I-1, Indawo yokuvuza nesimo: amabhawodi e-flange axhumayo ezinhlangothini zombili zokuvuza komzimba we-valve ye-DN150. Ngenxa yokuthi igebe lokuxhuma kwe-flange lincane kakhulu, akunakwenzeka ukuqeda ukuvuza ngokujova i-sealant esikhaleni. Indawo yokuvuza iyisitimu, izinga lokushisa lesistimu yokuvuza lingu-400 ~ 500 ℃, futhi ingcindezi yesistimu ingu-4MPa.
2, Indlela yokwakha yokuvala ngokokuhlola kwensimu yengxenye evuzayo, ukuze kufinyelelwe ukuvala okulinganiselwe, indlela yokulungisa engaguquki isetshenziselwa ukuqukatha indawo yokuvuza, ukwakha imbobo yokuvala, nokujova isivalo ukuze kuqedwe ukuvuza.
1. Idizayini yokulungisa
(1) Ukunqunywa kwesakhiwo somdlalo
① Iqukethe indawo yokuvuza futhi umise imbobo yokuvala phakathi kwe-valve yomzimba kanye ne-flange yepayipi exhuma i-nipple flange. Ukuze kuvinjwe ukuvuza kabusha lapho kuvuza khona igebe phakathi kwe-valve yomzimba kanye ne-flange ngenxa yokubamba ingcindezi, i-annular cavity izosethwa ngokuqondana phakathi kwe-clamp kanye nonqenqema olungaphandle lwe-valve body flange ukuze kujovwe iglue.
② Ngesikhathi senqubo yokujova i-ejenti yokunciphisa i-flange, ukulungiswa kulula ukugudlukela ohlangothini lwe-flange encane yobubanzi, ngakho-ke isilinganiso somkhawulo sokuthinta izinyo siyamukelwa.
(2) Umdwebo wesakhiwo kanye nobukhulu obufanele besakhiwo esizokwakhiwa kuboniswe kuMfanekiso 1.
2. Ukukhethwa kwe-sealant nokulinganisa umthamo
(1) I-sealant izoba yi-txy-18#i-sealant ngokuya ngezinga lokushisa lesistimu yokuvuza kanye nezici zengxenye yokuvuza. I-sealant inokumelana nokushisa okuhle kakhulu, ukumelana okuphakathi nokusebenza kwenqubo yomjovo, kulula ukusungula isakhiwo sokuvala umfaniswano nesiminyene, futhi ukubekwa uphawu kungagcinwa kuzinzile isikhathi eside.
(2) Kulinganiselwa ukuthi i-4.5kg sealant iyadingeka endaweni yokuvuza ehlangene.
3. Umsebenzi wokwakha
(1) Ngesikhathi sokufakwa kwesakhiwo, ngenxa yokuthintana kwezinyo, ububanzi bangaphakathi bethiphu lezinyo buncane. Ngesikhathi sokufakwa, udonga lwangaphandle lwesakhiwo ludinga ukushaywa eduze neringi ukuze luthinte isiphetho sezinyo futhi lubambe umkhawulo.
(2) Ngemuva kokuthi umsebenzi wokujova i-ejenti usuphothuliwe, i-clamp, umzimba we-valve kanye ne-flange annular cavity kuyojovwa emgodini wokuvala, bese umjovo we-ejenti ophakathi nendawo uyokwenziwa. Inqubo yokujova i-ejenti kufanele ilinganiswe, futhi inake umjovo owengeziwe kanye nokucindezelwa ukuvimbela ukukhululeka kwengcindezi.
(3) Ngemuva kokuthi i-sealant selashiwe, yenza umjovo ongeziwe wendawo kanye nokucindezelwa ngemuva kokubona umphumela ukuvimbela ukukhululeka kwengcindezi, bese uvala imbobo yomjovo.
