一、 Nhanganyaya:
Yakavigwa yakapfava-yakavharwa gedhi vharafu ivharuvhu yegedhi yakakosha inogona kuvigwa zvakananga muvhu kudzora kuyerera kwemapaipi akavigwa. Chinhu chikuru cheiyo yakananga-yakavigwa yakapfava-chisimbiso gedhi vharafu ndeyekuti yekumusoro uye yakaderera inofamba gedhi inoshanda sevhavha kuvhura uye kuvhara chikamu. Hunde yevharuvhu yevharuvhu yakavigwa yakapfava-chisimbiso yegedhi yakarebesa uye inogona kugadzirwa zvinoenderana nenzvimbo dzakasiyana dzekushandisa dzine hurefu hwakasiyana hwemadzinde evharuvhu, iyo inogona kusangana nezvinodiwa zvekushandisa zvakasiyana-siyana zvekuvaka pombi yekanzuru. Iyo yakavigwa yakapfava-chisimbiso gedhi vharafu inovigwa pasi pepamusoro kwenguva yakareba, nzvimbo yekushanda ine hutsinye, uye haigone kutsiva uye kugadzirisa, saka kunaka kwevhavha kunonyanya kutariswa pakusarudza yakavigwa yakapfava-chisimbiso gedhi valve.
二、Zvinhu:
1. Kuiswa kwakavigwa kunogona kuitwa, izvo zvinogona kuchengetedza mari yekuchera matsime makuru-diameter uye kugadzirisa shaft wall. Nzvimbo yakazaruka yepasi idiki uye haizokanganisa kunaka kwemugwagwa. Inochengetedza mari uye inobvisa kuchengetedzwa kunokonzerwa nekurasikirwa kwedambudziko rekuvharisa tsime.
2. Matanda evhavha ehurefu hwakasiyana anogona kugadzirwa maererano nekushandiswa chaiko. Chiratidzo chekuvhura nekuvhara gedhi rakagadzirirwa pamusoro pevhavha stem, iyo inoshanduka uye iri nyore kushanda.
3. Iyo yakanaka yakavanzwa tsvimbo yakagadzirwa ine compact chimiro uye inonzwisisika kugovera. Chigaro chevharuvhu chakagadzirwa nechepasi pasi. Iyo valve haisi nyore kuunganidza tsvina uye inotora chisimbiso chakapfava. Dzinde revharuvhu rakashongedzerwa neakawanda “o”-akaita seavhare mhete. Kuita kwemhepo kunopinza kwakanaka chaizvo uye kuyerera kwemvura kunotsvedzerera.
4. Pamusoro pemuviri wevhavha yose inogadziriswa ne epoxy resin uye inogadziriswa nehexagonal bolts. Iyo vharuvhu ine yakasarudzika anti-corrosion kugona uye yakasimba uye yakasimba.
5. Zvikamu zvemukati zvose zvakapfapfaidzwa ne-non-toxic epoxy resin, iyo yakachengeteka uye isina chepfu. Iyo yemukati nharaunda inosangana neakakodzera hutsanana zviyero uye inogona kushandiswa mumapombi emvura pombi.
