Valve Basic

A vvalavunchibelesyo cheendelezya mulongo wamaanzi. Mulimu wayo mupati ngwakuswaanganya naa kugonka kweendeenda kwa ringi yamupaipi, kuchincha nzila kweenda kwamupaipi, kuchincha kusinikizyigwa akweenda kwamupaipi, akukwabilila kweenda kabotu kwamupaipi azibelesyo.

一．Kwaandaanya mavalvu

Kweelana akubelesya amulimu ulakonzya kwaandaanizyigwa mu:

1. Ivalvu yakujala: kosola naa kuswaanganya nzila yamupaipi. Mbuli: vvalavu yamulyango, vvalavu ya globe, vvalavu ya bbola, vvalavu ya butterfly, vvalavu ya diaphragm, vvalavu ya plug.

2. Valve yakulanga: kukasya chintu chili mumupayipi kuti chitanjili musule.

3. Ivalavu yakumwaya: kuchincha nzila yakuzuza kwachintu, kwaabila, kwaandaanya naa kusanganya chimwi chintu. Mbuli mavalvu aakwaabila, zibelesyo zyakujata busi, antoomwe amavalvu aajisi nzila zyotatwe.

4. Kubamba vvalavu: bambulula muya akuzuza kwamukati. Mbuli vvalavu yakugwisya muya, vvalavu iilanganya, vvalavu yakugwisya muya.

5. Ivalavu yakukwabilila: ilalesya muya uuzwa aakati-akati muchibelesyo kuti utaindili aawo mpoyelede, mpawo upe lukwabililo lwamuwo mupati.

二. Zibeela zyantalisyo zyavvalavu

1. Bulamfu bwa valve (DN).

2. Kuyuma kwa valve (PN).

3. Kusinikizyigwa akupya kwa vvalavu: Eelyo kupya kwa vvalavu nokwainda kupya kwa vvalavu, nguzu zyakwe zyakubeleka zyeelede kucheya kweendelana.

4. Kusanduka kwa yuniti ya nguzu zya valve:

5. Nzila iibeleka yavvalavu:

Mavalvu aamakkampani abelesyegwa mumakkampani aamafuta, mumakkampani aamakemikalu, mumakkampani aapanga zintu zyabutale, manguzu aamagesi, manguzu aamu nyukiliya amakkampani aambi. Inzila zyakukambawukila zibikkilizya muya (muya, busi, ammonia, muya wamalasha, muya wamafuta, muya uuzwa kuzilenge, azimwi); maanzi (maanzi, ammonia yamaanzi, mafuta, ma asidi, ma alkali, azimwi). Zimwi zilakonzya kubola mbuli mfwulumende, mpawo zimwi zilakonzya kuba aanguzu zya radioactive.
