CHV103-125
Chifukwa chiyani kuwonjezera silinda iyi?
Ndi silinda yakunja, pamene diski ya valve imatseka mwamsanga koma ikadali 30% yotsala kuti itseke, silinda imayamba kugwira ntchito, kuchititsa kuti mbale ya valve itseke pang'onopang'ono. Izi zingalepheretse sing'anga mupaipi kuti isachuluke msanga kuthamanga ndikuwononga dongosolo la mapaipi
Chifukwa chiyani kuwonjezera kulemera kwa block?
Yokhala ndi chipika cholemetsa, imatha kutseka payipi mwachangu ndikuchotsa nyundo yamadzi yowononga
MSS SP-71 Class 125 Cast Iron Air Cushion Swing Check Valve ndi valavu yachitsulo yachitsulo yomwe imagwirizananso ndi American Standard Manufacturing Society (MSS) SP-71 ndipo idavotera Class 125. Zotsatirazi ndi mawonekedwe, Ubwino ndi kugwiritsa ntchito valavu iyi:
Chepetsani nyundo yamadzi: Mapangidwe a khushoni ya mpweya amatha kuchepetsa nyundo yamadzi ndi kugwedezeka, kuwongolera kukhazikika ndi chitetezo cha mapaipi.
Kudalirika kwanthawi yayitali: Zida zachitsulo zotayira zimakhala ndi kukana kwa dzimbiri, kuonetsetsa kudalirika kwa valavu pakugwiritsa ntchito nthawi yayitali.
Kugwira ntchito mwachisawawa: Malingana ndi kayendedwe kapakati, valavu imatha kutsegula kapena kutseka popanda kugwiritsa ntchito pamanja.
Kagwiritsidwe:MSS SP-71 Kalasi ya 125 Cast Iron Air Cushion Swing Check Valve imagwiritsidwa ntchito makamaka pamapaipi a mafakitale, makamaka m'malo omwe mawayilesi amasinthasintha kwambiri, zomwe zimayambitsa nyundo yamadzi ndi kugwedezeka mosavuta. Malo omwe amagwiritsidwa ntchito kawirikawiri amaphatikizapo njira zoperekera madzi, njira zoyeretsera zimbudzi, kupanga mafakitale ndi njira za mankhwala. Valavu yamtunduwu imatha kuteteza bwino dongosolo la mapaipi, kuwonetsetsa kukhazikika kwa media, kuchepetsa kupsinjika ndi kutayika kwa mapaipi, ndikuwongolera chitetezo ndi kudalirika kwadongosolo.
Mapangidwe a mpweya: Ali ndi mapangidwe apadera a mpweya omwe amagwiritsa ntchito matumba a mpweya kapena zipinda zosungiramo mpweya kuti apereke kayendedwe ka valve yosalala komanso kuchepetsa nyundo ya madzi ndi kugwedezeka.
Wopangidwa ndi chitsulo chosungunula: Thupi la valve ndi chophimba cha valve nthawi zambiri chimapangidwa ndi chitsulo choponyedwa, chomwe chimakhala ndi mphamvu yokana dzimbiri komanso mphamvu.
Chivundikiro cha valavu ya Swing: Mapangidwe a swing amatsimikizira njira yoyenera yoyendetsera ndikuteteza bwino kubweza kwapakati.
