The flanges 14 and 16 to- 95 stitution or adjustment, and which will be gether constitute a housing for the orifice composed of few parts which can be cheaply diskl as well/ as a connection for the pipe constructed and readily manipulated sections 10 and 12, and when the housing (itl is assembled, the contacting surfaces 32 of `the rims 28 and 30 determine the relative locations of the end faces 34 and 36 of the cylindricalfportions 18 and 20 of the flanges. Bolts 31 passing through the rims 28 and 30 secure the flanges 14 and 16 together The rims 28 and 30 on the lugs 24 and 26 are made relatively short so as to provide rectangular spaces 38 (Fig. 1) at each sit e of the housing of sufficient length to permit an orifice disk to be readily inserted or removed through them.

'lhe end face 36 of the cylindrical portion 2O of the flange 16 is rabbetted on its inner edge as indicated at 40 (Fig. 3) to provide clearance between the orifice disk and such portion of thc face. and interposed between the outer unrabbetted portion of the face 36 and the orifice disk 22 is -a gasket 42. The gasket 42 may be relatively thin and may be readily cut without the use of special tools from a sheet of suitable material. It has been ascertained by actual use of the invention that the gasket 42 is not required to possess any considerable degree of elastieity or compressibility so that the material of which it is composed may be comparatively inexpensive. The gasket herein illustrated is made from sheet packing of the character known to the trade as Permanite. For convenience in assembling the parts. the gasket 42 may be placed in proper position on the disk before it is inserted into the housing, and may be caused to adhere to the disk by shellac or other suitable material. The gasket 42 is also preferably coated with graphite on its right hand surface where it contacts with the cylindrical portion 20 of the flange 16.

Surrounding the cylindrical portion 18 of the flange 14 is a rubber packing ring 44, which by reason .of the reduced exterior diameter of the portion 18 with relation to the portion 20 of the flange 16 is of substantiallyA equal dian'ieter to the gasket 42. lVith this construction. when an orifice disk 22 is inserted in the housing, the gasket 42 and rubber packing ring 44 engage it at directly opposite points. f

A, ring 46, which may conveniently be termeda pressure ring, encloses the cylindrical portion 18 at the rear of the packing ring 44. The ring 46 is turned outwardly atits rear end to form a rib 48, and abutting against the rib 48 are a series of six screws 50 threaded into the flange 14. Surrounding the pressure ring 46 and the packing ring 44 is a third ring 52 which is hereinafter sometimes referred to as a retaining ring inasmuch as it prevents the packing ring 44 from being squeezed outwardly and retains it in close engagement with the pe riphery of the portion 18 of the flange 14, thereby precluding any escape of fluidV between the packing ring and said portion.

From the foregoing, it will be understood that by turning the screws 50, the pressure ring 4,6 may be forced toward the orifice disk 22 so as to clamp the gasket 42, orifice disk '22, and rubber packing ring 44 between the pressure ring 46 and the flange 16. In this manner, a fluid-tight connection is formed between the orifice disk 22 and each of the flanges 14 and 1G.

lVhen an orifice disk is inserted in the housing. the retaining ring 52 is preferably moved into close engagement with it. In this position of the parts, the packing ring 44 is positively supported at all points so that all possibility of the ring becoming distorted is eliminated. As shown, screws 54 are provided on the flange 14 for moving the retaining ring 52 and maintaining it against the orifice disk.

In order to facilitate the formation of fluid-tight connections about the orifice disk 22, the space between the end surfaces 34 and 36 of the cylindrical portions 18 and 20 of the flanges is of such size only as will enable the orifice disk and the gasket 42 to be readily inserted between them. The orifice disk is made quite thin, and the gasket 42 is also thin to avoid the' use of unnecessary material. To the end that the packing ring.r 44 may have suflicient body to make it durable and to enable it to form a fluid-tight connection between the orifice disk and the flange 14, it is constructed of considerable breadth and of a thickness greater than the combined thicknesses of the orifice disk 22 and gasket 42. In the illustrated construction the orifice disk 22 and gasket 42 have thicknesses of one-fourth and one-sixteenth inches respectively` and the packing ring 44 is made square in cross-section with a breadth 'and thickness of one-half` inch.

After the orifice disk housing has been assembled and installed in a pipe line, it is very desirable that the flanges 14 and 16 should not be required to be separated while the housing continues -in use. The packing ring, 44, however, deteriorates with continued use, and it is necessary'from time to time to substitute a new packing ring for it. In order that a new ring may be substituted without changing the relation of the flanges 14 and 16, the packing ring 44 is made in sections, each of which has a thickness not appreciably greater than the combined thicknesses of the orifice disk 22 and gasket 42. As shown, the packing ring is composed of two sections. each of which has a breadth of one-half inch and a thickness of substantially one-fourth inch.

In assembling the parts of the housing` the flanges 14 and 16 are first'. screwed on to the pipes to he connected, after which the pressure ring 46 is placed over the cylindrical portion 18 of the flange 14. and the rctaining ring 52 is slid into Place over th@ ring 4G. The fianges l-f and 16 are then bolted together. The sections of the packing ring 44 may then be passed one at a time through the orifice disk gap and seated against the pressure ring 46, which together with the ring 52'is pushed to the left (Fig. 3) away from the flange 16. The orifice disk Q2 and gasket t2- are next inserted, after which the ring 52 is forced into contact.` with the orifice plate by means of the screws 54. The assembly of the device is completed by tightening the screws 50 to compress the packing ring 44 and gasket 42 between the orificedisk and the pressure ring -16 and flange 16 respectively.

lith the illustrated construction, the insertion, removal or adjustment of an orifice disk can be very readily accomplised, inasunich as it requires only the tightening or loosening of the screws 50 and 54. Moreover, fluid-tight connections are provided between the. orifice disk and the flanges by the use of` a single rubber packing ring, pressure ring, and retaining ring. It is important that the number of rubber packing rings used shall be as small as possible since they are relatively expensive as compared, for example, with the gasket 42. rl`he cost of the illustrated construction is also kept down by' reason of the small number of its parts.

Althoughthe plate 22 in which the orifice is provided is referred to herein as a disk, it is manifest that the invention may be utilized in connection with .orifice plates of various forms.
