Butterfly valve kusarudzwa, kushandisa kwakakodzera uye kugadzirisa gwara

Butterfly mavharuvhu ikota-turn flow control midziyo inoshandisa simbi disc inotenderera ichitenderedza tsinde axis. Iwo anokurumidza kuita kuyerera kuyerera mavharuvhu anobvumira 90 madhigirii ekutenderera kufamba kubva kuvhurika zvakazara kusvika kwakavharika nzvimbo. Kana iyo diski iine perpendicular kune centreline yepombi, valve iri munzvimbo yakavharwa.Apo diski inofananidzwa nechepakati pepombi, valve ichave yakazaruka zvakakwana (kubvumira huwandu hwemvura inoyerera) . control mechanism (disk) inenge yakaenzana nehupamhi hwemukati wepombi iri pedyo. Aya mavharuvhu anouya muhukuru hwakasiyana uye magadzirirwo anotarisisa mashandiro avo mumaindasitiri maitiro ekushandisa; utsanana vharafu kushandiswa; mabasa emoto; kudziyisa, kufefetedza, uye air conditioning (HVAC) masisitimu; uye slurries.Broadly kutaura, butterfly mavharuvhu anokosha pakugadzirisa kuyerera uye kuyerera kwega. Kufamba kwedhisiki kunotanga, kunonotsa kana kumisa kuyerera kwemvura.Zvishandiso zvinoda kunyatsojeka kwepamusoro zvinoenderana nemavharuvhu e butterfly anotarisisa mamiriro epombi, kuvhura kana kuvhara vharavha sezvinodiwa kuchengetedza kuyerera kwakafanana.Mavharuvhu ebutterfly anoshandiswa pakuyerera chimwe chezvinhu zvinotevera zvinoyerera: • Pedyo nemutsara - chiyero chekuyerera chinoenderana neangular motion ye disc.Semuyenzaniso, kana disc iri 40% yakazaruka, kuyerera kuri 40% yehukuru.Ichi chimiro chekuyerera chinowanikwa mupamusoro. kushanda butterfly mavharuvhu. • Kukurumidza kuvhura - Ichi chimiro chekuyerera chinoratidzwa kana uchishandisa resilient seated butterfly valves.Kuyerera kwemvura kunowedzera kana diski inofamba kubva panzvimbo yakavharwa.Sezvo valve inosvika panzvimbo yakazaruka zvakakwana, kuyerera kunodonha zvishoma nezvishoma nekuchinja kuduku. • Flow Isolation - Mavharuvhu eButterfly anogona kupa on/off fluid service.Kuyerera kwega kwega kunodiwa pese apo chimwe chikamu chepombi chinoda kugadziriswa. Butterfly mavharuvhu akakodzera kushandiswa kwakasiyana nekuda kwekureruka kwekugadzira uye kukurumidza kushanda.Soft-seated butterfly mavharuvhu akanakira kuderera kwekushisa, kuderera kwekumanikidza kushandiswa, nepo simbi-yakagara butterfly mavharuvhu ane yakanaka yekuisa chisimbiso pakubata yakaoma mvura mamiriro.Iyi nzira inoshanda. patembiricha yakakwira uye kumanikidzika uye inotakura zvinwiwa zvinoodza kana kuti zvinoparadza.Zvakanakira mavharuvhu eshavishavi zvinosanganisira: • Kuvakwa kwakapfava uye kwakamanikana - Bhavhavhavhavharuvhu inoshandisa simbi yakatetepa sedhisiki yekudzora kuyerera.Madhisiki madiki uye anotora nzvimbo shoma, asi akasimba zvakakwana kuti agadzirise kufamba kwemvura.Mavharuvhu aya ane muviri wakabatana uchiita kuti akwanise kushandiswa mumapombi munzvimbo dzakamanikana.Mapaipi makuru-dhayamita anoda mavharuvhu makuru achishandisa zvinhu zvakawanda zvekugadzira, kuwedzera mari.Ivhavhavha yeshavishavi inenge isingadhuri. kupfuura vharafu yebhora yehukuru hwakafanana nekuti inopedza zvinhu zvishoma kugadzira. • Kuisa Chisimbiso Nekukurumidza uye Kunobudirira - Mavharuvhu eButterfly anoisa chisimbiso chinokurumidza pa actuation, zvichiita kuti ave akakodzera kune yakanyanya kuyerera maapplications.Kuisa chisimbiso chevhavhavhavhavhavha inotsamira pamhando yedhisiki yekubvisa uye chimiro chechigaro.A zero offset butterfly valve. ichapa chisimbiso chakakwana chekushandiswa kwepasi-kusvika 250 pounds per square inch (psi) .Ivhavha yekaviri inogadzirisa inopa chisimbiso chakanakisisa kune maitiro kusvika ku 1,440 psi.Mavharuvhu matatu ekugadzirisa anopa chisimbiso chekushandiswa kwekuyerera pamusoro pe1,440 psi. • Low Pressure Drop uye High Pressure Recovery - Mavharuvhu eButterfly ane low pressure drop zvisinei nekuti dhisiki rinogara riri mumvura. mvura yekudzosa simba nekukurumidza mushure mekunge yabuda muvharuvhu. • Mavharuvhu eButterfly ane zvikamu zvishoma zvemukati. Haana homwe anogona kuteya zvinwiwa kana marara, nokudaro, anoda kupindira kushoma kwekugadzirisa.Kuiswa kwawo kwakangoreruka sezvavanoda kusungirira pakati pepombi flanges dziri pedyo.Hapana yakaoma yekuisa maitiro. senge welding inodiwa. • Kushanda Kuri Nyore - Nekuda kwekukura kwawo uye kureruka kwawo, mavharuvhu eshavishavi anoda torque yakaderera kuti ashande.Madhisiki esimbi matete anoshandisa simba shoma kuti akunde kusamira kwemvura.Mavharuvhu eButterfly ari nyore kuita automate ipai torque yakakwana pakushanda kwavo.Izvi zvinoshandura kuva mari shoma yekushanda - zviduku zvinoshandisa simba zvishoma uye zvinodhura zvishoma kuwedzera kune valve. • Butterfly valves inokonzerwa ne cavitation uye yakavharidzirwa kuyerera - munzvimbo yakazaruka, valve haina kupa chiteshi chakazara.Kuvapo kwe diski mumugwagwa wekuyerera kwemvura kunowedzera kuumbwa kwemarara kumativi evhavha, kuwedzera kukwanisa kwe cavitation.Ball valves. ndeimwe nzira yekushandiswa kwemvura inoda madoko akazara. • Kukurumidza kuora mumasevhisi emvura inonzi viscous fluid - zvinwiwa zvinopeperetsa mavharuvhu eshavishavi pazvinoyerera nemaari.Nekufamba kwenguva, madhisiki anoderera uye haachakwanise kupa chidhindo.Kuora kunenge kwakakwira kana uchibata viscous fluid masevhisi.Gedhi nemavharuvhu ebhora zvinenge zviri nani. kuramba kupfuura butterfly mavharuvhu. • Haikodzeri kuvhuvhuta kwepamusoro - vheji inofanira kungoshandiswa pakuputika mumagetsi mashoma, zvishoma kusvika ku30 degrees kusvika ku80 madhigirii ekuvhura. Mavharuvhu eGlobe ane simba rinoputika kupfuura butterfly valves. Iyo vharafu inoputika munzvimbo yakazaruka yakazara inodzivirira kucheneswa kwehurongwa uye inodzivirira nguruve yemutsetse ine butterfly valve. The kugadzwa chinzvimbo shavishavi vharafu kazhinji pakati flanges.Butterfly mavharuvhu anofanira kuiswa kanenge mana kusvika matanhatu pombi diameters kubva discharge nozzles, gokora, kana mapazi kuderedza migumisiro nyonganyonga. Usati waiswa, chenesa mapaipi uye tarisa flanges kuitira kutsetseka / flatness.Iva nechokwadi chokuti mapaipi akaenzana.Paunenge uchiisa valve, chengetedza diski munzvimbo yakazaruka zvishoma.Flanges inogona kuwedzerwa kuti irege kukuvadza panzvimbo yechigaro.Shandisa pilot. maburi kana zvipfuramabwe zvakatenderedza muviri wevharuvhu paunenge uchisimudza kana kufambisa vharafu.Rega kusimudza vharafu pachibatiso kana mushandisi wayo. Gadzirisa vharuvhu nebhaudhi rekuisa yepombi iri pedyo.Simbisa mabhaudhi nemaoko, wobva washandisa chipanera che torque kuti usimbise mabhaudhi zvishoma nezvishoma uye zvakaenzana, uchifungidzira kujeka pakati pavo neflange.Shandisa vharafu kunzvimbo yakazaruka zvakakwana uye shandisa. chipanera che torque kuti usimbise mabhaudhi kuti utarise kana kunetsana pamabhaudhi. Kugadziriswa kwemavharuvhu kunosanganisira mafuta emagetsi emagetsi, kuongorora uye kugadziriswa kwemagetsi.Mavharuvhu anoda periodic lubrication anosanganisira mafittings emafuta.Inokwana lithium-based grease inofanira kuiswa panguva dzinokurudzirwa kuderedza ngura nekuora. Zvakakoshawo kugara uchiongorora actuator kuti uone chero zviratidzo zvekupfeka kana kusununguka kwemagetsi, pneumatic kana hydraulic connections zvinogona kukanganisa kushanda kwevhavha. Mukuwedzera, mushandisi anofanira kuchenesa zvikamu zvose zvevhavhavhavhavhavha nesilicone-based lubricant.Chigaro chinofanira kuongororwa kune chero zviratidzo zvekupfeka uye kuchinjwa kana zvichidiwa.Butterfly valve discs inoshandiswa mumashandisi akaoma akadai sekushanda kwemhepo yakamanikidzwa inoda mafuta. Butterfly mavharuvhu anotenderera zvisingaite anofanirwa kushandiswa kamwechete pamwedzi. Kusarudzwa kwevharuvhu kungaita sekunge kusarudzwa uye kuita basa rekubatanidza, asi kune akati wandei maitiro ehunyanzvi ekufunga.Yekutanga inosanganisira kunzwisisa rudzi rwekudzorwa kwemvura inodiwa uye rudzi rwesevhisi fluid.Corrosive fluid services inoda mavharuvhu akagadzirwa nesimbi isina tsvina, nichrome, kana zvimwe zvinhu zvinodzivirira kuora. Vashandisi vanofanira kufunga nezvesimba, kudzvanywa uye tembiricha shanduko yepombi uye mwero weotomatiki unodiwa.Kunyange zvazvo mavharuvhu e butterfly achishanda achinyatso kudzora kuyerera, anodhura kupfuura mamwe anoshandiswa nemaoko.Mavharuvhu eButterfly haadzoreki uye haapi. chiteshi chakazara. Kana mushandisi asina chokwadi nezve kuenderana kwemakemikari kwemaitiro kana actuation sarudzo, inokwanisa kambani yevharuvhu inogona kubatsira mukuona kusarudzwa kwakaringana.
