Mfundo yogwira ntchito ya dziko lapansivalavu:

Madzi amabayidwa kuchokera pansi pa chitoliro ndi kumasulidwa kukamwa kwa chitoliro, poganiza kuti pali mzere woperekera madzi wokhala ndi kapu. Chophimba cha chitoliro chotuluka chimagwira ntchito ngati njira yotseka ya valve yoyimitsa. Madzi adzatulutsidwa panja ngati kapu ya chitoliro imakwezedwa pamanja. Madzi amasiya kusambira ngati kapu ya chubu itaphimbidwa ndi dzanja lanu, zomwe zimafanana ndi ntchito ya valve yoyimitsa.

Makhalidwe a valve ya globe:

Akayika, otsika mkati ndi otsika, oyenda molunjika, kukana kukangana kwamadzi kwakukulu, kupanga ndi kukonza bwino, kapangidwe kosavuta, kulondola kwambiri; amagwiritsidwa ntchito makamaka m'madzi otentha ndi ozizira komanso mapaipi othamanga kwambiri; sizikugwira ntchito Zosungunulira zokhala ndi tinthu tating'onoting'ono komanso kukhuthala kwakukulu.

Mfundo yogwiritsira ntchito valve:

Malo ozungulira polowera ndi kutuluka ayenera kuwoneka kwathunthu pamene valavu ya mpira yazungulira madigiri 90. Pa nthawiyo, valavu imatsekedwa kuti aletse zosungunulira kusambira. Payenera kukhala mipata ya mpira pakhomo ndi podutsa pamene valavu ya mpira imazungulira madigiri 90, ndipo iyenera kutsegulidwa ndi kusambira kuti pasakhale kukana kuyenda.
Makhalidwe a ma valve a mpira:

Thevalavu ya mpirandi yosavuta kugwiritsa ntchito, yachangu, komanso yopulumutsa. Vavu ya mpira imatha kugwiritsidwa ntchito ndi madzi omwe sali oyera kwambiri (okhala ndi tinthu tating'onoting'ono) mwa kungotembenuza chogwirira cha 90 °. Izi zili choncho chifukwa madziwa amakhudzidwa ndi chigawo chapakati cha valve pamene atsegulidwa ndi kutsekedwa. ndiye kuyenda kwa kudula.

Mfundo yogwira ntchito ya valve gate:

Mtundu wodziwika bwino wa valve ndi valavu yachipata, yomwe nthawi zina imadziwika kuti valve valve. Mfundo yake yotseka ndi yotseka yogwirira ntchito ndikuti malo osindikizira a mbale ya pachipata ndi mpando wa valve, omwe amalumikizana kuti atseke kutuluka kwa madzi apakati ndi kupititsa patsogolo ntchito yosindikiza pogwiritsa ntchito kasupe kapena chitsanzo cha thupi la mbale ya chipata, ndizovuta kwambiri. yosalala komanso yosasinthasintha. zotsatira zenizeni. Ntchito yayikulu ya valve pachipata ndikuyimitsa njira yamadzimadzi kudzera mupaipi.

Zofunika za valve gate:

Ntchito yosindikiza ndiyopambana kuposa ya valavu yapadziko lonse lapansi, kukana kwamadzimadzi kumakhala kochepa, kutsegula ndi kutseka kumafunikira ntchito zambiri, malo osindikizira sawonongeka pang'ono ndi zosungunulira akamatseguka, ndipo kusindikiza sikumayendetsedwa ndi njira yoyendetsera zinthu. Nthawi yotsegula ndi yotsekera ndi yayitali, kukula kwake ndi kwakukulu, ndipo malo enieni amafunika. Potsegula ndi kutseka, malo osindikizira amakokoloka mosavuta ndikudulidwa. Mawiri awiri osindikizawa ali ndi zovuta pakukonza, kukonza, ndi kupanga.

Chidule cha kusiyana pakati pa ma valve a globe,ma valve a mpirandi ma valve a gate:

Ngakhale ma valve a globe amatha kugwiritsidwa ntchito poyendetsa kayendedwe ka madzi komanso kusintha kwamadzimadzi komanso kudula, mavavu a mpira ndi ma valve a pachipata nthawi zambiri amagwiritsidwa ntchito posinthira madzimadzi ndikudula komanso kawirikawiri pakuwongolera kayendedwe kake. Ndi bwino kugwiritsa ntchito valve yoyimitsa kumbuyo kwa mita pamene mukufunikira kusintha kayendedwe kake. Ma valve a zipata amagwiritsidwa ntchito posintha zowongolera komanso zodula chifukwa ndizothandiza kwambiri pazachuma. Kapena, pamapaipi akuluakulu, otsika kwambiri amafuta, nthunzi, ndi madzi, gwiritsani ntchito ma valve a zipata. Kulimba kumafuna kugwiritsa ntchito ma valve a mpira. Ma valve a mpira ndi apamwamba kuposa ma valve a pachipata potengera chitetezo komanso moyo wautali, ndipo amatha kugwiritsidwa ntchito m'malo okhala ndi njira zotsikirapo. Amakhalanso oyenera kutsegula ndi kutseka mwamsanga.
