Waferpapa pāluahoʻopaʻa pahue pili ana i ka valve e wehe 'akomi a pani ana i ka pahu valve ma ka hilinai ana i ke kahe ana o ka medium ponoi iho 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 ke pale 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 pahuua kūpono no ka helu kaomi 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 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.
