A valavu ya phazindi achekeni valavuzomwe zimangolola kuyenda kumbali imodzi. Valavu ya phazi imagwiritsidwa ntchito pamene pampu ikufunika, monga pamene madzi akuyenera kuchotsedwa pachitsime chapansi. Valve ya phazi imasunga mpope, kulola kuti madzi alowemo koma osawalola kuti abwerere, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'madziwe, maiwe ndi zitsime.

Momwe valavu ya phazi imagwirira ntchito
Monga valve yomwe imalola kuyenda kwa njira imodzi yokha, phazi la phazi limatsegula njira imodzi ndikutseka pamene kutuluka kuli kosiyana. Izi zikutanthauza kuti muzogwiritsira ntchito monga zitsime, madzi amatha kuchotsedwa pachitsime. Madzi aliwonse omwe atsala m'chitoliro saloledwa kubwereranso kudzera mu valve kupita kuchitsime. Tiyeni tione mwatsatanetsatane ndondomekoyi.

M'zitsime zamadzi osaya pansi, kugwiritsa ntchito ma valve apapazi kumaphatikizapo izi:

Choyamba, ganizirani malo a valve ya phazi. Imayikidwa kumapeto kwa chitoliro (kumapeto kwa chitsime chomwe madzi amachotsedwa). Ili pafupi ndi pansi pa chitsime.
Pamene mpope ikuyenda, kuyamwa kumapangidwa, kutulutsa madzi kudzera mu chitoliro. Chifukwa cha kupanikizika kwa madzi omwe amalowa, valavu yapansi imatsegula pamene madzi akuyenda mmwamba.
Pompo ikazimitsidwa, kuthamanga kwapamwamba kumayima. Izi zikachitika, mphamvu yokoka imagwira ntchito pamadzi omwe atsala m'chitoliro, kuyesera kuwatsitsimutsanso m'chitsime. Komabe, valavu ya phazi imalepheretsa izi kuti zisachitike.
Kulemera kwa madzi mu chitoliro kumakankhira valavu yapansi pansi. Chifukwa valavu yapansi ndi njira imodzi, simatsegula pansi. M'malo mwake, kuthamanga kwa madzi kumatseka valavu mwamphamvu, kulepheretsa kubwereranso m'chitsime ndi kuchoka pampope kubwerera ku sump.
Gulani PVC Phazi Mavavu

Nchifukwa chiyani mukufunikira valve ya phazi?
Mavavu amapazi ndi opindulitsa chifukwa amalepheretsa kuwonongeka kwa mpope chifukwa chakuchita bwino komanso kusiya kuwononga mphamvu.

Ma valve awa ndi gawo lofunikira pa makina aliwonse opopera. Chitsanzo pamwambapa chikufotokozera momwe valavu ya phazi imagwirira ntchito pamlingo wochepa kwambiri. Ganizirani zotsatira za kusagwiritsa ntchitovalavu ya phazimuzochitika zazikulu, zapamwamba.

Pankhani ya kupopera madzi kuchokera ku sump pansi kupita ku thanki pamwamba pa nyumba, m'pofunika kugwiritsa ntchito pampu yamphamvu yamagetsi. Mofanana ndi zitsanzo, mapampuwa amagwira ntchito popanga kuyamwa komwe kumakakamiza madzi kupyola mu mipope kupita ku tanki yomwe mukufuna.

Pamene mpope ikuyenda, pali mzere wamadzi nthawi zonse mu chitoliro chifukwa cha kuyamwa kwaiye. Koma pamene mpope wazimitsidwa, kuyamwa kwapita ndipo mphamvu yokoka imakhudza chigawo cha madzi. Ngati valavu ya phazi silinakhazikitsidwe, madzi amayenda pansi pa chitoliro ndikubwerera ku chiyambi chake. Mipope idzakhala yopanda madzi, koma idzadzazidwa ndi mpweya.

Kenako mpopeyo ikayatsidwanso, mpweya wa m’paipiwo umatsekereza madzi, ndipo ngakhale mpopeyo utayaka, madziwo sangayende papaipiyo. Izi zikachitika, zimatha kuyambitsa idling ndipo, ngati siziyankhidwa mwachangu, zitha kuwononga mpope.

Valavu yapansi imathetsa bwino vutoli. Pompo ikazimitsidwa, salola kuti madzi abwerere mmbuyo. Pampuyo imakhala yokonzeka kugwiritsidwa ntchito motsatira.

Cholinga cha valve ya phazi
Valve ya phazi ndi valavu yoyendera yomwe imagwiritsidwa ntchito ndi pampu. Amagwiritsidwa ntchito m'malo osiyanasiyana kunyumba komanso m'mafakitale ena. Mavavu amapazi amatha kugwiritsidwa ntchito ndi mapampu omwe amapopa zakumwa (zotchedwa hydraulic pumps) (monga madzi) kapena ntchito zamakampani (monga mpweya) (otchedwa mapampu a pneumatic).

Kunyumba, ma valve amapazi amagwiritsidwa ntchito m'mayiwe, maiwe, zitsime, ndi kwina kulikonse komwe kuli ndi mpope. M'mafakitale, ma valveswa amagwiritsidwa ntchito m'mapampu amadzimadzi, mapampu a mpweya omwe amagwiritsidwa ntchito m'mitsinje ndi nyanja, mizere ya air brake yamagalimoto amalonda, ndi zina zomwe mapampu amagwiritsidwa ntchito. Amagwiranso ntchito m'mafakitale monga momwe amachitira padziwe lakumbuyo.

Valavu ya phazi idapangidwa kuti pampu ikhale yokhazikika, kuti madzi azitha kulowa mkati, koma osatuluka. Pali zosefera zomwe zimaphimba kutseguka kwa valve ndipo zimatha kutseka pakapita nthawi - makamaka ngati zimagwiritsidwa ntchito pochotsa madzi pachitsime kapena dziwe. Choncho, ndikofunika kuyeretsa valve nthawi zonse kuti ikhale yogwira ntchito bwino.

Sankhani valavu ya phazi lakumanja
valavu ya phazi lamkuwa

Vavu ya phazi imafunika nthawi zambiri. Nthawi iliyonse pali ntchito yomwe imafuna unidirectional fluid flow, valve phazi ikufunika. Valve yamtundu wabwino imathandiza kupulumutsa mphamvu ndikuteteza mpope kuti zisawonongeke, kukulitsa moyo wake wonse. Kumbukirani kuti ndikofunikira kugwiritsa ntchito valavu ya phazi yabwino kwambiri, chifukwa imatha kukhala yovuta kuipeza ikangoyikidwa.
