I-1, indawo yokuvuza kunye nemeko: iibholiti zeflange ezidibanisayo kumacala omabini e-DN150 ivalve yokuvuza komzimba. Ngenxa yokuba i-gap yokudibanisa i-flange incinci kakhulu, akunakwenzeka ukuphelisa ukuvuza ngokufaka i-sealant kwi-gap. Indawo yokuvuza ngumphunga, ubushushu benkqubo yokuvuza yi-400 ~ 500 ℃, kwaye uxinzelelo lwenkqubo yi-4MPa.
2, Indlela yokwakha yokutywina ngokovavanyo lwentsimi yenxalenye yokuvuza, ukuze kuphunyezwe ukutywinwa okulinganiselweyo, indlela yokulungiswa okusisigxina isetyenziselwa ukuqulatha indawo yokuvuza, ukwenza indawo yokutywina, kunye nokutofa i-sealant ukuphelisa ukuvuza.
1. Uyilo lokulungisa
(1) Ukumiselwa kwesakhiwo somdlalo
① Gcina indawo yokuvuza kwaye umisele umngxuma wokutywina phakathi kweflange yomzimba wevalvu kunye neflange yombhobho odibanisa iflange yengono. Ukuze kuthintelwe ukuvuza kwakhona ekuvuzeni okunokwenzeka komsantsa phakathi komzimba wevalvu kunye neflange ngenxa yokubamba uxinzelelo, umngxuma we-annular uya kusekwa ngexesha lokuhlangana phakathi kwe-clamp kunye nomphandle ongaphandle we-valve yeflange yomzimba ukuze kufakwe inaliti yeglue.
② Ngexesha lenkqubo yokutofa kwe-arhente yokunciphisa i-flange, ukulungiswa kulula ukutshintshela kwicala le-flange encinci ye-diameter, ngoko ke umlinganiselo wokukhawulelana nokudibanisa izinyo wamkelwa.
(2) Umzobo wento enye kunye nemilinganiselo efanelekileyo yolwakhiwo olulungiselelwe ulwakhiwo lubonisiwe kuMfanekiso 1.
2. Ukukhetha i-sealant kunye noqikelelo lwedosi
(1) I-sealant iya kuba yi-txy-18#i-sealant ngokobushushu benkqubo yokuvuza kunye neempawu zenxalenye yokuvuza. I-sealant inokumelana nobushushu obugqwesileyo, ukuchasana okuphakathi kunye nokusebenza kwenkqubo yokutofa, kulula ukuseka iyunifomu kunye nesakhiwo sokutywina esixineneyo, kwaye ukutywinwa kunokugcinwa kuzinzile ixesha elide.
(2) Kuqikelelwa ukuba i-4.5kg sealant iyafuneka kwindawo yokuvuza esecaleni.
3. Umsebenzi wokwakha
(1) Ngexesha lofakelo lwezinyo, ngenxa yokudibanisa izinyo, i-diameter yangaphakathi yencam yezinyo incinci. Ngexesha lofakelo, udonga lwangaphandle lwe-fixture kufuneka lubethelwe malunga neringi ukuze lutshintshe isiphelo sezinyo kwaye lubambe umda.
(2) Emva kokuba usebenziso lwenaliti ye-ejenti lugqityiwe, ibamba, umzimba wevalvu kunye ne-flange ye-annular cavity iyakutofwa kumngxuma wokutywina, kwaye inaliti ye-arhente kumngxuma ophakathi iya kwenziwa. Inkqubo yokutofa kwe-ejenti iya kulungelelaniswa, kwaye inike ingqwalasela kwinaliti eyongezelelweyo kunye noxinzelelo lokuthintela ukuphumla koxinzelelo.
(3) Emva kokuba i-sealant iphilisiwe, yenza inaliti eyongezelelweyo yendawo kunye nokunyanzeliswa emva kokuqwalaselwa kwesiphumo ukukhusela ukuphumla koxinzelelo, kwaye emva koko uvale umngxuma wokutofa.
