Valavu yoyimitsa yachitsulo chosapanga dzimbiri ndi mtundu wa valavu yoyimitsa ya globe, zofunikira pa thupi la valavu ndi zapamwamba kwambiri 301.304.316 ndipo zipangizo zina zimagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, kutumiza katundu, mankhwala, makina azakudya ndi mafakitale ena. Valavu yoyimitsa yachitsulo chosapanga dzimbiri imagawidwa m'magulu awiri: valavu yoyimitsa yachitsulo chosapanga dzimbiri yamanja, valavu yoyimitsa yachitsulo chosapanga dzimbiri ya pneumatic, valavu yoyimitsa yachitsulo chosapanga dzimbiri yamagetsi.
Mfundo yogwirira ntchito ya valavu yapadziko lonse

Valavu yozungulira, yomwe imatchedwanso intercept, ndi imodzi mwa mavavu omwe amagwiritsidwa ntchito kwambiri, ndi yotchuka chifukwa cha kukangana pang'ono pakati pa pamwamba potseka potsegula ndi kutseka, yolimba pang'ono, kutalika kotseguka si kwakukulu, kupanga kosavuta, kukonza kosavuta, sikungoyenera kupanikizika pang'ono, komanso koyenera kupanikizika kwambiri.

Mfundo yotsekera ya valavu yozungulira ndi kudalira kupanikizika kwa bala ya valavu kuti pamwamba pa valavu yotsekera ndi pamwamba pa mpando wa valavu zigwirizane bwino kuti zisapitirire kuyenda kwa zinthu zolumikizira.

Valavu yozungulira imalola kuyenda kwa media kupita mbali imodzi yokha. Kutalika kwa kapangidwe ka valavu yozungulira ndi kwakukulu kuposa valavu yolowera, ndipo kukana kwamadzimadzi ndi kwakukulu, ndipo kudalirika kotseka sikolimba ikagwira ntchito kwa nthawi yayitali.
Kugawa ma valve a globe
Njira yoyimitsa valavu

1. Malinga ndi njira yoyendetsera valavu ya dziko lonse, ikhoza kugawidwa m'magulu awa:

1) valavu yoyimitsa yolunjika

2) valavu yozungulira yolunjika: mu valavu yozungulira yolunjika kapena yooneka ngati Y, njira yoyendetsera kayendedwe ka valavu ndi njira yayikulu imalowa mu mzere wozungulira, kotero kuti kuchuluka kwa kuwonongeka kwa momwe kayendedwe ka madzi kumayendera kumakhala kochepa kuposa valavu yozungulira yokhazikika, kotero kutayika kwa kuthamanga kudzera mu valavu kumakhala kochepa mofanana.

3) Valavu ya chipolopolo cha ngodya: mu valavu ya chipolopolo cha ngodya, madziwo amangofunika kusintha njira kamodzi kokha, kotero kuti kutsika kwa mphamvu kudzera mu valavu kumakhala kochepa kuposa kapangidwe ka valavu ya chipolopolo cha ngodya.

4) Valavu ya globe ya Plunger: mtundu uwu wa valavu ya globe ndi mtundu wa valavu ya globe yachizolowezi. Mu valavu iyi, diski ndi mpando nthawi zambiri zimapangidwa motsatira mfundo ya plunger. Chopondera chopukutidwa cha diski chimalumikizidwa ndi tsinde, ndipo chisindikizocho chimazindikirika ndi mphete ziwiri zomata zokhazikika zomwe zimayikidwa pa plunger. Zisindikizo ziwiri zomata zimalekanitsidwa ndi mphete yamanja ndipo zimakanikizidwa mozungulira plunger ndi katundu woyikidwa pa bonnet ndi nati ya bonnet. Mphete yomata imatha kusinthidwa ndipo imatha kupangidwa ndi zinthu zosiyanasiyana. Vavu imagwiritsidwa ntchito makamaka "pa" kapena "kuzima", koma ili ndi mtundu wapadera wa plunger kapena mphete yapadera ndipo ingagwiritsidwenso ntchito kuwongolera kuyenda.
Malo a ulusi

2 malinga ndi malo a ulusi pa tsinde la valavu ya padziko lonse akhoza kugawidwa:

1) valavu yozungulira ya tsinde lokhala ndi ulusi: Ulusi wozungulira wa valavu yozungulira womwe uli kunja kwa thupi. Ubwino wake ndi wakuti tsinde la valavu silikuwonongeka ndi chinthu chopangidwa ndi zinthu, chosavuta kudzola, kapangidwe kake kamapezeka kwambiri.

2) Pansi pa tsinde la ulusi valavu: ulusi wa tsinde la valavu m'thupi. Ulusi wa tsinde m'mapangidwe awa umalumikizana mwachindunji ndi cholumikizira ndipo umatha kuwonongeka ndipo sunapatsidwe mafuta. Kapangidwe kameneka kamagwiritsidwa ntchito m'malo ang'onoang'ono a mainchesi ndi kutentha kochepa.

NORTECH ndi imodzi mwa makampani opanga ma valve otsogola ku China omwe ali ndi satifiketi ya ISO9001 yabwino.

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).
