Hoʻokaʻawale ʻia ke ʻano o ka pōlele i ka ʻano lana a me ke ʻano paʻa

Paʻa kinipōpō paʻa

Aia ma lalo o ke kīpē e hoʻoponopono ai i ka pōlele. Aia ma ka waena ka pahu kinipopo. Aia kekahi ʻōpuʻu valve ma nā ʻaoʻao luna a lalo e hoʻopaʻa i ka pōleʻa i waena. Mai waho mai, ʻo ka mea maʻamau, ʻo ka pahu pōpō me kahi wahi kākoʻo diski ma lalo o ka pahu pōpō he pahu pōpō paʻa.

Puka kinipopo lana

E lana ana ka poepoe ma ka waena, a aohe wahi kokua malalo iho he pahu kinipopo lana

ʻO ke anawaena kiʻekiʻe loa o ka pahu pōpō e lana ana ʻo DN250

Hiki ke DN1200 ke anawaena kiʻekiʻe o ka valve pōpō paʻa

ʻO ka ʻokoʻa nui ma waena o nā kiwi pōpō paʻa a lana ʻana aia i ka hoʻopaʻa ʻana o ka pōpō waena. Hoʻopōʻino ka hoʻopaʻa ʻana i ke sila. ʻO keʻano paʻa e hoʻonui i ke ola lawelawe o ka valve ball. ʻOi aku ka lōʻihi o ka lawelawe ʻana o ka valve pōpō paʻa ma mua o ka valve pōpō lana. E lana ana ka poepoe o ke ano poepoe a kawili i loko o ka lua, kahi e lana ai ka sila a poho. Ke kaʻawili ʻana o ka pōlele, ʻokoʻa nā kiko koʻikoʻi. Inā ʻaʻohe wahi kākoʻo, e hōʻino ia i ka sila ma nā ʻaoʻao ʻelua. I ka wā e hoʻohana ʻia ai ka valve pōleʻa, e hana ia i kekahi mau degere like ʻole o ka nalo puʻe. Ke loaʻa kahi kiko kākoʻo o ka pōleʻa, ʻaʻole ia e hoʻoemi i ke kaomi a i ʻole e liʻiliʻi loa ka ʻili o ke kaomi, no laila ʻoi aku ka lōʻihi o ke ola o ka pahu pōpō paʻa ma mua o ke ʻano lana. , 'Oi aku ka maika'i o ka ho'ohana 'ana i ka valve pōpō pa'a i kekahi mau manawa me ke alapine ho'ololi ki'eki'e.

Puka kinipōpōsila ana

Loaʻa i nā kiwi pōʻalo he ʻōpuʻu kinipopo V-like, nā kiwi pōpō hapalua eccentric,ʻO nā kiwi pōpō PVC, etc.

ʻO kēia nā valves like ʻole i kuhikuhi ʻia e like me nā manawa like ʻole

ʻano V ʻano kinipōpō pōkā

ʻO ke kahe kahe o ka pahu pōpō V-like he pahu pōlele me kahi awa V ʻoki ʻia, ʻo ia ka valve pōpō paʻa

Ka nui o ka noi: Ua hana kūikawā ʻia ke awa V. He ʻoki ʻo ia me ka ʻano V. E like me ka pahi, ʻo kāna hana ʻo ke ʻoki ʻana i kekahi mau kaula. No kekahi mau ʻāpana paʻa, e ʻoki pololei ʻia. ʻOkoʻa nō hoʻi ke ʻano o ka hana ʻana i ke kinipōpō. ʻOi aku ka nui o kekahi mau hale hana i ka wai a i ʻole nā ​​​​mea paʻakikī paʻakikī, e like me kēia ʻano ʻano V-like ball valve i hoʻohana pinepine ʻia.

ʻĀpana pōpoʻi hapa eccentric

ʻO ka valve hemispherical eccentric e like me ka valve pōpō V. He hapalua wale ke kumu o ka valve, a he pahu kinipopo paa no hoi. Hoʻohana nui ʻia no nā ʻāpana paʻa. Hoʻohana ʻia nā kiwi pōpō paʻa paʻa a pau i nā kiwi hemispherical eccentric. Hoʻohana nui nā mea kanu sima i kēia.

ʻO ka pahu kinipōpō V-like a me ka valve semi-ball eccentric he unidirectional a hiki ke kahe wale i ka ʻaoʻao hoʻokahi, ʻaʻole ke kahe bidirectional, no ka mea, ua hoʻopaʻa ʻia kona pōpō ma kekahi ʻaoʻao, a ʻaʻole paʻa ka sila ke kuʻi ʻia e ka ʻaoʻao hope, akā kahe wale nō ma kahi ʻaoʻao. E koʻikoʻi ka hoʻopaʻa ʻana i ke kaomi ʻana.

Puka kinipopo PVC

Na sila oʻO nā kiwi PVChe EPDM wale nō (ethylene propylene diene monomer), FPM (fluorine rubber)

ʻO ka pahu pōpō sila paʻa

He hiʻohiʻona kūikawā ko ke sila paʻa

Aia kekahi pūnāwai ma hope o ka noho valve sila paʻakikī, no ka mea, inā pili pono ka noho valve sila paʻa a me ka pōleʻa, ʻaʻole ia e hoʻololi. Ke hoʻopili ʻia ka pūnāwai ma hope o ka noho valve, e maʻalahi ka pōleʻa i ka wā o ka hoʻololi ʻana, no ka mea, ʻo ke sila paʻakikī ʻO ka pilikia e hoʻoholo ʻia ʻo ia ka hiki ke hana maʻamau ka pōleʻa, akā e ʻānai pinepine ʻia ka pōleʻa e ka mea waena. Inā paʻa kekahi mau ʻāpana i ka sila noho valve, ʻaʻole hiki ke hoʻohana ʻia. No laila, hiki ke kikoo iki a pili i ka paakiki o ka poepoe e kikoo ai. Inā he sila palupalu, inā paʻa nā ʻāpana i ka sila, e pōʻino pololei ka valve ke pani ʻia. ʻO ka sila paʻakikī e like me ka pahu pōpō V-like ma mua o ka haʻalele ʻana i ka hale hana me ka S60 i luna. Ua paakiki ka sila a me ka poepoe, no laila he mau mea paakiki. ʻAʻole ia e haki inā ʻoki liʻiliʻi ʻoe

Sila PPL

ʻO ka sila pū kekahi mea PPL, ua hoʻonui ʻia kona inoa ʻo PTFE, ʻo ka mea maka he polytetrafluoroethylene, akā ua hoʻohui ʻia kekahi graphite e hoʻohuli iā ia i ke kūpaʻa wela kiʻekiʻe, hiki i ka wela kiʻekiʻe ke piʻi i 300 ° (ʻaʻole kū lōʻihi i ka 300 ° High. wela), ʻo 250° ka mahana maʻamau. Inā makemake ʻoe i kahi manawa lōʻihi o 300 °, pono ʻoe e koho i kahi pahu pōpō sila paʻakikī. ʻO ke kūpaʻa wela kiʻekiʻe maʻamau o ka sila paʻakikī hiki ke hiki i 450 °, a hiki i ka wela kiʻekiʻe ke hiki i 500 °.
