Verbindungsanordnung für ein Durchflussregelventil

摘要

A flow control valve coupling structure that does not require complicated machining and facilitates the installation of a flow control valve. The coupling structure includes a fitting portion (18) having a male thread (23) that is formed on a peripheral surface of the flow control valve, A coupled member (H) has a coupling hole (31) to receive the flow control valve. A cylindrical elastic sealing member (12) is engaged with the coupling hole to seal the space between the flow control valve and the coupling hole. The elastic sealing member has an inner surface defining a mounting hole (32) in which the fitting portion is fitted. A female thread (32A) is formed on the inner surface and is mated with the male thread of the fitting portion.
