<p>PCT No. PCT/FI86/00078 Sec. 371 Date Feb. 26, 1987 Sec. 102(e) Date Feb. 26, 1987 PCT Filed Jul. 7, 1986 PCT Pub. No. WO87/00455 PCT Pub. Date Jan. 29, 1987.The present invention relates to a flushing apparatus for cleaning a piping system (2) internally. The object of the invention is to achieve efficient cleaning without the use of equipment heavily overdimensioned in relation to the nominal flow through the piping system. According to the invention, use is made of a pump (4) having an operational pressure essentially higher than the pressure fall of the piping system at a turbulent flow, in combination with at least one pressure liquid accumulator (21). The flushing circuit includes at least one blocking valve (15, 15a) which is opened upon reaching intended (maximal) pressure, thereby producing a powerful flow pulse through the piping system (2).</p> |
