Wedge Gate Valve mo te hinu En1984 Haina wheketere
He aha te Gate valve mo te hinu?
i te mea ko nga reera o te kuaha poro, ko nga waahanga whakatuwhera me te kati o te keeti kuaha mo te hinu ko te kuaha, he ahua o te poro, koira te take i kiia ai he marere keeti.Ka taea anake te whakatuwhera me te kati katoa te takirere o te kuaha o te kuaha, kaore e taea te whakatika me te tarai.I hangaia te paera o te kuaha ki te whakamahi kia tino tuwhera, kia kati rawa ranei, na te mea na te ahua o ona kaipatu he ahua o te poro. , ki te whakahaeretia he wahanga tuwhera, ka nui te mate o te pehanga, ka pakaru te mata o te hiri i raro i te paheketanga o te wai.Ko te ahuatanga matua o te DIN-EN wedge gate valve ko tana mata hiri i waenga i te "kuwaha" me tona nohoanga he papatahi, na reira ka iti rawa te mate pehanga.
Puti kuaha mo te hinu
- 2) Ka rite nga flanges ki te EN1092-1, me te kanohi ki te kanohi EN558-1 ranei o mua Tiamana paerewa DIN3202
- 3) I whakamatauria me te tirotirohia kia rite ki te EN12266, BS6755 me te ISO5208
Ko nga ahuatanga matua o te Gate valve mo te hinu
Nga waahanga matua
- Te poro hangore me te whakapiri kakau-waa o waenganui iti, i roto i te CA15 totoka (13Cr), he mata pakeke ranei ki te 13Cr, SS 316, Monel, Stellite Gr.6 ranei.Ka werohia te poro, ka werohia ki te whakaata me te arahi kia kore e toia me te pakaru o te nohoanga.
- Nga flanges: EN1092-1, PN10-16-25-40-63-100, etahi atu rahinga flanges ranei i tonoa
- Kei te watea ano he porowhita CF8M Stellite hardfaced i runga i te tono.
- He iti te parenga rere me te mate pehanga, na te rere tika me te poro tuwhera tonu.
- Ko te ahua kiato, he hanga ngawari, he ngawari ki te hanga me te tiaki, me te whānuitanga o te tono.
- he wa roa ki te kati me te puhoi te nekehanga o te poro, karekau he ahua hama wai mo nga marere kuaha poro.
