Chii chinonzi Throttling 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.
Vharuvhu yepasi rose inofambisa mvura ndeimwe 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 wezvigaroVharuvhu yepasi rose inofambisa mvurainogona kudzorwa zvakanaka nesimbi yakasungirirwa. Kugona kwekuvhara kweVharuvhu yepasi rose inofambisa mvurayakanyanya kukwira. Inogona kushandiswa pabasa rekushanda. Nekuda kwedaro diki rekufamba kwediski pakati penzvimbo dzakavhurika nedzakavharwa,Vharuvhu yepasi rose inofambisa mvuraZvakanakira kana vharuvhu ichifanira kuvhurwa nekuvharwa nguva nenguva. Saka, mavharuvhu epasi anogona kushandiswa pamabasa akasiyana-siyana.
iyoVharuvhu yepasi rose inofambisa mvurainogona 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.

Kushandiswa kweThrottling globe valve
ASME Globe Valveinoshandiswa zvakanyanya mumabasa akasiyana-siyana; ese ari maviri, ane pressure shoma uye ane pressure yakakwira. Mashandisirwo akajairika ema globe valves ndeaya:
- 1). Yakagadzirirwa pombi inowanzo shandiswa, kana kupwanya mvura nepakati pegasi.
- 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.
