Iwe unofanirwa kusarudza valve yebhora, asi zvakasiyana-siyana zvinorema. Kutora mhando isiriyo kunogona kureva kusakwana, kudonha kweramangwana, kana system inonetsa kuchengetedza.
Iwo mana emhando dzekutanga dzebhora mavharuvhu akaiswa muzvikamu nekuvakwa kwemuviri wavo: imwechete-chidimbu,zvidimbu zviviri, zvidimbu zvitatu, uye kumusoro-kupinda. Imwe neimwe dhizaini inopa chiyero chakasiyana chemutengo, simba, uye nyore kugadzirisa, ichizvigadzirisa kune chaiyo maapplication uye kugadzirisa zvinodiwa.
Kunzwisisa mhando dzemhando idzi inhanho yekutanga, asi ingori mavambo. Ndinowanzoita hurukuro iyi naBudi, maneja akakosha wekutenga wandinoshanda naye kuIndonesia. Vatengi vake vanovhiringidzika nemashoko ese. Anoona kuti kana achinge akwanisa kutsanangura misiyano yepakati nenzira iri nyore, vatengi vake vanonzwa vane chivimbo. Vanogona kubva pakusava nechokwadi kuenda pakuita sarudzo yenyanzvi, vangave vari kutenga vharafu iri nyore yetambo yekudiridza kana imwe yakaoma kwazvo yekugadzira maindasitiri. Ngatitaurei kuti mhando idzi dzinonyatsorevei kwauri.
Ndeapi marudzi akasiyana ebhora mavharuvhu?
Iwe unoona mazwi akadai sekuti "chiteshi chakazara," "trunnion," uye "bhora rinoyangarara" pamapepa chaiwo. Iyi tekinoroji jargon inoita kuti zviome kuziva kana uri kuwana kuita kwakaringana kune zvaunoda chaizvo.
Kupfuura chimiro chemuviri, mavharuvhu ebhora anotaipa nehukuru hwawo (full port vs. standard port) uye kugadzirwa kwebhora remukati (inoyangarara vs. trunnion). Chiteshi chakazara chinovimbisa kuyerera kusingatadzirwe, nepo trunnion dhizaini inobata yakanyanya kudzvinyirira.
Ngatinyure zvakadzika mune zvese muviri nemhando dzemukati. Kuvakwa kwemuviri kune zvese nezvekuwana kuchengetedza. Achidimu chimwevharafu inhengo yakavharwa; haidhure asi haigadzirike. Azvidimbu zvivirimuviri wevharuvhu unotsemuka nepakati, zvichibvumira kugadziriswa, asi unofanira kutanga wabvisa kubva papombi. Iyo yakanyanya kugadzirisa-inoshamwaridzika dhizaini ndeyezvidimbu zvitatuvharafu. Chikamu chepakati chine bhora chinogona kubviswa nekusunungura mabhaudhi maviri, zvichisiya kubatana kwepombi.

Astandard portidiki zvishoma, izvo zvakanaka kune akawanda maapplication. Pakupedzisira, anenge ese mavharuvhu ebhora ePVC anoshandisa abhora rinoyangararadhizaini, uko kudzvanywa kwehurongwa kunosundidzira bhora zvakachengeteka kurwisa chigaro chepasi kuti chigadzire chisimbiso.
Bhora Varuvhu Mhando paKutarisa

Ndeapi marudzi akasiyana ekubatanidza bhora vharafu?
Wawana vharafu yakakwana, asi ikozvino unofanirwa kuibatanidza. Kusarudza nzira isiriyo yekubatanidza kunogona kutungamira kumisikirwo inonyengera, kunoramba kudonha, kana sisitimu yausingakwanise kushandira pasina hacksaw.
Mhando dzekubatanidza dzinonyanya kuzivikanwa dzemavharuvhu ebhora ndeye solvent-weld sockets for a permanent PVC bond, threaded ends ekubatanidza zvinhu zvakasiyana, flanged mapombi makuru, uye true union connections for maximum serviceability.
Mhando yekubatanidza yaunosarudza inotsanangura kuti valve inobatanidza sei nemapombi ako.Socketkana "kutsvedza" zvinongedzo zvinoshandiswa paPVC pombi, kugadzira chigarire, chisionekwi chisungo chichishandisa simende inonyungudutsa. Izvi zviri nyore uye zvakavimbika zvikuru.Threadedzvinongedzo (NPT kana BSPT) zvinokutendera kuti uvhare vharuvhu papombi yakarukwa, iyo yakanaka kubatanidza PVC kune zvinhu zvesimbi, asi zvinoda tambo sealant uye kunyatsoiswa kuti isabuda. Kune mapaipi makuru (kazhinji anopfuura 2 inches),flangedzvisungo zvinoshandiswa. Vanoshandisa mabhaudhi uye gasket kugadzira chisimbiso chakasimba, chakachengeteka, uye chinobvisika nyore. Asi kuitira kuchengetedza kwekupedzisira mumapombi madiki, hapana chinokunda aChokwadi Unionvharafu. Iyi dhizaini ine nzungu mbiri dzemubatanidzwa dzinokurega iwe uchibvisa zvachose muviri wepakati wevhavha kuti ugadziriswe kana kutsiviwa nepo chinongedzo chinopera chichiramba chakanamira pombi. Ndiwo akanakisa epasirese: kubatana kwakasimba uye nyore sevhisi.

