I. Hoʻokomo i ka valve
ʻO ka valve vacuum he mea hoʻohana ʻia e hoʻololi i ke ala o ka ea, hoʻoponopono i ka nui o ke kahe o ke kinoea, ʻoki a hoʻopili paha i ka pipeline i loko o ka ʻōnaehana vacuum.Hoʻopaʻa ʻia nā ʻāpana pani o ka valve vacuum e ka sila rubber a i ʻole ke sila metala.
II.ʻO nā hoʻohana ʻana i ka valve vacuum maʻamau.
ʻO nā pahu wai hoʻoheheʻe
Hoʻohana ʻia i loko o nā ʻōnaehana ʻōnaehana kiʻekiʻe a i ʻole kiʻekiʻe kiʻekiʻe i ka wā e pono e mālama ʻia ka ʻōpala i loko o kahi ʻōnaehana hoʻopaʻa ʻia.Hoʻohana ʻia nā ʻūhā ʻūhā e hoʻomalu i ke kahe ʻana o ka ea i loko o ke keʻena ʻawaʻawa, hoʻokaʻawale, hoʻoheheʻe, hāʻawi i ka hoʻemi ʻana a i ʻole ka hoʻokele mana.ʻO nā ʻīpuka puka, nā kīwaha Inline a me nā ʻāpana kihi ʻo ia nā ʻano maʻamau o nā kīwaha maʻemaʻe i hoʻohana ʻia no nā noi ʻūhā kiʻekiʻe a kiʻekiʻe paha.ʻO nā ʻano valve hou e pili ana i nā kiwi lele, nā kiwi hoʻoili, nā kiwi pōpō, nā kiwi pendulum, nā kiwi metala āpau, nā kiwi piha, nā kiwi alumini, nā kiwi kīwī i uhi ʻia me Teflon a me nā kiwi pololei.
ʻO nā kīwī pēpē
ʻO nā puʻupuʻu e wehe wikiwiki ana i loko o nā disc metala a i ʻole nā vanes e pivot ma nā kihi ʻākau i ke kuhikuhi o ke kahe ʻana i ka pipeline a i ka wā e hoʻohuli ai i ko lākou axis, hoʻopaʻa ka valve i ka noho ma ke kino valve.
Nā pahu hoʻololi (nā ʻīpuka ʻehā ʻehā)
ʻO nā kiwi hoʻokaʻawale kūpono no ka hoʻohana ʻana ma waena o nā keʻena haʻahaʻa i hoʻopaʻa ʻia a me nā keʻena hoʻololi, a ma waena o nā keʻena hoʻololi a me nā keʻena hana i nā lako hana semiconductor.
Nā Pahu Poepoe Vacuum
he hapaha huli pololei kahe me ka hui pani poepoe me na noho poepoe like no ke kaumaha o ka sila.
ʻO nā ʻūhā pendulum
He kiwi puʻupuʻu nui i hoʻokomo ʻia ma waena o ke keʻena ʻāwīwī kaʻina a me ka inlet pump turbomolecular.Hoʻolālā maʻamau ʻia kēia mau kīwaha pendulum vacuum e like me ka puka a i ʻole ka pendulum valves no nā noi e like me OLED, FPD a me nā ʻōnaehana hana ʻenehana PV.
ʻO nā pahu hao a pau
Hoʻolālā ʻia no ka hoʻohana ʻana i nā kaiapuni maloʻo ultra-kiʻekiʻe kahi e ʻae ʻole ai nā wela kiʻekiʻe i ka hoʻohana ʻana i nā elastomers a me nā metala gasket cryogenic.Hāʻawi nā kīwī metala āpau i hiki ke hoʻopaʻa ʻia i ka hoʻopaʻa ʻia ʻana o ka wela kiʻekiʻe mai ke kaomi lewa a ma lalo o 10-11 mbar.
ʻO nā pahu wai hoʻoheheʻe
E hana hilinaʻi ma nā ʻōnaehana hana semiconductor a me nā noi me nā kemika a me nā ʻōpala.Hiki iā lākou ke hoʻohana ʻia i loko o ka ʻawaʻawa ʻawaʻawa, ka ʻawaʻawa kiʻekiʻe a i ʻole nā wahi ʻūhā kiʻekiʻe kiʻekiʻe.
Aluminum huina kiwi
ʻO ka puka komo a me ka puka o kēia mau kiwi ma nā kihi ʻākau kekahi i kekahi.Hana ʻia kēia mau ʻāpana kihi i ka alumini A6061-T6 a hoʻohana ʻia i ka semiconductor a me nā mea hana mea hana, R&D a me nā ʻōnaehana ʻenehana no nā noi ʻana i ka ʻawaʻawa kiʻekiʻe.
ʻO ke kīpē kīwī i uhi ʻia ʻo Teflon he mea hoʻoheheʻe ʻia ʻo ia me kahi ʻāpana kūpaʻa kūpaʻa a me ke kemika.
III.ʻO nā hiʻohiʻona o nā kīʻaha hau.
Aia ka puʻe ma lalo o ke kaomi lewa a ʻaʻole hiki i ka hāʻule ke kaomi ma luna o ka flap valve ma mua o 1 kg ikaika/cm.ʻO ka mahana hana o ke kikowaena e pili ana i ke kaʻina hana o ka mea i hoʻohana ʻia.ʻAʻole ʻoi aku ka mahana ma mua o ka -70 ~ 150°C.ʻO ke koi nui loa no ia mau valve e hōʻoia i kahi kiʻekiʻe o ka paʻa o ka pilina a me ka denseness o ka hale a me nā mea gasket.
E like me ka puʻupuʻu puʻupuʻu māmā hiki ke maheleia i eha hui.
1) Haʻahaʻa haʻahaʻa vacuum kiwi: puʻe haʻahaʻa p=760~1 mmHg.
2) ʻAiʻa mānoanoa kiwi: p=1×10-3 mmHg.
3)Nā kiʻekiʻe kiʻekiʻe mānoanoa kiwi: p=1×10-4 ~1×10-7 mmHg.
4)Pūnaewele kiʻekiʻe kiʻekiʻe: p≤1×10-8 mmHg.
Ma ke ʻano he valve kaapuni paʻa me ke anawaena ma lalo o 250 mm, ʻo ke kumu i hoʻohana nui ʻia ʻo ia ka pahu hoʻopaʻa ʻia me ka neʻe laina.ʻO nā kīpē puka, ʻoi aku ka palena, akā no nā anawaena nui kēia.Loaʻa pū ʻia nā kiwi puʻupuʻu spherical (nā kiwi pōlele), nā kiwi puʻu a me nā kiwi lele.ʻAʻole i hoʻolaha ʻia nā kīwī hoʻopili no nā ʻūhā ʻūhā no ka mea makemake lākou i ka lubrication aila, e hiki ai i ka mahu aila ke komo i loko o ka ʻōnaehana hoʻoheheʻe, ʻaʻole i ʻae ʻia.Hiki ke hoʻokele lima ʻia nā kiwi uila me ka lima a me ka mamao ma ke kula, a me ka uila, electromagnetically (solenoid valves), pneumatically a hydraulically.
