Iyini isakhiwo kanye nomgomo wokusebenza we-valve yokudlula ithuluzi lokubhoboza?

Ivalvu yokubhoboza ithuluzi lokubhoboza iyivalvu yokuphepha eyisipele yohlelo lokujikeleza kwegazi. Uma umlomo we-drill bit ogcwele uvaliwe ngenxa yezizathu ezahlukahlukene futhi umthombo ungabulawa, ukuvula ivalvu yokubhoboza ithuluzi lokubhoboza kungabuyisela ukujikeleza okuvamile koketshezi lokubhoboza futhi kuqhubeke. Emisebenzini efana nokubulala umthombo, ngaphansi kwezimo ezijwayelekile, ngaphambi kokubhoboza ungqimba kawoyela negesi, ivalvu yokubhoboza ithuluzi lokubhoboza ixhunywe endaweni enqunyiwe yentambo yokubhoboza.

1) Isakhiwo se-valve yokudlula ithuluzi lokubhoboza

Isithombe esingenhla siwumdwebo wesakhiwo odwetshiwe wevalvu yokubhoboza ithuluzi lokubhoboza. Yakhiwe kakhulu ngomzimba wevalvu, i-assembly ye-sliding seat sliding sleeve, imbobo ye-bypass, ibhola lensimbi, iphini, indandatho yokuvala yohlobo lwe-“O”, njll.

2) Isimiso sokusebenza se-valve yokudlula ithuluzi lokubhoboza

Uma sekutholakale ukuthi umgodi wamanzi we-drill bit uvaliwe futhi awukwazi ukuvulwa, susa i-kelly bese uphonsa ibhola, bese uxhuma i-kelly ukuze ibhola liwele esihlalweni se-drill tool bypass valve. Ngemva kokupompa ngokunyakaza okuncane, uma nje umfutho wephampu ukhuphuka uye phezulu. Lapho umfutho ufinyelela inani elithile, iphini eliqinile lizonqunywa, okubangela ukuthi isihlalo sephampu siye phansi kuze kube yilapho umgodi we-bypass uvuleka ngokugcwele. Umfutho wephampu uzokwehla, ngaleyo ndlela kusungulwe isiteshi esisha sokujikeleza, futhi umsebenzi wokwakha ungaqala.

3) Ukusetshenziswa kwe-valve yokudlula ithuluzi lokubhoboza

(1) Ukuze kugcinwe uketshezi lokubhoboza emathunjini luhlanzekile, ivalvu yokudlula kufanele ivulwe kusenesikhathi ukuze kuvinjelwe ukuthi imbobo yamanzi ye-drill bit ingavaleki.

(2) Ibhola lensimbi le-bypass valve kufanele lilungiswe futhi libekwe ngaphambi kokusetshenziswa ukuze likwazi ukufinyelelwa ngesikhathi uma kudingeka.

(3) Ukuze kuqinisekiswe ukuthi umkhono oshelelayo wembobo yokudlula yevalvu yokudlula edingekayo ungavulwa kahle, ngokuvamile kunconywa ukuthi ivalvu yokudlula ifakwe phakathi kwekhola yokubhoboza kanye nepayipi lokubhoboza noma ibanga elingamamitha angu-30 kuya kwangu-70 ukusuka kuvalvu yokuhlola. Amavalvu okudlula emithombo evundlile kanye nemithombo ephambukile kakhulu afakwa kumathuluzi okubhoboza engxenyeni yomthombo engama-50 kuya kwangu-70°.

(4) Ivalvu yokubhoboza ithuluzi lokubhoboza iyadingeka ukuthi iphathwe ngokwendlela yokusebenzisa amathuluzi akhethekile okungena emgodini. Kuyadingeka ukudala ikhadi lokurekhoda ukuze lirekhode ngokuningiliziwe isikhathi sokusetshenziswa komgodi kanye nezinye izilinganiso ezifanele. Ngaphambi komsebenzi ngamunye wokubhoboza, ochwepheshe kanye nababhobozi bazohlola ukuthi kukhona yini ukuvinjelwa, ukuvuza kanye nokuvuza. Ukwehluleka kokuvala, njll.
