Inqaku eliza kukwazisa ngaloIivalvu zebhola zePVC
Umsebenzi wevalvu yebhola yePVC
Ivalvu yebhola, inxalenye yokuvula nokuvala (ibhola) iqhutywa sisiqu sevalvu kwaye ijikeleza i-axis yesiqu sevalvu. Isetyenziselwa ikakhulu ukusika okanye ukudibanisa i-medium kwipayipi. Ikwasetyenziselwa ukulawula ulwelo kunye nolawulo. Phakathi kwazo, ivalvu yebhola enomfanekiso we-V oqinileyo inamandla okucheba aqinileyo phakathi kwesiseko esinomfanekiso we-V kunye nesihlalo sevalvu yesinyithi se-carbide efakwe isamente. Amandla okucheba afaneleke ngakumbi kwimidiya equlethe imicu kunye namaqhekeza amancinci aqinileyo.
Ivalvu yebhola eneendlela ezininzi kumbhobho ayinakulawula kuphela ngokuguquguqukayo ukudibana, ukuphambuka kunye nokutshintsha kwendlela yokuhamba kwesixhobo, kodwa inokuvala nayiphi na itshaneli enye ukuze idibanise ezinye itshaneli ezimbini. Le valve ngokubanzi kufuneka ifakwe ngokuthe tye kumbhobho.
Udidi lweevalvu zebhola: ivalvu yebhola yomoya, ivalvu yebhola yombane, ivalvu yebhola yesandla.
Ulwazi oluSisiseko
Ukusetyenziswa kwevalvu yebhola ye-pvc ngokubanzi akudluli kwi-45 ℃, kwaye le medium ayifanelekanga kwizinyibilikisi ze-organic kunye nee-oxidants ezinamandla. Ngokwemeko le, olu hlobo lwevalvu yebhola lunokusetyenziswa kuphela kulwelo olungaphantsi kwe-45°C kwaye uxinzelelo lungaphantsi kwe-1.0mpa.
Xa kuthelekiswa nezinye iivalvu, inezi nzuzo zilandelayo.
1. Ukumelana nolwelo oluphantsi
Ivalvu yebhola inomlinganiselo omncinci wokumelana nolwelo kuzo zonke iivalvu. Kwanevalvu yebhola enobubanzi obuphantsi inomlinganiselo omncinci wokumelana nolwelo. Ivalvu yebhola yePVC yimveliso entsha yevalvu yebhola eyenziwe ngokweemfuno zemibhobho eyahlukeneyo yolwelo olubolayo. Iingenelo zemveliso: ubunzima obulula, ukumelana nokugqwala okunamandla, inkangeleko encinci nentle, ubunzima bomzimba obulula, ukufakwa okulula, ukumelana nokugqwala okunamandla, uluhlu olubanzi lokusetyenziswa, izixhobo ezicocekileyo nezingenatyhefu, ezinganyangekiyo, ezilula ukuziqhekeza, ukulungiswa okulula.
Ukongeza kwizixhobo zeplastiki zePVC, iivalvu zebhola zeplastiki ziquka iPPR, iPVDF, iPPH, iCPVC, njl.
2. Ivalvu yebhola yePVCinokumelana nokugqwala okugqwesileyo.
Indandatho yokutywina isebenzisa i-F4. Imelana kakuhle nokugqwala kwaye yandisa ubomi benkonzo. Ukujikeleza okuguquguqukayo kwaye kulula ukuyisebenzisa.
3. Njengevalvu yebhola edibeneyo,Ivalvu yebhola yePVCInendawo ezimbalwa zokuvuza, inamandla aphezulu, kwaye ivalvu yebhola yohlobo loqhagamshelo kulula ukuyihlanganisa nokuyiqhaqha.
Ukufakelwa nokusetyenziswa kwevalvu yebhola: Xa iiflanges kuzo zombini iziphelo ziqhagamshelwe nombhobho, iibholithi maziqiniswe ngokulinganayo ukuthintela iflange ukuba ingaguquki kwaye ibangele ukuvuza. Jika isiphatho ngokwewotshi ukuze sivale, kwaye ngokuphambeneyo ukuze sivuleke. Ingasetyenziswa kuphela xa kunqunyulwa kwaye kuphuphuma, kwaye ukulungiswa kokuhamba kwamanzi akufanelekanga. Ulwelo oluneziqwenga eziqinileyo lunokukrwela lula umphezulu webhola.
