• Kuuma ndi kuuma pamwamba

Momwe mungayang'anire Block, gate, globe, butterfly, cheke, ndi ma valve a mpira?
• Kuyika ndi zojambulajambula ziyenera kuyang'aniridwa
• Kuyeza kwa ma valve kumayenera kuchitidwa ngati chipolopolo, mpando wakumbuyo, kutseka kwapansi ndi kuthamanga kwambiri.
• Kuyesa kutulutsa mpweya wothawathawa
• Kuyesa kwa Cryogenic ndi kutentha kochepa
• Kuyang'ana kowoneka ndi kukula molingana ndi zojambula za data

Momwe mungayang'anire ma valve ochepetsa kuthamanga?
• Kuyang'ana zokopa
• Kuyesedwa kwa PSV, thupi, ndi nozzle
• Mayeso ogwira ntchito a PSV- set pressure test, set tightness test, back pressure test.
• Kuyang'ana kowoneka ndi mawonekedwe

Momwe mungayang'anire pamtsinje wa valve control?
• Chida choyenera chothandizira chiyenera kuikidwa
• Onani ngati zoikamo zokakamiza zili zoyenera
• Yang'anani kutayikira kulikonse
• Gasi, makhungu, ma valve otsekedwa, kapena kutsekeka kwa mapaipi sayenera kukhalapo
• Zisindikizo zomwe zimateteza kasupe siziyenera kuthyoledwa
• Onani ngati zipangizo zothandizira zikutha kapena ayi
• Kuyezetsa ultrasonic kuyenera kuchitika

Momwe mungatetezere chitetezo pakuwunika ma valve owongolera?
• Tisanachotse valavu pamzere gawo la mzere wokhala ndi valavu liyenera kutsekedwa kuchokera kuzinthu zonse zamadzimadzi zovulaza, mpweya, kapena nthunzi.Chifukwa chake gawo ili la mzere liyenera kukhala lodetsa nkhawa ndikuchotsa mafuta onse, poizoni, kapena mpweya woyaka.Chida choyendera chiyenera kufufuzidwa chisanachitike.

Momwe mungayang'anire valve yolakwika?
• Yang'anani chipika choyendera chomera ndikuwunikanso zida zowunikira kuti zidziwitso za kulephera kwa valve
• Zida zomwe zidakonzedwa kwakanthawi ziyenera kuchotsedwa monga zomangira, mapulagi, ndi zina.
• Yang'anani valavu kuti muwone kuwonongeka kwa makina kapena dzimbiri
• Yang'anani mabawuti ndi mtedza ngati zachita dzimbiri
• Yang'anani ngati malo omangirira ali ndi makulidwe oyenera komanso yang'anani ubwino wa thupi la valve
• Yang'anani ngati chipata kapena chimbale chatetezedwa bwino pa tsinde
• Maupangiri omwe ali pachipata ndi thupi lawo ayenera kuyang'aniridwa ngati zachita dzimbiri
• Tiyenera kuyang'ana wotsatira wa gland, ngati wotsatira asinthidwa mpaka pansi ndiye kulongedza kowonjezera kudzafunika
• Yang'anani ngati valavu ingagwiritsidwe ntchito mosavuta ngati sichoncho ndiye kuti paketiyo iyenera kusinthidwa

Momwe mungayang'anire valavu yowongolera yomangidwanso kapena yokonzedwa?
• Ngati mbali za valve zasinthidwa ndiye kuti muwone ngati zida zolondola zayikidwa
• Tiyeneranso kufufuza ngati zida zochepetsera za valve ndizoyenera mtundu wa utumiki
• Tiyenera kuyesa hydro-test kuti tidziwe ngati valavu yokonzedwayo ndiyoyenera kugwira ntchito
• Kuyezetsa kwapampando kuyenera kuchitidwa pa valve yomwe ikufunika kutsekedwa mwamphamvu ngati chowongolera chakonzedwa kapena kusinthidwa
• Ngati gasket ndi kulongedza zakonzedwanso ndiyeso zolimba ziyenera kuchitidwa
