Description

VALVE GUARD
The present invention relates to a valve guard. In parflcular, the present invention r&ates to a valve guard for a gas cyUnder valve.
Cyhnder valve assembUes for gas cyflnders and the Uke are weh known. TraditionaUy, cylinder valves are provided with a hand wheel which is operable by rotation to open and close the valve. More recently, cyhnder valves which use levers to operate the valve mechanism have become known. Such a cylinder valve assembly is disclosed in US 5,975,121.
In order to prevent damage to valve assemblies during transit and/or use, it is common to provide a valve guard. Typically valve guards enclose the valve assembly to a certain extent to afford the necessary protection to the valve. However, this can be problematic as the guard can reduce access to the valve operating mechanism and outlet.
An example prior art guard is disclosed in US 5975,121 mentioned above. In this example the guard substantially surrounds the valve assembly and slots are provided in the guard to allow actuation of the lever and access to the valve outlet. This enclosed valve guard arrangement significantly reduces access to the valve assembly and outlet. In particular, the enclosed guard hides the position of the actuating lever from certain lines of sight making it more difficult for an end user to ascertain whether the valve is open or closed from a large range of angles around the cylinder.
The present invention provides a valve guard for a gas cylinder comprising a cylinder and valve assembly, the valve guard comprising a base portion and at least one cantilevered arm extending away from the base portion, wherein, in use, the at least one cantilevered arm is arranged to extend between the base portion and a position substantiaUy in line with a centreline of the cylinder.
The cantilevered arm provides protection to the valve assembly in the event that the cylinder is dropped or knocked over, whilst maintaining good access to the valve assembly and outlet. In addition, visibility of the valve actuatIon mechanism is substantially maintained allowing the user to ascertain the position of the actuation mechanIsm from a large number of angles around the cylinder. This is particularly advantageous for lever operated valve assemblies.
The cantilevered arm preferably comprises a bulbous portion located at the distal end of the cantilevered arm to help reduce impact damage to any other item that the guard may hit as it drops or falls over. The bulbous portion preferably comprises a churning knob to aid manual manipulation of the gas cylinder.
Preferably the base portion is of substantially concave torn to provide side protection to the valve assembly.
A sidewall portion of the base portion preferably comprises an opwihig allowing access to the valve assembly and reducing weight of the valve guard. The opening preferably defines a handle to aid manual handling of the gas cylinder.
In a preferred embodiment, a sidewall portion of the base portion comprises a raised portion to protect particularly delicate parts of the valve assembly. The raised portion is preferably arranged to be located proximate an operating mechanism of the valve.
Preferably, the at least one cantilevered arm Is generally of tapered form, tapering from the base portion towards Its distal end. This provides strength and stiffness at the base of the cantllevered arm which Is most likely to tail during an impact.
The valve guard preferably comprises an agnrnent feature arranged to aUgn with a selected aHgnment feature on the cyUnder or valve to aid correct positioning of the guard on the gas cyflnder in r&ation to the valve assembly.
In a preferred embodiment, the valve guard comprises at east two secflons arranged, in use, to connect together in position around a valve assembly. This aids assembly of the guard around the valve assembly.
In another aspect, the present invention provides a kit of parts comprising a plurality of sections for forming a valve guard.
In a further aspect, the present invention provides a gas cylinder assembly comprising a gas cylinder, a vale assembly and a valve guard as described above.
Examples of the invention will now be described with reference to the following drawings in which: Figure 1 shows a schematic isometric view of a cylinder valve and valve guard assembly with the valve operating lever shown in the oW position; Figure 2 shows a schematic isometric view of the cylinder valve and valve guard assembly of Figure 1 wllh the lever shown in the "open" position; Figure 3 shows an isometric view of an alternative cylinder valve and valve guard assembly with the valve operating lever shown in the "off" position; Figure 4 shows an isometric view of the valve guard of Figure 3 in isolation; and Figure 5 shows an alternative isometric view of the valve guard of so Figure 4.
Referring to Figure 1, a cyHnder and valve assembly 1 is shown comprising a gas cylinder 2, a valve assembly 10 and a valve guard 20. The valve assembly 10 is connected to the cylinder 2 by a threaded connection (not shown) as is well known in the art, and the guard 20 is connected to the neck ring of the cylinder by a threaded connection, also weU known in the art The valve assembly 10 comprises an actuation ever 12 and an outlet 14. In the position shown in Figure 1 the ever 12 is in the downward or off' position such that gas is prevented from flowing from the outlet 14.
The valve guard 20 comprises a base portion 21 and a cantilevered arm 22 which extends from the base portion 21 to a distal end 23. The distal end 23 of the arm 22 has a bulbous form and the proximal end 24 of the arm has a thicker crosssection that the crosssection of the arm 22 immediately proximate the bulbous end 23. This configuration provides stiffness to the arm 22 in the region most likely to fail during an impact. The bulbous end 23 serves to reduce impact damage on any object struck by the end 23. The guard material may typicaHy comprise, for example, cast metals, plastics or reinforced plastics.
