1. Iyini i-PTFE Fully Lined Butterfly Valve?
Amavalvu e-butterfly agcwele i-PTFE (polytetrafluoroethylene) asetshenziswa kabanzi ezinhlelweni zamapayipi ezinto ezigqwalisa kakhulu (njenge-acid enamandla, izisekelo eziqinile, kanye nezinyibilikisi eziphilayo) ngoba kokubili umzimba wevalvu kanye nediski kugcwele i-PTFE, okunikeza ukumelana nokugqwala okuhle kakhulu kanye nokusebenza kokuvala. Isakhiwo somzimba wevalvu sihlukaniswe kakhulu ngezinhlobo ezimbili: umzimba onezicucu ezimbili (umzimba ohlukanisiwe) kanye nomzimba onezicucu eyodwa.isakhiwo esinezingcezu ezimbilikuwumklamo oyinhloko wamavalvu ebhabhathane agcwele i-PTFE, kuyilapho umklamo wengxenye eyodwa ungavamile, ikakhulukazi ngenxa yemikhawulo enqubweni yokufakwa kwendwangu.
2. Ukufana
Usayizi:DN50-DN600. Ngokungafani namavalvu ebhabhathane avamile anezihlalo ze-EPDM, usayizi omncane wezihlalo ze-PTFE yi-DN50.
Ingcindezi:Inqunyelwe yizinto ze-PTFE, ikakhulukazi idiski eline-PTFE, ifaneleka ukucindezela okuphezulu kwe-PN10 (i-PN16 idinga imininingwane ekhethekile).
Izinga lokushisa:Izinga lokushisa lokusebenza lingu--10 kuya ku-180 degrees Celsius. (I-RPTFE ivame ukuba ngu--20 kuya ku-200 degrees Celsius)
3. Umehluko Omkhulu Nokuqhathanisa
3.1 Izici Zesakhiwo
Izingcezu ezimbiliUmzimba(Umzimba Ohlukanisiwe): Umzimba wevalvu uqukethe izingxenye ezimbili (noma izingcezu ezimbili) ezihlanganiswe futhi zixhunywe ngamabhawodi. Ulwelwesi lwenziwa engxenyeni ngayinye ngokwehlukana ngaphambi kokuhlanganiswa.
Umzimba One-piece (Umzimba Wonke):Umzimba wevalvu uphonswa noma wenziwa ngomshini njengocezu olulodwa, futhi ulwelwesi ludinga ukubumba ngomjovo noma inqubo ekhethekile yokumbozwa ngokuphelele.
3.2 Inqubo Yokukhiqiza
Umzimba we-valve yebhabhathane elihlukanisiwe:Umzimba wevalvu uqukethe izingxenye ezingaphezulu nezingezansi ezixhunywe ngamabhawodi. Ulwelwesi lwe-PTFE (kufaka phakathi amasongo e-silicone) luvame ukwakheka ngokwehlukana ngaphambi kokuhlanganiswa. Ngakho-ke, inqubo yolwelwesi lomzimba onezingcezu ezimbili ilula futhi ayidingi isikhunta noma amathuluzi akhethekile okuhlanganiswa.
Konkeumzimba wevalvu yebhabhathane: Umzimba wevalvu uphonswa noma wenziwe ngomshini njengento eyodwa, ngaphandle kwezindawo eziphakathi nendawo zokuhlangana. Ulwelwesi lwe-PTFE luhlanganiswe nomzimba wevalvu ngokubumba noma ukuthungwa okuhlanganisiwe.
3.3 Ukusebenza Kokuvala
Izingcezu ezimbili (Umzimba Ohlukanisiwe):Akukho ukuvuza okuqondile (okungenamabhamuza), kodwa ubuso obuhlangene budinga ukwakheka okuhle kokuvala (njengezindandatho ze-O noma ama-gasket).
Ingxenye eyodwa (umzimba wonke): Azikho izindawo ezihlangene, izindawo ezimbalwa zokuvuza ezingaba khona, kanye nokuthembeka okuphezulu kokuvala.
3.4 Osayizi Abasebenzayo
Izingcezu ezimbili (Umzimba Ohlukanisiwe):Itholakala kakhulu ku-DN50 ~ DN600, futhi ngisho nosayizi abakhulu bayatholakala kalula.
Ingxenye eyodwa (Umzimba we-Monoblock): Kukhawulelwe kakhulu kumadayamitha amancane; osayizi abakhulu kunzima ukubenza.
3.5 Ukulula Kokulungisa
Umzimba wevalvu yebhabhathane enezingcezu ezimbili:Kuhle Kakhulu: Kulula ukuyihlukanisa, akukho mathuluzi akhethekile adingekayo, futhi izingxenye ze-lining noma i-butterfly disc zingashintshwa ngazinye, okwenza ukulungiswa kube lula.
Umzimba we-valve yebhabhathane enengxenye eyodwa:Okubi: Kunzima ukulungisa endaweni lapho ulwelwesi lonakele; ngokuvamile kudinga ukushintshwa komzimba wonke wevalvu.
3.6 Izindleko
Izingcezu ezimbili:Ngaphezulu, isihlalo se-PTFE sinendandatho ye-silicone ngaphakathi ukuze kwandiswe ukunwebeka nokusebenza kokuvala.
Ucezu olulodwa: Iphansi, yize inqubo yokufakwa kwendwangu iyinkimbinkimbi (i-PTFE ayinakunwebeka kahle futhi kunzima ukuyifaka ngokulinganayo emzimbeni we-valve eyodwa), futhi ukukhiqiza kuyinselele, inkampani yethu inobuchwepheshe obuvuthiwe, okuholela emananini aphansi.
3.7 Izimo Zokusebenza
Izingcezu ezimbili : Ukukhetha okujwayelekile, okuvame kakhulu emipayipini yamakhemikhali, yezemithi, yamanzi angcolile, kanye neyokugqwala.
Ucezu olulodwa: Isetshenziswa ezicelweni ezikhethekile ezifunwa kakhulu (njengezidingo zokuvala eziphezulu kakhulu futhi azikho izidingo zokulungisa), kodwa ayisetshenziswa kakhulu kuma-valve e-butterfly agcwele i-PTFE.
