Butterfly vharafu imhando yevhavha iyo inoshandisa disc mhando kuvhura nekuvhara zvikamu kutenderera nezve 90 ° kuvhura, kuvhara kana kudzora kwepakati kuyerera. Butterfly vharuvhu haisi nyore chete muchimiro, diki saizi, kurema uremu, yakaderera mukushandisa zvinhu, diki mune yekuisa saizi, diki mukutyaira torque, yakapusa uye inokurumidza mukushanda, asi zvakare ine yakanaka kuyerera mutemo mutemo basa uye kuvhara maitiro ekuisa chisimbiso pa nguva imwe chete. Iyo ndeimwe yemhando dzekumhanya kwazvo dzekuvhiya mumakore gumi apfuura. Butterfly mavharuvhu anoshandiswa nevakawanda. Izvo zvakasiyana uye huwandu hwekushandisa kwayo zvichiri kuwedzera, uye iri kukura kusvika kumusoro tembiricha, kumanikidza kwakanyanya, dhayamita yakakura, kuiswa chisimbiso kwakakwirira, hupenyu hwakareba, hunhu hwakanaka hwekugadzirisa, uye kuwanda-kushanda kweimwe vharuvhu. Kuvimbika kwaro uye mamwe maratidziro ekuita asvika padanho repamusoro.
Nekushandisa kwemakemikari anodzivirira ekugadzira rabha muvharufuru vharuvhu, mashandiro evharufuru vharuvhu inogona kuvandudzwa. Chakaita zvokugadzirwa rabha ane hunhu ngura nemishonga, kukukurwa nemishonga, ndeiya yakaita kugadzikana, zvakanaka kushinga, nyore Anoumba uye yakaderera mutengo, uye anogona kusarudzwa maererano siyana zvinodiwa kusangana anodawo ezvinhu ari shavishavi vharafu.
Polytetrafluoroethylene (PTFE) ine yakasimba ngura kuramba, kugadzikana kuita, zvisiri nyore kuchembera, yakaderera kukakavara coefficient, nyore kuumba, kugadzikana saizi, uye kwayo yakazara kuita kunogona kuvandudzwa nekuzadza uye nekuwedzera yakakodzera zvinhu kuti uwane shavishavi vharafu yekuisa chisimbiso zvinhu nesimba riri nani uye yakaderera kukweshera coefficient, iyo inokunda kukwana kweyakagadzirwa synthetic rubber. Naizvozvo, polytetrafluoroethylene (PTFE) ndiyo inomiririra polymer polymer Polymer Composite zvinhu uye yavo yekuzadza yakagadziriswa zvinhu zvave zvichishandiswa zvakanyanya mumavharufuru mavharuvhu, kuitira kuti mashandiro evharufuru mavharuvhu akawedzeredzwa zvakare. Butterfly mavharuvhu ane yakafara tembiricha uye kumanikidza huwandu, hwakavimbika chisimbiso mashandiro uye hwakareba hupenyu hwebasa zvakagadzirwa.
Kuti uwane zvinodikanwa zvekukwirira uye kwakadzika tembiricha, kukukurwa kwakasimba, hupenyu hwakareba uye zvimwe zvinoshandiswa mumaindasitiri, simbi yakavharwa butterfly vharuvhu yakagadziriswa zvakanyanya. Nekushandisa kweyepamusoro tembiricha yekudzivirira, yakaderera tembiricha kuramba, yakasimba ngura kuramba, yakasimba kukwira kudzvinyirira uye yakakwirira simba chiwanikwa zvinhu mumabhururuvharuvhu mavharuvhu, simbi rakanamwa shavishavi mavharuvhu ave achishandiswa zvakanyanya mukukwirira nekudzika tembiricha, yakasimba kukukurwa kwevhu, hupenyu hurefu hwebasa uye zvimwe maindasitiri minda. Butterfly mavharuvhu ane hombe dhayamita (9 ~ 750mm), yakanyanya kumanikidza (42.0mpa) uye yakafara tembiricha renji (- 196 ~ 606 ℃) zvabuda, izvo zvinoita kuti butterfly vharuvhu tekinoroji isvike padanho idzva.
Iyo vhevhuru vharuvhu ine diki kuyerera kuramba kana yakavhurwa zvizere. Kana kuvhura kuri pakati pe15 ° uye 70 ° inogona zvakare kudzora kuyerera zvine mutsindo. Naizvozvo, shavishavi vharuvhu zvinowanzodavirwa kushandiswa mumunda yakakura dhayamita murau.
Sevharufuru vharuvhu disc disc inofamba nekupukuta, saka mazhinji mavharuvhu mavharuvhu anogona kushandiswa neakamiswa akasimba makemikari epakati. Zvinoenderana nesimba rechisimbiso, rinogona zvakare kushandiswa poda uye granular media.
