Umbhobho wesinyithi othuliweyoluhlobo lwezixhobo zombhobho ngokubanziisetyenziswa ekunikezelweni kwamanzi, ekutsaleni amanzi, ekudluliseleni igesi nakwezinye iindawoIneempawu zokuba namandla aphezulu, ukumelana nokugqwala kunye nobomi obude benkonzo. Uluhlu lobubanzi bombhobho wesinyithi we-DINSEN ductile luDN80～DN2600 (ububanzi yi-80mm～2600mm),ngokubanzi ziimitha ezi-6 kwaye zingenziwa ngokwezifiso.Inqanaba loxinzelelo: lidla ngokwahlulwahlulwa lube ludidi lwe-T (uxinzelelo oluphantsi), uhlobo lwe-K (uxinzelelo oluphakathi) kunye nohlobo lwe-P (uxinzelelo oluphezulu).Cofa ukuze ufumane ikhathalogu yeepayipi zesinyithi ezithambileyo.
Kwiindlela zoqhagamshelo lwenkqubo yepayipi yesinyithi ethambileyo, iDINSEN izishwankathela ngolu hlobo lulandelayo:
1.Uqhagamshelo lwesokhethi yohlobo lwe-T:Yi-interface eguquguqukayo, ekwabizwa ngokuba yi-slide-in interface, eyi-interface eqhelekileyo kwiipayipi zentsimbi ezithambileyo zasekhaya. Uxinzelelo loqhagamshelwano phakathi kweringi yerabha kunye nesokhethi kunye ne-spigot lwenza isitywino solwelo. Isakhiwo sesokhethi siqwalasela indawo kunye ne-angle yokuphambuka kweringi yerabha, sinokuzivumelanisa nesiseko esithile, sinokuxhathisa inyikima ethile, sineempawu zesakhiwo esilula,ukufakwa okulula kunye nokutywinwa kakuhle, njl. Uninzi lweepayipi zesinyithi ezithambileyo ezithengiswayo zisebenzisa olu qhagamshelo.
Amanyathelo athile: 1. Coca isokhethi kunye ne-spigot. 2. Faka i-lubricant eludongeni lwangaphandle lwe-spigot kunye nodonga lwangaphakathi lwesokhethi. 3. Faka i-spigot kwisokhethi ukuqinisekisa ukuba ikwindawo yayo. 4. Vala ngeringi yerabha.
2. Uqhagamshelo lwesokethi oluzixhasayo:Isebenzisa isakhiwo sokutywina i-interface yohlobo lwe-T, esisetyenziswa kwiimeko apho ukutyhala kokuhamba kwamanzi kwindawo egobileyo yombhobho kukhulu kakhulu, okanye indawo yokuhlala inkulu kakhulu, nto leyo ebangela ukuba i-interface iwele ngokulula. Xa kuthelekiswa ne-interface yohlobo lwe-T, i-welding ring, i-movable opening retaining ring, i-pressure flange ekhethekileyo kunye nee-connecting bolts ezifakwe kwi-spigot end ye-pipe zongezwa ukwenza i-interface ibe nokukwazi okungcono kokulwa nokutsala. I-retaining ring kunye ne-pressure flange zinokutyibilika, ukuze i-interface ibe nokukwazi ukukhulisa i-axial kunye nokuphambuka, okunokusetyenziswa xa i-pier ingenakubekwa.
3.Uqhagamshelo lweFlange:Ngokuqinisa iibholithi ezidibanisayo, iflange icinezela iringi yokutywina ukuze kufezekiswe ukutywinwa kwe-interface, okuyi-interface eqinileyo. Idla ngokuba njaloisetyenziswa kwiziganeko ezikhethekileyo ezifana noqhagamshelo lwezixhobo zeevalvu kunye noqhagamshelo lweepayipi ezahlukeneyos. Iingenelo zikuthembeka okuphezulu kunye nokutywinwa kakuhle. Ifanelekile kwiimeko apho ububanzi bombhobho bukhulu okanye ubude bombhobho bude, kwaye ikwafanelekile nakwiindawo apho uqhagamshelo lombhobho kunye neemfuno zokuwuqhaqha zixhaphake kakhulu. Nangona kunjalo, ukuba ugqunywe ngokuthe ngqo, kukho umngcipheko wokugqwala kwiibholiti, kwaye ukusebenza ngesandla kunempembelelo enkulu kwisiphumo sokutywinwa.
