The present invention relates to a kind of organic metal-free catalysts containing both electrophilic and nucleophilic dual-functions, preparation methods of making the same, and uses thereof. The organic metal-free catalysts in the present invention have the chemical structure shown in formula (I): Compared with the metal-free organic polymerization catalytic systems that have been reported before, the organic metal-free catalysts in this invention have the combined advantages of simple preparation, high reactivity, easy operation, low cost, wide applicability, easy for industrial production.

Organic metal-free catalysts with electrophilic and nucleophilic dual-functions, preparation methods of making the same, and uses thereof

A flow control device for use in a heat exchange system, including: a housing, a movable valve member and a drive control member, the housing being formed to have a mounting cavity, a first interface and a second interface, while the drive control member includes a control unit, a power output unit, a magnetic element and a detection element; the power output unit provides power to the movable valve member, while the detection element and the control unit are electrically connected, and the magnetic element and the power output unit are mutually assembled and oppositely fixed, the power output unit may drive the magnetic element to rotate; the detection element and the magnetic element are oppositely disposed, the detection element being located within the range of the magnetic field of the magnetic element, the detection element may sense a magnetic pole change of the magnetic element.

Flow control device, and control system and control method therefor

A flow control apparatus for a heat exchange system of a vehicle, including a housing, a valve cartridge assembly, and a control part. A first protrusion is provided on the housing; correspondingly, a second protrusion is provided on a shell of the control part; the first protrusion and the second protrusion are assembled and engaged; a first valve plate is sealed from a second valve plate, so that the seal performance of a product can be improved.
