Nibii Titrii ni kɔɔ Paipi Valve ni Akɛwoɔ Mli lɛ He

I. Hesaamɔ dani akɛwoɔ mli

1. Kwɛmɔ valve lɛ he mfoniri lɛ, bɔ ni eyɔɔ ha, kɛ bɔ ni nu lɛ hoɔ ehaa lɛ koni ona nɔmimaa akɛ eshɛɔ taomɔ nii ni akɛfee lɛ he.

2. Kwɛmɔ bɔ ni valve lɛ gbɔmɔtso lɛ mli ŋmei lɛ he tse ha ni ojie nibii ni buɔ mɔ he kɛ maŋsɛɛ nibii ni akɛwoɔ mli lɛ.

3. Ehe miihia ni afee butt welding tsakpaa valves lɛ kɛ ŋmeii, ni ehe miihia ni flange tsakpaa valves lɛ akwɛ bɔ ni sealing lɛ nɔ lɛ yeɔ emuu ha.

II. Gbɛtsɔɔmɔ ni akɛwoɔ mli lɛ nɔkwɛmɔ

1. Globo valve lɛ kɛŋwɛi ŋwɛi ŋwɛi valveesa akɛ akɛwo gbɛ ni gãimlibi ni yɔɔ valve lɛ gbɔmɔtso lɛ nɔ lɛ tsɔɔ lɛ nɔ pɛpɛɛpɛ.

2. Yɛ shishitoo mla naa lɛ, .stem valve ni teee shi, nu mli ŋmɔtɔ valve, ni abaanyɛ akɛ bɔɔlu valvɛi awo gbɛi enyɔ lɛ fɛɛ nɔ, shi esa akɛ agbala jwɛŋmɔ kɛya bɔ ni etsuɔ ​​nii ehaa lɛ nɔ.

3. Ehe miihia ni tsɔne ni akɛtswaa la / kɔɔyɔɔ lɛ ato he ko kɛha actuator nitsumɔ kɛ ekwɛmɔ.

III. Welding ni akɛwoɔ mli lɛ he saji

1. Esa akɛ agbele butt welding valve lɛ fã yɛ be mli ni atswaa lɛ koni akatsi nɔ ni hulutsoo ni fiteɔ lɛ kɛbaa lɛ naa.

2. Okɛ argon arc welding afee shishitoo lɛ, ni okwɛ ŋwɛi ŋta lɛ mli la lɛ nɔ koni ekaho ŋta ni ato he gbɛjianɔ yɛ valve lɛ mli lɛ he.

3. Kɛ́ atswa tsɔne lɛ sɛɛ lɛ, esa akɛ aka valve lɛ bɔ ni etsuɔ ​​nii ehaa koni ana akɛ egbeleɔ ni eŋmɛɔ bɔ ni sa.

IV. Nibii Titrii ni Kɔɔ Flange Kpãa He

1. Flange lɛ nɔ nibii ni akɛtswaa lɛ hiɔ shi yɛ he kome, ni sɛɛkuu ni fe fɛɛ ni aŋmɛ gbɛ lɛ hoɔ 0.15% yɛ flange lɛ kponɔgbɛ ŋwɛi ŋta lɛ he.

2. Esa akɛ akɛ gasket lɛ awo teŋgbɛ, ni atswa bolts lɛ shi jogbaŋŋ ni efee ekome, ni esa akɛ ashɛ torque ni ato he gbɛjianɔ lɛ he shii etɛ.

3. Esa akɛ atswa valves ni mli edɔ waa lɛ ahe tsɔnei ni kɛ amɛhe kpaa gbee lɛ shii enyɔ yɛ shihilɛ ni mli edɔ mli.

V. Nibii ni hi jogbaŋŋ lɛ anɔkwɛmɔ

1. Hewalɛ kaa kɛ sealing kaa he miihia yɛ be mli ni akɛwoɔ mli lɛ sɛɛ.

2. Kɛ́ oofɔ tsɔne lɛ mli lɛ, esa akɛ atsɔ valve ni kudɔɔ nu lɛ, flow meter kɛ nibii krokomɛi ahe.

3. Okɛ nibii ni akɛwoɔ mli lɛ awo mli, ni saji otii tamɔ valve lɛ he yibɔ, kaa mli hewalɛ, nitsumɔ torque, kɛ ekrokomɛi fata he.

Kaadi: Esaaa akɛ akɛ valve lɛ tsuɔ nii akɛ nɔ ni akɛfiɔ paipii lɛ sɛɛ. Valves wuji biɔ sɛɛfimɔ tsɔne ko ni yɔɔ srɔto. Kɛji akɛ akɛwo mli sɛɛ lɛ, esa akɛ valve lɛ ahi he ni agbe naa kwraa lɛ, ni abu he koni ekɛ cross-operation akafite.
