Posachedwapa, ntchito yokonza zinthu inamalizidwa mu workshop ya Jinbin: avalavu yodulira damper ya njira zitatuValavu iyi ya damper ya njira zitatu imapangidwa ndi chitsulo cha kaboni ndipo ili ndi ma actuator opumira mpweya. Achita kafukufuku wambiri wa khalidwe ndi mayeso a switch ndi ogwira ntchito ku Jinbin ndipo atsala pang'ono kupakidwa ndi kutumizidwa.

Valavu yopopera mpweya yowongolera mbali zitatu ndi gawo lowongolera lomwe limasintha njira yapakati kudzera mu kayendedwe ka pakati pa valavu. Kapangidwe kake kapakati kamakhala ndi ma interface atatu (nthawi zambiri amadziwika kuti A, B, ndi C) ndi pakati pa valavu yosunthika, yomwe imatha kuyendetsedwa pamanja, mothandizidwa ndi mpweya, kapena ndi magetsi. Pakugwira ntchito, pakati pa valavu pamasintha malo ake olumikizirana ndi thupi la valavu potembenuza kapena kuzungulira: pamene pakati pa valavu pamakhala pamalo oyamba, zingayambitse kuti doko A ndi Port B zilumikizidwe ndipo doko C litsekedwe. Mukasinthira kumalo ena, zimakhala kuti doko A ndi Port C zilumikizidwe pamene doko B latsekedwa. Mitundu ina imathanso kulumikiza doko B ndi Port C pamene doko A latsekedwa, motero kumaliza mwachangu kusintha kwa kayendedwe ka kayendedwe ka madzi, kulumikizana kapena kusintha kwa sing'anga (madzi, gasi kapena nthunzi).

Mtundu uwu wa valavu uli ndi ubwino waukulu: Choyamba, uli ndi kapangidwe kakang'ono. Vavu imodzi imatha kulowa m'malo mwa ntchito yophatikizana ya mavavu angapo a mbali ziwiri, zomwe zimapangitsa kuti kapangidwe ka mapaipi kakhale kosavuta komanso kusunga malo oyika. Chachiwiri, imakhala ndi yankho lofulumira. Kuyenda kwa pakati pa valavu yochepetsera mpweya kumasintha mwachindunji njira popanda kufunikira kowongolera kovuta, motero kumawonjezera magwiridwe antchito a dongosololi.

Chachitatu, ili ndi magwiridwe antchito odalirika otsekera. Kugwirizana kolondola pakati pa valavu ndi thupi la valavu kumatha kuchepetsa kutuluka kwapakati ndikusinthasintha kuti igwire ntchito molimbika monga kuthamanga kwambiri komanso kutentha kwambiri. Chachinayi, ili ndi ntchito zosiyanasiyana. Kaya ndi madzi, mafuta, gasi kapena zinthu zowononga, kuwongolera kokhazikika kumatha kuchitika posankha zipangizo zoyenera (monga chitsulo chosungunuka, chitsulo chosapanga dzimbiri).

Valavu yopopera mpweya (mavavu opopera mpweya) ndi yoyenera kwambiri pazochitika zomwe kusintha kosinthasintha kwa kayendedwe ka madzi apakati kumafunika: mwachitsanzo, mu machitidwe a HVAC, imagwiritsidwa ntchito kusinthana pakati pa madzi ozizira ndi otentha apakati kuti azitha kutentha mkati. Mu ntchito zamafakitale, kuwongolera kusintha kwapakati kapena kulumikizana kwa mapaipi a mankhwala ndi mafuta; Mu machitidwe a hydraulic ndi pneumatic, njira yotumizira mafuta kapena mpweya wopanikizika imasinthidwa kuti iyendetse zinthu zoyendetsera. Kuphatikiza apo, imagwiritsidwa ntchito kwambiri pazochitika monga machitidwe osonkhanitsa kutentha kwa dzuwa, mapaipi oyendera madzi, ndi machitidwe amagetsi otumiza chifukwa cha kusinthana pafupipafupi kwa njira zapakati, zomwe zingathandize kwambiri kuphatikiza ndi kugwira ntchito bwino kwa dongosololi.

Jinbin Valves, kampani yopanga ma valve ya zaka 20, imapanga ndi kupanga mapulojekiti osiyanasiyana a ma valve a zitsulo, popereka mayankho ndi ntchito zabwino kwambiri kwa makasitomala omwe akusowa thandizo padziko lonse lapansi. Ngati muli ndi mafunso okhudzana ndi izi, chonde titumizireni uthenga pansipa. Mudzalandira yankho mkati mwa maola 24. Tikuyembekezera kugwira nanu ntchito! (Wopanga Ma Valve a Damper)
