Iyo kaviri eccentric butterfly valve inotumidzwa zita rezvimiro zvaro zviviri eccentric.Saka iyo double eccentric structure yakaita sei?
Iyo inonzi double eccentric, yekutanga eccentric inoreva shaft yevharuvhu iri kubva pakati penzvimbo yakavharwa, zvinoreva kuti dzinde riri kuseri kwechiso chevharuvhu.Eccentricity iyi inoita kuti pakatarisana neplate yevharuvhu uye chigaro chevharuvhu chive chisimbiso, icho chinokunda kusakwana kwemukati kunowanikwa mumavharuvhu e butterfly, zvichibvisa mukana wekupinda mukati mukati mekumusoro nezasi mharadzano pakati pevharuvha shaft uye. chigaro chevharuvhu.
Imwe eccentricity inoreva nzvimbo yevharuvhu yemuviri uye tsinde axis kuruboshwe uye kurudyi kurerutsa, kureva kuti, dzinde rinopatsanura ndiro yeshavishavi muzvikamu zviviri, chimwezve uye chimwe zvishoma.Iyi eccentricity inogona kuita kuti butterfly plate mukuvhura nekuvhara nzira ikurumidze kuvharwa kana pedyo nechigaro chevharuvhu, kuderedza kupokana pakati peplate yevharuvhu uye chigaro chevharuvhu chakavharwa, kuderedza kupera uye kubvaruka, kuderedza kuvhura nekuvhara torque, uye kuwedzera hupenyu hwebasa rechigaro chevhavha.
Mavharuvhu Aviri Eccentric Butterfly Anovhara Sei?
Denderedzwa rekunze replate yevharuvhu uye chigaro chakavharwa cheviri eccentric butterfly valve inogadzirwa kuita hemispherical surface, uye yekunze spherical pamusoro peplate yevharuvhu inosvina yemukati spherical pamusoro pechigaro chakavharwa kuti ibudise elastic deformation kuti iwane yakavharika. state.Chisimbiso chekaviri eccentric butterfly valve ndeyechinzvimbo chekuisa chisimbiso, zvinoreva kuti nzvimbo yekuisa chisimbiso cheplate yevharuvhu uye chigaro chevharuvhu chiri mumutsara wekubata, uye mhete yekuisa chisimbiso inowanzogadzirwa nerabha kana PTFE.Saka haipokane nekudzvinyirirwa kwepamusoro, uye iko kushandiswa mu-high-pressure system inotungamira mukudonha.
Chii Chikuru Chikamu cheDouble Eccentric Butterfly Valve?
Kubva paMufananidzo Uri Pamusoro, Tinogona Kuona Zviripachena Kuti Zvikamu Zvikuru zveDouble Eccentric Butterfly Valve Ine Zvinotevera Zvinhu Zvinomwe:
Muviri: Imba huru yevhavha, kazhinji yakagadzirwa nesimbi yakakandwa, ductile iron, kana simbi isina tsvina, yakagadzirirwa kuisa mukati mezvikamu zvevhavha.
Disc: Chikamu chepakati chevhavha inotenderera mukati memuviri wevharuvhu kuti idzore kubuda kwemvura.Dhisiki rinowanzo gadzirwa nesimbi yakakandwa, simbi yakakandwa kana bhuronzi uye ine chimiro chakafuratira kana chakakombama kuti chienderane nechimiro chemuviri wevharuvhu.
Shaft Bearings: Shaft Bearings inowanikwa mumuviri wevharuvhu uye inotsigira shaft, ichiibvumira kutenderera zvakanaka uye kuderedza kupokana.
Chisimbiso Mhete: mhete yekuisa chisimbiso yerabha inonamirwa kuplate yevharuvhu neplate yekumanikidza uye simbi isina tsvina screws, uye chiyero chekuisa chisimbiso chevharuvhu chinogadziriswa nekugadzirisa screws.
Chisimbiso Chigaro: chikamu chevhavha inovhara disc uye inodzivirira kubuda kwemvura kuburikidza nevhavha kana yakavharwa.
Dhiraivha shaft: inobatanidza actuator kune vharafu yevhavha uye inotumira simba rinofambisa iro vharuvhu kukwidibira kune yaunoda chinzvimbo.
Actuator: inodzora nzvimbo ye disc mukati memuviri wevhavha.Uye kazhinji akaiswa pamusoro pemuviri wevhavha.
Mufananidzo Kunobva: Hawle
Vhidhiyo inotevera inopa mamwe maonero uye akadzama maonero ekugadzirwa uye chimiro cheviri eccentric butterfly valve.
Zvakanakira uye Zvakaipa Kaviri Eccentric Butterfly Valve
Zvakanakira:
1 Inonzwisisika dhizaini, compact chimiro, nyore kuisa uye disassemble, inochinjika kushanda, kuchengetedza-basa, nyore, uye nyore kugadzirisa.
2 Iyo eccentric chimiro inoderedza kukweshera kwechisimbiso mhete uye inowedzera hupenyu hwebasa revhavha.
3 Yakavharwa zvachose, zero leakage.Inogona kushandiswa mune yakakwirira vacuum mamiriro
4 Shandura zvinhu zvevhavha ndiro chisimbiso, butterfly plate, shaft, nezvimwewo, inogona kuiswa kune akasiyana midhiya uye tembiricha dzakasiyana.
5 Chimiro chechimiro, simba rakakwirira, nzvimbo huru yekufashukira, kushomeka kwekuyerera
Zvakaipa:
Nekuti chisimbiso inzvimbo yekuisa chisimbiso chimiro, chisimbiso chepamusoro pefurafura yefurafura uye chigaro chevharuvhu chiri mumutsara wekubatana, uye chisimbiso chinogadzirwa neiyo elastic deformation inokonzerwa neshavishavi plate inotsikirira chigaro chevharuvhu, saka inoda kuvharika kwakanyanya. chinzvimbo uye ine simba rakaderera rekumanikidza kwakanyanya uye kupisa kwakanyanya.
Iyo Yekushandisa Range yeKaviri Offset Butterfly Valve:
- Kurapa kwemvura nekugovera masisitimu
- Mining industry
- Kuvaka zvikepe nekuchera zvivakwa
- Kemikari uye petrochemical zvirimwa
- Mabhizinesi ezvekudya nemakemikari
- Mafuta uye gasi maitiro
- Nzira yekudzima moto
- HVAC masisitimu
- Zvinwiwa zvisina hutsinye uye magasi (gasi rechisikigo, CO-gasi, zvigadzirwa zvepetroleum, nezvimwewo)
