Ukufakelwa kweevalvu zebhola ezidityanisiweyo ngokupheleleyo
(1) Ukuyiphakamisa. Ivalvu kufuneka iphakanyiswe ngendlela echanekileyo. Ukukhusela isiqu sevalvu, musa ukuyibophelela ityathanga lokuyiphakamisa kwivili lesandla, kwibhokisi yegiya okanye kwi-actuator. Musa ukususa izigqubuthelo zokukhusela kuzo zombini iziphelo zesingxobo sevalvu ngaphambi kokuyidibanisa.
(2) Ukuwelda. Uqhagamshelo nombhobho oyintloko luwelding. Umgangatho womthungo wokuwelda kufuneka uhlangabezane nomgangatho we-"Radiography of Welded Joints of Disk Flexion Fusion Welding" (GB3323-2005) Grade II. Ngokwesiqhelo, ukuwelda okukodwa akunakuqinisekisa ngokupheleleyo zonke iimfaneleko. Ke ngoko, xa u-odola ivalvu, umenzi kufuneka acele umenzi ukuba ongeze i-1.0m kuzo zombini iziphelo zevalvu. Ityhubhu yesleeve, xa umthungo wokuwelda ungaweldingwanga, kukho ubude obaneleyo bokunqumla umthungo wokuwelda ongaweldingwanga kwaye uphinde uwuwelding. Xa ivalvu yebhola kunye nombhobho ziweldingwanga, ivalvu kufuneka ibe kwindawo evulekileyo ngokupheleleyo eyi-100% ukuthintela ivalvu yebhola ukuba yonakale yi-slag yokuwelda etshixayo, kwaye kwangaxeshanye uqinisekise ukuba ivalvu. Ubushushu besitywina sangaphakathi abudluli kwi-140 degrees Celsius, kwaye amanyathelo okupholisa afanelekileyo anokuthathwa ukuba kuyimfuneko.
(3) Ukwakhiwa kwequla levalvu. Yamkela uyilo olukhethekileyo lwesakhiwo kwaye ineempawu zokungagcinwa. Ngaphambi kokungcwaba, faka i-Pu ekhethekileyo yokulwa nokugqwala ngaphandle kwevalvu. Isiqu sevalvu solulwe ngokufanelekileyo ngokobunzulu bomhlaba, ukuze abasebenzi bakwazi ukugqiba imisebenzi eyahlukeneyo emhlabeni. Emva kokuba umngcwabo othe ngqo wenziwe, kwanele ukwakha iqula elincinci levalvu. Kwiindlela eziqhelekileyo, ayinakugqunywa ngqo, kwaye kufuneka kwakhiwe imigodi emikhulu yevalvu, nto leyo ekhokelela kwindawo evaliweyo eyingozi, engafanelekanga ekusebenzeni ngokukhuselekileyo. Kwangaxeshanye, umzimba wevalvu ngokwawo kunye neendawo zokudibanisa ibolt phakathi komzimba wevalvu kunye nombhobho ziya kugqwala, nto leyo eya kuchaphazela ubomi benkonzo yevalvu.
Yintoni ekufuneka iqwalaselwe xa kulungiselelwa ivalvu yebhola edityanisiweyo ngokupheleleyo?
Ingongoma kukuba xa ivaliwe, kusekho ulwelo oluxinzelelweyo ngaphakathi komzimba wevalvu.
Ingongoma yesibini kukuba ngaphambi kokulungiswa, qala ukhulule uxinzelelo lombhobho uze ugcine ivalvu ikwindawo evulekileyo, uze unqumle umthombo wamandla okanye wegesi, uze ukhuphe i-actuator kwisibiyeli, kwaye kuphela emva kokuba zonke ezi zinto zingasentla zilungisiwe.
Ingongoma yesithathu kukufumanisa ukuba uxinzelelo lwemibhobho ephezulu nesezantsi yevalvu yebhola lukhululekile ngokwenene, emva koko ukuqhaqha kunye nokubola kungenziwa.
Amanqaku amane kufuneka aqapheleke kwinkqubo yokuqhaqha nokudibanisa kwakhona, ukuthintela umonakalo kumphezulu wokutywina kwamalungu, ukusebenzisa izixhobo ezikhethekileyo ukususa i-O-ring, kunye nokuqinisa iibholithi kwiflange ngokulinganayo nangokuthe ngcembe nangokulinganayo ngexesha lokuhlanganiswa.
Amanqaku amahlanu: Xa ucoca, iarhente yokucoca esetyenzisiweyo kufuneka ihambelane nezixhobo zerabha, izixhobo zeplastiki, izixhobo zesinyithi kunye nezixhobo zokusebenza kwivalvu yebhola. Xa isixhobo sokusebenza siyigesi, ipetroli ingasetyenziselwa ukucoca izixhobo zesinyithi, kwaye Kwizixhobo ezingezizo ezesinyithi, kufuneka usebenzise amanzi acocekileyo okanye utywala ukucoca. Izixhobo ezibolileyo zicocwa ngokucwiliswa emanzini, kwaye iindawo zesinyithi zezinto ezingezizo ezesinyithi ezingabolanga zicocwa ngelaphu lesilika elicocekileyo nelicolekileyo elifakwe kwisixhobo sokucoca, kwaye yonke igrisi enamathele kumphezulu wodonga kufuneka isuswe. , ukungcola nothuli. Kwakhona, ayinakuhlanganiswa kwangoko emva kokucoca, kwaye inokwenziwa kuphela emva kokuba isixhobo sokucoca siphumile.
