Hoʻopōʻino pinepine ʻia ka ʻili sila o ka valve, hoʻopau ʻia a ʻaʻahu ʻia e ka medium, no laila he ʻāpana ia e hōʻino maʻalahi ʻia ma ka valve. E like me ka pneumatic ball valve a me ka electric butterfly valve a me nā valves ʻakomi ʻē aʻe, ma muli o ka wehe pinepine a me ka pani ʻana, ua hoʻopilikia pololei ʻia ko lākou maikaʻi a me ke ola lawelawe. ʻO ke koi kumu o ka ʻili sila valve, hiki i ka valve ke hōʻoia i ka sila palekana a hilinaʻi ma lalo o nā kūlana hana i kuhikuhi ʻia. No laila, pono i ka mea o ka ʻili ke loaʻa nā hiʻohiʻona penei:
(1) Hana sila maikaʻi, ʻo ia hoʻi, pono e hiki i ka ʻili sila ke pale i ka leakage o ka medium;
(2) Loaʻa iā ia kekahi ikaika, pono e hiki i ka ʻili sila ke kū i ke kumukūʻai kaomi kikoʻī o ke sila ʻana i hoʻokumu ʻia e ka ʻokoʻa kaomi waena;
(3) Ke kūpaʻa ʻana i ka palaho, ma lalo o ka lawelawe lōʻihi o ka mea ʻawaʻawa a me ke kaumaha, pono ka ʻili sila e kūpaʻa i ka palaho ikaika e kūlike me nā koi hoʻolālā;
(4) ʻO ka hiki ke kū'ē i nā ʻōpala, he mau sila ikaika nā sila āpau o ka valve, a aia ka friction ma waena o ke sila ʻana i ka wā o ka wehe ʻana a me ke kaʻina hana pani;
(5) Ke kū'ē i ka ʻino, pono e hiki i ka ʻili sila ke kū'ē i ka ʻino o nā mea pāpaho wikiwiki a me ke kuʻi ʻana o nā ʻāpana paʻa;
(6) Paʻa maikaʻi ka wela, pono ka ʻili sila e lawa ka ikaika a me ke kūpaʻa oxidation i ka mahana kiʻekiʻe, a pono e loaʻa ka pale anu maikaʻi i ka mahana haʻahaʻa;
(7) Hana maikaʻi ka hana ʻana, maʻalahi ke hana a mālama, hoʻohana ʻia ka valve ma ke ʻano he ʻāpana hana maʻamau, a ua hōʻoia ʻia he waiwai waiwai.
ʻO nā kūlana hoʻohana a me nā loina koho o nā mea ʻili sila valve. Ua māhele ʻia nā mea ʻili sila i ʻelua mau ʻāpana: metala a me ka mea ʻole metala. ʻO nā kūlana pili o nā mea i hoʻohana pinepine ʻia penei:
(1) Laho. Hoʻohana nui ʻia ia no ke kūlana sila o nā kiwikā puka paʻa haʻahaʻa haʻahaʻa, nā kiwikā diaphragm, nā kiwikā pepeke, nā kiwikā nānā a me nā kiwikā ʻē aʻe.
(2) Palakiko. ʻO nā palakiko i hoʻohana ʻia no ka ʻili sila he nylon a me PTFE, nona nā ʻano o ke kūpaʻa maikaʻi i ka palaho a me ke koina friction liʻiliʻi.
(3) Babbitt. ʻIke ʻia hoʻi ʻo ia he mea hoʻohuihui bearing, he kūpaʻa maikaʻi kona i ka pala a me ka hiki ke holo maikaʻi. He kūpono ia no ka ʻili sila o ka valve pani no ka ammonia me ke kaomi haʻahaʻa a me ka mahana o -70-150 ℃.
