Professional kugadzirwa ASME BS1873 kukandira simbi gorobhu mavharuvhu kumisa vharafu China fekitari mutengesi
Chii chinonzi BS1873 globe valve?
BS1873 vharuvhu yepasi
ndeimwe yeanonyanya kufarirwa magadzirirwo eglobe mavharuvhu, eUS uye API system.the mukati dhayamita, zvinhu, chiso nechiso, kukora kwemadziro, tembiricha yekumanikidza, zvinotsanangurwa neASME B16.34.
theBS1873 vharuvhu yepasiinogona kushandiswa throttling zvinangwa uyewo.Many single-akagara mavharuvhu miviri anoshandisa keji kana retainer-style kuvaka kuchengetedza chigaro-mhete, kupa vharafu plug guiding, uye kupa nzira yokugadza mamwe vharafu kuyerera maitiro.inogonawo kuchinjwa nyore nyore nekushandurwa kwezvikamu zvekucheka kushandura maitiro ekuyerera kana kupa kuderedzwa-kukwanisakuyerera, ruzha attenuation, kana kuderedza kana kubviswa cavitation.
ASME Globe Valve Body Pateni, kune matatu ekutanga emuviri mapatani kana magadzirirwo eGlobe mavharuvhu, anoti:
- 1).Standard Pattern (inozivikanwawo seTee Pattern kana T - Pattern kana Z - Pattern)
- 2).Angle Pattern
- 3).Oblique Pattern (inozivikanwawo seWye Pattern kana Y - Pattern)
Kushanda Nheyo yeBS1873 vharuvhu yepasi
Ivhavhavhavha inoumbwa nedhisiki rinofambiswa uye chigaro chemhete chakamira mumuviri wakatenderera.Chigaro chevhavha yepasi chiri pakati uye chakafanana nepombi, uye kuvhura pachigaro kunovharwa ne disc.apo handwheel inotenderedzwa nemaoko kana neactuator, kufamba kwe disc kunodzorwa (kuderedzwa kana kusimudzwa) nenzira yevhavha stem.Kana iyo globe valve disc inogara pamusoro pechigaro chechigaro, kuyerera kunomira zvachose.
Chinhu chikuru cheBS1873 globe valve
- 1).Kugona kuisa chisimbiso kwakanaka
- .ASME globe mavharuvhuzvakanaka kana vharuvhu ichifanirwa kuvhurwa uye kuvharwa kazhinji;
- 3).Iyo ASME globe valve inogona kushandiswa sevhavha yekumira-cheki nekugadzirisa dhizaini zvishoma.
- 4).Theino huwandu hwakasiyana hwekugona sekuwanikwa mune tee, Wye, uye angle body masitaera.
