Muindasitiri yekudzora mvura yemvura,butterfly valveskuita basa rakakosha mukudzora, kutungamira, uye kupatsanura kuyerera kwezvinwiwa, magasi, uye slurries mumapaipi. A flanged butterfly valve imhando imwe yemhando yekubatanidza, ine mafingerwo akabatanidzwa pamativi ese emuviri wevharuvhu, ichibvumira kusungirirwa kwakachengeteka mabhaudhi kune pombi flanges.
The quarter-turn rotation mechanism ye aflanged butterfly valveinoisiyanisa kubva kumutsara mavharuvhu senge gedhi kana globe mavharuvhu, achipa mabhenefiti mukumhanya uye kugona kwenzvimbo.
Ichi chinyorwa chichaongorora zvakadzama zveflanged butterfly mavharuvhu, kufukidza dhizaini yavo, mhando, zvinhu, maapplication, zvakanakira uye zvakaipira, kuisirwa, kugadzirisa, kuenzanisa nemamwe mavharuvhu, uye mafambiro emangwana.
1. Tsanangudzo uye Nheyo Yekushanda
A flanged butterfly valve is a 90-degree rotational motion valve inoratidzwa nedhisiki inodzora kuyerera kwemvura kuburikidza nedzinde kutenderera. Muviri wevharuvhu unoratidza maflange pamigumo yese yekubatanidza mabhaudhi akananga kune pombi. Flange butterfly mavharuvhu anoratidza akasimudzwa kana kuti flat flanges ane maburi maburi, achipa kubatana kwakasimba uye kwakagadzikana kwakakodzera kune yakaderera, yepakati, uye yakakwirira-kudzvanywa application, pamwe nediki, yepakati, uye yakakura madhayamita.
Nheyo yekushanda iri nyore uye inoshanda. Ivhavha ine muviri wevharuvhu, dhisiki yevharuvhu, dzinde revharuvhu, chigaro chevharuvhu, uye actuator. Kana mubato kana giya rinoshandiswa, kana tsinde yevhavha inotenderedzwa neatomatiki actuator, dhisiki yevhavha inotenderera ichibva panzvimbo yakatarisana negwara rekuyerera (yakazara yakazaruka) kune perpendicular chinzvimbo (yakavharwa zvizere). Munzvimbo yakavhurika, dhisiki yevharuvhu inowirirana nepipeline axis, kuderedza kuyerera kwekudzivirira uye kurasikirwa kwekumanikidza. Kana yakavharwa, dhisiki yevhavha inovhara pachigaro mukati memuviri wevhavha.
Iyi nzira inobvumira kukurumidza kushanda kwevharuvhu, kazhinji ichingoda kutenderera kwe90-degree chete, ichiita kuti ikurumidze kupfuura mavharuvhu akawanda. Flanged butterfly mavharuvhu anokwanisa kubata bidirectional kuyerera uye anowanzo akashongedzerwa nezvigaro zvesimbi kana simbi kuti ive nechokwadi chekuvharika kwakasimba. Dhizaini yavo inovaita kuti vanyanyokodzera masisitimu anoda kuchinjika nguva nenguva kana kuti nzvimbo ishoma.
2. Zvikamu
Zvikamu zvikuru zvinosanganisira:
- Muviri wevhavha: Imba yekunze, kazhinji kaviri-flange kuvakwa, inopa zvimiro zvekubatanidza uye dzimba dzemukati zvikamu. Simbi yekabhoni inoshandiswa kushandiswa zvakajairika, simbi isina simbi yekudzivirira ngura, nickel-aluminum bhuronzi yenzvimbo dzemugungwa, uye alloy simbi yemamiriro akanyanya.
- Disiki revhavha:Chinhu chinotenderera, chinowanikwa mune yakakwenenzverwa kana kuti flat dhizaini, inodzora kuyerera. Iyo disc inogona kuiswa pakati kana kumisa kuti iwedzere kuita. Simbi isina simbi, aruminiyamu yebhuronzi, kana yakavharwa nenaironi kuitira kunatsiridza kusakara.
