Valavu ya diaphragm ndi valavu yapaderaChotsekera ndi kutseka chomwe chimagwiritsidwa ntchito ngati diaphragm yopapatiza. Vavu ya diaphragm imagwiritsa ntchito kayendedwe ka diaphragm kuti ilamulire kuyatsa ndi kutuluka kwa madzi. Ili ndi mawonekedwe osatulutsa madzi, yankho mwachangu, komanso mphamvu yochepa yogwira ntchito. Mavavu a diaphragm ndi oyenera makamaka pazochitika zomwe ziyenera kupewedwa kuipitsidwa ndi media kapena komwe kumafunika kutsegula ndi kutseka mwachangu.

2. Kugawa ndi kapangidwe ka ma valve a diaphragm

Ma valve a diaphragm akhoza kugawidwa m'magulu awa: mtundu wa ridge, mtundu wa DC, mtundu wodulidwa, mtundu wolunjika, mtundu wa weir, mtundu wa right-angle, ndi zina zotero malinga ndi kapangidwe kake; akhoza kugawidwa m'magulu awa: amanja, amagetsi, opumira mpweya, ndi zina zotero malinga ndi njira yoyendetsera. Valve ya diaphragm imapangidwa makamaka ndi thupi la valve, chivundikiro cha valve, diaphragm, mpando wa valve, tsinde la valve ndi zina.

3. Mfundo yogwirira ntchito ya valavu ya diaphragm

Mfundo yogwirira ntchito ya valavu ya diaphragm ndi iyi: Mfundo yogwirira ntchito imadalira kwambiri kayendetsedwe ka diaphragm kuti ilamulire kuyenda kwa madzi. Vavu ya diaphragm imakhala ndi diaphragm yosalala komanso chopondereza chomwe chimayendetsa diaphragm kuti isunthe. Vavu ikatsekedwa, chisindikizo chimapangidwa pakati pa diaphragm ndi thupi la valavu ndi bonnet, zomwe zimaletsa madzi kudutsa. Vavu ikatsegulidwa, mphamvu yoperekedwa ndi makina ogwiritsira ntchito imapangitsa kuti chopondereza chikwere, zomwe zimapangitsa kuti diaphragm ikwere kuchokera m'thupi la valavu ndipo madzi amayamba kuyenda. Mwa kusintha mphamvu yoperekedwa ndi makina ogwiritsira ntchito, kutsegula kwa valavu kumatha kulamulidwa, potero kuwongolera kuyenda kwa madzi.

4. Mfundo zazikulu posankha ma valvu a diaphragm

Sankhani zinthu zoyenera za diaphragm ndi zinthu za thupi la valavu malinga ndi mawonekedwe apakati.

Sankhani chitsanzo choyenera cha valavu ya diaphragm ndi zofunikira zake kutengera kuthamanga kwa ntchito.

Taganizirani momwe valavu imagwirira ntchito, kaya ndi yamanja, yamagetsi kapena yampweya.

Ganizirani za malo ogwirira ntchito ndi nthawi ya utumiki yomwe valavuyo imafunika.

5. Magawo a magwiridwe antchito a valavu ya diaphragm

Magawo akuluakulu a magwiridwe antchito a valavu ya diaphragm ndi awa: kuthamanga kwapadera, mainchesi oyambira, sing'anga yoyenerera, kutentha koyenera, njira yoyendetsera, ndi zina zotero. Magawo awa amafunika chisamaliro chapadera posankha ndikugwiritsa ntchito mavalavu a diaphragm.

6. Zochitika zogwiritsira ntchito ma valavu a diaphragm

Ma valve a diaphragm amagwiritsidwa ntchito kwambiri m'mafakitale azakudya, mankhwala, kuteteza chilengedwe, mankhwala ndi mafakitale ena, makamaka m'malo omwe ndikofunikira kupewa kuipitsidwa kwa media ndikutsegula ndi kutseka mwachangu, monga kukonza zimbudzi, kukonza chakudya, ndi zina zotero.

7. Kukhazikitsa valavu ya diaphragm

1. Kukonzekera musanayike

Onetsetsani kuti chitsanzo ndi zofunikira za valavu ya diaphragm zikugwirizana ndi zofunikira pa kapangidwe kake.

Yang'anani mawonekedwe a valavu ya diaphragm kuti muwonetsetse kuti palibe kuwonongeka kapena dzimbiri.

Konzani zida ndi zipangizo zofunikira zoyikira.

2. Kufotokozera mwatsatanetsatane njira zokhazikitsira

Malinga ndi kapangidwe ka payipi, dziwani malo oyika ndi komwe valavu ya diaphragm ikupita.

Ikani valavu ya diaphragm pa chitoliro, kuonetsetsa kuti thupi la valavulo likufanana ndi pamwamba pa chitoliro ndipo likulowa bwino.

Gwiritsani ntchito mabolts kuti mumangirire thupi la valavu ku flange ya chitoliro kuti muwonetsetse kuti kulumikizana kuli kotetezeka.

Yang'anani momwe valavu ya diaphragm imatsegukira komanso momwe imatsekera kuti muwonetsetse kuti diaphragm ikhoza kuyenda momasuka komanso kuti palibe kutuluka kwa madzi.

3. Malangizo okhazikitsa

Pewani kuwononga diaphragm panthawi yoyika.

Onetsetsani kuti njira yoyendetsera ya diaphragm valve ikugwirizana ndi njira yogwirira ntchito.

Onetsetsani kuti valavu ya diaphragm yayikidwa mbali yoyenera kuti isasokoneze ntchito yake yanthawi zonse.

4. Mavuto ndi mayankho ofala a kukhazikitsa

Vuto: Valavu ya diaphragm imatuluka pambuyo poyiyika. Yankho: Onani ngati cholumikiziracho chili cholimba, ndikuchilimbitsanso ngati chamasuka; onani ngati diaphragm yawonongeka, ndikuyiyikanso ngati ili yofooka.

Vuto: Valavu ya diaphragm si yosinthasintha potsegula ndi kutseka. Yankho: Yang'anani ngati makina ogwiritsira ntchito ndi osinthasintha, ndipo ayeretseni ngati pali kutsekeka kulikonse; yang'anani ngati diaphragm ndi yolimba kwambiri, ndipo isintheni ngati ndi yolimba.

5. Kuyang'anira ndi kuyesa pambuyo pokhazikitsa

Yang'anani mawonekedwe a valavu ya diaphragm kuti muwonetsetse kuti palibe kuwonongeka kapena kutayikira.

Gwiritsani ntchito valavu ya diaphragm ndipo yang'anani momwe imatsegukira ndi kutsekera kuti muwonetsetse kuti ndi yosinthasintha komanso yopanda chopinga.

Yesani kulimba kuti muwonetsetse kuti valavu ya diaphragm siituluka madzi ikakhala yotsekedwa.

Kudzera mu njira ndi njira zodzitetezera zomwe zili pamwambapa, mutha kuwonetsetsa kuti valavu ya diaphragm yayikidwa bwino komanso kuti igwire ntchito bwino kuti ikwaniritse zofunikira pakugwiritsa ntchito.
