Valve halamɔ gbɛi
1.Determine nitsumɔ shihilɛ ni yɔɔ valve lɛ mli lɛ taakɛ valve lɛ ni akɛtsuɔ nii yɛ tsɔne loo gbɛjianɔtoo paipii lɛ mli lɛ. Nɔkwɛmɔnɔ, nitsumɔ gbɛ, nitsumɔ nɔnyɛɛ kɛ nitsumɔ mli latsaa, kɛ ekrokomɛi.
2.Determine sealing nitsumɔ ŋwɛi gbɛhe ni ji valve lɛ taakɛ nitsumɔ gbɛ, nitsumɔ shihilɛ kɛ mɔ ni kɛtsuɔ nii lɛ taomɔ nii.
3.Kwɛmɔ valve henɔ kɛ tsɔne kudɔmɔ gbɛ lɛ taakɛ yiŋtoo ni yɔɔ valve lɛ sɛɛ. Henɔi tamɔŋmei valve ni nyɛɔ ehiɔ shi, kwɛmɔ valv, shinaa valv,valv ni akɛtoɔ he, kɛ ekrokomɛi. Kudɔmɔ gbɛ tamɔ ŋmei shwiili ŋmei, srawa hewalɛ, kɔɔyɔɔ, kɛ ekrokomɛi.
4.Taakɛ gbɛi paramita ni yɔɔ valve lɛ mli lɛ tsɔɔ lɛ. Akɛ valve lɛ mli hewalɛ ni ji nominal kɛ dalɛ ni ji nominal lɛ kɛ process paipi ni akɛwo mli lɛ kpãa gbee. Valve komɛi tsɔɔ bɔ ni valve lɛ dalɛ ji ha yɛ bɔ ni valve lɛ mli nu lɛ hoɔ loo ejɛɔ mli yɛ be ni ato he gbɛjianɔ lɛ mli lɛ naa.
5.Determine tsakpaa gbɛ ni yɔɔ valve naagbee hiɛ kɛ paipii lɛ taakɛ nitsumɔ shihilɛi diɛŋtsɛ kɛ nominal valve lɛ dalɛ. Tamɔ flange, welding, klip loo kpãa, kɛ ekrokomɛi.
6.Kwɛmɔ bɔ ni valve lɛ yɔɔ ha kɛ bɔ ni eyɔɔ ha lɛ yɛ he ni akɛwoɔ mli lɛ, he ni akɛwoɔ mli lɛ, kɛ valve lɛ dalɛ ni ji nominal lɛ naa. Tamɔ shinaa valv ni yɔɔ ediŋ, koŋ globe valv, bɔɔlu valv ni yɔɔ shiŋŋ, kɛ ekrokomɛi.
Taakɛ sui ni yɔɔ mli lɛ, nitsumɔ mli nɔnyɛɛ kɛ nitsumɔ mli latsaa lɛ tsɔɔ lɛ, kɛyashi valve lɛ shishi kɛ emli nibii lɛ ahalamɔ ni ja kɛ jwɛŋmɔ ni sa nɔ.
