mechanical outlet

Abstract

Mechanical outlets form a tee joint by using a strap to clamp a pipe element to a saddle having a conduit. The saddle is attached to one end of the strap via an adjustable fastener. When the fastener is tightened to exert a tensile load on the strap, an angularly oriented action surface on the saddle and a reaction surface on the strap engage one another with the strap generally conforming to and pressing the pipe element against the saddle. Opposite ends of the strap and saddle engage one another via a yoke and enlarged head, allowing these ends to disengage to permit insertion of the pipe element between the strap and saddle.

[0002] This application is based on and claims priority to U.S. Provisional Application No. 63 / 180,115, filed April 27, 2021, which is hereby incorporated by reference. Technical Field

[0003] This invention relates to mechanical outlets for connecting pipe elements and other components. Background Technology

[0004] The saddle-shaped mechanical outlet for forming a tee is effective, but it suffers from drawbacks because installation typically requires a technician to handle four or more separate parts. Consequently, installation can be time-consuming and potentially difficult when the joint to be formed is located in areas with other pipes, fittings, and equipment, or when inconveniently positioned near walls, floors, or ceilings that restrict access. Clearly, there are opportunities to improve the mechanical outlet to form tee joints more quickly. Summary of the Invention

[0005] This invention relates to a mechanical outlet for forming a tee fitting in a tubular element. In an exemplary embodiment, the mechanical outlet includes a saddle partially surrounding a central space for receiving the tubular element. A tube extends through the saddle and has an inner portion extending into the central space. The inner portion is capable of engaging an opening in the tubular element. A belt partially surrounds the central space. A first end of the belt is attached to a first end of the saddle via an adjustable fastener. A second end of the belt and a second end of the saddle include hook assemblies for attaching the belt to the saddle. The belt is pivotable at the first end between a first position and a second position, in which the second end of the belt is not attached to the second end of the saddle, and in the second position, the second end of the belt is attached to the second end of the saddle.

[0006] By way of example, the conduit may also include an external portion projecting from the saddle. An action surface may be positioned near a first end of the saddle, and a reaction surface may be positioned near a first end of the belt, facing the action surface. In an example embodiment, the action and reaction surfaces are oriented at an angle relative to the longitudinal axis of the adjustable fastener, such that when the adjustable fastener is adjusted to pull the belt toward the first end of the saddle, the belt is pulled toward the first end of the saddle, thereby engaging the action and reaction surfaces.

[0007] In an example embodiment, the acting surfaces include an inner acting surface positioned between the central space and the adjustable fastener, and an outer acting surface. The adjustable fastener is positioned between the inner and outer acting surfaces.

The adjustable fastener is positioned between the inner and outer reaction surfaces.

[0008] In an example embodiment, the hook assembly includes a yoke positioned at a second end of either the saddle or the belt, and an enlarged head positioned at the second end of either the saddle or the belt. The head engages the yoke to attach the second end of the belt to the second end of the saddle. In a specific example, the yoke is positioned on the second end of the saddle, and the enlarged head is positioned on the second end of the belt.

[0009] Example embodiments may also include a saddle lug positioned on a first end of the saddle. The saddle lug defines an opening for receiving an adjustable fastener. A belt lug is positioned on a first end of the belt. The belt lug defines an opening for receiving an adjustable fastener. At least one of the saddle lug or the belt lug defines a clearance space adjacent to the adjustable fastener. By way of example, the adjustable fastener may include bolts and nuts. In another example, the exterior of the pipe includes a circumferential groove extending therearound. A seal may surround an interior portion of the pipe. The exterior portion of the pipe may be threaded.

[0010] An example mechanical outlet according to the invention may further include a release area positioned near a first end of the belt and facing a central space. In a specific example, the release area includes a portion of the belt, wherein the curvature of the belt surface is modified to provide a gap and thus better accommodate the tubular element.

[0011] The invention also covers a factory-pre-assembled mechanical outlet for forming a tee fitting in a tubular element. In an example embodiment, the factory-pre-assembled mechanical outlet includes a saddle partially surrounding a central space for receiving a tubular element. A tube extends through the saddle and has an internal portion extending into the central space and capable of engaging an opening in the tubular element. A belt partially surrounds the central space. A first end of the belt is attached to a first end of the saddle via an adjustable fastener. A second end of the belt and a second end of the saddle include hook assemblies for attaching the belt to the saddle. The factory-pre-assembled mechanical outlet is provided in either a first factory-pre-assembled state or a second factory-pre-assembled state. In the first factory-pre-assembled state, the belt is pivoted at the first end to a first position, wherein the second end of the belt is not attached to the second end of the saddle. In the second factory-pre-assembled state, the belt is pivoted to a second position, wherein the second end of the belt is attached to the second end of the saddle.

