Abstract

A pressurised fluid cylinder with a main axis and having a shut-off valve with a linearly moveable valve element 6. A lever 10 is coupled to the valve element via an eccentric coupling 11 so that rotation of the lever about a pivot axis 33 causes linear motion of the valve element. The cylinder defines a median plane including the main axis x and parallel to the pivot axis. The pivot axis is on one side of the median plane and the end of the lever furthest from the pivot axis is on the opposite side of the median plane when the lever is in a position in which it closes the valve.

Description

A PRESSURISED FLUID CONTAINER
The present invention relates to a pressurised fluid container having a shutoff valve.
In particular, the Invention relates to a pressurised gas cylinder for use, for example, with medical aasses, welding gasses and the like.
Such cylinders are traditional.Iy provided with a shut off valve at the top of the cylinder which is protected by a guard. Fhe valve has a valve element which is moved towards and away from a seat by rotation of a screw mechanism. This consists of a hand wheel with a male screw which mates with a female screw thread in the valve body. The user can therefore open and close the shut off valve by rotating the hand wheel to raise and lower the valve element.
Although such mechanisms are widely used, they suffer from a number of problems. The hand wheel requires multiple rotations in order to rotate it which is time consuming and it is not particularly accessi.hJ..e when the guard is in place. Further, it can he stuck in a fully open or a fully closed position. Although arrows are usually present on the wheel to indicate the direction of opening and closino to the user, it is difficul.t to determine by sight the current cosition of the wheel, such that the user can, for example.
attempt to open an already fully open valve and mistakenly believe the valve to he stuck.
A further difficulty with the fact that there is no clear indication of position is that a user may not fully close a valve as there is no clear indication that the valve has reached the fully closed position, thereby leading to inadvertent leakage from the container, A number of these problems are overcome by using a lever in place of a hand whee.l to impart a Linear force to a valve via an eccentric coupling.
While hand wheels usually close with several revolutions of the wheel, lever oterated valves open and close gas bottles with only a fraction of a revolution of the lever, usually less than 160°. This means that the user must create a higher torque than with the hand wheel. The longer the lever, the lower the force that the user must create in order to operate the valve. However, many cylinders have a valve guard surrounding the valve mechanism. This valve guard places limits on the angle through which the lever can travel as it cannot be obstructed by the valve guard. Also, the bottles are often transported and stored in a close array such that a number of cylinders are immediately adjacent to one another. In some circumstances, the valves are operated whilst the cylinders are still in this array and, again, the valve lever should be designed so that it does not interfere with an adjacent cylinder when it is part a: such an array. This places ±imits on the Length ot the lever. These limitations on the arc of travel and length of SO the lever conflict with the desire to minimise the opening torque.
According to the present invention, there is provided a pressurised fluid cylinder with a main axis and having a shut-off valve, the shut-off valve comprising a valve element which is movable in a linear direction towards and away from a valve seat to selectively close kthe shut-off valve, a lever which is coupled to the valve element via an eccentric coupling so that rotation of the lever about a pivot axis causes linear motion of the valve element, the cylinder defining a median plane including the main axis and parallel to the pivot axis, the pivot axis being on one side of the median plane and the end of the lever furthest from the pivot axis being on the opposite side of the median plane when the lever is in a position in which it closes the valve.
By off-setting the pivot axis with respect to the main axis in this way, the centre of rotation of the lever is effectively behind the axis of the bottle. This effectively moves the arc through which the lever sweeps when opening and closing back into a position from which a longer lever can be accommodated without projecting past the front of the cylinder. This means that a longer lever can be accommodated without interfering with the guard, or with an adjacent cylinder in an array.
Reference above to positional terms such as "behind", "back" and "front" are relative to the median plane with the rearwards direction being the side of the plane which contains the pivot axis and the frontwards direction being the opposite side of this plane.
The off-set pivot axis could be accommodated-ith a linear valve element which moves along the main axis, provided a suitable mechanical link is provided between the pivot axis and the valve element. However -oreferably the linear direction in which the valve element is movable is off-set from the main axis. This enables the pivot axis to he off-set to a reasonable extent, while not unduly increasing the height of the radial footprint of the valve body.
Preferably, a qas flow path is provided through the valve bony, tne gas flow path having a rirst portion on tfle main axas, a. secona portion anglen away tram the main axis and a third portion angled back towards the main axis, the valve element being arranged to selectively close the gas flow path at the third portion. An arrangement which is anqied trst in one nrection and tnen bacic in the opposne direction towards the axis provides the optimal footprint for the valve body.
With this arrangement, the lever can tend towards the dameter or. the cylinaer and cc at leasL 10cm ann preferabiy at least 15cm long, and he constrained to travel through an angle of less than 150°, preferably less than 120° and more preferably less than 90°. The invention allows the use of a longer lever passing through a smaller angle than the prior art..
