description The invention relates to a hydraulically-controlled cock with a nominal diameter Dn 80, Dn 100 and Dn 150, which has water with a temperature ranging between 5...90°C and a maximum working pressure of 10 bar as working medium, said cock being used for irrigation arrangements, cold or domestic water distribution networks or fire-fighting water networks. According to the invention, the cock comprises a body () wherein there axially moves a valve (), a frontal sealing (), a radial sealing () guiding the spring (), a cover () with a nozzle () for regulating the opening speed, the cover () being fixed to the body () by some screws () tightened with the corresponding nuts () and sealed with a flat packing (), a manually-driven opening-closing distributor (), in which the position of the valve () is regulated in stages by a limiting screw (), the flow rate being estimated on the basis of the pressure difference measured by the manometers () and the opening stroke. Invenţia se referă la un robinet comandat hidraulic, cu diametrul nominal Dn 80, Dn 100 şi Dn 150, ce are ca mediu de lucru apa cu temperaturi cuprinse între 5...90°C şi presiunea maximă de lucru de 10 bar, robinetul fiind utilizat la amenajări de irigaţii, reţele de distribuţie de apă rece sau menajeră, sau reţele de apă pentru stingerea incendiilor. Robinetul conform invenţiei este constituit dintr-un corp () în care se deplesează axial un ventil (), o etanşare frontală (), o etanşare radială () care ghidează arcul (), un capac () cu o duză () pentru reglarea vitezei de deschidere, capacul () fiind fixat de un corp () cu nişte şuruburi () strânse cu piuliţele () aferente, şi etanşat cu o garnitură () plată, un distribuitor () acţionat manual, cu rol de închidere-deschidere, la care se reglează în trepte poziţia ventilului () de către un şurub () limitator, estimarea debitului făcându-se pe baza diferenţei de presiune măsurată cu manometrele (), şi a cursei de deschidere.