[0012] By way of example, the conduit also includes an external portion projecting from the saddle. Also by way of example, the factory pre-assembled machinery outlet according to the invention includes an action surface positioned near a first end of the saddle. A reaction surface is positioned near the first end of the belt, facing the action surface. The action and reaction surfaces are oriented at an angle relative to the longitudinal axis of the adjustable fastener, such that when the adjustable fastener is adjusted to pull the belt toward the first end of the saddle, the belt is pulled toward the first end of the saddle, thereby engaging the action and reaction surfaces.

[0013] In an example embodiment, the acting surface includes an inner acting surface positioned between the central space and the adjustable fastener, and an outer acting surface. The adjustable fastener is positioned between the inner and outer acting surfaces. The acting surface also includes reaction surfaces, including an inner reaction surface positioned between the central space and the adjustable fastener, and an outer reaction surface. The adjustable fastener is positioned between the inner and outer reaction surfaces.

[0014] In an exemplary embodiment of the invention, the hook assembly includes a yoke positioned at a second end of either the saddle or the belt.

[0034] This invention relates to a mechanical outlet for forming a tee fitting in a pipe element. Figure 1 and Figure 2 An example mechanical outlet 10 according to the invention is shown. The mechanical outlet 10 includes a saddle 12 that partially surrounds a central space 14 for receiving a tubular element (not shown). The saddle 12 is provided in different sizes with different radii of curvature to accommodate different tube diameters. A tube 16 extends through the saddle 12. Figure 3 As shown, the conduit 16 has an inner portion 18 extending into a central space 14. The size of the inner portion 18 is adapted to accommodate openings in the sidewalls of the connecting pipe element. A seal 20 surrounds the inner portion 18 of the conduit 16 and provides a seal between the saddle 12 and the pipe element when compressed between the saddle 12 and the pipe element. Referring to some example seal structures, the example seal 20 is formed of an elastomer such as a rubber compound and may include a simple gasket or a pressure-activated seal. In factory-pre-assembled machine outlets (described below), it is advantageous if the seal 20 is held to the saddle 12 so as not to become a loose part during the assembly of the joint. The seal 20 may be held within a recess 19 via a frictional fit against the inner portion 18 or against the saddle. Figure 1-3 As further shown, the conduit 16 may also include an external portion 22 projecting from the saddle 12 away from the central space 14. The external portion 22 is capable of engaging with another component (as cited as examples, such as a valve, a spray nozzle, or another pipe element). In this example embodiment, the external portion 22 of the conduit 16 is provided with a circumferential groove 24 to permit attachment via a mechanical coupling. Figure 6A and Figure 6B As shown, the outer portion 22 may also be threaded, with internal or external threads for compatibility with specific components, as appropriate.

[0035] The mechanical outlet 10 also includes a belt 26. The belt 26 may be formed of the same material as the saddle 12 (e.g., ductile iron) and also partially surrounds the central space 14. Figure 3 As shown, the first end 28 of the strap 26 is attached to the first end 30 of the saddle 12. In this example, attachment is achieved via an adjustable fastener 32 (hereinafter referred to as "fastener 32") comprising a nut 34 and a bolt 36. Figure 1 and Figure 2 and Figure 4 and Figure 5 As shown in the comparison, the second end 38 of the belt 26 can be attached to the second end 40 of the saddle 12 via the hook assembly 13 (described below). Figure 1 and Figure 2The mechanical outlet 10 is shown in a configuration in which the second end 38 of the band 26 is not attached to the second end 40 of the saddle 12. As explained below, this first position of the band 26 represents a first factory pre-assembled state of the mechanical outlet 10. Figure 4 and Figure 5 The diagram shows a belt 26 in a second position, including a pre-assembled state in a second factory, wherein a second end 38 of the belt is attached to a second end 40 of a saddle 12. The belt 26 is pivotable between a first end 28 and a second position.

[0036] In this example embodiment, a pivotable attachment between the saddle 12 and the belt 26 is achieved using a saddle lug 42 positioned on the first end 30 of the saddle 12 and a belt lug 44 positioned on the first end 28 of the belt 26. Both the saddle lug 42 and the belt lug 44 define corresponding openings 46 and 48 for receiving the fastener 32 (see [link to documentation]). Figure 3 ).like Figure 1 As shown in the first pre-assembled state of the factory, the adjusting fastener 32 holds the belt 26 to the saddle 12 while allowing a gap 50 between lugs 42 and 44, which permits the belt and saddle to pivot relative to each other. This pivoting capability allows the mechanical outlet 10 to be opened during assembly to receive tubular components in the central space 14. When pivoting movement occurs about the fastener 32, it is advantageous that the shape and size of at least one or both of the corresponding opening 46 of the saddle lug 42 and the corresponding opening 48 of the belt lug 44 are adapted to define a gap space in the lugs or lugs around the fastener 32 in order to permit pivoting movement between the saddle 12 and the belt 26.

