Sezvo zita rayo rinoratidzira, vheji yebhora ine bhora-rakafanana nedhisiki rinoita sechivharo kana vharuvhu yakavharwa.Makambani anogadzira mavharuvhu ebhora anowanzo gadzira vharafu kuti ive quarter-turn valve asi inogona zvakare kuve inotenderera mhando kana ichidzora kana kutsausa kuyerera kwe media.

Mavharuvhu ebhora anowanzo shandiswa mumashandisirwo anoda kuvharwa kwakasimba.Ivo vanozivikanwa kuva ne-low-pressure madonhwe.Iyo 90-degree inotendeuka inoita kuti zvive nyore kushanda kunyangwe midhiya iine yakakwira vhoriyamu, kudzvanywa kana tembiricha.Ivo vane hupfumi zvakanyanya nekuda kwehupenyu hwavo hwesevhisi hurefu.

Mavharuvhu ebhora akanakira magasi kana zvinwiwa zvine tunhu tudiki.Aya mavharuvhu haashande zvakanaka nema slurries sezvo ekupedzisira achikuvadza zviri nyore zvigaro zve elastomeric.Kunyange ivo vaine masimba ekukwenya, mavharuvhu ebhora haashandiswe akadaro nekuti kukwesha kubva mukupuruzira kunogona kukanganisa zvigaro zvakare.

Zvikamu zveBhora Valve

Kune zvakawanda zvakasiyana-siyana zvemavharuvhu ebhora, senge 3-nzira bhora vharafu uye bhora mavharuvhu mune zvakasiyana zvinhu.Muchokwadi, 3-nzira bhora vharafu yekushanda nzira yakasiyanawo neyakajairika bhora vharafu.Kune nzira dzakawanda dzekuisa mavharuvhu.Iva sezvazvinogona, kune zvikamu zvinomwe zvevharuvhu zvakajairika kune ese mavharuvhu.

Muviri

Muviri ndiwo hurongwa hwevharuvhu yese yebhora.Inoita sechipingamupinyi kune mutoro wekumanikidza kubva kune midhiya saka hapana kutamiswa kwekumanikidza kune mapaipi.Inobata zvinhu zvose pamwe chete.Muviri wakabatana nepombi kuburikidza neshinda, mabhaudhi kana akasungwa majoini.Mavharuvhu ebhora anogona kuverengerwa zvinoenderana nerudzi rwemuviri, unowanzo kukandwa kana kufoshwa.

Stem

Kuvhura kana kuvhara kwevhavha kunopiwa ne stem.Izvi ndizvo zvakare zvinobatanidza bhora disc kune lever, mubato kana actuator.Dzinde ndiro rinotenderedza bhora richivhura kana kuvhara.

Packing

Iri ndiro gasket rinobatsira kuvhara bhoneti uye dzinde.Nyaya zhinji dzinoitika munzvimbo iyi saka kuisirwa kwakakodzera kwakakosha.Kunyanya kusununguka, kuvuza kunoitika.Kunyanya kusimba, kufamba kwehunde kunorambidzwa.

Bonnet

Bhoneti ndicho chifukidziro chekuvhura kwevharuvhu.Izvi zvinoshanda sechipiri chipingamupinyi chekumanikidza.Bhoneti ndiro rinobata zvinhu zvese zvemukati pamwechete mushure mekunge izvi zvapinzwa mukati memuviri wevharuvhu.Kazhinji inogadzirwa kubva kuzvinhu zvakafanana nemuviri wevharuvhu, bhoneti inogona kunge yakaumbwa kana kukandwa.

Bhora

Iri ndiro dhisiki revhavha yebhora.Kuva yechitatu inonyanya kukosha muganhu wekumanikidza, kudzvinyirirwa kwevezvenhau kunobata dhisiki kana iri munzvimbo yakavharwa.Madhisiki ebhora anowanzo gadzirwa nesimbi yakaumbwa kana chero chinhu chakasimba.Bhora dhisiki rinogona kuturikwa senge vharafu yebhora inoyangarara, kana kuti inogona kugadzikwa senge yetrunnion-yakaiswa bhora vharafu.

