Posachedwapa, ku malo ochitira masewera a Jinbin Valve, ma valve awiri akuluakulu amagetsi okhala ndi njira zitatu okhala ndi DN1400 ndi zinthu za Q235B amaliza kuwunika kwathunthu kwa fakitale ndipo ali okonzeka kutumizidwa kwa makasitomala. Ma valve awa apambana mayeso okhwima a hydrostatic pressure popanda kutayikira konse, ndipo ma actuator amagetsi amagwira ntchito bwino akangoyamba kugwira ntchito. Pakadali pano, akumalizidwa bwino kuti awonetsetse kuti akugwiritsidwa ntchito bwino.

Valavu yamagetsi ya gulugufe ya njira zitatu iyi ndi chipangizo chowongolera chapakati chomwe chapangidwira makina akuluakulu otumizira madzi. Thupi lalikulu limapangidwa ndi chitsulo cha kaboni cha Q235B, chomwe chili ndi mphamvu yabwino kwambiri yomangira, kukana kugwedezeka komanso mphamvu yonyamula kupanikizika. Ndi yoyenera mikhalidwe yogwirira ntchito ya DN1400 yayikulu, kukwaniritsa zosowa za kutumiza madzi ambiri m'malo monga madzi ndi ngalande, maukonde a mapaipi a m'matauni, ndi madzi ozungulira mafakitale. Valavuyi imagwiritsa ntchito kapangidwe kotseka ka magawo atatu, ndipo pamwamba pake potsekapo pamapangidwa ndi zinthu zosawonongeka komanso zosagwira dzimbiri, zomwe sizimangochepetsa kuwonongeka potsegula ndi kutseka, komanso zimapangitsa kuti pakhale kutseka kosataya madzi kwa nthawi yayitali, kusunga kutseka kodalirika ngakhale pansi pa kupanikizika kwakukulu komanso mikhalidwe yayikulu yosiyana. Yokhala ndi ma actuator amagetsi ogwira ntchito kwambiri, imathandizira njira zowongolera zokha zakutali komanso njira zogwirira ntchito pamanja, zomwe zimathandiza kusintha molondola, kulumikizana ndi kayendedwe ka madzi m'mapaipi a njira zitatu, kukonza bwino kwambiri magwiridwe antchito a dongosolo ndikuchepetsa ndalama zogwirira ntchito ndi kukonza pamanja.

Mu gawo loyang'anira fakitale, gulu laukadaulo limatsatira mosamalitsa miyezo yamakampani kuti lichite mayeso otsekera a hydrostatic pa ma valve, popanda kutuluka kapena kusinthika konse, ndipo magwiridwe antchito otsekera amakwaniritsa muyezo wopanda kutayikira. Nthawi yomweyo, ma round angapo otsegulira ndi kutseka amachitidwa pa ma actuator amagetsi kuti atsimikizire mokwanira kulondola kwawo kwa sitiroko, liwiro loyankha, chitetezo choletsa komanso ntchito zoteteza kupitirira muyeso, kuonetsetsa kuti magwiridwe antchito ndi okhazikika pansi pa mikhalidwe yovuta yogwirira ntchito. Mu gawo lomaliza mawonekedwe, ogwira ntchito amachita kuwunika kwathunthu, kupera ndi kupaka utoto pazinthu monga chophimba thupi la valve, pamwamba pa flange sealing, ndi ma block a actuator terminal, kuonetsetsa kuti mawonekedwe ndi magwiridwe antchito a chinthucho akukwaniritsa miyezo, ndikukwaniritsa zofunikira za makasitomala pazida zapamwamba zamafakitale.

Ndi ubwino waukulu monga njira yoyendera madzi yayikulu, kusinthana kosinthasintha komanso kulamulira kokha, mavalavu amagetsi a gulugufe a njira zitatu amagwiritsidwa ntchito kwambiri popereka madzi ndi ngalande za m'matauni, kukonza zimbudzi, madzi ozungulira fakitole yamagetsi, kutumiza madzi amadzimadzi a mankhwala, kupanga zitsulo ndi migodi ndi madera ena. Valavu imodzi imatha kulowa m'malo mwa mavalavu a gulugufe ambiri achikhalidwe, zomwe zimapangitsa kuti pakhale kusinthasintha kwakukulu pakupanga mapaipi, kuchepetsa kugwiritsa ntchito mphamvu zamagetsi komanso ndalama zokonzera pambuyo pake, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri pakukweza makina akuluakulu amadzimadzi mwanzeru komanso moyenera.

(chithunzi: DN1400 cholumikizira magetsi cha njira zitatu cha gulugufe)

Monga wopanga ma valve wokhala ndi zaka 20 zakuchitikira, Jinbin Valves yadzipereka kupatsa makasitomala zinthu zodalirika za ma valve ndi mayankho okonzedwa mwamakonda. Kuti mudziwe zambiri za ma valve amagetsi amitundu itatu a gulugufe akuluakulu, kapena zofunikira pakugwira ntchito mwamakonda, chonde funsani gulu lathu laukadaulo pansipa.
