Abstract

Inventia se refera la un bac din cauciuc, inelar, folosit la un prevenitor vertical de eruptie cu actionare hidraulica - care este montat deasupra unei gauri în foraj - avînd rolul de a etansa de exemplu, un spatiu inelar dintre o garnitura de prajini de forare si un perete al gaurii sau o coloana de burlane intermediara fata de exterior. Bacul, conform inventiei este alcatuit dintr-un corp din cauciuc de forma inelara, simetric, strabatut de cater un canal longitudinal, prin care poate trece o garnitura de prajini de forare, avînd niste caneluri, superioare si inferioare situate între niste armaturi, superioare si inferioare situate echidistante, articulate doua cîte doua, cu ajutorul unor bolturi, dispuse radial într-un plan transversal de simetrie si egal departate de axa longitudinala de simetrie. Armaturile superioare si inferioare au niste capete superioare, si inferioare unite între elee prin intermediul a cîte unei foi de arc, ceea ce favorizeaza......The invention relates to an annular rubber bin used in a vertical hydraulic-action eruption preventer - which is mounted above a drilling hole - having the role of, for example, sealing an annular space between a borehole and a wall of the hole or a column of intermediate spouts from the outside. According to the invention, the bake consists of a symmetrically shaped annular rubber body which is provided with a longitudinal groove through which a borehole can be passed, having some upper and lower grooves located between some upper and the two equidistant lower ones, articulated two by two bolts, radially disposed in a transverse plane of symmetry and equidistant from the longitudinal axis of symmetry. The upper and lower arms have upper and lower ends joined together by an arched sheet, which favors ......
