Definitions
- the invention relates to a valve upper part for sanitary fittings, with a head piece which is axially penetrated by a control spindle, via which a valve body arranged in the head piece can be actuated, and which is connected to an operating device comprising a handle, wherein the handle (1) is displaceable relative to the head piece (83) coaxially to the control spindle (81).
- Valve bonnets are used to control the outlet of media from fittings.
- the valve bonnet is screwed into the fitting body using its head piece.
- Valve bonnets of the aforementioned type are known in a wide variety of designs.
- EP 3 062 002 A1 discloses a valve bonnet which has a head piece through which a spindle passes. The spindle is positively connected in the head piece to a control disc which rests against a stationary inlet disc. The water flow is controlled by rotating the control disc relative to the inlet disc.
- the end face protruding from the head piece is designed as an external polygon and is provided with a threaded blind hole on the inside for the positive attachment of a rotary handle.
- EP 2 522 887 A1 also discloses a valve upper part in which a valve body is provided to control the flow of a fluid.
- the valve body is linearly movable within the head piece via a spindle.
- a spindle is rotatably mounted in a head piece and connected via a thread to a valve body axially guided in the head piece in a rotationally secure manner. Rotation of the spindle thus causes an axial movement of the valve body within the head piece.
- valve head In the design of valves, there is an increasing demand for the valve head to be operated via pushbuttons or buttons. Electromagnetically operated valves are frequently used for this purpose.
- the disadvantage of these valve heads is that the electromagnetic contacts are The screwing or gluing of the valve body can be damaged, thereby impairing reliability. Furthermore, such valves require an additional power source. Furthermore, flow control is generally not possible with these valves.
- EP 3 366 959 A1 proposes a valve upper part in which the handle has a control cap with which it can be displaced along the head piece and via which a control piston can be actuated.
- a cam track with two locking positions is incorporated into the outer surface of the head piece, into which a guide pin arranged on the control cap engages.
- valve head shown above also known as a "push valve”
- push-to-operate operation e.g., switching the water outlet (shower/shower head) or retracting the valve handle when not in use
- rotary operation e.g., adjusting the water flow rate
- DE 20 2023 101 163 U1 proposes a valve upper part that allows both push-to-open and turn-to-open actuation.
- the handle is slid onto the spindle of the valve upper part and mounted on it for sliding movement. By axially pulling the handle, it can be moved into two different positions, in which it can be locked.
- excessive pulling on the handle poses the risk of inadvertently removing the handle from the spindle.
- the invention aims to remedy this situation.
- the invention is based on the object of providing a valve upper part in which an unintentional removal of the handle from the spindle is prevented. According to the invention, this The problem is solved by a valve upper part with the features of patent claim 1.
- the invention provides a valve upper part in which inadvertent removal of the handle from the spindle is prevented. Because the handle is connected to the spindle via an adapter piece that is slidably mounted in the handle, with the adapter piece being captively retained in the handle, inadvertent removal of the handle from the spindle is prevented.
- the adapter piece is provided with an external thread in some areas, and the handle is provided with an internal thread in some areas.
- the external thread of the adapter piece is screwed into the internal thread of the handle and then tightened, thereby forming the loss prevention device. This allows for easy installation of the loss prevention device during assembly.
- the handle has an internally circumferential internal thread ridge
- the adapter piece has an externally circumferential external thread ridge, at least in some areas.
- the external thread ridge is screwed into the internal thread ridge and subsequently over-tightened such that the external thread ridge is located behind the internal thread ridge when viewed in the direction of the handle.
- an adjusting sleeve is arranged in the handle, which has the circumferential thread ridge and in which the adapter piece is displaceably mounted.
- the handle is rotatable relative to the headpiece and is connected to the control spindle in a rotationally fixed manner at least in one axial position. This allows both push and turn actuation.
- the adapter piece has at least one locking means circumferentially at least in some areas, wherein inside the handle or the At least one locking groove is arranged in the adjusting sleeve, with which the at least one locking means can be locked in a defined position of the adapter piece in the handle or in the adjusting sleeve. This enables a defined axial positioning of the adjusting sleeve on the adapter piece.
- the at least one locking means is formed by one or more locking lugs.
- the locking means can also be formed by a circumferential elastic ring element, preferably an O-ring.
- two locking grooves are arranged axially spaced from one another, preferably radially, inside the handle or adjusting sleeve. This achieves two defined axial positions of the handle, enabling a defined first axial position for a rotationally fixed connection of the handle to the control spindle and a defined second axial position without a rotationally fixed connection of the handle to the control spindle.
- the handle or adjusting sleeve is provided with internal teeth that engage with external teeth of a driver connected to the control spindle, whereby the handle is guided axially displaceably along the driver. This allows a rotationally fixed connection to the control spindle to be achieved by longitudinally displacing the handle, if necessary.
- the handle can be fixed in at least two axial positions via a locking device.
- the locking device preferably comprises a control piston which is guided in a control cylinder and which has a control link into which an engagement part arranged on the control cylinder engages, which engagement part is preferably formed by a ball which is guided radially movable in the control cylinder, wherein a spring is arranged between the control cylinder and the control piston, which spring is pretensioned against the control cylinder.
- the control piston has the driver, in whose external toothing the internal toothing of the adjusting sleeve engages.
- the control cylinder preferably has an external thread onto which the adapter piece is screwed with its internal thread. This enables fine adjustment of the axial position of the handle on the spindle of a valve bonnet installed in a wall.
- rotating the handle causes a longitudinal adjustment of the adapter piece along the external thread of the control piston. Inaccuracies during the installation of a valve bonnet and the required cutting of the control spindle, which is usually carried out in this process, can thus be compensated for by adjusting the adapter piece.
- the present invention further relates to a sanitary fitting with a valve upper part according to patent claim 15.
- an “adjustment position” refers to the position of the handle in which the locking means of the adapter piece engages with the second, lower locking groove of the adjusting sleeve. In this position, adjustment is possible via the threaded engagement between the external thread of the control cylinder and the internal thread of the adapter piece. The internal teeth of the adjusting sleeve are disengaged from the external teeth of the control piston.
- the control cylinder 3 is moved back by the restoring force of the compression spring 59, whereby the balls are moved into the holding area 522 of the control link 52. In this position, the handle 1 is held by the balls. In this position, the handle 1 is completely retracted into the installation sleeve 7 in the retracted position, with the surfaces of the handle 1 and the collar 71 of the installation sleeve 7 lying on the same plane (see Figure 6).
