Zofunikira pazakuthupi ndi Zaukadaulo za valavu Yoyendetsa magetsi pamagetsi apamagetsi (1)
Choyamba, ponena za kusankha valavu, m'masiku oyambirira a kukhazikitsidwa kwa Special Zone, maukonde a chitoliro chamadzi anali osakwana makilomita 10, ndipo ambiri mwa maukonde a chitoliro ankagwiritsa ntchito ma valve a pakhomo. Chifukwa cha maukonde osavuta a chitoliro komanso kumangika bwino kwa ma valve a pachipata, ntchito ya ma valve mu network ya chitoliro sinali yofunika kwambiri. Vavu yagulugufe yofewa. Malo osindikizira nthawi zambiri amapangidwa ndi mphira wa butadiene ndi rabara ya epDM, ndi zina zotero. Zinthu zosindikizira ziyenera kukwaniritsa zofunikira zazizindikiro zaumoyo, ndikuwonetsa mayeso oletsa kukalamba ndi kuyesa kukana kukana;
Choyamba, ponena za kusankha valavu, m'masiku oyambirira a kukhazikitsidwa kwa Special Zone, maukonde a chitoliro chamadzi anali osakwana makilomita 10, ndipo ambiri mwa maukonde a chitoliro ankagwiritsa ntchito ma valve a pakhomo. Chifukwa cha maukonde osavuta a chitoliro komanso kumangika bwino kwa ma valve a pachipata, ntchito ya ma valve mu network ya chitoliro sinali yofunika kwambiri. Ndipo kumayambiriro kwa zaka za m'ma 1990, kugwiritsa ntchito valavu ya butterfly m'dziko lonselo mwamphamvu, panthawiyo, kupanga valavu yagulugufe ku China kunangoyamba kumene, mphamvu zoponyera mu thupi sizili zazikulu, ntchito ya valve mbale ya apuloni yosindikizira ndi yosauka, ubwino wa mavuto a butterfly valve ndi wochuluka. ndi zoonekeratu zoonekeratu. Ma valve omwe amagwiritsidwa ntchito pa netiweki ya chitoliro amagawidwa ndi caliber: valavu yachipata imagwiritsidwa ntchito pamene DN≤400mm, valve butterfly imagwiritsidwa ntchito pamene DN400mm. Maziko waukulu wa gulu ndi kuti 90% ya yokonza kasamalidwe ntchito mu maukonde chitoliro amapezeka ang'onoang'ono-caliber chitoliro maukonde pansipa DN400mm, kotero pamafunika kumangika bwino kutsegula ndi kutseka mavavu mu maukonde chitoliro. Ndipo chifukwa caliber ndi yaying'ono, mphamvu ya ntchito ya kutsegula ndi kutseka kwa valve si yaikulu. Komabe, pafupipafupi chitoliro anaphulika mu DN400mm chitoliro maukonde ndi m'munsi kwambiri kuposa ang'onoang'ono-caliber chitoliro maukonde, ndi ntchito mphamvu ya kutsegula ndi kutseka pambuyo ntchito gulugufe valavu ndi utachepa.
