Chii chinonzi globe valve?
Vharuvhu yeguruvaYakagadzirwa uye inogadzirwa zvichienderana neyaimbova Germany standard, DIN uye mazuva ano European standard EN13709.inonyanya kushandiswa munyika dziri muEuropean Union.
Ivharuvhu yayo yekuvhara inofamba nemutsara inoshandiswa kutanga, kumisa kana kudzora kuyerera kwemvura uchishandisa chinhu chinovhara chinonzi dhisiki. Kuvhurika kwechigaro kunochinja zvinoenderana nekufamba kwedhisiki iyo yakakodzera mabasa ane chekuita nekudzora kuyerera kwemvura. Mavharuvhu eDIN-EN Globe anonyanya kukodzera uye anoshandiswa zvakanyanya kudzora kana kumisa kuyerera kwemvura kana gasi kuburikidza nepombi yekudzora nekudzora kuyerera kwemvura uye anowanzo shandiswa mumapaipi madiki.
iyoMavharuvhu epasiinogona kushandiswawo pakubatsira kupinza tambo. Mavharuvhu mazhinji anogara munhu mumwe chete anoshandisa keji kana dhizaini yekuchengeta kuti achengetedze chigaro, ape gwara remavharuvhu, uye anopa nzira yekusimbisa hunhu hwemavharuvhu chaiwo. Inogonawo kuchinjwa nyore nyore nekuchinja zvikamu zve trim kuti ichinje hunhu hwemavharuvhu kana kupa kuyerera kwakaderera, kuderedza ruzha, kana kuderedza kana kubvisa cavitation.
kazhinji pane mapatani matatu makuru emuviri kana magadzirirwo eMavharuvhu epasi:
- 1).Standard Pattern (zvakare seTee Pattern kana T - Pattern kana Z - Pattern)
- 2). Muenzaniso weAngle
- 3). Patani yeOblique (inozivikanwawo seWye Patani kana Y - Patani)
Zvinhu zvikuru zvevharuvhu yepasi rose?
Maitiro akajairwa (maitiro akatwasuka)
Maitiro ekona
Patani yakajairika ine chisimbiso chebellows
- 1). Kufamba kwenguva pfupi kwediski (stroke) pakati penzvimbo dzakavhurika nedzakavharwa,Mavharuvhu epasi peDIN-ENzvakanaka kana vharuvhu ichifanira kuvhurwa nekuvharwa nguva nenguva;
- 2) .Good chisimbiso kugona
- 3). Kune mhando dzakasiyana dzehunyanzvi dziripo mu standard pattern (streight pattern), Angle pattern, uye Wye pattern (Y pattern).
- 4). Vharuvhu yeDIN-EN inogona kushandiswa sevharuvhu yeSDNR, vharuvhu yekutarisa pasi rose nekuchinja dhizaini zvishoma.
- 5). Kugadzira nekugadziridza zvigaro zviri nyore, nekuda kwezvinangwa zvakasiyana-siyana.
Kugadzirisa dhizaini yemadhisiki
