| 摘要 |
The invention relates to a sanitary insertion unit (1), comprising an insertion housing (2), in which at least one closing valve (3) having an annular channel (4) is provided, in which annular channel (4) an annular valve body (5) composed of elastic material is arranged, which valve body deforms under the pressure of the incident fluid in such a way that the valve body (5) tightly closes the annular channel (4). The insertion unit according to the invention is characterized in that the annular channel (4) of the at least one closing valve (3) has a profile (6) on an inner and/or outer channel wall. By means of said profile (6), better controllability of the closing valve (3) during the closing process of the valve body of the closing valve can be achieved and disturbing noises and vibrations are effectively avoided. |
