Ma ka hale hana ʻo Jinbin, he pūʻulu o ka ʻekenā kiwikā pepekeua pau. Ua kapa ʻia hoʻi ʻo LTkiwikā pulelehua kaila lug, me ka nui o DN400 a ua lako me nā mea hoʻoikaika pneumatic. Ua hoʻomaka lākou i ka lawe ʻana a ke hele nei no Saudi Arabia.

ʻO ka valve butterfly ʻano LT lug kahi valve i hoʻohana pinepine ʻia i nā ʻōnaehana wai waena a me ke kaomi haʻahaʻa. ʻO kona mau pono nui e pili ana i ka hoʻonohonoho maʻalahi, ka sila hilinaʻi a me ke kū'ē haʻahaʻa o ke kahe, e kūpono ai no ka kaohi ʻana i ka lawe ʻana i ka wai i nā kūlana hana like ʻole. Hiki ke hoʻopaʻa ʻia nā lugs ma nā wēlau ʻelua o ke kino valve ma o nā bolts me ka hilinaʻi ʻole i ke kaumaha o ka flange paipu, a kūpono me nā kūlana flange like ʻole e like me ANSI a me GB. I ka wā e hana ai i ka mālama ʻana, hiki ke wehe ʻokoʻa ʻia ke kino valve me ka ʻole o ka hoʻopilikia ʻana i ka pipeline a me ka ʻōnaehana pipeline, e hoʻonui nui ana i ka pono o ka mālama ʻana.

He ʻano paʻa ko ke kino o ka valve a he 1/3 a 1/2 wale nō kona kaumaha o ka valve puka o ke ʻano like. ʻAʻohe mea keakea i ke ala kahe a kokoke i ke ʻano pololei, me kahi coefficient pale kahe liʻiliʻi, hiki ke hōʻemi i ka hoʻohana ʻana i ka ikehu no ka lawe ʻana. Kākoʻo ia i ka hoʻokele manual, uila a pneumatic paha, me kahi torque hoʻololi liʻiliʻi, e kūpono ai no nā hiʻohiʻona anawaena nui (DN50-DN2000).

Hoʻohana nui ʻia ka valve butterfly lug ʻano LT i nā hiʻohiʻona aʻe:

1. Hoʻolako wai a me ka hoʻokahe wai a me ka mālama wai: Nā pūnaewele hoʻolako wai a me nā hoʻokahe wai o ke kūlanakauhale, nā mea kanu mālama wai ʻino, nā hana wai, i hoʻohana ʻia no ka halihali a me ka interception o ka wai maʻemaʻe, ka wai ʻino a me ka wai i hoʻihoʻi ʻia. Hiki i ke ʻano palupalu ke hoʻokō i nā koi leaka haʻahaʻa a kūpono no nā kūlana kahe nui.

2. ʻOihana Petrochemical a me ka ʻOihana Laulā: Ka lawe ʻana i nā mea pāpaho e like me ka ʻaila maka, nā huahana ʻaila i hoʻomaʻemaʻe ʻia, nā mea hoʻoheheʻe kemika, nā hopena waikawa a me ka alkali, a pēlā aku. Hiki i ke ʻano paʻa ke hoʻopaʻa i nā kūlana hana mahana a me ke kaomi waena, a kūpono ke ʻano hoʻonohonoho lug no nā koi mālama pinepine o nā pipeline kemika.

3.Hvac a me nā ʻōnaehana hale: Kaʻapuni wai ea waena, nā pūnaewele hoʻomehana waena, nā ʻōnaehana wai hoʻoluʻu ʻoihana. Loaʻa i ke ʻano sila palupalu kahi hopena sila maikaʻi, kūpono no nā kūlana hana haʻahaʻa a me ke kaomi haʻahaʻa, maʻalahi e hana a mālama i ka ikehu, a hoʻemi i ke kumukūʻai hana o ka ʻōnaehana.

4. ʻOihana Hana Moku a me Metallurgical: ʻŌnaehana wai ballast moku, wai hoʻoluʻu i ka ʻoihana metallurgical, nā pipeline lawe ea i hoʻopaʻa ʻia. Loaʻa i ka ʻōnaehana lug ka hana anti-vibration ikaika a kūpono no nā wahi hoʻonohonoho paʻakikī e like me nā moku puʻupuʻu a i ʻole nā ​​​​​​wahi ʻoihana.
