Indlela Izixhobo zeValve ezenziwe ngokwezifiso ezixhasa ngayo imisebenzi yemihla ngemihla kwiShishini leeKhemikhali
Kwishishini leekhemikhali, apho imibhobho iphatha ii-asidi, ii-alkali, izinyibilikisi, kunye nomphunga oxinezelekileyo, ukusilela kwezixhobo akuyongxaki yokulungisa nje kuphela—ngumngcipheko wemveliso. Phakathi kwazo zonke izinto zoomatshini, iivalvu zezinye zezona zixhobo zithembeke kakhulu ekulawuleni ukuhamba kwenkqubo. Kodwa ngasemva kwevalvu nganye ethembekileyo kukho iseti yezinto ekufuneka zihlangabezane neemfuno zoomatshini nezekhemikhali ezifunekayo.
Asizizo iiValve Kuphela—Isizathu Sokuba Izinto Eziyinxalenye Zibalulekile
Ivalvu yekhemikhali ithembeke kuphela njengeendawo zayo. Imizimba yevalvu, iziqu, izihlalo, izibiyeli, kunye nee-couplings zichatshazelwa kukugqwala, ukuguguleka, ukujikeleza koxinzelelo, kunye nokutshintsha kobushushu imihla ngemihla. Xa isihlalo sevalvu singaphumeleli, kuyaqala ukuvuza. Ukuba isiqu siyabanjwa, ukusilela kwe-actuator kunokulandela. Yingakho amaqela olondolozo lwezityalo edla ngokucela izixhobo ezithile, ukufakwa, kunye neengubo zecandelo ngalinye levalvu.
Umzekelo, uninzi lwabathengi bethu beekhemikhali bafuna 316L okanye iHastelloy imizimba yevalvu ngenxa yokumelana kwayo nokugqwala. Kwiindawo zangaphakathi zokuhamba, njengesiqu sevalvu, intsimbi engagqwaliyo eqinileyo okanye i-AISI 420 egqunywe ngentsimbi idla ngokukhethwa. Kwiimeko ezirhabaxa, kwanebracket yevalvu kunye ne-actuator coupling kufuneka ziphuculwe zibe yintsimbi yekhabhoni egqunywe ngentsimbi okanye intsimbi engagqwaliyo ephindwe kabini.
Ukuziqhelanisa neemfuno zezityalo zeHlabathi lokwenyani
Uninzi lwezityalo zeekhemikhali azisebenzisi iinkqubo ezifanayo. Uyilo lwemibhobho lwahlukile, iimpawu ze-actuator zahlukile, kwaye iimfuno zokuhamba kwamanzi aziqhelekanga. Kule meko, izinto zevalvu ezenziwe ngokwezifiso aziyonto iphambili—ziyimfuneko.
Ifektri yethu idla ngokufumana imizobo ebonisa utshintsho oluncinci kwipateni yebholiti, ubude besiqu, okanye ubukhulu bomzimba. Olu tshintsho lusekelwe kumava entsimi, apho iinjineli zazi ukuba yintoni esebenze—okanye ehlulekileyo—kwixesha elidlulileyo. Endaweni yokubonelela ngezinto zekhathalogu eziqhelekileyo, sisebenzisana ngokusondeleyo namaqela olondolozo kunye neenjineli ze-OEM ukuhambisa oko bakudingayo ngokwenene.
Sihlala sibonelela:
- Izitulo zeevalvu ezenziwe ngomatshini ezilungelelaniswe nobubanzi obungengobuqhelekileyo bezibuko
- Imizimba yevalvu eyenziweyo enemilo ekhethekileyo ye-bore yemidiya ene-viscosity ephezulu
- Ii-valve couplings ezilungisiweyo ukuze zilingane phakathi kwee-actuators kunye nee-shafts ezijikelezayo
- Izibiyeli ezineendawo zomngxuma ochaseneyo ukuze zihambelane neefreyimu ze-actuator kwiindawo ezixineneyo
Apho Iinxalenye zeValve Zisetyenziswa khona kwiindawo zeekhemikhali
Kwisityalo esiqhelekileyo seekhemikhali, iivalvu kunye nezinto zazo zisetyenziswa kwi:
- Iinkqubo zokulinganisa i-asidi kunye nesiseko: izihlalo kunye neziqu ezimelana nokugqwala zibalulekile
- Ulawulo lokungena kunye nolwendawo yokuphuma kwe-Reactor: ii-flow ports ezenziwe ngokwezifiso kwiivalvu zebhola ziqinisekisa idosi echanekileyo
- Iinkqubo ze-CIP (ezicocekileyo endaweni): iivalvu ezisebenza ngokukhawuleza ezinee-glands zokupakisha ezinganyangekiyo kwiikhemikhali
- Ukunciphisa inkunkuma: iivalvu zoxinzelelo lomqolo ezisebenzisa izihlalo ze-PTFE kunye neziqu ezingama-304
- Imigca yokubuyisela isinyibilikisi: uyilo olukhuselekileyo emlilweni olunemizimba ye-A105 kunye nokulungiswa kobushushu obuphezulu
Kwanakwimigca yokusetyenziswa—njengomphunga, amanzi abandayo, kunye ne-nitrogen—ukuthembeka kweevalvu kuchaphazela ukhuseleko kunye nemveliso.
Utshintsho oluya ekuQinisekeni nasekuGcineni
Olunye utshintsho esilubonileyo kwiminyaka yakutshanje kukuhambela phambili kwindlela yoyilo lweevalvu ezigcinwa zisemgangathweni. Endaweni yokutshintsha iivalvu ezipheleleyo, izityalo ezininzi ngoku zigcina izinto ezibalulekileyo zeevalvu—iziqu, ii-couplings, izihlalo—ukuze zitshintshwe ngexesha lokungasebenzi elicwangcisiweyo.
Ivenkile yethu ye-CNC iyakuxhasa oku ngokulungisa ii-spare ukuze kuqinisekiswe kwaye kugcinwe iirekhodi zebhetshi ukuze kulungiswe ngokutsha. Kwizinto eziqhelekileyo ezifana nee-actuator couplings kunye nee-bracket mounts, sikwagrumba kwangaphambili ngokwe-ISO 5211, okwenza kube lula ukutshintsha nokuba loluphi uhlobo lwe-actuator.
Iingcinga Zokugqibela
Icandelo leekhemikhali livavanya iivalvu. Nangona ababoneleli abaninzi begxila kwiiyunithi zeevalvu ezipheleleyo, zezona zinto zincinci, ezihlala zingahoywayo ezimisela ukuthembeka kwexesha elide. Njengenkampani egxile kwizixhobo zeevalvu ezenziwe ngokwezifiso, asizisi nje kuphela iindawo—sixhasa ukusebenza kwentsimi.
Ukuba isityalo sakho sijongene neengxaki zokuguguleka okanye ukugcinwa kweevalvu ngokuphindaphindiweyo, isisombululo esingcono sisenokungabi yivalvu entsha—sisenokuba zizinto ezingcono.
