I. Shishitoo Mlai Kɛha HalamɔKpɔŋɔi Valves
1. Gbɛjianɔtoo henɔ halamɔ
Akpɔlɔ teŋ valve (teŋ line henɔ):Valve stem kɛ butterfly disc lɛ ji nɔ ni yɔɔ teŋgbɛ, ni eyɛ mlɛo ni ejara hu waaa. Nɔ ni akɛfiɔ naa lɛ damɔ rɔba ni yɔɔ blɛoo nɔ. Ehi kɛha bei ni hulutsoo kɛ hulutsoo be ni sa yɔɔ mli, ni taomɔ nii ni mli wa bɛ mli.
Valve kome ni yɔɔ srɔto:Akɛ valve stem lɛ jeɔ ŋmei diski lɛ teŋgbɛ, ni ehaa gbeekpamɔ ni yɔɔ ŋwɛi ŋtayaai lɛ ateŋ lɛ baa shi yɛ be mli ni etsuɔ nii lɛ, ni ehaa sɛɛfimɔ wala yaa hiɛ. Ehi jogbaŋŋ kɛha nitsumɔi ni yɔɔ teŋgbɛ kɛ nɔ ni baa shi ni biɔ ni agbele ni agbe naa shii abɔ lɛ.
Kɔɔyɔŋtsere valve ni yɔɔ srɔto enyɔ (kɔɔyɔŋtsere valve ni tsuɔ nii jogbaŋŋ):Akɛ valve stem lɛ jeɔ ŋmei diski lɛ kɛ sealing surface teŋgbɛ lɛ fɛɛ he, ni ehaa enyɛɔ etsuɔ nii ni ekɛ ehe kpaaa gbee. Bei pii lɛ, ejieɔ dade loo nɔ ko ni akɛfee nɔ ko ni akɛfiɔ he lɛ kpo. Ehi jogbaŋŋ kɛha dɔlɛ ni nɔ kwɔ, nɔnyɛɛ ni nɔ kwɔ, nibii ni fiteɔ nii, loo nibii bibii ni yɔɔ mli.
Valve ni yɔɔ srɔto etɛ:Kɛ akɛ eccentricity enyɔ kɛ beveled conical sealing pair fata he lɛ, enine shɛɔ ŋmɔlɔ ni bɛ kɛ ŋmɔlɔ ni hoɔ, kɛ hulutsoo ni nɔ kwɔ kɛ nɔnyɛɛ ni nɔ kwɔ ni teɔ shi ewoɔ nɔ. Ehi jogbaŋŋ kɛha nitsumɔ shihilɛi ni mli wa (nɔkwɛmɔnɔ, lasu, mu/gaas, adafitswaa ni mli edɔ waa).
2. Drive mode halamɔ
Gbɛtsɔɔmɔ wolo:kɛha diamita bibii (DN≤200), shihilɛi ni mli wa waa, loo shihilɛi ni tsuuu nii shii abɔ lɛ.
Worm giya draiva:Ehi kɛha nitsumɔi ni yɔɔ teŋgbɛ kɛyashi agbo ni biɔ nitsumɔ ni mɔdɛŋbɔɔ bɛ mli loo shwiemɔ he mlai.
Kɔɔyɔɔ/Elektrik:Remote kudɔmɔ, otomashin gbɛjianɔtoi, loo oyaiyeli ni agbeɔ (tamɔ, la he ŋmɛlɛtswaa gbɛjianɔtoi, oyaiyeli ni agbeɔ).
3. Nibii ni akɛfiɔ naa kɛ nibii ni akɛtsuɔ nii
Nɔ ni yɔɔ mlɛo (rɔba, PTFE, kɛ ekrokomɛi): nɔ ni hi jogbaŋŋ, shi hulutsoo kɛ nɔnyɛɛ ni tsiɔ naa lɛ faaa (bei pii lɛ ≤120°C, PN≤1.6MPa). Ehi kɛha nu, kɔɔyɔɔ kɛ ŋmeii ni bɛ hewalɛ.
Dade ni akɛwoɔ tsɔne mli (dade ni bɛ ŋmɔlɔ, cemented carbide): Enyɛɔ eshiɔ hulutsoo be ni mli wa (ni shɛɔ 600°C), tsɔne ni tsiɔ nii waa, kɛ tsɔne ni akɛwoɔ tsɔne mli lɛ mli nibii ni fiteɔ kɛ tsɔnei ni akɛwoɔ tsɔne mli lɛ ahe nitsumɔ lɛ baa shi fioo fe tsɔnei ni akɛwoɔ tsɔne mli ni yɔɔ blɛoo lɛ. Ehi kɛha adafitswaa ni mli edɔ waa yɛ dadefeemɔ, tsɔnei ni akɛtswaa la, kɛ mu tsofai amli.
Gbɔmɔtso lɛ he nibii: Dade ni akɛwo mli, carbon dade, dade ni sɛɛ efooo, dade ni akɛfee, loo plastic/rɔba ni akɛwoɔ mli lɛ damɔ bɔ ni nɔ ni akɛwoɔ mli lɛ fiteɔ lɛ nɔ.
4. Nɔnyɛɛ kɛ dɔlɛ mli:
Akɛ ŋmeii ni yɔɔ blɛoo ni akɛwoɔ mli lɛ tsuɔ nii kɛhaa PN10~PN16, ni hulutsoo be lɛ ≤120°C. Nibii ni akɛwoɔ dade mli ni yɔɔ ŋwɛigbɛ ni yɔɔ ŋwɛigbɛ lɛ ateŋ etɛ baanyɛ ashɛ PN100 nɔ, ni hulutsoo be lɛ shɛɔ ≥600°C.
