Definitions

  • the present invention relates to a connection line for a tapping point, which has a pipe interrupter to avoid backflow and which has a regulating valve to limit the flow rate.
  • an adjustable throttle valve is known with a non-return valve effective in a flow direction.
  • the fluid can flow through the device in both directions, at least when the regulating valve is in a certain position.
  • the regulating valve With the regulating valve, the flow rate through the throttle valve in the flow direction of the backflow preventer can be partially regulated here.
  • the throttle valve works like a backflow preventer with an associated bypass line.
  • the regulator is unable to adequately control the flow of the medium through the backflow preventer.
  • the backflow preventer of the US-PS does not meet the requirements of DIN 1988 and DIN 3266 mentioned above.
  • Backflow preventer and regulating valve are arranged in a housing in the form of a corner valve in such a way that a complicated device with a large space requirement arises.
  • fittings are required which, through their structural design, enable the requirements for a pleasant and space-saving construction.
  • the object of the present invention is to provide a connection line for a tapping point with a pipe interrupter and a regulating valve in such a way that they form a structural unit and thereby result in a simple and space-saving construction.
  • the regulating valve is connected upstream of the "pipe interrupter in such a way that the regulating valve and the pipe interrupter form a unit, the housings of the regulating valve and the pipe interrupter having essentially the same diameter, the pipe interrupter on the inflow side receiving the regulating valve in such a way that the regulating valve holds the separating element of the pipe interrupter in contact with the pipe interrupter and a seal is provided between the front end of the regulating valve and an end face of the pipe interrupter by eliminating the connecting lines between the regulating valve and the pipe interrupter and the direct connection in series of these two elements
  • the new device is simple and space-saving, so that it can be used even with limited space.
  • the diameter of the inflow side of a pipe interrupter is larger than the diameter on its outflow side.
  • the regulating valve is connected upstream of the pipe interrupter, since the inevitable jump in diameter which is thus inevitable can then be avoided at the transition from regulating valve to pipe interrupter.
  • the diameter of the regulating valve is advantageously a maximum of three times the diameter of the connecting line.
  • the diameter of its housing on its inflow side is substantially larger than the diameter of the connecting line in which the pipe interrupter is arranged.
  • the regulating valve itself is designed as a reducer between the connecting line and the pipe interrupter.
  • the pipe interrupter has an internal thread on the inflow side for receiving an external thread of the regulating valve.
  • the pipe interrupter has a support sleeve carrying a hose membrane and the regulating valve holds the support sleeve with a flange-like extension in contact with an annular shoulder of the pipe interrupter.
  • the regulating valve is designed as an integrated component of the pipe interrupter, so that the structural unit formed from the regulating valve and pipe interrupter is particularly space-saving.
  • an advantageous embodiment of the device according to the invention provides that between the front end of the regulating valve and an end face of the pipe interrupter is provided with an annular seal and the pipe interrupter and the regulating valve have cooperating stops. This prevents the ring seal between the regulating valve and the pipe interrupter from being squeezed too severely and can therefore no longer function properly.
  • the regulating valve advantageously has a cylindrical outer surface with two diametrically opposed parallel flat key surfaces. In this way, the control valve and pipe interrupter can be connected using standard tools.
  • the regulating valve For reasons of accessibility for tools and also for aesthetics, it is desirable for the regulating valve to assume a very specific angular position with respect to the line.
  • the unit formed from the regulating valve and pipe interrupter is connected to the connecting line by means of a crimp connection. In this way, after loosening the crimp connection, the unit can be rotated into any desired position and then secured in this position by tightening the crimp connection.
  • the device according to the invention can be used in connection with differently designed tapping points and apparatuses, e.g. in connection with automatic coffee machines or glass rinsing devices on bar tables etc.
  • the unit consisting of the regulating valve and pipe interrupter is connected to the hose by a shower. In this way, the inflow-side part of the connecting line is secured against sucking back dirty water even if the shower head remains in the dirty water and then a negative pressure is created in the connecting line on the inflow side.
  • the regulating valve can be designed differently. However, for reasons of space saving and also aesthetics, it is desirable that the regulating valve have no protruding parts. In order to achieve this, it is preferably provided that the regulating valve has a rotary slide whose axis of rotation extends transversely to the flow direction.
  • the housing for receiving the drive spindle of a valve cone is required for the adjusting elements of a rotary slide valve, so that there is no need for a handle which projects radially outward beyond the regulating valve housing.
  • the rotary slide valve has a tool engagement surface accessible from outside the housing.
  • Such an attack surface need not protrude from the housing at all or only slightly, since the tool engagement surfaces can also be recessed in the form of a slot or a differently shaped hollow profile. To protect the tool engagement surface, it can be covered by a removable cap.
