Puka Puka Puka Puka Puka

Aia kekahi mau ʻokoʻa nui ma waena o ka pili flanged a me ka pili ʻana i ka threaded screwed ma nā ʻīpuka puka?

Hoʻohana ʻia nā flanges like ʻole, nā bolts a me nā gaskets e hoʻopili ai i nā paipu a me nā kiwi. Ua kūpono lākou i nā anawaena paipu nui a me nā laina ʻoihana kiʻekiʻe. He maʻalahi ka wehe ʻana no ka hoʻoponopono ʻana, a paʻa mau ka hana sealing no ka wā lōʻihi.

Hoʻopili pololei nā ʻaoʻao wili i nā paipu liʻiliʻi me ka ʻole o nā lepa. He liʻiliʻi ke kumu kūʻai a lawe liʻiliʻi i nā wahi hoʻonohonoho, akā kūpono wale i nā laina lawelawe māmā liʻiliʻi. Hiki ke hoʻoheheʻe ʻia nā ami ʻili ma lalo o ka wela kiʻekiʻe a me nā kūlana hana paʻakikī, a paʻakikī ke wehe ʻia ma hope.

Nā mea nui

Hiki paha ke hoʻohana i nā ʻīpuka flanged e hoʻolohi a hoʻololi paha i ke kahe wai?

ʻAʻole mākou manaʻo e hoʻoheheʻe ʻia me nā ʻīpuka flanged. Hoʻonohonoho pono ʻia kēia mau valves no nā mokuʻāina hāmama a pani piha paha.

ʻO ka mālama ʻana i ka wedge half-open e hiki ke hoʻopā mau ʻia ka mea kahe wikiwiki i ka ʻili o ka sila, kahi e ʻakaʻaka a ʻaʻahu koke i ka noho, e hopena i ka leaka mau loa. Hoʻomaka ka wehe ʻana i ka haʻalulu ikaika a me ka hāmare wai e hoʻopōʻino i ka valve a me ka paipu pili. ʻOi aku ka maikaʻi o nā kiwi polū a i ʻole nā ​​kinipōpō pōlele inā makemake ʻia ka hoʻoponopono kahe.

He aha nā pae maʻamau a me nā helu kaomi e komo mau ai ka Gate Valve Flanged End?

Uhi nā nui inoa maʻamau i ka DN50 a i ka DN1200. ʻO DN80, DN100, DN150, DN200 a me DN300 kā mākou mea kūʻai nui loa no nā ʻoihana ʻenehana a me nā hana kūloko.

Loaʻa i nā māka kaomi maʻamau ʻelua ʻōnaehana koʻikoʻi:

GB maʻamau PN10, PN16, PN25, PN40; Papa ANSI 150, Papa 300, Papa 600.

Hana ʻo PN16 a me Papa 150 no ka hapa nui o ka wai, ka mahu a me nā paipu kemika maʻamau, ʻoiai ʻo ke kiʻekiʻe o ke kaomi ʻana e mālama i ka mahu kiʻekiʻe a me nā hiʻohiʻona hana petrochemical.

He aha nā mea maka maʻamau i hoʻohana ʻia no ka hana ʻana i nā ʻīpuka flanged?

Kohi ʻia ke kino valve a me nā mea wedge e like me ka waena a me ka mahana:

ʻO ke kila kalapona WCB: kā mākou koho nui, ikaika paʻa no ka ʻaila maʻamau, ka wai a me ka mahu

SS304 / SS316 kila kila: anti-corrosion, kūpono no ka wai kemika a me nā paipu wai kai.

ʻO ka hao maʻemaʻe: koho waiwai no nā ʻōnaehana wai maʻemaʻe o ke kūlanakauhale haʻahaʻa

Hoʻohui pū ʻia nā mea hoʻopili like ʻole: graphite packing no ka mahu wela kiʻekiʻe, RPTFE no nā media corrosive nāwaliwali, a me Stellite paʻa paʻa no nā maka hoʻopaʻa paʻa kiʻekiʻe.

He aha nā hana mālama i kēlā me kēia lā e pono ai mākou e hahai no Gate Valves Flanged End?

ʻO ka hana maʻamau maʻalahi hiki ke lōʻihi ka lōʻihi o kāu ʻīpuka.

E hōʻoia ʻoe e wehe piha a pani paha i ka valve, mai waiho i ka hapalua o ka wehe ʻana no ka mea e pau koke ke sila.

E nānā i nā bolts flange i kēlā me kēia mau mahina. E hoʻopaʻa i nā mea ʻokoʻa a hoʻololi i nā gaskets kahiko inā ʻike ʻoe i nā kahe a puni ka hui.

E kau i ka lubricant kūikawā ma ke kumu valve i kēia manawa a laila e huli mālie ka lima me ka ʻole o ka paʻa.

E hoʻomaʻemaʻe i ka lepo a me ka hoʻokumu ʻana o ke kemika ma waho o ka valve i waho e hoʻōki i ka hana ʻana o ka ʻōpala ma ke kino a me nā flanges.

Inā e kahe mau ka pahu i ka wā e paʻa pono ai, e hoʻokaʻawale iā ia no ka hoʻomaʻemaʻe ʻana a i ʻole ke kāʻei ʻana i nā wili a me nā noho sila.

Inā ʻaʻole hoʻohana ʻia ka valve no kekahi manawa, e waiho ʻia e hāmama loa a uhi i ke kumu e pale ai i ka ʻōpala a me ka lepo.
