Butterfly valve

Ivharuvhu yeshavishavi ndeyechikamu chekota. Quarter mavharuvhu anosanganisira marudzi evharuvhu anogona kuvhurwa kana kuvharwa nekushandura dzinde kota. Inbutterfly mavharuvhu, pane dhisiki rakabatanidzwa pahunde. Kana tsvimbo inotenderera, inotenderera disc nekota, zvichiita kuti disc iwire perpendicular kune mvura uye inomira kuyerera. Kuti udzorere kuyerera, tsinde inotenderedza diski kudzokera kunzvimbo yayo yepakutanga, kure nekuyerera.

Butterfly mavharuvhu isarudzo yakakurumbira nekuti iri nyore kuisa, isingadhure, uye inowanikwa mune dzinenge hukuru hwese. Izvi zvinowanzo shandiswa sekutonga masevhisi uye zvinangwa zvekuchinja.

Butterfly valve application

Butterfly mavharuvhu akakosha kune maitiro uye mashandiro mumaindasitiri mazhinji akasiyana. Izvi zvinokonzerwa nehukuru hwavo uye kugona kudzora kuyerera kwemvura, gasi nemadhaka. Mavharuvhu eshavishavi haangogumiri kana kutanga kuyerera, asiwo anodzika kana kuderedza kuyerera sezvinodiwa kana avhurwa zvishoma.

Vatengi kubva kumaindasitiri akawanda vanotenga butterfly mavharuvhu, kusanganisira ayo ari muminda yekugadzira chikafu (mvura), zvidyarwa zvemvura, kudiridza, kugadzira pombi, kugadzira maindasitiri, masisitimu ekudziya uye kutakura kwemakemikari.

Kunyange zvazvo mavharuvhu e butterfly ane akawanda akasiyana anogoneka maapplications, mamwe maapplication chaiwo anosanganisira vacuum, kudzoreredza mafuta, compressed air service, air and water cooling, HVAC, dope service, high-pressure water service, high-temperature service, steam service and fire protection.

Nekuda kwekusiyana kwekugadzira uye zvigadzirwa, butterfly mavharuvhu ane huwandu hwakawanda hwekushandisa. Izvi zvinogona kuiswa mune chero pombi, kubva mumvura yakachena kusvika pakukuya mvura kana slurry. Izvi zvinowanzo shandiswa mumadhaka kana sludge application, vacuum services, steam services, mvura inotonhorera, mweya, kana gasi.

Zvakanakira uye zvisingabatsiri zvevhavhavhavhavha

Butterfly mavharuvhukupa vashandisi nezvakanakira zvakawanda. Kutanga, ivo vane compact dhizaini. Nekuda kweiyo compact dhizaini, inoda shoma nzvimbo yekushanda pane mamwe mavharuvhu mazhinji. Chechipiri, mari yekuchengetedza yevhavhavhavhavhavha yakaderera. Chechipiri, vanopa huwandu hwemhando yepamusoro traffic traffic. Zvakare, haabvi, asi anogona kuvhurwa nyore kana zvichidikanwa. Imwe mukana wevhavhavhavhavha ndiyo mutengo wayo wakaderera.

Zvakanakira butterfly valve

1. Nemhaka yehukuru hwavo hudiki uye compact design, mari yekuisa yakaderera zvikuru.

2. Mavharuvhu aya anotora nzvimbo shoma kana zvichienzaniswa nemamwe mavharuvhu.

3. Automatic actuation inoita kuti ikurumidze uye inobudirira kupfuura mamwe mavharuvhu.

4. Pamusana pekugadzirwa kwema disc akawanda uye zvikamu zvishomanana zvinofamba, zvinoda kugadziriswa zvishoma, nokudaro kuderedza zvakanyanya mamiriro ekunze.

5. Zvinhu zvakasiyana-siyana zvechigaro zvinoita kuti zvive nyore kushandisa mumarudzi ose emamiriro ezvinhu, kunyange nzvimbo dzakasvibiswa.

6. Butterfly valves inoda zvinhu zvishoma, zviri nyore kugadzira nekugadzira, uye zvinowanzodhura zvakanyanya kudarika mamwe marudzi emavharuvhu.

7. Butterfly valves inogona kushandiswa mumhando dzakasiyana-siyana, kusanganisira kuisa pasi pevhu.

Kuipa kwevhavhavhavhavha

Zvechokwadi, zvisingabatsiri zvevhavhavhavhavhavha inodarika zvakanakira. Asi usati washandisa mavharuvhu aya, pachine zvimwe zvinhu zvekuyeuka.

1. Kunyange kana yakazaruka zvakakwana, nzvimbo duku ye disc ichadzivirira kuyerera kwezvinhu. Izvi zvinogona kukanganisa kufamba kweiyo disc chinzvimbo uye kudzvanywa switch mupombi.

2. Basa rekuisa chisimbiso harina kunaka semamwe mavharuvhu.

3. Throttling inongoshanda kune yakaderera differential pressure service.

4. The butterfly valve nguva dzose ine ngozi yekuvhara kuyerera kana cavitation.

Butterfly valve structure

Butterfly mavharuvhu ane akati wandei hunhu. Izvi zvinosanganisira muviri, disc, stem, uye chigaro. Ivo zvakare vane actuator, senge lever. Mushandi anogona kutenderedza valve actuator kuti achinje nzvimbo ye disc.

Muviri wevharuvhu wakaiswa pakati pemapipe maviri epombi. Iyo yakajairika pane ese akasiyana madhizaini emuviri malugs nemadhisiki.

Nheyo yekushanda yevhavha disc yakafanana negedhi muvharuvhu yegedhi, plug muvhavhavha yeplug, bhora mukatibhora vharafu, etc. Kana ichitenderedzwa 90 ° kuyerera parallel kune fluid, disc iri munzvimbo yakazaruka. Munzvimbo iyi, dhisiki inobvumira kuti mvura yose ipfuure. Kana iyo disc inotenderera zvakare, dhisiki inopinda munzvimbo yakavharwa uye inodzivirira kubuda kwemvura. Zvichienderana ne disc orientation uye dhizaini, mugadziri anogona kushandura torque yekushandisa, chisimbiso uye / kana kuyerera.

Dzinde revharuvhu ishaft. Inogona kuva chikamu chimwe kana zviviri. Kana iri iyo yekupedzisira, inodaidzwa kunzi split stem.

Chigaro chakabatana nemuviri wemotokari nekutsikirira, kubatanidza kana kuvhara nzira. Mugadziri anowanzo gadzira chigaro chevharuvhu nepolymer kana elastomer. Chinangwa chechigaro chevhavha ndechekupa basa rekuvhara kwevhavha. Ichi ndicho chikonzero simba rinotenderera rinodiwa pakuvhara vhavhavhavhavha richinzi “seat torque”, ukuwo simba rinotenderera rinodiwa kuti shavishavi vheruvhu ritenderedze chinhu charo rinovhara rinonzi “off seat torque.

Iyo actuator inogona kuve yemagetsi kana otomatiki, uye kuyerera kuburikidza nepombi kunogona kugadziriswa nekufambisa dhisiki yevhavha. Kana yakavharwa, dhisiki yevhavha inovhara gomba revhavha, uye mvura inogara ichibata dhisiki yevhavha. Izvi zvichaita kuti pressure iderere. Kuti uchinje nzvimbo yedhisiki kuti ipe nzira yekuyerera kwemvura, shandura dzinde riite kota.
