Kufotokozera:

Valavu yotulutsa mpweya wothamanga kwambiri imaphatikizidwa ndi magawo awiri a air-pressure diaphragm air valve ndi low pressure inlet and exhaust valve, Imakhala ndi ntchito zotulutsa komanso zotulutsa.
Valavu yotulutsa mpweya wothamanga kwambiri wa diaphragm imangotulutsa mpweya wocheperako womwe umawunjikana mupaipi pomwe payipi ikapanikizika.
The otsika-anzanu kudya ndi utsi valavu sangathe kutulutsa mpweya mu chitoliro pamene chopanda kanthu chitoliro wodzazidwa ndi madzi, komanso pamene chitoliro atakhuthula kapena kupanikizika koipa kumachitika, monga pansi pa madzi ndime kulekana chikhalidwe, izo basi kutsegula ndi kulowa chitoliro kuthetsa mavuto zoipa.

Imodzi mwa ntchito zazikulu za valve yotulutsa mpweya ndikutulutsa mpweya wotsekeka kuchokera mudongosolo. Madzi akalowa m’mipope, mpweya ukhoza kutsekeredwa m’malo okwera, monga mapindikidwe, malo okwera, ndi nsonga zamapiri. Pamene madzi amadzimadzi akuyenda m'mapaipi, mpweya ukhoza kuwunjikana ndikupanga matumba a mpweya, zomwe zingayambitse kuchepa kwachangu ndi kuwonjezereka kwamphamvu.

Ma valve otulutsa mpweya, monga ena a TWS Valvemphira wokhala pansi agulugufe mavavu, zimathandizanso kwambiri kuti mapaipi ndi makina onyamula madzi aziyenda bwino komanso kuti asagwire bwino ntchito. Kuthekera kwawo kumasula mpweya wotsekeka ndikuletsa mikhalidwe ya vacuum kumapangitsa kuti dongosololi liziyenda bwino, kupewa kusokoneza ndi kuwonongeka. Pomvetsetsa kufunikira kwa ma valve otulutsa mpweya komanso kutenga njira zoyenera zoyikira ndi kukonza, oyendetsa makina amatha kuonetsetsa kuti nthawi yayitali komanso kudalirika kwa mapaipi awo ndi machitidwe awo.

Zofunikira pakuchita:

Valve yotsika yotulutsa mpweya (yoyandama + mtundu woyandama) doko lalikulu lotulutsa mpweya limatsimikizira kuti mpweya umalowa ndikutuluka pamlingo wothamanga kwambiri pamtunda wothamanga kwambiri, ngakhale mpweya wothamanga kwambiri wosakanikirana ndi nkhungu yamadzi, Sizidzatseka doko lotulutsa pasadakhale.
Nthawi iliyonse, malinga ngati kupanikizika kwa mkati mwa dongosolo kumakhala kotsika kusiyana ndi kupanikizika kwa mlengalenga, mwachitsanzo, pamene kupatukana kwa madzi kukuchitika, valavu ya mpweya idzatsegulidwa nthawi yomweyo kuti mpweya ulowe mu dongosolo kuti ateteze kubadwa kwa vacuum mu dongosolo. Panthawi imodzimodziyo, kutengeka kwa mpweya panthawi yake pamene dongosolo likukhuthula kungathe kufulumizitsa kuthamanga. Pamwamba pa valavu yotulutsa mpweya imakhala ndi mbale yotsutsa-irritating kuti ikhale yosalala, yomwe ingalepheretse kusinthasintha kwa kuthamanga kapena zochitika zina zowononga.
The high-pressure trace exhaust valve imatha kutulutsa mpweya womwe umasonkhanitsidwa pamalo apamwamba mu dongosolo panthawi yomwe dongosolo limakhala lopanikizika kuti lipewe zochitika zotsatirazi zomwe zingawononge dongosolo: kutsekedwa kwa mpweya kapena kutsekedwa kwa mpweya.
Kuchulukitsa kutayika kwa mutu wa dongosolo kumachepetsa kuthamanga kwa magazi ndipo ngakhale pazovuta kwambiri kungayambitse kusokoneza kwathunthu kwa madzimadzi. Limbikitsani kuwonongeka kwa cavitation, fulumizitsa dzimbiri zazitsulo, onjezerani kusinthasintha kwa makina, onjezerani zolakwika za zida za metering, ndi kuphulika kwa mpweya. Limbikitsani kagwiritsidwe ntchito ka madzi bwino pamapaipi.

Mfundo yogwirira ntchito:

Njira yogwirira ntchito yophatikiza mpweya valavu pamene chitoliro chopanda kanthu chili ndi madzi:
1. Kukhetsa mpweya mu chitoliro kuti kudzaza madzi kuyende bwino.
2. Mpweya wa payipi utatha, madzi amalowa muzitsulo zotsika kwambiri komanso zotulutsa mpweya, ndipo choyandamacho chimakwezedwa ndi buoyancy kuti asindikize madoko olowera ndi kutulutsa mpweya.
3. Mpweya womwe umatulutsidwa m'madzi panthawi yoperekera madzi udzasonkhanitsidwa pamtunda wapamwamba wa dongosolo, ndiko kuti, mu valve ya mpweya kuti ilowe m'malo mwa madzi oyambirira mu thupi la valve.
4. Ndi kudzikundikira kwa mpweya, mlingo wamadzimadzi mu valavu yotulutsa mpweya wothamanga kwambiri umatsika, ndipo mpira woyandama umatsikanso, kukoka diaphragm kuti isindikize, kutsegula doko lotulutsa mpweya, ndikutulutsa mpweya.
5. Mpweya ukatulutsidwa, madzi amalowanso mu valve yothamanga kwambiri ya micro-automatic exhaust, amayandama mpira woyandama, ndikusindikiza doko lotulutsa mpweya.
Dongosolo likayamba, masitepe 3, 4, 5 omwe ali pamwambapa apitiliza kuzungulira
Njira yogwirira ntchito ya valavu yophatikizika ya mpweya pamene kupanikizika m'dongosolo kumakhala kochepa komanso kuthamanga kwamlengalenga (kutulutsa kupanikizika koipa):
1. Mpira woyandama wocheperako komanso valavu yotulutsa mpweya udzagwa nthawi yomweyo kuti mutsegule madoko olowera ndi kutulutsa.
2. Mpweya umalowa m'dongosolo kuyambira pano kuti uthetse kupanikizika koipa ndikuteteza dongosolo.
