1.Mea hana

Wahi a nā ʻano hana like ʻole, pono e koho i nā mea me ke kūpaʻa maikaʻi i ka pala. No ka laʻana, inā he wai paʻakai a wai kai paha ke ʻano, hiki ke koho ʻia ka disc valve alumini keleawe; Inā he waikawa ikaika a alkali paha ke ʻano, hiki ke koho ʻia ka tetrafluoroethylene a i ʻole ka fluororubber kūikawā ma ke ʻano he mea no ka noho valve.

2. Kaomi hana a me ka mahana

kiwikā pepeke sila laholiopono e hana maʻamau i loko o ke kaomi hana a me ka mahana i kuhikuhi ʻia, no laila pono e koho i nā mea me ka ikaika kūpono a me ke kūpaʻa wela.

3. Nā kūlana o ke kaiapuni

E noʻonoʻo i nā kūlana o ke kaiapuni kahi i loaʻa ai ka valve, e like me ka haʻahaʻa, ka paʻakai paʻakai, a me nā mea ʻē aʻe, a koho i ka mea kūpono. 

4. Mea kino Valve

ʻO nā mea hana o ke kino valve okiwikā pulelehua flangee komo pū me ka hao hoʻolei hina, ka hao ductile, ke kila hoʻolei, ke kila kila, a pēlā aku. I waena o lākou, ʻo ke kila kila ka hana maikaʻi loa, akā kiʻekiʻe ke kumukūʻai. Inā aia i loko o kahi kaiapuni haʻahaʻa, hiki ke hoʻohālikelike ʻia ka hana o ka mea hao ductile me ko ka mea kila i hoʻolei ʻia, a ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka hoʻohana ʻana i ka mea hao ductile.

5. Mea noho Valve

ʻO nā mea noho okiwikā pulelehua kapa iloe hoʻokomo i ka laholio a me nā fluoroplastics. Hiki ke hoʻohana ʻia nā noho valve laholio i nā media waikawa nāwaliwali a me ka alkaline e like me ka wai, ka mahu, a me ka ʻaila, me ka hana sila maikaʻi; Hoʻohana ʻia nā noho valve Fluoroplastic i nā media corrosive kiʻekiʻe.

6. Mea disc pulelehua

ʻO nā mea hana disc butterfly no nā valves butterfly manual e pili ana i ka hao ductile a me ke kila kila. I kekahi manawa, i mea e hoʻololi ai i nā kaiapuni media paʻakikī, pono e kāʻei i ka disc butterfly me ke kāpili a i ʻole ka mea PTFE.

7. Mea hana ʻauʻau Valve

ʻO ka hapa nui o lākou ua hana ʻia i ke kila kila, a hiki ke hoʻopilikino ʻia nā kūlana kūikawā e like me nā pono.

8. Mea hoʻokele

ʻElua mau ʻano hana lima nui, ka lima a me ke kapa ilo. ʻO nā mea hana lima e komo pū me ka hao hoʻolei, ke kila kalapona, ke kila kila, ka hui alumini, a pēlā aku; ʻO ka mea o ke poʻo kapa ilo he hao hoʻolei nui.

I ka pōkole, ke koho ʻana i ka maikaʻi o ka meakiwikā pulelehua manualpono e noʻonoʻo pono i nā mea e like me ka hana waena, ke kaomi hana a me ka mahana, nā kūlana o ke kaiapuni, a me nā mea o ke kino valve, ka noho valve, ka disc butterfly, a me ke koʻokoʻo valve. ʻO ke koho pono ʻana i nā mea hiki ke hōʻoia i ka hana maʻamau a me ke ola lawelawe okiwikā pepeke wai.
