Mawu Oyamba

Valve yoyang'ana mkuwa kumalepheretsa kubwerera kwa madzi, mafuta, gasi, ndi madzi ena ogwirizana. Ma valve owunikira amaphatikiza zinthu zabwino kwambiri zamkuwa ndi njira zodalirika zama valavu, kuwapanga kukhala chisankho chodziwika m'mafakitale angapo.

Mfundo Yogwira Ntchito ndi Zomangamanga Zoyambira

Ma valve owunika amkuwa amalola kuti madzi aziyenda mbali imodzi pomwe akugwiritsa ntchito akasupe kapena mphamvu yokoka kuti atetezeke mobwerera. Zigawo zikuluzikulu zikuphatikizapo:

• Thupi la mkuwa ndi kapu
• Makina osindikizira amkati (zimasiyanasiyana ndi mtundu)
• Mpando ndi disc
• Kulumikizana kumatha (ulusi, flanged, kapena soldered)
• Kasupe (m'matembenuzidwe odzaza masika)

Mitundu ya Mavavu a Brass Check

1. Brass Spring Check Valve

Opelewera: Valve yowunikira yomwe imagwiritsa ntchito diski yodzaza masika kapena mbale kuti iziwongolera kuyenda, kumene kasupe amapereka mphamvu yowonjezera yotseka ndikuonetsetsa kuti kutsekedwa kwabwino motsutsana ndi kubwereranso.
Ma valve awa amakhala ndi njira yotseka yothandizidwa ndi masika yomwe imapereka:

• Nthawi yoyankha mwachangu
• Kutseka kwabwino
• Kuyika mumayendedwe aliwonse
• Nyundo yamadzi yochepetsedwa
• Ntchito yodalirika mu mizere yowongoka

2. Brass Swing FAVVA

Opelewera: Valve yoyendera yokhala ndi thupi lavavu yapadziko lonse lapansi ndi disiki yopindika mkati, kutsegula kwathunthu kulola kutsogolo kuyenda ndi kutseka motsutsana ndi mpando kuti muteteze kuyenderera mobwerera.
Chopereka chojambula chachikhalidwe:

• Kutsika kwamphamvu
• Kuthamanga kwathunthu
• Kukonza kosavuta
• Njira yothetsera ndalama
• Zabwino kwa makhazikitsidwe opingasa

3. Brass Foot Check Vavu

Opelewera: Valavu yoyang'ana yopangidwira kuyika pamizere yoyamwa pampu kapena zolowetsa mapaipi, kuphatikiza strainer yofunikira kuteteza zinyalala kuti zisalowe mudongosolo ndikusunga unidirectional flow.

• Chojambula chopangidwa ndi strainer
• Imaletsa kuthamanga kwa pampu
• Amasunga pompopompo
• Nthawi zambiri amagwiritsidwa ntchito bwino komanso ulimi wothirira

4. Brass Y-Pattern Check Valve

Opelewera: Valve yowunikira yomwe ili ndi makina osinthika osinthika omwe amayikidwa mu kapangidwe ka thupi la Y, kuphatikiza mawonekedwe a swing check valve ndi kuyendetsa bwino kwa kasinthidwe ka Y-pattern.

• Kutsika kwamphamvu kutsika poyerekeza ndi cheke chokhazikika
• Njira yosavuta yosinthira
• Yoyenera kugwiritsa ntchito nthunzi komanso kutentha kwambiri
• Mbiri yoyika yaying'ono
• Kupeza kosavuta kukonza

5. Brass Inline Check Valve

Opelewera: A chophatikizika, valavu yowunikira yowongoka yopangidwira kuti ikhazikike pamapaipi amizere, likupezeka mumitundu iwiri yosiyana yamkati:

• Mtundu Wodzaza ndi Spring: Amagwiritsa ntchito kasupe kuti atseke
• Mtundu wa Gravity: Zimadalira mphamvu yokoka ndi kuthamanga kwa backflow kuti atseke

Mapangidwe ang'onoang'ono a ntchito zopanda malo:

• Kuyika kopulumutsa malo
• Njira yosavuta yosinthira
• Kutsika kwamphamvu kutsika
• Kukonza kosavuta
• Zosiyanasiyana zoyikapo

Mapeto

Ma valve cheke amkuwa amakhalabe ofunikira pamakina owongolera madzimadzi, kupereka kudalirika, kukhazikika, ndi zotsika mtengo. Kumvetsetsa mitundu yawo, mapulogalamu, ndi njira zosankhidwa ndizofunikira kuti dongosolo liziyenda bwino. Pamene teknoloji ikupita patsogolo, ma valve awa amasintha, kuphatikiza zatsopano ndikusunga kufunikira kwawo kofunikira pakuwongolera madzimadzi.

Bmag imapereka mitundu yamitundu ya mavavu amkuwa kuti akhoza makonda kapena OEM / ODM kukwaniritsa zofunika zonse kasitomala. Funsani ndi gulu lathu logulitsa laukadaulo kuti mufunse.

Anthu Anafunsanso

Kodi pali kusiyana kotani pakati pa valavu yamkuwa ndi valavu yamkuwa?

Mavavu amkuwa amapangidwa kuchokera ku ma aloyi amkuwa-zinc, pamene mavavu amkuwa ali ndi ma aloyi amkuwa.
Bronze imapereka kukana bwino kwa dzimbiri koma ndiyokwera mtengo.
Brass imapereka makina abwinoko komanso okwera mtengo.

Kodi ma valve a mkuwa amatha nthawi yayitali bwanji??

Utali wamoyo weniweni: 10-15 zaka m'mikhalidwe yabwinobwino
Zinthu zomwe zimakhudza moyo wautali:
Ubwino wamadzi
Zinthu zogwirira ntchito
Machitidwe osamalira
Kuyika khalidwe

Kodi mavavu amkuwa angayikidwe molunjika?

Ma valve ambiri amkuwa amatha kukhazikitsidwa molunjika
Mitundu yodzaza masika imalimbikitsidwa kuti ikhale yoyima
Mayendedwe amayenera kukhala okwera kwa mitundu yodalira mphamvu yokoka
Onaninso zomwe wopanga amafunikira pazofunikira zinazake
