Mavharuvhu egedhimavharuvhu akachekwa, anowanzoiswa pamapombi ane dhayamita yakakura kupfuura 100mm, kugura kana kubatanidza kuyerera kwepakati mupombi.Nokuti dhisiki imhando yegedhi, inowanzonzi agedhi vharafu.Thegedhi vharafuine zvakanakira kuderera kwekuchinja kushanda uye kushoma kuyerera kuramba.Nekudaro, iyo yekuisa chisimbiso iri nyore kupfeka uye kubuda, iyo yekuvhura sitiroko yakakura, uye kugadzirisa kwakaoma.Thegedhi vharafuhaigoni kushandiswa sevhavha inotonga uye inofanira kunge iri munzvimbo yakazaruka zvakakwana kana yakavharwa zvakakwana.Nheyo yekushanda ndeyekuti: kana iyogedhi vharafuyakavharwa, hunde yevharuvhu inofamba ichidzika zvichidzika zvichienderana nenzvimbo yekuisa chisimbiso chegedhi vharafuuye chisimbiso pamusoro pechigaro chevharuvhu kuti chive chakatsetseka, chakati sandarara uye chinoenderana.Dzinokwana mumwe nemumwe kudzivirira yepakati kuti isayerera, uye vanovimba nepamusoro wedge kuti iwedzere chisimbiso chekuita.Chidimbu chekuvhara chinofamba chichitevedza nzira yakatwasuka yemutsetse wepakati.Kune marudzi akawanda egedhi mavharuvhu, iyo inogona kukamurwa kuita wedge mhando uye parallel mhando zvichienderana nemhando dzadzo.Mhando imwe neimwe yakakamurwa kuva gedhi rimwechete uye gedhi kaviri.
1.2 Chimiro:
The valve body of thegedhi vharafuinotora fomu yekuzvisimbisa.Kubatana pakati pebhoneti nemuviri wevharuvhu ndiko kushandisa kukwira kumusoro kwepakati mukati mevharuvhu kumanikidza kuvharika kwechisimbiso kumanikidzirwa kuzadzisa chinangwa chekuisa chisimbiso.Thegedhi vharafukurongedza kwakavharwa ne-high-pressure asbestos kurongedza netambo yemhangura.
Chimiro chegedhi vharafuinonyanya kuumbwa nemuviri wevharuvhu, chivharo chevharuvhu, furemu, dzinde revharuvhu, madhisiki evharuvhu ekuruboshwe nekurudyi, uye chisimbiso chekurongedza.
2. Kugadzirisa nzira yegedhi vharafu
2.1 Valve disassembly:
2.1.1 Bvisa mabhaudhi epamusoro ebhoneti, sunungura nzungu dzemabhaudhi mana pabhoneti, shandura dzinde nati rinopesana newachi kupatsanura furemu yevharuvhu kubva kumutumbi wevharuvhu, wobva washandisa mudziyo wekusimudza kusimudza. frame down , Iise panzvimbo chaiyo.Iyo stem nut inofanira kubviswa kuti iongororwe.
2.1.2 Bvisa rin'i inochengeta painovhara ring yechina yevharuvhu, wodzvanya pasi bhoneti nemudziyo unokosha kugadzira mukaha pakati pebhoneti nerin'i ine quadruple.Wobva watora mhete yequad muzvikamu.Chekupedzisira, shandisa mudziyo wekusimudza kusimudza chivharo chevharuvhu pamwe chete nedzinde revharuvhu uye vharafu inovhara kunze kwemuviri wevharuvhu.Iise panzvimbo yekuchengetedza, uye teerera kudzivirira kukanganisa kune valve clack joint surface.
2.1.3 Chenesa mukati memuviri wevharuvhu, tarisa nzvimbo yakabatana yechigaro chevharuvhu, uye ona nzira yekugadzirisa.Ivhara vharafu yakaparadzaniswa nekavha yevhavha yakakosha kana chivharo, uye unamatira chisimbiso.
2.1.4 Sunungura mabhaudhi hinge ebhokisi rekuisa pavhavhavhavhavha.Gland yekurongedza inosunungurwa uye dzinde revharuvhu harina kuvharwa.
2.1.5 Bvisa mativi ekumusoro uye ezasi edhisiki frame, tora kuruboshwe uye kurudyi discs, uye chengetedza mukati universal top uye gasket.Edza huwandu hwese hwegasket uye ita rekodhi.
2.2 Kugadziriswa kwezvikamu zvakasiyana zvevhavha:
2.2.1 Nzvimbo yakabatana yegedhi vharafuchigaro chinofanira kugadzika nechigadziro chakakosha chekukuya (pfuti yekukuya, nezvimwewo).Kukuya kunogona kushandisa abrasive jecha kana emery jira.Iyo nzira zvakare kubva kune yakaoma kusvika kune yakanaka, uye pakupedzisira yakakwenenzverwa.
2.2.2 Iyo yakabatana pamusoro pevhavha clack inogona kukuyiwa nemaoko kana nemuchina wekukuya.Kana iyo nzvimbo iine gomba rakadzika kana groove, inogona kutumirwa kune lathe kana grinder ye micro processing, uye inozokwenenzverwa mushure mekuenzanisa kwese.
2.2.3 Chenesa bhoneti uye yekuisa chisimbiso, bvisa ngura netsvina mukati nekunze kwemadziro epacking press ring, kuitira kuti rin'i yekutsikirira igone kuiswa muchikamu chepamusoro chebhoneti, uye zviri nyore kuita. compress chisimbiso kurongedza.
