Nhanganyaya kuBhora mavharuvhu
Mavharuvhu ebhora
Vhuru yeBhora ivharuvhu yekota-turn rotational motion valve inoshandisa dhisiki rakaita sebhora kumira kana kutanga kuyerera. Kana vharuvhu yakavhurwa, bhora rinotenderera kusvika pane imwe nzvimbo iyo buri kuburikidza nebhora rinoenderana nevharuvhu body inlet nekubuda. Kana vharuvhu yakavharwa, bhora rinotenderedzwa kuitira kuti gomba rive perpendicular kune kuyerera kwekuvhura kwemuviri wevhavha uye kuyerera kunomiswa.
Mhando dzeBhora mavharuvhu
Mavharuvhu ebhora anowanikwa mune matatu mavhezheni: yakazara port, venturi port uye yakaderedzwa chiteshi. Iyo yakazara-port valve ine dhayamita yemukati yakaenzana nedhayamita yemukati yepombi. Venturi uye yakaderedzwa-chiteshi shanduro kazhinji idiki pombi saizi idiki pane saizi yemutsetse.
Mavharuvhu ebhora anogadzirwa mune akasiyana masisitimu emuviri uye anonyanya kuzivikanwa ndeaya:
- Pamusoro pekupinda Mavharuvhu ebhora anobvumira kupinda kune mavharuvhu emukati kuti agadzirise nekubviswa kwevharuvhu Bonnet-kavha. Izvo hazvidiwi kubviswa valve kubva kune pombi system.
- Split body Bhora mavharuvhu ane zvikamu zviviri, apo chimwe chikamu chidiki sechimwe. Bhora rinopinzwa muchikamu chikuru chemuviri, uye chikamu chidiki chemuviri chinounganidzwa nekubatanidza mabhaudhi.
Ivhavha inopera inowanikwa sebutt welding, socket welding, flanged, threaded nezvimwe.
Zvishandiso – Dhizaini – Bonet
Zvishandiso
Mabhora anowanzo kugadzirwa nesimbi akati wandei, nepo zvigaro zvichibva kune zvakapfava seTeflon®, Neoprene, uye musanganiswa wezvinhu izvi. Kushandiswa kwezvinhu zvakapfava-seat zvinopa kugona kwakanakisa kuvhara. Iko kusakanganiswa kwezvinhu zvakapfava-seat (elastomeric zvinhu) ndezvekuti, izvo hazvisi zvinogona kushandiswa mukupisa kwakanyanya maitiro.
Semuyenzaniso, zvigaro zvefluorinated polymer zvinogona kushandiswa kudziya tembiricha kubva −200° (uye yakakura) kusvika 230°C zvichikwira, nepo zvigaro zvegraphite zvichigona kushandiswa kutonhora kubva pa?° kusvika pa500°C zvichikwira.
Stem design
Dzinde riri muBhora vharuvhu harina kubatanidzwa nebhora. Kazhinji ine rectangular chikamu pabhora, uye iyo inokwana mune yakachekwa yakachekwa mubhora. Kuwedzerwa kunobvumira kutenderera kwebhora sezvo vharuvhu inovhurwa kana kuvharwa.
Bhora vharafu Bhoneti
Bhoneti yeBhora vharuvhu inosungirira kumuviri, iyo inobata stem musangano uye bhora panzvimbo. Kugadziriswa kweBonnet kunobvumira kudzvanywa kwekutakura, iyo inopa chisimbiso che stem. Kurongedza zvinhu zveBall valve stems kazhinji Teflon® kana Teflon-yakazadzwa kana O-mhete pane kurongedza.
Ball mavharuvhu zvikumbiro
Aya anotevera mamwe akajairika mashandisirwo eBhora mavharuvhu:
- Mhepo, gasi, uye kushandiswa kwemvura
- Madhiraini uye anobuda mumvura, gasi, uye mamwe masevhisi emvura
- Steam service
Zvakanakira uye Zvakaipa zveBhora mavharuvhu
Zvakanakira:
- Quick quarter turn on-off operation
- Kusunga chisimbiso ne torque yakaderera
- Diki muhukuru kupfuura mamwe mavharuvhu mazhinji
Zvakaipa:
- Mavharuvhu akajairwa Bhora ane hurombo hwekukwenya zvivakwa
- Mune slurry kana mamwe maapplication, zvimedu zvakamiswa zvinogona kugara uye kuvharirwa mumakomba emuviri zvichikonzera kupera, kuvuza, kana kutadza kwevharuvhu.
