1.Working medium

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

2.Working kaomi a me ka mahana

kiwi lele lelepono e hana maʻamau i loko o ke kaomi hana i kuhikuhi ʻia a me ke ʻano wela, no laila pono e koho i nā mea me ka ikaika kūpono a me ke kūpaʻa wela.

3. Nā kūlana kaiapuni

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

4.Valve kino mea

Nā mea kino valve opāpū lele lelee komo pū me ka hao hina hina, ka hao ductile, ke kila kila, ke kila kila, a pēlā aku. Inā ma kahi haʻahaʻa haʻahaʻa haʻahaʻa, hiki ke hoʻohālikelike ʻia ka hana o ka mea hao ductile me ka mea kila kila, a ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka hoʻohana ʻana i ka mea hao ductile.

5.Valve noho mea

Nā mea noho okiwi lele lelee komo pū me ka lāʻau lapaʻau a me nā fluoroplastics. Hiki ke hoʻohana ʻia nā noho kīpē Rubber i loko o nā media acidic nāwaliwali a me ka alkaline e like me ka wai, ka mahu, a me ka ʻaila, me ka hana sila ʻana maikaʻi; Hoʻohana ʻia nā noho valve fluoroplastic i loko o ka media corrosive loa.

6. Mea hoʻoheheʻe pepeke

Loaʻa ka hao ductile a me ke kila kuhili i nā mea ʻenehana butterfly disc no nā valve butterfly manual. I kekahi manawa, i mea e hoʻololi ai i nā kaiapuni media ʻoi aku ka paʻakikī, pono ia e wahī i ka disc butterfly me ke kāpili a i ʻole ka mea PTFE.

7.Valve kumu kumu mea

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

8.Drive mea

ʻElua mau ʻano hana lima lima nui, ʻo ka ʻau a me ka worm gear. ʻO nā mea paʻa ka nui o ka hao hao, ke kila kalapona, ke kila kila, ke alumini alumini, a pēlā aku; ʻO ka nui o nā mea o ke poʻo worm gear he hao.

I ka hōʻuluʻulu ʻana, ke koho ʻana i ka maikaʻi o nā meakīwī pēpē limaPono e noʻonoʻo pono i nā mea e like me ke ʻano hana, ke kaomi hana a me ka mahana, nā kūlana kaiapuni, a me nā mea hana o ke kino valve, noho valve, disc butterfly, a me ka valve shaft. Hiki i ke koho mea pono ke hōʻoia i ka hana maʻamau a me ke ola lawelawe okiwi lele wai.