Butterfly mavharuvhu akakodzera kuyerera mutemo. Sezvo kumanikidzwa kurasikirwa kwevhirivhita vharuvhu iri mupombi iri yakati kurei, inova inenge katatu yeiyo yevhavhavhavhavha, simba rekumanikidza kurasikirwa paipiipi sisitimu inofanirwa kutariswa zvizere pakusarudza shavishavi vharuvhu, uye simba rebutafuru ndiro rinotakura pombi yepakati kumanikidza kana kuvhara kunofanirwa kutariswa. Uye zvakare, iyo yekushisa tembiricha inoshanda yezvigaro zvechigaro zvekupisa pane yakanyanya tembiricha inofanirwa kutariswa.
Hurefu hwesimba uye kureba kwakazara kwevhavhavhavhi butterfly idiki, kuvhura nekuvhara yekumhanyisa inomhanya, uye ine hunyanzvi hwekudzivirira emvura. Chimiro musimboti wemavharufuru vharafu inonyanya kukodzera kugadzira hombe dhayamita vharafu. Kana vharuvhu bhatiri ichidikanwa kuti ishandiswe kuyerera kuyerera, chinhu chakakosha ndechekusarudza nemazvo saizi nerudzi rwevhayivhuvhuru, kuti igone kushanda nemazvo uye nemazvo.
Kazhinji, mukumonyoroka, kudzora kudzora uye nepakati matope, mapfupi mamiriro echimiro, kuvhura nekukurumidza nekumhanyisa kumhanya uye yakaderera kumanikidza-kudimburwa (diki musiyano musiyano) inodiwa, uye vharuvhu shavha inokurudzirwa Butterfly vharuvhu inogona kushandiswa munzvimbo mbiri chinja kugadziridzwa, yakaderedzwa dhayeti chiteshi, yakaderera ruzha, cavitation uye vaporization chiitiko, kudonhedza kudiki kumhepo uye hasha svikiro. Kugadzirisa kugadzikana pasi peakakosha mamiriro ekushanda, kana kuomesa chisimbiso, kwakasimba kupfeka uye kwakadzika tembiricha (cryogenic) mamiriro ekushanda anodikanwa.
chimiro
Iyo inowanzo kuverengerwa nemuviri wevharuvhu, tsvimbo yevhavha, ndiro yefurifuru uye yekuisa chisimbiso mhete. Muviri wevhavha iri cylindrical ine pfupi axial kureba uye yakavakirwa-mukati butterfly ndiro.
mamirire
1. Butterfly vharuvhu ine hunhu hweyakareruka mamiriro, diki vhoriyamu, kurema uremu, yakaderera zvinhu kudyiwa, diki yekuisa saizi, nekukurumidza switch, 90 ° kudzosera kutenderera, diki yekutya torque, nezvimwewo inoshandiswa kucheka, kubatanidza uye kugadzirisa iyo yepakati mupombi, uye ine yakanaka fluid kudzora maitiro uye yekuisa chisimbiso mashandiro.
2. Iyo vharuvhu vharuvhu inogona kutakura madhaka uye chengetedza iyo diki mvura pane pombi muromo. Pasi pesimba rekumanikidza, kuiswa chisimbiso kwakanaka kunogona kuwanikwa. Kuita kwakanaka kuita.
3. Iyo yakagadziriswa dhizaini yefurafuru inoita kuti kurasikirwa kwemvura kusagadzikana kuve kudiki, kunogona kutsanangurwa sechigadzirwa-chinoponesa simba.
4. Iyo tsvimbo yevhavha ine yakanaka ngura kuramba uye anti abrasion chivakwa. Kana vharuvhu vharuvhu ikavhurwa uye yakavharwa, tsvimbo yevhavha inongotenderera uye haifambe kumusoro uye pasi. Kurongedza kwetsvimbo yevhavhavha hakusi nyore kukuvara uye kuiswa chisimbiso kwakavimbika. Iyo yakagadziriswa nepini taper yeplate butterfly, uye iyo yekupedzisira magumo yakagadzirirwa kudzivirira iyo vharuvhu tsvimbo kubva kudonha kana iko kubatana pakati pevharuvhu tsvimbo uye shavishavi ndiro inoputsika netsaona.
5. Kune flange yekubatanidza, kiringi yekubatanidza, garo rekuwisira kubatanidza uye lug kiramba yekubatanidza.
Mafomu ekutyaira anosanganisira echinyorwa, honye giya dhiraivha, magetsi, pneumatic, hydraulic uye electro-hydraulic linkage actuator, ayo anogona kuona kure kudzora uye otomatiki mashandiro.
