Description
Patented Nov. 22, 1938 UNITED STATES PATENT OFFICE NIPPLE ORIFICE ration of Illinois Application March 8, 1937, Serial No. 129,678
2 Claims.
This invention relates to nipple orifice elements for use in reducing the flow oi steam, for example, to steam heating appliances.
The purpose of this invention is to provide a flexible orifice element for convenience oi application thereof to irregular hollow forms such as some radiators wherein the casting of the first unit of the radiator is of such form that a straight, rigid orifice tube cannot be conveniently applied.
The object of the invention is accomplished by means of construction as illustrated in the drawing.
Figure 1 of the drawing shows in elevation the orifice element and in section a fragment cf a radiator to which the element is attached.
Figure 2 is a perspective View of a perforated flow-restricting capvused in the construction illustrated by Fig. 1.
In steam heating systems, for the purpose of reducing the iiow of steam to one radiator relative to others resort is frequently made to various types of orice elements, in addition to other flow or temperature regulating means. For example, these devices are used when it is desired for some reason to reduce the heat output of some particular radiator or perhaps sometimes to increase its output, in case there is an orice element therein which unduly restricts the flow of steam to the radiator. The nipple or tubular type of orice element is particularly desirable when the steam supply enters at the bottom of the radiator and it is necessary to have the orifice above the level of water which may collect where the steam conduit is connected with the radiator. Some radiator castings are of such irregular form that it is not practical to use a rigid tube carried by screw ttings. In order to overcome this difficulty and to provide an oriiice element which maybe applied with ease, applicant has provided the one herein described.
The orifice element includes a support in the form of a threaded nipple for fitting a radiator bushing. Sweated to the inside of the nipple is a flexible metallic tube, the free end of which has Sweated thereover an orifice cap. These caps are made with numerous standard sizes of outlet perforations so as to meet any requirement with reference to steam pressure and the desired restricted ow.
As shown in the drawing, the three parts of the orifice element are a perforated cap I, iex- 10 ible steam tube 2, and the threaded fitting 3, in which one end of the tube is sweated or otherwise rigidly secured. The cap l is also permanently sweated into place.
When the element is applied to an irregular 15 form such as the radiator section illustrated, the tube may flex when the tting 3 with which it is rigidly connected is turned into the bushing 4. Replacements of the orice element may likewise be made without difficulty. This con- 20 struction also brings the orice above the level of water which may collect in the space 5 of the radiator casting 6.
I claim:
1. A steam radiator having a steam inlet open- 25 ing with an orice element secured to the radiator at said opening and comprising a hollow supporting and attaching member having extending therefrom a flexible tubular member, and carrying at its end away from the support a 30 perforated iiow restricting element.
2. A steam radiator having a steam inlet opening at its bottom and a tubular flexible flow restricting means attached to the radiator at said opening and extending upwardly therefrom to 35 reach above a normal condensate level in the radiator, and constructed to include a denite iiow restriction means with an opening therein of less diameter than the internal diameter of the flexible tube.
