Indawo yokuvala yamavalvu wensimbi (I-DC341X-16 Ivalvu ye-butterfly ehlukileko enamafletjhi amabili) ngokuvamileko yenziwa ngu (Ivalvu ye-TWS)ukuwelda. Iinsetjenziswa ezisetjenziselwa ukufaka ivalvu zihlukaniswe zaba ziinkoro ezi-4 ezikulu ngokuya ngomhlobo we-alloy, okutjho ama-alloy asekelwe ku-cobalt, ama-alloy asekelwe ku-nickel, ama-alloy asekelwe ku-iron, kanye nama-alloy asekelwe ku-copper. Iinsetjenziswa ze-alloy zenziwa zibe ma-electrode, iintambo zokuwelda (okufaka hlangana iintambo ezine-flux-cored), ama-flux (okufaka hlangana ama-transition alloy fluxes) kanye namapuyere we-alloy, njll., begodu zivezwa ngokusebenzisa i-arc welding ngesandla, i-oxyacetylene flame welding, i-tungsten argon arc welding, i-sumerged arc automatic welding kanye ne-arc welding ye-arc.
Ukukhethwa kwezinto zokuvala ivalvu (DC341X3-10Ivalvu yevithamini enamafletjhi amabiliindandatho yokuvala umzimba) ngokuvamileko isekelwe emazingeni womtjhiso wokusetjenziswa, umfutho wokusebenza nokugqwala kwevalvu, nofana umhlobo wevalvu, isakhiwo sendawo yokuvala, umfutho othileko wokuvala kanye nomfutho othileko ovunyelweko, nofana ubujamo bokukhiqiza nokukhiqiza bebhizinisi, amandla wokusebenza wemitjhini kanye nekghono lobuchwepheshe lokusebenza kanye neemfuneko zabasebenzisi. Idizayini ehlelekileko kufanele yamukelwe, begodu izinto zokuvala ezinemali ephasi, ikambiso yokukhiqiza elula nokusebenza kuhle kokukhiqiza kufanele zikhethwe ngaphasi kobujamo bokwanelisa ukusebenza kwe- (D341X3-16 I-valv ye-butterfly concentric eneenqhema ezimbilie )valve.
Ezinye zezinto ezisetjenziselwa ukuvala iindawo zokuvala ivalvu zinefomu elilodwa kwaphela, nofana i-electrode nofana intambo yokuwelda nofana ipuyere ye-alloy, njeke indlela yinye yokuvala ingasetjenziswa. Ezinye zenziwa zibe ziintonga zokuwelda, iintambo zokuwelda nofana amapuyere we-alloy ngeendlela ezihlukahlukeneko, njenge-stellite l 6 alloy, zombili iintonga zokuwelda (D802), iintambo zokuwelda (HS111) kanye namapuyere we-alloy (PT2102), bese kuthi i-manual arc welding, i-oxy2acetylene flame welding, i-tungsten argon, i-argon arc welding we-plasma arc welding ukutjheja nezinye iindlela zingasetjenziselwa ukutjheja phezulu. Lokha nasikhetha izinto zokuvala ivalvu, kufuze sicabangele ukukhethwa kwendlela yokuvala ngethekhnoloji evuthiweko, ikambiso elula nokusebenza kuhle kokukhiqiza okuphezulu kwebhizinisi, ukwenzela ukuqinisekisa ukufezeka kokusebenza kwayo ekukhiqizeni ukuvala indawo.
Indawo yokuvala yingcenye eqakathekileko yevalvu (I-D371X-10 I-wafer butterfly valve), begodu ikhwalithi yayo ithinta ngqo ipilo yesevisi yevalvu. Ukukhetha okuzwakalako kwezinto zokuvala ivalvu kungenye yeendlela eziqakathekileko zokwenza ngcono ipilo yevalvu. Ukungazwisisani kufanele kugwenywe ekukhethweni kwezinto zokuvala ivalvu.
Inganekwane 1: Ubudisi bevalvu (D371X3-16C) ukuvala indawo ephezulu, begodu ukujamelana kwayo nokuguga kuhle.
Iimhloliso zitjengisa bona ukujamelana nokuguga kwepahla yokuvala ivalvu kunqunywa yisakhiwo esincani sepahla yensimbi. Ezinye izinto zensimbi ezine-austenite njenge-matrix kanye nesakhiwo esincani sesigaba esiqinileko aziqinile khulu, kodwana ukujamelana nokuguga kwazo kuhle khulu. Indawo yokuvala yevalvu inokuqina okuthileko okuphezulu ukugwema ukulimala nokuklwebheka ziimvuthuluka eziqinileko phakathi. Nakuqalwa zoke izinto, inani lobunzima HRC35~45 liyafaneleka.
Inganekwane 2: Intengo yepahla yokuvala ivalvu iphezulu, begodu ukusebenza kwayo kuhle.
Intengo yezinto eziphathekako ziyimpawu yazo, kuthi ukusebenza kwezinto zibe yinto ebonakalako, begodu akukho ubudlelwano obutlhogekako hlangana nalokhu kokubili. Insimbi ye-cobalt ema-alloy asekelwe e-cobalt ivela eendaweni ezibuya ngaphandle, begodu intengo iphezulu, njeke intengo yezinto ezisekelwe e-cobalt iphezulu. Iinhlanganisela ezisekelwe ku-cobalt zibonakala ngokujamelana nokuguga okuhle emazingeni womtjhiso aphezulu, kuthi lokha nazisetjenziswa emazingeni womtjhiso ajayelekileko naphakathi, intengo/ukusebenza kuphezulu. Ekukhetheni izinto zokuvala ivalvu, izinto ezineentengo eziphasi/ukusebenza kufanele zikhethwe.
Inganekwane 3: Nangabe into yokuvala yevalvu inokujamelana nokugqwala okuhle endaweni eqinileko yokugqwala, kufanele ivumelane nezinye iinsetjenziswa ezigqwalako.
Ukujamelana nokugqwala kwezinto zensimbi kunendlela yayo eyinkimbinkimbi, into inokujamelana nokugqwala okuhle endaweni enamandla yokubola, begodu ubujamo butjhuguluka kancani, njengezinga lokutjhisa nofana ukugxila kwendawo, ukujamelana nokugqwala kuyatjhuguluka. Kwenye indlela yokugqwala, ukujamelana nokugqwala kuyahluka khulu. Ukujamelana nokugqwala kwezinto zensimbi kungaziwa kwaphela ngokuhlola, begodu ubujamo obufaneleko kufuze buzwisiswe ukobana busetjenziswe eentweni ezifaneleko, begodu akukafaneli bona bubolekwe ngokungaboni.
