Definitions

  • the invention relates to a filling device for filling a closed system, e.g. a heating system, with a filling medium to a predetermined internal pressure, consisting of a pressure reducer connectable on the inlet side to a supply line and on the outlet side via a backflow preventer to the closed system.
  • a filling device for filling a closed system, e.g. a heating system, with a filling medium to a predetermined internal pressure, consisting of a pressure reducer connectable on the inlet side to a supply line and on the outlet side via a backflow preventer to the closed system.
  • Pressure reducers of this type for example the filling group type 2128 from the applicant, are used, for example, for filling a closed heating system and are used to fill this system automatically.
  • the pressure reducer is set to a predetermined pressure and closes when this pressure is reached, so that the pressure in the closed system cannot exceed a predetermined value.
  • the backflow preventer is provided between the outlet side of the pressure reducer and the closed system changes that the filling medium or water from the closed system can be pushed back into the supply line if the inlet pressure of the pressure reducer drops below the internal pressure of the closed system.
  • the known filling device is not constantly connected to the closed system according to existing regulations, but only via a hose line to be removed after the filling process.
  • This has a disadvantageous effect, particularly in the case of larger systems, because the venting process of such systems takes long times, possibly up to 6 months, and during this venting period, filling medium or water must be constantly topped up in the system so that the required pressure within the closed system is maintained. Repeated refilling operations of this type are tedious, and for this reason attempts have been made to automatically fill the closed system in compliance with the legal provisions by connecting an unpressurized water tank, which is controlled by a float valve, to the closed system via a booster pump becomes.
  • a booster pump is relatively complex and also disadvantageous in that a booster pump must be used, although the pressure in the supply line itself would be sufficient to ensure the necessary filling pressure of the closed system.
  • the object of the invention is an automatic filling device to create the type mentioned above, which can be connected directly to the supply line and allows the pressure in the supply line to be used to automatically fill the closed system.
  • this object is achieved in that a pipe separator is arranged between the pressure reducer and the backflow preventer and a pressure-dependent control arrangement is provided for the pipe separator, by means of which the pipe separator can be set into a closed position at a first pressure which corresponds to the predetermined internal pressure of the filled system is, in which the connection between the pressure reducer and the backflow preventer is interrupted, and at a second pressure, which is lower than the first pressure, can be set to a second position, in which the pressure reducer is connected to the backflow preventer via the pipe separator and the Permitted passage of the filling medium to the backflow preventer.
  • the filling device designed according to the invention represents a unitary assembly that uses the pipe separator to establish a connection between the supply line and the closed system.
  • This module can always be left in connection with the supply line and the closed system without the risk that the filling medium is pressed back out of the closed system into the supply line.
  • the interposition of the pipe separator controlled by the control arrangement brings about a safe separation of the supply line from the closed system, if its predetermined Internal pressure is reached.
  • the pipe separator ensures that filling medium is pressed back into the supply line from the filled system if the pressure in the supply line drops below the internal pressure prevailing in the filled system.
  • the figure shows a longitudinal section through the embodiment of the filling device.
  • This consists of an essentially conventionally constructed pressure reducer, which is generally designated 1.
  • This pressure reducer is set to a pressure which is matched to the predetermined internal pressure or filling pressure of the closed system.
  • the structure of the pressure reducer 1 and its function and setting are known and are therefore not described in detail.
  • the pressure reducer On the input side, the pressure reducer is provided with a connecting piece 2, to which a connecting piece 4 is fastened by means of a union nut 3, by means of which the pressure reducer 1 can be permanently connected to a supply line, not shown.
  • a shoulder 5 is firmly connected to the pressure reducer 1, which continues pipe separator described below.
  • a backflow preventer In the free end 6 of the neck 5, a backflow preventer, generally designated 7, is inserted by means of a connecting part 8.
  • the backflow preventer 7 carries at the other end on a connecting piece 9 a union nut 10, through which a connector 11 is held, by means of which the entire filling device can be permanently connected as a uniform fitting to the closed system, not shown.
  • the backflow preventer 7 contains a spring-loaded closing body which is held by the spring load in a closing system in a seat and blocks the backflow preventer 7 against the neck 5 and thus against the pressure reducer 1.
  • the connecting part 8 of the backflow preventer 7 contains a bypass line 13 which bypasses the closing body 12 and opens into an annular chamber 14, in which the internal pressure of the closed system therefore prevails.
  • a separation point 15 is installed, which allows a visual inspection of the space between the pipe separator 20 described below and the check valve 7 and in the usual and therefore not particularly described Is trained.
