1. Chii chinonzi vharuvhu yegedhi?
Vharuvhu yegedhi ivharuvhu inoshandiswa KUVHURURA NEKUDZIMA kuyerera kwemvura iri mupaipi. Inovhura kana kuvhara vharuvhu nekusimudza gedhi kuti ibvumire kana kudzora kuyerera kwemvura. Zvinofanira kusimbiswa kuti vharuvhu yegedhi haigone kushandiswa kudzora kuyerera kwemvura, asi yakakodzera chete kumashandisirwo anoda kuyerera kwemvura zvizere kana kuvharwa kwemvura zvakakwana.

2. Chimiro cheVharuvhu yeGedhi
Mavharuvhu egedhi anowanzo kuve nezvinhu zvakakosha zvakati wandei:
1) Muviri wevharuvhu: Chinhu chinonyanya kukosha chevharuvhu yegedhi. Chinhu chacho chinowanzogadzirwa nesimbi ine ductile, WCB, SS, nezvimwewo.
2) Gedhi: chiyuniti chekudzora, chinogona kunge chiri ndiro yakaputirwa nerabha kana ndiro yesimbi yakachena.
3) Hunde yevharuvhu: inoshandiswa kusimudza gedhi, yakagadzirwa neF6A (yakagadzirwa ss 420), Inconel600.
4)Bhoneti: goko riri pamusoro pemuviri wevharuvhu, iro pamwe chete nemuviri wevharuvhu zvinoumba goko revharuvhu regedhi rakakwana.
5) Chigaro chevharuvhu: nzvimbo yekuvhara apo ndiro yegedhi inobatana nemuviri wevharuvhu.
3. Ndeapi Mhando dzakasiyana dzeMavharuvhu eGate?
Zvichienderana nerudzi rwechimiro chemudzi wevharuvhu, inogona kukamurwa kuita vharuvhu yegedhi remudzi risingakwiri uye vharuvhu yegedhi remudzi risingakwiri.
1)Vharuvhu yegedhi remudzi isingakwiri:Pamusoro pehunde yevharuvhu yevharuvhu yegedhi rakavanzika haritambanuke nevhiri reruoko. Purati yegedhi inokwira kana kudzika ichitevedza hunde yevharuvhu kuti ivhure kana kuvhara vharuvhu yegedhi. Purati yevharuvhu yevharuvhu yese yegedhi ndiyo chete ine kufamba kwekutama.
2)Vharuvhu yegedhi rinokwira (vharuvhu yegedhi reOS&Y):Pamusoro pegumbo revharuvhu rinokwira rinoonekwa pamusoro pevhiri reruoko. Kana vharuvhu revharuvhu ravhurwa kana kuvharwa, gumbo revharuvhu neplate yegedhi zvinosimudzwa kana kudzikiswa pamwe chete.
4. Vharuvhu yeGedhi Inoshanda Sei?
Kushanda kwevharuvhu yegedhi kuri nyore uye kunosanganisira matanho anotevera:
1) Kuvhurika: Kana vharuvhu yegedhi yavhurika, ndiro yegedhi inosimudzwa zvachose uye mvura inogona kuyerera zvakanaka kuburikidza negwara remuviri wevharuvhu.
2) Mamiriro ekuvharwa: Kana vharuvhu ichifanira kuvharwa, gedhi rinodzikiswa pasi. Rinodzvanywa pachigaro chevharuvhu uye richibata pamusoro pechisimbiso chemuviri wevharuvhu, zvichidzivirira kupfuura kwemvura.
5. Vharuvhu yeGedhi Inoshandiswa Sei?
Mavharuvhu egedhi ane mashandisirwo akasiyana-siyana uye anogona kushandiswa mumaindasitiri akasiyana-siyana nenzvimbo, senge:
1) Kurapa nemvura: Mavharuvhu egedhi rekuisa chisimbiso chakapfava anonyanya kushandiswa pakurapa mvura netsvina.
2) Indasitiri yemafuta negasi rechisikigo: Mavharuvhu egedhi rekusimbisa zvakasimba anoshandiswa muindasitiri yemafuta negasi rechisikigo.
3) Kugadziriswa kwemakemikari: Mavharuvhu egedhi resimbi isina ngura akakodzera kudzora kuyerera kwemakemikari nezvinwiwa zvinoparadza mukugadzirwa kwemakemikari.
4) Masisitimu eHVAC: Mavharuvhu egedhi anoshandiswa mumasisitimu ekudziyisa, kufefetedza uye ekutonhodza mhepo (HVAC).
Saka, mavharuvhu egedhi anogona kushandiswa pakudhonza here?
Sezvatinoona kubva pane zviri pamusoro apa, mhinduro ndeyekuti KWE! Chinangwa chekutanga chevharuvhu yegedhi ndechekuvhurwa zvizere uye kuvharwa zvizere. Kana ikashandiswa zvine simba kugadzirisa kuyerera kwemvura, kuyerera kusina kunaka, kutenderera nezvimwe zvinhu zvichaitika, uye zvinokonzeresa nyore nyore kutsemuka kweropa nekupfekwa.
6. Mabhenefiti eGedhi Valve
1) Kuyerera kwakazara: Kana yavhurwa zvizere, gedhi rinoenzana nepamusoro pepombi, zvichiita kuti kuyerera kurege kuvharwa uye kuderedzwa kushoma kwekumanikidzwa.
2)0 Kubuda Kwemvura: Kana gate plate yakabatana nechigaro chevharuvhu, chisimbiso chakasimba chinogadzirwa kudzivirira mvura kuti isabude nepavharuvhu. Nzvimbo dzekuvhara dzechigaro chegedhi nevharuvhu dzinowanzogadzirwa nezvinhu zvakaita sesimbi kana elastomer kuti mvura ivharwe uye mhepo ivharwe pasina kubuda.
3) Kuvhara mavharuvhu egedhi: Mavharuvhu egedhi anogona kupa kuvharwa kwemativi maviri, zvichiita kuti akwanise kushandiswa mumapaipi ane kuyerera kunodzoreka.
4) Kugadzirisa kuri nyore: Hapana chikonzero chekuputsa vharuvhu yegedhi zvachose. Unongofanira kuvhura chifukidziro chevharuvhu kuti unyatsoona chimiro chemukati kuti chigadziriswe.
7. Zvakaipa zveMavharuvhu eGedhi
1) Kana tichienzanisa nemamwe mavharuvhu ane maumbirwo akareruka (akadai semavharuvhu eshavishavi), muviri wevharuvhu unoshandisa zvinhu zvakawanda uye mutengo wacho wakakwira.
2) Dhayamita yepamusoro yevharuvhu yegedhi inofanira kunge iri diki, kazhinji DN≤1600. Vharuvhu yeshavishavi inogona kusvika DN3000.
3) Vharuvhu yegedhi inotora nguva yakareba kuvhurwa nekuvharwa. Kana ichida kuvhurwa nekukurumidza, inogona kushandiswa ne pneumatic actuator.
