Nkhaniyi ikufufuzamagawo a valavu ya chipata, ntchito zawo, zizindikiro, ndi mfundo zofunika kuziganizira posankhawopanga ma valavu a chipatakapenawogulitsamakamaka muChina, komwe zinthu zapamwamba zimakhala zopikisanamitengozimapezeka kwambiri.
Kodi Valavu ya Chipata ndi Chiyani?
A valavu ya chipataNdi valavu yoyenda molunjika yomwe imapangidwa kuti itsegule kapena kutseka bwino kayendedwe ka madzi m'mapaipi. Imagwira ntchito pochotsa "chipata" chozungulira kapena chozungulira (diski yooneka ngati wedge) kuchokera panjira ya madzi. Mavalavu a chipata amadziwika kuti ndi otsika kwambiri akatsegulidwa bwino, ndipo ndi abwino kwambiri kugwiritsidwa ntchito m'mafakitale amafuta, gasi, madzi, ndi mankhwala.
Chizindikiro cha Valavu ya Chipata
Mu schematics ya uinjiniya,chizindikiro cha valavu ya chipataChimaimiridwa ndi chithunzi chosavuta: ma triangles awiri akuloza wina ndi mnzake ndi mzere woyima wowalekanitsa. Chizindikirochi chimathandiza mainjiniya ndi akatswiri kuzindikira mwachangu mitundu ya ma valavu mkati mwa makina ovuta a mapaipi.
Mbali za Valavu ya Chipata Cha Key ndi Ntchito Zake
Kumvetsetsamagawo a valavu ya chipatandikofunikira kwambiri pakukonza ndi kugula. Nazi zinthu zazikulu zomwe ziyenera kuganiziridwa:
1. Thupi: Kapangidwe kake kamakhala ndi ziwalo zamkati, zomwe nthawi zambiri zimapangidwa ndi chitsulo chosungunuka, chitsulo chosapanga dzimbiri, kapena mkuwa.
2. Boneti: Yolumikizidwa ku thupi, imaphimba tsinde ndipo imapereka chisindikizo chosatulutsa madzi.
3. Chipata (Disiki): Chotchinga chosunthika chomwe chimalamulira kuyenda kwa madzi. Mitundu yodziwika bwino ndi monga mphero, mipeni, ndi zipata zozungulira.
4. Tsinde: Amalumikiza gudumu lamanja kapena choyendetsera magetsi ku chipata, kutumiza kayendedwe kotsegula/kutseka valavu.
5. Mpando: Malo otsekera pomwe chipata chimakhazikika chikatsekedwa, kuonetsetsa kuti chimatsekedwa bwino.
6. Kulongedza: Chitseko cha gland chozungulira tsinde kuti madzi asatuluke.
7. Chiwongolero cha dzanja/Choyeretsera: Njira yogwiritsira ntchito valavu pogwiritsa ntchito manja kapena makina.
Zipangizo ndi kapangidwe ka gawo lililonse zimakhudza kulimba, kupirira kutentha, komanso kugwirizana ndi zinthu zoyatsira (monga madzi owononga).
Kusankha Wopanga kapena Wogulitsa Valve Wodalirika wa Chipata
Mukapeza ndalamamavavu a chipata, kugwirizana ndi munthu wodziwika bwinowopangakapenafakitalekumatsimikizira kudalirika kwa malonda. Nazi zomwe muyenera kuganizira:
- Ubwino wa ZinthuTsimikizirani ziphaso (monga ASTM, ISO) za zipangizo monga chitsulo chosapanga dzimbiri kapena chitsulo cha kaboni.
- Kusintha: KutsogoleraogulitsamuChinanthawi zambiri amapereka njira zopangidwira ntchito zapadera.
- Mtengo: PameneChinaOpanga omwe amagwiritsa ntchito njira zotsika mtengo amapereka njira zotsika mtengo, zomwe zimasiyanitsa mtengo ndi khalidwe.
- Miyezo YoyeseraOnetsetsani kuti ma valve akukwaniritsa miyezo ya API, ANSI, kapena miyezo ina yamakampani.
Chifukwa Chake Ma Valves a Chipata Chochokera ku China
