Title:
STRUCTURE FOR CONNECTION BETWEEN PRESSURE SENSING SECTION OF PRESSURE SENSITIVE DEVICE AND FEMALE THREADED COUPLING
Document Type and Number:
WIPO Patent Application WO/2011/070655
Kind Code:
A1
Abstract:
A pressure sensitive device configured in such a manner that the pressure of fluid is detected by a pressure sensing section (2) by introducing the fluid through a female threaded coupling (1) into a pressure container which comprises a cap member (21), wherein the female threaded coupling (1) and the cap member (21) are reliably connected together without brazing and the production process is simplified to reduce the intermediate inventory of products being processed.
A stainless steel intermediate coupling (3) is provided between the brass female threaded coupling (1) and the stainless steel cap member (21). A tilted surface (13) is formed between the threaded hole (11) and a cylindrical hole (12) of the female threaded coupling (1). A cylindrical section (31) of the intermediate coupling (3) is fitted in the cylindrical hole (12) of the female threaded coupling (1), and the periphery of the contact section between a flat section (31A) of the cylindrical section (31) and a flat section (21A) of the cap member (21) is welded by laser. A tilted flange section (32) of the intermediate coupling (3) is pressed against the tilted surface (13) by means of a male threaded coupling (5) (FIG. 3) on the piping side to cause the tilted surface (13) and the tilted flange section (32) of the intermediate coupling (3) to be in close contact with each other.