  • the rotary slide valve is designed as a cylinder bolt which has an expanding groove on its circumferential surface in the region of a flow hole connecting the inlet bore in the inlet connection with the outlet hole in the outlet connection. In the flow position, this groove connects the inflow hole to the outflow hole, the flow rate depending on the smallest cross section of the groove in the area of the flow hole. It is expediently provided that the groove widens both in width and in depth.
  • the two ends of the groove are separated from one another by a grooveless peripheral surface of the rotary slide valve, this peripheral surface being longer in the peripheral direction than the diameter of the flow bore controlled by the rotary slide valve .
  • the housing of the regulating valve according to the invention is closed on its side facing away from the tool engagement surface of the rotary slide valve, while an annular seal is provided between the widening groove and the end of the rotary slide valve with the tool engagement surface between the housing and the rotary valve valve. If the housing is closed on its side facing away from the tool engagement surface, an annular seal is sufficient for sealing. This is preferably arranged in an annular groove of the rotary valve.
  • the rotary valve can be secured axially in various ways, for example by the friction between the ring seal and the rotary valve.
  • two stops securing the rotary slide in the axial direction are provided, these two stops advantageously being formed by an annular groove provided in the rotary slide between the ring seal and the tool engagement surface, into which a pin guided in the housing engages.
  • the annular groove extends only over a partial area of the circumference of the rotary slide valve and, together with the pin, defines the adjustment range of the rotary slide valve in the regulating valve.
  • the device according to the invention enables a maximum flow to be determined independently of a shut-off device upstream of the pipe interrupter and is in particular re suitable for sanitary facilities because it is compact in structure and aesthetically pleasing in appearance. In addition, it can be easily installed in connecting lines.
  • FIG. 1 shows a connecting line, which consists of an elbow 4 and a hose 40, at the free end of a shower head, not shown, is attached.
  • a connecting line formed from elbow piece 4 and hose 40, a regulating valve 1 and a pipe interrupter 2 are arranged directly one behind the other.
  • the connecting line formed from elbow piece 4 and hose 40 is preceded by a shut-off valve 3.
  • a shut-off valve 3 With this, the inflow to the shower head, not shown, can be adjusted.
  • the shut-off valve 3 is often actuated only by feeling, and an uncontrolled splashing of water cannot be avoided. This is remedied by the regulating valve 1 upstream of the pipe interrupter 2, since the maximum flow rate can be set with this.
  • This flow rate is set independently of the flow rate released by the shut-off valve 3, so that an excessively large flow rate is reliably avoided even when the shut-off valve 3 is fully turned on.
  • the unit consisting of regulating valve 1 and pipe interrupter 2 can easily be retrofitted between shut-off valve 3 and hose 4, even by laypersons.
  • the components of this unit, namely the regulating valve 1 and the pipe interrupter 2 have essentially the same diameter D.
  • the regulating valve 1 and the pipe interrupter 2 visually merge and form a unit for the viewer. Due to this design, this unit is not only compact, but also pleasing in appearance, making it particularly suitable for sanitary facilities such as Suitable for showers.
  • the described device can also be used in connection with a shower connected to a bathtub mixer (not shown).
  • the unit formed by regulating valve 1 and pipe interrupter 2 is arranged directly on the underside of the bathtub mixer, so that this unit is located at the beginning of the connecting line formed by the hose.
  • the application is not limited to shower connections, but can also be used in connection with other tapping points.
  • a device consisting of a regulating valve and a pipe interrupter is also particularly advantageous in connection with glass rinsing devices of bar tables or also in connection with coffee machines. Again, it is excluded with certainty that contaminated water can be sucked back into the drinking water pipe. In both cases, this device should also be designed to be space-saving and aesthetically pleasing, since the water is supplied to the tapping point via plaster, with the space conditions generally also being very limited.
  • FIG. 2 A part of such a connecting line is shown in Fig. 2.
  • the connecting line consists of two pipe sections 5 and 50 and has in the flow direction P first a regulating valve 1 and then a pipe interrupter 2.
  • the pipe interrupter 2 has a housing 20 with an inlet connection 200 and an outlet connection 201.
  • the housing 20 has a cylindrical interior 202, in which an exchangeable insert 21 is mounted.
  • This insert 21 has an inlet connector 210, the interior of which is in constant communication with the inlet connector 200 of the housing 10.
  • the inlet connector 210 of the insert 21 merges into a support sleeve 216, which is closed at its end facing away from the inlet connector 210 by a radial wall 211.
  • the support sleeve 216 has radial inflow openings 212 in its peripheral wall at its end facing the inflow nozzle 210.
  • the inflow nozzle 210 has a flange-like extension 213.
