Valve ndi zida zomwe zimagwiritsidwa ntchito kwambiri zomwe zimapezeka pafupifupi kulikonse, mavavu amagwira ntchito m'misewu, nyumba, magetsi ndi mphero zamapepala, zoyeretsera, ndi zomangamanga zosiyanasiyana ndi mafakitale.
Ndi mafakitale ati asanu ndi awiri omwe mavavu amagwiritsidwa ntchito kwambiri komanso momwe amagwiritsira ntchito ma valve:
1. Makampani opanga magetsi
Makina ambiri opangira magetsi amagwiritsa ntchito mafuta oyambira pansi komanso ma turbines othamanga kwambiri kuti apange magetsi.Ma valve a zipataamasankhidwa kuti azimitsa / kuzimitsa magetsi.Nthawi zina ma valve ena amagwiritsidwa ntchito, mongaY mavavu a globe.
Kuchita bwino kwambirima valve a mpiraamagwiritsidwa ntchito kwambiri m'makampani opanga magetsi.
Ntchito zopangira magetsi zimayika mapaipi ndi mavavu pansi pazovuta kwambiri, kotero mavavu amafunikira zida zolimba ndi mapangidwe kuti athe kupirira mayeso angapo, kutentha, ndi kupsinjika.
Kuphatikiza pa valavu yayikulu ya nthunzi, malo opangira magetsi ali ndi mapaipi angapo othandizira.Mapaipi othandizira awa amakhala ndi mitundu yosiyanasiyanama valve a globe, valavu butterfly, fufuzani ma valve, ma valve a mpirandima valve pachipata.
2. Madzi amagwira ntchito
Zomera zam'madzi zimafuna kutsika kwamphamvu komanso kutentha kozungulira.
Chifukwa kutentha kwa madzi ndi kutentha kwa chipinda, zosindikizira za rabara ndi ma elastomer omwe sali oyenera kwina kulikonse angagwiritsidwe ntchito.Zida zamtunduwu zimatha kukwaniritsa kuyika kosindikizidwa kwa mavavu amadzi kuti asatayike.
Mavavu m'madzi amadzi nthawi zambiri amakhala ndi zokakamiza pansi pa 200psi, chifukwa chake, sipakufunika kuthamanga kwambiri, kapangidwe kake ka khoma.Pokhapokha ngati mukufunikira kugwiritsa ntchito valavu pamtunda wothamanga kwambiri m'damu kapena mumsewu wautali wamadzi, valavu yamadzi yomangidwira ingafunikire kupirira kupanikizika kwa 300psi.
3. Makampani akunyanja
Dongosolo la mapaipi a malo opangira zinthu zam'mphepete mwa nyanja ndi nsanja zoboola mafuta zili ndi kuchuluka kwamavavu.Ma valve awa ali ndi mitundu yosiyanasiyana yomwe imatha kuthana ndi mavuto onse oyendetsa.
Gawo lofunikira kwambiri pazopangira mafuta ndi gasi wachilengedwe kapena mapaipi obwezeretsa mafuta.Dongosololi silimangogwiritsidwa ntchito papulatifomu, njira yake yopangira nthawi zambiri imagwiritsidwa ntchito pamtunda wa 10,000 kapena kuya kwambiri.
Pamapulatifomu akuluakulu amafuta, mafuta ochulukirapo amafunikira kuchokera pachitsime.Njirazi ndi monga kulekanitsa gasi ( gasi wachilengedwe ) kuchokera ku nthunzi yamadzimadzi komanso kulekanitsa madzi ku ma hydrocarbon.
Machitidwewa nthawi zambiri amagwiritsa ntchitoma valve a mpirandifufuzani ma valvendiAPI 6D mavavu pachipata. Mavavu a API 6Dsali oyenera ntchito ndi zofunika okhwima pa mapaipi, ndipo zambiri ntchito m'mapaipi m'nyumba pa zombo kubowola kapena nsanja.
4. Kusamalira madzi oipa
Mapaipi amadzi otayira amasonkhanitsa zinthu zotayidwa ndi zamadzimadzi ndikuzitsogolera kumalo osungira madzi oipa.Malo opangira zimbudzi amagwiritsa ntchito mapaipi ocheperako komanso ma valve kuti agwire ntchito.Nthawi zambiri, zofunikira zama valve amadzi otayirira zimakhala zomasuka kuposa zamadzi oyera.
Onani ma valvendizipata zachitsulondizo zisankho zodziwika kwambiri pakutsuka madzi oyipa.
5. Kupanga mafuta ndi gasi
Zitsime za gasi ndi zitsime zamafuta ndi malo awo opangira zimagwiritsa ntchito ma valve ambiri olemera.Gasi wapansi panthaka ndi mafuta ali ndi mphamvu zambiri, mafuta ndi gasi amatha kupopera mumlengalenga mamita 100 pamwamba.
Kuphatikizika kwa ma valve ndi zida zapadera zimatha kupirira kupsinjika pamwamba pa 10,000 psi.Kupsyinjika kumeneku sikuchitika kawirikawiri pamtunda ndipo kumakhala kofala kwambiri m'zitsime zamafuta zakuya.
Mavavu a zida zachitsime amatha kutentha kwambiri komanso kuthamanga kwambiri.Mavavu ophatikizira mapaipi nthawi zambiri amakhala ndi apaderama valve a globe(otchedwa throttle valves) ndima valve pachipata.A wapaderavalavu yoyimitsaamagwiritsidwa ntchito kuwongolera kutuluka kwa chitsime.
Kuwonjezera pa chitsime, palinso zipangizo zomwe zimafuna ma valve mu gasi ndi minda yamafuta.Izi zimaphatikizapo zida zopangira mafuta achilengedwe kapena gasi.Ma valve awa nthawi zambiri amapangidwa ndi chitsulo chotsika cha carbon.
6. Mapaipi
Ma valve ambiri ofunikira amagwiritsidwa ntchito m'mapaipi awa : mwachitsanzo, ma valve oyimitsa mapaipi mwadzidzidzi.Valavu yodzidzimutsa imatha kusiyanitsa chitoliro kuti chikonze kapena kutayikira.
Palinso malo omwazikana m'mphepete mwa payipi : apa ndi pamene payipi imawululidwa pansi, izi ndizo zida zomwe zimagwiritsidwa ntchito poyang'anira ndi kuyeretsa mzere wopanga.Masiteshoniwa amakhala ndi ma valve angapo, omwe nthawi zambiri amakhalama valve a mpira or ma valve pachipata.Vavu yapaipi iyenera kukhala yotseguka mokwanira kuti zida zotulutsa ngalande zidutse.
7. Nyumba zamalonda
Pali mipope yambiri m'nyumba zamalonda zomwe zaima.Kupatula apo, nyumba iliyonse imafunikira madzi ndi magetsi.Pamadzi, payenera kukhala njira zosiyanasiyana zamapaipi onyamula madzi, madzi otayira, madzi otentha ndi zida zotetezera moto.
Kuonjezera apo, kuti chitetezo cha moto chizigwira ntchito bwino, chiyenera kukhala ndi mphamvu zokwanira.Mtundu ndi gulu la valavu ya msonkhano wa moto uyenera kuvomerezedwa ndi bungwe loyang'anira lolingana lisanakhazikitsidwe.
