Valavu Yothandizira Mpweya Wopopera Chitsulo Chopopera Mpweya Wo ...

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.

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.
Valavu yotulutsa mpweya wothamanga kwambiri imatha kutulutsa mpweya womwe umasonkhana pamalo okwera kwambiri mu dongosololi panthawi yomwe dongosololi lili pansi pa kupanikizika kuti tipewe zochitika zotsatirazi zomwe zingawononge dongosololi: kutseka mpweya kapena kutsekeka 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 womwe uli mu payipi ukatha, madzi amalowa mu valavu yolowetsa mpweya ndi yotulutsa mpweya yotsika, ndipo choyandamacho chimakwezedwa ndi choyandama kuti chitseke madoko olowetsa mpweya ndi otulutsa 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 yophatikizana ya mpweya pamene kupanikizika mu dongosolo kuli kotsika komanso kupsinjika kwa mlengalenga (kupanga kupsinjika 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.