  • a leak drain pipe 16 branches off from the attachment 5 and is connected in a conventional manner to an existing disposal line.
  • the pressure reducer 1 also carries on one side a not particularly marked setting device of conventional design for setting an off gear pressure, which is matched to the predetermined internal pressure or filling pressure of the closed system. On the opposite side, the pressure reducer 1 carries a control arrangement 40, described in detail below, for controlling the pipe separator 20.
  • the approach 5 of the pressure reducer 1 is designed so that it serves as a housing for the pipe separator 20.
  • This pipe separator 20 consists of a pipe 21 which is closed on one side and which is inserted in a sealing manner in the attachment 5 on the pressure reducer 1.
  • At the closed end of the tube 21 through openings 22 are formed in its side wall, three of which can be seen in the figure.
  • An annular piston 23 is displaceable on the tube 21 against the force of a spring 24.
  • the head 25 of the annular piston 23 faces the pressure reducer 1; the spring 24 acts on the side of the head 25 facing away from the pressure reducer 1 and is supported on an abutment 26 which is held on the extension 5 in the vicinity of the separation point 15.
  • the annular piston 23 also has a recess 27 in its wall and forms an annular gap 28 between the recess 27 and the through openings 22 in the tube 21 which is closed on one side.
  • the pipe separator 20 is shown in its closed position in the figure. In this position, the annular piston 23 lies in a sealing manner against the tube 21, which is closed on one side, so that the through openings 22 of the tube 21 are closed.
  • the connecting part 8 of the backflow preventer 7 contains on the opposite side of the pipe separator 20 a recess 29 which on the ring-shaped gene piston 23 of the pipe separator 20 is adapted and this in its second or open position.
  • the recess 29 is provided with sealing means 30, by means of which the annular piston 23 is sealingly inserted into the recess 29 in the second or open position.
  • the control arrangement 40 consists essentially of control valves and a differential pressure transmitter for controlling the control valves; the control arrangement 40 is arranged on the pressure regulator 1 on the side opposite the adjusting device.
  • the differential pressure transmitter 41 consists essentially of two chambers 42, 43, which are separated from one another by a movable wall 44 in the form of a membrane.
  • the chamber 42 facing away from the pressure reducer 1 is connected to the outlet side of the pressure reducer 1 via a connecting line 45 shown in broken lines.
  • the chamber 43 is connected to the ring channel 14 in the connecting part 8 of the check valve 7 via a connecting line 46 shown in broken lines.
  • the differential pressure sensor 41 is fastened in a sealing manner to a further extension 48 of the pressure reducer 1 by means of a union nut 47.
  • the movable wall 44 carries a plate 49, to which a control rod 50 is fastened, which extends sealingly into the interior of the further extension 48 through a sealing body 51.
  • a valve seat body 52 is formed in the interior of the pressure reducer 1 on the outlet side thereof in the further extension 48.
  • On the valve seat body 52 is located on the side facing away from the pressure difference transmitter 41 a valve seat 53 of a control valve with a spring-loaded valve body 54.
  • the valve body 54 is closed by a compression spring which is supported on an opposite part of the pressure reducer 1, in the exemplary embodiment on its single-seat valve held at its valve seat 53.
  • the valve body 56 is under the action of a tension spring which is arranged on the valve seat body 52 and the valve body 56 in a closed contact with its valve seat 55 holds.
  • An axial bore 57 extends through the valve seat body 52, from which a control line 58 branches off between the valve seats 53 and 55, which connects the axial bore 57 and an annular space of the extension 5 and on a side opposite in the head 25 of the annular piston 23 of the pipe separator 20 opens into the annular space 60.
  • a relief line 59 extends from the further extension 48, which extends essentially parallel to the control line 58 and extension 5 and extends to the leakage drain pipe 16.
  • the control rod 50 of the differential pressure sensor 41 extends sealingly but slidably through the valve body 56 and the valve seat 55 of the relief valve and through the axial bore 57 of the valve seat body 52 and carries at its free end a control body 61 which cooperates with the valve body 54 of the control valve.
  • filling medium can pass through the pressure reducer 1 and the tube 21 closed on one side and its through openings 22 into the interior of the annular piston 23 and from there through the recess 29 in the connecting part 8 of the check valve 7 while adjusting its closing body 12 into the closed system flow.
  • the filling process continues until pressure equalization between the outlet side of the pressure reducer 1 and the internal pressure of the closed system is established.
  • the valve body 56 of the relief valve in which the control rod 50 can be displaceably moved in a sealing manner, remains in the position shown, that is to say in closed contact with the valve seat 55 of the relief valve.
