Shut-off and reversing valve

Abstract

A disc-type control valve with total volume control and distribution functions for distributing incoming water to one of several outlets (8, 3). In order that a respective movable control disk can be actuated individually to cooperate with the connected fixed distribution disk (7) for the two control devices (9, 15), the two movable control disks are aligned with each other. The pressure supports can be individually adjusted and adjusted. Two actuation parts (14, 19) are used for actuation, one of which is arranged as a sleeve around the other part.

Description

technical field

[0001] The invention relates to a valve in which the possibility of closing and dispensing of water to one of several dispensing outlets are combined. Background technique

[0002] Such valves are well known. Typically, there is a single actuator (or drive) with which the output and select water outlets can be actuated by the valve. Since most cleaning (or pumping) valves are made as ceramic disc valves, a problem arises in that the volume of the ceramic disc increases as the number of dispensing outlets increases. Consequently, due to the increased friction, the force required to actuate the valve increases. This applies in particular during the combined closing and dispensing activities performed in the same pair of control discs in order to reduce the overall height of the valve.

[0003] A valve with which several outlets can be closed and distributed is known (see patent document US6357476). Since the pivoting control dial of one control device inter...
