Sanitary insertion unit

Abstract

A sanitary insertion unit includes an insertion housing in which at least one closing valve having an annular channel is provided. An annular valve body composed of elastic material is arranged in the annular channel, the valve body deforms under the pressure of the incident fluid in such a way that the valve body tightly closes the annular channel. The annular channel of the closing valve has a profile on an inner and outer channel wall. Via the profile, better controllability of the closing valve during the closing process of the valve body of the closing valve can be achieved and disturbing noises and vibrations are effectively avoided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) FIGS. 1 to 5 illustrate a sanitary insert unit 1 having an insert housing 2 in which at least one closing valve 3 having an annular channel 4 is provided. Arranged in the annular channel 4 of the insert unit 1 is an annular valve body 5 made of resilient material, which deforms under the pressure of the inflowing fluid such that the valve body 5 tightly closes the annular channel 4.

(9) The insert unit 1 can be inserted into a sanitary supply line and in particular into a water pipe at a suitable point with its insert housing 2. The valve body 5 located in the annular channel 4 of the at least one closing valve 3 deforms under the pressure of the inflowing fluid such that the valve body 5 tightly closes the annular channel 4. In this case, the annular channel 4, provided for the valve body 5, of the at least one closing valve 3 has profiling 6 on an internal and/or external channel wall (I, O). In the exemplary embodiment illustrated in FIGS. 1 to 5, such profiling 6 is provided both on the internal (I) and on the external (O) channel wall.

(10) It is clear, from comparing FIGS. 1 to 5, that the profiling 6 is configured in an encircling manner on the channel walls (I, O). In this case, the profiling 6 provided on the channel walls (I, O) is formed from alternate indentations 7 and protuberances 8 oriented in the direction of throughflow. While each protuberance 8 in this case has a rounded and in particular approximately semicircular cross-sectional contour, each indentation 7 is configured as the region arranged between two protuberances 8 that immediately adjoin one another.

(11) It is clear from the plan view of the outflow side of the insert housing 2 in FIG. 5 that the external channel wall (O) is connected to the internal channel wall (I) of the at least one annular channel 4 via connecting webs 9 that are oriented approximately radially in this case, wherein the resilient valve body 5 of the at least one closing valve 3 bears on the connecting webs 9 arranged on the outflow side of the at least one annular channel 4.

(12) In an alternate embodiment as shown in FIG. 6, the insert unit 1 can also have at least two closing valves 3, 3 in its insert housing 2, which preferably have annular channels 4, 4 that are arranged concentrically with one another in the insert housing 2.

(13) As a result of the profiling 6 located on the channel walls (I, O) arranged on both sides of the annular channel 4, better controllability of the closing valve 3 during the closing operation is achievable and in the process, disruptive noise and vibrations are avoided. Since the profiling 6 is provided on the internal (I) and/or external (O) channel wall of the annular channel 4 of the at least one closing valve 3, and since constant speed profiles of the water flowing through cannot form around the annular channel circumference on account of the alternate indentations and protuberances 7, 8 of the profile 6, and since, instead, the formation of such a regular speed or pressure profile in the closing valve 3 of the insert unit according to the invention is disrupted, oscillation formation associated with undesired noise and vibrations is effectively avoided. It goes without saying that, in addition to the at least one closing valve 3, further closing valves and in addition to or instead of the latter also a backflow preventer, a flow rate regulator and/or a jet regulator can also be provided in the insert housing 2 of the insert unit 1. In this case, in a preferred embodiment, as shown in FIG. 6, according to the invention, the at least one closing valve 3, 3 is connected upstream of a jet regulator 10 and in particular a jet splitter 11 of the jet regulator 10 or is connected alongside the latter as a bypass.
