1. Indlela yokucoca
I-slag ye-welding, irusi kunye ne-slag kumbhobho zibangela ukuvaleka okanye ukuxinana kwi-orifice, inxalenye yesikhokelo kunye nomngxuma olungeleleneyo wesigqubuthelo sevalve esezantsi, okukhokelela ekutsaleni kunye nokukrweleka kumphezulu wondoqo wevalve kunye nomphezulu wesikhokelo, kunye nokuhlenga kumphezulu wokutywina. Oku kwenzeka rhoqo kwisigaba sokuqala sokusebenza kwenkqubo entsha nasemva kokulungiswa ngokutsha. Le yeyona mpazamo ixhaphakileyo. Kule meko, kuyimfuneko ukususa i-slag yokucoca, kwaye ugaye ukuba indawo yokutywina yonakaliswe; kwangaxeshanye, vula iplagi esezantsi ukugungxula i-slag ewela kwisigqubuthelo sevalvu esezantsi ukusuka kumngxunya webhalansi, kwaye ugungxule umbhobho. Ngaphambi kokuqalisa ukusebenza, ivalve yokulawula iya kuvulwa ngokupheleleyo kwaye i-medium iya kuhamba ixesha elide ngaphambi kokuba ingene ekusebenzeni okuqhelekileyo.
2. Indlela yokucoca yangaphandle
Xa i-valve eqhelekileyo isetyenziselwa ukulawula i-medium ekulula ukuyikhupha kwaye iqulethe amasuntswana aqinileyo, ihlala ivaliwe kwi-orifice kunye nesikhokelo. Irhasi egungxulwayo kunye nomphunga zinokudityaniswa kwiplagi esezantsi yesivalo sevalve esezantsi. Xa ivalve ivaliwe okanye ibambekile, vula igesi yangaphandle okanye ivalve yomphunga ukugqiba umsebenzi wokugungxula ngaphandle kokuhambisa ivalve yokulawula, ukuze ivalve isebenze ngokuqhelekileyo.
3. Ukufakwa kwesihluzo sombhobho
Kwivalve encinci yokulawula, ngakumbi ivalve encinci yokulawula ukuhamba, ukucocwa kwayo kuncinci kakhulu, kwaye akufuneki kubekho i-slag phakathi. Kwimeko yokuvaleka, kungcono ukufakela isihluzo kumbhobho phambi kwevalve ukuqinisekisa ukuhamba okugudileyo kophakathi. Kwivalve yolawulo enendawo yokumisa, isithuba asisebenzi ngokuqhelekileyo, kwaye eyona mpazamo ixhaphakileyo kukuvaleka kwe-throttle port yayo. Ngoko ke, xa usebenza ne-positioner, umthombo womoya kufuneka uphathwe kakuhle. Indlela yesiqhelo kukufakela isihluzo somoya ivelufa yokunciphisa uxinzelelo kumbhobho womthombo womoya phambi kwesibekeli-ndawo
4. Yandisa i-throttle clearance
Umzekelo, amasuntswana aqinileyo phakathi okanye i-welding slag kunye nomhlwa ohlanjwe kumbhobho akakwazi ukudlula kwi-orifice ye-throttling kwaye ibangele ukuvala, i-jamming kunye nezinye iimpazamo. Indawo eshukumayo enendawo enkulu evuthuzayo, enje ngesiseko sevalvu kunye nomkhono onefestile kunye nendawo evulekileyo yokuthontsiza, ingasetyenziswa endaweni yoko. Ngenxa yokuba indawo ye-throttling igxininiswe kunokuba isasazwe ngokujikelezayo, impazamo inokupheliswa ngokulula. Ukuba sisitulo esinye okanye isitulo esiphindwe kabini, undoqo wevalve omile okwe-plunger unokutshintshwa ube ngumbindi wevalve omilise okwe-V okanye ivalve yomkhono. Ngokomzekelo, i-valve yesitulo esiphindwe kabini kwisityalo sekhemikhali sihlala sinamathele, ngoko kuyacetyiswa ukuba kusetyenziswe i-sleeve valve, kwaye ingxaki ixazululwa ngokukhawuleza.
5. Indlela yokukhuhla ephakathi
Ngokusebenzisa amandla okukhuhla okuphakathi ngokwawo, inokukhuhla kwaye isuse izinto ezilula ukudlula kunye nokubhloka, ukuze kuphuculwe umsebenzi ochasene nokuthintela wevalve. Iindlela eziqhelekileyo zezi zilandelayo: ① utshintsho kuhlobo oluvaliweyo; ② sebenzisa umzimba wevalvu olungelelanisiweyo; ③ beka i-throttle orifice kweyona ndawo imbi kakhulu, kwaye ubeke ingqalelo ekuphuculeni ukuxhathisa kokhukuliseko lwemathiriyeli ye-throttle.
6. Indlela ethe ngqo itshintshelwe kwindlela ye-angular
Ukuqukuqela okuthe tye kuguquguqukile, indlela yokuqukuqela intsonkothile, kwaye kukho iindawo ezininzi ezifileyo kumngxuma ophezulu nasezantsi, obonelela ngendawo yemvula ephakathi. Uqhagamshelo lwe-angular, eliphakathi ngokungathi liqukuqela kwi-90 ℃ ingqiniba, ukusebenza kakuhle kokukhuhla, indawo encinci efileyo, kulula ukuyilwa kumgca wokuqukuqela. Ngoko ke, xa ivalve yokulawula ngokuthe ngqo ivalwe kancinci, ingatshintshwa ibe yivalve ye-angle.
