1. Ka Wehewehe Kumu a me ke Kumu
ʻO ka valve butterfly concentric sealing soft sealing flanged concentric butterfly valve (kahi i ʻike ʻia he "center-line butterfly valve") he ʻāpana ʻehā ʻehā i hoʻolālā ʻia no ka hoʻopaʻa ʻana a i ʻole ka throttling kahe kahe ma nā paipu. ʻO kāna mau hiʻohiʻona nui:
Hoʻolālā Concentric: Hoʻopili ʻia ke kumu valve, disc, a me ka noho ma ka axis waena like, e hana ana i kahi ʻano maʻalahi a paʻa.
Mechanism Sealing Soft: Hoʻohui ʻia kahi sila elastomeric maʻalahi (e laʻa, rubber, EPDM, NBR) i loko o ke kino valve a noho paha, e hāʻawi ana i kahi sila paʻa e pale ai i ka leakage.
Hoʻopau Flanged: Ua hoʻolako ʻia ka valve me nā pili flanged, e ʻae i ka hoʻokomo maʻalahi ma nā pipeline e like me nā kūlana e like me ANSI, DIN, a i ʻole JIS.

3. Kumu Hana
Wahi Wehe: Hoʻololi ka diski i 90° e hoʻolike me ke kuhikuhi kahe, e hoʻemi i ka hāʻule kaomi a me ka ʻae ʻana i ke kahe piha.
Kūlana Paʻa: Huli hope ka diski e kaomi i ke sila palupalu, e hana ana i kahi pani paʻa. Ke hilinaʻi nei ka hoʻolālā concentric i ka deformation elastic o ka sila e hoʻokō ai i ka sila, e hana maikaʻi loa ia no nā noi haʻahaʻa haʻahaʻa.
4. Nā mea nui a me nā pono
Hoʻopaʻa Paʻa Paʻa: Hāʻawi nā sila palupalu maikaʻi loa i ka leak, e hālāwai pinepine i nā kūlana paʻa paʻa (e laʻa, ANSI B16.104 Class VI, ISO 15848-1).
ʻO ka hana haʻahaʻa haʻahaʻa: ʻO ka hoʻolālā concentric a me ka sila maʻalahi e hōʻemi i ka friction, e ʻae i ka hana lima maʻalahi a hoʻohana paha me nā mea hana māmā.
Paʻa a Māmā: Ke hoʻohālikelike ʻia me nā ʻīpuka a i ʻole nā pupa honua, ʻoi aku ka liʻiliʻi o nā valve butterfly concentric a maʻalahi hoʻi e hoʻokomo i nā wahi liʻiliʻi.
Kūʻai-Effective: ʻO ka hana maʻalahi a me ka hoʻohana haʻahaʻa haʻahaʻa e hiki ai iā lākou ke kūʻai aku no nā pono kaohi kahe.
Hoʻohālikelike Media Nui: He kūpono no ka wai, ka ea, ka aila, ka wai ʻole-corrosive, a me ka media granular (me nā uhi pale abrasion).
5. Nā Kūlana ʻenehana
Paʻi Paʻi: ʻO ka haʻahaʻa haʻahaʻa a hiki i ke kaomi waena (e laʻa, PN6–PN16 / Papa 125–Papa 150).
Kaulana Mahana:
Nā elastomers maʻamau (e laʻa, NR, EPDM): -10°C i 90°C (14°F i ka 194°F).
ʻO nā sila wela wela (e laʻa, Viton®, PTFE): -20°C a hiki i 150°C (-4°F i 302°F).
Hoʻokō maʻamau:
Hoʻolālā: EN593, API 609, MSS SP-67.
Flange: ANSI B16.5, ANSI B16.10 DIN EN 1092-1,
Hoʻāʻo: API 598, (nā hoʻāʻo leakage).
6. Nā noi
ʻO nā kiwi lele lele concentric hoʻopaʻa palupalu D341X-16Qhoʻohana nui ʻia ma:
Hoʻolako wai a me ka hoʻoheheʻe wai: ʻōnaehana wai kūloko, nā mea kanu hoʻomaʻemaʻe wai, a me nā ʻupena wai.
