Definitions

  • the present invention relates to a regulating and shut-off valve according to the preamble of claim 1, as for example from the DE-U-200 01 883 is known.
  • Such a fitting has a valve housing in which a valve plug is displaceably guided and sealingly engageable with a valve seat formed on the valve housing.
  • the regulating and shut-off valve has a valve outlet housing, into which a valve top is screwed with a rotatably arranged in this and connected to a rotary handle spindle.
  • an intermediate tube is provided whose length is dimensioned such that the valve housing in the interior of a building and the valve outlet housing, the outer wall of the building can be arranged outstanding.
  • the intermediate tube surrounds an intermediate spindle, which engages with the spindle, so that an axial displacement of the intermediate spindle takes place by rotation on the rotary handle, which is transmitted to the valve cone, which is in operative connection with the intermediate spindle.
  • the previously known regulating and shut-off valve on a vent valve which has a valve with an open poppet occluding a venting sealing element which releases the vent opening with the valve plug closed.
  • a venting valve body provided under spring preload on the valve outlet housing is provided. This is spring biased so that when acting in the valve outlet housing internal pressure, which also acts on the vent valve body, the vent valve is closed, whereas with shut off valve and running water from the valve, the vent valve opens at low internal pressure to one between the intermediate spindle and vent the intermediate space formed between the upper valve part and the valve cone when the shut-off valve is shut off, ie, the valve cone sealingly abuts against the valve seat.
  • the control of the vent valve is not always reliable. Thus, it may happen that a hose is connected to an outlet of the valve outlet housing, which can be closed at the end, before the regulating and shut-off valve closed becomes. In this case, the internal water pressure in the valve outlet housing is not degraded, so that the vent valve is not actuated and a ventilation of the valve can not be performed thereafter. In frost, the valve can be blown up.
  • the US 4,475,570 discloses an outlet fitting with forced ventilation.
  • the previously known outlet fitting has a valve seat housing in which a valve plug is displaceably guided and can be applied sealingly against a valve seat formed on the valve seat housing. Furthermore, a valve outlet housing is provided. Between this valve outlet housing and the valve seat housing is an intermediate tube. Furthermore, the previously known outlet fitting to a valve. This is located in the outlet housing and regulates the flow passage to a hose nozzle. In the usual water extraction, this valve is deformed by the water pressure so that water flow is possible.
  • the threaded engagement for mediating an axial movement by the rotational movement of the spindle takes place in the outlet housing after the US 4,475,570 via the valve seat housing, which is bridged for the flow of water by a recessed inside a threaded sleeve flow passage.
  • the design according to this prior art requires a very accurate dimensional coordination between the actuator body and the position of the pin with respect to a sealing contact with the valve seat.
  • the present invention is based on the problem, the regulating and Absperrara-matur of the type mentioned in such a way that a reliable venting of the valve can take place independently of the internal pressure in the valve outlet housing.
  • the present invention is further based on the problem of improving the above-mentioned regulating and shut-off valve in terms of their durability.
  • the present invention provides a regulating and shut-off valve having the features of claim 1.
  • the regulating and shut-off valve according to claim 1 has an actuating body, which cooperates with the spindle and is held longitudinally displaceable in the valve upper part.
  • the adjusting body is rotationally held in the valve bonnet.
  • the actuator is inventively designed so that it is closed when the valve cone, i. can be moved longitudinally displaceable with a closed valve from a first position to a second position and in this case acts on the sealing element of the venting valve, that this closes the vent in the first position of the actuating body and releases it in a second position of the actuating body.
  • the actuator according to the present invention is rotationally held relative to the spindle, but cooperates with this, for example, such that the displacement movement of the actuator is at least partially coupled to a sliding movement of the spindle and / or the displacement movement of the actuator in the valve outlet housing of the rotation of the Spindle is influenced, in particular directly due to the pitch of the spindle in the longitudinal direction thereof is adjusted. This adjustment takes place in particular when the valve is closed.
  • the actuator can be adjusted from the first to the second position. In the first position of the actuating body acts on the sealing element such that it closes the vent opening, whereas the sealing element in the second position of the actuating body releases the vent opening.
  • FIG. 1 are the essential components of an embodiment of a designed as a water tap regulating and shut-off valve shown comprising a valve housing 2, a valve outlet housing 4 and an interposed, both housing 2, 4 rotationally interconnecting intermediate tube 6.
  • a valve seat 21 is formed, to which a valve plug 22 can be sealingly brought into abutment.
  • the system is carried out in the manner of a straight seat valve.
  • a mounting flange 23 is provided, which is preferably mounted on the inside of a housing wall.
  • the valve housing 2 also has an inlet connection 24 for connection to the pipeline system of the building.
