Definitions
- the present invention relates to a pressure vessel for storing a compressed gas.
- gas as used herein includes within its scope a gas mixture.
- the gas may be a permanent gas, in which case it can be stored in a pressure vessel entirely in gaseous state, or a non-permanent gas, in which case it may exist under pressure in the storage vessel as a liquid phase in equilibrium with a gaseous phase according to the storage pressure.
- Gas cylinders Pressure vessels for storing compressed gases are of course very well known and are commonly referred to as "gas cylinders" because they conventionally, but not necessarily, have a cylindrical shape.
- a gas cylinder is typically able to store gas at a pressure of up to 200 bar or 300 bar.
- a gas cylinder is conventionally formed as a one-piece vessel, symmetrical about a longitudinal axis, from a suitable steel. The walls of the vessel have a suitable thickness to be able to withstand cycling of pressure from atmospheric pressure to a maximum storage pressure, which as stated above may be as high as 300 bar.
- the cylinder has an axial opening in which is fitted a valve, typically having a brass body with external screw threads that engage complementary screw threads in the mouth of the cylinder.
- cylinder valves There are various different kinds of cylinder valve, but all kinds are able to be opened to permit the controlled discharge of gas from the cylinder and also, when the cylinder is empty, to enable it to be refilled.
- Some cylinder valves have an integral pressure regulator to enable the user to set the pressure at which gas is delivered.
- the cylinder valve may have a port in which a separate pressure regulator may be docked.
- the pressure regulator may include a pressure gauge to indicate the delivery pressure to a user. Such a pressure gauge is not in continuous communication with the interior of the cylinder.
- EP 2 339 222 discloses an arrangement in which a pressure sensor has a continuous communication with the interior of the pressure vessel and a temperature sensor is in thermal communication with the interior of the vessel.
- the signals from these sensors are fed to a controller which displays certain information on the content on a display screen.
- the application is primarily directed to a modern lightweight cylinder which has a plastic shell with handles under one of which the screen is positioned.
- the application also mentions the possibility of applying the principle to a traditional steel cylinder, in which case it suggests incorporating the display screen into the valve assembly or guard. Incorporating the display into the guard is directly analogous to include these in the shell of the lightweight cylinder, although no specific example is given of how this is done.
- a pressure vessel apparatus for the storage of compressed gas comprising:
- a pressure sensor device for sensing the pressure in the vessel, the pressure sensor device being in continuous communication with the interior of the pressure vessel and being adapted to generate a first signal which is a function of the sensed pressure in the pressure vessel;
- thermosensor device for sensing the temperature of the gas in the vessel, the temperature sensor device being in thermal
- a programmable computing device for calculating information concerning the amount of contents in the pressure vessel from the said first and second signals;
- a display screen operatively associated with the computing device for displaying said information;
- the circumferential nature of the collar provides plenty of room to accommodate a larger screen then can be accommodated in the guard.
- the collar is generally a thin-walled plastic structure as to opposed to the guard which is a relatively thick metal structure. It is therefore easier and cheaper to produce a collar which can accommodate a screen and also to attach the screen to the collar. It can be simply and cheaply replaced in the event of a screen malfunction.
- the position of the collar ensures that the screen is protected in both the body of the pressure vessel and the guard itself and it is therefore well placed for protection against accidental damage.
- the apparatus according to the invention is thus on simple inspection of the display screen able to impart to the viewer information about the amount of contents present in the vessel.
- the computing device may be programmed to calculate the mass of gas in the cylinder from the real gas equation. This calculated mass may be compared with the mass of gas in the pressure vessel when full, and a pictorial, graphical or digital display of the information may be made, for example as a position on a full to empty scale.
- the apparatus may additionally comprise a level detector for detecting the level of liquid in the pressure vessel, the level detector being adapted to generate a signal which is a function of the sensed level of the liquid in the pressure vessel and to transmit the signal to the programmable computing device.
- the pressure and temperature sensors may be in the shoulder of the vessel as shown in EP 2 339 222. However, preferably, the pressure and temperature sensors are located within a sensing port or ports in the shut off valve on its pressure side.
- FIG. 1 is a schematic, cross-section of a pressure vessel according to the invention
- Figure 2 is a cross-section through the valve illustrating the pressure and temperature sensors
- Fig. 3 is a schematic cross-section showing a second example of a pressure vessel.
- Figure 4 is a schematic diagram illustrating the electrical components included in the vessel.
- the pressure vessel 2 is a conventional steel or aluminium gas cylinder, or may be made of a seamless composite material.
- a cylinder valve 4 has a body with external screw-threads 5 complementary to threads 6 in the mouth of the cylinder 2 so as to enable fluid-tight engagement to be made between the mouth of the cylinder and the valve.
- the pressure transducer and temperature sensor 7 are located in a ports in the valve 4. This is similar to the arrangement disclosed in US 5,975,121 .
- the pressure transducer and temperature sensor 7 is provided in a lateral port 8 which leads to the main valve bore 9, the flow through which is controlled by valve element 10 and is well known in the art.
- a collar 1 1 Extending around the neck of the cylinder 2 is a collar 1 1 .
- Such collars are well known in the art and are attached to the cylinder to provide safety information and information on the content of the cylinder. This is held in place by the guard 12.
- the collar 1 1 accommodates a display screen device 13 and also houses the computing device described below .