Seat

Dzimwe nguva dzinonzi zvindori zvechisimbiso, apa ndipo panozorora bhora.Zvichienderana nekugadzirwa kwebhora disc, chigaro chinosungirirwa kana kwete kubhora.

Actuator

Actuators zvishandiso zvinogadzira kutenderera kunodiwa nevhavhavha yebhora kuvhura disc.Kazhinji, izvi zvine simba.Mamwe ma actuator anogona kudzorwa ari kure saka mavharuvhu achiri kushanda kunyangwe aya ari munzvimbo dziri kure kana dzakaoma kusvika.

MaActuator anogona kuuya semavhiri emaoko emavharuvhu ebhora anoshanda nemaoko.Mamwe mamwe marudzi emagetsi anosanganisira solenoid mhando, pneumatic mhando, hydraulic marudzi, uye magiya.

Bharavhavha Inoshanda Sei?

Kazhinji kutaura, bhora rekushanda kwevhavha rinoshanda nenzira iyi.Ingave inoitwa nemaoko kana actuator, imwe simba inofambisa lever kana mubato kuenda kukota kutendeuka kuvhura vharuvhu.Simba iri rinotamirwa kune hunde, richifambisa disc kuti rivhure.

Iyo bhora disc inotendeuka uye divi rayo rine gomba rakatarisana nekuyerera kwe media.Panguva ino, lever iri munzvimbo yeperpendicular uye chiteshi kuti chienderane maererano nekuyerera kwenhau.Pane chinomira chemubato padhuze nekubatana pakati pehunde nebhoneti kungobvumira kota-kutendeuka.

Kuti uvhare vharafu, lever inodzokera kumashure kwekota.Dzinde racho rinofamba kushandura bhora dhisiki richienda kune rimwe divi, richivharira kuyerera kwe media.Iyo lever iri munzvimbo yakafanana uye chiteshi, perpendicular.

Nekudaro, cherechedza kuti kune matatu marudzi ebhora disc kufamba.Chimwe nechimwe cheizvi chine maitiro akasiyana ekushanda.

Varuvhu yebhora inoyangarara ine dhisiki rebhora rakarembera pahunde.Ikoko hakuna tsigiro pazasi chikamu chebhora saka bhora dhisiki zvishoma rinotsamira pakumanikidzwa kwemukati kweiyo tight chisimbiso bhora mavharuvhu anozivikanwa.
Sezvo vharuvhu ichivharwa, mutsara wemutsetse wekumusoro unobva kunhepfenyuro unosundira bhora kuchigaro chakadzikira pasi.Izvi zvinopa iyo yakanaka valve tightness, inowedzera kune yayo yekuisa chisimbiso.Chigaro chepasi cheiyo inoyangarara bhora dhizaini inotakura mutoro wekumanikidza kwemukati kana vharafu yakavharwa.

Imwe mhando yebhora disc dhizaini ndiyo trunnion yakaiswa bhora vharafu.Izvi zvine seti yematrunnions pazasi pebhora disc, zvichiita kuti bhora dhisiki rimire.Aya ma trunnions anotorawo simba kubva pakumanikidza mutoro kana vharafu inovhara kuitira kuti pave nekukwevera kushoma pakati pebhora disc nechigaro.Kuvhara chisimbiso kunoitwa mune ese ari maviri kumusoro uye kuzasi madoko.

Kana vharuvhu ichivharwa, zvigaro zvakatakurwa nechitubu zvinofamba zvichipesana nebhora rinongotenderera muakisi yaro.Zvitubu izvi zvinosundidzira chigaro zvakasimba kubhora.Trunnion mounted ball types dzakakodzera maapplications asingade high pressure kutamisa bhora kuchigaro chezasi.

Chekupedzisira, inosimuka stem bhora vharafu inoshandisa tilt-and-turn mechanism.Bhora dhisiki rinomira kuchigaro kana vharuvhu yavhara.Painovhura, dhisiki inotenderera kuti ibvise pachayo kubva pachigaro uye inobvumira midhiya kuyerera.
