ASME Globe Valve
Chii chinonzi ASME Globe Valve?
Mavharuvhu eGlobe mavharuvhu anovhara anofamba nemutsara anoshandiswa kutanga, kumisa kana kudzora kuyerera kwemvura achishandisa chinhu chinovhara chinonzi dhisiki. Chigaro chevharuvhu yepasi chiri pakati uye chakafanana nepaipi, uye gomba riri pachigaro rinovharwa nedhisiki kana plug. Dhisiki yevharuvhu yepasi inogona kuvhara nzira yekuyerera kwemvura zvachose kana kubviswa zvachose. Kuvhura kwechigaro kunochinja zvinoenderana nekufamba kwedhisiki iyo yakakodzera mabasa ane chekuita nekudzora kuyerera kwemvura. Mavharuvhu eGlobe anonyanya kukodzera uye anoshandiswa zvakanyanya kudzora kana kumisa kuyerera kwemvura kana gasi kuburikidza nepaipi yekudzora nekudzora kuyerera kwemvura uye anowanzo shandiswa mumapaipi madiki.
ASME Globe vharuvhundeimwe yemagadzirirwo akakurumbira emavharuvhu epasi rose, eUS neAPI system. Dhayamita yemukati, zvinhu, chiso nechiso, ukobvu hwemadziro, tembiricha yekumanikidzwa, zvinotsanangurwa neASME B16.34.
Pamusoro pezvo, zvichienderana nekugadzirwa kwechigaro nedhisiki, mutoro wezvigaromavharuvhu epasi rose eASMEinogona kudzorwa zvakanaka nesimbi yakasungirirwa. Kugona kwekuvhara kwevharuvhu yepasi rose yeASMEyakanyanya kukwira. Inogona kushandiswa pabasa rekushanda. Nekuda kwedaro diki rekufamba kwediski pakati penzvimbo dzakavhurika nedzakavharwa,mavharuvhu epasi rose eASMEZvakanakira kana vharuvhu ichifanira kuvhurwa nekuvharwa nguva nenguva. Saka, mavharuvhu epasi anogona kushandiswa pamabasa akasiyana-siyana.
iyoMavharuvhu eASME Globeinogona kushandiswawo pakugadzirisa tambo. Mavharuvhu mazhinji anogara munhu mumwe chete anoshandisa keji kana dhizaini yekuchengeta kuti achengetedze chigaro, ape gwara remavharuvhu, uye ape nzira yekusimbisa hunhu hwemavharuvhu chaiwo. Inogonawo kuchinjwa nyore nyore nekuchinja zvikamu zve trim kuti ichinje hunhu hwemavharuvhu kana kupa mukana wakaderera.kuyerera, kuderedza ruzha, kana kuderedza kana kubvisa cavitation.
Mapatani emuviri eASME Globe Valve, kune mapatani matatu makuru emuviri kana magadzirirwo emavharuvhu eGlobe, anoti:
- 1).Standard Pattern (inozivikanwawo seTee Pattern kana T - Pattern kana Z - Pattern)
- 2). Muenzaniso weAngle
- 3). Patani yeOblique (inozivikanwawo seWye Patani kana Y - Patani)
Nheyo yekushanda yeASME Globe Valve
Vharuvhu yepasi rose ine dhisiki inofambiswa uye chigaro cherin'i chisingachinjiki mumuviri wakaita sedenderedzwa. Chigaro chevharuvhu yepasi rose chiri pakati uye chakafanana nepombi, uye gomba riri pachigaro rinovharwa nedhisiki. Kana vhiri reruoko rikatenderedzwa nemaoko kana neactuator, kufamba kwedhisiki kunodzorwa (kudzikiswa kana kusimudzwa) kuburikidza nesimbi yevharuvhu. Kana dhisiki yevharuvhu yepasi rose yakagara pamusoro perin'i rechigaro, kuyerera kwayo kunomira zvachose.
Chinhu chikuru chevharuvhu yeASME Globe
- 1) .Good chisimbiso kugona
- 2). Kufamba kwenguva pfupi kwediski (stroke) pakati penzvimbo dzakavhurika nedzakavharwa,mavharuvhu epasi rose eASMEzvakanaka kana vharuvhu ichifanira kuvhurwa nekuvharwa nguva nenguva;
- 3).Vharuvhu yeASME globe inogona kushandiswa sevharuvhu yekumisa nekuchinja dhizaini zvishoma.
- 4).THeino mhando dzakasiyana dzezvishandiso zvinowanikwa mumhando dzeT-shirt, Wye, uye angle body.
- 5).Kugadzira nekugadziridza zvigaro zviri nyore, nekuda kwezvinangwa zvakasiyana-siyana.
- 6).Kugona kupinza makumbo zvakanaka kusvika pakati nepakati, nekushandura chimiro chechigaro nedhisiki.
- 7).BChisimbiso che ellows chinowanikwa kana uchikumbira.

- 2). Mvura: Mvura, utsi, mhepo, peturu isina kuchena uye zvigadzirwa zvepeturu, gasi rechisikigo, gasi remhepo, mhinduro dzehunyanzvi, okisijeni, magasi emvura uye asina hukasha
- 3).Masisitimu emvura anotonhodza anoda kudzorwa kwekuyerera kwemvura.
- 4).Sisitimu yemafuta emafuta inoda kusimba kwekudonhedza mvura.
- 5).Masisitimu ekudzora mavharuvhu.
- 6).Maburi emvura ane nzvimbo dzakakwirira uye madhireni ane nzvimbo dzakaderera.
- 7).Oiri neGasi, Mvura yekudya, chikafu chemakemikari, Refinery, kuburitsa mhepo inotonhorera, uye masisitimu ekuburitsa mvura inoyerera.
- 8).Maburi emhepo nedhiraivha, masevhisi emhepo nedhiraivha, maburi makuru emhepo nedhiraivha, uye maburi emvura nedhiraivha.
