Description

Ferrule Type Conduit Seam {FERRULE TYPE CONDUIT FITTING}

The present invention relates generally to the attachment of a ferrule type female nut-stem attachment catheter for use with an enhanced flexible hose and adapter. In particular, the present invention is applicable to high-pressure pipe and hose applications and high-pressure adapters, and it will be convenient to disclose the present invention in the context of such exemplary applications. It should be understood, however, that the present invention is not limited to that application and can be used with many other similar fluid seal configurations.

The following description of the background of the present invention is intended to facilitate understanding of the present invention. It should be understood, however, that the description does not acknowledge or acknowledge that any material discussed has been disclosed, publicly disclosed, or was part of the general knowledge common to the priority date of the present application.

The high pressure pipe and hose operation and the high pressure adapter require seams or couplings that can be secured to the ends of the conduits (e.g., hoses or pipes) and provide a secure, fluid tight connection with the other seams. One such attachable conduit joint includes a ferrule-type connector for connection to the end of the conduit at one end and a female nut configured to receive a threaded male connector of the adapter at the other end.

The ferrule-type conduit joint typically has a male-stem portion insertable into the hose end and a ferrule-type sleeve concentric with the male-stem. In addition, the male and female and ferrule sleeves define an annular cavity for receiving the hose end. By pinching the hose end in the annular cavity between the ferrule sleeve and the stem, such as by radially reducing some of the parts or elements of the ferrule sleeve or radially increasing the size of the male-stem, Is held on the hose.

The female nut connector includes a rotatable sleeve having an inner thread configured to cooperate with an outer thread of a cooperating male connector. The female nut is rotatably mounted on a nut stem fluidly connected to the ferrule-type connector. The nut stem includes a sealing end that contacts the end of the adapter (which is received within the rotatable sleeve) and forms a fluid seal. The sealing end is typically planar with an end that is radially perpendicular to the longitudinal axis of the joint or may include a linear or planar inner tapered surface between the outer diameter of the nut stem and the inner diameter of the nut stem.

Figures 4 and 5 show details of the inner sealing end of the prior art ferrule-type connector and nut stem (Figure 5). As shown in Figure 5, a seal is created when the tapered end of the adapter received in the nut contacts the tapered sealing surface of the nut stem. In this configuration, the contact surface between the adapter and the tapered sealing surface of the sealing end of the nut stem is a small annular area. The fluid tight seal requires a tight, aligned fit between the threaded cooperating part of the female nut and the adapter, thereby ensuring such adequate surface contact. Nonetheless, fluid pressure, rough handling or handling, and / or damage to this area may alter this alignment and may alter the integrity of such seals.

Accordingly, it would be desirable to provide a ferrule-type conduit joint having an alternate or improved seal between the female nut and the male connector of the adapter within the female nut.

The present invention provides seams and associated systems and methods that include two fluid connection connectors including a female nut connector and a single integrated ferrule.

A first aspect of the present invention provides a fluid seal having two fluidically connected connecting ends comprising a ferrule-type connector configured to be fixed on an end of a conduit and a female nut connector, the female nut connector having a fluid- Wherein the connector section has a distal end comprising an internally tapered sealing section including an annular portion having a convex surface adapted to be in contact with the cooperating end of the male connector inserted in the nut connector .

The fluid seals of the present invention include a convex sealing surface configured to be in contact with the cooperating end of the male connector inserted into the nut connector. The cooperating end of the male connector typically includes a cooperating annular surface contacting a surface of the sealing section tapered into the interior of the tubular connector section to create a seal therebetween. The convex sealing surface provides a curved engagement surface that better accommodates changes, alignment problems, and / or movement between the contact surfaces. Indeed, the sealing surface provides a better fit and seal between the male connector and the contact surface of the connector stem. Thus, the fluid seals of the present invention can be used for higher fluid pressure applications compared to conventional fluid seals having connector sections with planar tapered sealing surfaces (as shown, for example, in FIGS. 4 and 5) .

It is to be understood that the internally tapered sealing section is intended to mean that the taper of the sealing section extends from the outer edge of the distal end to the seam, i. E. Towards the opposite end of the seam comprising the ferrule-type connector.

