DIN3202 Cast Steel Gate Valve
Vavu yachipata imatanthawuza valavu yomwe gawo lake lotsekera (chipata) limayenda motsatira njira yolowera pakati pa tchanelo.Vavu yachipata imagwiritsidwa ntchito makamaka podula mapaipi.Valve yopangidwa ndi zitsulo zachitsulo ndi valve yogwiritsidwa ntchito kwambiri.Nthawi zambiri amagwiritsidwa ntchito podula zida zokhala ndi DN ≥ 50mm, ndipo nthawi zina valavu yachipata imagwiritsidwanso ntchito podula zida zokhala ndi mainchesi ochepa.Valve yachipata, monga valve yotsika, imakhala yofala kwambiri.
Zofunika za valve Gate:
Kuchita bwino kusindikiza, kukana kwamadzimadzi pang'ono ndi machitidwe ena amalamulo;Komabe, ili ndi kukula kwakukulu, kapangidwe kake kovutirapo, kukonza kovuta, kuvala kosavuta kwa kusindikiza pamwamba, kukonza zovuta komanso nthawi yayitali yotsegula ndi kutseka.Ndikoyenera kupanga ma valve akuluakulu a diameter.Kuphatikiza pa nthunzi, mafuta ndi zofalitsa zina, ndizoyeneranso zofalitsa zomwe zimakhala ndi zolimba za granular ndi viscosity yapamwamba, komanso ma valve opangira mpweya komanso otsika.