Amanyathelo athile: 1. Faka iiflanges kuzo zombini iziphelo zombhobho. 2. Yongeza i-gasket yokutywina phakathi kweeflanges ezimbini. 3. Bopha iflange ngeebholiti.
4. Ukuwelda kwe-arc:Iintonga zokuwelda ezifanelekileyo ezifana neentonga zokuwelda zeMG289 zinokukhethwa ukuze zisetyenziswe ukuwelda, kwaye amandla angaphezulu kunalawo enziwe ngentsimbi ephothiweyo. Xa usebenzisa i-arc hot welding, fudumeza kwangaphambili i-500-700℃ngaphambi kokuwelda; ukuba kukhethwe intonga yokuwelda ye-alloy esekelwe kwi-nickel ene-plasticity elungileyo kunye nokumelana nokuqhekeka okuphezulu, i-arc cold welding nayo ingasetyenziswa, enemveliso ephezulu, kodwa i-arc cold welding inesantya sokupholisa esikhawulezayo, kwaye i-weld ithambekele kwisakhiwo somlomo omhlophe kunye nokuqhekeka.
5. Ukuwelda ngegesi:Sebenzisa ucingo lokuwelda olufana ne-RZCQ, olufana nocingo lokuwelda olune-magnesium olune-ductile iron, sebenzisa ilangabi elingathathi hlangothi okanye ilangabi elibuthathaka le-carburizing, uze upholise kancinci emva kokuwelda.
Amanyathelo athile: 1. Coca isiphelo sombhobho. 2. Lungelelanisa isiphelo sombhobho kwaye udibanise. 3. Jonga umgangatho wombhobho.
6. Uqhagamshelo olunemisonto:Umbhobho wentsimbi othambileyo onemisonto kwelinye icala uqhagamshelwe kwijoyinti enemisonto efanayo.Ifanelekile ukusetyenziswa ngobubanzi obuncinci kunye noxinzelelo oluphantsi.Kulula ukuyifaka nokuyiqhaqha, kodwa ukusebenza kwayo kokutywina kulinganiselwe, kwaye ineemfuno eziphezulu zokuchaneka kokucubungula imisonto kunye nemisebenzi yokufakela.
Amanyathelo athile kwezinye iindlela zokudibanisa: 1. Qhuba imisonto yangaphandle ekupheleni kombhobho. 2. Sebenzisa izihlanganisi zemisonto yangaphakathi ukudibanisa. 3.Vala nge-sealant okanye i-tape eluhlaza.
7.Uqhagamshelo lwendandatho yokutywina elastiki: Faka iringi yokutywina elastiki ekupheleni kwecandelo ngalinye lombhobho, uze emva koko utyhale la macandelo mabini ombhobho uze uwadibanise kunye ngesixhumi sokutyhala. Iringi yokutywina iqinisekisa ukusebenza kokutywina koqhagamshelwano kunyeifanelekile kwiipayipi ezinobubanzi obuncinci.
8.Uqhagamshelo lwendandatho yephiko elingangeni manzi oluqinileyo:Shicilela indandatho yephiko lokumisa amanzi kumbhobho wesinyithi othambileyo, uze uyiphose ngqo ibe yinto enye ngexesha lokwakha iindonga zekhonkrithi eziqinisiweyo. Ihlala isetyenziselwa ukuqhagamshela imibhobho yesinyithi ethambileyo yokukhupha amanzi kunye neendonga ezifana nemithombo yokuhlola.
Ngamafutshane, indlela yokudibanisa imibhobho yesinyithi ethambileyo inokukhethwa ngokwemeko yokwakha. Ngokukodwa,uqhagamshelo lwesokethi lufanelekile kwiipayipi ezingaphantsi komhlaba, uqhagamshelo lweflange lufanelekile kwiimeko ezifuna ukuqhaqhwa rhoqo, uqhagamshelo olunemisonto lufanelekile kwiipayipi ezinobukhulu obuncinci, uqhagamshelo lwe-welding lufanelekile kwiindawo ezinoxinzelelo oluphezulu kunye nobushushu obuphezulu, kwaye uqhagamshelo loomatshini lufanelekile kwiimeko zexeshana okanye zengxakeko.
