Pālua Flange Pulelehua Valve
ʻO kakiwikā pulelehua flange pāluahe kiwikā pulelehua noho paʻa me nā flanges hoʻohui i hoʻolei ʻia ma nā wēlau ʻelua, e ʻae ana i ka pilina pololei i ka pipeline me ka ʻole o nā adapters hou. E like me nā kiwikā pulelehua noho paʻa a pau, he kiwikā hapaha-huli ia: he disc poepoe i kau ʻia ma ke kikowaena o ke kino e lawelawe ana ma ke ʻano he ʻano pani, i hoʻopili ʻia i kahi actuator a i ʻole ka lima ma o kahi ʻau waena. ʻO ka hoʻohuli piha ʻana o 90-degere e wehe a pani piha paha i ka kiwikā nolawelawe hoʻokaʻawale.
Ke ʻole ka wili ʻana o ka diski i ka hapaha piha, ua hāmama hapa ka valve — e hiki ai ke kikoʻīhoʻoponopono kahema nā kihi wehe like ʻole. Hoʻopili piha ʻia ka noho laholio ma ke kino, e hōʻoiaʻiʻo ana i ka sila ʻelua-kuhikuhi hilinaʻi ma ka laulā nui piha, me ke koi nuinā kūlana hana vacuum.
Ua hoʻolālā ʻia nā kiwikā pepeke flange pālua ʻo Nortech me kahi ana maka-a-maka lōʻihi e like me EN 558-1 Series 13, e kūpono ai lākou no nā ʻano hana maʻamau a me nā hana kaumaha e like me nā pūnaewele hoʻolaha wai, nā hale hana hoʻomaʻemaʻe wai, nā pā, nā hale hana mana, a me nā ʻōnaehana paipu anawaena nui. Hiki ke hoʻohana ʻia ka kiwikā ma ke ʻano he kiwikā hoʻokaʻawale, kahi piula hoʻokuʻu ma ka hopena o ka paipu, a i ʻole kahi mea hoʻomalu kahe. No nā paipu anawaena nui, ʻo ka hoʻonohonoho flange pālua ke koho maʻamau.
Maka lōʻihi a maka i ka EN 558-1 Series 13— hāʻawi ka hoʻolālā flange pālua i kahi pilina paʻa a kākoʻo ponoʻī i kūpono loa i nā paipu anawaena nui a me nā noi pōʻaiapuni kiʻekiʻe kahi e koʻikoʻi ai ke kūpaʻa a me ka hoʻonohonoho ʻana o ka valve.