(4) Mea hoʻohuihui keleawe. Loaʻa iā ia ke kūpaʻa maikaʻi i ka ʻaʻahu a me kekahi kūpaʻa wela. He kūpono ia no ka valve honua, ka valve puka hao i hoʻolei ʻia a me ka valve nānā, a pēlā aku. Hoʻohana nui ʻia no ka wai a me ka mahu me ke kaomi haʻahaʻa a me ka mahana ʻaʻole i ʻoi aku ma mua o 200℃.
(5) Ke kila kila nikala-chrome. Loaʻa iā ia ke kūpaʻa maikaʻi i ka pala, ka pale ʻana i ka ʻino a me ke kūpaʻa wela. Kūpono no nā mea hana e like me ka waikawa nitric vapor.
(6) Ke kila kila kila. Loaʻa iā ia ke kūpaʻa maikaʻi i ka pala a hoʻohana pinepine ʻia i nā kiwikā me ke kaomi kiʻekiʻe a me ka mahana ʻaʻole i ʻoi aku ma mua o 450 ℃ no ka ʻaila, ka mahu wai a me nā mea ʻē aʻe.
(7) Ke kila kila chromium kiʻekiʻe. Loaʻa iā ia ke kūpaʻa maikaʻi i ka pala a me ka hana paʻakikī, a kūpono no ke kaomi kiʻekiʻe, ka ʻaila wela kiʻekiʻe, ka mahu a me nā mea hana ʻē aʻe.
(8) Ke kila nitrided. Loaʻa iā ia ke kūpaʻa maikaʻi i ka pala a me ke kūpaʻa i ka ʻōpala, a hoʻohana pinepine ʻia i nā kiwikā puka o ke kahua mana wela. Hiki ke koho ʻia kēia mea no ka poepoe o nā kiwikā pōpō paʻa.
(9) Carbide. Loaʻa iā ia nā waiwai piha maikaʻi e like me ke kūpaʻa ʻana i ka pala, ke kūpaʻa ʻana i ka ʻino a me ke kūpaʻa ʻana i ka ʻōpala, a he ola lawelawe lōʻihi. He mea sila kūpono ia. ʻO nā electrodes surfacing alloy tungsten i hoʻohana pinepine ʻia a me nā electrodes surfacing base drill, a pēlā aku, hiki ke hana i kahi sila wela kiʻekiʻe loa, kūpono no ka ʻaila, ka ʻaila, ke kinoea, ka hydrogen a me nā mea ʻē aʻe.
(10) Mea hoʻoheheʻe ʻia me ka pīpī. Aia nā mea hoʻoheheʻe cobalt, nā mea hoʻoheheʻe nickel, a me nā mea hoʻoheheʻe ʻauwae, nona ke kūpaʻa maikaʻi i ka pala a me ke kūpaʻa ʻana i ka ʻaʻahu.
I mea e hōʻoia ai i ka palekana a me ka hilinaʻi o ke sila valve, pono e hoʻoholo ʻia ka mea i koho ʻia e like me nā kūlana hana kikoʻī. Inā he ʻino loa ka medium, i ke koho ʻana i nā mea, pono e hoʻokō mua i ka hana corrosive, a laila e hoʻokō i nā koi o nā waiwai ʻē aʻe; Pono e hoʻolohe ka sila o ka valve puka i ke kūpaʻa maikaʻi; ʻO nā valve palekana, nā valve throttle a me ka valve hoʻoponopono e maʻalahi ke hoʻopau ʻia e ka medium, a pono e koho i nā mea me ke kūpaʻa corrosion maikaʻi; No ke ʻano inlaid o ke apo sila a me ke kino, pono e noʻonoʻo ʻia nā mea me ka paʻakikī kiʻekiʻe e like me ka ʻili sila; Pono nā valve laulā me ka mahana haʻahaʻa a me ke kaomi e koho i ka rubber a me ka plastic me ka hana sila maikaʻi e like me ke sila ʻana; I ke koho ʻana i ka mea sila, pono e hoʻomaopopo ʻia ʻoi aku ka paʻakikī o ka ʻili o ka noho valve ma mua o ka ʻili sila o ka disc valve.
