The invention relates to a one designed with a shut-off device Safety device that is to be installed in lines used to convey liquid or gaseous media.

Both when filling bathtubs or other open containers, for example, as well as when filling the container from Washing machines, dishwashers or the like. The problem occurs again and again that either by carelessness of person supervising the filling process or as a result Failure of the Steue.rorganen associated with such machines, the container in question is too large a liquid or also amount of gas is supplied and by the overflow of the excess liquid or the escape of the excess Gas damage occurs. The same can of course also apply to the containers of these machines as well as the lines themselves a leak occurs or even a bursting of any hoses that supply the medium take place.

The invention is therefore based on the object of providing a means of conveying liquid or even gaseous media create a safety device to be installed in the lines that serve, which causes a shut-off of the line in the event of a possible damage, all the more serious consequential damage from the outset to exclude.

This object is inventively achieved in that the shut-off of this safety device responsive ^e IUF the produced during passage of the medium pressure drop and this is associated with a likewise responsive to the pressure drop, an allowable flow rate limiting and cooperating with the shut-off delay device, both at full and only partial withdrawal of the intended flow rate can be reset, which is preferably done automatically. As a result of this combination of a shut-off device with a delay device and the resettability of the same, it is possible, for example, to periodically supply a washing machine or a dishwasher with a predetermined amount of water during the program without the shut-off device of the safety device already being activated. Is now at the consumer or another point of the line downstream of the safety device

'In addition, liquid continues to be removed, which can either happen unintentionally or is caused by possible damage, so the shut-off element of the safety device interacting with the delay device responds and closes its flow opening to the downstream consumer.

t In a particularly advantageous design the interior of a hold piece and a discharge connection having two-part device is convenient serving by extending over the entire cross section of the partition wall in a pre-chamber and the inclusion of the delay means

Delay chamber divided, then these two chambers are again connected to one another by an inlet valve arranged in the partition.

In particular, to allow easy cleaning of one in the antechamber To enable the inlet screen located, it is advantageous if the one having the outflow nozzle Housing part housed components together with this and the partition wall carrying the inlet screen from the other component are detachable.

Furthermore, the cooperating with the delay device, in the area of the outflow opening of the delay chamber arranged shut-off device expediently a support plate with flow openings, the edge of which is back on the edge one supported on the inside of the delay chamber, surrounding the outflow opening of the same and in the axial direction evasive support element is seated. Furthermore, a preferably conical, in one is on this support plate Valve seat protruding valve cone molded or otherwise attached, which releases the flow opening as soon as the Support plate and with this together with the valve cone as a result of the pressure drop, an axial displacement is imposed will.

The support element serving as a counter bearing for the support plate can be designed as a helical compression spring. But it is also possible that this support element consists of a consists of elastic and thus resilient material due to its internal stress and is funnel-shaped, where it then sits firmly with its reduced part in the outflow opening located in the housing part and the dem Has valve cone associated valve seat.

collectively screw the two housing parts 1 and 2 through a collar 13 formed in the housing part 1 firmly against the the edge 10 of the partition 7 seated on the support ribs 11 is pressed.

In addition to any in the liquid or gaseous medium flowing in the direction of arrow 14 To keep dirt away from the main components of the device is to clip the influence 5 facing On the side of the partition 7, a frame designated by 15 is arranged, which again supports the storage of a preferably easy releasable and thus also exchangeable inlet screen 16 is used.

So that the medium flowing into the antechamber 8 can now also continue to enter the delay chamber 9, FIGS the partition 7 with 17 designated flow openings incorporated, one of which is made of an elastic material existing valve plate 18 is assigned, which is fixed with its edge 19 in its rest position shown in FIG sealingly rests against the partition 7 opposite it.

k In addition to this through the flow openings 17 and the The inlet valve formed by the valve plate 18 is a further shut-off element designated by 20 in the area of the outflow connector 6 provided, which should always take effect when the predetermined flow rate is reached. This shut-off device 20 has a support plate designated by 21, in which flow openings 22 are incorporated. This support plate 21 sits tightly sealing on the edge 23 of a '". Made of an elastic and thus as a result of its internal stress resettable material existing funnel-shaped support element 24, which again with its sleeve-like, reduced part 25 in the outflow opening surrounded by the edge 26 of the device part 2 is fitted, this.

Edge 26 then engages in an annular groove machined in part 25. In the aforementioned support plate 21 this The shut-off element 20 is also designated as 28 Shaped valve cone to which a valve seat 29 of the support element 24 having a similar inclination is assigned is. Sarüberhinaue another cap-like valve cone 31 is arranged on the end face 30 of this valve cone 28, which is connected to the valve cone 28 by means of a Met 32. This valve cone 31 forms together with the valve seat 33 opposite it, a check valve, which prevents the backflow dee in the direction of arrow 34 from the outflow nozzle 6 escaping medium.

