Definitions

  • Such a closure device and a vacuum sewage system are from the WO 01/25632 A2 known.
  • Vacuum or vacuum sewage systems or systems for drainage comprising a vacuum or vacuum line, to which on the one hand at least one vacuum or vacuum source and on the other hand can be connected via suction valves to waste water collection points such as collecting shafts for the batchwise suction of waste water and air.
  • waste water collection points such as collecting shafts for the batchwise suction of waste water and air.
  • Vacuum sewage systems are mainly used as pure sewage systems.
  • the wastewater usually flows freely from buildings into wastewater collection rooms and shafts.
  • a suction valve arranged between the collecting space and the vacuum line is opened for a period of time via a trigger and a control.
  • the connection between the collecting space and the vacuum line can be referred to as a connection line.
  • the wastewater charge and a certain amount of air are sucked into the vacuum line through the opened suction valve.
  • the control arrangement via which the suction or shut-off valve is in turn opened or closed, it is necessary for the former to be acted upon by the pressure prevailing in the vacuum line.
  • the control arrangement and shut-off valve are usually arranged directly in the area of the connection between the collecting container and the vacuum line, and preferably in a closable container embedded in the ground, the pressure is drawn from the connecting line, which runs between the shut-off valve and the vacuum line.
  • the connecting line has an intermediate piece, in particular with a Y geometry, which is arranged within the protective container.
  • the branch of the intermediate piece which opens into the sections of the connecting line to be connected, is closed by a closing device, preferably in the form of a stopper, in which opens a connection that leads to the control arrangement.
  • a closing device preferably in the form of a stopper, in which opens a connection that leads to the control arrangement.
  • the sealing plug can be closed on the line side via a check valve, preferably in the form of a membrane.
  • the present invention is based on the object of developing the arrangement of the type mentioned at the outset in such a way that, regardless of the prevailing temperatures, water cannot penetrate into the region of the closure device which is shut off by the non-return valve and thus into the elements connected to it, such as the control arrangement and shut-off valve can take place.
  • the closure device has a tubular or tubular section which extends in the connecting line and which has the check valve at the end.
  • the closure device is extended to such an extent that the check valve runs in areas that are frost-proof.
  • the tubular or tubular section projects into the connecting line or an intermediate piece connecting a section of the connecting line to such an extent that it is flushed with wastewater to be extracted. Because this is usually is heated or always has temperatures that are above freezing, it is additionally ensured that the check valve cannot freeze.
  • tubular or tubular section this is an element through which air can flow, which on the one hand is tightly connected to the closure device and on the other hand has a check valve on the end which ensures that liquid is not can flow to the control arrangement or the suction valve via the closure device.
  • the shape of the tubular or tubular section can be any. In particular, however, it is provided that the section is composed of one or more conical sections, which ensures that condensate occurring in the interior can flow in the direction of the check valve.
  • the tubular or tubular section can have an overall conical shape or can consist of conical sections of different cone angles and lengths.
  • the check valve is in particular a beak check valve, which preferably consists of elastomer material.
  • a flexible element is provided which, in the sealing or closed position, has the geometry of an isosceles triangle in a first side view and the geometry of a square in a side view offset by 90 °.
  • the beak check valve comprises a hollow cylindrical base section, from which, when the check valve is in the closed position, two diametrically opposed hollow cylinder sections with a triangular geometry in side view of the check valve each have a tip, which are connected by at least externally flat sections which are connected in the region of a straight line connecting the tips of the hollow cylinder sections are separated.
  • the edges running along the straight line are designed in particular as sealing lips.
  • the closure device itself is preferably designed as a hollow plug and has an average U-geometry with bottom and peripheral walls, the outer surface of which spans a cone.
  • the branch which can be closed via the closure device, is preferably a pipe section of an intermediate piece of the connecting line having a Y geometry, the branch extending in an extension of a section of the connecting line which is sealed off from the intermediate piece by a seal, such as a cone sealing ring.
  • a seal such as a cone sealing ring.
  • the vacuum sewage system of the type mentioned at the outset is characterized in that the closure device has a tubular or tubular section which has the non-return valve at the end, which extends into the connecting line.
  • the check valve is thus located in the frost-proof area of the vacuum sewage system.
  • the branch starts from an intermediate piece of the connecting line that has a Y geometry. Intermediate piece and adjacent section of the connection or waste water line are connected by a seal such as. B. sealed a cone sealing ring.
  • the branch which can be shut off by the closure device, such as a stopper, extends in the extension of the section of the connecting line, the tubular or tubular section having the check valve at the end preferably running behind the seal.
  • the tubular or tubular section having the check valve is preferably connected to the closure device.
  • An integral training is also possible.
  • the section should be flexible to an extent that there is a certain degree of mobility without being compressed in the longitudinal direction, as a result of which the sewage pipe or the intermediate piece could possibly be blocked.
  • the cross section of the tubular or tubular section should be matched to that of the waste water or connection line or the intermediate piece in such a way that an undesirable reduction in cross section, which would lead to increased flow resistance, does not occur.
  • Vacuum or vacuum sewage or drainage systems or systems are mainly used as pure dirt sewers.
  • a section of a corresponding vacuum sewage system can be seen purely in principle, which comprises a sawtooth-shaped vacuum line 13, ie having high points 10 and low points 12, which can be connected to a large number of house connections.
  • the vacuum line 13 is composed of sections of different height profiles in order to open into a main collecting tank, not shown, from which the waste water is fed to a sewage treatment plant. From the vacuum line 13 can also start from high points 10 inspection tubes 22, which can be closed on the surface by means of plugs 24.
  • the plugs 24 can be arranged in boxes which can be closed by means of a lid or a cap 26.
  • a house connection 50 which comprises a shaft body 52, which may be accessible.
  • a collecting tank 14 to which waste water usually flows in free fall from one or more houses.
  • the waste water is drawn into the vacuum line 13 via a line 16 and a connecting line 18 when a shut-off or suction valve 56 in the house connection shaft 50 is opened.
  • the shut-off valve 56 is switched over via a control arrangement 54, as exemplified in FIG DE-A-43 36 020 is described.
  • the connecting line 18 opening into the vacuum line 13 is connected to the shut-off or suction valve 56 via an intermediate piece 57 having a Y geometry, specifically with its outlet on the downstream side.
  • the intermediate piece 57 has a section 58 to be referred to as a branch, which extends in the extension of the section of the connecting line 18 opening into the intermediate piece 57.
  • the branch 58 is closed by a sealing plug 60, from which a line 62 leads to the control arrangement 54 in order to pressurize it to switch over and thus actuate the shut-off valve 56.
  • a line 64 extends from the control arrangement 54 and opens into the shut-off valve 56.
  • the function and structure of the control arrangement 54 and the shut-off valve 56 are sufficiently known.
  • An example is the WO-A-01 25632 referenced, the content of which is expressly referred to.
  • the connection to the line 62 passing through the sealing plug 60 can be shut off via a check valve 100 which, according to the invention, is positioned such that even at low temperatures in the Freezing is not possible in the area of the house connection shaft 50.
  • the check valve 100 is positioned frost-proof.
  • the sealing plug 60 is connected to a tubular or tubular element 102, which can also be an integral part of the sealing plug 60.