  • the intermediate tube 6 On the other side of the valve housing 2, the intermediate tube 6 is mounted rotationally fixed, the length of which is such that a sleeve 61 rests against the outer wall of a finished building wall.
  • the intermediate tube 6 can be filled over its entire length with an iso be coated 62 lation.
  • the insulation 62 extends up to an annular contact surface of the sleeve 61 against the building wall.
  • the intermediate tube 6 surrounds an intermediate spindle 63, which is connected to a connecting sleeve 64 which displaceably guides the valve cone 22 and forms part of a backstop which presses a valve body 22 holding the valve cone 22 against the valve seat 21 under bias of a spring 26 with the shut-off valve closed.
  • the intermediate spindle 63 is supported via sliding rings 65 on the inner circumferential surface of the valve housing 2.

  • the intermediate spindle receptacle 43b has a larger inner diameter than the guide sleeve section 43a, and between the two sections 43a, 43b of the adjusting sleeve 43 an adjusting sleeve shoulder 43e is provided which forms an annular contact surface 43d for the spindle shoulder 41b.
  • the outer peripheral surface of the guide sleeve portion 43 a of the adjusting sleeve 43 is sealingly on sealing rings 42 a, which are received in the valve upper part 42.
  • the intermediate spindle 63 is rotationally fixed, but held axially displaceable in the intermediate spindle receptacle 43 b; the adjusting sleeve 43 in turn is axially displaceable with its guide sleeve portion 43a, but guided rotationally in the valve upper part 42.
  • a compression spring 44 which is held between the guide sleeve portion 43 a and the rosgriff workedem end of the valve top 42 under spring tension, which rotatably on the handle side forms a radially inwardly on the guide portion 41 e towards tapered contact ring 42 b.
  • the compression spring 44 is applied on one side of this plant rim 42b.
  • the opposite side of the contact ring 42b forms the counter surface to the abutment surface 41d of the spindle 41 formed on the snap ring 41c.
  • the valve outlet housing 4 has, on its underside, a hose nozzle 46 screwed on with the interposition of a pipe aerator 45, which axially extends an outlet channel 47, which extends substantially perpendicularly to the longitudinal axis of the intermediate spindle 43 or the spindle 41.
  • the outlet channel 47 is continued in the form of a vent hole in which a vent opening 48 releasing vent valve 49 is arranged.
  • This vent valve 49 has a vent valve body 49a, the biasing of a vent spring 49b against a sealing surface of a vent valve insert 49c with the interposition of a sealing element 49d the vent 48 abuts laying.
  • the vent valve insert 49c is screwed into the valve outlet housing 4 and covered by a cap 50 which is also screwed onto the valve outlet housing 4.
  • the vent valve body 49a has at its spindle end a front rounded guide cone 49e, which abuts permanently due to the spring bias 49b against the outer peripheral surface of the intermediate spindle receptacle 43b of the adjusting sleeve 43.
  • the latter has a curve profile 43f which comprises a plateau extending substantially in the axial direction and two ramps which extend obliquely therefrom and connect the plateau to the outer peripheral surface of the intermediate spindle receptacle 43b and whose dimensioning results from the following description.
  • FIG. 2 is the embodiment of FIGS. 1 to 3 shown with shut off valve.
  • the valve cone 22 is sealingly against the valve seat 21.
  • the intermediate spindle 63 has been displaced maximally out of the intermediate spindle receptacle 43b by rotation with respect to the spindle.
  • the guide cone 49e of the vent body 49a abuts on the outer circumferential surface of the actuator sleeve 43a at the foot of the ramp and releases the vent passage 48.
  • the valve is vented.
  • the adjusting sleeve 43 is in the second position.
  • the rotation on the handle 55 initially leads to a positional shift of the adjusting sleeve 43 relative to the upper valve part 42 and relative to the intermediate spindle 63.
  • this movement of the adjusting sleeve 43 is transmitted to the spindle 41.
  • the guide cone 49e travels over the curve profile 43f, ie via the ramp to the plateau, whereby the sealing element 49d is placed against the force of the spring 49b against the sealing surface formed on the vent valve body 49a. The vent valve 49 is thus closed.
  • valve 3 shown first position of the adjusting sleeve 43, wherein the valve body 49a closes the vent opening 48, in its in FIG. 2 shown second position in which due to the position of the adjusting sleeve 43, the vent valve is open. Due to the spring force of the compression spring 44 in this case the regulating and shut-off valve remains closed, ie the valve cone 22 remains sealingly applied to the valve seat 21.
  • vent valve 49 Due to the cam control between the adjusting sleeve 43 and the vent valve 49, the vent valve 49 is forcibly opened after the regulating and shut-off valve has been closed.
  • the venting valve 49 is integrally received in the valve outlet housing 4.
