Cholinga chogwiritsa ntchito ma valve oyesera ndikuletsa kuyenda kwa cholumikizira, makamaka potumiza pampu kuti ikayike ma valve oyesera. Kuphatikiza apo, ma valve oyesera ayenera kuyikidwa pamalo otulukira compressor. Kawirikawiri, ma valve oyesera ayenera kuyikidwa mu zida, mayunitsi kapena mizere kuti apewe reflux ya media.
Ma valve oyezera kukweza olunjika nthawi zambiri amagwiritsidwa ntchito m'mimba mwake wa payipi yopingasa ya 50mm. Ma valve oyezera kukweza olunjika amatha kuyikidwa m'mizere yopingasa komanso yopingasa. Valavu yapansi nthawi zambiri imayikidwa mu chitoliro choyima cha pompu yolowera, ndipo sing'anga imatuluka kuchokera pansi kupita pamwamba.
Valavu yoyesera yozungulira imatha kupangidwa kuti igwire ntchito mwamphamvu kwambiri, PN mpaka 42MPa, ndipo DN ikhozanso kukhala yayikulu kwambiri, mpaka 2000mm. Malinga ndi zinthu zomwe zili mu chipolopolo ndi chisindikizo, ingagwiritsidwe ntchito pa chipangizo chilichonse chogwirira ntchito komanso kutentha kulikonse kogwirira ntchito. Chapakati ndi madzi, nthunzi, gasi, chowononga, mafuta, chakudya, mankhwala ndi zina zotero. Kutentha kogwirira ntchito kwa chipangizocho kuli pakati pa -196 ℃ ndi 800℃.
Ma valve oyesera ma swing nthawi zambiri amaikidwa m'mizere yopingasa, koma amathanso kuyikidwa m'mizere yoyima kapena yopendekera.
Valavu yoyesera ya gulugufe ndi yoyenera kupanikizika kochepa komanso m'mimba mwake waukulu, ndipo nthawi zoyikira zimakhala zochepa. Chifukwa kuthamanga kwa ntchito kwa valavu yoyesera gulugufe sikungakhale kwakukulu kwambiri, koma m'mimba mwake wodziwika bwino kungakhale kwakukulu kwambiri, kumatha kufika 2000mm, koma kuthamanga kwake kuli pansi pa 6.4mpa. Mavavu oyesera gulugufe amatha kupangidwa kukhala mtundu wa wafer, nthawi zambiri amaikidwa pakati pa ma flange awiri a payipi, pogwiritsa ntchito mawonekedwe a cholumikizira cholumikizira.
Ma valve oyezera a gulugufe amatha kuyikidwa mu mzere wopingasa, woyimirira kapena wopendekera.
Valavu yoyesera ya diaphragm ndi yoyenera paipi yolumikizira madzi yosavuta kupanga, diaphragm ikhoza kukhala yabwino kwambiri pochotsa kugwedezeka kwa madzi kwapakati. Chifukwa kutentha kogwira ntchito ndi kukakamizidwa kwa valavu yoyesera ya diaphragm kumakhala kochepa chifukwa cha zinthu za diaphragm, nthawi zambiri imagwiritsidwa ntchito mu chitoliro chotentha chotsika, makamaka choyenera chitoliro chamadzi. Kutentha kogwira ntchito kwapakati pakati pa -20~120℃, kuthamanga kogwira ntchito <1.6mpa, koma valavu yoyesera ya diaphragm imatha kuchita mainchesi akulu, DN mpaka 2000mm pamwamba.
Valavu yowunikira ya diaphragm chifukwa cha magwiridwe ake abwino osalowa madzi, kapangidwe kake kosavuta, mtengo wotsika wopanga, kotero m'zaka zaposachedwa, ntchito zambiri zimagwiritsidwa ntchito.
Popeza chisindikizocho ndi mpira wokutidwa ndi rabala, valavu yowunikira mpira imakhala ndi magwiridwe antchito abwino otsekera, ntchito yodalirika komanso kukana bwino kugunda kwa madzi. Ndipo chifukwa chisindikizocho chingakhale mpira umodzi, ndipo chingapangidwe kukhala mipira yambiri, kotero chingapangidwe kukhala caliber yayikulu. Koma chisindikizo chake ndi chophimbidwa ndi mpira wopanda kanthu, sichiyenera mapaipi amphamvu kwambiri, chimayenera mapaipi apakati ndi otsika mphamvu.
Popeza chigoba cha valavu yozungulira chingapangidwe ndi chitsulo chosapanga dzimbiri, ndipo chigoba chopanda kanthu cha chisindikizocho chikhoza kuphimbidwa ndi mapulasitiki a polytetrafluoroethylene engineering, chingagwiritsidwenso ntchito popangira zinthu zowononga.
Mtundu uwu wa kutentha kwa ntchito ya valavu yoyezera ndi pakati pa -101 ℃ ndi 150 ℃, kuthamanga kwake kwapadera ndi ≤4.0MPa, ndipo m'mimba mwake ndi pakati pa 200 ~ 1200mm.
Nortech ndi m'modzi mwa opanga ma valve otsogola ku China omwe ali ndi satifiketi ya ISO9001 yapamwamba.
Zinthu zazikulu:Valavu ya Gulugufe,Valavu ya Mpira,Valavu ya Chipata,Valavu Yowunikira,Globe Vavlve,Zipangizo za Y,Chotsukira Magetsi,Zipangizo zoyezera mpweya (Pneumatic Acurators).
