Mavharuvhu ebhoraane zvimiro zvakawanda, asi zvakangofanana.Nzvimbo dzekuvhura nekuvhara dzakatenderedza spherical cores, dzinonyanya kuumbwa nezvigaro zvevharuvhu, mabhora, mhete dzekuisa chisimbiso, madzinde evharuvhu uye zvimwe Zvishandiso zvekushandisa.Hunde yevharuvhu inotenderera 90 madhigirii kuti iwane kuvhurwa nekuvhara kwemavharuvhu.Mavharuvhu ebhora anoshandiswa pamapaipi kuvhara, kugovera, kudzora kuyerera uye kushandura mafambiro epakati.Chigaro chevharuvhu chinoshandisa mafomu ekuisa chisimbiso akasiyana zvichienderana nemamiriro ekushanda akasiyana.Muviri weO-type bhora vharafu une bhora rine pakati nepakati neburi iro dhayamita rakaenzana nedhayamita repombi.Bhora rinogona kutenderera muchigaro chekuisa chisimbiso.Kune annular elastic mhete pamativi ese ari maviri munzira yepombi.V-mhando yebhora valve ine V-yakaita chimiro.Mukati wevharuvhu i 1/4 spherical shell ine V-yakaita notch.Iyo ine yakakura kuyerera simba, yakakura inogadziriswa siyana, kugera simba, uye inogona kuvharika zvakasimba.Inonyanya kukodzera kumvura mamiriro ezvinhu apo zvinhu zvine fibrous.
1. O-mhando bhora vharafu chimiro:
Iyo O-type bhora vharafu inodzora nzira yepakati ne y kutenderedza bhora 90 °, semhedzisiro, iyo kuburikidza negomba inogona kuchinjwa, nekudaro kuona kuvhurwa nekuvhara kwevhavha yebhora.Iyo O-mhando yebhora vharafu inotora inoyangarara kana yakagadziriswa dhizaini.Idzo nhengo dzinofamba dzakagadzirwa nezvinhu zvekuzvizora zvine diki friction coefficient, saka torque inoshanda idiki.Mukuwedzera, kuvharwa kwenguva refu kwegirisi yekuisa chisimbiso kunoita kuti kushanda kuwedzere kushanduka.Zvibereko zvayo zvechigadzirwa ndezvizvi:
-
O-mhando bhora vharafu ine diki mvura inodzivirira
Mavharuvhu ebhora kazhinji ane zvimiro zviviri: dhayamita rakazara uye dhayamita rakaderedzwa.Hazvina mhosva kuti ndechipi chimiro, kuyerera kupikisa coefficient yevhavha yebhora ishoma.Mavharuvhu ebhora akajairika akatwasuka, anozivikanwawo semavharuvhu ebhora akazara.Iyo dhayamita yechiteshi yakaenzana nepakati dhayamita yepombi, uye kurasikirwa kwekupokana ndiko chete kupesana kwekupokana kwehurefu hwakafanana hwepombi.Iri vharuvhu yebhora rine kushomeka kwemvura kunopesana nemavharuvhu ese.Kune nzira mbiri dzekudzikisa kushorwa kwepombi system: imwe ndeyekudzikisa kuyerera kwemvura nekuwedzera dhayamita yepombi uye dhayamita yevharuvhu, izvo zvichawedzera zvakanyanya mutengo wepombi system.Chechipiri ndechekuderedza kushorwa kwenzvimbo yevhavha, uye mavharuvhu ebhora ndiyo yakanakisa sarudzo.

Iyo O-type bhora vharafu inochinja nekukurumidza uye zviri nyore
Ivhavha yebhora inongoda kutenderera 90 degrees kuti ivhure zvizere kana kunyatsovhara, saka inogona kuvhurwa nekuvharwa nekukurumidza.
- O-type bhora vharafu ine yakanaka yekuisa chisimbiso kuita
Zvizhinji zvezvigaro zvevharuvhu zvebhora zvinogadzirwa nemidziyo yakanyunguduka sePTFE, iyo inowanzonzi mavharuvhu akapfava-sealing ball.Soft sealing bhora mavharuvhu ane yakanaka yekuisa chisimbiso uye haidi yakakwira roughness uye kugadzirisa iko kurongeka kwevhavha yekuvharisa pamusoro.
-
O-mhando yebhora vharafu ine hupenyu hurefu hwebasa
Nekuti PTFE/F4 ine yakanaka yekuzvizora zvivakwa, iyo friction coefficient ine sphere idiki.Pamusana pekuvandudzwa kwekugadzirisa teknolojia, kuoma kwebhora kunoderedzwa, nokudaro kuwedzera zvikuru hupenyu hwebasa revhavha yebhora.
-
O-mhando bhora vharafu ine yakakwirira kuvimbika
Iyo yekuisa chisimbiso chebhora uye chigaro chevhavha haizotambudziki nekukwenya, kukurumidza kupfeka uye zvimwe zvikanganiso;
Mushure mokunge tsinde yevhavha ichishandurwa kune yakavakirwa-mukati mhando, njodzi yengozi iyo tsinde yevhavha inogona kubhururuka kunze nekuda kwekusunungurwa kwegland yekutakura pasi pechiito chekumanikidzwa kwemvura kunobviswa;
Mavharuvhu ebhora ane anti-static uye asingadziviri moto zvimiro anogona kushandiswa mumapaipi anotakura oiri, gasi rechisikigo, uye gasi remarasha.
