Abstract

Inventia se refera la un regulator direct de presiune cu posibilitatea de a functiona ca regulator proportional integral sau bipozitional integral cu mentinerea automata a valorii prescrise a presiunilor foarte joase de exemplu 1,6x10 la puterea 7 Pa, din instalatiile tehnologice. Regulatorul conform inventiei este format dintr-un robinet echilibrat actionat de catre un servomotor multietajat al carui sistem mobil este etansat cu membrane manseta subtiri, elastice nearmate, care asigura deplasari ale sistemului mobil independent de marimea diametruluilor si a benzii de proportionalitate; o contragreutate însurubata în axul sistemului mobil, pentru functionarea regulatorului ca bipozitional, cat si un robinet cu ac pe conducta de alimentare a servomotorului, pentru obtinerea efectului de integrare.The invention relates to a direct pressure regulator with the possibility to function as a full proportional integral or integral biphasic regulator with automatic preservation of the prescribed value of the very low pressures, for example 1.6x10 at the power of 7 Pa, from the technological installations. The regulator according to the invention consists of a balanced valve actuated by a multi-layered servomotor whose mobile system is sealed with thin, unarmed elastic sleeve membranes which provide moves of the mobile system independent of the diameter of the diameters and the band of proportionality; a counterweight screwed into the spindle of the movable system to operate the biphasic regulator, and a tap on the servomotor feed pipe to achieve the integration effect.