The fluid seal's female nut connector is configured to receive and seal a complementary threaded male connector. The cooperating seal is the result of the contact bond between the sealing section tapered into the tubular connector section of the fluid seal and the surface of the male connector, typically the tapered end surface. As described above, the convex shape of the sealing section tapered into the interior of the tubular connector section provides a sealing property favorable to the fluid seals of the present invention.

In some embodiments, the tapered sealing section includes an inner surface of the tubular connector section between the inner diameter and the outer diameter of the tubular connector section. Thus, the taper of the sealing section is inclined inwardly from the outer diameter to the inner diameter in the axial direction toward the ferrule-shaped connector.

Within the tapered sealing section, the convex surface may comprise, for example, a portion of the surface which is a central annular portion of the surface. That portion may be as small as 10 to 40% or may extend to a larger portion, for example 50% to 95% of the surface. In some embodiments, the convex surface extends substantially throughout the inwardly tapered sealing section. Thus, the surface of the tapered sealing section forms a convex shape.

The dimensions and curvature of the convex taper may be any suitable dimension. The convex taper may have any suitable curve or arc to provide a convex shape. Examples of suitable arcs include circular or curved segments or sectors, such as circles, ellipses, parabolic segments, arcs, and the like. In some embodiments, the convex taper includes a circle segment or sector having a radius between 0.5 and 2 times the inner radius of the tubular connector section. In some embodiments, the convex taper has a radius between 0.5 and 1.5 times the inner radius of the tubular connector section.

The nut connector preferably includes a standard nut connector. Thus, in some embodiments, the nut connector is a hexagonal nut. However, it should be understood that other types of nut connectors may be used, such as, for example, a circular nut. In some embodiments, the outer surface of the nut connector is colored. Any color such as red, orange, green, purple, blue, red, violet, white or the like is possible, but the outer surface of the nut connector is preferably colored black. In particular, the color used on the nuts in black provides a distinct contrast to the tubular connector section and the ferrule-type connector section of the fluid seam, which is typically metallic silver, with the original material color of the manufacture. Such a contrasting color combination allows the seam to be readily identifiable to the consumer and can provide an indication of the origin of the fluid seam, particularly the transaction origin, that is identifiable to the application.

The tubular connector section may have any suitable configuration. In some embodiments, the tubular connector section includes a stem having a nut mounted thereon. The nut may be mounted on the tubular connector section using a variety of mounting configurations. In some embodiments, the connector section includes an annular projection or flange to retain the nut connector thereon. In some embodiments, the connector section includes an annular groove or channel that receives an annular flange of the nut connector to retain the nut connector thereon.

It is to be understood that the male connector is preferably an integral part of the adapter, preferably an adapter, more preferably a high-pressure adapter. The adapter has a male connector that is receivable within the nut connector at one end and another connector arrangement (male, female, snap fit, etc.) on the other end. The adapter may have any suitable configuration selected for a particular application. Examples of suitable adapters include, but are not limited to, straight, compact and swept 45 ° and 90 °, sockets, bulkheads, caps, plugs, reduced bushes, tees, weld- .

The ferrule-type connector is configured to be fixed, for example, on the end of a conduit, such as a pipe or hose, preferably a reinforced flexible hose. The ferrule-type connector preferably includes a ferrule-shaped sleeve extending around the ferrule stem to cooperatively catch the end of the duct within the ferrule-shaped connector. The ferrule sleeve is configured to receive a conduit therein, and the ferrule stem (male-to-stem) is configured to be inserted within the conduit. In addition, the ferrule stem and the ferrule sleeve define an annular cavity for receiving the hose end.

By pinching the end of the conduit in the annular cavity between the ferrule sleeve and the stem, such as by radially reducing some parts or elements of the ferrule sleeve or by radially increasing the size of the ferrule stem, And is retained on the conduit. In some embodiments, the ferrule sleeve is configured to be defined around the end of the conduit. In some embodiments, the ferrule stem is configured to extend the diameter of the end of the conduit into which the stem is inserted. Of course, a combination of the sleeve limitation described above and the ferrule stem extension described above can also be used.