  • a slot cage 214 which ends on the inflow side in a clamping ring 215, a hose membrane 22 is clamped with its inflow-side clamping end 220 between the clamping ring 215 and the flange-like extension 213 of the inflow nozzle 210, which at least with its outflow side End rests on the outer circumference of the support sleeve 216.
  • the clamping ring carries annularly distributed webs 217, between which slots, not shown, are formed. These webs are supported in the radial wall by the peripheral wall of the housing 20, which have openings 218 in the length region of the webs 217.
  • the housing 20 has in the length region with the openings 218 opposite the inflow nozzle 200 reduced diameter and has a circumferential groove 219 in this length range on the inflow side.
  • This circumferential groove 219 serves to receive an annular web 230 of a bell 23 which surrounds the entire length of the housing 20 with the openings 218 at a radial distance and ends on its side facing away from the annular web 230 at a distance from the housing peripheral wall, so that the interior 202 of the housing 20 is in constant communication with the atmosphere via the slots between the webs 217 and the openings 218.
  • the housing On the outlet side, the housing has the outlet connection 201 already mentioned, on the inner wall of which the hose membrane 22 can be brought into contact when the medium flows through the pipe interrupter 2.
  • the medium leaves the inlet connector 210 through the inlet openings 212 and flows between the support sleeve 216 and the hose membrane 22 to the outlet connector 201 of the housing 20.
  • the drainage pipe 201 has an external thread 203, onto which a union nut 24 can be screwed.
  • a conical ring 240, an intermediate washer 241 and an annular seal 242 are provided on the pipe section 50 in a conventional manner, which produce a sealing connection between the pipe section 50 and the pipe interrupter 2 when the union nut 24 is screwed onto the drain connection 201.
  • the regulating valve 1 has a housing 10 with an inlet connection 100 and an outlet connection 101, the bores of which are connected to one another by a through-bore 102.
  • a further bore 103 extends across the through-bore 102 and is closed at one end.
  • this bore 103 there is a rotary valve 11, the axis of rotation 110 of which thus extends transversely to the flow direction P.
  • the inlet connection 100 of the regulating valve 1 has an external thread 104 onto which a union nut 14 can be screwed, a conical ring 140, an intermediate disk 141 and an annular seal 142 being provided here for sealing.
  • the drain connector 101 of the regulating valve 1 has an external thread 105 with which the housing 10 can be screwed into the inlet connector 200 of the housing 20 which has an internal thread 204.
  • an annular seal 12 is provided between the front end of the drain connector 101 of the regulating valve 1 and the extension 213 of the insert 21.
  • the housing 10 of the regulating valve 1 forms a stop 106 which cooperates with the inflow nozzle 200 of the pipe interrupter 2 as a counter-stop.
  • the regulating valve 1 and the pipe interrupter 2 have essentially the same outer diameters D, this outer diameter D of the regulating valve 2 should at most be three times the diameter d of the connecting line. Both in terms of function and in terms of visual impression, these two elements can therefore be arranged in any order to one another.
  • the pipe interrupter 2 Because of the insert 21, which must be inserted into the pipe interrupter 2, the pipe interrupter 2 has an outside diameter which cannot fall below a certain level and is substantially larger than the diameter d of the connecting line (pipe sections 5, 50 or elbow piece 4 and / or hose 40) is. Such a large diameter is not required for the regulating valve 1, which is why, in the embodiment of the pipe interrupter 2 shown in FIGS. 1 and 2, on the inflow side has the mentioned internal thread 204 for receiving the drain connector 101 of the regulating valve 1 provided with an external thread 105.
  • the regulating valve 2 can be designed as a clamping element for the support sleeve 216, which holds the support sleeve 216 with its flange-like extension 213 in contact with an annular shoulder (clamping ring 215) of the pipe interrupter 2 (FIG. 2). Separate elements are therefore unnecessary for this purpose if the regulating valve 1 is connected upstream of the pipe interrupter 2.
  • the inflow nozzle 200 of the pipe interrupter 2 cannot fall below a certain value.
  • a reducer is therefore required to connect the pipe interrupter 2 to the pipe section 5 arranged in front of it in the flow direction P.
  • the regulating valve 1 has a cylindrical outer surface. So that the regulating valve 1 can nevertheless be connected to the pipe interrupter 2 in a simple manner and without the risk of damage, two key surfaces 15 (FIG. 1) are provided diametrically opposite one another in this cylindrical outer surface.
  • the pipe interrupter is not provided with an otherwise usual hexagon profile, but also has two key surfaces 25 in its round outer surface valve 1 and the pipe interrupter 2 are screwed together in a simple manner with the aid of conventional tools.
  • the aim is to orient the axis of rotation 110 of the rotary valve 11 in a certain way. Since the regulating valve 1 only has the task of determining the maximum amount that can flow through the connecting line, the rotary valve 11 is usually rotated after the setting of the maximum flow rate in the connecting line so that it is no longer visible and not or only poorly is accessible to prevent abuse.