An exampi.e of a cylinder in accordance with the present invention will now be described with reference to the accompanying drawings, in which: Fig. 1 is a cross-section through the top of. the cylinder and the shut-ott valve; Fig. 2 is a cross-section showing the internal arrangement of the shut-off valve in greater detail; Figs. 3A and 32 are schematic crosssections through a cylinder having a non--oft--set axis included for comparison purposes only and not part of the present invention; and Figs. 4A and 4E are views similar to Figs. IA and 3E of the present The valve comprises a valve body 1 screwed into a pressurised cylinder 2 as is well known in the art A gas outlet path 3 extends up through the centre of the lower part of the valve body 1, before having portion inclined to the left and a further portion incline to the right as shown in Fig. 1. These inclined portions are not necessary for the invention which could equally he applied to a straight axial gas flow path, or any arrangement of gas path.
A residual pressure valve 4 and a geuge S both communicate with the gas outlet path 3 in the pressurised region upstream of valve element S. The valve element 6 is a ring which is designed to seat in a valve seat 7 in the form of a shallow annular qroove surrounding the outlet of the gas outlet passage 3. s shown in P.1g. 1, with the valve element 6 in the open position, communication is opened to a gas outlet B.
-
The valve is opened and closed by the operation of a lever 10 which is connected via an eccentric coupling 11 such as a crank or cam whereupon rotation of the lever 10 is connected via the eccentric coupling U to linear movement of a valve stem 11 and hence the valve element 6 to open and close the valve as described below, The eccentric coupling 11 is coupled to the valve stern 12 by rotatable coupling 13 which will rotate within the valve stem as the lever is rotated but still transmit an axial force to the valve stem.
The valve stem 12 is slidable within a valve sleeve 14 which is screwed into the valve body 2 via complementary screw threads 15. A high pressure seal 16 seals the interface between the valve body 2 and valve sleeve 14. There is also the option of a back up ring 17 as shown in Fig. 2.
The body of the valve stem 12 is made up of a number of components. Closest to the valve element S is a valve element retaining member 20 which retains the valve element 6 and is slidable within the valve sleeve 14 to which it is sealed by high pressure 0-ring seal 21, There is also the option of a back-up ring 22 as shown in Fig. 2.
At the end opposite to the valve element 6, the valve element retaining member 20 is screwed into a pre-load shaft 23. This has an outwardly projecting annular flange 24. A first spring 25, which in this case is a helically coiled spring acts between the valve sleeve 14 and the annular flange 24 to urge the pre-load shaft 23 and hence the valve element 6 into an open position.
On the opposite side of the flange 24, the pre-load shaft is surrounded by second spring 26 in the form a stack of Belleville washers or plate springs for the reasons described below.
At the end of the pre-load shaft 23 opposite to the valve element retaining mechanism 20, it is screwed into a pre-load nut 27 as best shown in Fig. 2. This pre-load nut bears against a washer 28 which sits on top of the second spring 28. The degree to which the pre-load nut 27 is screwed onto the pm-load shaft 23 will determined the biasing force provided by the second spring 26. As can be seen in Fig. 2, a shoulder 29 on the pre-load shaft 23 limits the extent to which the second spring 26 can be compressed.
A slider 30 is attached to the eccentric coupling 13 described above. This is slidable within the valve sleeve 14 and bears on the top surface of the washer 28 as best shown in Fig, 2. It is not positively coupled to the pre-load shaft 23 or pre-load nut 27.
As, the eccentric coupling U pushes the slider 30 into the valve sleeve 14, this force is transmitted via the washer 28, the second spring 26, flange 24 and valve element retaining member 20 in order to close the valve element 6 against the action of the first spring 25 and the fluid pressure. When the eccentric coupling is turned to withdraw the slider 30 from the sleeve 14, this simply releases the -a.-closing force on the valve stem components so that the biasing force provided by the first spring 25, together with the fluid pressure cause the valve to open.
The presence of the second spring 26 allows the mechanism to take up any slack caused by dimensional tolerances within the valve component or by wear of components such as the valve seat 6. For example, if the valve seat 6 wears over time, the biasing force provided by the second spring 26 will force the valve element retaining menther 20 further to the left as shown in Fig. 1 by a force applied by the annular flange 24 and the pre-load shaft 23. As a result of this, the lever 10 can always return to the exact same opening and closing positions even once the valve components wear, and the second spring 26 guarantees the valve element will still close with the desired force.
Further, even if there are dimensional tolerances from one cylinder to the next, the presence of the second spring 26 means that all of these cylinders can have the same opening and closing position such that, if the user is looking across a large number of cylinders, these will all look uniform as their levers will be in the same position. If all of the levers were to close in different positions, this would create uncertainty in the mind of the user as to whether the cylinders were fully closed) and would also look untidy to create an impression that the valves were not well engineered.
An advantage provided by the present invention will now be described with reference to Figs. 3A, 38, 4A and 43. In all cases, the figures show the cylinder 2 with a valve body 1 attached. Also shown is a guard 30 which is fixed to a shoulder on the top of the cylinder to surround and protect the valve body 1. Such guards are generally known in the art. This essentially consists of a hollow metal housing with one or more openings 31 allowing access to the valve actuation mechanism, outlet port and gauge.
Figs. 3A and 38 show closed and open positions respectively the lever 10 which pivots about axis 32 on the main axis X. By contrast, Figs. 474 and 48 are in accordance with the present invention and have the pivot axis 33 off-set from the main axis X in the direction away from the free end of the lever 10.
As can be seen from these drawings, the off-setting of the axis in this way allows for a significant increase in the length of the lever 10 whilst the extent to which it projects beyond the guard 30 remains relatively unchanged.
