Kana vatengi vanotenga katatu eccentric butterfly mavharuvhu, vanowanzoreva kune maviri marudzi ezvivakwa, imwe isimbi kune chigaro chesimbi uye imwe yacho ine-multi-layer type;vane zvimiro zvakasiyana uye mitengo yacho yakatosiyanawo.Tevere, ngatikurukurei musiyano uripo pakati pese-simbi chigaro butterfly mavharuvhu uye akawanda-layer sealing butterfly mavharuvhu.
1. Hunhu hwesimbi kune simbi chigaro butterfly mavharuvhu
Simbi kune simbi chigaro butterfly mavharuvhu ari shavishavi vharafu ane nyore chisimbiso chimiro, rinoumbwa vharafu muviri, vharafu ndiro, vharafu shaft uye yose simbi chisimbiso mhete.Iyo ine compact dhizaini uye inochinjika kuvhura nekuvhara, saka inoshandiswa zvakanyanya mumamiriro ezvinhu ane yakaderera kudzvinyirira, kuyerera kudiki, tembiricha yakakwira uye diki guruva.
Mushure mokunge ndiro yevhavha yakavhurwa, chigaro chevhavha chemuviri wevhavha chiri pedyo nemhete yekuisa chisimbiso.Kana ndiro yevharuvhu yakavharwa yakananga kumvura, zvimedu zvepakati mumvura zvakakura zvakanyanya kana zvakanyanya kuoma, izvo zvinokonzeresa friction pachigaro chevharuvhu kana mhete yekuisa chisimbiso, zvichikonzera Kukuvadza kuchigaro chevhavha kana mhete yekuisa chisimbiso inodzivirira kuvharwa kwakazara.Ichi zvakare chimwe chezvikanganiso zvesimbi kune simbi chigaro butterfly vharafu, nekuti kazhinji kuchinjika kuchaita kuti kuwedzere kukweshana uye nokudaro kukanganisa hupenyu hwebasa.
2. Hunhu hweakawanda-layer katatu eccentric butterfly valve
Multi-layer butterfly vharuvhu ivharuvhu yeshavishavi ine yakaoma chisimbiso chimiro.Mhete yekuisa chisimbiso inowanzoumbwa nezvikamu zviviri kana kupfuura, nepakati pekuisa chisimbiso akawanda.Muviri wevharuvhu neplate yevharuvhu ye-multi-layer butterfly valve zvakaunganidzwa muzvikamu.Nheyo imwe neimwe ine yakazvimiririra yekuisa chisimbiso chimiro, iyo inogona kunyatso kudzikisa njodzi yekudonha.Nokuti iri chisimbiso che-multi-layer chisimbiso, kunyange kana pane zvimedu mukati mepakati panguva yekuvhara, chero bedzi ma-interlayers ose asina kukuvadzwa, kunyange kana chidimbu chimwe chete chikasara chisina kuparadzwa, kushanda kwekuvhara hakuzokanganisi.
Iwo mavharuvhu evhavhavha anowanzo shandiswa munzvimbo dzakanyanya-kudzvanya uye nekuyerera kwakakura, senge oiri isina kukora, gasi rechisikigo, mvura uye mamwe mapaipi emaindasitiri.Kushanda tembiricha iri pakati -29 madhigirii uye 425 madhigirii.WCB zvinhu ndiyo inodhura-inoshanda sarudzo.
3. Musiyano pakati pesimbi kune simbi butterfly mavharuvhu uye akawanda-layer butterfly mavharuvhu
1) kufanana kweaya maviri butterfly vales
Zvosesimbi kune simbi butterfly valveuye multi-layer butterfly valve inogona kuwana imwe-nzira yekuisa chisimbiso kana maviri-nzira yekuisa chisimbiso kuita.Zvinoenderana nezvido zvevashandisi, seti imwe kana anopfuura ezvindori zvekuvharisa zvinogona kutsiviwa kuti zvive nyore kutsiviwa kana zvikasashandiswa zvakanaka, uye zvakagadzirirwa kuve zvinofambiswa nzira mbiri dzekuisa chisimbiso.Chakanakira dhizaini iyi ndechekuti chigaro chevharuvhu uye mhete yekuisa chisimbiso inogona kutsiviwa online, uye midziyo haidi kuve isina kuvharwa pakugadzirisa.Panguva imwecheteyo, ivo vese vane mukana wekuwedzera uye kusimba.
