Kusiyana pakati pa zisindikizo zofewa ndi zolimba za ma valve:

Choyamba, kaya ndi valavu ya mpira kapenavalavu ya gulugufe, ndi zina zotero, pali zomangira zofewa ndi zolimba, tengerani valavu ya mpira mwachitsanzo, kugwiritsa ntchito zomangira zofewa ndi zolimba za mavalavu a mpira ndi kosiyana, makamaka mu kapangidwe kake, ndipo miyezo yopangira mavalavu si yofanana.

Choyamba, kapangidwe kake

Chisindikizo cholimba cha valavu ya mpira ndi chisindikizo chachitsulo ndi chitsulo, ndipo mpira wotsekera ndi mpando ndi chitsulo. Kulondola kwa makina ndi njira yake n'kovuta, ndipo nthawi zambiri imagwiritsidwa ntchito pamavuto akulu, nthawi zambiri kuposa 35MPa. Zisindikizo zofewa ndi zisindikizo pakati pa zitsulo ndi zosakhala zitsulo, monga nayiloni \ PTFE, ndipo miyezo yopangira ndi yofanana.

Chachiwiri, zinthu zotsekera

Chisindikizo chofewa ndi cholimba ndi zinthu zotsekera za mpando wa valavu, ndipo chisindikizo cholimba chimapangidwa molondola ndi zinthu zotsekera valavu kuti zitsimikizire kuti zikugwirizana bwino ndi maziko a valavu (mpira), nthawi zambiri chitsulo chosapanga dzimbiri ndi mkuwa. Kutsekera kofewa kumatanthauza kuti zinthu zotsekera zomwe zili mu mpando wa valavu sizinthu zachitsulo, chifukwa zinthu zotsekera zofewa zimakhala ndi kusinthasintha kwina, kotero zofunikira pakukonza molondola zidzakhala zochepa kuposa za kutsekera kolimba.

Chachitatu, njira yopangira

Chifukwa cha mafakitale ambiri a mankhwala, malo ogwirira ntchito a makampani a makina ndi ovuta kwambiri, ambiri ndi kutentha kwambiri komanso kuthamanga kwambiri, kukana kukangana kwa sing'anga ndi kwakukulu, ndipo dzimbiri ndi lamphamvu, tsopano ukadaulo wapita patsogolo, kugwiritsa ntchito zipangizo zosiyanasiyana kuli bwino, ndipo kukonza ndi zina zitha kupitiliza, kotero kuti valavu ya mpira yokhala ndi chisindikizo cholimba yalimbikitsidwa kwambiri.

Ndipotu, mfundo ya valavu yolimba yotsekera mpira ndi yofanana ndi ya valavu yofewa yotsekera, koma chifukwa ndi valavu yotsekera pakati pa zitsulo, ndikofunikira kuganizira ubale wolimba pakati pa zitsulo, komanso momwe ntchito ikuyendera, njira yoti igwiritsidwire ntchito, ndi zina zotero. Nthawi zambiri, kuuma kumafunika, ndipo mpira ndi mpando zimaphwanyidwa nthawi zonse kuti zigwirizane. Nthawi yopangira valavu yolimba yotsekera mpira ndi yayitali, kukonza kumakhala kovuta kwambiri, ndipo sikophweka kuchita bwino valavu yolimba yotsekera mpira.

Chachinayi, mikhalidwe yogwiritsira ntchito

Zisindikizo zofewa nthawi zambiri zimatha kufika pa zisindikizo zapamwamba, pomwe zisindikizo zolimba zimatha kukhala zapamwamba kapena zochepa malinga ndi zofunikira; Zisindikizo zofewa ziyenera kukhala zosapsa moto, chifukwa kutentha kwambiri, zinthu za chisindikizo chofewa zimatuluka, pomwe chisindikizo cholimba sichikhala ndi vutoli; Zisindikizo zolimba nthawi zambiri zimatha kupangidwa ndi mphamvu zambiri, koma zisindikizo zofewa sizingapangidwe; Chifukwa cha vuto la kuyenda kwapakati, chisindikizo chofewa sichingagwiritsidwe ntchito nthawi zina (monga zinthu zina zowononga); Valavu yomaliza yolimba nthawi zambiri imakhala yokwera mtengo kuposa valavu yofewa. Ponena za kupanga, palibe kusiyana kwakukulu pakati pa ziwirizi, chinthu chachikulu ndi kusiyana pakati pa mipando ya valavu, chisindikizo chofewa sichili chachitsulo, ndipo chisindikizo cholimba ndi chachitsulo.

Chachisanu, posankha zida

Kusankha ma valve ofewa ndi olimba kumadalira kwambiri njira yogwiritsira ntchito, kutentha ndi kupanikizika, njira yonseyi ili ndi tinthu tolimba kapena yawonongeka kapena kutentha kwake kuli kokwera kuposa madigiri 200, ndibwino kusankha ma valve olimba, m'mimba mwake ndi woposa 50, kusiyana kwa kuthamanga kwa ma valve ndi kwakukulu, ndipo mphamvu ya valavu yotsegulira imaganiziridwanso, ndipo valavu yokhazikika ya valavu yolimba iyenera kusankhidwa pamene mphamvuyo ndi yayikulu, mosasamala kanthu za ma valve ofewa ndi olimba, mulingo wotsekera ukhoza kufika pamlingo 6.

Ngati mukufuna kukhala ndi mpando wokhazikikavalavu ya gulugufe, valavu ya chipata,Chotsukira cha Y, valavu yolinganiza,valavu yoyezera, mutha kulankhulana nafe kudzera pa whatsapp kapena imelo.
