Indatshana yokukwazisa ngamavalvu ebhola e-PVC
Umsebenzi we-valve we-PVC webhola
I-valve yebhola, i-valve lapho ingxenye yokuvula nokuvala (ibhola) iqhutshwa yi-valve stem futhi izungeza i-axis ye-valve stem.Ngokuyinhloko isetshenziselwa ukusika noma ukuxhuma okuphakathi epayipini.Ingasetshenziselwa ukulungisa nokulawula uketshezi.Phakathi kwazo, i-valve yebhola eqinile efana ne-V ine-shear eqinile phakathi kwe-core efana ne-V kanye nesihlalo sensimbi se-alloy eqinile.Amandla okugunda afaneleka ngokukhethekile imidiya equkethe imicu kanye nezinhlayiya ezincane eziqinile.
I-valve yebhola enezindlela eziningi ephayiphini ayikwazi nje kuphela ukulawula ngokuguquguqukayo ukuhlangana, ukwehlukana, nokushintshwa kwendlela yokugeleza kwendawo ephakathi nendawo, kodwa futhi ivala noma isiphi isiteshi ukuxhuma amanye amashaneli amabili.Lolu hlobo lwe-valve ngokuvamile kufanele lufakwe ngokuvundlile epayipini.
Ukuhlukaniswa kwe-valve yebhola: i-valve yebhola ye-pneumatic, i-valve yebhola kagesi, i-valve yebhola yezandla.
Ulwazi Oluyisisekelo
Ngokuvamile, ukusetshenziswa kwepvc ibhola valveakufanele idlule ku-45 ℃, kanti i-medium ayifanele izinyibilikisi eziphilayo kanye nama-oxidants aqinile.Ngokwalesi simo, lolu hlobo lwe-valve yebhola luvinjelwe ukusebenzisa uketshezi olungaphansi kuka-45 ° C futhi ingcindezi ingaphansi kwe-1.0mpa.
Uma iqhathaniswa namanye ama-valve, inezinzuzo ezilandelayo.
1. Ukumelana noketshezi oluphansi
I-valve yebhola iyona enokumelana okuncane kakhulu noketshezi phakathi kwawo wonke ama-valve, ngisho ne-diameter ye-diameter encishisiwe, ukumelana kwayo noketshezi kuncane kakhulu.Ivalvu yebhola ye-PVC iwumkhiqizo omusha wevalvu webhola othuthukiswe ngokwezidingo zoketshezi oluhlukahlukene lwamaphayiphi okudlayo.Izinzuzo zomkhiqizo: isisindo esilula, ukumelana nokugqwala okuqinile, ukubukeka okuhlangene nokuhle, isisindo esincane nokufakwa kalula komzimba, ukumelana nokugqwala okuqinile, uhla olubanzi lwezicelo, izinto ezihlanzekile nezingezona ubuthi, ukumelana nokugqokwa, ukuqaqa kalula, ukulungiswa okulula .
Ngokungeziwe ezintweni zepulasitiki ze-PVC, ama-valve ebhola epulasitiki ahlanganisa i-PPR, i-PVDF, i-PPH, i-CPVC, njll.
2. I-valve yebhola ye-PVC inokumelana nokugqwala okuhle kakhulu.
Indandatho yokuvala ithatha i-F4.Ukumelana nokugqwala okuhle kakhulu nokwelula impilo yesevisi.Ukujikeleza okuguquguqukayo futhi kulula ukuyisebenzisa.
3. Njenge-valve yebhola ebalulekile, i-valve yebhola ye-PVC inamaphuzu ambalwa okuvuza, amandla aphezulu, futhi i-valve yohlobo lokuxhuma kulula ukuhlanganisa nokuhlakazwa.
Ukufakwa kanye nokusetshenziswa kwe-valve yebhola: Uma ama-flange emikhawulweni yomibili exhunywe nepayipi, amabhawodi kufanele aqiniswe ngokulinganayo ukuze kuvinjwe i-flange ukuthi ingakhubazeki futhi ibangele ukuvuza.Vula isibambo ngokwewashi ukuze uvale, futhi ngokuphambene nalokho ukuze uvule.Ingasetshenziselwa kuphela ukusika nokugeleza, futhi ukulungiswa kokugeleza akufanelekile.Uketshezi oluqukethe izinhlayiya eziqinile lunganwaya kalula ingaphezulu lebhola.
4.Ukusebenza okuqinile:
Uhlobo oluhlakaniphile, uhlobo lokulinganisa, shintsha uhlobo lwento yonke, usayizi omncane: ivolumu ilingana kuphela nama-35% wemikhiqizo efanayo.
