FIELD: valves production.SUBSTANCE: invention relates to production of pipeline valves, in particular, to production of elastic compensator inserts and damper of pulsations of working medium pressure pipelines for transportation of liquid media. Flexible compensator insert with pressure pulsation damper comprises cover and sealing layers of rubber cord layers and flanges, at that inside insert along longitudinal axis of pressure pulsation damper is mounted at one end of pulsation damper is secured with at least two ribs to flange flexible compensatory insert, and other end can be fixed with at least two ribs to flange flexible compensatory insert rigidly or in movable manner.EFFECT: combining functions of compensation of relative movements of pipelines and function of effective reduction of hydrodynamic noise generated by working fluid flow in pipeline.3 cl, 2 dwg |