- a cable 14 connects the screen device 13 and computing device with the pressure transducer and temperature sensor.
- the temperature sensor may be integrated into the same housing as the pressure transducer. Alternatively, a
- the temperature sensor may be provided in a separate bore, attached to the external face of the cylinder, or even integrated into the screen device 13. In these latter cases, the temperature sensor will not sense the internal temperature of the cylinder directly. However, by sensing the temperature of the wall of the cylinder, or of the immediately surrounding vicinity, the sensor is able to provide information from which an approximation of the temperature inside the cylinder can be determined. In this sense it can be said to be in thermal communication with the interior of the pressure vessel.
- the valve In order to assemble the device, the valve is fixed in place.
- the collar 1 1 with the screen device 13 in place is placed over the shoulder of the cylinder and the collar is rotated to bring the display into alignment with the pressure transducer and temperature sensor 7.
- the collar 1 1 is then fixed in place by screwing the guard 12 onto the cylinder to hold the collar against the top of the cylinder.
- the cable is then connected to the pressure transducer.
- the cable may be connected before the collar is fixed place.
- the collar may be held in place by a retaining ring 15, which is screwed in place instead of the guard as shown in Fig. 3.
- Fig. 4 The electrical arrangements are illustrated schematically in Fig. 4.
- the previously defined pressure transducer and temperature sensor are designated separately by pressure sensor device 24 and a temperature sensor device 26.
- the pressure sensor device 24 is preferably of a kind based on the flexure of a ceramic membrane, for example, of aluminium oxide. This material has good elasticity and is almost free of hysteresis.
- the upper side of the membrane has a bridge arrangement (not shown) of electric resistors attached thereto. Flexure of the membrane in response to the pressure in the pressure vessel causes the resistors to be deformed with the result that their electrical resistivity varies.
- An input voltage is applied to the bridge and an output voltage dependent on the degree of flexure of the membrane and hence the pressure in the pressure vessel is tapped off from the bridge in a known manner.
- the output voltage is conducted to associated electrical circuits which amplify the voltage and provide a signal representative of the pressure to the display screen device 12.
- the pressure sensor device 24 is generally similar to that disclosed in US-B-6 978 678 to which document the reader is referred for further information.
- the mass of the gas can be calculated from a knowledge of the sensed pressure, sensed temperature, the volume of the pressure vessel, and the composition of the gas with which the cylinder or pressure vessel is filled. If the gas is not a permanent gas, however, and if the part of the gas is present in the pressure vessel in the liquid phase, then performance of such a calculation requires a knowledge of the volume of liquid present.
- the temperature sensor device 26 may also incorporate a level sensor or level sensors (not shown). Alternative level sensing devices can be used, for example, one emphasising sonic sensing of the liquid level.
- the display screen device 13 includes a programmable computing device 40 for calculating the mass of gas in the pressure vessel from the sensed pressure and temperature signals (and, as appropriate, the liquid level) and for feeding signals representing the results of the calculations to the screen 42 of the screen device 22.
- the screen 42 typically utilises light emitting diodes (LEDs) and/or a Liquid Crystal Display (not shown). It may alternatively be an e-ink.
- the display screen device 13 may also house a battery (not shown) for activating the display screen 42. The battery may be disposable or rechargeable and may also be used to provide electrical power to the sensors.
- the computing device 40 may also calculate parameters relating to the mass of gas in the cylinder or pressure vessel.
- the device 40 may be programmed with the mass of gas present when the cylinder was full, and calculate how full the cylinder is at any time, for example, on a scale of 0- 100, 0 being empty and 100 being full. This information can be displayed numerically as a percentage or pictorially . Other calculations may be made. For example, if the gas is intended for use as a shielding gas in electric arc welding, then there may be calculated and displayed the length of time for which gas can be drawn from the cylinder before it runs out. In another example, if the gas is intended for use in filling balloons, the mass of gas present in the cylinder at any one time may be expressed in terms of the number of balloons that can be filled before the cylinder runs out of gas.
- the display screen 42 may be permanently illuminated or may be provided with control buttons such that a particular parameter or parameters will be displayed only when the buttons are depressed.
- the electrical arrangements are illustrated schematically in Figure 4. All requirements for electrical power are met from a rechargeable or disposable electrical DC battery 60.
- the battery supplies the electrical power necessary to operate the pressure sensor device 24 and the temperature sensor device 26.
- the battery 60 also provides the necessary electrical power to operate the display screen device 12.
- the display screen device 13 includes an analogue to digital converter circuit 62 which converts signals from the sensors 24 to 26 into digital form.
- the converter circuit 62 is operatively associated with a programmable microprocessor 64 including a RAM (Random Access Memory) device (not shown) and interposes with an input keyboard 66 and output devices including a liquid crystal display screen 42, a Light Emitting Diode display 68 for providing a visual alarm signal and a buzzer 70 for making an audible alarm signal.
- RAM Random Access Memory
- the voltage provided by the battery 60 may be transformed into a first larger DC voltage by transformer 72 so as to provide electrical power to the sensors 24 and 26 and the analogue- to-digital converter 62, and to a second larger DC voltage by transformer 74 so as to provide electrical power to the microprocessor 64 and the output devices.
- the pressure vessel apparatus is thus able to give the user of a cylinder a visual indication of its contents, that is how full it is, on demand at any time.
