ZF8006 Kūleʻa kila wahine swing check valve DN20

pale i ka mea waena o ka paipu mai ka kahe ʻana i hope.ʻO ka valve i wehe ʻia a pani ʻia paha nā ʻāpana e ka kahe a me ka ikaika o ka mea e pale aku ai i ke kahe ʻana i hope, ua kapa ʻia ʻo ia he valve check.Loaʻa i ka ʻāpana o nā valves ka nānā ʻana i nā valves, kahi i hoʻohana nui ʻia i nā pipeline kahi e kahe ai ka medium i hoʻokahi ʻaoʻao, a ʻae wale i ke kahe e kahe i ka ʻaoʻao hoʻokahi e pale ai i nā pōʻino.Pono e hoʻokomo ʻia kēia ʻano valve ma ke ʻano ākea ma ka pipeline.Hoʻohana ka swing check valve i ke kūkulu ʻia ʻana o ka rocker swing structure.Hoʻokomo ʻia nā ʻāpana wehe a pani ʻia o ka valve i loko o ke kino valve a ʻaʻole e komo i ke kino valve.Koe wale no ka sealing gasket a sealing apo ma ka waena flange, ka holoʻokoʻa ʻAʻohe wahi leakage, e pale ana i ka hiki ʻana o ka leakage valve.ʻO ka pilina ma waena o ka lima swing o ka swing check valve a me ka valve clack e hoʻohana i kahi hoʻopili pili spherical, i loaʻa i ka valve clack kekahi degere o ke kūʻokoʻa i loko o ka laulā o 360 degere, a aia kahi uku kūpono kūpono.Ua hoʻohana nui ʻia nā ʻōkuhi swing check ma nā kahua he nui e like me ka ʻoihana kemika, metallurgy, a me nā lāʻau lapaʻau.

ʻO ke ʻano a me nā ʻano o ka valve check:

1. He koho maikaʻi loa o nā mea hoʻopaʻa pahu pahu, e like me nā kūlana kūloko a me nā ʻāina ʻē, a me ke kūlana kiʻekiʻe o nā mea.

2. ʻO ka paʻa hoʻopaʻa ʻana o ka valve check ua holomua a kūpono.Hana ʻia ka ʻili o ka valve clack a me ka noho valve i ka hao a i ʻole stellite cobalt-based cemented carbide surfacing surface, nona ke kūpaʻa ʻaʻahu, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka corrosion a me ka pale ʻana.Maikaʻi a lōʻihi ke ola lawelawe.

3. Hoʻolālā ʻia a hana ʻia ka valve check e like me ke kūlana aupuni GB / T12235.

4. Hiki i ka valve check ke hoʻohana i nā kūlana flange piping like ʻole a me nā ʻano sealing flange e hoʻokō i nā pono ʻenekinia like ʻole a me nā koi o ka mea hoʻohana.

5. Hoʻopihaʻia ka mea kino valve o ka valve check, a hiki ke koho ponoʻia ka gasket e like me nā kūlana hana maoli a iʻole nā ​​koi o ka mea hoʻohana, a hiki ke kūpono i nāʻano kaomi, ka mahana a me nā kūlana hana.E like me nā koi o ka mea hoʻohana, hiki ke hoʻolālā ʻia a hana ʻia nā valve me nā ʻano hana like ʻole.

ʻO ka pahu hōʻoia e pili ana i ka valve e wehe 'akomi a pani i ka diski ma muli o ke kahe ʻana o ke kikowaena pono'ī, a hoʻohana ʻia e pale i ke kahe ʻana i hope.Ua kapa ʻia ʻo ia ka valve check, one-way valve, reverse flow valve, a me back pressure valve.ʻO ka valve check kahi ʻano valve aunoa, ʻo kāna hana nui ka pale ʻana i ke kahe hope o ka medium, pale i ka ʻōpala a me ka hoʻokele kaʻa mai ka hoʻohuli ʻana, a me ka hoʻokuʻu ʻana o ka medium container.Hiki ke hoʻohana ʻia nā kiwi hoʻopaʻa no ka hoʻolako ʻana i nā paipu no nā ʻōnaehana kōkua kahi e piʻi ai ke kaomi ma luna o ke kaomi ʻōnaehana.Hiki ke hoʻokaʻawale ʻia nā kiwi hoʻopaʻa i loko o nā kiwi hoʻopaʻa swing a me nā kiwi hoʻokiʻekiʻe.ʻO ka valve check he kūpono ia no nā pipeline o nāʻano hana likeʻole i kaʻaila, kemika, ka lāʻau lapaʻau, ka mea momona, a me nāʻoihana mana uila me ke kaomi o PN1.6 ~ 16.0MPa a me ka mahana hana o -29 ~ + 550 °.ʻO ka mea pili i ka wai, ka aila, ka mahu, Acidic medium, etc.

Wehe ʻia a pani ʻia ʻo Check valve e ka ikaika i hana ʻia e ke kahe ʻana o ka waena ponoʻī i loko o ka pipeline, a no ka valve aunoa.Hoʻohana ʻia ka valve check i ka ʻōnaehana paipu, a ʻo kāna hana nui ka pale ʻana i ke kahe mai ka hoʻi ʻana, e pale aku i ka hoʻohuli ʻana o ka paila a me kāna kaʻa kaʻa, a me ka hoʻokuʻu ʻana i ka medium i loko o ka ipu.Hiki ke hoʻohana ʻia ka valve check e hoʻolako i nā pipeline kahi e piʻi ai ke kaomi o ka ʻōnaehana kōkua ma luna o ke kaomi o ka ʻōnaehana nui.ʻO ka hana o ka valve check ka mea e pale aku ai i ke kahe ʻana o ka waena o ka pipeline.No ka ʻāpana o nā valve ʻakomi, e wehe a pani ʻakomi ʻia nā valves e ka ikaika o ke kahe kahe.Hoʻohana wale ʻia ka valve check i loko o ka pipeline kahi e kahe ai ka medium ma kahi ʻaoʻao e pale aku i ka hoʻi ʻana mai e pale i nā pōʻino.ʻO ke ala kūpono o ka valve check he wai, aila, mahu, acid medium, etc.
