Valve device

摘要

A valve arrangement having a valve, in particular, a disk valve, is provided which has a first housing with several connections for a fluid or a gaseous medium, and with a drive unit, which has a second housing with a drive mechanism arranged therein. The housings are at least essentially spaced apart from one another. The valve has a control shaft and the drive unit and a drive shaft that is operatively connected to the drive mechanism and operatively connected or operatively connectable to the control shaft by means of a coupling device. The coupling device is arranged between the first and the second housing.

1. A valve arrangement comprising:
a valve comprising a first housing with a plurality of connections for a fluid or gaseous medium and a control shaft, and a drive unit comprising:
a second housing with a drive mechanism,a drive shaft that is operatively connected to the drive mechanism and operatively connected or operatively connectable to the control shaft by means of a coupling device, the coupling device being arranged between the first housing and the second housing, anda splash guard allocated to the coupling device, wherein the splash guard has at least one first protective panel circumferentially surrounding the coupling device and at least one second protective panel circumferentially surrounding the coupling device, wherein the at least one second protective panel has a larger or smaller diameter than the at least one first protective panel in order to form a labyrinth seal for the coupling device together with the first protective panel, wherein the at least one first protective panel is configured in one piece with the first housing, and the at least one second protective panel is configured in one piece with the second housing, and wherein an axial distance is provided between free front sides of the at least one first protective panel and the at least one second protective panel and respective opposite housings, wherein the first housing and the second housing are spaced apart from one another to form a thermally insulating air gap between them, and wherein the first housing and/or the second housing comprises at least one spacer which is configured as a screw dome.
