Abstract

Inventia se refera la un dispozitiv pentru depresurizarea incintelor de înalta presiune de la presele izostatice. Dispozitivul pentru depresurizarea incintelor, conform inventiei, are în componenta, un corp prevazut cu niste canale care comunica cu incinta de înalta presiune, respectiv cu evacuare, precum si un canal cilindric în care este dispusa o tija a unui piston. Tija are un capat tronconic în care este executat un canal pentru etansare. O alta tija a pistonului actioneaza o roata dintata care, la rîndul ei, actioneaza un potentiometru liniar a carui tensiune este comparata, prin intermediul unui bloc comparator, cu tensiunea unui potentiometru. Pistonul este actionat de la o sursa de presiune printr-un distribuitor, o supapa deblocabila si un reculator proportional de debit comandat de semnalul dat de un traductor electronic de presiune, prin intermediul unui regulator electronic derivativ.The invention relates to a device for depressurizing high pressure enclosures from isostatic presses. According to the invention, the device for depressurizing the enclosures comprises a body provided with some channels communicating with the high pressure chamber, respectively with an outlet, as well as a cylindrical channel in which a piston rod is disposed. The stem has a frusto-conical end in which a sealing channel is executed. Another piston rod acts on a toothed wheel which, in turn, acts on a linear potentiometer whose voltage is compared, by means of a comparator block, to the voltage of a potentiometer. The piston is operated from a pressure source through a distributor, a releasable valve, and a proportional flow recool, controlled by the electronic pressure transducer signal, by means of a derivable electronic regulator.
