Waa maxay mabda'a shaqada iyo isticmaalka kelly valve?

1. Ujeedada kelly valve

Kelly valve waa gacanta gacanta lagu hago ee nidaamka wareegga xadhkaha daloolka waana mid ka mid ah aaladaha wax ku oolka leh ee looga hortagayo qarxinta. Kelly valves waxaa loo qaybin karaa valves sare iyo kelly valves hoose. Waalka sare ee kelly waxa loo isticmaalaa inta u dhaxaysa dhamaadka hoose ee tuubada iyo kelly; waalka hoose ee kelly waxa loo isticmaalaa inta u dhaxaysa dhamaadka hoose ee kelly iyo wadajirka ilaalinta kelly. Dareeraha qodista ayaa si xor ah ugu qulquli kara waalka kelly iyada oo aan cadaadis la saarin. Isticmaal furaha gaarka ah si aad u damiso 90° sida ku cad tilmaamaha si aad u shido oo aad u damiso.

2. Qaab dhismeedka Kelly valve iyo mabda'a shaqada

Waalka kelly ee sare iyo kan hoose waxa uu ka kooban yahay jidhka, kursiga kubbadda hoose, il, furaha hawlgalka, waalka kubbadda, giraanta kaydinta furan, kursiga kubbadda sare, gacangashiga gacanta, giraanta xajinta laastikada ah iyo shaabad Mabda'a xidhidhiyaha ayaa ah in guga uu taageero kursiga kubbadda si uu kubbadda u dhigo oo uu u yeesho horudhac gaar ah. Kubadda iyo shaabadda kursiga kubbadda ayaa isku dhow. Marka kubbadda la sii daayo, indhaha biyuhu waa kuwo aan xannibnayn. Marka la xiro, dusha sare ee wareega ayaa daboolaya dhammaan indhaha biyaha. Cadaadiska annulus gudaha wuxuu ku shaqeeyaa kubbadda, taasoo ka dhigaysa kubbadda iyo kursiga kubbadda xaalad cadaadis sare leh.

3. Sida loo isticmaalo kelly valve

(1) Kahor intaanad isticmaalin, isticmaal furaha qalliinka si aad u rogrogto furaha qalliinka si aad u aragto in uu si dabacsanaani u rogman karo, meel ama meel ka baxsan;

(2) Kadib markaad isku xirto darafyada sare iyo hoose ee kelly, isticmaal furaha mar labaad si aad u tijaabiso dabacsanaanta furayaasha hawlgalka ka hor intaadan ceelka hoos u dhigin;

(3) Marka laad ama afuufo ay ka dhacaan kelly ceelka, waalka sare ama hoose ee kelly waa in la xidhaa meesha ugu dhow;

(4) Inta lagu jiro hawlgalka caadiga ah, xidh valve hoose ka hor inta aanad dejin kelly si aad uga hortagto dareeraha daloolista inuu ku firdhiyo sagxadda qodista;

(5) Ku adkeyso inaad si joogto ah u furto oo aad u xidho gusyada sare iyo kuwa hoose ee kelly. Tusaale ahaan, marka la isku xidho hal gabal ama la isticmaalayo cowska sare iyo hoose ee kelly ee la dhaqaajin karo waqtiyo joogto ah, si looga fogaado in la daxaleeyo oo aan awoodin in si caadi ah loo furo loona xiro;

(6) Kadib marka la isku xiro hal gabal, tuubada xirxiran waa in la furo waqtiga si looga fogaado qabashada bamka marka bamka la bilaabayo;

(7) Furaha waalka furka waa in la dhigaa meel ka durugsan ceelka si looga ilaaliyo in uu ku dhaco ceelka ama uu lumo;

(8) Markaad dooranayso valve fur, hubi in cadaadiskiisa shaqo ee ugu badan uu la socdo heerka cadaadiska kooxda ka-hortagga afuufka madaxa.
