' RELIEF-VALVE FOR HEATING SYSTEMS- Specification of Letters. Patent.
Eete d J ne 1.9,, 806-,
Application filed $eptember 1,1905- Serial No. 276 678.
To Ml whom it may concern:
Be it known that I, ARTHUR MoGoNAGLE, a citizen of the United States of America, and a resident of EastOrange, county of Essex, State of New Jersey, have invented certain new and useful Improvements in 7 Relief- Valves for Heating Systems, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
My invention relates to improvements in relief-valves for heating systems, and particularly to valves adapted for employment with steam-heating systems known as vacuum systems and operating under pressure loss than atmospheric pressure.
The main object of my invention is to provide a relief-valve of the simplest constructi on, so as to reduce to a minimum the liabil-' ity of its getting out of order and to render the parts readily accessible and easily interchangeable.
A further object is to reduce the cost of manufacture of such devices to a minimum.
In order that myinvention may be fully understood, I will nowdescribe an embodiment thereof in detail as illustrated in the accompanying drawings and will their point out the novel features in a claim.
In the drawings, Figure 1 is a view in cen-. tral transverse section of a relief-valve constructed in accordance with my invention. Fig. 2 is a detail top view-0f a portion of the casing, showing the valve-seat and the airpassage.
The casing as a whole comprises two parts, a body portion 1 and a removable cover 2. The body portion 1 has a discharge-opening 3, openin to a socket 4, internally screwthreaded for the reception of a pipe. This pipe in a vacuum system will lead to the exhausting apparatus, which may be a pump, e'ector, or similar device. also internally screw-threaded, constitutes an inlet to the said chamber and serves as means by which the valve as a whole may be connected to the radiator of a heating system or other part thereof, as may be desired. The cap 2 is screw-threaded into the body portion 1, as at 6, being preferably screwed down to a seat, so that a tight joint will be formed. The said cap has a cylindrical recess 7 arranged exactly opglosite the opening 3, axially in line therewit A valve 8 is fitted to the opening 3, being provided with a valve-stem 9 of a diameter substantially Another socket 5,
equal to the opening 3 The stem 9 is tubu A lar in form and extends at one end up into the cylindrical recess 7 and at the other end through the opening 3, so that the said stem extendsclear through the chamber 10, in closed by the casing.
fluid-pressure and will open freely upon the sli htest tendency to lift it, being kept closed on y by gravity. A float 11 is secured upon the stem 9 to serve to open the valve if water should collect in the casing.
In operation it will be seen that no matter how much difference ofpressure there may be upon opposite sides of thevalve, due to a lowering of pressure beneath the valve, as in a vacuum system, or a raising of pressure that air will pass in considerablequantities through an exceedingly minute space such as will practically excludethe passage of steam.
Water collecting in the casing will immedi- It will be seen by the foregoing that the valve 8 is balanced as. to
ately raise the valve by flotation, so that such water will be readily discharged. Thus the valve Will act as a relief for air and water,but will substantially hold back steam and prevent its exhaust.
A valve constructed in accordance with the above is exceedingly cheap to manufacture because of the little finishing that isrequired. It is only necessary to finish the valve-seat and the walls of the chamber 7 and the screw-thread connection 6 of theczising and then to finish the stem 9 and valve 8, all of said parts to be finished being cylindrical and so capable of being turned in a lathe. There are practically but twoparts to the whole device, the casing as a Whole being one part and the valve-stem and float being the other and the movable part. The parts are readily interchangeable, and there is no danger of the parts sticking, for all the parts work quitefreely and are entirely balanced.
What I claim is- In a valve of the class des(-ribed, the com- ICC binati'on with a casing-body and aremovable with a hollow tubular stem of substantially [0 cap or cover secured thereto, said casingl the same diameter as that of the opening and body having a discharge-opening With a of the recess, and extending upward into said valve-seat formed therein and provided with l recess, and a float secured to said stem, suban air-passage, and the cap having a cylinstantially as set forth.
