Kiwikā Pulelehua ʻAno U
ʻO kakiwikā pulelehua U-ʻano pālua flangedhe kiwikā pulelehua noho paʻa - i kapa ʻia hoʻi he kiwikā pulelehua "concentric", "rubber lined", a i ʻole "rubber seated". Loaʻa iā ia kahi noho laholio paʻa i hoʻopili pololei ʻia ma ke kino, ma waena o ke anawaena o waho o ka disc a me ka paia o loko o ka kiwikā, e hōʻoiaʻiʻo ana i ka sila paʻa pono o ka pehu ma nā ʻano hana like ʻole.
He kiwikā hapaha-huli e hoʻohuli ana i 90° e wehe piha a pani paha i ke kahe wai. ʻO ka diski poepoe - i kau ʻia ma ke kikowaena o ke kino kiwikā - lawelawe ma ke ʻano he ʻano pani mua, i hoʻopili ʻia i kahi mea hoʻoikaika a i ʻole ka lima ma o kahi ʻau waena. Ke hoʻopau ka diski i kahi hoʻohuli piha 90-degere, hana ka kiwikā ma ke ʻano hekiwikā hoʻokaʻawaleKe wehe hapa ʻia, hana ia ma ke ʻano hekiwikā hoʻoponopono kahe, e ʻae ana i ka mana pololei ma nā kihi wehe like ʻole.
Ma ke ʻano o ke ʻano hoʻonohonoho, ua hoʻokaʻawale ʻia ke ʻano U ma ke ʻano hekiwikā ʻano waferʻOiai he ʻelua mau flanges integral i hoʻolei ʻia ma ke kino, ʻo kona mau ana maka-a-maka ua like ia me ke ʻano wafer maʻamau - compact i ka hoʻolālā, kūpono ma waena o ʻelua mau flanges pipeline me nā studs e hele ana mai kekahi ʻaoʻao a i kekahi ʻaoʻao. Paʻa ka valve ma kahi a sila ʻia e nā gaskets ma lalo o ke kaomi stud. Hoʻolālā kūikawā ʻia nā flanges integral e kōkua i ka hoʻonohonoho ʻana a me ke kau ʻana, e hoʻolilo ana i kēia hoʻonohonoho i koho makemake ʻia no nā nui paipu nui.
Ma Nortech, uhi nā kiwikā pulelehua noho paʻa i ke ʻano wafer a me ke ʻano lug iā DN32–DN600. No nā anawaena nui aʻe, hoʻohana ʻia ka kiwikā pulelehua flanged ʻano U - e hāʻawi ana i ke kūkulu noho paʻa like i hōʻoia ʻia i nā nui DN350–DN1200 (14″–48″).
ʻAno U vs. Wafer vs. Flanged pālua— ua like ke kūkulu ʻana o nā ʻano hoʻonohonoho ʻekolu i ke kūpaʻa akā ʻokoʻa ke ʻano o kā lākou hoʻopili ʻana i ka pipeline. Hōʻike ka hoʻohālikelike ma lalo nei i nā ʻokoʻa koʻikoʻi i ka hoʻopili hope a me ke ʻano hoʻonohonoho.