2.2.4 Chenesa kurongedza kwemukati kwevhavha stem stuffing bhokisi, tarisa kana yemukati yekurongedza chigaro mhete haina kusimba, mukaha uripakati pegomba remukati netsvimbo yekucheka inofanira kusangana nezvinodiwa, uye mhete yekunze nemadziro emukati ekupfekedza. bhokisi harifanirwe kuvharwa.
2.2.5 Chenesa ngura pagland yekurongedza nepressure plate, uye nzvimbo yacho inofanira kunge yakachena uye yakachena.Mukaha uri pakati pegomba remukati wegland uye tsvimbo yekucheka inofanira kusangana nezvinodiwa, uye madziro ekunze uye bhokisi rekushongedza rinofanira kunge risina jamu, kana zvisina kudaro kugadziriswa kunofanira kuitwa.
2.2.6 Sunungura mabhaudhi ehinge, tarisa kuti chikamu chakarukwa chakasimba here uye kuti nzungu haina kusimba, inogona kukweshwa zvishoma kumudzi webhaudhi neruoko, uye pini inofanira kuchinjika kuti itenderere.
2.2.7 Chenesa ngura pamusoro pehunde yevharuvhu, tarisa mabhendekete, uye ruramisa kana zvakakodzera.Iyo trapezoidal tambo chikamu chinofanira kunge chakasimba, pasina kutyora uye kukuvadzwa, uye kupfekedzwa nehupfu hwekutungamirira mushure mekuchenesa.
2.2.8 Chenesa quad ring, uye pamusoro panofanira kutsetseka.Ndege haifanire kunge ine maburrs kana kumonereka.
2.2.9 Mabhaudhi ese ekusungirira anofanira kucheneswa, nzungu dzinofanira kunge dzakakwana uye dzakachinjika, uye zvikamu zvakarukwa zvinofanirwa kuputirwa nehupfu yemutobvu.
2.2.10 Chenesa stem nut uye mukati mekutakura:
①Bvisa vharuvha stem nati kiyi nati uye siruu yekumisa yemba, uye sunungura siruu yekiyi nenzira inopesana newachi.
② Bvisa hunde nati uye bearing, disc spring, uye uichenese neparafini.Tarisa uone kana fanicha ichitenderera uye kuti disc chitubu chine mitswe.
③ Chenesa tsinde yevharuvhu, tarisa kana iyo yemukati bushing trapezoidal screw haina kusimba, uye screwing screw negoko inofanira kuva yakasimba uye yakavimbika.Kupfeka kwebhushi kunofanira kusangana nezvinodiwa, kana zvisina kudaro inofanira kutsiviwa.
④ Pfekedza bere nebhota woiisa muhunde nati.Zvitubu zveDisc zvinosanganiswa sezvinodiwa uye zvinounganidzwa zvakare mukutevedzana.Pakupedzisira, ivhare ne lock nut, uye wozoigadzirisa zvakasimba ne screw.
2.3 Gungano regedhi vharafu:
2.3.1 Isai madhisiki ekuruboshwe nekurudyi pane rin'i yekusungirira hunde woagadzirisa nezvisungo zvekumusoro nezasi.Iro mukati mayo inofanira kuiswa kumusoro kwepasi rose, uye kugadzirisa gasket kunofanira kuongororwa maererano nemamiriro ekugadzirisa.
2.3.2 Isai dzinde revharuvhu pamwe chete nevharuvhu disc muchigaro chevharuvhu kuti zviongororwe.Mushure mokunge dhisiki yevhavha uye nzvimbo yekuvhara yechigaro chevhavha yakanyatsobatana, inofanira kuve nechokwadi kuti nzvimbo yekuisa chisimbiso chevhavha disc yakakwirira kudarika chisimbiso chechigaro chevhavha uye inosangana nehutano hunodiwa.Kana zvisina kudaro, inofanira kugadziriswa.Ukobvu hwegasket kumusoro kusvika hwakakodzera, uye anti-return gasket inoshandiswa kuisimbisa kuti irege kudonha.
2.3.3 Geza muviri wevharuvhu, uye pukuta chigaro chevharuvhu nedhisiki.Wobva waisa dzinde revharuvhu uye dhisiki yevharuvhu muchigaro chevharuvhu, uye isa chivharo chevhavha.
2.3.4 Isa sealing packing sezvinodiwa pane yekuzvivharira chikamu chebhoneti.Iyo yekurongedza yakatarwa uye nhamba yekutendeuka inofanira kusangana nemhando yemhando.Chikamu chepamusoro chekutakura chinomanikidzwa zvakasimba nemhete yekumanikidza, uye pakupedzisira yakavharwa neplate yekuvhara.
2.3.5 Unganidza mhete ine quadruple muzvikamu chimwe nechimwe, shandisa reining ring kuikudza kuti isadonha, uye simbisa nati yebhaudhi rekusimudza bhoneti.
2.3.6 Zadza bhokisi revharuvhu rinovharisa nekurongedza sezvinodiwa, isa mukati mekuita gland nepressure plate, woitarisa zvakasimba nekona yehinge.
2.3.7 Isai furemu yebhoneti, tenderedza dzinde repamusoro kuti furemu iwire pamutumbi wevharuvhu, woisunga nemabhaudhi kuti isadonha.
2.3.8 Isai vharafu yemagetsi drive;waya yepamusoro yechikamu chekubatanidza inofanira kusimbiswa kuti irege kudonha, uye nemaoko edza kana iyo flap switch inoshanduka.
