Nansi eminye imikhiqizo ongakhetha kuyo
1. Kungani kukhona ukuqhekeka kwe-flange ngemuva kokushisela
Ekukhiqizeni imishini yesitsha, lapho i-flange yensimbi engagqwali kanye nesilinda zishiselwe, kuzoba nemifantu entanyeni ye-flange, hhayi kumthungo wokushisela.Kwenzenjani?Kungani kunesimo esinjalo?Okokuqala, ake sihlaziye izizathu zokuqhekeka okushisayo.
Imifantu eshisayo imifantu ekhiqizwa esigabeni sokushisa okuphezulu ngesikhathi senqubo yokupholisa ye-weld, ikakhulukazi ensimbi yokushisela, kanye nenani elincane endaweni eseduze yomthungo.Ingahlukaniswa ngokuqhekeka kwe-crystallization (solidification), imifantu ye-liquefaction kanye nemifantu ye-polygonal.Imifantu ye-crystalline iwuhlobo oluvame kakhulu, ikakhulukazi ekushiseleni kwezinsimbi zekhabhoni eziqukethe izinto ezingcolile (S, P, Si kanye no-C), izinsimbi ezingenasici zesigaba esisodwa se-austenitic, i-aluminium nama-alloys ayo nezinye izakhiwo ezishiselwe.Izici eziyinhloko ezinomthelela ukucindezelwa kwe-welding, indawo encibilikayo ephansi ye-eutectic (ukwakheka kwamakhemikhali ensimbi eshiselwe), izinga lokushisa ngokweqile kwejoyinti elishiselwe (inqubo).
2.Ungawagwema kanjani ama-Hot Cracks
Uma sibheka izithombe, i-304 stainless steel ine-plasticity eqinile.Uma kuyi-flange eyenziwe ngomgunyathi, izidingo zenqubo yokushisela zikhululekile, futhi imifantu ngokuvamile ayibangelwa.Uma kuwukulingisa, lesi simo sijwayele ukwenzeka.Ngakho-ke, ekusebenzeni, sigwema kanjani imifantu emsebenzini?Izinyathelo zokunciphisa ukuthambekela kokuqhekeka okushisayo zifaka:
1) Nciphisa okuqukethwe kwezinto ezingcolile ezifana no-S no-P endabeni.
2) Ukwenyusa ngokufanele isilinganiso se-Mn/S kungangena esikhundleni se-Fe ye-Fe-FeS encibilika kancane eutectic yakhe i-MnS enephuzu lokuncibilika elingu-1620Co, ngaleyo ndlela kuthuthukiswe ukumelana nokuqhekeka kwe-weld.
WC=0.10~0.12%, WMn=2.5% ngaphambi kokuthi isebenze
I-WC=0.13~0.20%, i-WMn=1.8% noma ngaphansi iyasebenza
WC=0.21~0.23%, ithonya elizuzisayo le-WMn lincane.
3) Sebenzisa izindlela zokushisela ezifanele kanye nezinqubo zokulawula ukufakwa kwamandla kalayini nokunciphisa ukushisisa kwe-weld.
4) Engeza i-Ti, i-Mo, i-Nb noma izakhi zomhlaba ezingavamile ekushiseleni ukuze uvimbele ukuthuthukiswa kwezinhlamvu zekholomu, ucwenge okusanhlamvu, futhi uthuthukise ngokuphawulekayo ukusebenza.
I-DIN SANITARY BUTTERFLY VALVE UCHUPHU LUPHELA NGESIBAMBA ESINEMIBUZO ENINGI
I-valve yebhola ye-Sanitaryiphucuziwe ngaphakathi nangaphandle.Iziphetho ze-clamp zivumela ukuqaqa kalula ukuhlanza, ukulungisa noma ukufaka izingxenye esikhundleni uma kudingeka.