[0037] Figure 3 , 3A Figures 3B and 3C illustrate the clamping feature of the mechanical outlet 10. The clamping feature is achieved through the engagement between the respective mating portions of the acting surface 60 and the reaction surface 62. Figure 3A The acting surface 60 is positioned on the saddle 12 near its first end 30, and the reaction surface 62 is positioned on the belt 26 near its first end 28. In this example, the acting surface and the reaction surface are located on the saddle lug 42 and the belt lug 44, respectively. The acting surface 60 and the reaction surface 62 face each other. Figure 3A and 3BAs shown, the action surface 60 on the saddle 12 can be divided into an "inner" action surface 60a and an "outer" action surface 60b. The inner action surface 60a is located between the central space 14 and the fastener 32, and the fastener 32 is located between the outer action surface 60b and the inner action surface 60a. Similarly, the reaction surface 62 can be divided into an "inner" reaction surface 62a and an "outer" reaction surface 62b. The inner reaction surface 62a is located between the central space 14 and the fastener 32; the fastener 32 is located between the outer reaction surface 62b and the inner reaction surface 62a.

[0038] Export 10 is designed to accommodate a certain range of pipe component outer diameter tolerances, such as... Figure 3A and 3B As shown in the image. Figure 3A An inner working surface 60a is shown engaging an inner reaction surface 62a, with a gap between the outer working surface 60b and the outer reaction surface 62b (wherein the inner working surface 60a and the inner reaction surface 62a act as the engagement portion of the working surface 60 and the reaction surface 62). This occurs when a tubular element having an outer diameter at the lower end within the outer diameter tolerance range is received into the central space 14 before the fastener 32 is tightened. Figure 3B An outer working surface 60b is shown engaging an outer reaction surface 62b, with a gap existing between the inner working surface 60a and the inner reaction surface 62a (wherein the inner working surface 60b and the inner reaction surface 62b act as the engagement portion of the working surface 60 and the reaction surface 62). This occurs when a tubular element having an outer diameter at the upper end of the outer diameter tolerance range is received into the central space 14 before the fastener 32 is tightened.

[0039] The acting surface 60 and the reaction surface 62 are initially oriented at an angle relative to the longitudinal axis 64 of the fastener 32 and to a plane 65 perpendicular to the longitudinal axis 64 of the fastener 32, such that when the fasteners are adjusted (tightened) to pull them into engagement, the clamping force applied by the fastener 32 works through the angled interface between the acting surface 60 and the reaction surface 62, causing the belt 26 to be pulled toward the first end 30 of the saddle 12. Thus, as Figure 3 As shown, tension is created in the belt 26 when the second end 38 of the belt 26 is attached to the second end 40 of the saddle 12. Figure 3CAs shown, the tension applied to the belt 26 will cause the mating portions of the acting surface 60 and the reaction surface 62 to engage face-to-face, and will press the pipe element 15, received within the central space 14, against the saddle 12, thereby also pressing the seal 20 to achieve a tight fluid connection between the mechanical outlet and the pipe element. For practical design, the orientation angle 66 between the acting surface 60 and the reaction surface 62 and the longitudinal axis 64 of the fastener 32 can be in the range of 30° to 60°, of which an orientation angle of approximately 55° is advantageous. When undeformed ( Figure 3 It is further advantageous if the radius of curvature of the band 26 is greater than the radius of the outer surface of the tube element it engages with. This dimensional relationship allows for easier insertion of the tube element into the central space 14, and perhaps the band 26 can roughly conform to the tube element to enhance the tightening effect. Figure 3C When undeformed ( Figure 3 The saddle 12 advantageously has a radius of curvature that substantially matches the outer surface of the tube element within tolerance.

[0040] like Figure 3B As further shown, the outer acting surface 60b and the outer reaction surface 62b can be used as stop surfaces to limit the pivoting movement between the saddle 12 and the belt 26. The facing relationship and proximity of the acting surface 60b and the reaction surface 62b (controlled by the fastener 32) allow the outer reaction surface 62b to contact the outer acting surface 60b when the second end 38 of the belt 26 is not attached to the second end 40 of the saddle 12, thereby limiting the axis 58 (see [reference needed]) passing between the belt and the saddle around the lugs 42 and 44. Figure 1 The degree of pivoting motion of the axis 58 is approximately parallel to the longitudinal axis of the tubular element (not shown) received within the central space 14.

