and the return distant from the boiler I locate a water-gage, V, for a purpose hereinafter to be determined. The inainreturn-pipe connects with a pump-governor, O, which may be of any known form, though I prefer the form shown in Fig. 2. The connection is made through the single pipe N.
It will be readily seen that the single connec tion thus shown performs a valuable function over two connections in the following particular; If a connection entered the pump-governor chamber and the water passed into that pump-governor chamber through said connection and left it through another, there would necessarily be a continued flow of the water of condensation through that pump-governor, whereas by the single connection shown the water will fall and rise in the pump-governor without substantially changing. By means of the single connection shown I am enabled to maintain the pump'governor at a higher temperature than would otherwise be possible, and to avoid the continual change of water above referred to. The object of this pump governor is to determine the action of a pump by the water'supply to the same. The main returupipawhich connects with the pump D, as shown, connects likewise through the pipe N with the pump-governor. This p unip-governor contains a float,and is connected with a stealnvalve in the pipe G, so that when the Water rises above a certain level in this pumpgovernor the steam-pump will commence to operate, thereby forcing the water back to the boiler through the pipe WV. Connecting with the main steam-pipe and with the top of the pump-governor is the pipe H, which equalizes the pressure in the pump-governor. The result of this combination is that the water will continually stand in the bottom of the system at about the line w x, which prevents the steam from working around back into the radiators by coming down through the connecting-pipe of some other radiator. To this cause is principally due the effect of pound ing or hammering in the radiators previously referred to. Connecting likewise with the pump-supply is the pipe P, which is connected with the main water-supply to the boiler. In this pipe is the valve R,coutrolled by the boiler-governor B. This boiler-governor has a float, which, when the boiler-governoris empty of water, causes the valve R to open at its doscent, thereby supplying an additional amount of cold water to the pump, which may at that time be operating under the control of the pump-governor. Under these circumstances an additional supply of water will be returned to the boiler in case the pressure in the supply is greater than the pressure in the system. As is generally the case, the inflow of water through the pipe P will set the pump-governor in operation and cause the pump to operate to return the water to the boiler.
The boiler-governor is caused to operate by reason of its connection with the boiler by the pipes S and S. The bottom of the pipe S dips to the point in the boiler where it is de- ICO sired to hold the water-level. When the water-level is above the lower end of the pipe S, the boiler-governor will be filled with water and the pipe R closed. If, however, the water drops below this level, the Water will also fall out of the boiler-governor and the valve R will be opened.
In some cases I do not employ the pumpgovernor, but operate the pump by hand. Under these circumstances the engineer, by observing the height of the water in the waterglass V, can determine the height of the seal which he desires to keep in the bottom of the system.
It will be observed that the water-glass bis placed in a connection connecting the main steam and return pipes beyond the connection from the radiators nearest to the boiler. This distant water-gage I consider important, as enabling the engineer to regulate his pumpgovernor by the height of the water at a point distant from the more immediate returns. I find in practice that the distant water-level may be different from that nearer the pumpgovernor, and it is important for the engineer to regulate the pump-governor by the most distant water-level.
What I claim as my invention, and desireto secure by Letters Patent, is-
1. The combination, in a steamheating sys tem, of a main steam-supply pipe having a regulatingvalve therein which automatically governs the main steam-supply pressure, the main return-pipe, the return-pipes from the heating-coils communicating with the said main return-pipe, a pump-governor independent of the main steam-supply, a pump controlled by the said governor, and a stearnconnection between the main steam-supply pipe on the low-pressure side of the regulatingvalve and the pump-governor, the said connection forming the single connection between the main steam -supply and the pump-governor, substantially as described.
./2. The combination, in a steam-heating system,of a main steam'supply pipe having a regulating-valve therein which automatically governs the main steam-supply pressure, the rat diators, the main return-pipe, the return-pipes between the radiators and the main returnpipe, a pipe distant from the boiler connect-- ing the steam-supply pipe with the main return-pipe, a gage, V, in the last said pipe, a pump governor independent of the main steam'supply, a pump controlled by the said governor, .and a steam-connection between the main steam-supply pipe on the low-pressure side of the regulating-valve and the pump-governor, the said connection forming the single connection between the main steam supply and the pump-governor, substantially as described.
3. The combination, in a steam-heating system, of a boiler provided with a boiler-gov ernor and main steam-pipe leading from said boiler, having therein a regulating-valve regulating the pressure of the steam-supply to the system, apump-governor, apump,and asteamconnection for operating said pump, a connection between the water-supply and the suction of the pump, and a valve in said connection operated by the boiler-governor, and a connecting-rod connecting said water-valve with the operative parts of the boiler-governor,substantially as described.
4. The combination of a boiler and main steam supply pipe and regulating valve placed therein, and steam heating system supplied from said pipe, and main steam-return, and steam-pump returning the water from said return to the boiler, and pump-governor regulating said pump, the said pump-governor being connected with the return by one connection only, thereby enabling substantially the same water to remain in the pumpgovernor, and an equalizingpipe between the pump-governor and the main steam-supply system beyond the equalizingvalve, substantially as described.
