ORIFICE PROVIDED ELEMENT FiledJuneS, 1935 INVENTOR Patented July 2, 1935 UNITED STATES PATENT OFFICE ORIFICE-PROVIDED ELEMENT Delaware Application June 5, 1933, Serial No. 674,326
8' Claims.
This invention relates to orifice-provided elements.
More particularly, the invention comprises a hollow body provided with end openings and further provided with a lateralopening, a set of orilice-provided elements, the orifices of the respective elements being of different predetermined cross-sectional areas, and. retaining means for the selected orifice-provided element whereby upon insertion through the lateral opening and suitable positioning of the same within the hollow body, the orifice of the element effectually controls the fiow or rate of flow of fluid through the va ve.
Preferably, the orifice-provided element and its retaining means when arranged in position are concealed from tampering, to thus preclude disturbance of the same by unauthorized persons. Advantageously, such purpose is carried out by providing the lateral opening with a closure cap, which may serve also to seal the lateral opening against fluid leakage.
The retaining means, preferably, is provided with effective faces coacting with the orifice-provided element, which faces are contoured to engage inner face portions of the hollow body in substantial fluid-sealed relation therewith. The retaining means is advantageously formed to have retaining portions spaced from one another,
to provide a clearance of predetermined dimension, such clearance serving as a slot, each orilice-provided element having a thickness corresponding to such predetermined dimension to enable the element to be inserted in such slot and effectively held therein, the retaining portions respectively having an outer contour, thefaces of which substantially correspond to and engage abutting inner face portions of the hollow body, to preclude or minimize leakage of fluid thereat.
In the preferred forms of the invention, each orifice-provided element is further provided with an aperture, which conveniently is a perforation, at a portion thereof accessible within the lateral opening of the valve body, whereby upon removal of the closure cap, the orifice-provided element may be readily withdrawn by insertion of a suitable tool into such aperture and the application of force.
In the most preferred forms of the invention, the retaining member embodies a body portion to which the stated spaced retaining portions are integral or otherwise rigidly secured, the body portion beingprovided with a slot communicating with the slot of predetermined clearance, ,each orifice-provided element having an extension arranged to be inserted through the slot of the body portion, the hollow body being provided at its interior with annular formations, conveniently formed integral with the material of the valve, body, the material of the valve body being extended to partially fill the virtual bottom of the lateral opening. Such formations result effectively as or in the nature of a boss; these formations are spaced from one another within the bore of the hollow body and provide a slotted opening 10 accessible through the lateral opening and serves for the reception of the assembled orifice-provided element and its retaining means.-
Further features and objects of the invention will be more fully understood from the following detail description and the accompanying drawing, in which Fig. 1 is a central vertical section of an orifice valve embodying my invention; this view also illustrates the assembly of the orifice valve with p p Fig. 2 is a top plan view of Fig. 1, with the closure cap removed;
Fig. 3 is a vertical sectional view, on line 33- of Fig. 1;
Fig. 4 is a detail perspective view of a retaining member for retaining an orifice-provided ele ment;
Fig. 5 is a detail perspective view of one size of orifice-provided element;
Fig. 6 is a detail perspective view of another size of orifice-provided element; and
Fig. 7 is a detail perspective view of an orificeprovided element which is imperforate, that is, of nil size, serving as a shut off valve.
Referring to the drawing, the body ill of the valve is of any suitable construction, embodying end openings Ii, l2 and alateral opening l3. Usually, the end openings ll, l2 are in alignment with one another and the lateral opening I3 is- 40 normal to the end openings. Tubes or pipes I4, l5 are shown connected to the end openings II,
I2, respectively. Any suitable form of connec-' tion may be employed. In the illustrated embodiment such connection is had by a sweated 45 joint, that is to say, the inner faces of the end openings ll l2 are smooth and dimensioned with respect to the ends of the tubes or pipes l4, l5 to provide for capillary or surface flow of a suitable bonding medium, such as solder, which is 50 usually applied after heating the respective overlapping ortelescoped end portions, the solder upon cooling congealing to form a fluid tight joint of suflicient rigidity. The invention finds wideapplication in hot water heating systems and particularly with the use of copper piping. Accordingly, in such use,
Suitable orifice-provided means is disposed' within the hollow body of the valve through its lateral opening l3 for eifectually controlling the fiow of fluid through the hollow body. Advantageously, the orifice-provided element is in the form of a plate which is provided with an orifice of any predetermined or desired cross-sectional area. In the commercial practice of the invention, a set of plates is furnished having respectively orifices of diiferent sizes", for selection of the particular plate having the desired size of orifice, to eifect the desired regulation of the fluid fiow.
