ʻO ka hoʻomaka ʻana i ka hoʻohana ʻana, nā mea nui a me nā hiʻohiʻona o ka wafer check valve

E nānā i ka valve e pili ana i ka valve e wehe 'akomi a pani ana i ka pahu valve ma o ka hilinai ana i ke kahe ana o ka medium ponoi iho e pale aku i ka backflow o ke ano.hoʻopaʻa pahu, kiwikā ala hoʻokahi, kiwi hoʻihoʻi a me ka pahu hoʻi.ʻO kahoʻopaʻa pahuʻO ia ka valve aunoa nona ka hana nui e pale aku i ka hoʻihoʻi ʻana o ka waena, ka hoʻohuli ʻana o ka paila a me ke kaʻa hoʻokele, a me ka hoʻokuʻu ʻana o ka medium i loko o ka ipu.Hiki ke hoʻohana ʻia nā kiwi hoʻopaʻa ma nā laina e hāʻawi ana i nā ʻōnaehana kōkua kahi e piʻi ai ke kaomi ma luna o ke kaomi ʻōnaehana.

1.Thoʻohana ʻo ia i ka pahu wafer check valve:

ʻO kahoʻopaʻa pahu ua hoʻokomo ʻia i loko o ka ʻōnaehana pipeline, a ʻo kāna hana nui ka pale ʻana i ka backflow o ka waena.ʻO kahoʻopaʻa pahuʻO ka valve ʻakomi i wehe ʻia a pani ʻia ma muli o ke kaomi waena.Wafer check valve he kūpono no ka kaomi inoa PN1.0MPa ~ 42.0MPa, Class150 ~ 25000;anawaena inoa DN15~1200mm, NPS1/2~48;Kaho hope waena.Ma ke koho ʻana i nā mea like ʻole, hiki ke hoʻopili ʻia i nā media like ʻole e like me ka wai, ka mahu, ka aila, ka waikawa nitric, ka waikawa acetic, ka medium oxidizing ikaika a me ka uric acid.

2.The mea nui o kawafer check valve:

Aia ke kila kalapona, ke kila wela haʻahaʻa, ke kila kila lua (F51/F55), ke kila titanium, ke keleawe aluminika, INCONEL, SS304, SS304L, SS316, SS316L, kila chrome molybdenum, Monel (400/500), 20 # alloy, Hastelloy a me nā mea metala ʻē aʻe.

3. Nā hiʻohiʻona hale o kawafer check valve:

A.He pōkole ka lōʻihi o ka hoʻolālā, a ʻo kona lōʻihi ka lōʻihi he 1/4 ~ 1/8 wale nō o ka pahu hoʻopaʻa flange maʻamau.

B.ʻO ka liʻiliʻi liʻiliʻi a me ke kaumaha māmā, ʻo 1/4 ~ 1/20 wale nō kona paona o ka valve check flange maʻamau

C.Paʻa koke ka disc valve a liʻiliʻi ke kaomi hāmare wai

D.Hiki ke hoʻohana ʻia nā paipu ākea a i ʻole nā ​​paipu kūpaʻa, maʻalahi e hoʻokomo

E.He maʻemaʻe ke kahawai kahe a liʻiliʻi ke kūpaʻa wai

F.ʻO ka hana koʻikoʻi a me ka hana sila maikaʻi

G.He pōkole ka hele ʻana o ka disc valve a he liʻiliʻi ka hopena hopena

H.He maʻalahi a paʻa ka hale holoʻokoʻa, a nani ke ʻano

I.ʻO ke ola lōʻihi a me ka hana hilinaʻi

4.TʻO nā hewa maʻamau o ka valve check:

A.Ua haki ka disc valve

ʻO ke kaomi o ka mea waena ma mua a ma hope o ka pahu loiloi i kahi kūlana kokoke i ke kaulike a me ka "saw".Paʻi pinepine ʻia ka disc valve me ka noho valve, a ua haki ka disc valve i hana ʻia me kekahi mau mea palupalu (e like me ka hao hao, keleawe, etc.).ʻO ke ʻano pale ʻana, ʻo ia ka hoʻohana ʻana i ka valve check me kahi disc ma ke ʻano he mea ductile.

B.Kaho hope waena

Ua poino ka ili hoailona;paʻa nā haumia.Ma ka hoʻoponopono ʻana i ka ʻili o ka sila a me ka hoʻomaʻemaʻe ʻana i nā mea haumia, hiki ke pale ʻia ka backflow.
