Vavu ya mpira yokhala ndi shaft yokhazikika pa mpira imatchedwa Vavu ya Mpira Yokwera Trunnion. Vavu ya Mpira Yokwera Trunnion imagwiritsidwa ntchito makamaka pa kuthamanga kwambiri komanso mainchesi akuluakulu. Malinga ndi kuyika kosiyana kwa mphete yotsekera mpando, Vavu ya Mpira Yokwera Trunnion ikhoza kukhala ndi mapangidwe awiri: mpando wotsekedwa patsogolo pa bwalo, ndi mpando wotsekedwa kumbuyo kwa bwalo.
1. Mbali za Trunnion Mounted Ball Valve:
1. Ntchito yotsekera ndi kutulutsa mpweya kawiri: Valavu ya Mpira Yokwera pa Trunnion imagwiritsa ntchito mpando woyandama wopangidwa ndi kasupe, mosasamala kanthu kuti valavuyo ili yotseguka kapena yotsekedwa bwino, mipando ya valavu yakumtunda ndi yakumunsi imatseka madzi, ndipo chotsalira m'thupi la valavu chimatulutsidwa kudzera mu valavu yotulutsa mpweya.
2. Ntchito yochepetsera kuthamanga kwa magazi yokha: Pamene kutentha kwa chosungira chotsalacho m'thupi la valavu kukukwera ndikupangitsa kuti kuthamanga kwa magazi kukwere kwambiri, sikuyenera kudutsa mu valavu yotetezera, koma ntchito ya mpando wa valavu imatha kuchepetsa kuthamanga kwa magazi yokha, zomwe zimapangitsa kuti valavu ikhale yotetezeka ikanyamula zinthu zamadzimadzi. Kugonana ndikofunikira kwambiri.
3. Kapangidwe ka chitetezo cha moto: Ma valve onse ali ndi ntchito zotetezera moto, ndipo kapangidwe kake ndi kupanga kwake kumatsatira zofunikira za API 607 ndi API 6FA.

1. Ntchito yotsekera ndi kutulutsa mpweya kawiri: Valavu ya Mpira Yokwera pa Trunnion imagwiritsa ntchito mpando woyandama wopangidwa ndi kasupe, mosasamala kanthu kuti valavuyo ili yotseguka kapena yotsekedwa bwino, mipando ya valavu yakumtunda ndi yakumunsi imatseka madzi, ndipo chotsalira m'thupi la valavu chimatulutsidwa kudzera mu valavu yotulutsa mpweya.
2. Ntchito yochepetsera kuthamanga kwa magazi yokha: Pamene kutentha kwa chosungira chotsalacho m'thupi la valavu kukukwera ndikupangitsa kuti kuthamanga kwa magazi kukwere kwambiri, sikuyenera kudutsa mu valavu yotetezera, koma ntchito ya mpando wa valavu imatha kuchepetsa kuthamanga kwa magazi yokha, zomwe zimapangitsa kuti valavu ikhale yotetezeka ikanyamula zinthu zamadzimadzi. Kugonana ndikofunikira kwambiri.
3. Kapangidwe ka chitetezo cha moto: Ma valve onse ali ndi ntchito zotetezera moto, ndipo kapangidwe kake ndi kupanga kwake kumatsatira zofunikira za API 607 ndi API 6FA.
2. Ubwino wa Trunnion Mounted Ball Valve:
1. Kupulumutsa mafuta otsekeredwa mwadzidzidzi: chifukwa cha zinthu zakunja zomwe zili mu sing'anga kapena moto zomwe zimapangitsa kuti chisindikizo cha mpando wa valavu chilephereke mwadzidzidzi, valavu yolowetsera mafuta imapereka kulumikizana mwachangu ndi mfuti yolowetsera mafuta, ndipo pampu yotumizidwa kunja imatha kulowetsa mafuta otsekeredwa mosavuta komanso mwachangu mu gawo lotsekerera mpando wa valavu. Kuchepetsa kutayikira.
2. Kutseka tsinde la valve yodalirika komanso mphamvu yochepa yogwirira ntchito: Kuwonjezera pa mphete yotsekera yokhazikika, chisindikizo cha O-ring chimayikidwanso pa gland yopakira. Chisindikizo chawiri chimatsimikizira kudalirika kwa chisindikizo cha tsinde la valve; kulongedza kwa graphite yowonjezera ndi mafuta otsekera. Kulowetsa kumachepetsa kutuluka kwa tsinde la valve pambuyo pa moto. Chotengera cha tsinde la valve chotsetsereka ndi chogwirira chopondereza zimapangitsa valavu kukhala yosavuta kugwiritsa ntchito.
