Abstract
The present invention discloses a non-contact flow control system having a totally sealed cavity, comprising a housing, a flow control unit and an operation unit. The housing is provided with a fluid inlet, a fluid outlet, and a fluid channel extending between the fluid inlet and the fluid outlet; the flow control unit is arranged in the fluid channel and the operation unit is arranged on an outer side of the housing, wherein the operation unit comprises an operation element and an outer magnet fixed on the operation element; the flow control unit comprises a flow control element and an inner magnet fixed on the flow control element; when the operation element moves relative to the housing, the flow control element can move under the action of a magnetic force between the outer magnet and the inner magnet, thereby changing the flow of the system.
