Mawonekedwe a valavu ya mpira

Valavu yoyang'ana mpira imatchedwanso valavu yoyang'anira zimbudzi za mpira.Thupi la valve limapangidwa ndi chitsulo cha nodular cast.Utoto wamtundu wa valavu umapangidwa ndi utoto wopanda poizoni wa epoxy pambuyo pophika kutentha kwambiri.Pamwamba pa penti ndi yosalala, yosalala komanso yowala mumtundu.Mpira wokutira wachitsulo wophimbidwa ndi mphira umagwiritsidwa ntchito ngati diski ya valve.Pansi pa zochita za sing'anga, imatha kugudubuza mmwamba ndi pansi pa slideway mu thupi la valve kuti mutsegule kapena kutseka valve.Ili ndi ntchito yabwino yosindikiza, kutseka kwachete, ndipo palibe nyundo yamadzi.Njira yoyendetsera madzi ya thupi la valve imakhala ndi kukana pang'ono, kutuluka kwakukulu, ndi 50% kutayika kwa mutu pang'ono kusiyana ndi mtundu wa screw-up.Ikhoza kukhazikitsidwa molunjika komanso molunjika.Ntchito yake ndikuletsa sing'anga mu payipi kuti isabwererenso.

Thupi la valavu la valavu yoyang'ana madzi ozungulira amadzimadzi amatengera dongosolo lonse, lomwe lili ndi ubwino wa kutuluka kwakukulu ndi kutsika kochepa.Vavu chimbale ndi mpira wozungulira, oyenera mkulu-makamaka mamasukidwe akayendedwe, inaimitsidwa zolimba mafakitale ndi zoweta zimbudzi chitoliro maukonde.Ndi valavu yapadera yoyang'anira zimbudzi, zonyansa zamafakitale, ndi mapaipi amadzi am'nyumba.Ndizoyenera kwambiri pamapampu amadzi amadzimadzi a submersible.

Malingana ndi kugwirizana kosiyanasiyana,valavu ya mpiraimagawidwa kukhalavalavu yoyang'ana mpira wa flangedndivalavu yoyang'ana mpira.

1. Main luso magawo

Kupanikizika mwadzina PN1.0MPa ~ 1.6MPa, Kalasi125/150;

M'mimba mwake mwadzina DN40 ~ 400mm, BSP/BSPT 1″~3″;

Ntchito kutentha 0 ~ 80 ℃

2. Mapangidwe ake

1. Kutalika kwake ndi kwaufupi, ndipo kutalika kwake ndi 1/4 ~ 1/8 yokha ya valavu yachikhalidwe ya flange.

2. Kukula kwakung'ono, kulemera kopepuka, ndi kulemera kwake ndi 1/4 ~ 1/20 yokha ya valavu yotsekera yotseka pang'onopang'ono

3. Chovala cha valve chimatseka mwamsanga ndipo kuthamanga kwa nyundo yamadzi kumakhala kochepa

4. Mapaipi onse opingasa ndi ofukula angagwiritsidwe ntchito, osavuta kukhazikitsa

5. Njira yothamanga imakhala yosasunthika ndipo kukana kwamadzimadzi kumakhala kochepa

6. Kuchita mwachidwi ndi ntchito yabwino yosindikiza

7. Chiwopsezo cha disc ndi chachifupi, ndipo kutseka kwa valve kumakhala kochepa

8. Mapangidwe onse, ophweka ndi osakanikirana, maonekedwe okongola

9. Moyo wautali wautumiki ndi kudalirika kwakukulu
