Kune marudzi mazhinji emavharuvhu eshavishavi, uye kune nzira dzakawanda dzekuisa.
1. Kurongwa nechimiro chechimiro
(1)concentric butterfly valve; (2) single-eccentric butterfly valve; (3) kaviri-eccentric butterfly valve; (4) matatu-eccentric butterfly valve
2. Classification maererano nechisimbiso pamusoro zvinhu
(1) Resilient butterfly valve
(2) Metal-mhando yakaoma-yakavharwa butterfly valve. Iyo yekuisa chisimbiso inoumbwa nesimbi yakaoma zvinhu kune simbi yakaoma zvinhu.
3. Kurongwa nefomu rakavharwa
(1) Kumanikidzwa kuvharwa shavishavi vharuvhu.
(2) Kumanikidza kuvhara shavishavi vharafu. Iyo yekusimbisa chisimbiso inogadzirwa neiyo elastic sealing element pachigaro kana ndiro.
(3) Automatic sealed butterfly valve. Iyo chisimbiso chaiyo pressure inogadzirwa otomatiki nepakati pressure.
4. Kurongeka nedzvinyiriro yebasa
(1) Vacuum butterfly valve. Butterfly valve ine simba rekushanda rakaderera pane mhepo yakadzika.
(2) Low-pressure butterfly valve. Butterfly vharuvhu ine zita rekumanikidza rePN≤1.6MPa.
(3) Medium-pressure butterfly valve. Iro zita rekuti PN ivharuvhu yeshavishavi ye2.5∽6.4MPa.
(4) High-pressure butterfly valve. Iyo inonzi nominal pressure PN ivharuvhu yeshavishavi ye10.0∽80.OMpa.
(5) Ultra-high pressure butterfly valve. Butterfly valve ine zita rekumanikidza PN <100MPa.
5. Kurongwa nekubatanidza mode
(1)Wafer butterfly valve
(2) Flange butterfly valve
(3) Lug butterfly valve
(4) Welded butterfly valve
Concentric Butterfly valve imhando yevharuvhu inovhura nekuvharika nedenderedzwa yeshavishavi ndiro yovhura, inovhara nekugadzirisa gwara remvura nekutenderera kwedzinde revharuvhu. Iyo butterfly plate ye butterfly valve inoiswa mudhayamita kutungamira kwepombi. Mune cylindrical channel ye butterfly valve body, disc butterfly plate inotenderera yakapoteredza axis, uye kutenderera Angle iri pakati pe 0 ne 90. Kana kutenderera kunosvika 90, valve yakazaruka zvakakwana.
Zvinhu zvakakosha zvekuvaka uye kuisa
1) Nzvimbo yekuisa, kureba, kuendesa kunze uye kutungamira kunze kwenyika kunofanirwa kusangana nezvinodiwa zvekugadzira, uye kubatana kunofanirwa kuve kwakasimba uye kwakasimba.
2) Mubato wemarudzi ese emavharuvhu akaiswa papombi yekupisa yekupisa haifanirwe kudzika.
3) Ivhavha inofanira kuongororwa kunze kusati yaiswa, uye zita rezita revhavha richasangana nezvinodiwa zvemazuva ano enyika "General Valve Mark" GB 12220. Kune mavharuvhu ane kushanda kwekushanda kukuru kupfuura 1.0 MPa uye kucheka pane chikuru. pombi, simba uye bvunzo dzakasimba dzekuita dzichaitwa isati yaiswa uye ichashandiswa mushure mekukwanisa. Muyedzo yesimba, kudzvanywa kweyedzo ndeye 1.5 nguva dzezita rekumanikidza, uye nguva yacho haisi pasi pe5min. Iyo goko revhavha uye kurongedza kunofanirwa kuve kwakakodzera pasina kuvuza. Kune iyo tightness bvunzo, kudzvanywa kwebvunzo ndeye 1.1 nguva dzezita rekumanikidza; iyo bvunzo yekumanikidza ichasangana neiyo GB 50243 yakajairwa yenguva yekuyedzwa, uye iyo valve seal surface inokodzera.
Kusarudzwa kwechigadzirwa chezvibodzwa zvakakosha
1. Iyo mikuru yekudzora ma paramita evhavhavhavhavha ndeyekutsanangurwa uye zviyero.
2. Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhava,varo nyore kugadzirwa,yakanakira kushandiswa,yakaderera mari,kureruka kushanda, asi kururamisa kururamisa kwakaipa, chete akakodzera ventilation uye air conditioning system nokuda chinja kana coarse kugadziridzwa chiitiko.
3. Inogona kunge iri manual, magetsi kana zipper type operation, inogona kugadziriswa pane chero Angle ye90 range.
4. Pamusana peaxial single valve plate, simba rekutakura rinogumira, mumamiriro ekudzvinyirira kukuru, kuyerera kukuru kana hupenyu hwebasa revhavha hupfupi. Iyo valve ine yakavharwa mhando uye yakajairika mhando, insulation uye isiri-insulation.
5. Ivhavhavhavhavhavhavha yegetsi ine mhando mbiri chete, electric actuator yakafanana nevhavhavha yemashizha akawanda.
