Definitions

  • the present invention relates to a pressure-tight connection arrangement according to the features of the preamble of claim 1.
  • Pressure-sealed connection arrangements are used in over-or under-pressure devices to prevent leakage of the pressurized medium into the environment or entry of ambient air into the device ,
  • line arrangements in which individual line sections are connected by means of pressure-tight connection arrangements in order to prevent escape of the conducted medium into the environment or an entry of ambient air into the device.
  • filter systems serve, for example, the filtering of dust particles from an air stream.
  • filter systems have filter cartridges containing the actual filter. Since a filter cake forms over time, regular cleaning and / or replacement of the filter element is necessary. However, the filter system can not be used during cleaning or replacement. Therefore, it is desirable to be able to perform the cleaning or replacement as quickly as possible.
  • Clamping screws are based.
  • two sealing elements in the form of conventional sealing rings are arranged between two connecting elements.
  • the two connecting elements have a common peripheral contour, which may be rectangular or round, for example.
  • Between the sealing elements of the frame of a filter insert is arranged. In the assembled state, a sandwich is thus formed from a connecting element, a sealing element, the frame, the further sealing element and the further connecting element, in this order.
  • clamping screws are mounted along the peripheral contour. These clamping screws have two hooks which engage around the two connecting elements. Subsequently, the hooks can be moved towards each other by means of a screw, whereby the sandwich composite is pressed together.
  • the sealing elements nestle to the fasteners and the frame and the connection is sealed.
  • the object of the invention is to provide a pressure-tight connection arrangement which reduces the loss of time in the opening and closing of the connection.
  • the pressure-tight connection arrangement has two connecting elements, at least one sealing element and at least one retaining element.
  • the connecting elements have mutually facing inner sides.
  • the at least one sealing element is arranged between the inner sides.
  • the at least one retaining element prevents the connecting elements in a holding state from moving away from each other.
  • At least one sealing element is designed so that it can exert an adjustable force on the two inner sides. Unlike the prior art, this force is thus not set starting from the holding elements.
  • the retaining elements serve rather as a stop.
  • the at least one sealing element is pressed against the insides.
  • the connecting elements try to move away from each other, which hinders the retaining element, however.
  • the at least one sealing element thereby seals the connection.
  • the connectors need not be completely prevented from moving away from each other.
  • the holding elements ensure that a stop is provided for both connecting elements, against which they come while moving away from each other.
  • An essential advantage of this arrangement is that the force does not have to be applied and adjusted to the holding elements. Often a variety of holding elements are used, which is why it is very time-consuming to apply force to each of these holding elements and adjust. At least one By contrast, the sealing element can be applied to the force for the entire connection in one step.
  • the at least one sealing element is an inflatable seal and the force can be applied pneumatically and / or hydraulically to the two inner sides.
  • An inflatable seal has a cavity into which a medium can be introduced under pressure. This inflates the seal. It nestles against the inside of a connecting element or on both inner sides of the connecting elements.
  • sealing elements If a plurality of sealing elements are provided, it is possible to design all sealing elements or only individual ones in such a way that they can exert an adjustable force on the two inner sides.
  • the connecting elements When used as intended, the connecting elements are arranged with the at least one sealing element between their inner sides for producing the pressure-tight connection. Subsequently, the at least one holding element is arranged in the holding state. Finally, the sealing element exerts a force on the inner sides of the connecting elements, in particular by increasing the internal pressure of the sealing element designed as a swelling seal. By virtue of this force and by the retaining elements which prevent the connecting elements from moving away from one another, the at least one sealing element conforms to an inner side or both inner sides. In this way, the connection is sealed.
  • the sealing elements As an alternative to the formation of the sealing elements as an inflatable seal is a mechanical action on the sealing elements into consideration. Due to the elasticity of the inflatable seal, strong compression in one area leads to expansion in other areas of a sealing element. In this way, a force can be exerted on the insides.
  • the retaining element prevents the connecting elements in the holding state by means of their insides opposite the inner sides of it to move away from each other. It is particularly advantageous if the at least one holding element in the holding state comprises the connecting elements at least partially positively. The connecting elements are prevented in this way from excessive disengagement without the risk of slipping of the retaining elements threatens.
  • two sealing elements are provided.
  • a sealing element is advantageously arranged in each case in the region of each inner side of the connecting elements. This arrangement ensures that the sealing elements securely seal at the contact surfaces with the insides. Between them, the sealing elements can seal via direct contact or an intermediate element. It is also possible to form the sealing elements with mutually complementary surface structures, so that they engage in the sealing. In this way, a labyrinth seal effect is additionally achieved.
  • the use of more than two sealing elements is possible.
  • Another possibility consists in the arrangement of two sealing elements between the inner sides in force acting direction, wherein an intermediate element is arranged between the sealing elements.
  • the sealing elements then each seal against a connecting element and the intermediate element.
  • the intermediate element may for example be part of a filter system, a round filter, a rectangular filter, a filter cartridge, a container and / or a cyclone.
  • a sealing element can then be designed as an inflatable seal and one as a conventional seal, for example as a round seal.
  • a sealing element of the composite is clamped with the connecting elements and the second inside nestles against the conventional seal.
  • the force generated thereby and the obtained seal may be sufficient.
  • the at least one retaining element is attached to at least one of the connecting elements in such a way that it can only be removed up to a limited distance.
  • This attachment can be realized for example by a cord.
  • the fastening prevents the retaining elements from being lost when the pressure-tight connection arrangement is opened.
  • the at least one retaining element is displaceable by means of a mounted joint attached to at least one of the connecting elements.
  • the joint allows a tilting of a retaining element to the connecting elements.
  • the sliding bearing allows a linear retraction of a holding element of the connecting elements. In this way, the holding elements can be removed when opening the connection in a simple manner.
  • the retaining elements for closing in a replicable movement can be moved to its closed position.
  • an attachment by means of a stationary joint is possible.
  • the holding elements can then be tilted during the opening and closing of the connection from or to the holding state.
  • holding elements which are arranged along a straight sealing edge can be connected to one another. This is the case with rectangular filters, for example.
  • a plurality of holding elements can be simultaneously brought into the holding state and at the same time removed from this holding state. This significantly reduces the time required to open and close the connection.

  • the fixing device advantageously has at least one magnet and / or at least one spring with a pressure piece and / or a bevel and / or a reduction mechanism. If the holding element has a bevel, then the application of the force by the sealing elements leads to a self-holding effect, since the holding elements are increasingly held in the holding state the farther the connecting elements move apart.
