Title:
PRESS-FIT REMOTE DIAPHRAGM ASSEMBLY
Document Type and Number:
WIPO Patent Application WO2001061219
Kind Code:
A3
Abstract:
A remote diaphragm assembly (10) for use in the process control industry is disclosed which can be quickly assembled and disassembled by press-fitting a diaphragm housing (34) and an adapter housing (36) together. The diaphragm housing (34) includes a flexible diaphragm (20) and a first retention ring receiving portion (56). The adapter housing is configured to place the flexible diaphragm (20) in fluid communication with a process fluid (14) in a vessel (16) and includes a second retention ring receiving portion (58). The first and second retention ring receiving portions (56, 58) align to form a retention ring cavity (62). A retention ring (38) is positioned within the retention ring cavity (62) such that portions of the retention ring (38) occupy the first and second retention ring receiving portions (56, 58) to couple the diaphragm housing (34) to the adapter housing (36). Also disclosed is a method for assembling the above-described remote diaphragm assembly (10). The method includes securing a retention ring (38) to either the first or the second retention ring receiving portions (56, 58) and press-fitting the diaphragm housing (34) and the adapter housing (36) together to couple the diaphragm housing (34) to the adapter housing (36).