4. Imisebenzi enamandla:
Uhlobo olukrelekrele, uhlobo olulinganayo kunye nohlobo lokutshintsha zonke ziyafumaneka, kwaye umthamo umncinci: umthamo ulingana kuphela ne-35% yeemveliso ezifanayo.
5. Abantu abalula nabangabizi kakhulu:
Ubunzima bumalunga ne-30% kuphela yeemveliso ezifanayo, kwaye ukusebenza kwayo kuthembekile: iibheringi kunye nezinto zombane ziimveliso ezidumileyo ezingenisiweyo.
6. Umhle kwaye unesisa:
Igobolondo eliyi-aluminium alloy die-casting, elithambileyo neligudileyo, elinamandla aphezulu kunye nokumelana nokuguguleka: izixhobo ezikhethekileyo ze-copper alloy ezenziwe nge-worm, elinamandla aphezulu kunye nokumelana nokuguguleka okuhle.
7. Isiqinisekiso sokhuseleko:
I-voltage yokumelana ne-1500v, i-wire lock ekhethekileyo yentambo yokutshixa ilula: umbane wesigaba esinye, i-wire yangaphandle ilula kakhulu.
8. Kulula ukuyisebenzisa:
Ukuhlolwa kweendawo ezingenayo ioyile, ukungangeni manzi kunye nokungagqwali, ukufakwa kuyo nayiphi na i-engile, isixhobo sokukhusela: umda ophindwe kabini, ukhuseleko lobushushu obugqithisileyo, ukhuseleko lokugqithisa.
9. Izantya ezininzi:
Ixesha lilonke lokuhamba yimizuzwana emi-5 ukuya kwengama-60, nto leyo enokuhlangabezana neemfuno zeemeko ezahlukeneyo zokusebenza. Intambo yodidi olukhethekileyo yenziwe ngentambo engatshisi ubushushu kwaye ethintela umlilo, engagugiyo xa ifudunyezwa, kwaye ikhuselekile kwaye ithembekile.

Zithini izakhono zokugcinwa kwevalvu yebhola ye-PVC
★ Ukuba ivalvu yebhola iyavuza ngenxa yesiphatho esikhululekileyo, cinezela isiphatho nge-vise, uze ujike isiphatho ngendlela echasene newotshi ukuze usiqinise. Kufuneka kuqatshelwe ukuba kufuneka ulumke xa uqinisa isiphatho, ungasebenzisi amandla amaninzi, kungenjalo ivalvu yebhola iya konakala lula.
★ Ukuba unxibelelwano phakathi kwevalvu yebhola ye-pvc nombhobho wamanzi aluqinanga, ukuvalwa akulunganga, kwaye kukho ukuvuza kwamanzi, ungayisonga ivalvu yeteyiphu yezinto eziluhlaza kwindawo apho umbhobho wamanzi udibanisa khona ibhola, kwaye ufake ivalvu yebhola emva kokuyijika ukuze uphephe ukuvuza kwamanzi.
★ Ukuba kukho ukuvuza kwamanzi ngenxa yokuqhekeka okanye isiphene sevalvu yebhola, ivalvu yebhola endala kufuneka ikhutshwe ize ifakwe kwakhona.
Kufuneka kuqatshelwe ukuba ivalvu yebhola ye-pvc kufuneka isetyenziswe ngokuchanekileyo xa iqhaqhwa kwaye ihlanganiswa, kwaye la manqaku alandelayo kufuneka enziwe kakuhle.
★ Emva kokuba ivalvu yebhola ivaliwe, lonke uxinzelelo olukwivalvu yebhola kufuneka lukhutshwe ngaphambi kokuba iqhaqhwe, kungenjalo ingozi inokubakho. Abantu abaninzi abayinaki le nto. Yiqhaqhe kwangoko emva kokuba ivalvu ivaliwe. Kusekho uxinzelelo apho. Le nxalenye yoxinzelelo ayikhululwa, nto leyo engayi kunceda ukhuseleko lomntu.
★ Emva kokuba ivalvu yebhola isusiwe kwaye ilungisiwe, kufuneka ifakwe kwicala elichaseneyo lokuyisusa kwaye iqiniswe, kungenjalo iya kuvuza.
Ukuba ufuna ivalvu yebhola ye-pvc ihlale ixesha elide, kufuneka unciphise inani leeswitshi kangangoko unako. Xa kukho ukuvuza kwamanzi, kufuneka uyilungise ngexesha ngokweengcebiso ezintathu ezikwinqaku, kwaye ubuyele ekusebenziseni okuqhelekileyo ngokukhawuleza.
