AUTOMATIC REGULATING-VALVE.
Specification of Letters Patent.
Patented Dec. 8, 1914.
Application filed June 2, 1913. Serial No. 771,230.
To all whom it may concern:
Be it known that I, DENIS DENNEHY, a citizen of the United States of America, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Regulating-Valves, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to automatic regulating valves and more particularly to the class of valves designed for hot-water heating systems. It is awell known fact that an expansion tank is used in connection with such systems to receive hot water in excess of what is necessary to properly maintain the system, and it is between such a tank and the hot-water boiler that I interpose the valve to regulate and govern the pressure of hot water throughout the system.
The object of my invention is to provide a simple, durable and inexpensive valve of the above type having positive and reliable means, in a manner as hereinafter set forth, for allowing an excessive pressure of hot water to escape to an expansion tank and permitting the water to return to the system when the pressure has been restored to normal.
WVith the above and other objects in view the invention resides in the novel construction, combination and arrangementof parts to be hereinafter specifically described and then claimed.
Reference will now be had to the drawing, wherein Figure 1 is a vertical sectional view of a valve in accordance with this invention, Fig. 2 is a plan of the same, Fig. 3 is a horizontal sectional view taken on the line IIIIII of Fig. 1, and Fig. 4 is a similar view taken on the line IV-IV of Fig. 1.
A valve in accordance with this invention comprises a cylindrical or tubular body or casing 1 having its upper and lower ends provided with annular flanges 2 and 3. Connected to the flange 2 by a plurality of screw bolts 4 is an upper horizontal partition 5 having a boss 6 fittin in the upper end of the valve body. This oss has a central cylindrical recess 7 and the partition 5 is formed with a central opening 8 in communication with said recess. Connected to the partition 5 by diametrically opposed screw bolts 9 is the annular flange 10 of a cap 11, said flange having openings 12 providing clearance for the screw bolts4. Connected to the annular flange 3 by a plurality ofscrew bolts 13 is a lower horizontal partition 14 having a central opening 15 and a depending side boss 16, said side boss having an angle port 17 formed therein. Connected to the partition 14 by screw bolts 18 is the annular flange 19 of a chamber 20, said flange having openings 21 providing clearance for the screw bolts 18. The bottom of the chamber has a nipple 22 adapted to be connected to a hot water supply pipe located between a hot-water boiler and an ex pansion tank. Located within the chamber 20 is a strainer or perforated disk 23 supported in a superimposed position relatively to the nipple 22 by an annular flange 24. The strainer is held against vertical displacement by uprights 25 engaging the lower side of the partition 14. This strainer prevents solid matter from being carried into the valve body 1. Connected to the boss 16 is a goose-neck 26 having a check valve 27 of the ordinary and well known type, said check valve preventing water from flowing into the goose-neck from the chamber but allow ing water to flow into the latter from above the partition 14. Normally seated upon the partition 14 and closing the opening 15 is a cup-shaped valve 28 capable of vertical movement between inwardly projecting lugs 29 carried by the walls of the valve body 1. The valve 28 has a central post 30 and movably mounted in the post is the depending stem 31 of a lower spring socket 32. The latter is movably mounted in an upper spring socket 33, which has ribs 34 spacing it from the walls of the valve body 1. Arranged within the sockets 32 and 33 is a coiled compression spring 35 which holds the lower spring socket 32 upon the post 30 and the valve 28 seated upon the partition 14.
The top of the upper spring socket 33 is provided with an interiorly threaded vertical sleeve 36 that extends into the recess 7 of the boss 6 and is guided by .the walls of said recess. The sleeve 36 is moved within the recess 7 by a screw rod 38 the upper end of which extends through the opening 8 of the partition 5 and through a stufiing box 39 which is secured to the partition 5 by screw bolts 40 or other fastening means. The rod 38 has a collar 41 within the stufling box to prevent vertical dis lacement of said stem. The upper end of t e rod within the cap 11 has a hand wheel 42, whereby the screw can be adjusted to raise and lower the upper spring socket 33 and'thereby decrease or increase the tension of the spring 35.
The valve body 1 has the wall thereof provided with an outlet opening 43 adapted to' be placed in communication with an expansion tank (not shown). The opening 43 is located above the upper spring socket 33 and in proximity to the boss 6.
In operation, an excessive pressure of hot Water passes upwardly into the chamber 20, elevates the valve 28 and passes around the upper and lower spring sockets to pass through the opening 43 to the expansion tank. The tension of thespring 35 can be regulated whereby it will require a predetermined pressure to elevate the valve 28. As the pressurebecomes normal the valve 28 is gradually seated closing the opening 15. The water that has accumulated within the expansion tank, the valve body 1 and connections with said body can then drain through the angle port 17 into the chamber 20 and return to the source of supply. The accumulated water. will flow into pipe 26 from a circumferential channel formed between the wall of casing body 1 and the cylindrical Wall of valve 28. When this valve is seated the channel formed between it and the casing will have but one outlet,
namely, through the port 17 which opens into the bottom of the channel at one side of; the casing. By this means I am enabled to insure proper drainage.
From the foregoing it will be observed that I; have devised a novel safety valvewhioh is also-applicable for steam and gas purposes and that the exhaust of the valve can be readily controlled by regulating the Copies of this patent may be obtained for tension of the spring 35. I attach considerableimportance to the fact that the spring One embodiment of the invention has been illustrated, but it is to be understood that the'structural elements are susceptible to such variations andfm'odificationsas fall within the scope o-f-the appende'd'claim.
An automatic regulating valve comprisinga casing'op'en at its ends and having an outlet in' one side partitions at'the'ends of said casing, one of said partitions having an opening therein forming" a"fli 1i d inlet, and the other paiftition'having a centrally disposed recess forming a g'uid eway, a valve for closing said inlet opening, telescopic members arranged 'saidca'sin a spring inclosed bysaid. members,'one of t he latter being designed to control the "movement of said valve, and the 'other' member having an interiorly threaded sleeve fitting sa d guideway, and a"'s crew working 111 sa1d sleeve for adjusting" saiddast mentioned member" to regulate! the" tension of said spring. I
In testimony whereof I afiixmy signature in the presence of two witnesses.
