Momwe mungayikitsire valavu ya phazi lamadzi?

Choyamba, cholinga cha valavu ya Phazi:

Phazi valavu ndi valavu yopulumutsa mphamvu.Nthawi zambiri imayikidwa kumapeto kwa Phazi la chitoliro chokokera pansi pamadzi cha mpope wamadzi.Imalepheretsa kubwereranso kwa madzi mupaipi yapampopi yamadzi ku gwero la madzi, ndipo imasewera ntchito yolowa komanso osalowa.Pali zinthu zambiri zolowera m'madzi ndi nthiti zolimbitsa pachivundikiro cha valve.Ndizovuta kutsekereza, komanso zomwe zimagwiritsidwa ntchito popopera mapaipi, maukonde amadzi amathandizanso.Ubwinowu uli ndi lobe imodzi, lobe iwiri, komanso mitundu yamitundu yambiri.Pali maulalo a flange ndi maulalo a ulusi.
Valve ya Phazi imapangidwa ndi thupi la valve, disc valve, chivundikiro cha valve, bushing, mphete yosindikizira ndi mbali zina.Onani chithunzi pansipa kuti mudziwe zambiri.madzi ochokera m'madzi amapita ku valavu ya phazi kuchokera pachivundikiro cha phazi.Kuthamanga kwa chitoliro chakumbuyo kumatseka chitoliro cha valve, ndipo madziwo sadzatsanuliridwa ku gwero lamadzi, lomwe limagwira ntchito yopopera bwino ndikupulumutsa mphamvu yamadzi.

Chachiwiri, malangizo oyika ma valve a Phazi:

3. 1. Pofuna kupewa kubwereranso kwa sing'anga, ma valve a cheke ayenera kuikidwa pa zipangizo, zipangizo ndi mapaipi.
2. Valavu yoyang'ana nthawi zambiri ndi yoyenera kwa sing'anga yoyera, osati yoyenera sing'anga yomwe ili ndi tinthu tating'onoting'ono komanso kukhuthala kwakukulu;
3. Nthawi zambiri, ma valve okwera okwera ayenera kugwiritsidwa ntchito pamapaipi opingasa okhala ndi mainchesi 50 mm.

Kuyika chidwi ndi kukonza

1. Onetsetsani kuti thupi la vavu layikidwa molunjika Pansi pa mpope woyamwa madzi,
2. Chitoliro choyamwa chikadzadza ndi madzi, chimayamba nthawi yomweyo, zomwe zimapangitsa kuti paipi yoyamwa ikhale yopanda phokoso, ndipo madzi amalowetsedwa mupaipi yowongoka kuti amalize kupopera.

kukonzanso

1. Kuti muwonjezere moyo wautumiki wa valavu yapansi, samalani kuti muwone maonekedwe a valavu ndikuchitapo kanthu panthawi yake.
2. Valve yapansi imapezeka kapena popanda kasupe.Ma valve ambiri a njira imodzi ali ndi kasupe, koma kasupe nthawi zambiri amakhala ofewa ndipo kukana koyenda kumatha kunyalanyazidwa.Nthawi zambiri ma valve a njira imodzi yokhala ndi zitseko zotsegula pamwamba pa 0.3 MPa adzadziwika ndi akasupe pa hydraulic schematic.
3. Makulidwe azinthu zopangidwa ndi HONGKE VALVE amachokera ku 3/4 inch-8 inch.Chonde onetsani nambala yachitsanzo pogula.
