Muchinyorwa chakapfuura, takataura nezve gedhi uye globe mavharuvhu, nhasi tinoenda kune butterfly mavharuvhu uye cheki mavharuvhu, ayo anowanzoshandiswa pakurapa kwemvura.
1. Butterfly Valve.
Butterfly valveivharuvhu inotenderera inoshandisa dhisiki (inozivikanwawo sendiro yeshavishavi) kuvhura uye kuvhara nhengo kutenderera 90 ° kana nezve 90 ° kuvhura uye kuvhara gwara.Kufamba kwevharuvhu dhisiki kuri kupukuta, saka mavharuvhu mazhinji eshavishavi anogona kushandiswa kunhepfenyuro ane akaturikwa akasimba zvidimbu.
Anowanzo shandiswa butterfly mavharuvhu anosanganisira wafe uye flanged butterfly mavharuvhu.Wafer type butterfly valve inoshandiswa kubatanidza vharafu pakati pepombi mbiri dzepombi dzine mabhaudhi, uye flange rudzi rweshavishavi vharafu ine flange pavharuvhu, uye maflange kumagumo ese evharuvhu akabatana nepombi flange nemabhaudhi.
Features:
1.Ukuru hudiki, hurefu hupfupi, chimiro chiri nyore uye uremu huremu.
2. Zviri nyore kushanda, kuvhura nekukurumidza nekuvhara, zvinongoda kutenderera disc 90 ° kuvhura nekuvhara.
3. Kuiswa chisimbiso kwakanaka uye kugadzirisa kushanda.Nekuti rabha inoshandiswa semhete yekuisa chisimbiso, kudzvanya uye kusimba kwakanaka (kureva kuti, haizoomese), saka yekuisa chisimbiso yakanaka..Iyo valve flap inogona kuvhurwa pakati pe15 ° ne70 °, uye inogona kuita inonzwisisika kuyerera kwekutonga.
4. Diki rekushandisa torque uye kusagadzikana kwemvura.Maererano nezviyero, kupikisa kwemvura yevhavhavhavhavha ishoma pane yemamwe marudzi emavharuvhu kunze kwemavharuvhu ebhora.
5. Pamusana pekugumira kwezvinhu zvekuisa chisimbiso, kushandiswa kwekushanda uye kushanda kwekushisa kwevheji ye butterfly zvishoma.
2.Check Valve
Zvishandiso uye maitiro:
Tarisa vharafuivharuvhu inoshandiswa kudzivirira kuyerera kwemedia mupombi, inovhura kana yepakati ichiyerera ichidzika nekudzika uye inovhara yega kana yepakati ichiyerera ichidzokera kumashure.Kazhinji inoshandiswa mupombi haibvumiri iyo yepakati kuti idzerere yakatarisana, kuitira kudzivirira kudzoka kwepakati kukuvara kwemidziyo uye zvikamu.Kana pombi yamira kushanda, usakonzerese kudzoka kwepombi inotenderera.Mupombi, kazhinji tarisa mavharuvhu uye akavharwa-yedunhu mavharuvhu anoshandiswa munhevedzano.Izvi zvinokonzerwa nekuvharwa kwakashata kwevhavhavha yecheki, apo mhirizhonga yevhidhiyo inenge iduku, pachava nechikamu chiduku chekuputika kwevhidhiyo, kudiwa kwevhavha-yevhavhavha yevhavha kuitira kuti pave nekuvhara kwepombi.Pazasi vharafu iriwo cheki vharafu, inofanira kunyudzwa mumvura, yakanyatsoiswa mupombi haigoni kuzvidzora-priming kana pasina vacuum kupomba mvura kusveta pombi pamberi.
Mvura yekurapa vharafu zvakajairika kukundikana uye zviyero
Valve mukushanda kwepombi kwenguva yakati, pachava nekukundikana kwakasiyana-siyana.Kutanga, nhamba yezvikamu zvine chokuita nekuumbwa kwevhavha, zvikamu zvakawanda zvinowanzokundikana.Chechipiri, nekugadzirwa kwevharuvhu, kugadzira, kuisirwa, mamiriro ekushanda, mabhenefiti ekuchengetedza uye nekuipa.General isiri-simba-inotyairwa vharafu zvakajairika kukundikana akakamurwa muzvikamu zvina.