  • the unit consisting of regulating valve 1 and pipe interrupter 2 is connected to the adjacent pipe sections 5 and 50 by means of crimp connections (24, 240, 241, 242 or 14, 140, 141, 142) for this purpose on the inflow and outflow side .
  • crimp connections 24, 240, 241, 242 or 14, 140, 141, 142
  • the connecting line 4, 40, 5, 50 and the regulating valve 1 and the pipe interrupter 2 can be modified in the context of the present invention in a variety of ways by exchanging Merkma len for equivalents or other combinations. So it is possible, for example, that the rotary valve 11 protrudes slightly beyond the outer circumference of the housing 10 of the regulating valve 1 and is provided with a cord for actuation.
  • the actuating device for the rotary slide valve 11 becomes even more compact and inconspicuous if it has a tool engagement surface 111 accessible from outside the housing 10.
  • a tool engagement surface 111 accessible from outside the housing 10.
  • the rotary slide valve projects slightly beyond the peripheral surface of the housing 10 in the exemplary embodiment shown, but this is not absolutely necessary, since the tool can also cooperate differently with the tool engagement surface 111.
  • a web or a polygonal profile (e.g. triangular, square or hexagonal profile) can also be provided as the tool engagement surface 111, this optionally projecting over the end face of the rotary slide valve 11 or can also be designed as a hollow profile.
  • the housing 10 shown has an annular groove 107, in which a cap 16 is removably mounted by a snap connection or the like, so that the tool engagement surface 111 is covered to the outside when the cap 16 is inserted.
  • the rotary valve 11 can in principle also be designed in various ways, for example as a bore, which can be brought into alignment with the bore 102 by turning the rotary valve 11 or adjusted transversely thereto. This allows the flow to be regulated from zero to a maximum quantity.
  • the rotary slide valve 11 is designed as a cylinder bolt which has a widening groove 112 in the area of the flow bore 102 on its circumferential surface. Depending on the available space, it may be sufficient if the groove 112 only widens in width. In the tight spaces shown, however, it is provided that the groove 112 widens both in width and in depth. This allows precise control even in very tight spaces.
  • the rotary valve 11 can be produced in a simple manner as a molded part made of metal or plastic or the like.
  • a grooveless peripheral surface 113 is provided between the two ends of the groove 112, which separates the two ends of the groove 112 from one another.
  • This circumferential surface 113 is longer in the circumferential direction of the rotary slide valve 11 than the diameter of the flow bore 102. This makes it possible to completely close off the flow through the flow bore 102 (see FIG. 3), so that e.g. when replacing the hose membrane 22 in the pipe interrupter 2, the regulating valve 1 can also serve as an auxiliary shut-off valve.
  • Fig. 4 shows the rotary valve 11 in its other extreme position, in which it enables maximum flow through the regulating valve 2.
  • the rotary valve 11 has a circumferential groove 114, in which an annular seal 115 is mounted.
  • This ring seal 115 seals the inside of the housing 10 from the outside. Since this ring seal 115 is located between the outer wall of the housing 10 and the flow bore 102, the ring seal 115 does not have to be pushed over this flow bore 102 when the rotary slide valve 11 is inserted into the housing 10, so that it is inserted into the housing 10 when the rotary slide valve 11 is inserted is also not subject to a particularly large load, as would be the case if this ring seal 115 had to pass through the flow bore 102 when the rotary slide valve 11 was inserted.
  • the bore 103 in the exemplary embodiment shown is closed on the side facing away from the tool engagement surface 111, although it is in principle possible to provide ring seals for the rotary valve 11 on both sides of the bore 102. In this way, a particularly careful deburring of the through-bore 102 can be dispensed with.
  • any two stops can be provided in a suitable manner, which axially secure the rotary slide valve 11 in both directions.
  • the rotary valve 11 is axially secured with the aid of a pin (FIG. 5) which is inserted into the housing 10 in such a way that it is guided tangentially to the rotary valve 11 and engages with an annular groove 116 provided in the rotary valve 11 located.
  • the annular groove 116 is provided between the ring seal 115 and the end of the rotary valve 11 with the tool engagement surface 111.
  • This pin 13 thus, together with the annular groove 116, fulfills the task of two stops working in opposite directions with the rotary valve 11.
  • the guide bore for the pin 13 is outside the flow area of the regulating valve 1, it can be deburred in the area of the bore 103 such that the ring seal 115 can be pushed over this guide bore without risk of damage.
  • the annular groove 116 extends only over part of the circumference of the rotary valve 11, so that the ends of the annular groove 116 form a rotary stop for the pin 13 and thus define the adjustment range of the rotary valve 11.
