Filed:

Jun 18, 1990

Appl. No.:

7/539229

Inventors:

Fred W. Hendrick - Cerritos CA

Assignee:

Automatic Control Components - Boulder CO

International Classification:

F16K 308
F16K 11074

US Classification:

13762531

Abstract:

To reduce the torque required to turn a movable upstream disk relative to an abutting stationary downstream disk in a multiple orifice valve, particularly when the disks are subjected to high fluid pressures, there is provided a removable sleeve or insert at the outlet side of the stationary downstream disk having a support member formed therein for supporting the downstream or outlet side of the downstream disk. The support member may be provided with a central raised portion for supporting the downstream side of the stationary downstream disk along the central axis thereof which is coaxial with the central rotational axis of the movable upstream disk. The supportive sleeve or insert serves to reduce the torque required to turn the upstream disk irrespective of the diameter of the disks. Such a sleeve further reduces the required turning torque in such valve assemblies wherein the abutting faces of the disks are polished to a high level of surface finish quality. In yet a further embodiment, the instrument for reducing the torque required to turn the upstream disk relative to the downstream disk includes the provision, on at least one of the abutting faces of the disks, of a relatively raised central region and a relatively recessed peripheral region whereby frictional contact between the abutting faces is localized essentially at the central regions thereof.

Inventors:

Fred W. Hendrick - Long Beach CA

Assignee:

Smith International, Inc. - Newport Beach CA

International Classification:

F16K 4700

US Classification:

251121

Abstract:

An orifice valve is disclosed comprising a valve body having a cylindrical upstream chamber, a downstream chamber having an oblong cross-sectional configuration adjoining and coaxial with the upstream chamber, and a shoulder comprising a pair of blind holes at the juncture of the upstream and downstream chambers. A downstream disk having a pair of fluid openings is mounted in the upstream chamber against the shoulder and comprises a pair of blind holes aligned with the blind holes in the shoulder. Rigid pins extend from the blind holes in the shoulder into the blind holes in the downstream disk to prevent rotation of the downstream disk. A rotatable upstream disk having a pair of fluid openings is mounted against the downstream disk and comprises a pair of blind holes. An operator member is provided comprising a forked turning member with a pair of tines, each having a blind hole in alignment with a blind hole in the upstream disk. Rigid pins extend from the blind hole in the upstream disk into the blind hole in the disk engaging member.

International Classification:

F16K 4704

US Classification:

13762531

Abstract:

To improve the turn-down ratio and reduce the erosiveness of the discharge flow in a multiple orifice valve having a movable upstream disk and an abutting stationary downstream disk, particularly when the disks are subjected to high fluid pressures, the disks are provided with cooperating fluid conducting openings having a modified circular sector shape. In the preferred embodiment, the modified circular sector shape of the fluid conducting openings includes a primary opening portion formed in the general shape of a circular sector and a secondary opening portion comprising a pair of substantially semicircular supplemental openings, one of the pair of openings being provided at a radially outermost location along a first one of two radially directed walls defining therebetween the central angle of the circular sector shaped primary opening portion, the other of the pair of supplemental openings being provided at a similar location along the second one of the two radially directed walls. The semicircular supplemental openings, when properly aligned to an optimum turn-down position, provide a significantly increased turn-down ratio and low-erosion discharge flow thorugh the downstream disk which is essentially always parallel with a central plane bisecting the fluid conducting openings of the downstream disk and passing through a common central axis of the disks.

International Classification:

F16K 4704

US Classification:

1376253

Abstract:

A multiple orifice flow control valve has a set of similar disks mounted in the body of the valve. A downstream disk is mounted in a fixed position in the valve body and an upstream disk is rotatable in the valve body in concentric face-to-face engagement with the downstream disk. There are two holes in the downstream disk and two holes in the upstream disk for control of the flow of fluids through the valve. The two holes in each disk are at non-adjacent apexes of a regular pentagon. By rotating the upstream disk 72. degree. in one direction the valve changes from closed to one-half open. By rotating the upstream disk through the same angle in the opposite direction, the valve changes from closed to fully open.

International Classification:

F16K 300

US Classification:

13762531

Abstract:

A disk valve construction having a unitary valve body formed with an internal cavity to receive therein a rotor spool passed through the fluid inlet end of the valve body. A replaceable sleeve member at an outlet chamber of the valve includes a truncated conical portion followed by a cylindrical portion of the fluid discharge end of the sleeve. The sleeve member is maintained in position by way of pressure of the fluid.

International Classification:

F16K 3153
F16K 2500

US Classification:

2512495

Abstract:

A disk valve construction having a unitary valve body. The valve is opened and closed by rotation of a drive shaft which is maintained in geared connection with a rotator spool positioned in an internal cavity of the valve body. The drive shaft extends in a direction substantially perpendicular to the longitudinal axis of the valve body. The drive shaft may be supported in a housing assembly to allow pressurization thereof for valve operation with steam and hazardous materials.
