Hoʻolauna ʻana o ka Valve Pepeiao

Hoʻolauna:

He kiwikā pulelehuano kahi ʻohana o nā valves i kapa ʻianā kiwikā hapaha-huli. I ka hana ʻana, ua wehe piha ʻia a pani ʻia paha ka valve ke hoʻohuli ʻia ka diski i ka hapaha huli. ʻO ka "butterfly" kahi disc metala i kau ʻia ma luna o kahi koʻokoʻo. Ke pani ʻia ka valve, ua hoʻohuli ʻia ka disc i mea e ālai loa ai i ke alahele. Ke wehe piha ʻia ka valve, ua hoʻohuli ʻia ka disc i ka hapaha huli i mea e ʻae ai i kahi hele ʻana o ke wai me ka palena ʻole. Hiki ke wehe mālie ʻia ka valve e hoʻēmi i ke kahe.

Aia nā ʻano kīʻaha pepeke like ʻole, i hoʻololi ʻia kēlā me kēia no nā kaomi like ʻole a me nā hoʻohana like ʻole. ʻO ka kīʻaha pepeke zero-offset, ka mea e hoʻohana ana i ka maʻalahi o ka rubber, ʻo ia ka helu kaomi haʻahaʻa loa. ʻO ka kīʻaha pepeke offset pālua hana kiʻekiʻe, i hoʻohana ʻia i nā ʻōnaehana kaomi kiʻekiʻe iki, ua offset ʻia mai ka laina waena o ka noho disc a me ke sila kino (offset hoʻokahi), a me ka laina waena o ka bore (offset ʻelua). Hoʻokumu kēia i kahi hana cam i ka wā o ka hana e hāpai i ka noho mai loko mai o ke sila e hopena ana i ka friction liʻiliʻi ma mua o ka mea i hana ʻia ma ka hoʻolālā offset zero a hoʻemi i kona ʻano e komo ai. ʻO ka kīʻaha kūpono loa no nā ʻōnaehana kaomi kiʻekiʻe ʻo ia ka kīʻaha pepeke triple offset. Ma kēia kīʻaha ua offset ʻia ke axis pili noho disc, kahi e hana ai e hoʻopau loa i ka pilina paheʻe ma waena o ka disc a me ka noho. I ke ʻano o nā kīʻaha triple offset, ua hana ʻia ka noho me ka metala i hiki ke mīkini ʻia e like me ka hoʻokō ʻana i kahi pani paʻa pehu i ka wā e pili ana me ka disc.

Nā ʻano

1. Nā kiwikā pulelehua concentric– he noho laholio kūpaʻa ko kēia ʻano kiwikā me kahi diski metala.
2. Nā kiwikā pulelehua ʻokoʻa pālua(nā kiwikā pulelehua hana kiʻekiʻe a i ʻole nā ​​kiwikā pulelehua pālua-offset) - hoʻohana ʻia nā ʻano mea like ʻole no ka noho a me ka disc.
3. Nā kiwikā pulelehua ʻokoʻa-ʻekolu(nā kiwikā pulelehua ʻekolu-offset) - he hoʻolālā noho laminated a i ʻole metala paʻa nā noho.

Nā kiwikā pulelehua ʻano wafer

ʻO kakiwikā pulelehua kaila waferua hoʻolālā ʻia e mālama i kahi sila e kūʻē i ka ʻokoʻa kaomi bi-directional e pale aku i kekahi kahe hoʻi i loko o nā ʻōnaehana i hoʻolālā ʻia no ke kahe unidirectional. Hoʻokō ia i kēia me kahi sila paʻa; ʻo ia hoʻi, gasket, o-ring, mīkini pololei, a me kahi alo valve pālahalaha ma nā ʻaoʻao uka a me lalo o ka valve.

Kiwikā pulelehua kaila-lula

Nā kiwikā ʻano lughe mau mea hoʻokomo wili ma nā ʻaoʻao ʻelua o ke kino valve. ʻAe kēia iā lākou e hoʻokomo ʻia i loko o kahi ʻōnaehana me ka hoʻohana ʻana i ʻelua mau seti o nā bolts a me nā nati ʻole. Hoʻokomo ʻia ka valve ma waena o ʻelua mau flanges me ka hoʻohana ʻana i kahi set o nā bolts no kēlā me kēia flange. ʻAe kēia hoʻonohonoho i kēlā me kēia ʻaoʻao o ka ʻōnaehana paipu e hoʻokaʻawale ʻia me ka ʻole o ka hoʻopilikia ʻana i kekahi ʻaoʻao.

ʻO ka valve butterfly ʻano lug i hoʻohana ʻia i ka lawelawe make hope maʻamau he helu kaomi haʻahaʻa. No ka laʻana, ʻo ka valve butterfly ʻano lug i kau ʻia ma waena o ʻelua mau flanges he helu kaomi 1,000 kPa (150 psi). ʻO ka valve like i kau ʻia me hoʻokahi flange, i ka lawelawe make hope, he helu 520 kPa (75 psi). He kūpaʻa loa nā valves lugged i nā kemika a me nā mea hoʻoheheʻe a hiki ke lawelawe i nā mahana a hiki i 200 °C, ʻo ia ka mea e lilo ai i hopena versatile.

Hoʻohana i ka ʻoihana

I loko o nā ʻoihana lāʻau lapaʻau, kemika, a me ka meaʻai, hoʻohana ʻia kahi kiwikā pepeke e hoʻopau i ke kahe o ka huahana (paʻa, wai, kinoea) i loko o ke kaʻina hana. Hana pinepine ʻia nā kiwikā i hoʻohana ʻia ma kēia mau ʻoihana e like me nā alakaʻi cGMP (hana hana maikaʻi o kēia manawa). Hoʻololi pinepine nā kiwikā pepeke i nā kiwikā poepoe i nā ʻoihana he nui, ʻoiai ka petroleum, ma muli o ke kumukūʻai haʻahaʻa a me ka maʻalahi o ke kau ʻana, akā ʻaʻole hiki ke 'pigged' ʻia nā pipeline me nā kiwikā pepeke no ka hoʻomaʻemaʻe ʻana.