Mwoyo wevharuvhu (bhora) weO-type bhora vharafu ine denderedzwa.Kubva pakuona kwemaitiro, chigaro chebhora chinosungirirwa pachigaro padivi remuviri wevhavha kana uchivhara.Idzo nhengo dzinofamba dzakagadzirwa nezvinhu zvekuzvizora zvine diki friction coefficient, saka torque inoshanda idiki.Mukuwedzera, kuvharwa kwenguva refu kwegirisi yekuisa chisimbiso kunoita kuti kushanda kuwedzere kushanduka.Kazhinji inoshandiswa pakugadzirisa-nzvimbo mbiri, maitiro ekuyerera anokurumidza kuvhura.
Kana O-type bhora vharuvhu yakazaruka zvizere, mativi ose haana kuvharika, achigadzira gwara rakatwasuka rine nzira mbiri.Iyo ine yakanakisa "kuzvichenesa" kuita uye inokodzera maviri-nzvimbo yekucheka nguva dzeakanyanya kuchena uye ine fiber-ine media.Iyo bhora core inogara ichigadzira friction nevhavha panguva yekuvhura nekuvhara maitiro evhavha.Panguva imwecheteyo, chisimbiso pakati pepakati pevhavha uye chigaro chevhavha chinowanikwa ne-pre-tightening sealing simba rechigaro chevharuvhu chinotsikirira pamusoro pebhora repakati.Nekudaro, nekuda kwechigaro chakapfava chekuisa chisimbiso chevharuvhu, Yakanakisa michina uye yemuviri zvimiro inoita yekuisa chisimbiso kuita kwayo kunyanya kunaka.
2.V-yakaita bhora vharafu chimiro:
Iro bhora remukati weV-shaped ball valve ine V-shaped structure.Mukati wevharuvhu i 1/4 spherical shell ine V-yakaita notch.Iyo ine yakakura kuyerera simba, yakakura inogadziriswa siyana, kugera simba, uye inogona kuvharika zvakasimba.Inonyanya kukodzera zvinwiwa.Mamiriro ezvinhu apo zvinhu zvine fibrous.Kazhinji, V-shaped bhora mavharuvhu mavharuvhu ebhora-seal.Haikodzeri kushandiswa kwenzira mbiri.
Kune kunyanya 4 mhando yeV-yakaita notch, 15 degree, 30 degree, 60 degree, 90 degree.
Mupendero wakaita V unocheka tsvina.Panguva yekutenderera kwebhora, V-yakaita banga rakapinza mupendero webhora inotenderera kune chigaro chevharuvhu, nokudaro ichicheka fiber uye zvinhu zvakasimba mumvura.Nekudaro, mavharuvhu akajairwa ebhora haana basa iri, saka zviri nyore kuita kuti fiber tsvina ibatike kana ichivhara, zvichikonzera kugadzirisa uye kugadzirisa matambudziko.Maintenance kukanganisa kukuru.Iyo yevhavha yepakati yeV-yakaita bhora vharafu haizobatiki nefibers.Mukuwedzera, nekuda kwekubatana kweflange, zviri nyore kuparadzanisa uye kuunganidza pasina maturusi anokosha, uye kugadzirisa zvakare kuri nyore.kana vharuvhu yakavharwa.Pane chigero chakaita wedge-chakaita chigero pakati peV-shaped notch uye chigaro chevharuvhu, iyo isingaite yekuzvichenesa chete asiwo inodzivirira bhora repakati kubva kunamira.Muviri wevharuvhu, chivharo chevhavha uye chigaro chevharuvhu chinotora simbi inonongedza-ku-point zvimiro zvakateerana, uye diki friction coefficient inoshandiswa.Iyo tsinde yevharuvhu yakatakurwa-yakatakura, saka torque yekushandisa idiki uye yakagadzikana kwazvo.
Iyo V-yakaita bhora vharafu ndeyekurudyi-ekona inotenderera dhizaini inogona kuwana kuyerera kwemutemo.Inogona kuwana madhigirii akasiyana echiyero zvichienderana neV-yakaita angle yeV-yakaita bhora.Iyo V-yakaita bhora vharafu inowanzo shandiswa pamwe chete nemavharuvhu actuators uye mapositioners kuti awane kuenzana kugadziridzwa., V-shaped valve core ndiyo inonyanya kukodzera zviitiko zvakasiyana-siyana zvekugadzirisa.Iyo ine yakakura yakayerwa kuyerera kweyeyero, yakakura inogadziriswa reshiyo, yakanaka yekuisa chisimbiso mhedzisiro, zero senitivity mukugadzirisa mashandiro, saizi diki, uye inogona kuiswa yakatwasuka kana yakatwasuka.Inokodzera kudzora gasi, chiutsi, mvura uye mamwe midhiya.Iyo V-shaped ball valve ndiyo yakarurama-angle rotary structure, iyo inoumbwa neV-shaped valve body, pneumatic actuator, positioner nezvimwe zvinhu;ine inherent flow character yeinenge yakaenzana reshiyo;inotora chimiro chine mbiri, ine diki yekutanga torque, uye ine yakanakisa Sensitivity uye yekunzwa kumhanya, kugona kukuru kwekuveura.
