ʻO ka hana a me ke alakaʻi no ka hoʻohana ʻana

Hoʻolālā ʻia nā puʻupuʻu valve no ka pale ʻana i nā leaks i hoʻokumu ʻia e ke kaomi, corrosion, a me ka hoʻonui ʻana i ka wela ma waena o nā ʻāpana. ʻOiai kokoke pau nā flangedpili's Pono nā valves i nā gaskets, ʻokoʻa kā lākou noi kikoʻī a koʻikoʻi ma muli o ke ʻano valve a me ka hoʻolālā. Ma keia pauku,TWSe wehewehe i nā kūlana hoʻokomo valve a me ke koho ʻana i nā mea gasket.

I. ʻO ka noi mua o nā gaskets aia ma ka flange ami o nā pili valve.

ʻO ka valve hoʻohana maʻamau

1. Puka puka
2. Poepoe Valve
3. Puka kupua(ʻoi aku ka concentric a me ka lua eccentric flanged butterfly valve)
4. E nānā i ka valve

I loko o kēia mau pahu, ʻaʻole hoʻohana ʻia ka gasket no ka hoʻoponopono kahe ʻana a i ʻole ke sila ʻana i loko o ka valve ponoʻī, akā hoʻokomo ʻia ma waena o ʻelua flanges (ma waena o ka flange o ka valve ponoʻī a me ka flange pipe). Ma ka hoʻopaʻa ʻana i nā bolts, hoʻokumu ʻia ka ikaika clamping e hana i kahi sila static, e pale ana i ka leakage o ka waena ma ka pilina. ʻO kāna hana ʻo ia ka hoʻopiha ʻana i nā āpau liʻiliʻi liʻiliʻi ma waena o nā ʻaoʻao flange metala ʻelua, e hōʻoia i ka 100% sila i ka pilina.

II.Ka hoʻohana ʻana i ka Gasket ma ka Valve "Valve Cover"

Hoʻolālā ʻia nā pahu he nui me nā kino valve ʻokoʻa a me nā uhi no ka maʻalahi o ka mālama ʻana i loko (e laʻa, ka hoʻololi ʻana i nā noho valve, nā pahu pahu, a i ʻole ka holoi ʻana i nā ʻōpala), a laila hoʻopaʻa pū ʻia. Pono pū kekahi gasket ma kēia pili 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 pono ai ka hoʻohana ʻana i ka gasket a i ʻole ka O-ring.
2. Hoʻohana ʻia ka gasket ma kēia kūlana ma ke ʻano he seal static e pale ai i ka lewa mai ke kino valve i ka lewa.

III. ʻO ke kinoea kūikawā no nā ʻano valve kikoʻī

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

1. Puka kupua-pahu noho kiwi

• ʻO ka noho o ka valve butterfly he apo apo maoli nō 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 o ka lelediscpani ʻia, kaomi i ka pahu noho valve e hana i kahi sila ikaika (e like me ka butterflydisckahuli).
• ʻO ka mea maʻamau ka lāʻau lapaʻau (e laʻa, EPDM, NBR, Viton) a i ʻole PTFE, i hoʻolālā ʻia e hoʻokipa i nā ʻano media a me nā kūlana wela.

2. Pahu kinipopo-Valve Noho Gasket

• ʻO ka noho kiwi o ka pahu pōpō he ʻano gasket nō hoʻi, i hana maʻamau ʻia mai nā mea like me PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), a i ʻole nā ​​​​plastika i hoʻoikaika ʻia.
• Hāʻawi ia i kahi sila ma waena o ka pōleʻa 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 hoʻoikaika (pili i ka pōpō ʻōwili).

IV. ʻAʻole hoʻohana pinepine ʻia nā pahu wai me nā gaskets?

1. Welded valves: Hoʻopili pololei ʻia ke kino valve i ka pipeline, e hoʻopau ana i ka pono o nā flanges a me nā gaskets.
2. ʻO nā kiwi me nā pili pili: Hoʻohana maʻamau lākou i ka sila ʻana i ka wili (e like me ka lipine maka a i ʻole sealant), e hoʻopau pinepine i ka pono o nā gaskets.
3. Nā kiwikā monolithic: ʻO kekahi mau kiwi pōpō kumu kūʻai haʻahaʻa a i ʻole nā ​​kiwi kūikawā e hōʻike ana i kahi kino valve hui pū ʻia ʻaʻole hiki ke hoʻokaʻawale ʻia, no laila ʻaʻole i loaʻa kahi pahu uhi uhi.
4. ʻO nā pāpaʻi me nā apo-O a i ʻole nā ​​puʻupuʻu i uhi ʻia metala: Ma nā noi kiʻekiʻe, wela kiʻekiʻe, a i ʻole nā ​​​​mea hoʻohana kūikawā, hiki ke hoʻololi i nā mea hoʻoheheʻe hoʻopaʻa paʻa kiʻekiʻe.

V. Hōʻuluʻulu manaʻo:

ʻO Valve gasket kahi ʻano o ka ʻoki ʻoki kī nui, hoʻohana nui ʻia i ka pilina pipeline o nā ʻāpana flange like ʻole, a hoʻohana pū ʻia hoʻi i ka hoʻopaʻa ʻana i ka uhi valve o nā kīwaha he nui. I ke koho ʻana, pono e koho i ke ʻano gasket kūpono a me ke ʻano e like me ke ʻano o ka valve, mode pili, medium, temperature and pressure.
