Hana a me ke Alakaʻi Noi o ka Valve Gasket

Ua hoʻolālā ʻia nā gaskets valve e pale i nā leaka i hoʻokumu ʻia e ke kaomi, ka pala, a me ka hoʻonui ʻana/ʻaelike wela ma waena o nā ʻāpana. ʻOiai kokoke i nā flanges āpaupili ʻana's Pono nā valves i nā gaskets, ʻokoʻa kā lākou noi kikoʻī a me ke koʻikoʻi ma muli o ke ʻano a me ka hoʻolālā o ka valve. Ma kēia ʻāpana,TWSe wehewehe i nā kūlana hoʻokomo valve a me ke koho ʻana i nā mea gasket.

I. ʻO ka hoʻohana nui ʻana o nā gaskets ma ka hui flange o nā pilina valve.

ʻO ka valve hoʻohana maʻamau

1. Kiwikā Puka
2. Kiwikā Honua
3. kiwikā pulelehua(ʻoi aku ka concentric a me ka pālua eccentric flanged butterfly valve)
4. Kiwikā nānā

I loko o kēia mau kiwikā, ʻaʻole hoʻohana ʻia ka gasket no ka hoʻoponopono ʻana i ke kahe ʻana a i ʻole ke sila ʻana i loko o ka kiwikā ponoʻī, akā ua hoʻokomo ʻia ma waena o ʻelua mau flanges (ma waena o ka flanges o ka kiwikā ponoʻī a me ka flanges paipu). Ma ka hoʻopaʻa ʻana i nā bolts, ua hoʻokumu ʻia ka ikaika clamping lawa e hana i kahi sila static, e pale ana i ka leakage o ka medium ma ka pilina. ʻO kāna hana ka hoʻopiha ʻana i nā hakahaka liʻiliʻi ʻaʻole like ma waena o nā ʻili flanges metala ʻelua, e hōʻoiaʻiʻo ana i ka sila 100% ma ka pilina.

II.Ka Hoʻopili ʻana o ka Gasket i loko o ka "Valve Cover" Valve

Ua hoʻolālā ʻia nā kiwikā he nui me nā kino kiwikā kaʻawale a me nā uhi no ka mālama maʻalahi ʻana i loko (e laʻa, ke pani ʻana i nā noho kiwikā, nā kiwikā disc, a i ʻole ka hoʻomaʻemaʻe ʻana i nā ʻōpala), a laila hoʻopaʻa ʻia. Pono pū ʻia kahi gasket ma kēia pilina e hōʻoia i kahi sila paʻa.

1. ʻO ka pilina ma waena o ka uhi valve a me ke kino valve o ka valve puka a me ka valve honua e koi pinepine i ka hoʻohana ʻana i kahi gasket a i ʻole O-ring.
2. ʻO ka gasket ma kēia kūlana e lawelawe pū ana ma ke ʻano he sila static e pale ai i ka medium mai ka leaka ʻana mai ke kino valve i ka lewa.

III. Gasket kūikawā no nā ʻano valve kikoʻī

Hoʻokomo kekahi mau valve i ka gasket ma ke ʻano he ʻāpana o kā lākou hui sila koʻikoʻi, i hoʻolālā ʻia e hoʻohui ʻia i loko o ka ʻano valve.

1. kiwikā pulelehua-gasket noho valve

• ʻO ka noho o ka valve butterfly he gasket apo ia, i kaomi ʻia i loko o ka paia o loko o ke kino valve a i hoʻokomo ʻia a puni ka disc butterfly.
• I ka wā e hana ai ka pulelehuapāpani ʻia, kaomi ia i ka gasket noho valve e hana i kahi sila ikaika (e like me ka pulelehuapāhoʻohuli).
• ʻO ka mea maʻamau he laholio (e like me EPDM, NBR, Viton) a i ʻole PTFE, i hoʻolālā ʻia e hoʻokō i nā ʻano pāpaho a me nā kūlana mahana.

2. Pākuʻi Pōpō-Pakete Noho Valve

• ʻO ka noho kiwikā o ka kiwikā pōpō he ʻano gasket nō hoʻi, i hana pinepine ʻia mai nā mea e like me PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), a i ʻole nā ​​​​plastic i hoʻoikaika ʻia.
• Hāʻawi ia i kahi sila ma waena o ka pōpō a me ke kino valve, e lawelawe ana ma ke ʻano he sila static (e pili ana i ke kino valve) a me kahi sila dynamic (e pili ana i ka pōpō wili).

IV. ʻO wai nā kiwikā i hoʻohana pinepine ʻole ʻia me nā gaskets?

1. Nā kiwikā i hoʻopaʻa ʻia: Hoʻopaʻa pololei ʻia ke kino kiwikā i ka pipeline, e hoʻopau ana i ka pono no nā flanges a me nā gaskets.
2. Nā Valve me nā pilina wili: Hoʻohana pinepine lākou i ka sila wili (e like me ka lipine mea maka a i ʻole ka sila), e hoʻopau pinepine ana i ka pono no nā gaskets.
3. Nā kiwikā Monolithic: Loaʻa i kekahi mau kiwikā pōpō haʻahaʻa ke kumu kūʻai a i ʻole nā ​​kiwikā kūikawā kahi kino kiwikā i hoʻohui ʻia ʻaʻole hiki ke wehe ʻia, no laila nele i kahi gasket uhi kiwikā.
4. Nā kiwikā me nā apo-O a i ʻole nā ​​​​gaskets i wahī ʻia i ka metala: I nā noi kiʻekiʻe, wela kiʻekiʻe, a i ʻole nā ​​​​​​hana waena kūikawā, hiki i nā hoʻonā sila holomua ke pani i nā gaskets ʻaʻole metala maʻamau.

Hōʻuluʻulu Manaʻo:

ʻO ka gasket valve kahi ʻano ʻokiʻoki maʻamau o ka mea sila kī, hoʻohana nui ʻia ia i ka pilina pipeline o nā valve flange like ʻole, a hoʻohana ʻia hoʻi i ka sila ʻana o ka uhi valve o nā valve he nui. I ke koho ʻana, pono e koho i ka mea gasket kūpono a me ke ʻano e like me ke ʻano o ka valve, ke ʻano pili, ka waena, ka mahana a me ke kaomi.
