I-IBOP, isivikelo sangaphakathi sokuqhuma kwe-top drive, sibizwa nangokuthi i-top drive cock. Emsebenzini wokubhoboza uwoyela negesi, ukuqhuma kwe-blowout kuyingozi abantu abangafuni ukuyibona kunoma iyiphi i-rig yokubhoboza. Ngoba kusongela ngqo ukuphepha komuntu siqu kanye nempahla yeqembu lokubhoboza futhi kuletha ukungcola kwemvelo. Ngokuvamile, uketshezi olunomfutho ophezulu (uketshezi noma igesi), ikakhulukazi igesi enodaka kanye notshani, luzokhishwa emthonjeni ngesivinini esikhulu kakhulu sokugeleza, kwakha indawo embi kakhulu yeziqhumane zomlilo ezidumayo. Imbangela yengozi ivela oketshezini oluphakathi kwezingqimba zamatshe angaphansi komhlaba, olunomfutho ophezulu ngokungavamile. Lapho kubhobozwa kuze kube yile nkathi, kuzokwenzeka ukushintshashintsha kwengcindezi, futhi ukuqhuma kwe-blowout kuzokwenzeka ezimweni ezimbi kakhulu. Ngokwanda kobuchwepheshe bokubhoboza obungalingani, amathuba okukhahlela nokuqhuma kwe-blowout makhulu kakhulu kunalawo okubhoboza okulinganiselayo okuvamile.
Ihlanganiswe neminye imishini kanye nobuchwepheshe ukuvala imbobo lapho ukukhahlela nokuqhuma kuvela nje, ukuze abasebenzi bakwazi ukulawula ukukhahlela nokuqhuma ngaphambi kokuba kukhiqizwe ukuqhumisa. Ngokwendawo yesiteshi sokuqhumisa, amathuluzi ase-drilling rig angahlukaniswa abe yi-internal blowout preventer, i-annular rotary blowout preventer ekhanda lomthombo kanye ne-ram.
Izinhlobo zama-BOP, njll. Lo mkhiqizo uwuhlobo lokuvimbela ukuqhuma ngentambo yokubhoboza, olubizwa nangokuthi i-top drive cock noma i-plug valve. I-top drive internal blowout preventer ekhiqizwa yinkampani yethu isebenzisa izinto ze-E-grade ezisezingeni eliphezulu njengegobolondo, futhi isakhiwo sayo siqukethe umzimba we-valve, isihlalo se-valve esiphezulu, i-Wave spring, i-valve core, isibambo sokusebenza, i-cross slide block, i-handle sleeve, i-lower split retaining ring, i-lower valve retaining ring, i-upper split retaining ring, i-Support ring, i-retaining ring for hole, i-O-ring seal, njll. I-internal blowout prevent iyi-ball valve ene-metal seal, ene-wave spring recompensation kanye ne-pressure sealing mechanism, enekhono lokuvala elithembekile ngaphansi kwengcindezi ephezulu kanye nengcindezi ephansi. Igcina izinzuzo zesakhiwo sokuklama se-woolen ball valve. Ukuze kufezwe ukuvalwa kwengcindezi ephezulu, kuklanywa indlela yokuvala esekelwa yingcindezi, okwenza ingcindezi yoketshezi oluvaliwe ikhiqize amandla okuvala phakathi kwe-valve core kanye nezihlalo ze-valve eziphezulu nezingezansi, futhi la mandla okuvala adlala indima yokuvala esekelwa yingcindezi.
Ukuze kufezwe ukuvalwa kwengcindezi ephansi, kwaklanywa indlela yokuqinisa intwasahlobo yamagagasi, enikeza amandla adingekayo esihlalweni sevalvu engezansi ukucindezela ibhola. Okwesithathu, lapho ingaphakathi levalvu livaliwe kusukela ngaphansi, intwasahlobo yamagagasi inganikeza amandla okuvala angathinteki umehluko wokucindezela kwengaphakathi levalvu. Isiciko sokuqala esingenisiwe siyamukelwa, futhi siyafaneleka ukuphuma efektri ngemuva kokuhlolwa okune kokucindezela. Umphumela wokushintsha ungatholakala nge-crank noma umkhawulo. Osayizi abahlukahlukene bangenziwa ngezifiso.
