Metal Yakagara Ball Valve
Vharuvhu yesimbi yakagadzikwa bhora chii?
Vharuvhu yebhora ndeimwe yemavharuvhu anozivikanwa zvikuru mumaindasitiri akasiyana-siyana. Nekuda kweizvozvozvinhuSezvo ichidzivirira mvura zvishoma, nzira inoyerera zvakanaka, kuvhura nekuvharwa nekukurumidza, uye kudzora otomatiki kuri nyore, vharuvhu yebhora yave ichishandiswa zvakanyanya. Asi chigaro kana mavharuvhu ebhora akajairika anowanzo gadzirwa nePTFE nezvimwe zvinhu zvisiri zvesimbi. Zvichiganhurirwa nezvinhu zvechisimbiso chechigaro, mavharuvhu akajairika haagone kushandiswa mumamiriro ekushanda ekupisa kwakanyanya kana kusakara.
Saka, nhevedzano yemaitiro matsva emaitirol mavharuvhu ebhora akagadzirwa nesimbivaiveyakagadzirwa, uyeyakashandiswa zvakanyanya muindasitiri yemafuta, indasitiri yemakemikari, simba remagetsi, simbi, indasitiri yemwenje nezvimwewo
Vharuvhu yebhora yesimbi kubva kuchigaro chesimbi haina mabhenefiti akasiyana-siyana emavharuvhu ebhora eindasitiri chete, asiwo ine hunhu hwakakosha uye hwakakosha mukugara kwenguva refu kwekupisa, kunyanya kana chisimbiso chakapfava chisingakwanise kushandiswa, senge mukutumira kwepakati neguruva rakawanda, slurry, uye musanganiswa wezvinhu zvakasviba zvekunze.
Zvinhu zvikuru zvevharuvhu yebhora yakagadzikwa nesimbi?
1.Tekinoroji yeAdvanced Ball uye Seat Hardening
Kuvhara kunoitwa nesimbi pakati pebhora nechigaro chesimbi chemavharuvhu ebhora. Zvichienderana nemamiriro akasiyana ebasa uye zvinodiwa nevashandisi, matekinoroji akasiyana-siyana epamusoro ekusimbisa bhora nechigaro anogona kushandiswa, anosanganisira HVOF coating, nickel-base alloy spray welding, high nickel alloy spray welding, cobalt case hard alloy spray welding, nezvimwewo. Kazhinji kuomarara kwebhora nechigaro kunogona kusvika HRC55-60 nekukosha kwakanyanya kweHRC70. Uye kazhinji, kuramba kupisa kwechinhu chekufukidza chiso kunogona kuva 540°C, nekukosha kwakanyanya kwe980°C. Chinhu chekufukidza chiso chinewo mashandiro akanaka anodzivirira kupfeka uye anodzivirira kukuvadzwa.
2. Kuvhura nekuvhara kweVharuvhu Inochinjika
Kana tembiricha yakakwira, bhora nechigaro zvichawedzera zvakanyanya nekuda kwekuwedzera kwekupisa, uye torque ichawedzera uye vharuvhu haigone kuvhurwa, vharuvhu yebhora inoshandisa chitubu chedhisiki kana chitubu chakazadzwa nechisimbiso kuitira kuti kuwedzera kwekupisa kwezvikamu pasi pekupisa kwakanyanya kugone kunyudzwa nechisitubu chedhisiki kana chisipiti. Uye zvinova nechokwadi chekuti vharuvhu ichavhurwa nekuvharwa zviri nyore pasi pekupisa kwakanyanya pasina kuwedzera zvakanyanya.
3. Dhizaini yeChivako Chisingatsvi
Muchivakwa chevharuvhu kubva pasimbi kuenda kusimbi, gasket isimbi isina ngura + graphite inochinjika uye chiputiriso igraphite inochinjika. Saka, kuvharwa kwevharuvhu kwakavimbika kunogona kuve nechokwadi kunyangwe kana paine moto.
4. Double Block uye Bleed (Metal Seated Trunnion Ball Valve)
Vharuvhu yesimbi yakagadzikwa trunnion inowanzo gadzira chisimbiso pamberi pebhora. Kana vharuvhu yavharwa uye pakati pakabviswa vharuvhu yekuburitsa mvura, zvigaro zvepamusoro nepazasi zvinovhara mvura yega panopinda nepakubuda kuti zviite basa remabhuroko maviri.
Vharuvhu yebhora inoyangarara inogara nesimbi inowanzo tora chimiro chekuvhara mushure mebhora. Nzira yekuyerera ichaiswa chiratidzo pamuviri wevharuvhu yebhora ichivhara divi rimwe chete. Kana zvataurwa nevashandisi vekupedzisira, kuvhara divi rimwe chete kunogona kuitwa.
5. Kushanda Kwakavimbika Kwekuvhara Chisimbiso
Tekinoroji yekukuya bhora yakasiyana inoshandiswa, kuburikidza nekutenderera kwebhora uye grinder panzvimbo dzakasiyana. Bhora rinoita kuti rive rakatenderera uye rakapfava. Kuvhara chigaro chevharuvhu nechisimba kunowanikwa nekusimbiswa kwechitubu. Pamusoro pezvo, mhedzisiro yechigaro chevharuvhu yakagadzirwa zvine musoro, izvo zvinoita kuti chivharuvhu chivharuvhu nechisimba chakanyanya, kuomarara kwemavharuvhu esimbi agere pasi kunosangana nezvinodiwa zvedanho rechina re ANSI B16.104.
