Abstract
Metering device in particular for metering an additive in the field of oil exploration with a metering element adjustable by an adjusting means. To improve such a metering device in that already with minimal movement of the adjusting means in a constructive simple way a particular amount of additive is added to raw material and also to quickly interrupt the metering, the metering element comprises a metering gap and a valve means arranged behind the metering gap downstream in fluids moving direction.
Claims26
Dosage feed device for the dosage feed of an additive fluid, the dosage feed device comprising:
- a dosing element, which can be adjusted by an adjustment device;
- the dosing element including a dosing gap and a valve device arranged following the dosing gap in a direction of fluid flow of the additive fluid, the valve device having an open and a closed position;
- the dosing gap being formed between inner and outer members movable relative to one another by the adjustment device;
- and
- the valve device being movable from the closed position to the open position without adjusting the dosing gap and one of the inner or outer members being movable from a flow position to an adjustment flow position adjusting flow through the dosing gap.
Dosage feed device for the dosage feed of an additive fluid, the dosage feed device comprising:
- a dosing element, which can be adjusted by an adjustment device, and
- the dosing element including a dosing gap and a valve device arranged following the dosing gap in direction of fluid flow of the additive fluid;
- wherein the dosing gap is formed between a dosing cone and counter element, whereby the dosing cone and counter element are movable relative to one another;
- and
- wherein the dosing cone is formed as the end section of a displaceable sleeve, the said end section appearing conical in the direction of fluid flow, whereby at least the end section is arranged for displacement in a guide sleeve as the counter element.
A dosage feed device for the dosage feed of an additive fluid, the dosage feed device comprising:
- a valve device adjustable by an adjustment device to an open position;
- a dosing cone forming a dosing gap with a counter element, the valve device being arranged following the dosing cone in a direction of fluid flow of the additive fluid;
- the valve device being adjustable by the adjustment device as the valve device moves to an open position without moving the dosing cone relative to the counter element;
- and
- the adjustment device moving the dosing cone to an adjustment position adjusting the dosing gap after the valve device has first moved to the open position.
