Mfundo yoyendetsera ntchito ya valve yoyandama ndi kapangidwe kake

Kufotokozera mwachidule zavalavu yoyandama:
Vavu imakhala ndi mkono wopindika ndi choyandama ndipo imatha kugwiritsidwa ntchito kuwongolera madzi munsanja yozizira kapena posungira dongosolo.Kukonzekera kosavuta, kusinthasintha ndi kukhazikika, kulondola kwa mlingo wamadzimadzi, mzere wa madzi sungakhudzidwe ndi kupanikizika, kutsegula ndi kutseka kwapafupi, palibe madzi amadzimadzi.
Mpira ulibe nsonga yothandizira, ndipo umathandizidwa ndi ma valve a 2 othamanga kwambiri.Zili m'malo osinthasintha ndipo ndizoyenera kutulutsa, kutumiza ndikusintha komwe kumayenda kwa zinthu zomwe zili mupaipi.Zofunikira za valve yothamanga ndi dongosolo lapamwamba lachipata chosindikizira chosindikizira, mpando wodalirika wotsekedwa wotsekedwa, chitetezo cha moto cha electrostatic induction effect, mpumulo wodziwikiratu, zida zotsekera ndi zina mwamapangidwe.
Mfundo ya valve yoyandama:
Mfundo ya valve yoyandama sizovuta.Kwenikweni, ndi valavu wamba yotseka.Pali lever pamwamba.Mapeto amodzi a lever amakhazikika pa gawo lina la valavu, ndiye pa mtunda uwu ndi kumalo ena kuzungulira kuzungulira, minofu yomwe imagwira ntchito ya valve imathyoledwa, ndipo mpira woyandama (mpira wopanda kanthu) umayikidwa kumapeto kwa mchira. wa lever.
Zoyandamazo zakhala zikuyandama m’nyanja.Mtsinje ukakwera, mtsinjewo umayandamanso.Kukwera kwa choyandama kumakankhira crankshaft kuti nayonso ikwere.Crankshaft imalumikizidwa ndi valavu kumapeto kwina.Ikakwezedwa pamalo enaake, crankshaft imachirikiza pulasitiki ya pisitoni ndodo ndikuzimitsa madzi.Mzere wamadzi ukatsika, choyandamacho chimatsikanso ndipo crankshaft imakankhira pisitoni ndodo zotseguka.
Valavu yoyandama imayendetsa kuchuluka kwa madzi molingana ndi mulingo wamadzimadzi womwe umagwiritsidwa ntchito.Evaporator yonse yamadzimadzi imanena kuti mulingo wamadzimadzi umasungidwa pautali wina wake, womwe nthawi zambiri umakhala woyenera valavu yokulira ya chowongolera mpweya woyandama.Mfundo yoyendetsera ntchito ya valve yoyandama ndikuwongolera kutsegula kapena kutseka kwa valve pogwiritsa ntchito kuchepetsa ndi kukwera kwa choyandama mu chipinda choyandama chomwe chimavulazidwa ndi mlingo wamadzimadzi.Chipinda choyandama chili mbali imodzi ya evaporator yodzaza madzi, ndipo mipope yofananira kumanzere ndi kumanja imalumikizidwa ndi evaporator, kotero kuti mulingo wamadzimadziwo ndi wofanana kutalika kwake.Pamene mlingo wamadzimadzi mu evaporator umatsitsidwa, mlingo wamadzimadzi mu chipinda choyandama umatsitsidwanso, kotero mpira woyandama umatsitsidwa, kutsegula kwa valve kumakwezedwa molingana ndi lever, ndipo kuchuluka kwa madzi kumakwezedwa.Chosiyana ndi chowonanso.
Kapangidwe ka valve yoyandama:
Zofunika za valve yoyandama:
1. Tsegulani kukakamiza kugwira ntchito mpaka zero.
2: Mpira wawung'ono woyandama umayang'anira kutsegulira ndi kutseka kwa valve yayikulu, ndipo kukhazikika kotseka ndikwabwino.
3. Kutha kugwira ntchito kwakukulu kwa kayendedwe kazinthu.
4. Kupanikizika kwakukulu.
Kufotokozera kwachitsanzo cha valavu yoyandama: G11F m'mimba mwake mwadzina la chitoliro: DN15 mpaka DN300.
Kalasi ya mapaundi: 0.6MPa-1.0MPa Kupanikizika kochepa kovomerezeka kolowera: 0MPa.
Zinthu zomwe zingagwiritsidwe ntchito: madzi apakhomo, valavu yoyeretsera madzi otsekemera Zida: 304 mbale yachitsulo chosapanga dzimbiri.
Mkati dongosolo Zopangira: 201, 301, 304 kutentha ntchito: madzi ozizira mtundu ≤ 65 ℃ madzi owiritsa mtundu ≤ 100 ℃.
