Abstract

Device for actuating a diaphragm valve, comprising a housing, wherein the housing is preferably formed of a top and bottom part, and further comprising an electric motor, a base board for the fastening of electrical components, a gear unit for actuating the diaphragm valve or the spindle nut of the diaphragm valve, and a position indicator for indicating the degree of opening of the diaphragm valve, wherein the position indicator is driven via the gear unit.

First claim

1 . A device for actuating a diaphragm valve comprising: a housing, wherein the housing is preferably formed of a top and bottom part, and further includes an electric motor, a base board for the fastening of electrical components, a gear unit for actuating the diaphragm valve or the spindle nut of the diaphragm valve, and a position indicator for indicating the degree of opening of the diaphragm valve, characterized in that the position indicator is driven via the gear unit.

2 . The device according to claim 1 , wherein the device is operated by means of electric current or electrically.

3 . The device according to claim 1 , wherein the position indicator indicates, by a rotational movement or rotary movement, the degree of opening of the diaphragm valve.

4 . The device according to claim 1 , wherein the device has an initiator.

5 . The device according to claim 4 , wherein the initiator is arranged on the position indicator.

6 . The device according to claim 4 , wherein the initiator is configured as a rotary encoder.

7 . The device according to claim 1 , wherein the several revolutions of the spindle nut which are required for the complete opening and/or closing of the diaphragm valve are geared down into maximally one revolution of the position indicator for indicating the degree of opening of the diaphragm valve.

8 . The device according to claim 1 , wherein the gear unit has, or adjoining the gear unit there is, at least one further or additional gear step for driving of the position indicator and corresponding gearing down of the rotation speed.

9 . The device according to claim 1 , wherein the position indicator has a position indicator shaft and a display button.

10 . The device according to claim 1 , wherein the position indicator or the position indicator shaft is coaxially connected to the gearwheel, wherein the gearwheel is positively and coaxially connected to the spindle nut of the diaphragm valve, preferably by means of an adapter.

11 . The device according to claim 9 , wherein on the position indicator shaft is arranged a gearwheel.

12 . The device according to claim 1 , wherein the position indicator is arranged fully in the housing.

13 . The device according to claim 1 , wherein the housing has a transparent region.

14 . The device according to claim 1 , wherein the device has an intermediate element, wherein the intermediate element serves to fasten the device to the diaphragm valve.

15 . The device according to claim 1 , wherein the device has an adapter, wherein the adapter couples the gear unit to the diaphragm valve or the gearwheel to the spindle nut of the diaphragm valve.
