Title:
ELECTROMAGNETIC FLOW COUPLER
Document Type and Number:
Japanese Patent JPS63190550
Kind Code:
A
Abstract:

PURPOSE: To obtain an annular electromagnetic flow coupler, easy in manufacturing and high in performance, by a method wherein the inner and outer walls of a flow passageway and partitioning plates, provided in the flow passageway, are constituted of only a corrosion-resistant material against conductive fluid in the flow passageway.

CONSTITUTION: An annular flow passageway inner pipe 1, an annular flow passageway outer pipe 2 and an partitioning plate 3 are manufactured by an corrosion-resistant material such as stainless steel for example, which is corrosion-resistant against conductive fluid, such as liquid metallic sodium for example which flows through a flow passageway, while these parts are welded to manufacture an annular flow passageway. Next, insulating materials 4, worked or sintered cylindrically and the inner pipe 5 as well as an outer pipe, one of strength members and having a large thickness, are incorporated whereby an electromagnetic flow coupler is 1 constituted. According to such a constitution, the inner and outer pipes 1, 2 of the annular flow passageway may be made thin and an equivalent resistance against the leakage of electric current in a direction along side walls contacting with the conductive fluid may be increased, since the inner and outer pipes 1, 2 of the annular flow passageway are not strength members: therefore, the performance of the electromagnetic flow coupler may be improved.
