Abstract

Inventia se refera la un dispozitiv de etansare a unui circuit hidraulic printr-o flansa prin care este circulat de la suprafata un fluid sub presiune în vederea actionarii unei supape de siguranta montate în cuprinsul unei garnituri de tevi de extractie-a unui cap principal de suspendare a unor coloane de burlane de tubare a unei gauri forate si a garniturii amintite, fata de exterior. Dispozitivul conform inventiei, este alcatuit din niste inele metalice, superior si inferior, realizate fie dintr-un material cu o duritate mai mica decât a materialului din care este realizat un agatator, cum ar fi cupru, bronz, aluminiu, plumb sau otel cu un continut scazut de carbon, fie dintr-un material cu o duritate mai mare decât cea a materialului din care este realizat agatatorul, cum ar fo otel cu un continut ridicat de carbon, plasate deasupra si respectiv dedesubtul unui canal circular practicat în agatator si având în sectiune longitudinala forma unui triunghi dreptunghic cu vârful dispus spre în sus si respectiv spre în jos...