3. M'mimba mwake wonse kapena m'mimba mwake wochepetsedwa: Kapangidwe ka m'mimba mwake wonse kapena m'mimba mwake wochepetsedwa kakhoza kusankhidwa malinga ndi zosowa. Mpata wolowera wa valavu yodzaza ndi chitoliro ndi wofanana ndi m'mimba mwake wamkati mwa payipi, zomwe ndi zosavuta kuyeretsa payipi.
4. Chitsinde cha valavu chingathe kutalikitsidwa: Malinga ndi zosowa za kukhazikitsa kapena kugwiritsa ntchito, chitsinde cha valavu chingathe kutalikitsidwa. Vavu yotalikitsidwa ya mpira wa tsinde ndi yoyenera makamaka nthawi zomwe mapaipi amafunika kukwiriridwa pansi, monga gasi wa mumzinda. Kukula kwa chitsinde chotalikitsidwacho kumatsimikiziridwa malinga ndi zosowa za makasitomala.
5. Kugwira ntchito mosinthasintha: Mpando wa valavu ndi tsinde lokhala ndi mphamvu zochepa zokangana komanso mphamvu yabwino yodzipaka mafuta zimagwiritsidwa ntchito, zomwe zimachepetsa kwambiri mphamvu yogwirira ntchito ya valavu. Chifukwa chake, ngakhale palibe mafuta otseka, valavu imatha kugwiritsidwa ntchito mosinthasintha kwa nthawi yayitali.
1. Kupulumutsa mafuta otsekeredwa mwadzidzidzi: chifukwa cha zinthu zakunja zomwe zili mu sing'anga kapena moto zomwe zimapangitsa kuti chisindikizo cha mpando wa valavu chilephereke mwadzidzidzi, valavu yolowetsera mafuta imapereka kulumikizana mwachangu ndi mfuti yolowetsera mafuta, ndipo pampu yotumizidwa kunja imatha kulowetsa mafuta otsekeredwa mosavuta komanso mwachangu mu gawo lotsekerera mpando wa valavu. Kuchepetsa kutayikira.
2. Kutseka tsinde la valve yodalirika komanso mphamvu yochepa yogwirira ntchito: Kuwonjezera pa mphete yotsekera yokhazikika, chisindikizo cha O-ring chimayikidwanso pa gland yopakira. Chisindikizo chawiri chimatsimikizira kudalirika kwa chisindikizo cha tsinde la valve; kulongedza kwa graphite yowonjezera ndi mafuta otsekera. Kulowetsa kumachepetsa kutuluka kwa tsinde la valve pambuyo pa moto. Chotengera cha tsinde la valve chotsetsereka ndi chogwirira chopondereza zimapangitsa valavu kukhala yosavuta kugwiritsa ntchito.
3. M'mimba mwake wonse kapena m'mimba mwake wochepetsedwa: Kapangidwe ka m'mimba mwake wonse kapena m'mimba mwake wochepetsedwa kakhoza kusankhidwa malinga ndi zosowa. Mpata wolowera wa valavu yodzaza ndi chitoliro ndi wofanana ndi m'mimba mwake wamkati mwa payipi, zomwe ndi zosavuta kuyeretsa payipi.
4. Chitsinde cha valavu chingathe kutalikitsidwa: Malinga ndi zosowa za kukhazikitsa kapena kugwiritsa ntchito, chitsinde cha valavu chingathe kutalikitsidwa. Vavu yotalikitsidwa ya mpira wa tsinde ndi yoyenera makamaka nthawi zomwe mapaipi amafunika kukwiriridwa pansi, monga gasi wa mumzinda. Kukula kwa chitsinde chotalikitsidwacho kumatsimikiziridwa malinga ndi zosowa za makasitomala.
5. Kugwira ntchito mosinthasintha: Mpando wa valavu ndi tsinde lokhala ndi mphamvu zochepa zokangana komanso mphamvu yabwino yodzipaka mafuta zimagwiritsidwa ntchito, zomwe zimachepetsa kwambiri mphamvu yogwirira ntchito ya valavu. Chifukwa chake, ngakhale palibe mafuta otseka, valavu imatha kugwiritsidwa ntchito mosinthasintha kwa nthawi yayitali.
Nortech ndi m'modzi mwa opanga ma valve otsogola ku China omwe ali ndi satifiketi ya ISO9001 yapamwamba.