5.Abantu abalula nabashibhile:
Isisindo singama-30% kuphela wemikhiqizo efanayo, futhi ukusebenza kunokwethenjelwa: ama-bearings kanye nezingxenye zikagesi zamukela imikhiqizo edumile evela kwamanye amazwe.
6.Muhle futhi uyaphana:
Igobolondo le-Aluminium alloy die-casting, elihle futhi elibushelelezi, amandla aphezulu nokumelana nokugqokwa: isondo elikhethekile lengxube yethusi elibunjiwe lezikelemu, amandla aphezulu, ukumelana nokugqokwa okuhle.
7.Isiqinisekiso sokuphepha:
I-1500v ukumelana ne-voltage, i-wire lock ekhethekile yokukhiya umugqa wekhebula ilula: ukunikezwa kwamandla kwesigaba esisodwa, izintambo zangaphandle zilula ngokukhethekile.
8.Kulula ukuyisebenzisa:
Ingenawo uwoyela futhi ihlolwe amabala, ingangeni emanzini futhi ingagqwali, ifakwe kunoma iyiphi i-engeli, idivayisi yokuvikela: umkhawulo ophindwe kabili, ukuvikela ukushisa ngokweqile, ukuvikela ukugcwala ngokweqile.
9.Izivinini eziningi:
Isikhathi esiphelele sokuhamba ngamasekhondi angu-5 kuya kwangu-60, ahlangabezana nezidingo zezimo zokusebenza ezihlukene, izintambo zebanga elikhethekile: sebenzisa izintambo ezikwazi ukumelana nokushisa, ezingagugi lapho zishiswa, futhi ziphephile futhi zithembekile.
ipharamitha yezobuchwepheshe

Yiziphi izeluleko zokulungisa ama-valve ebhola e-pvc
★ Uma i-valve yebhola ivuza ngenxa yesibambo esixegayo, ungakwazi ukubophela isibambo nge-vise, bese usizungezisa ngokuphambene newashi ukuze uqinise isibambo.Kumele kuqashelwe ukuthi udinga ukuqaphela lapho uqinisa isibambo, ungasebenzisi amandla amaningi, ngaphandle kwalokho kulula ukuphula i-valve yebhola.
★ Uma indawo lapho i-valve yebhola ye-pvc ixhunywe khona epayipini lamanzi ayiqinile, futhi kungekho uphawu oluhle futhi kukhona ukuvuza kwamanzi, ungakwazi ukugoqa itheyiphu yezinto eziluhlaza endaweni lapho ipayipi lamanzi lixhunywe khona ebhola. i-valve, bese ufaka i-valve yebhola ngemva kokusonta, ukuze kungabikho ukuvuza kwamanzi.
★ Uma ukuvuza kwamanzi kubangelwa ukuqhekeka noma ukukhubazeka kwe-valve yebhola, i-valve yebhola endala idinga ukuhlakazwa, bese kufakwe entsha.
Kumele kuqashelwe ukuthi i-valve yebhola ye-pvc idinga ukuqhutshwa ngendlela efanele ngesikhathi sokuhlukaniswa, futhi amaphuzu amancane alandelayo kufanele enziwe.
★ Ngemuva kokuvala i-valve yebhola, kuyadingeka ukukhulula yonke ingcindezi ku-valve yebhola ngaphambi kokuhlakazeka, ngaphandle kwalokho ijwayele ingozi.Abantu abaningi abakunaki lokhu.I-valve ihlakazwa ngokushesha ngemva kokuba ivaliwe.Kusenesilinganiso esithile sokucindezela ngaphakathi.Le ngxenye yokucindezela ayikhululwa futhi ayihambisani nokuphepha komuntu siqu.
★ Ngemuva kokuthi i-valve yebhola ihlakazwe futhi ilungiswe, idinga ukufakwa ngokuphambene ne-disassembly futhi iqiniswe futhi ilungiswe, ngaphandle kwalokho kuyoba nokuvuza kwamanzi.
Uma ufuna i-valve yebhola ye-pvc ihlale isikhathi eside, kuyadingeka ukunciphisa inani lokushintshwa ngangokunokwenzeka.Uma kukhona ukuvuza kwamanzi, udinga ukukulungisa ngesikhathi ngokusho kwamathiphu amathathu esihlokweni, futhi ubuyisele ukusetshenziswa okuvamile ngokushesha ngangokunokwenzeka.
