Ukufakwa kweeValves zeBhola yeBhola ye-Weld
(1) Ukuziphakamisa. Ivalve kufuneka inqunyulwe ngendlela echanekileyo. Ukukhusela i-valve stem, sukubopha i-chain yokuthetha, kwi-pheretheel, i-Gearbox okanye iArgatotor. Sukususa i-cap ekhuselayo kwiziphelo zomibini umkhono we-valve ngaphambi kwe-welding.
(2) I-welding. Unxibelelwano kunye nombhobho ophambili welidle. Umgangatho womthungo we-welding kufuneka uhlangabezane nemigangatho ye "radiology yodityazisiweyo ye-Welding yediski yediski ye-Willing" (GB3333-2005) Ibanga le-II. Ngokwesiqhelo, enye i-welding ayinakuqinisekisa ngokupheleleyo zonke iziqinisekiso. Ke ngoko, xa i-valve, umenzi kufuneka acele umvelisi ukuba enze i-1.0m kuzo zombini iziphelo zevalve. I-Sleeve Tube, kanye nje ukuba i-Welding Seam ayinakwenziwe, kukho ubude obaneleyo ukunqumla i-Selding Seld Doam kwaye uphinde uphinde uphinde. Xa i-valve yebhola kunye nepayipile ye-walve, ivalve ifanele ibe kwimeko ye-100% ivulekileyo yokuthintela ivali ye-ilding ye-ilding rissius, kwaye amanyathelo afanelekileyo okupholisa anokuthathwa xa kukho imfuneko.
(3) Ivalve ilungile Ifumana uyilo olukhethekileyo lolwakhiwo kwaye ineempawu zokulondolozwa kwesondlo. Ngaphambi kokuba ungcwabe, faka isicelo se-purasion echasayo i-anti-colosion ngaphandle kwevalve. I-valve supte inda ngokufanelekileyo ngokobunzulu bomhlaba, ukuze abasebenzi bagqibe imisebenzi eyahlukeneyo emhlabeni. Emva kokuba umngcwabo ngqo uyafezekiswa, kwanele ukwakha isandla esincinci sevalve. Ngeendlela eziqhelekileyo, ayinakungcwatywa ngokuthe ngqo, kwaye i-valve enkulu ye-valve iyakhiwe, ekhokelela kwindawo evaliweyo eyingozi, engahambelani nokusebenza ngokukhuselekileyo. Kwangelo xesha, umzimba wevali ngokwayo kunye neendawo zokunxibelelana eziphakathi kwe-bolt phakathi kwebhulukhwe yevali kunye nombhobho ziya kuchaphazeleka, obuya kuchaphazela ubomi benkonzo yevali.
Yintoni ekufuneka ithathelwe ingqalelo kulondolozo lwe-valve epheleleyo yeBhola yeBhola?
Inqaku lelona xesha livaliweyo, kusekho ulwelo ngaphakathi komzimba wevali.
Inqaku lesibini kukuba ngaphambi kokulondolozwa, ukukhupha i-piidiel uxinzelelo kwindawo evulekileyo, emva koko banqumle umthombo okanye umthombo wegesi, kwaye emva kokuba konke oku kungentla kulungiswa.
Inqaku lesithathu kukufumanisa ukuba uxinzelelo lwe-upstream kunye nemibhobho ye-downkhalda yeValve ivunyelwe nyani, emva koko intle kunye nokungalunganga kunye nokubola kunokwenziwa.
Amanqaku amane kufuneka alumkele inkqubo yokucutha kwaye athintele phantsi, ukuthintela ukonakalisa umphezulu wenxalenye, ukusebenzisa izixhobo ezizodwa zokususa i-o-rings kwiflethi kunye nokuhlwa ngexesha lendibano.
Amanqaku amahlanu: Xa ukucocwa, iarhente yokucoca isetyenzisiwe kufuneka ihambelane namacandelo erabha, iinxalenye zeplastiki, amalungu entsimbi, kunye nendawo yokusebenza kwi-valve yebhola. Xa umsebenzi ophakathi yirhasi, ipetroli inokusetyenziselwa ukucoca iinxalenye zensimbi, kwaye iinxalenye ezingezizo zentsimbi, kufuneka usebenzise amanzi amdaka, kufuneka usebenzise amanzi amdaka okanye utywala ukuze ucoceke. Amacandelo anento ehleliweyo acocwa ngokuhlamba, kunye neenxalenye zentsimbi ezingakhange zibonwe nge-idafu ecocekileyo nelangazelelayo ecocekileyo, kwaye yonke itori enamathele kwindawo yodonga kufuneka isuswe. , ukungcola kunye nothuli. Kwakhona, ayinakuhlanganiswa kwangoko emva kokucocwa, kwaye inokwenziwa kuphela emva kokuba iarhente yokucoca ikhutshiwe.
