I-valves yebholazizinto ezixabisekileyo kwiinkqubo zokulawula ezilawulayo, ezinikezela intsebenziswano ethembekileyo kwimizi-mveliso eyahlukeneyo. Ukukhetha phakathi kobhedu kunye ne-valve yentsimbi engenasitayile, nangona kunjalo, inokuba ngumceli mngeni. Izinto zonke zizisa iipropathi kunye nezibonelelo zetafile, zenza ukuba kubalulekile ukuqonda ukungafani kwabo ngokweenkcukacha. Esi sikhokelo sibanzi, siya kuhlalutya ezinye iindlela zokukhetha ukuba wenze isigqibo esifanelekileyo sesicelo sakho.
1. Ubume bezinto ezibonakalayo kunye neepropathi
I-Brass Ball Valves
UBrass yi-Alloper yobhedu kunye ne-zinc, ngexabiso lezinye izinyithi njengokukhokela ukuphucula ubisi. Iimpawu zayo eziphambili zibandakanya:
Ukungalungisi:Ifakwe ngokulula kwaye idityanisiwe, yenza ivala ye-brass ixabisa indleko zokuvelisa.
Ukungaxhathisi ubuchule:Ukunganyangeki kukungqubana nokunyanzelwa kwiindawo ezingathathi hlangothi.
Ukuqhutywa kwe-hormal:Ukuqhutywa kobushushu obufanelekileyo, kufanelekile kwiinkqubo ezinemfuno zobushushu eziphakathi.
I-valves yentsimbi engenalo
Intsimbi engenasimo yi-alloy ikakhulu iqulathe intsimbi, iChromium, kunye neNickel. Ipropathi yayo eyahlukileyo ibandakanya:
Amandla aphezulu:Ikwazi ukucinezelwa kakhulu kunye noxinzelelo lomatshini.
• Ukuxhathisa okungaqhelekanga:I-Chromium yenza umaleko obonakalayo kumphezulu, ukukhusela ngokuchasene ne-oxidation kunye nokuhlaselwa kwemichiza.
• Ukunyamezelana kobushushu:Isebenza ngokufanelekileyo kuluhlu lwamaqondo obushushu ngokubanzi.
I-2. Ukunganyangeki kwe-Corrosion: Thelekisa iinkcukacha
Ukuchasana ne-Corrosion yenye yezona zinto ziphambili ekufuneka ziqwalaselwe xa ukhetha izinto ze-valve zebhola.
Ubhedu:I-brass ichasa i-corosion kumanzi amatsha kunye neendawo ezinobulali. Nangona kunjalo, ichaphazeleka ukuba i-dezinistition, inkqubo apho i-zinc le dolophana ivele phantsi kwe-acidic ixesha elide okanye izinto zeAlkaline, zenza buthathaka umbandela. Ubhedu lukwangacetyiswa ukuba lusetyenziswe ngamanzi olwandle okanye ngeendlela ezityebileyo ze-chlorine.
• Yenziwe ngentsimbi eshayinayo:Intsimbi engenasibala, ngakumbi amabakala afana ne-304 ne-236, inika ukumelana nokuchasana nokuziphatha, kwanakwindawo ezinobundlobongela. Chwetheza intsimbi ye-316 ye-Stainess, inesibindi kunye ne-molybdenum, inikezela ukhuseleko olwaphuculweyo kwi-chloride pide lokubetha kwaye ilungele ukusetyenziswa kwaselwandle.
Ivalve yentsimbi engenalo
3. Amandla, ukuqina, kunye nobomi obude
Amandla kunye nokuqina ukumisela amandla evalini okwenza phantsi koxinzelelo.
Iivalva zeBhola yeBhola:Iivila zobhedu zihlala ziqinile ngokwaneleyo kwizicelo zemihla ngemihla kodwa zinokuphelisa uxinzelelo oluphezulu okanye iimeko zobushushu obuphezulu. Ngelixa ixesha elide elihlala lingapheliyo kwiindawo ezingenamagqabi, ixesha labo lakwabomi liyancipha ngendlela yoburhasi.
• I-valves yentsimbi engenasitayile:I-stain zentsimbi ezingenantsingiselo zigqithisile, ukugcina ingqibelelo phantsi koxinzelelo olukhulu, ubushushu kunye noxinzelelo loomatshini. Oku kubangela ukuba balungele imisebenzi yezommiselo nemfuno ephezulu, apho ukuthembeka kubalulekile.