It should be understood that the ferrule-type connector may have any number of suitable configurations. Some ferrule-type connectors are reusable and use mechanical means of seam, such as a threaded member to activate the means for pinning the hose against the stem, as described, for example, in European Patent EP0241651. For example, a ferrule-type connector may include a ferrule, more specifically a ferrule-type ferrule of radius-size of the ferrule sleeve that is reduced through crushing by, for example, a crimping process or other means . In another embodiment, the ferrule-type connector includes a toothed stem with ferrule locking collar. In some embodiments, the ferrule sleeve may be pre-attached to the stem and then attached to the ferrule locking collar. In an exemplary embodiment, the ferrule sleeve is integrally connected to the ferrule stem. The ferrule may be configured to catch the conduit end without insertion or insertion.

The ferrule-type connector can be attached to the connector stem using a variety of different connections. In some embodiments, the ferrule-type connector is integrally connected, and preferably integrally formed, with the tubular connection section. The fluid seal preferably includes an internal bore extending between the ferrule-type connector and the distal end of the connector section. Advantageously, the internal bore is continuous when the ferrule-type connector and tubular connection section are integrally connected. Therefore, no fluid may leak when flowing through the inner bore.

Fluid seals typically include an intermediate portion between a ferrule-type connector and a nut connector for fluidly connecting such a connector end of a fluid seal. The intermediate portion may have any suitable configuration. In some embodiments, the middle portion is a linear or linear configuration. In another embodiment, the middle portion is angled, for example, at right angles, 45 degrees, 30 degrees, and the like. In yet another embodiment, the intermediate portion comprises at least one curved section.

The conduit joints of the present invention may be made from any suitable material, including, but not limited to, polymers, metals, alloys thereof, and the like. Examples include plastic, stainless steel, steel, iron, copper, brass, and the like.

Figure 5 is an enlarged view of the connection between the male-to-male adapter shown in Figure 4 and the nut connector of a conventional (prior art) ferrule-type fluid seal.

The complete seam / fluid seam 100 according to the present invention in connection with the adapter seam 105 is shown in Figs. The conventional (prior art) fluid seals 200 coupled with the same adapter seals 105 (shown in Figs. 1A-3) are shown in Figs. 4 and 5 for comparison.

1A, 1B and 2), the fluid seal 100 includes a ferrule-type connector 110, a nut connector 115, and a ferrule- And a connector stem 120 to which the nut connector 115 is rotatably mounted. The ferrule-type connector 110 is formed integrally with the connector stem 120 and the connector stem 120 forms the unilateral end of the fluid seal 100 and the ferrule 110 is connected to the other Forming an axial end to form a single piece of unit. 2, the fluid seal 100 has an internal bore 120 extending longitudinally through the center of the seam 100, and the ferrule-type connector 110 and the nut connector 115 To form a fluid passage.

The illustrated adapter seam 105 has two threaded male connector ends, including a high pressure adapter with a straight male-to-female thread configuration. It should be appreciated that such adapter joints 105 may have any suitable configuration selected for a particular application. Also, while one end includes a male threaded connector, in other embodiments, the other connector end may have any suitable connector configuration including female, quick fit, snap fit, and the like. Examples of adapter seals 105 that can be received by the nut connector 115 include straight, compact and swept 45 ° and 90 °, sockets, bulkheads, caps, plugs, reduction bushes, tees, weld- .

The nut connector 115 shown includes a hexagonal internal thread nut that is rotatably mounted on the tubular connector stem 120. The connector stem 120 includes a tubular stem that extends from the end of the ferrule-type connector 110. The connector stem 120 includes an annular channel 122 that receives an annular flange 124 of the nut connector 115 to retain the nut thereon. The annular channel 122 defines an annular projection / flange 126 located behind the annular flange 124 of the nut connector 115 and retains the nut connector 115 thereon.

1B, the outer surface of the nut connector 115 is colored black in some embodiments. The black provides a distinct contrast to the ferrule-type connector 110 and the stem connector 120 of the fluid seal 100, which typically has the original material color of, for example, making the metal seal. Such a contrasting color combination may provide the consumer with an indication of the origin of the seam, in particular the origin of the transaction, which allows the fluid seal 100 to be easily identifiable and identifiable to the application. It should be understood that the color may be applied using any suitable method, such as application of a coating. The coating may be a colored paint, powder coating, etc. designed to coat and adhere the material of the nut connector 115. In some embodiments, the color may be a result of a combination of the material of the nut connector 115 or the outer surface layer of the nut connector 115.