2) misiyano pakati pemavhavha maviri aya
Musiyano mukuru uri muchimiro uye mamiriro ekushandisa.
① musiyano wechimiro
Multi-layer butterfly valve
· Chimiro che-multi-layer butterfly valve is stack yesimbi mapepa uye graphite, izvo zvinoreva kuti mhete yekuisa chisimbiso inowanzoumbwa nezvikamu zviviri kana kupfuura, nepakati pekuisa chisimbiso.Muviri wevharuvhu neplate yevharuvhu yevakawanda-layer butterfly valve yakaunganidzwa muzvikamu, uye yega yega ine yakazvimirira yekuisa chisimbiso chimiro.
· Iyo yekuisa chisimbiso chevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha yesimbi,kureva kuti,inoisa chisimbiso uye chigaro chevharuvhu, inogadzirwa nesimbi yese.Mhete yekuisa chisimbiso inogona kunge yakatarisana kana kupfapfaidza yakasungwa neakasiyana-siyana asingapfeke uye anodzivirira tembiricha alloys.

② Kushandisa
Iyo Metal kune simbi butterfly valve yakakodzera kune yakaderera kudzvinyirira, kuyerera kudiki, uye yakakwirira tembiricha mamiriro;iyo yakawanda-layer butterfly valve ine yakazara yakazara-yakawanda-layer chisimbiso chimiro, icho chinogona kunyatso kudzikisa njodzi yekudonha.
4. Simbi kune simbi yekuisa chisimbiso kushanda kweshavishavi mavharuvhu uye akawanda-layer butterfly mavharuvhu
Zvinoenderana neyakajairwa API598, vharuvhu yeshavishavi ine simbi yakaoma kubata inogona kuve nekudonha chiyero, asi shavishavi ine mhete dzekuvharisa akawanda-layer inogona kuita 0 sealing uye ine yepamusoro seal performance.
5. Zvishandiso zvesimbi-sealing sealing butterfly mavharuvhu uye akawanda-layer sealing butterfly mavharuvhu
·Chisimbiso chesimbi chakazara: Chigaro chevhavha kazhinji chine Stellite, zvinhu zvemuviri ndeyeWCB, SS304, SS316, SS2205, SS2507, uye mhete yevhavha yevhavha yekuvhara inogona kusarudzwa maererano nezvinhu zveplate yevhavha;
·Multi-layer sealing ring: Valve seat material: Stellite, kana body material, valve plate yekuvhara mhete inowanzoshandisa RPTFE/PTFE + metal, graphite + metal;
Kazhinji, ose musoro-pamashavishavi mavharuvhu uye multi-pamwero shavishavi mavharuvhu vane yavo inoshanda mamiriro, uye vanoshandisa vanogona kusarudza zvakakodzera shavishavi vharafu mhando maererano chaiwo mamiriro.Paunosarudza vhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha,zviyero zvakadai semvura inoyerera, tembiricha, kuyerera kweyero uye svikiro zvinofanira kutariswa kuitira kuti usarudze rudzi rwakakodzera rwevharuvhu yeshavivhavha uye ive nechokwadi chekushanda kwevhavha.
Kana tembiricha yakanyanya kukwirira uye pasina zvidimbu zvakakura, unogona kusarudza simbi yakaoma-yakavharwa butterfly valve.
Kana tembiricha isina kunyanya kukwira uye yepakati iine zvidimbu, sarudza yakaderera-yemutengo yakawanda-layer sealing butterfly valve.