1.Transmission kukundikana
Kutadza kwemuchina wekutapurirana kunowanzo kuratidzwa sevharupu hunde jamming, kushanda kusingachinjiki kana vharafu haigone kushanda.Zvikonzero ndezvi: valve yakavharwa kwenguva yakareba mushure mekuita ngura;kuiswa uye kushanda kwekukuvadza kusina kunaka kune tambo dze stem kana stem nut;gedhi rakaputirwa mumuviri wevharuvhu nezvinhu zvekunze;gedhi rinowanzo hafu-yakavhurika uye hafu-yakavharwa mamiriro, nemvura kana zvimwe zvinokanganisa zvinotungamira kune stem screws uye stem nut waya kusarongeka, kusunungura, kuruma chiitiko;kurongedza kudzvinyirira kwakanyanya, kubata tsinde;dzinde rinoiswa pamusoro kana nekuvhara kwezvikamu zvakajairirwa.Maintenance inofanira kuva lubricated drive parts.Nerubatsiro rwe wrench, uye zvinyoro nyoro, unogona kubvisa chiitiko chejamming, topping;kumisa kugadziriswa kwemvura kana kuchinjwa kwevhavha.
2.Kuparara kwevhavha yemuviri kuputika
Valve muviri wakakuvadzwa kuputsika zvikonzero: vharafu zvinhu ngura kuramba kuderera;pombi nheyo kugadzirisa;pombi network pressure kana tembiricha musiyano kuchinja;sando yemvura;kuvhara vharafu kushanda kusina kunaka uye zvichingodaro.Inofanira kukurumidza kubvisa zvikonzero zvekunze uye kutsiva mhando imwechete yezvikamu zvevharuvhu kana mavharuvhu.
3. Kubuda kwevhavha
Kudonha kwevhavha kunoratidzwa se: valve stem core leakage;gland kubuda;flange gasket leakage.Zvikonzero zvinowanzoitika ndezvi: hunde yevharuvhu (shaft shaft) kupfeka, corrosion spalling, kuvhara makomba epamusoro, kupenengura chiitiko;chisimbiso kuchembera, kuvuza;gland mabhoti, flange mabhaudhi akasununguka.Kuchengetedza kuwedzera, kutsiva chisimbiso chepakati;tsiva nati nyowani kuti ugadzirise nzvimbo yebhaudhi yekusimbisa.
Hazvina mhosva kuti rudzii rwekukundikana kana kugadziriswa kwakajairika, kugadzirisa hakuna nguva, kunogona kukonzera tsvina yemvura, kana kuipa, kunokonzera hurongwa hwose kuoma mitezo.Nokudaro, vashandi vekuchengetedza valve vanofanira kunge vari pane zvikonzero zvekukundikana kwevhavha kuita basa rakanaka, unyanzvi uye mutemo wakarurama uye kushanda kwevhavha, nguva yakakodzera uye yakanyatsogadziriswa yekukanganisa kwakasiyana-siyana kwekukurumidzira, kuchengetedza kushandiswa kwemaitiro ehutano hwemvura.
4.vharuvhu kuvhura uye kuvhara kwete zvakanaka
Kuvhura kwevhavha nekuvhara kuita kwakashata kwevhavha haina kuvhurika kana kuvharwa, vharafu haigone kushandirwa zvakajairika.Zvikonzero ndezvi: vharafu stem corrosion;gedhi rakamisikidzwa kana gedhi rakavharwa kwenguva yakareba mumamiriro emarara;gate off;zvinhu zvekune dzimwe nyika zvakanamira munzvimbo yekuisa chisimbiso kana kuvhara groove;kutapurirana zvikamu kupfeka, jamming.Kusangana nepamusoro pekugadzirisa mamiriro, lubrication transmission parts;kudzokorora kuvhura nekuvhara vharuvhu uye hydrodynamic kukanganisa kwezvinhu zvekunze;kutsiva kwevhavha.
