Abstract

PURPOSE:To prevent vibrator from being adhered with liquid drop such as waterdrop condensed in a pipe by forming liquid drop penetration preventing parts such as ring grooves or ring projections around openings attached to the peripheral wall of the pipe so as to surround the opening. CONSTITUTION:Openings 2a and 2b and fitting parts 3a and 3b are attached to a pipe 1 and acoustic vibrators 4a and 4b are accomodated in the fitting parts 3a and 3b. Ringlike minor projections 5a and 5b are formed around the openings 2a and 2b so as to surround the openings 2a and 2b and ring grooves 6a and 6b are formed around the projections 5a and 5b so as to surround the projections 5a and 5b.
