1. Kodi valavu ya gulugufe ya PTFE Yokhala ndi Mizere Yonse ndi Chiyani?
Ma valve a gulugufe a PTFE (polytetrafluoroethylene) okhala ndi mipanda yokwanira amagwiritsidwa ntchito kwambiri m'mapaipi opangira zinthu zowononga kwambiri (monga ma acid amphamvu, maziko olimba, ndi zosungunulira zachilengedwe) chifukwa thupi la valve ndi disc zonse zili ndi PTFE yokwanira, zomwe zimapangitsa kuti dzimbiri lisawonongeke komanso kuti lisamatseke bwino. Kapangidwe ka thupi la valve kamagawidwa m'mitundu iwiri: iwiri (thupi logawanika) ndi imodzi.kapangidwe ka zidutswa ziwirindiye kapangidwe kake ka ma valve a gulugufe a PTFE okhala ndi mzere wokwanira, pomwe kapangidwe ka chidutswa chimodzi sikofala kwambiri, makamaka chifukwa cha zolepheretsa pakuyika mkati.
2. Kufanana
Kukula:DN50-DN600. Mosiyana ndi ma valve a gulugufe wamba okhala ndi mipando ya EPDM, kukula kochepa kwa mipando ya PTFE ndi DN50.
Kupanikizika:Popeza ndi yocheperako chifukwa cha zinthu za PTFE, makamaka diski yokhala ndi PTFE, ndi yoyenera kupanikizika kwakukulu kwa PN10 (PN16 imafuna zidziwitso zapadera).
Kutentha:Kutentha kwa ntchito ndi madigiri -10 mpaka 180 Celsius. (RPTFE nthawi zambiri ndi madigiri -20 mpaka 200 Celsius)
3. Kusiyana Kwakukulu ndi Kuyerekeza
3.1 Makhalidwe a Kapangidwe
Zidutswa ziwiriThupi(Thupi Logawanika): Thupi la valavu limapangidwa ndi magawo awiri (kapena zidutswa ziwiri) zomwe zimasonkhanitsidwa ndi kulumikizidwa ndi mabolt. Mzerewo umapangidwa pa theka lililonse padera musanasonkhanitse.
Thupi la chidutswa chimodzi (Thupi Lonse):Thupi la valavu limapangidwa ngati chidutswa chimodzi, ndipo mkati mwake mumafunika jekeseni kapena njira yapadera kuti mulowetse mkati mwa valavu yonse.
3.2 Njira Yopangira
Thupi la valavu ya gulugufe logawanika:Thupi la valavu limakhala ndi zigawo zapamwamba ndi zapansi zolumikizidwa ndi mabolt. Chipinda cha PTFE (kuphatikiza mphete za silicone) nthawi zambiri chimapangidwa padera chisanapangidwe. Chifukwa chake, njira yopangira chipinda cha ziwalo ziwiri ndi yosavuta ndipo sikufuna nkhungu zapadera kapena zida zomangira.
Zonsethupi la valavu ya gulugufe: Thupi la valavu limapangidwa kapena kupangidwa ngati chidutswa chimodzi, popanda malo olumikizirana apakati. Chipinda cha PTFE chimalumikizidwa ndi thupi la valavu kudzera mukupanga kapena kusungunula.
3.3 Kugwira Ntchito Kotseka
Zidutswa ziwiri (Thupi Logawanika):Kusiya kutuluka kwa madzi mbali zonse ziwiri (kolimba ngati thovu), koma pamwamba pa malo olumikizirana pamafunika kapangidwe kabwino kotseka (monga mphete za O kapena ma gasket).
Chidutswa chimodzi (thupi lonse): Palibe malo olumikizirana, malo ochepa otulutsira madzi, komanso kudalirika kwakukulu kwa kutseka.
3.4 Makulidwe Oyenera
Zidutswa ziwiri (Thupi Logawanika):Kawirikawiri imapezeka mu DN50 ~ DN600, ndipo kukula kwakukulu kwambiri n'kosavuta kupeza.
Chidutswa chimodzi (Monoblock Thupi): Kawirikawiri imangokhala ndi mainchesi ang'onoang'ono; kukula kwakukulu n'kovuta kupanga.
3.5 Kukonza Kosavuta
Thupi la valavu ya gulugufe la zidutswa ziwiri:Zabwino Kwambiri: Zosavuta kusokoneza, palibe zida zapadera zomwe zimafunika, ndipo magawo amkati kapena chimbale cha gulugufe amatha kusinthidwa payekhapayekha, zomwe zimapangitsa kuti kukonza kukhale kosavuta.
Thupi la valavu ya gulugufe la chidutswa chimodzi:Zoyipa: N'zovuta kukonza m'deralo pamene mkati mwake mwawonongeka; nthawi zambiri pamafunika kusintha thupi lonse la valavu.
3.6 Mtengo
Zidutswa ziwiri:Mpando wa PTFE uli ndi mphete ya silicone mkati mwake kuti uwonjezere kusinthasintha ndi magwiridwe antchito otseka.
Gawo limodzi: Yotsika, ngakhale kuti njira yolumikizirana ndi yovuta (PTFE ili ndi kusinthasintha kochepa ndipo ndi kovuta kuilowetsa mofanana mu valavu imodzi), ndipo kupanga ndi kovuta, kampani yathu ili ndi ukadaulo wokhwima, zomwe zimapangitsa kuti mitengo ikhale yotsika.
3.7 Zochitika Zogwiritsira Ntchito
Zidutswa ziwiri : Chosankha chachikulu, chomwe chimapezeka kwambiri m'mapaipi a mankhwala, mankhwala, madzi otayira, ndi owononga.
Gawo limodzi: Imagwiritsidwa ntchito m'mapulogalamu apadera omwe amafunidwa kwambiri (monga kutseka kwakukulu komanso osafunikira kukonza), koma imagwiritsidwa ntchito kawirikawiri mu ma valve a gulugufe a PTFE okhala ndi mipanda yokwanira.