To accomplish such and other purposes, I prefer a retaining member I6 comprising essentially the retaining portions I60, I61; spaced from one another to provide a slot l 6b of predetermined clearance, to slidingly and frictionally receive and retain the selected orifice-provided plate, having an effective thickness corresponding to the dimension of the predetermined clearance.
A set of orifice-provided plates ll, [8, I9, etc., is illustrated in Figs. 5, 6 and 7. The orifice of the element I1 is indicated at Ila, see Fig. 5, and shown circular in configuration and of a diameter of predetermined size. The orifice of the element I8 is indicated at l8a, see Fig. 6, which is also shown as circular in configuration. As illustrated, the size of the orifice l8a is less than that of the orifice Ho. The element I9 is shown devoid of'an'orifice, see Fig. '7, in which instance,
the fiuid fiow is nil, that is to say, serving as a shut off valve, applicable under certain circumstances.
The respective spaced retaining portions "5a, [6a, are provided with openings l8e of an effective cross-sectional area greater than the cross-sectional area of the maximum orifice of the set of orifice-provided elements, to aiford eifective control of the fluid flow by the orifice of the selected orifice-provided element.
For effectiveness of assembly of the selected orifice-provided element and its retaining means is, and the ready insertion and the ready withdrawal of the assembly through the lateral opening I3, I provide within the longitudinal bore of the hollow body annular formations 20, 20, advantageously integral with the material of the hollow body, such formations including extensions 20a, 20a, see Fig. 2, at the region of intersection of the lateral opening with the longitudinal bore of the hollow body. Such formations result in the provision of the slotted opening 2 I, see Fig. 2, for the reception of the assembled selected orificeprovided. element and its retaining means. 'By dimensioning and contouring the retaining means It, in particular its portions Mic, with respect to the slotted opening 2| for making a tight frictional fit therein, the leakage of fluid between the mutually engaging faces is minimized and, if desired, substantially precluded. Nicety of frictional fit in contour and dimension is also made with respect to the mutually engaging faces between the lateral i. e. circular face of the body portion I60 of the retaining means 3 relative to the inner face of the bore of the lateral opening l3, to minimize or preclude possible leakage between the mutually engaging faces is'had by the provision of a closure cap 22, which may be provided with a gasket 23, see Figs. 1 and 3. The gasket 23 is preferably of annular configuration, as appears more fully hereinafter.
By the use of the closure cap 22 it serves also to conceal the orifice-selected element and normally precludes tampering by unauthorized persons.
For the ready insertion and withdrawal of the assembly of the selected orifice-provided element and its retaining means l6, each orifice-provided element, say I I, is provided with an upper extension Ilb having an aperture or other recess Ho, and combined therewith I provide the body Hie of the retaining means 5 with a centrally located slot lfid through which the extension I 7b is passed. Thus, such extension I'lb serves as a finger piece for effecting the insertion of the stated combined assembly, and by means of the aperture l 10 the combined assembly may be readily grasped and removed by means of a simple tool.
Such preferred form of the invention further embodies the advantage of affording pressure upon the orifice-provided element by engagement of its upper extension llb by the closure cap 22 upon tightening of the latter, and coincident with such purpose I provide the lower and lateral arcuate face, see lld, Fig. 5, of the orifice-provided.
element I! in this instance, to have a contour substantially precisely coincidental with the contour of the inner face of the bore of the hollow body It], as is indicated in Fig. 3. Corresponding parts of the remaining elements of the set of orifice-provided elements are designated by corresponding letter-sufiix reference characters, and function in similar manner.
The closure cap may be applied in any suitable manner, as by mating screw-threading as indicated, or by a friction fit cap, etc.
The element [9, see Fig. '7, conforming in out line to an orifice provided element, such as ll, [8, etc., but not embodying an orifice opening, may be employed for the purpose of complete restriction, that is, to shut-off the flow of the fluid.
My invention is applicable for all suitable systems providing for the flow of fluids of all character, including liquid, gas, and fiowable solids and the like; as specific illustrations, I cite hot water heating systems, water piping systems, refrigerating systems, domestic gas and other gas piping systems.
The advantages of my system are apparent from the herein disclosure. The requirement of individual orifice provided elements in sets respectively having different diameter or other dimensioned orifice openings, effects in practice substantial freedom from tampering by unauthorized persons. The absence of a valve stem or equivalent part accessible exteriorly of the valve body attains the object of concealment, tending toward discouragement of tampering. A look for the cap operated by key or otherwise may be employed if desired.
Whereas I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of the invention.