The distal end of the cantilevered arm 22 extends to a position substantially above the centreline of the gas cylinder 2. The arm 22 therefore bends forward over the valve assembly 10. This configuration protects the valve assembly 10 from damage in the event that the cylinder valve assembly us dropped of knocked over. The guard 20 is configured so that if the cylinder valve assembly 1 falls forwards or sideways, in the absence of projecting objects, the first point of contact will not be valve assembly 10 but either the base portion 21 or the arm 22 of the guard 20.
It is possible that the lever 12 may be damaged or broken off if the so cylinder valve assembly 1 faUs over. However, the guard 20 will protect the valve from impacts which may damage the valve and lead to loss of the valve from the cylinder 2.
Figure 2 shows the lever 12 of the valve assembly in the raised or openhs position. As can be seen in both figures 1 and 2, the valve guard aflows almost 360° access to the ever 12 and outlet 14. Thus the end user is able to access both the ever 12 and outlet 14 from a large number of angles and is not unduly restricted by the guard 20.. In addition, as best shown in Figure 2, the position of the lever 12 is easily viewed from the large majority of directions around the cylinder valve assembly 1, thus allowing the end user to readily ascertain if the valve 10 is open or closed from a larger number of locations.
Figure 3 shows an alternative cylinder valve assembly 50. As above, the cylinder valve assembly 50 comprises a gas cylinder 52, a valve assembly and a valve guard 70. The valve assembly 60 comprises an actuating lever 62 and an outlet 64.
The guard 70 comprises a base portion 71 and a cantilevered arm 72.
As best seen in Figures 4 and 5, the base portion 71 is generally of concave form and has two openings 75 and 76 provided therein. Although generally of concave fomi, as shown in Figure 3, the large majority of the base portion 71 is located below the valve assembly 60 thereby maintaining access to the valve assembly and outlet 64.
In addition, the base portion 71 comprises a raised side wall 74. The arm 72 extends from the base portion 71 to a distal end 73. A churning knob 80 is located at the distal end 73 of the arm 72. The cantilevered arm 72 is generally of tapered form, tapering from the base portIon 71 towards its distal end 73.
To allow the guard 70 to be fitted to the valve assembly 60 when the valve assembly is in place on the gas cylinder 52, the guard 70 is fabricated in two pieces 91 and 92. Bolt hoies 78 are provided in each half 91, 92 and, in use, the two halves are held in place by bolts 78, The assembled guard 70 thus comprises a spt Une 90. The guard materi& may typicafly comprise, for example, cast metak, plastics or reinforced plastics.
When the valve guard 70 is in place around the valve assembly 60, the side waD 74 is located proximate the ever 62 of the valve assembly (Figure 3). This affords protection to the ever 62 from side impacts whe not unduly limiting the visibflhty of the ever 62. As shown, because the ever 62 projects beyond the side waD 74, the downward or oft" position of the lever 62 can sUD be seen by a user observing the valve assembly 60 from the opposite side of the waD 74.
In USC: opening 75 in the guard 70 is arranged to be located behind the valve assembly 60 to aflow access to a valve inspection point (not shown).
Opening 76 in the guard 70 provides a handle for end users when manipulating the cylinder valve assembly 50. In addition, openings 75 and 76 provide weight savings and material savings, the material saving in particular providing cost savings. If desired the side waD 74 may have an opening to provide an additional grasp point and to provide additional weight saving.
The cantilevered arm 72 resides substantially behind the valve assembly 60 at its proximal end 81 and extends to a position substantiafly above the centreline of the cylinder 52 at its distal end 73. The arm 72 therefore bends forward over the vave assembly 60, This configuration protects the valve assembly 60 from damage in the event that the cylinder valve assembly 50 is dropped of knocked over. The guard 70 is configured so that if the cylinder valve assembly 50 falls forwards or sideways, in the absence of projecting objects, the first point of contact will not be the valve assembly 60 but either the base portion 71 or the arm 72 of the guard 70.
It is possible that the lever 62 may he damaged or broken off if the cylinder valve assembly 50 falls over. However, the guard 70 wifl protect the vave from impacts which may damage the vavo and cad to loss of the valve from the cyUnder 52.
n the arrangement of Figure 3, it is important that the features of the guard 70 &ign with corresponding features of the valve assembly 60. For example wafl 74 needs to be located proximate the ever 62, and opening 75 needs to be located behind the valve assembly 60. To ensure correct alignment, the guard 70 may be provided with an aHgnrnent feature (not shown).
1 wHI be understood that relative terms such as "above", "behind' etc. used in the proceeding description are relative to the valve assembly 60 when in place on the cyUnder 52 during normal use with the cylinder 52 upright.
The front 65 of the v&ve assembly 60 is that closest to the distal end 63 of the lever 62 when the ever 62 is in the downward or "off" position.
It wW be understood that the nvention may be app fled to any type of cyUnder and v&ve arrangement including liquid storage cyfinders.
