Valavu yotulutsa mpweya yophatikizika ndi chipangizo chofunikira kwambiri chopumira mpweya m'mapaipi, chomwe chapangidwa mwapadera kuti chithetse mavuto monga kusonkhanitsa mpweya ndi kupopera mphamvu m'mapaipi. Ili ndi ntchito zotulutsa mpweya zokha komanso zokoka mpweya ndipo imagwiritsidwa ntchito kwambiri pazochitika zosiyanasiyana zoyendera madzi monga madzi, zimbudzi, ndi mankhwala.

Makhalidwe ake apakati amayang'ana kwambiri pakugwira ntchito bwino komanso kudalirika: Choyamba, ili ndi mpweya wolowera mbali zonse ziwiri. Siimangotulutsa mpweya wambiri mwachangu pamene payipiyo yadzazidwa ndi madzi kuti mpweya usatsekeke, komanso imangokoka mpweya wokha pamene payipiyo yachotsedwa kapena kupanikizika kumatsika kwambiri kuti payipiyo isawonongeke ndi kuwonongeka chifukwa cha kupanikizika koipa. Chachiwiri, imatsimikizira kuti mpweya utuluka bwino. Kapangidwe kake kamene kamapangidwa bwino komanso kolimba ka valavu kamatha kutulutsa mpweya wochepa mu payipiyo, zomwe zimatsimikizira kuti madzi akuyenda bwino.

Chachitatu, sichimadwala dzimbiri komanso chimakhala cholimba. Thupi la valavu limapangidwa makamaka ndi zinthu zapamwamba monga chitsulo chosungunuka ndi chitsulo chosapanga dzimbiri, ndipo zida zotsekera zimapangidwa ndi rabara kapena PTFE yosatha, yomwe ndi yoyenera kugwiritsa ntchito zinthu zosiyanasiyana komanso mikhalidwe yogwirira ntchito ndipo imakhala ndi moyo wautali. Chachinayi, ndi yosavuta kuyiyika, imathandizira kuyiyika koyima pamalo okwera, kumapeto kwa mapaipi kapena malo omwe ali ndi mphamvu yoipa, komanso imakhala ndi ndalama zochepa zosamalira.

Njira zogwiritsira ntchito madzi ndi zambiri: m'ma network a madzi a m'matauni, amagwiritsidwa ntchito m'mapaipi otulutsira madzi m'malo otulutsira madzi, m'malo okwera a mapaipi akuluakulu komanso m'mizere yotumizira madzi yakutali kuti apewe kusagwirizana kwa madzi komwe kumachitika chifukwa cha kukana mpweya. Mu dongosolo la madzi ndi ngalande m'nyumba zazitali, imayikidwa pamalo otulutsira madzi padenga komanso pamwamba pa chokwezera madzi kuti athetse mavuto otulutsa utsi ndi kupanikizika kwa madzi okwera. M'mafakitale, imagwiritsidwa ntchito m'mapaipi oyendera madzi apakatikati m'mafakitale opanga mankhwala, magetsi ndi zitsulo, makamaka zofunikira pa mpweya wabwino m'mapaipi apakatikati otentha kwambiri, opanikizika kwambiri kapena owononga.

Mu malo oyeretsera zinyalala, imagwiritsidwa ntchito potulutsira mapampu okweza zinyalala, mapaipi olowetsa mpweya ndi mapaipi obweza kuti zitsimikizire kuti njira yoyeretsera zinyalala ndi yokhazikika. Kuphatikiza apo, imagwiritsidwa ntchito kwambiri mu ulimi wothirira, makina oyendera madzi oziziritsa mpweya, ndi zina zotero, zomwe zimapereka chitsimikizo cha magwiridwe antchito otetezeka komanso ogwira mtima a mapaipi osiyanasiyana. 

Jinbin Valve yakhala ikugwiritsidwa ntchito popanga mavavu kwa zaka 20, kuphatikizapo mavavu osiyanasiyana a chipata,valavu yapadziko lonse, valavu yoyezera, valavu yotulutsa mpweya, valavu ya mpira, valavu ya gulugufe, ndi zina zotero. Tadzipereka kupereka mayankho abwino kwambiri a valavu kwa makasitomala apadziko lonse lapansi. Ngati muli ndi mafunso okhudzana ndi izi, chonde siyani uthenga pansipa ndipo mudzalandira yankho mkati mwa maola 24!