The nut connector 115 is configured to receive, for example, the adapter seam 105 and to seal and cooperate with a complementary threaded male connector. As best seen in FIG. 3, the connector stem 120 has a distal end 128 that includes an internally tapered sealing surface 130. This sealing surface 130 has a convex shape. The sealing surface 130 is tilted inward from the outer diameter in the axial direction toward the ferrule-type connector 110 to the inner diameter. The dimensions and curvature of the convex shape may be any suitable dimension. The convex taper may have any suitable curve or arc to provide a convex shape.

The cooperative seal between the male connector 105 and the nut connector 115 is the result of the contact bonding between the convex sealing surface 130 of the connector stem 120 and the tapered end surface 135 of the male connector 105 . The convex sealing surface 130 provides a better flexed engagement surface in the receiving variation, alignment problem or movement between the contacting surfaces. Thus, the convex shape of the sealing surface 130 of the connector stem 120 provides a sealing property favorable to the fluid seam 100 of the present invention.

This can be seen by comparison with the tapered sealing surface 230 of the plane of normal fluid seals shown in Figs. It should be appreciated that such a fluid seal 200 has a similar configuration to the fluid seal 100 shown in Figs. 1A-3, except for the configuration of the tapered sealing surface 230. The same features are provided with the same reference number plus 100.

5, the connector stem 215 of this conventional fluid seal 200 has a distal end 228 that includes a planar inner tapered sealing surface 230. The cooperation seal between the adapter seam 105 and the nut connector 215 thus results in a contact bond between the flat sealing surface 230 of the connector stem 215 and the tapered end surface 135 of the adapter seam 105 to be. The contact surface between the adapter seam 105 and the flat sealing surface 230 of the connector stem 215 is a small annular area. The fluid tight seal requires an airtight, aligned fit between the threaded cooperating parts of the adapter seam 105 and the nut connector 215 to ensure this proper surface contact. Fluid pressure and damage can change the fit in these small contact connection / sealing areas.

Referring again to Figures 1A-3, the illustrated ferrule-type connector 110 includes a ferrule-shaped sleeve 140 that extends around the ferrule- In addition, the ferrule stem 142 and the ferrule sleeve 140 define an annular cavity 144 for receiving the hose end. The ferrule sleeve 140 and the ferrule stem 142 cooperate to capture the end of the conduit (not shown) within the ferrule-type connector 110. The ferrule sleeve 140 is configured to receive a conduit therein. The ferrule-shaped stem 142 (male-stem) is configured to be inserted into the conduit.

Shaped sleeve 140 and the stem 142, such as by radially reducing some of the components or elements of the ferrule sleeve 140 or radially increasing the size of the ferrule- The ferrule-type connector 110 is retained on the conduit by pinching the conduit end in the cavity 144. [ This may be accomplished by defining, crimping, etc. the ferrule sleeve 142 around the end of the conduit or by expanding the diameter of the end of the conduit around the ferrule stem 142. It should be understood that the present design includes all such ferrule-type connector configurations. In the illustrated embodiment, the ferrule sleeve 140 and the stem 142 are integrally connected.

It should be understood that the fluid seals 100 shown include linear seams, but fluid seams may include intermediate angled or curved portions. For example, the middle portion may include a right angle, a 45 degree angle, a 30 degree angle, or one or more bent sections, and the like.

The fluid seal 100 is secured to the annular cavity 144 in the ferrule sleeve 140 of the ferrule-type connector 110 and to the conduit (not shown) by inserting an open conduit end onto the ferrule stem 142 do. The conduit is then secured inside thereof using suitable friction, crushing, for the ferrule-type connector design. The attached conduit is then ready to be attached to the fluid system by threading the nut connector 115 onto an adapter or other end that is, for example, the adapter seam 105 shown.

Those skilled in the art will appreciate that the present invention described herein may permit variations and modifications other than those specifically described herein. This invention is understood to include all such variations and modifications as fall within the spirit and scope of the present invention.