  • the check valve 100 starts from the end of the tubular or tubular element 102 and is therefore located behind the seal 104.
  • the tubular or tubular element 102 is composed of an upper section 103 running on the sealing plug side and a lower section 105 running on the check valve side. Both sections 103, 105 have a conical shape, the conical angle of the upper section 103 being greater than that of the lower section 105. Furthermore, the length of the lower section 105 is preferably 2 to 6 times longer than that of the upper section 103 running on the plug side.
  • the check valve 100 can be formed integrally with the tubular or tubular element 102.
  • the conical shape or conical sections 103, 105 of the tubular or tubular element 102 results in the advantage that condensate formed can flow along the inner surface of the tubular or tubular element 102 in the direction of the check valve 100, so that when the valve 100 is opened suction takes place. This ensures that liquid cannot get into the control arrangement 54.
  • the check valve 100 can in particular be a beak check valve which comprises a hollow cylindrical base section 106 which is tightly connected to the end of the tubular or tubular element 102.
  • the check valve 100 consists in particular of elastomer material.

  • the check valve 100 in the closed position has the geometry of an isosceles triangle in a first side view and the geometry of a square in a second side view which is offset by 90 ° to the first side view.
  • the beak-shaped geometry of the check valve 100 ensures that if water should flow back through the connecting line 18 in the opposite direction of flow, the check valve 100 is tightly sealed, so that the sealing plug 60 and the line 62 are connected by an L-shaped connecting piece 63 goes out, water can not get into the control arrangement 54.
  • check valve 100 does not necessarily have to be designed as a beak check valve.
  • Other suitable non-return valves are also possible, the non-return valve 100 being an integral part of the tubular or tubular element 102 and with it, for. B. can be produced by spraying as a unit.
  • the sealing plug 60 which is designed as a hollow plug, has a bottom wall 108 receiving the connecting piece 63, from which a peripheral wall 110, which extends into the branch 58 and has a hollow cylinder geometry, extends, the outer surface 112 of which spans a cone.