5. Trafik Sui
Kɛji akɛ ehe miihia ni ato nu ni hoɔ lɛ he gbɛjianɔ lɛ, halamɔ ŋmei valve ni nu ni hoɔ yɛ linear loo oha mlijaa 100 lɛ yeɔ egbɔ (tamɔ, V-shaped disc).
6. He ni akɛwoɔ mli kɛ gbɛtsɔɔmɔ ni hoɔ:Butterfly valve lɛ yɛ tsɔne ko ni yɔɔ mlɛo, ni no haa ehiɔ kɛha paipii ni he ko faaa. Yɛ gbɛ ni waaa nɔ lɛ, naatsii ko bɛ gbɛ ni tsɔɔ bɔ ni nu lɛ hoɔ ehaa lɛ nɔ, shi kɛha ŋmeii etɛ ni yɔɔ ŋwɛigbɛ lɛ, esa akɛ atsɔɔ gbɛ ni nu lɛ hoɔ yɛ nɔ.
II. Bei ni Akɛtsuɔ Nii
1. Nu He Buamɔ kɛ Nu He Nitsumɔ kɛ Nu He Gbɛjianɔtoi: Maŋtiase mli nu ni akɛhaa, la he paipii, kɛ muji ni ajieɔ kɛjɛɔ mli: bei pii lɛ, akɛ centerline butterfly valves ni yɔɔ blɛoo ni akɛfiɔ he lɛ tsuɔ nii, ni amɛjara waaa ni amɛyɛ nɔ ni akɛfiɔ he ni anyɛɔ akɛ he fɔ̃ɔ nɔ. Kɛha pɔmp kpojiemɔi kɛ bɔ ni hoɔ lɛ he gbɛjianɔtoo: halamɔ ŋmei gear loo srawa hewalɛ kudɔɔ akpɔlɔ valves.
2. Petrochemical kɛ adebɔɔ mli la paipii: Ahala dade ni akɛfee ŋmɔtɔ ni yɔɔ ŋwɛigbɛ ni yɔɔ ŋwɛigbɛ ni yɔɔ ŋwɛigbɛ lɛ etɛ koni ekɛtsi ŋwɛibɔfoi ni tsii waa lɛ anaa ni ekɛtsiɔ nu ni hoɔ lɛ naa. Nibii ni fiteɔ nii (tamɔ, acids/alkalis): Akɛ ŋmeii ni akɛ fluorine wo mli loo ŋmeii ni nyɛɔ efiteɔ nii lɛ tsuɔ nii.
3. Kɛha hewalɛ nitsumɔhei, nu gbɛjianɔtoi ni hoɔ, kɛ lasu mli la ni ajieɔ kɛjɛɔ mli lɛ: tsɔnei ni akɛ rɔbɔt ebɔ he ni yɔɔ teŋgbɛ loo enyɔ. Kɛha steam paipii (tamɔ, yelikɛbuamɔ nibii ni akɛtsuɔ nii yɛ tsɔnei ni akɛwoɔ la mli lɛ amli): eccentric dade-sealed butterfly valves etɛ.
4. HVAC (Heating, Ventilation, and Air Conditioning) nu ni mli ejɔ kɛ nu ni mli edɔ lɛ he gbɛjianɔtoi: ŋmeii ni yɔɔ blɛoo ni akɛkwɛɔ nu ni hoɔ lɛ nɔ loo afoɔ mli.
5. Kɛha ŋshɔ hiɛ tsɔne he nitsumɔ kɛ ŋshɔ mli nu paipii: dade ni akɛfee ŋmɔtɔ ni nyɛɔ efiteɔ loo ŋmɔtɔ ni akɛ rɔba fee lɛ.
6. Niyenii kɛ tsofafeemɔ mli ŋmeii valvɛi (dade ni afee lɛ ŋmɔlɔŋmɔlɔ, nibii ni akɛwoɔ mli oya) kɛ sterile taomɔ nii lɛ kpãa gbee.
7. Dust kɛ particulate media yɛ nitsumɔ shihilɛi krɛdɛɛi amli: Akɛ butterfly valves ni mli wa ni nyɛɔ efiteɔ lɛ he ŋaawoo haa (tamɔ, kɛha mine powder ni akɛyaa).
Vacuum gbɛjianɔtoo: Vacuum krɛdɛɛ koŋmei valveekwɛɔ koni sealing lɛ atsu nii jogbaŋŋ.

TWSjeee hefatalɔ ni akɛ he fɔ̃ɔ enɔ kɛha nɔ ni hi jogbaŋŋ pɛŋmeii valvɛishi ekɛ ŋaa gbɛ nɔ nilee babaoo kɛ tsabaai ni ana he odaseyeli hu fɔ̃ɔ ehe nɔ yɛshinaa lɛ naa valvɛi, kwɛmɔ valvɛi lɛ, kɛkɔɔyɔɔ ni ajieɔ lɛ mli valvɛi. Bɔ fɛɛ bɔ ni otaomɔi ni kɔɔ nu he lɛ ji lɛ, wɔkɛ ŋaalɔi, valve ni haa mɔ tsui nyɔɔ emli lɛ yelikɛbuamɔ haa. Kɛji ootao nitsumɔi loo ŋaa saji lɛ, ofainɛ feemɔ oya ni otswa wɔ be fɛɛ be.
