Description

CLAMP ASSEMBLY
The present invention relates to a clamp assembly for connecting two pipe ends together and in particular but not exclusively to a safety clamp assembly for food and beverage processing applications.
It is known to connect two pipe ends or ferrules together using a conventional fitting called a tri-clamp which typically includes two clamp portions which are coupled together at one end by a hinge and at the other end by a wing nut and pivot bolt arrangement which is tightened to apply a clamping force to the ferrules and draw the same together. A gasket is typically provided between the ferrules to seal the connection when the ferrules are clamped together. These conventional fittings are commonly used in food and beverage processing applications because they provide a continuous inner wall surface to minimise any stepped transitions or crevices across the pipe connection where bacteria could grow.
However, conventional tri-clamps are not configured to allow a gradual release of pressure when opening the clamp and there is no adjustment to the opening mechanism. This can result in liquid spraying towards the operator from a loosened connection which can be particularly undesirable, especially if the fluid being transported through the pipe is at a relatively high pressure and/or at a relatively high temperature and/or is hazardous, such as acidic or combustible. Furthermore, the clamp itself can be violently ejected from the connection as a projectile which can cause injury to the operator or even worse. In addition, when a conventional tri-clamp is fully opened, it is completely detachable from the pipe ferrules and therefore requires separate handling and storage which could result in the clamp being mislaid or damaged.
It is an aim of certain embodiments of the present invention to provide a clamp assembly for connecting two pipe ferrules together which is safely adjustable and which allows a relatively slow release of pressure from the pipe connection without the risk of spraying or complete ejection from the connection.
It is an aim of certain embodiments of the present invention to provide a clamp assembly for connecting two pipe ferrules together which remains on the pipe when the clamp is in a fully opened state.
According to a first aspect of the present invention there is provided a clamp assembly for connecting two pipe ferrules together, comprising: a first clamp portion comprising an axially oriented elongate region having an axial through bore for mounting the first clamp portion on a first pipe including the first pipe ferrule, and a flange region extending outwardly from the elongate region and defining a first inner engagement surface for engagement with a respective surface of the first pipe ferrule; a second clamp portion comprising an axially oriented wall region and a cap region having an axial through hole for mounting the second clamp portion on a second pipe including the second pipe ferrule and defining a second inner engagement surface for engagement with a respective surface of the second pipe ferrule; wherein an outer surface of the flange region of the first clamp portion comprises a first screw thread for engagement with a second screw thread disposed on an inner surface of the wall region of the second clamp portion.
Optionally, the first inner engagement surface of the first clamp portion and the second inner engagement surface of the second clamp portion are tapered for engagement with correspondingly tapered surfaces of the first and second pipe ferrules.
Optionally, the flange region of the first clamp portion comprises an axially oriented lip region defining the outer surface including the first screw thread and an inner surface configured to be spaced from the first pipe ferrule for accommodating a lip region of a seal gasket locatable between the first and second pipe ferrules in use.
Optionally, the second screw thread extends substantially along the inner surface of the wall region.
Optionally, an outer surface of the cap region of the second clamp portion tapers outwardly in a direction away from the wall region.
Optionally, an end face of the first and second pipe ferrules comprises an annular recess for locating a correspondingly shaped annular bead of a seal gasket locatable between the first and second pipe ferrules in use.
Optionally, a diameter of the through bore of the first clamp portion is greater than an outer diameter of the first pipe to define an annular channel therebetween.
Optionally, a diameter of the through hole of the second clamp portion is greater than an outer diameter of the second pipe to define an annular channel therebetween.
Optionally, the elongate region of the first clamp portion and the wall region of the second clamp portion each comprise a pair of opposed and parallel flat surfaces for a tool to grip and rotate the clamp portion/s with respect to each other to tighten or loosen the clamp assembly.
Optionally, the clamp assembly comprises a seal gasket locatable between the first and second pipe ferrules in use.
Optionally, the seal gasket comprises a circumferential lip region for locating between an outer edge region of the first pipe ferrule and the first clamp portion.
Optionally, the lip region extends substantially axially away from the second clamp portion.
