Zusammenfassung: | 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.
L'invention porte sur un dispositif sensible à la pression, configuré de telle sorte que la pression de fluide est détectée par une section de détection de pression (2) par introduction du fluide à travers un accouplement fileté femelle (1) dans un récipient de pression qui comprend un élément capuchon (21), l'accouplement fileté femelle (1) et l'élément capuchon (21) étant reliés de façon fiable entre eux sans brasage, et le procédé de production étant simplifié, de façon à réduire le stock intermédiaire de produits qui sont traités. Un accouplement intermédiaire en acier inoxydable (3) est disposé entre l'accouplement fileté femelle en laiton (1) et l'élément capuchon en acier inoxydable (21). Une surface inclinée (13) est formée entre le trou fileté (11) et un trou cylindrique (12) de l'accouplement fileté femelle (1). Une section cylindrique (31) de l'accouplement intermédiaire (3) est disposée dans le trou cylindrique (12) de l'accouplement fileté femelle (1), et la périphérie de la section de contact entre une section plate (31A) de la section cylindrique (31) et une section plate (21A) de l'élément capuchon ( |