Nā Pūnaehana HVAC: Ka mālama ʻana i ka ea, ka wai, a i ʻole ka mahu i ka hoʻomehana ʻana, ka ea, a me ka ea.
ʻOihana meaʻai a me nā mea inu: ʻO nā noi hoʻomaʻemaʻe me nā sila hoʻokō FDA (e laʻa, EPDM me nā uhi ʻano meaʻai).
Nā Kaʻina Hana Hana Nui: ʻO ka mālama ʻana i ka wai ʻaʻole ʻino i loko o nā mea kanu kemika, pepa, a me nā lāʻau lapaʻau (no ka media maʻalahi wale nō).
Kai a me ka hana moku: On/off control in kai kai a ballast system (me ka corrosion-resistant materials).
7. Ka palena a me ka noonoo
ʻAʻole kūpono no ke kaomi kiʻekiʻe (e laʻa, >PN16) a i ʻole nā noi wela loa (e laʻa, ka mahu ma luna o 150°C).
Pilikia Poha: Hiki ke ʻino nā ʻāpana metala (e laʻa, nā kino hao) ma nā wahi ʻino; hoʻonui i ke kila kila a i ʻole nā mea i uhi ʻia no nā kūlana paʻakikī.
Abrasive Media: Hiki i nā sila palupalu ke komo koke me nā wai i hoʻopiha ʻia; e noʻonoʻo i nā kiwi lele lele paʻa paʻa a i ʻole nā pale pale ʻē aʻe.
Koho Actuator: No nā valves nui-diameter a i ʻole ka hana pinepine, e hoʻohana i nā mea hana pneumatic/hydraulic e pale i ka luhi lima.
8. Hoʻokomo a mālama
Hoʻokomo:
E hōʻoia i ka hoʻopaʻa ʻia ʻana o nā flanges a hoʻopaʻa like ʻia nā bolts e pale i ka leakage.
Hōʻalo i ka hoʻokomo ʻana i ka valve ma lalo o ke koʻikoʻi o ka paipu.
Mālama:
E nānā mau i ka sila no ka ʻaʻahu ʻana a i ʻole ka haki ʻana, ʻoi aku hoʻi i nā noi kiʻekiʻe.
Lubricate i ke kumu a me ka actuator i kēlā me kēia manawa e hōʻoia i ka hana maʻemaʻe.
E hoʻololi i ke sila inā loaʻa ka leaka; ʻO kekahi mau hoʻolālā e hiki ke hoʻololi i ka sila me ka wehe ʻole ʻana i ka valve mai ka pipeline.
9. Mea hoʻolako a me nā ʻōlelo aʻoaʻo koho huahana
Palapala Pono: E hōʻoia i ka hoʻokō ʻana o nā sila i nā kūlana ʻoihana (e laʻa, FDA no ka meaʻai, ATEX no nā wahi pahū).
Nā Koho Hoʻopilikino: Hāʻawi kekahi mau mea hoʻolako i nā hoʻolālā anti-static, nā hiʻohiʻona palekana ahi, a i ʻole nā pale kūikawā (e laʻa, epoxy, PTFE) no nā noi niche.
Ka hopena
ʻO nā kiwi lele lele concentric hoʻopaʻa palupaluhe kumu kūʻai kūpono a hilinaʻi hoʻi no ka hoʻokele kaomi haʻahaʻa haʻahaʻa i nā noi koʻikoʻi ʻole. ʻO kā lākou maʻalahi, hoʻopaʻa paʻa paʻa, a me ka maʻalahi o ka mālama ʻana e lilo lākou i koho kaulana i ka wai, HVAC, a me nā ʻōnaehana ʻoihana maʻamau. No nā kaiapuni koʻikoʻi, ʻoi aku ka hoʻomaikaʻi ʻana i nā hoʻolālā eccentric a i ʻole nā mea waiwai. E noʻonoʻo mau i nā waiwai media, nā kūlana hana, a me nā koi hoʻokō e koho i ka valve kūpono loa no kāu mau pono.
Kekahi rubber noho concentriclele lele, e like me ka wafer butterfly valve, lug butterfly valveD7L1X-16Q, Y-strainer, wafer check valve,kiwi pukaZ41X-16Qkoi, hiki ke launa meTWS valvehale hana, e pane mākou iā ʻoe i ka manawa mua.