Ndeapi marudzi akasiyana eMOV mavharuvhu?
Iwe unoda kugadzirisa yako system, asi "MOV" inonzwika senge yakaoma maindasitiri michina. Hauna chokwadi nezvesimba sosi, sarudzo dzekudzora, uye kana zvichitoshanda kune yako purojekiti.
MOV inomiriraMotorized Operated Valve, inova chero vharafu inodzorwa neanoridza. Mhando mbiri huru ndeyemagetsi emagetsi, anoshandisa mota yemagetsi, uye pneumatic actuators, iyo inoshandisa mweya wakadzvanywa kuti ushandise vharafu.
MOV haisi mhando yakakosha yevharuvhu; ivharuvhu yakajairika ine actuator yakaiswa pairi. Mhando ye actuator ndiyo yakakosha.Magetsi emagetsindiwo anonyanya kuzivikanwa ePVC bhora mavharuvhu muhurongwa hwemvura. Vanoshandisa mota diki kuvhura vharuvhu kana kuvharika uye inowanikwa mumagetsi akasiyana siyana (se24V DC kana 220V AC) kuti ienderane nekwako magetsi. Iwo akakwana kune zvikumbiro senge otomatiki yekudiridza nzvimbo, mvura yekurapa dosing, kana kure tangi kuzadza.Pneumatic actuatorsshandisa simba remhepo yakadzvanywa kuti uvhure vharafu kana kuvhara nekukurumidza. Iwo ane simba zvakanyanya uye akavimbika asi anoda mhepo compressor uye mitsara yemhepo kuti ishande. Iwe unongodziona chete muzvirimwa zvakakura zveindasitiri uko mweya wakamanikidzwa watove chikamu chezvivakwa. Kune vazhinji vevatengi veBudi, magetsi emagetsi anopa yakaringana yekudzora, mutengo, uye nyore.
Ndeupi musiyano uripo pakati pemhando 1 uye mhando 2 bhora vharafu?
Uri kuverenga pepa uye woona “Type 21 Ball Valve” uye hauzive kuti zvinorevei. Uri kutyira kuti unogona kunge uchishaya ruzivo rwakakosha nezvekuchengetedzwa kwayo kana kuita kwayo.
Iri izwi rinowanzo reva zvizvarwa zvechokwadi mavharuvhu emubatanidzwa kubva kune chaiwo mabhureki. "Type 21" yave shorthand yemazuva ano, yepamusoro-soro dhizaini inosanganisira kuchengetedzwa kwakakosha uye mashandisiro akaita se block-safe union nut.
Mazwi ekuti "Type 1" kana kuti "Type 21" haisi miyero yepasirese kune vese vanogadzira, asi inoreva magadzirirwo ane simba akaumba musika. Funga nezve "Type 21" seinomiririra yazvino, premium mwero wevharuvhu yemubatanidzwa. Patakagadzira mavharuvhu edu echokwadi ePntek, takabatanidza misimboti inoita kuti magadzirirwo aya ave akanaka. Chinhu chinonyanya kukosha ndechekuitaBlock-Safe Union Nut. Iyi ndiyo nzira yekuchengetedza iyo nati ine tambo yekukiya, zvichiita kuti zvisaite netsaona kusunungura nekuvhura sisitimu iri pasi pekumanikidzwa. Izvi zvinodzivirira kuputika kwengozi. Zvimwe zvakajairika zvemhando iyi zvinosanganisirahuviri hunde O-mhetekuitira kudzivirira kudonha kwepamusoro pamubato uye anintegrated mounting pad(kazhinji kune ISO 5211 yakajairwa) izvo zvinoita kuti zvive nyore kuwedzera actuator yemagetsi gare gare. Haisi vharafu chete; chinhu chakachengeteka, chakavimbika, uye mune ramangwana-uchapupu system chikamu.
Mhedziso
Iwo mana makuru mavharuvhu marudzi anoreva chimiro chemuviri, asi kunzwisisa kwechokwadi kunobva pakuziva chiteshi, kubatana, uye sarudzo dzekuita. Ruzivo urwu runoita kuti usarudze vharafu yakakwana kune chero basa.