- Dzinde: Shaft inobatanidza diski yevharuvhu kune actuator inotumira simba rekutenderera. Simbi isina simbi kana yakakwirira-simba alloys inomira torque.
Kuburikidza ne-shaft kana maviri-chidimbu madzinde anowanzoshandiswa, akashongedzerwa zvisimbiso kudzivirira kubuda.
- Seat: Iyo yekuisa chisimbiso inogadzirwa neye elastomeric zvinhu senge EPDM kana PTFE. EPDM (-20°F kusvika ku250°F), BUNA-N (0°F kusvika ku200°F), Viton (-10°F kusvika ku400°F), kana PTFE (-100°F kusvika ku450°F) inoshandiswa kune zvisimbiso zvinyoro; zvinhu zvesimbi senge simbi isina tsvina kana Inconel zvinoshandiswa kune yakakwirira-tembiricha yakaoma zvisimbiso.
-Actuator: Inoshandiswa nemaoko (mubato, giya) kana powered (pneumatic, magetsi).
- Kurongedza uye gaskets: Ita shuwa yekuvuza-yakasimba zvisimbiso pakati pezvikamu uye pane flange zvinongedzo.
Izvi zvikamu zvinoshanda pamwechete kuti zvipe yakavimbika kuyerera kutonga.
3. Mhando dzeFlanged Butterfly Valves
Flanged butterfly mavharuvhu anogona kukamurwa sezvinotevera zvichienderana ne disc alignment, actuation method, uye body type.
3.1 Kururamisa
- Concentric (zero offset): Dzinde revharuvhu rinopfuura nepakati pedhisiki uye rinoratidza chigaro chinotsiga. Iri vharuvhu rakakodzera kune yakaderera-pressure application ine tembiricha inosvika 250°F.
-Kubvisa kaviri: Iyo tsinde yevharuvhu inogadziriswa kuseri kwe disc uye kure-pakati, kuderedza chigaro kupfeka. Iyi vharafu inokodzera zvepakati-kudzvanywa maapplication uye tembiricha inosvika 400°F.
- Katatu offset: Iyo yakawedzera tapered chigaro kona inogadzira simbi-kune-simbi chisimbiso. Iri vharafu rakakodzera kune yakakwirira-kumanikidza (kusvika kuKirasi 600) uye yakakwirira-tembiricha (kusvika 1200).°F) zvikumbiro uye zvinosangana ne zero-leakage zvinodiwa.
3.2 Actuation Nzira
Mhando dzeActuation dzinosanganisira manyorero, pneumatic, magetsi, uye hydraulic kugarisa akasiyana ekushanda zvinodiwa.
4. Indasitiri Applications
Flanged butterfly mavharuvhu anoshandiswa zvakanyanya muzvikamu zvinotevera:
-Kugadziriswa kweMvura neMvura: Inoshandiswa kudzora kuyerera muzvidyarwa zvekurapa uye diversion masisitimu. -Kemikari Kugadziriswa: Kubata maasidhi, alkalis, uye zvinonyungudutsa zvinoda corrosion-resistant zvinhu.
-Oiri & Gasi: Piping yemafuta asina kuchena, gasi rechisikigo, uye maitiro ekunatsa.

8. Kuenzanisa nemamwe mavharuvhu
Kuenzaniswa nemavharuvhu egedhi, mavharuvhu e butterfly ane flanged anoshanda nekukurumidza uye anopa throttling kugona, asi ari kushomeka kushomeka kuyerera.
Kuenzaniswa nemavharuvhu ebhora, iwo ane mari yakawanda kune madhayamita akakura, asi anoona kurasikirwa kwakanyanya kwekumanikidzwa panguva yekuvhurwa.
Globe mavharuvhu anopa zvirinani kunyatsoita throttling, asi akakura uye anodhura.
Pakazere, mavharuvhu eshavishavi anokunda munzvimbo-inomanikidzirwa uye isingadhuri maapplication.