I-valve yebhola ye-Sanitarynge-actuator isetshenziswa ekucubunguleni ukudla nesiphuzo, ukuphisa, ukuhluza uwoyela, izimonyo, izimboni zemithi, kanye nezimboni zamakhemikhali ukulawula ukugeleza okuphakathi.
I-valve yebhola ye-Sanitary ipholishwa ngaphakathi nangaphandle.
Iziphetho ze-clamp zivumela ukuqaqa kalula ukuhlanza, ukulungisa noma ukufaka izingxenye esikhundleni uma kudingeka.
I-Disc yenziwe ngomshini ngokugcwele futhi iphucuziwe
Ukukhweza kalula kwama-actuator kagesi noma we-pneumatic anezinga lemboni elijwayelekile le-ISO5211 iphedi yokukhweza eqondile.
Zonke izinto zokwakha zihambisana ne-FDA, USDA kanye nezidingo ze-3-A
I-SMS SANITARY BUTTERFLY VALVE WELDING EPHELA NGE-PULL HANDLE
●Umzimba nediski ye-Sanitary butterfly valvezakhiwe ngokunemba okuphezulu kwe-CNC lathe processing.
● Ama-valve uvemvane ahlangene, alula, futhi asebenzisa ukwakheka okulula okunezakhi ezimbalwa kuphela.
● Ukusebenzisa ivalve uvemvane kulula futhi kulula;
● Idiski idinga kuphela ukuzungezisa okungu-90° ukuze ikwazi ukuvula nokuvala ngokushesha futhi inikeze izici ezithembekile zokulawula uketshezi.
● I-Sanitary butterfly valve inezinhlobo ezimbili zezimvu—i-ballistic seal kanye ne-metal seal.
● Ivalvu enwebekayo yokuvala ingashumeka emzimbeni wevalvu noma ixhunywe kudiski nxazonke.
I-SMS SANITARY BUTTERFLY VALVE UCHUCHU LUPHELA NGESIBAMBA ESINEMIBUZO ENINGI
Iuvemvane valveyakhelwe ukucubungula ukudla nesiphuzo, imikhiqizo yamakhemikhali, izicelo zoketshezi lwezimboni.
I-Disc yenziwe ngomshini ngokugcwele futhi iphucuziwe
100% ihloliwe
Insimbi engagqwali sanitary butterfly valvesingavulwa ngokuzenzakalelayo nge-actuator noma ngesandla ngesibambo.
Isibambo sivimba amavalvu ovemvane ahlanzekile endaweni "evulekile" noma "evaliwe", ngokuqinisekile kukhona enye indawo etholakalayo.
I-actuator iphusha i-piston ye-axial movement ibe yi-90 degree ukuze ilawule ama-valve uvemvane lokukhucululwa kwendle.
I-DN25 SANITARY BUTTERFLY VALVE CLAMP END
Umzimba kanye ne-disc ye-Sanitary butterfly valvezakhiwe ngokunemba okuphezulu kwe-CNC lathe processing.
Ama-valve evemvane ahlanzekilezihlangene, azisindi, futhi zisebenzisa ukwakheka okulula okunezingxenye ezimbalwa kuphela.
Ukusebenzisa i-valve butterfly kulula futhi kulula;idiski idinga kuphela ukuzungezisa u-90° ukuze ikwazi ukuvula nokuvala ngokushesha futhi inikeze izici ezithembekile zokulawula uketshezi.
I-valve ye-butterfly ye-pneumatic yezempilo kufanele igcine indawo evulekile ngokugcwele, ubukhulu be-disc buhlinzeka ngokugeleza okuphakathi emzimbeni we-valve, ngakho-ke ukwehla kokucindezela okubangelwa i-valve encane kunezici ezinhle zokulawula ukugeleza.
ISanitary butterfly valveinezinhlobo ezimbili zezimpawu - uphawu lwe-ballistic kanye nophawu lwensimbi.I-valve ye-elastic seal ingafakwa emzimbeni we-valve noma ifakwe ku-disc nxazonke.
