Mavavu a slab ndi zinthu zofunika kwambiri pamakampani osiyanasiyana, makamaka omwe amakhudza kuwongolera kutuluka kwamadzi kapena mpweya.Ma valve awa amagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo kupanga mafuta ndi gasi, kukonza mankhwala, ndi kuyeretsa madzi.M'nkhaniyi, tiwona zomwe ma valve a slab ali, momwe amagwirira ntchito, ndi mitundu yawo yosiyanasiyana.
Kodi avalavu ya slab?
Valavu ndi mtundu wa valavu yomwe imakhala ndi chipata chophwanyika kapena chofanana ndi slab chomwe chimatsetsereka kuti chizitha kuyendetsa madzi kapena gasi kudzera mupaipi.Chipata nthawi zambiri chimapangidwa ndi chitsulo ndipo chimagwiritsidwa ntchito ndi actuator, yomwe imatha kukhala yamanja, hydraulic, kapena pneumatic.Chipata chikakhala chotsekeka, chimatsekereza kutuluka kwa madzimadzi, ndipo chikatseguka, chimalola madzi kudutsa.
Kodi avalavu ya slabntchito?
Mfundo yogwirira ntchito ya valve ya slab ndiyosavuta.Pamene actuator yatsegulidwa, imayendetsa chipata mmwamba kapena pansi, malingana ndi ngati valve iyenera kutsegulidwa kapena kutsekedwa.Pamalo otsekedwa, chipata chimamangirira valavu, ndikupanga chisindikizo cholimba chomwe chimalepheretsa madzi kuyenda mupaipi.Vavu ikafunika kutsegulidwa, chowongolera chimasuntha chipatacho, ndikupangitsa kuti madzi aziyenda momasuka kudzera mupaipi.
Ma valve a slab nthawi zambiri amagwiritsidwa ntchito pomwe madzi ambiri amafunikira kusunthidwa mwachangu.Amagwiritsidwa ntchito makamaka pogwiritsira ntchito pamene madziwa amawombera kapena akuwononga, chifukwa chipatacho chikhoza kupangidwa ndi zipangizo zomwe zimagonjetsedwa ndi kuvala.
Mitundu ya mavavu a slab
Pali mitundu ingapo ya mavavu a slab, iliyonse ili ndi mawonekedwe akeake komanso magwiridwe antchito.Zina mwa mitundu yodziwika bwino ndi izi:
Valavu ya slab yokwera: Mtundu uwu wa valavu uli ndi chipata chomwe chimayenda mmwamba ndi pansi motsatira tsinde la ulusi.Pamene tsinde likuzungulira, chipata chimayenda mmwamba kapena pansi, kutsegula kapena kutseka valve.
Valavu ya tsinde yosakwera: Vavu yamtunduwu imakhala ndi chipata chomwe chimayenda mmwamba ndi pansi motsatira tsinde lopanda ulusi.M'malo mozungulira tsinde, actuator imasuntha chipata mmwamba kapena pansi mwachindunji, kutsegula kapena kutseka valve.
Valavu yachipata cha mpeni: Valavu yamtunduwu imakhala ndi chipata chakuthwa chakuthwa chomwe chimadula madziwo pamene chikukwera ndi kutsika.Ma valve pachipata cha mpeni nthawi zambiri amagwiritsidwa ntchito pomwe madziwa amakhala ndi tinthu tolimba, monga migodi kapena kuthira madzi oyipa.
Vavu yolowera pachipata: Valovu yamtunduwu imakhala ndi chipata chomwe chimalowera mmbuyo ndi mtsogolo osati m'mwamba ndi pansi.Ma valve olowera pachipata nthawi zambiri amagwiritsidwa ntchito ngati chosindikizira cholimba, monga mapaipi a gasi.
Vavu yolowera pachipata: Mtundu uwu wa vavu uli ndi chipata chopangidwa ngati mphero.Pamene chipata chikutsitsidwa, chimakanikiza mpando wa valve, kupanga chisindikizo cholimba chomwe chimalepheretsa madzi kuyenda.
Kusankha valavu yoyenera pakugwiritsa ntchito kwanu
Posankha valavu ya slab kuti mugwiritse ntchito, pali zinthu zingapo zomwe muyenera kuziganizira, kuphatikizapo mtundu wamadzimadzi omwe amanyamulidwa, kuthamanga ndi kutentha kwa madzi, komanso kuthamanga kwa madzi.Ndikofunika kusankha valavu yomwe imapangidwa kuchokera kuzinthu zomwe zimagwirizana ndi madzi omwe amanyamulidwa, komanso valavu yomwe imatha kupirira kuthamanga ndi kutentha kwa madzi.
Kuphatikiza apo, ndikofunikira kusankha valavu yomwe ili yoyenera pakugwiritsa ntchito kwanu.Kusankha valavu yomwe ili yaying'ono kwambiri kungayambitse kutsika kwamphamvu kwambiri ndi zoletsa kuyenda, pamene kusankha valve yomwe ili yaikulu kwambiri kungapangitse ndalama zowonjezera komanso kuchepetsa mphamvu.
Mapeto
Ma valve a slabndi zigawo zofunika m'njira zambiri zamafakitale, zomwe zimapereka kuwongolera bwino kwamadzimadzi kudzera m'mapaipi.Ndi mapangidwe awo ophweka ndi ntchito yodalirika, ma valve a slab ndi abwino kuti agwiritsidwe ntchito pazinthu zosiyanasiyana, kuchokera ku mafuta ndi gasi kupanga.
kukonza mankhwala ndi mankhwala madzi.Pomvetsetsa mitundu yosiyanasiyana ya ma valve a slab ndi zinthu zomwe muyenera kuziganizira posankha valavu yoyenera pa ntchito yanu, mukhoza kuonetsetsa kuti ndondomeko yanu ikuyenda bwino.
Ndikofunikiranso kusunga bwino ma valve anu a slab kuti muwonetsetse kuti akugwirabe ntchito komanso kudalirika.Kuyang'anitsitsa ndi kukonza nthawi zonse kungathandize kuzindikira zovuta zilizonse zomwe zingakhalepo zisanakhale zovuta zazikulu, kuteteza kutsika kwa nthawi ndi kukonza zodula.
Pomaliza, ma valve a slab ndi gawo lofunikira pazantchito zambiri zamakampani, zomwe zimapereka kuwongolera kodalirika komanso kolondola pakuyenda kwamadzi.Posankha valavu yoyenera pa ntchito yanu ndikuyisunga bwino, mukhoza kuonetsetsa kuti ndondomeko yanu ikuyenda bwino, kukulitsa zokolola ndikuchepetsa nthawi yopuma.