I-4. Ubushushu kunye noxinzelelo lokuphatha
Iimeko zokusebenza zomsebenzi zenkqubo yakho zidlala indima ebaluleke kakhulu ekukhetheni izinto ezibonakalayo.
Ubhedu:I-valve yebhola ye-bloss i-valves emsebenzini isebenze kakuhle kwiinkqubo ezinamaqondo obushushu ukuya kuthi ga kwi-200 ° F (93 ° C) kunye noxinzelelo malunga ne-300 PSI. Zilungele kakuhle iinkqubo zokuhlala kunye neenkqubo zokukhanya kwezamashishini.
• Yenziwe ngentsimbi eshayinayo:I-valves yentsimbi engenasitali inokujongana neemeko ezigqithisileyo, kunye namaqondo obume kwiqondo lobushushu elingaphezulu kwe-400 ° F (204 ° C) kunye noxinzelelo olugqithisileyo kwi-1 000 psi. Zenzelwe ukutya iindawo ezinje ngeenkqubo ze-Steam, ukuqhubekisa kwamachiza, kunye nemibhobho yoxinzelelo oluphezulu.
I-5.Intervial noorhulumente kunye nezokhuseleko
Ubhedu:Iqulethe izixa-mali zokukhokela, ezinokuthi ziyeke ngamanzi okusela ukuba azifakwanga kakuhle okanye zidityanisiwe. Iinketho zobhedu ezifumanekayo ezifumanekayo ziyafumaneka ukuze zihambelane nemigangatho yokhuseleko lokusela amanzi, njengalawo achazwe kuMthetho wamanzi oKhuselekileyo wase-US.
• Yenziwe ngentsimbi eshayinayo:I-Coum-free-ayinatyhefu, intsimbi engenabungozi kukhethwa izicelo ezibandakanya amanzi okusela, amayeza, kunye nemveliso yokutya. Ukongeza, kuya kuphi shunga kwakhona, kuyenza ukhetho olunobuhlobo olunobuhlobo.
Iimfuneko zokuFunda
Ubhedu:Iivasta zobhedu zifuna ulondolozo oluncinci kwiindawo ezinobulali. Nangona kunjalo, kwiimeko zoncedo, uvavanyo rhoqo luyafuneka ukuze ufumane iimpawu zokuqala zokuphendulela.
• Yenziwe ngentsimbi eshayinayo:I-valves yentsimbi engenasitali ziseto-iphantsi kwaye igcine inkangeleko yayo kunye nokusebenza kwexesha, nkqu nakwimeko ezinzima. Ukucocwa kwesiqhelo kunokufuneka kwiindawo ezingcolisekileyo ezingcolisekileyo ukugcina ukusebenza kakuhle.
I-7. Izinto zokuqaphela xa ukhetha
Ukwenza ukhetho olufanelekileyo, vavanya ezi zinto:
Imeko yokusebenza:Vavanya amaqondo obushushu, uxinzelelo, kunye nokuvezwa kwezinto ezibonakalayo.
• Izithintelo zohlahlo-lwabiwo mali:Ibhalansi ephezulu yeendleko ezinokugcina ixesha elide.
• Iimfuno zesicelo:Tshatisa iipropathi zezinto ezibonakalayo kwiimfuno ezithile zenkqubo.
Ukuthobela umthetho:Ukuqinisekiswa kokuhambelana kwemigangatho yeshishini yokhuseleko kunye nokusebenza.
Ukuqukumbela
Ukukhetha indawo efanelekileyo ye-valve ye-velic-brass okanye intsimbi engenasimo-ifuna uhlalutyo ngononophelo kwiimfuno zakho zesicelo.I-Brass Ball ValvesNikeza isisombululo esinexabiso leemeko eziphakathi, ukukhululeka kwiNdawo yokuhlala kunye noSeto oluNjineli.I-valves yentsimbi engenaloKwelinye icala, kukuzikhethela iindawo ezifuna amandla apho amandla apho amandla, ukumelana nokuziphatha okuhle, kunye nobomi obude bube yinto enkulu.
Ngokuqonda iipropathi ezizodwa kunye nezibonelelo zezinto nganye, unokwenza isigqibo esiqinisekisiweyo esiqinisekisa ukusebenza ngokufanelekileyo, ukhuseleko, kunye nokusebenza kwexabiso leprojekthi yakho. Nokuba yeyokwenkqubo ye-plumbang ye-plumbang okanye umbhobho weekhemikhali zemveliso, izixhobo ze-velic ze-veli ze-veli ze-valve zinokwenza wonke umahluko.