[0041] like Figure 2 and Figure 3 As shown, the second end 38 of the belt 26 and the second end 40 of the saddle 12 can be releasably attached to each other using the hook assembly 13. In this example embodiment, the hook assembly 13 includes a yoke 68 that receives an enlarged head 70. In this example embodiment, the yoke 68 is positioned at the second end 40 of the saddle 12, and the enlarged head 70 is positioned at the second end 38 of the belt 26, although the positions can be interchanged. To provide a positive mechanical engagement between the yoke 68 and the enlarged head 70, the enlarged head can be shaped into a cylindrical shape to be received within a concave surface 72 formed in the yoke 68.

[0042] Using mechanical outlet 10 to form a tee joint begins at the mechanical outlet, which is as follows: Figure 1 and Figure 2 (Pre-assembly state at Factory 1) or Figure 4 and Figure 5One of the two pre-assembled factory states shown in the second pre-assembled factory state is received. Mechanical outlet 10 can be provided as shown, or components (such as valves or sprayers) attached to the external portion 22 of pipe 16 can be supplied. The first end 28 of belt 26 and the first end 30 of saddle 12 are loosely attached to each other by fasteners 32. The second end 38 of belt 26 and the second end 40 of saddle 12 may or may not be engaged. In either the first or second pre-assembled factory state, the pipe element (not shown) can be positioned within the central space 14 surrounded by the saddle and belt. When mechanical outlet 10 is in the second pre-assembled factory state (… Figure 4 and Figure 5 When the tube element is in its pre-assembled state in the first factory, it can be positioned within the central space 14 by inserting the free end of the tube element into the central space 14. Figure 1 and Figure 2 When the tube element is positioned, it is positioned within the central space 14 by passing the tube element through the middle of its ends between the corresponding detached end 38 of the belt 26 and the corresponding detached end 40 of the saddle 12. Figure 3C As shown, the inner portion 18 of the conduit 16 will then engage with the opening 17 in the pipe element 15, wherein the seal 20 is initially pressed between the pipe element and the saddle 12. Figure 1-3 As shown in 3C, if the belt 26 is pivoted about axis 58 at its first end in the first factory pre-assembled state, the second end 38 of the belt is moved toward the second end 40 of the saddle. Then, the second end 38 of the belt 26 is attached to the second end 40 of the saddle 12 by engaging the enlarged head 70 with the concave surface 72 of the yoke 68. Next, the fastener 32 is tightened to pull the first end 28 of the belt 26 and the first end 30 of the saddle 12 toward each other, thereby engaging the acting surface 60 with the reaction surface 62 (see [reference]). Figure 3B Further tightening of the fastener 32 causes the acting and reaction surfaces to slide across each other, thereby pulling the band 26 toward the first end 30 of the saddle 12. The tension on the band 26 causes it to deform and tighten the tubular element against the saddle, compressing the seal 20 to form a fluid-tight connection between the tubular element and the mechanical outlet 10. Components such as a second tubular element, valve, sprayer, etc. (not shown) can then be attached to the outer portion 22 of the pipe 16 (if not already present). For example, attachment can be achieved using a mechanical coupling to engage the groove 24, or the outer portion 22 can be threaded (internal or external) to accommodate a specific component of interest, if required. Figure 2 , 3As shown in 3D, it is advantageous to include a release region 25 on the belt 26, which is positioned near the first end 28 of the belt 26 and facing the central space 14. The release region 25 comprises a portion of the belt 26, wherein the curvature of the belt surface is modified to provide clearance and better accommodate the tubular element 15 during assembly at the mechanical outlet 10. The release region 25 is beneficial for assembly in both the first and second pre-assembled states and can be formed, for example, during the casting of the belt 26, or the belt can be machined to include the release region 25.

[0043] The mechanical outlets according to the invention are expected to offer numerous advantages, including more efficient assembly of connections, as there are no loose parts to handle and only one bolt needs to be tightened to secure the joint. The mating of pads provides a visual indication that the assembly is complete and eliminates the need to measure the torque applied to the fasteners. The mating of pads also avoids the failure mode of belt or saddle lug shearing due to excessive fastener torque.

Furthermore, the scope of this disclosure is intended to cover any and all modifications and combinations of all elements, features, and aspects described in the specification and claims and shown in the drawings.
