Mu malo ochitira masewera a Jinbin, gulu la ma valve a gulugufe olimba otsekedwa bwino okhala ndi mipata itatu likuyembekezeka kutumizidwa, okhala ndi kukula kuyambira DN65 mpaka DN400.valavu ya gulugufe yozungulira katatundi valavu yozimitsa yogwira ntchito bwino kwambiri. Ndi kapangidwe kake kapadera komanso mfundo yogwirira ntchito, ili ndi malo ofunikira m'magawo ambiri amafakitale. Kapangidwe kake ka "zinthu zitatu zachilendo" ndiye chinthu chachikulu chomwe chimapangitsa kuti pakhale kapangidwe kake:valavu yolimba yotsekera gulugufeMzere woyambira umapatuka pakati pa mbale ya gulugufe komanso pakati pa thupi la valavu, ndipo nthawi yomweyo, mzere wapakati wa pamwamba pa conical wotsekereza uli ndi mawonekedwe a ngodya yosiyana poyerekeza ndi mzere wapakati wa payipi.

Kapangidwe kameneka kamaswa lamulo loyendera ma valve achikhalidwe a gulugufe. Valvu ikatsegulidwa, mbale ya gulugufe ndi mpando wa valavu zimachotsedwa nthawi yomweyo. Panthawi yotseka, mbale ya gulugufe pang'onopang'ono imayandikira mpando wa valavu, ndipo pamapeto pake imatseka kudzera mu kukanikizana kwa ma pair otchinga kapena achitsulo. Kapangidwe kameneka kamapewa bwino kukangana pakati pa mbale ya gulugufe ndi mpando wa valavu panthawi yotsegula ndi kutseka, kumawonjezera kwambiri moyo wa ntchito ya awiri otchinga, ndipo nthawi yomweyo kumachepetsa mphamvu yogwirira ntchito, zomwe zimapangitsa kuti kutsegula ndi kutseka kwa valavu kukhale komasuka komanso kosavuta.

Poyerekeza ndi mitundu ina ya ma valve, valavu ya gulugufe yolimba ya Flanged Seal ili ndi ubwino waukulu. Choyamba, ili ndi magwiridwe antchito abwino kwambiri otsekera. Kapangidwe kachitsulo kolimba kotsekera kakhoza kulephera kutayikira ndi kupirira kupsinjika mpaka 1.6MPa - 10MPa, kukwaniritsa zofunikira pamikhalidwe yosiyanasiyana yogwirira ntchito yopanikizika kwambiri. Kachiwiri, imakhala ndi mphamvu yolimba yolimbana ndi dzimbiri. Imapangidwa ndi zinthu zapadera zolimba kapena chitsulo chosapanga dzimbiri ndipo imatha kugwirabe ntchito mokhazikika m'malo ovuta monga kutentha kwambiri, kuthamanga kwambiri komanso dzimbiri lamphamvu. Kachitatu, imakhala ndi moyo wautali wogwirira ntchito. Chifukwa cha kuchepa kwa kuwonongeka pakati pa zigawo, nthawi yake yogwirira ntchito imatha kufika zaka zoposa 10 pansi pamikhalidwe yabwinobwino yogwirira ntchito, zomwe zimachepetsa kwambiri ndalama zokonzera. Chachinayi, ndi yosavuta kugwiritsa ntchito ndipo imatha kuyendetsedwa m'njira zosiyanasiyana monga pamanja, zamagetsi ndi pneumatic, kukwaniritsa zofunikira zowongolera zokha m'mikhalidwe yosiyanasiyana.

Mu ntchito zenizeni, valavu ya gulugufe yolimba yotsekedwa bwino imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Mu gawo la petrochemicals, imagwiritsidwa ntchito kuwongolera mayendedwe azinthu monga mafuta, gasi wachilengedwe ndi zinthu zopangira mankhwala; Mu makampani opanga magetsi, kuyenda kwa zinthu monga nthunzi ndi madzi ozizira kumatha kusinthidwa kuti zitsimikizire kuti zida zopangira magetsi zikugwira ntchito bwino. Mu makampani opanga zitsulo, imagwiritsidwa ntchito pamakina a mapaipi azinthu monga mpweya wa blast furnace, mpweya, ndi nayitrogeni. Mu ntchito zoperekera madzi ndi zotulutsira madzi, nthawi zambiri imagwiritsidwa ntchito podula ndi kulamulira kuyenda kwa mapaipi m'mafakitale operekera madzi ndi zimbudzi m'mizinda.

Ponena za zida zogwiritsira ntchito, valavu ya gulugufe ya China yokhala ndi ma triple eccentric imagwirizana kwambiri. Ponena za zida zogwiritsira ntchito mpweya, ingagwiritsidwe ntchito pa gasi wachilengedwe, gasi wa malasha, mpweya, nayitrogeni, nthunzi, ndi zina zotero. Ponena za zida zogwiritsira ntchito madzi, imatha kugwira mafuta, mankhwala, zimbudzi, madzi a m'nyanja, ndi zina zotero. Kuphatikiza apo, pa zida zosakaniza zina zosakaniza za gasi kapena madzi zomwe zili ndi tinthu ndi fumbi, valavu iyi imathanso kugwira bwino ntchito, kusonyeza kusinthasintha kwabwino.