Between this shut-off element 20 and the partition 7 is the delay device that cooperates with this shut-off element 35 ang® © his t. This device 35 exists from a cap-like shell 36 and a serving as a control member, this shell 36 covering and also cap-shaped designed membrane 37, which in its in the Pig. 1 is in the rest position shown in this shell 36. In the An annular groove 39 is incorporated into the outer edge 38 of this membrane 37, into which the shell edge 40 engages. the The membrane 37 sits together with the shell 36 by means of its edge 38 on spaced apart, on the inside of the housing part 2 integrally formed radially projecting support ribs 41, between which there are flow channels 42, which allow the passage of the medium from the part 43 of the delay chamber 9 into the part 44.

and the interior space 48 surrounding the membrane 37 produces. At the same time, this pipe socket 46 also serves as a bearing for the one belonging to the above-mentioned inlet valve Valve plate 18.

In is adjacent to the previously treated pipe socket 46 the tray bottom 45 also labeled 49 Incorporated reflux opening which can be shut off by an opposing membrane 50 serving as a return valve. This piping membrane 50 sits with its edge 51 in a recess 52 incorporated in the partition 7 and engages with its opposite to the return flow opening 49 Middle part 53 through a recess 54 located in the partition 7. The membrane 50 is held in place doing in the in the pig. 1 represented catfish by the screen frames already discussed above 15 *

The mode of action of this safety device β according to the invention is as follows. If the safety device is, for example, in the feed line of a washing machine, a dishwasher or any other consumer switched on and all aba organs on the consumer side are closed, so there is in the inlet connection 5, the prechamber 8 of the delay chamber 9 the normal Hötzdruck. In the outflow nozzle 6, however, there is a somewhat lower level Pressure, whereby the pressure difference existing compared to the network pressure is determined by the closing pressure of the valve cone 31 determining intrinsic stress of the support element 24 is caused. All components of this device are in your in the? lg. 1 rest position shown, the edge 19 of the valve plate 18 with a slight internal stress on the . Partition wall 7 rests and thus interrupts the connection existing through the flow openings between the antechamber 8 and the delay chamber 9. A pressure equalization between

-9- - -00983d / 0d46

- 9 - 10.3.1969

the prechamber 8 and the delay chamber 9 takes place via the metering bore 47, the pipe socket 46 and the Room 48 and the return port 49.

Wiaaänun a shut-off device downstream of the safety device, For example, a solenoid valve or a manually operated valve is opened or arises Damage causing a leakage between this solenoid valve and the outflow connector 6 takes place in the outflow connector 6 an increased pressure drop. Since, however, in the delay chamber 9 in relation to the interior of the discharge nozzle 6 an increased overpressure herrecht, the associated with the shut-off device 20 is due to this overpressure [Drag plate 21 together with the two valve cones 28 and 31 against the internal tension of the elastic support element in the direction of arrow 55 in that shown in FIG Passage position in which the valve cone has lifted from its seat 33. This is an outflow of the The medium located in the delay chamber 9 in the direction of the arrows 56 is possible.

With the outflow of the medium located in the delay chamber 9 through the open shut-off element 20, however, also occurs in the delay chamber 9 a pressure drop, so that now as a result of the acting through the flow openings 17 Overpressure of the edge 19 of the valve plate 18 in the in the Pig. 2 lifts off from the partition 7 and a further inflow of the medium located in the antechamber 8 into the delay chamber 9 is allowed.

At higher flow rates would be determined by the flow openings 17 as a result of the reduction Flow cross-section already a pressure drop overcoming the internal stress of the control diaphragm 37 in the delay

chamber 9 arise, with smaller Durchflußgeaöhwixiditäten on the other hand, this reduction in cross-section is not sufficient. In order to still achieve the required pressure drop, the valve plates 18 cooperating with the openings 17 provided, which requires an opening pressure that corresponds at least to the maximum bias of the control membrane 37, if this your in the pig. 3 has assumed the end position shown in dashed lines. However, before this opening pressure is reached the membrane 50 must have securely closed the reflux opening 49 in the shell 36 «,

As has already been mentioned above, the interior space 48 surrounded by the shell 36 and the membrane 37 is directly connected to the antechamber via the nozzle bore 47 of the pipe socket 46. Since there is an overpressure in this pre-chamber 8 compared to the delay chamber 9, this overpressure now causes the diaphragm middle part 57 to singe in the direction of arrow 58. Since the medium can only slowly flow into the interior 48 through the metering bore 47, it takes a certain time until the diaphragm 37 is inside the pig. 2 has reached the position shown. During this time, the medium flowing through the inlet connection 5 flows continuously through the flow openings 17 and the flow channels 42 in the part 44 of the delay chamber 9 ₃ to from here in the direction of the arrows 56 through the shut-off device 20 into the outflow connection 6 and thus also to the To arrive at the consumer point.

