Definitions

  • the invention relates to a gas storage with an outer and an inner membrane, wherein the inner membrane partially surrounds a variable gas storage space, and with a device for measuring the gas storage space filling level, which comprises a sensor holder and a level sensor which is mounted on the sensor holder, wherein in the outer membrane, a membrane opening for the device for measuring the gas storage space filling level is provided, and wherein the sensor holder is connected via a connecting element with the opening edge of the membrane opening.
  • a gas reservoir is shown with a closable external passage opening, which is delimited by an annular flange, and is suitable for carrying out level measurements.
  • a measuring device for level measurement or a connecting element for such a measuring device are not described in this document.
  • the object of the invention is therefore to provide a gas storage of the type mentioned, for which said disadvantages are not present
  • the connecting element is formed by a hose, wherein an end opening of the hose is connected to the opening edge of the diaphragm opening and attached to the other end opening of the hose, the sensor holder with the level sensor, so that when using the existing between the inner membrane and the outer membrane support pressure spans the tube over the diaphragm opening and thus the level sensor is positioned at a distance from the diaphragm opening.
  • the thus formed tubular connecting element is characterized by cost-effective production, which can be done by means of a flexible material which is much lighter than metal and processed in a simple manner can be.
  • Prerequisite here is the gas and pressure-tight training of the hose and its connection points with the diaphragm opening on the one hand and the sensor holder on the other hand, because otherwise the support pressure between the outer and inner membrane can not be maintained.
  • the transport and assembly simplify significantly, since the invention designed tube is much lighter than the conventional stainless steel diaphragm dome.
  • the sonic performance can be significantly improved, since due to the flexible Schlauchförm the noise is low.
  • the fill level sensor may be an ultrasonic sensor, wherein the length of the hose is greater than the blocking distance of the ultrasonic sensor.
  • this blocking distance in conventional stainless steel domes was a hindrance to the measurement.
  • this disadvantage can be overcome insofar as the inner membrane can be guided up to the outer membrane, since the blocking distance can be bridged by appropriate adaptation of the hose length through the hose.
  • the usable volume of the gas reservoir according to the invention is thereby increased.
  • the hose may be formed of a flexible material, preferably a fabric-reinforced plastic film which is formed tubular along a longitudinal weld.
  • a fabric-reinforced plastic film which is formed tubular along a longitudinal weld.
  • the tube is formed of the same material as the outer membrane.
  • the hose may also be e.g. be cylindrical.
  • the membrane opening is circular and bounded by an annular flange which is connected to the outer membrane , And that the one end opening of the hose is sealingly secured by a clamping ring on the annular flange.
  • another form of membrane opening of the outer membrane is also included in the scope of protection.
  • a simple attachment of the sensor holder to the inventively designed hose is achieved in that the sensor holder is formed from a circular plate and the level sensor is arranged in the center of the circular plate.
  • the plate edge can be permanently and pressure-tightly connected via a flange construction with the end of the tube remote from the outer membrane.
  • the other end of the hose connected to the sensor support may be connected to an annular flange on which the circular plate is mounted with the level sensor.
  • Other geometrical shapes of the sensor holder and other types of connection between the sensor holder and the hose may also be provided within the scope of the invention
  • hose according to the invention from a flexible material allows an improvement of the acoustic properties of Medstandmeßvorraum, whereby an improved reproducibility of the measurement results.
  • An additional improvement according to a further embodiment of the invention consist in that the circular plate is formed of plastic, which reduces the disturbing sound reflections in the measurement.
  • Fig. 1 and Fig. 2 show a gas storage 10 with an existing in its interior gas storage space 20, which is partially surrounded by an outer membrane 1, which is spanned in the form of a three-quarter sphere starting from a bottom foundation 11.
  • a variable inner membrane 2 is provided, which may assume a different extent depending on the amount of gas contained in the gas storage 10.
  • the gas supply and discharge lines and other details are not shown.
  • a pressure-controlled support volume or an air volume in a gap 15 between the outer membrane 1 and the inner membrane 2 provides for expansion or contraction of the inner membrane 2 for a balance.
  • shape of the gas storage 10 is merely illustrative and may also be in another embodiment with an inner and an outer membrane.
  • a device for measuring the gas storage filling level 41 is provided, which monitors the distance between the inner membrane 2 and the outer membrane 1.
  • Fig. 3 shows a known attachment of the device for measuring the gas storage level 41, which has a level sensor 42 which is mounted on a sensor holder 59, which in turn connected via a cylindrical connecting element 56 made of metal, eg stainless steel by means of a flange construction with the opening edge of a diaphragm opening 40 is.
  • Fig. 4 shows the intended for the gas storage 10 according to the invention attachment for measuring the gas storage level 41, wherein the connecting element 56 'is formed by a hose 46.
  • An end opening of the tube 46 is connected to the opening edge of the membrane opening 40 and at the other end opening of the tube 46, the sensor holder 59 is attached to the level sensor 42, so that when using the existing between the inner membrane 2 and the outer membrane 1 support pressure the tube 46th spans over the diaphragm opening 40 and thus the level sensor 42 is positioned at a distance from the diaphragm opening 40.
  • the tube 46 is formed of a flexible material, preferably a fabric-reinforced plastic film, which is formed tubular along a longitudinal weld.
  • the tube is formed of the same material as the outer membrane.
  • the level measurement by means of acoustic measurement of the distance between the outer and inner membrane 1, 2 based on the measured transit times of emitted and reflected sound wave, so that in the illustrated embodiment, the level sensor 42 is an ultrasonic sensor, wherein the length of the tube is greater than the blocking distance of the ultrasonic sensor is.
  • the distance measurement can also be performed with other known, eg optical sensors.
  • the tube 46 is conical, wherein the diameter of one end connected to the opening edge of the membrane opening 40 is greater than the diameter of the other end connected to the sensor holder 59. It may be the tube 46 but also cylindrical or in any other suitable form.
  • the membrane opening 40 is circular and limited by an annular flange 50 which is connected to the outer membrane 1 by the circularly recessed at this point membrane 1 beaten around the flange 50 and the membrane edge region on the underside of the outer membrane 1 welded is.
  • the one end opening of the hose 46 is sealingly secured by a clamping ring 51 on the annular flange 50.
  • a clamping ring 51 on the annular flange 50.
  • Other types of fasteners are known to those skilled in the art and can be applied accordingly.
  • Fig. 4 shows the present during operation of the gas storage, stretched by the support pressure position of the hose 46, in which the level sensor 42 is disposed just above the diaphragm opening 40.
  • the sensor holder 59 is formed of a circular plate 57, wherein the level sensor 42 is disposed at the center of the circular plate 57, which is made of plastic.
  • the other end of the tube 46 connected to the sensor holder 59 is connected to an annular flange 58 on which the circular plate 57 with the level sensor 42 is mounted.