According to a second aspect of the present invention there is provided a method of connecting two pipe ferrules together, comprising: locating a first clamp portion on a first pipe including a first pipe ferrule, wherein the first clamp portion comprises an axially oriented elongate region having an axial through bore for mounting the first clamp portion on the first pipe; locating a second clamp portion on a second pipe including a second pipe ferrule, wherein the second clamp portion comprises an axially oriented wall region and a cap region having an axial through hole for mounting the second clamp portion on the second pipe; engaging a first inner engagement surface of the first clamp portion with a respective surface of the first pipe ferrule, wherein a flange region extending outwardly from the elongate region defines the first inner engagement surface; engaging a second inner engagement surface of the second clamp portion with a respective surface of the second pipe ferrule, wherein the cap region defines the second inner engagement surface; rotating the second clamp portion with respect to the first clamp, or vice versa, in a first direction to engage a first screw thread disposed on an outer surface of the flange region with a second screw thread disposed on an inner surface of the wall region and draw the first and second clamp portions, and in turn the first and second pipe ferrules, axially towards each other.
Optionally, the method comprises locating a gasket seal having a through hole between the first and second pipe ferrules to provide a continuous bore through the assembly.
Optionally, the method comprises providing an annular channel between the elongate region of the first clamp portion and the first pipe to allow fluid to axially escape when the assembly is loosened in use by rotating the second clamp portion with respect to the first clamp, or vice versa, in a second direction opposed to the first direction.
Description of the Drawings
Certain embodiments of the present invention will now be described with reference to the accompanying drawings in which: Figure 1 illustrates a first isometric view of a clamp assembly according to certain embodiments of the present invention; Figure 2 illustrates a second isometric view of the clamp assembly of Figure 1; and Figure 3 illustrates a cross sectional side view of the clamp assembly of Figures 1 and 2.
Detailed Description
As illustrated in the Figures, a first pipe ferrule 101 of a first pipe 300 is axially connected and sealed to a second pipe ferrule 103 of a second pipe 400 by a clamp assembly 100 according to certain embodiments of the present invention. The clamp assembly 100 includes a first clamp portion 102 coupled to a second clamp portion 104, wherein the first clamp portion 102 engages a first pipe ferrule 101 and the second clamp portion 104 engages the second pipe ferrule 103 to draw the ferrules together and compress a gasket located therebetween to seal the connection.
As illustrated in Figure 3, the first clamp portion 102 includes an elongate region 106 having an axial bore 108 for mounting the first clamp portion on a first pipe including the first pipe ferrule 101. A diameter of the bore 108 is greater than an outer diameter of the first pipe 300 to define a gap and channel therebetween. A circumferential flange region 110 extends outwardly from a proximal end of the elongate region 106 and terminates at a lip region 112 which is axially oriented to be substantially parallel with the elongate region 106. The flange region 110 defines a tapered inner surface 114 for engagement with a correspondingly tapered surface 116 of the first pipe ferrule 101 when the first clamp portion is urged against the first pipe ferrule in use. The lip region 112 defines an axially oriented inner surface 118 which is laterally spaced from an outer edge surface of the first pipe ferrule to thereby provide a gap for accommodating an annular lip region 202 of a gasket 200. An outer surface 120 of the flange region 110 comprises a screw thread.
The second clamp portion 104 includes an axially oriented wall region 122 and a cap region 124 having an axial through hole 126 for mounting the second clamp portion on a second pipe 400 including the second pipe ferrule 103. A diameter of the through hole 126 is greater than an outer diameter of the second pipe to define an annular channel therebetween. The cap region 124 defines a tapered inner surface 128 for engagement with a correspondingly tapered surface 130 of the second pipe ferrule 103 when the second clamp portion is urged against the second pipe ferrule in use. The outer surface 131 of the cap region 124 is also angled and is parallel with the inner surface 128 to better withstand a pressure increase inside the cap region when the connection is being loosened in use. Alternatively, the outer surface of the cap region may be substantially perpendicularly with respect to a longitudinal axis of the second clamp portion. Optionally, the second clamp portion 104 may include an elongate region extending axially from the cap region and having a bore therethrough like the elongate region of the first clamp portion. An inner surface 132 of the wall region 122 comprises a screw thread corresponding with the screw thread of the first clamp portion 102 such that the male first clamp portion threadably engages with the female second clamp portion when one or both the clamp portions are rotated with respect to each other to axially draw the tapered inner surfaces 114,128 thereof towards each other and in turn urge the pipe ferrules axially together and clamp the seal gasket 200 therebetween. Aptly, the screw thread extends entirely along the inner surface to allow the assembly to accommodate different thicknesses of pipe ferrule and with or without a seal gasket therebetween.
