Ma valve opangidwa ndi kuponyera ndi ma valve opangidwa ndi kuponyera. Kawirikawiri, kuchuluka kwa kupanikizika kwa ma valve opangidwa ndi kuponyera ndi kochepa (monga PN16, PN25, PN40, koma palinso ena amphamvu kwambiri, omwe amatha kufika 1500Lb, 2500Lb), ndipo ma caliber awo ambiri ali pamwamba pa DN50. Ma valve opangidwa ndi kuponyera ndi opangidwa ndipo nthawi zambiri amagwiritsidwa ntchito m'mapaipi apamwamba okhala ndi ma caliber ang'onoang'ono, nthawi zambiri pansi pa DN50.
1. Kuponya
1. Kuponya: Ndi njira yosungunula chitsulo kukhala madzi yomwe imakwaniritsa zofunikira zina ndikuchitsanulira mu nkhungu. Pambuyo poziziritsa, kuuma, ndi kuyeretsa, kuponya (gawo kapena lopanda kanthu) komwe kali ndi mawonekedwe, kukula, ndi magwiridwe antchito okonzedweratu kumapezeka. Ukadaulo woyambira wamakampani opanga makina amakono.
2. Ubweya wopangidwa ndi nsalu yopangidwa ndi nsalu ndi wotsika mtengo, ndipo ukhoza kusonyeza kuti ndi wothandiza kwambiri pazigawo zokhala ndi mawonekedwe ovuta, makamaka okhala ndi mabowo ovuta mkati; nthawi yomweyo, umakhala wosinthasintha kwambiri komanso uli ndi mphamvu zambiri zogwirira ntchito.
3. Zipangizo (monga chitsulo, matabwa, mafuta, zipangizo zoyezera, ndi zina zotero) ndi zida (monga ng'anjo zachitsulo, zosakaniza mchenga, makina oumbira, makina opangira ma core, makina ogwedeza, makina ophulitsira mfuti, mbale zachitsulo zoponyedwa, ndi zina zotero) zofunika popanga zinthu zoponyera () Ndi zambiri, ndipo zimapanga fumbi, mpweya woipa ndi phokoso ndikuipitsa chilengedwe.
4. Kuponya ndi mtundu wa ukadaulo wopangira kutentha kwachitsulo womwe anthu adaphunzira kale, wokhala ndi mbiri ya zaka pafupifupi 6000.
Mu 3200 BC, kupangidwa kwa achule a mkuwa kunayamba ku Mesopotamia. Pakati pa zaka za m'ma 1300 BC ndi zaka za m'ma 100 BC, China yalowa mu nthawi yopangidwa kwa achule a mkuwa.
Luso la zinthu lafika pamlingo wapamwamba kwambiri, monga Simuwu Fangding Ding yolemera makilogalamu 875 kuchokera ku Shang Dynasty, mbale ya Zenghou Yizun kuchokera ku Warring States Period, ndi galasi lowala kuchokera ku Western Han Dynasty zonse zikuyimira kupangidwa kwa zinthu zakale.
Kuumba koyambirira kunakhudzidwa kwambiri ndi mbiya, ndipo zinthu zambiri zomwe zinkapangidwa zinali zida kapena ziwiya zogwirira ntchito zaulimi, chipembedzo, ndi moyo.
Utoto wake ndi wamphamvu kwambiri. Mu 513 BC, China idapanga zida zoyamba padziko lonse lapansi zoyezera zitsulo (zolemera pafupifupi makilogalamu 270), zomwe zimapezeka m'mabuku olembedwa.
Cha m'ma 800, ku Ulaya kunayamba kupanga zitsulo zoyeretsera. Pambuyo pa kusintha kwa mafakitale m'zaka za m'ma 1700, zitsulo zoyeretsera zinayamba kugwiritsidwa ntchito m'mafakitale akuluakulu.
M'zaka za m'ma 1900, chitukuko chachangu cha kupangira zinthu zopangidwa ndi chitsulo chapangidwa. Chitsulo chopangidwa ndi nodular, chitsulo chopangidwa ndi chitsulo chosakanizika, chitsulo chosapanga dzimbiri cha carbon chochepa kwambiri, mkuwa wa aluminiyamu, silicon ya aluminiyamu, ndi zitsulo zopangidwa ndi aluminium-magnesium zapangidwa motsatizana.
Kupangira zinthu zachitsulo monga titaniyamu ndi nikeli, ndipo adapanga njira yatsopano yopangira chitsulo choyera. Pambuyo pa zaka za m'ma 1950, chitsanzo cha mchenga wonyowa chothamanga kwambiri chinawonekera,
Kupanga chitsanzo cha mchenga wolimba ndi mankhwala, kupanga chitsanzo cha kupanikizika koipa, kuponyera kwina kwapadera, kuphulitsa mfuti ndi ukadaulo wina watsopano.
5. Pali mitundu yambiri ya kuponyera, yomwe imagawidwa m'magulu awa: ①Kuponyera mchenga wamba, kuphatikiza mitundu itatu ya mchenga wobiriwira, mchenga wouma ndi mchenga wolimba ndi mankhwala. ②Kuponyera kwapadera, malinga ndi zinthu zojambulira, kungagawidwe m'magulu awiri: kuponyera kwapadera ndi mchenga wamchere wachilengedwe ndi miyala ngati zinthu zazikulu zojambulira (monga kuponyera ndalama, kuponyera dongo, kuponyera chipolopolo cha workshop, kuponyera kopanikizika koipa, kuponyera kolimba, kuponyera kwa ceramic) ndi zina zotero) ndi kuponyera kwapadera ndi chitsulo ngati zinthu zazikulu zojambulira (monga kuponyera nkhungu yachitsulo, kuponyera kopanikizika, kuponyera kosalekeza, kuponyera kotsika, kuponyera kwa centrifugal, ndi zina zotero).
6. Njira yopangira zinthu nthawi zambiri imaphatikizapo: ①Kukonzekera zinthu zopangidwa ndi nkhungu (zotengera zomwe zimapanga zitsulo zamadzimadzi kukhala zinthu zolimba). Zinthu zopangidwa ndi nkhunguzo zitha kugawidwa m'magulu monga mchenga, chitsulo, ceramic, dongo, graphite, ndi zina zotero, malinga ndi kuchuluka kwa nthawi zomwe zagwiritsidwa ntchito. Pazinthu zotayidwa, zosakhalitsa komanso zosatha, ubwino wa kukonzekera nkhungu ndiye chinthu chachikulu chomwe chimakhudza ubwino wa zinthu zopangidwa ndi nkhunguzo; ②Kusungunuka ndi kuthira zitsulo zopangidwa ndi nkhungu, zitsulo zopangidwa ndi nkhungu (zopangira zinthu zopangidwa ndi nkhungu) makamaka zimaphatikizapo chitsulo chosungunuka, chitsulo chosungunuka ndi zinthu zopanda chitsulo zopangidwa ndi nkhungu; ③ Kukonza ndi kuyang'anira zinthu zopangidwa ndi nkhungu. Kukonza zinthu zopangidwa ndi nkhungu kumaphatikizapo kuchotsa zinthu zakunja pakati ndi pamwamba pa zinthu zopangidwa ndi nkhunguzo, kuchotsa zinthu zothira, kufoshola ma burrs ndi ma drape seams, komanso kutentha, kupanga mawonekedwe, kuchiza dzimbiri ndi makina okhwima. Valavu yolowetsa pampu

Nortech ndi m'modzi mwa opanga ma valve otsogola ku China omwe ali ndi satifiketi ya ISO9001 yapamwamba.

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).
