Nɔ ni ji enyɔ lɛ, nitsumɔ mli kaa ni yɔɔ mli lɛvalv
1. Hefɛo kɛ logo lɛ mlikwɛmɔ
(1) Nɔ ni yɔɔ mli lɛ mlikwɛmɔ: kɛji akɛ tɔmɔi komɛi yɛ bɔ ni valve lɛ yɔɔ ha lɛ mli, tamɔ ŋmeii, ŋmeii, ŋmeii, kɛ ekrokomɛi; Kwɛmɔ akɛ okadii, gbɛi, kɛ nibii ni akɛgbeɔ naa lɛ kɛ taomɔ nii lɛ kpãa gbee. (2) Mlai: Majimaji ateŋ mlai ni fata he ji API598, ASMEB16.34, ISO 5208, kɛ ekrokomɛi; 12224 (nibii ni he hiaa kɛha dade valves), GB/T 12237 (dade bɔɔlu valves kɛha petroleum, petrochemical kɛ nitsumɔhei ni kɔɔ he), kɛ ekrokomɛi. gbɛi wolo lɛ nɔ saji lɛ ja.
2. Dimensional susumɔ
(1) Nɔ ni yɔɔ mli ni akwɛɔ mli: Susumɔ valve lɛ mli nibii titrii lɛ ahe, ni nɔ ni fata he ji he ni akɛtswaa lɛ, valve lɛ gbɔmɔtso lɛ kɛlɛ, valve lɛ shishigbɛ ŋwɛigbɛ, kɛ ekrokomɛi, koni ona nɔmimaa akɛ eshɛɔ taomɔ nii ni yɔɔ tsɔne lɛ he mfonirii kɛ shishitoo mlai lɛ amli lɛ ahe. (2) Mlai: Majimaji ateŋ mlai ni fata he ji ASMEB16.10, ASME B16.5, ISO 5752, kɛ ekrokomɛi; Chinese mlai lɛ ekomɛi ji GB/T 12221 (valve lɛ shishitoo mlai lɛ alɛɛmɔ), GB/T 9112 (flange lɛ tsakpaa lɛ dalɛ), kɛ ekrokomɛi (3) Kaa gbɛ: Okɛ calipers, micrometers kɛ nibii krokomɛi ni akɛsusuɔ nii ahe lɛ atsu nii ni okɛsusu valve lɛ shishitoo mlai titrii lɛ ahe koni ona nɔmimaa akɛ eshɛɔ tsɔne lɛ he taomɔ nii lɛ ahe.

3. Sealing nitsumɔ kaa
(1) Static pressure kaa: okɛ hydrostatic pressure loo static pressure awo valve lɛ nɔ, ni okwɛ bɔ ni nu lɛ hoɔ ehaa yɛ be mli ni okwɛ nɔ be pɔtɛɛ ko sɛɛ. (2) Kɔɔyɔɔ ni mli wa fioo lɛ he kaa: Kɛ́ agbe valve lɛ naa lɛ, akɛ kɔɔyɔɔ ni mli wa fioo woɔ valve lɛ mli ni akwɛɔ bɔ ni kɔɔyɔɔ lɛ miiho. (3) Shia hewalɛ kaa: okɛ hydrostatic pressure ni nɔ kwɔ fe nitsumɔ hewalɛ lɛ awo valve lɛ nɔ koni oka eshia hewalɛ kɛ hewalɛ ni ekɛteɔ shi ewoɔ hewalɛ lɛ okwɛ. (4) Stem Hewalɛ Kasemɔ: Kwɛmɔ kɛji torque loo tensile hewalɛ ni stem lɛ naa yɛ be mli ni etsuɔ ​​nii lɛ yɛ he ko ni yɔɔ shweshweeshwe.
4. Nitsumɔ mli nifeemɔ he kaa
(1) Gbelemɔ kɛ naagbee torque kɛ oyaiyeli kaa: kaa gbelemɔ kɛ naagbee torque, gbelemɔ kɛ naagbee oyaiyeli kɛ nitsumɔ henumɔ ni yɔɔ valve lɛ mli lɛ okwɛ koni ona nɔmimaa akɛ etsuɔ ​​nii jogbaŋŋ ni eyɛ torque ni sa mli. (2) Kaa bɔ ni nu lɛ hoɔ ehaa lɛ: kaa bɔ ni valve lɛ hoɔ ehaa yɛ gbɛi srɔtoi anɔ koni ona nyɛmɔ ni eyɔɔ ni ekɛbaakwɛ nu lɛ nɔ.
5. Kaa ni haa mɔ he jɔ̃ɔ ehe
(1) Nɔ ni yɔɔ mli lɛ mlipɛimɔ: akwɛ bɔ ni valve nibii lɛ nyɛɔ amɛfiteɔ nibii ni akɛtsuɔ nii lɛ. (2) Mlai: Majimaji ateŋ mlai ni fata he ji ISO 9227 (salt spray test), ASTM G85, kɛ ekrokomɛi (3) Gbɛ ni atsɔɔ nɔ akaa: Akɛ valve lɛ woɔ salt spray kaa tsu ko mli koni akɛkase shihilɛ ni fiteɔ nii lɛ, ni akɛka bɔ ni nibii lɛ baanyɛ ahi shi yɛ shihilɛi ni fiteɔ nii amli lɛ akwɛ.
6. He ni anyɛɔ akɛ he fɔ̃ɔ nɔ lɛ he kaa
(1) Akwɛɔ bɔ ni agbeleɔ kɛ agbeɔ naa shii abɔ: Afeɔ valve lɛ nɔ shii abɔ koni akɛkwɛ bɔ ni ehiɔ shi ehaa kɛ bɔ ni anyɛɔ akɛ he fɔ̃ɔ enɔ kɛji akɛ akɛtsu nii be kakadaŋŋ. (2) Temperature stability test: kaa bɔ ni valve lɛ tsuɔ nii ehaa lɛ yɛ hulutsoo shihilɛi srɔtoi amli koni ona nɔmimaa akɛ etsuɔ ​​nii jogbaŋŋ yɛ shihilɛi ni mli edɔ waa lɛ amli. (3) Vibration kɛ shock kaa: Okɛ valve lɛ awo okpɔlɔ ni hosoɔ loo impact okpɔlɔ nɔ koni okɛkase vibration kɛ shock ni yɔɔ nitsumɔhe lɛ ni oka bɔ ni valve lɛ damɔ shi shiŋŋ kɛ bɔ ni anyɛɔ akɛ he fɔ̃ɔ enɔ lɛ okwɛ.
7. Leak ni anaa
(1) Mligbɛ leak detection: kaa mligbɛ sealing nitsumɔ ni yɔɔvalvyɛ shihilɛ ni agbe naa lɛ mli. (2) Kpojiaŋ nibii ni hoɔ lɛ anaa: kwɛmɔ bɔ ni kponɔgbɛ tsɔne lɛ mli wa havalvni akɛtsuɔ nii koni akɛkwɛ akɛ tsɔne ko ni hoɔ yɛ teŋgbɛ lɛ bɛ.
