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

Waferpapa pāluahoʻopaʻa pahue pili ana i ka valve e wehe 'akomi ana a pani i ka pahu valve ma ka hilinai ana i ke kahe ana o ka medium ponoi e pale aku i ka backflow o ka medium, i ikeia hoi he check valve, one-way valve, reverse flow valve and back pressure valve.Waferpapa pāluahoʻopaʻa pahuʻO ia ka valve aunoa nona ka hana nui e pale aku i ka hoʻihoʻi ʻana o ka waena, e pale i ka hoʻohuli ʻana o ka paila a me ke kaʻa hoʻokele, a hoʻokuʻu i ka mea waena i loko o ka ipu.Waferpapa pāluaHiki ke hoʻohana ʻia nā ʻōkuhi nānā ma nā laina e hāʻawi ana i nā ʻōnaehana kōkua kahi e piʻi ai ke kaomi ma luna o ke kaomi ʻōnaehana.

1. Wafer 'ano papalua papa kuhikuhi valve noi:

Waferpapa pāluahoʻopaʻa pahuua hoʻokomo ʻia i loko o ka ʻōnaehana pipeline, a ʻo kāna hana nui ka pale ʻana i ka backflow o ka waena.ʻO ka waferpapa pāluahoʻopaʻa pahuʻO ka valve ʻakomi i wehe ʻia a pani ʻia ma muli o ke kaomi waena.ʻAno-waferpapa pāluahoʻopaʻa pahuhe kūpono no ka kaomi inoa PN1.0MPa ~ 42.0MPa, Class150 ~ 25000;anawaena inoa DN15~1200mm, NPS1/2~48;ka mahana hana -196 ~ 540 ℃ ma nā paipu like ʻole, hoʻohana ʻia e pale i ka hoʻihoʻi ʻana o ka 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. ʻO ka mea nui o ka waferpapa pāluahoʻopaʻa pahu:

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 o ka halepapa pāluahoʻopaʻa pahu:

1. He pōkole ka lōʻihi lōʻihi, a ʻo kona lōʻihi lōʻihi he 1/4 ~ 1/8 wale nō o ka flanged kuʻuna.kowalihoʻopaʻa pahu.

2. ʻO ka liʻiliʻi liʻiliʻi a me ke kaumaha māmā, ʻo kona kaumaha he 1/4 ~ 1/20 wale nō o ka flanged kuʻuna.kowalihoʻopaʻa pahu.

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

4. Hiki ke hoʻohana ʻia nā paipu ʻelua a i ʻole nā ​​paipu kūpaʻa, maʻalahi ke hoʻouka

5. He maʻalahi ke kahawai kahe a he liʻiliʻi ke kū'ē o ka wai

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

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

8. He maʻalahi a paʻa ka hoʻolālā holoʻokoʻa, a nani ke ʻano

9. ʻO ke ola lōʻihi a me ka hana hilinaʻi

ʻO ka hā, nā hewa maʻamau o kapapa pāluaʻO ka valve nānā:

1. Ua haki ka disc valve

ʻO ke kaomi o ka mea waena ma mua a ma hope o kapapa pāluahoʻopaʻa pahuaia i loko o kahi kūlana kūlike a me ka "saw".Paʻi pinepine ʻia ka disc valve me ka noho valve, a ua hahau ʻia ka disc valve i hana ʻia me kekahi mau mea palupalu (e like me ka hao hao, keleawe, etc.).hakihaki.

ʻO ke ala pale e hoʻohana apapa pāluae nānā i ka valve me kahi diski ma ke ʻano he mea ductile.

2. 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.