Since this process of lowering the middle part 57 of the control diaphragm 37 against the drag plate 21 of the shut-off element 2U and thus also the Durohfluss amount passing through the delaying chamber 9 in the meantime from the respective stroke volume of the diaphragm 37 and the size of the DosioKbohnasg depends, the size of this Doeierbohrong is 47 ianses

βο BU select that the flow length necessary for the consumer is ready duroh the safety device flow before the middle part 57 of the membrane 37 his In dtr fig. 2 has reached the inclined position.

Is the desired flow rate through the safety device hindurohgeetröat and then the consumer valve located behind the Ausflußstutsen 6 is closed, so builds Eioh «unäohst in the consumer line upstream of this valve as well as the outflow s do sen 6 a new pressure, by its action the valve cone 31 is back in its in the Tig. 1 rest position shown is backprinted and The valve plate 18 also rests against the partition 7 again with its band 19. As a result of between the antechamber 8 and of the interior 4-8 taking place via the metering bore 47 Pressure compensation is achieved through the effect of the internal stress of the membrane 50 now also its middle part 53 again from the 8 return port 49 and thus provides the connection between the rope swine 43 of the delay chamber 9 and the interior free again

Likewise, the membrane 37 also reverses as a result of its signal tension again in your in the fig. 1 inclined rest position "back, with the medium from the interior 48 into the delay chamber" is uagepuapt. As soon as the control membrane 37 has returned to its rest position, the safety device is again fully operational to allow the specified maximum removal »tightness.

If the consumer valve mentioned above does not close in time, it is only incomplete, or there is some other leak present and if the pressure equalization described above does not take place, the Heebranalttelteil 57 leads the full way a and will be up to its in the flg. 2 inclined position

pressed, in which the inlet cross-section determined by the king gap 59 " to the shut-off device 20 is greatly reduced. This again has in the outflow nozzle 6 opposite the neighboring one Part 44 of the delay chamber 9 results in an additional pressure drop, which leads to a further shift in the Support plate 21 and the two valve cones 28 and 31 leads in the direction of arrow 55. The central part of the membrane runs here 57 behind the support plate 21 until the valve cone 28 lowers onto its uitz 29, like this one is shown in Fig. 3, so that the valve 20 is now completely closed and a further inflow of the is suppressed in the delay chamber 9 medium to the consumer point. The shut-off device 20 has thus fulfilled the task assigned to him and taken his locked position. As a result of what has already been described above Both the valve plate 18 and the diaphragm 50 and finally the control diaphragm return pressure equalization in their rest positions shown in FIGS. 1 and 3 back.

Of particular importance is the measure according to the invention that the smock part 57 of the membrane 37 of the support plate 21 approaches, but does not settle on the surface of the support plate 21 in a sealing manner. Has been with this process, the support plate 21 is lowered so that the zv / isehen the valve cone 28 and its seat 29 is located The flow gap is only very narrow this narrow gap even with only very low flow rates iamer still such a large pressure drop that the valve cone 20 and with it the support plate 21 as well the other valve cone 31 suddenly assumes the blocking position shown in FIG. 3. This quick closing movement However, the central part 57 of the membrane 37 cannot follow, so that between the interior space adjacent to the valve seat 29 60 and the confinement chamber 9 as well as the interior

room 4ϋ pressure equalization takes place, which is an automatic 3 Mcks division of the diaphragm 37 into its rest position has. The shut-off device 20, on the other hand, should take this as long as this remain closed until the damage incurred is determined and has been eliminated. This ensures that the security device according to the invention also to only very much responds to low excess flow rates.

Once the damage incurred by the consumer or in consumer care has been eliminated, the shut-off device ZO is reset in the manner specified below. First of all, a shut-off valve upstream of the safety device is closed and the consumer line is detached from the outflow nozzle 6; the outer valve cone is now accessible and, together with the other valve cone, can be opened 2% by hand by pressing against the direction of arrow 55 in the pig . 2 flow position shown are shifted. Since the shut-off device 20 is now open again, there is between the waste pipe connection 6 and the delay caramel? 9, a pressure equalization takes place, so that the intrinsic balance of the support element 24 can now also become effective, and the support plate together with the two valve cones 20 and 31 in dia in FIG. 1b'ig. 1 presses the position shown. The device is then ready for operation again, the consumer line is reconnected to the outflow outlet 6 and the upstream shut-off valve is opened again.