As illustrated in Figure 3, the seal gasket 200 includes an annular bead 204 on each side thereof for locating in a correspondingly shaped annular groove disposed in the end face of the respective pipe ferrule 101,103. These beads help to locate the seal gasket 200 when assembling the connection and the clamp assembly and provide additional sealing surface area to improve the effectiveness of the seal. The lip region 112 also helps to locate and hold the seal gasket 200 in situ on the first pipe ferrule 101 before the second pipe ferrule 103 is axially offered up to the seal gasket and the first and second clamp portions 102,104 are threadably coupled together.
Aptly, the seal gasket 200 comprises rubber or the like. The aperture in the seal gasket corresponds to the inner diameter of the pipe ferrules to thereby provide a continuous through bore without any stepped transitions, crevices, etc. where bacteria could otherwise grow.
As illustrated in Figure 1, the elongate region 106 of the first clamp portion 102 includes at least one pair of opposed and parallel flat surfaces 134,136 for a suitable tool, such as a spanner or wrench, to engage and hold or rotate the first clamp portion. The wall region 122 of the second clamp portion 104 comprises six flat surfaces 138 therearound, i.e. it is substantially hexagonal, for a suitable tool, such as a spanner or wrench, to engage and hold or rotate the second clamp portion. Alternatively, the second clamp portion may have a single pair of opposed and parallel flat surfaces for the tool to engage with, instead of three pairs of opposed and parallel flat surfaces. Aptly, in use, an operator may hold the first clamp portion with a suitable tool, such as a spanner or wrench, and rotate the second clamp portion with a suitable, such as a spanner or wrench.
Desirably, the second clamp portion 104 can be slowly loosened with respect to the first clamp portion 102 to gradually break the seal between seal gasket 200 and the pipe ferrules 101,103 and allow pressure within to be gradually and safely released. Any fluid passing the seal gasket 200 enters the space 300 within the second clamp portion 104 at a reduced pressure before being controllably channelled between one or both clamp portions 102,104 and the respective pipe and exiting in an axial direction along the pipe without spraying radially out of the connection and potentially injuring the operator. Furthermore, the two clamp portions 102,104 remain coupled together whilst the connection is loosened and the pressure is released which in turn prevents a part of the clamp assembly undesirably being projected towards the operator in the event of a high-pressure release. In such an event, the operator can quickly tighten up the clamp portions without risk of injury or damage to the pipework or clamp assembly itself. In addition, when the connection has been fully loosened and the pipes have been moved apart, the first and second clamp portions 102,104 remain on their respective pipes which prevents them from becoming lost or damaged and they can be quickly and easily coupled together to reconnect and seal the pipe ferrules after the seal gasket 200, for example, has been replaced or inspected.
The clamp portions of the illustrated embodiment include tapered inner surfaces 114,128 for engagement with correspondingly tapered surfaces 116,130 of the respective pipe ferrule but alternatively they may each include a substantially perpendicular surface with respect to a longitudinal axis of the clamp portion for engagement with a correspondingly perpendicular flange surface of the respective pipe ferrule. Further alternatively, the seal gasket 200 may not include the lip region 112. Aptly, the first and second clamp portions 102,104 are made of stainless steel suitable for hygienic processing applications.
Certain embodiments of the present invention therefore provide a clamp assembly for connecting two pipe ferrules together which is safely adjustable and which allows a relatively slow release of pressure from the pipe connection without the risk of spraying or complete ejection from the connection itself. The clamp assembly is also configured to remain on the pipes when the assembly is in a fully opened state which prevents loss or damage of the clamp portions.
