Embodiment Construction

[0033] Figures 1 to 6 Shown is a sectional view of the dispensing valve with a flow meter according to the invention in the same cut-away position in different adjustments and states, ie with the valve fully closed ( figure 1 ), with the valve fully open ( figure 2 ), in the case of a valve adjustment for a defined flow adjustment, a stop nut 6 without a corresponding adjustment ( image 3 ), a stop nut 6 with a corresponding adjustment ( Figure 4 ) and a stop nut 6 with a lock in the adjusted position ( Figure 5 ), and with the stop nut 6 locked in the adjusted position when the valve is fully closed ( Figure 6 )

[0034] All illustrations each show the valve in a non-flowing state, so that the display of the flow meter does not show a flow in all illustrations, which will then be discussed more precisely.

[0035] The distribution valves shown are arranged to regulate the flow through the hot water heating circuit and are passed from the outside to two opposed The...

Abstract

The invention relates to a distribution valve for use in the feed or return of a medium circuit, comprising a housing (1) that forms the feed or return conduit, a branch conduit (2) branching off thehousing (1), and an adjusting unit (3) for adjusting the flow rate through the branch conduit (2), said adjusting unit being separate from the housing (1) and being arranged on the housing (1) opposite the branch conduit (2) and extending through the housing wall. The adjusting unit (3) comprises an adjusting spindle (4) the axial position of which relative to a component (5) of the adjusting unit(3) connected to the housing (1) can be varied by rotation, thereby varying the flow rate. The valve is designed such that an axial movement of the adjusting spindle (4) relative to the component (5)towards the branch conduit (2) results in an increase in the flow rate through the branch conduit (2). The valve according to the invention further comprises adjustable stop means by means of which an axial movement of the adjusting spindle (4) relative to the component (5) towards the branch conduit (2) can be limited in a defined axial position when a first stop face (7) connected to the adjusting spindle (4) abuts a second stop face (8) connected to the housing (1), in order to limit the maximum adjustable flow rate through the branch conduit (2). The invention provides in a cost-effectivemanner distribution valves that are compact and have a simple design and the flow rate limitation of which, once adjusted to a certain value, remains the same even despite temporary shut-off or temporary reduction of the flow rate.

Description

technical field [0001] The invention relates to a dispensing valve according to the preambles of the independent claims, a distributor arrangement having such a dispensing valve and a regulating unit or a regulating and measuring unit for such a distributing valve. Background technique [0002] Distribution valves are used where one or more side pipes are to branch off from the main pipe. The dispensing valve is preferably used in combination with a flow meter where the flow of the medium through the pipeline system is to be adjusted to a defined value over a long period of time and should then be permanently and directly readable. Especially in the field of housekeeping, such distribution valves are increasingly used to regulate the flow of hot water through the individual hot water heating circuits. In this case, a plurality of distribution valves are preferably formed for a corresponding number of heating circuits in that a distributor beam (Verteilerbalken) serving as a...
