Zvikonzero zvekudonha kwemukati kwemavharuvhu ebhora
1) Zvikonzero zvekudonha kwemukati kwevhavha panguva yekuvaka:
① Kufambisa kusina kunaka uye kusimudza kunokonzera kukanganisa kwevhavha, zvichiita kuti mukati mevhavha ibude;② Paaibuda mufekitari, vharuvhu haina kuomeswa uye yakabatwa ne-anti-corrosion mushure mekunge mvura yaiswa, zvichiita kuti chisimbiso chepamusoro chiparadze uye chigadzire kubuda kwemukati;③ Kudzivirirwa kwenzvimbo yekuvaka kwakanga kusiri panzvimbo, uye valve Hapana mahwendefa ebofu akaiswa kumativi ose maviri, uye tsvina yakadai semvura inonaya uye jecha inopinda muchigaro chevharuvhu, zvichikonzera kubuda;④ Panguva yekuisa, hapana girisi inopinzwa muchigaro chevharuvhu, zvichiita kuti tsvina ipinde kumashure kwechigaro chevharuvhu, kana kubuda kwemukati kunokonzerwa nekupisa panguva yewelding;⑤ Valve Haina kuiswa munzvimbo yakazaruka yakakwana, iyo inokonzera kukanganisa bhora.Panguva yekuputika, kana vheji isiri munzvimbo yakazaruka zvakakwana, iyo welding spatter inokonzera kukanganisa kubhora.Kana bhora rine welding spatter richivhurwa nekudzimwa, chigaro chevharuvhu chichawedzera kukuvadzwa, nekudaro Kukonzera kubuda kwemukati;⑥ Welding slag uye zvimwe zvisaririra zvekuvaka zvinokonzeresa makwara panzvimbo yekuisa chisimbiso;⑦ Kusarurama kwemuganho chinzvimbo panguva yekutakura kana kuisirwa kunokonzera kuvuza, kana iyo valve stem drive sleeve kana zvimwe zvishongedzo zvakaunganidzwa pakona isiriyo, vharafu inodonha.
2) Zvikonzero zvekudonha kwemukati kwevhavha panguva yekushanda:
① Chikonzero chinowanzoitika ndechekuti maneja wekushanda haachengetedze vharafu achifunga nezve kudhura kwekugadzirisa mari, kana kushaya sainzi kutonga kwevharuvhu uye nzira dzekuchengetedza kudzivirira kuchengetedza kwekudzivirira kwevhavha, zvichikonzera kutadza kwekutanga kwemidziyo;② Kusashanda zvakanaka kana kushaikwa Kwekuita gadziriso zvinoenderana nemaitiro ekugadzirisa kukonzeresa kudonha kwemukati;③ Panguva yekushanda kwakajairika, zvisaririra zvekuvaka zvinokwenya nzvimbo yekuvharira, zvichikonzera kudonha kwemukati;④ Nguruve isina kunaka inokonzeresa kukuvadzwa kwechisimbiso chepamusoro uye kukonzera kubuda mukati;Chigaro uye bhora zvakavharwa, zvichikonzera kukanganisa kwechisimbiso uye kubuda kwemukati kana valve yakavhurwa uye yakavharwa;⑥ Iyo vheji yevharuvhu haisi panzvimbo, ichikonzera kudonha kwemukati.Chero vharafu yebhora, zvisinei nenzvimbo yakavhurika kana yakavharwa, kazhinji inorerekera 2 ° kusvika 3 °, izvo zvinogona kukonzera kuvuza;⑦ Mavharuvhu mazhinji akakura-dhayamita anogona kukonzera kubuda.Mavharuvhu mazhinji ebhora ane mavharuvhu stem stoppers.Kana zvikashandiswa kwenguva yakareba, ngura, guruva, pendi uye mamwe marara anoungana pakati pehunde yevharuvhu uye chivharo chevhavha chivharo nekuda kwengura nezvimwe zvikonzero.Aya marara anodzivirira valve kubva pakutenderera panzvimbo.Cause leakage - kana vharuvhu yakavigwa, kureba kwechidzitiro chevharuvhu kunoburitsa uye kudonhedza imwe ngura uye tsvina kudzivirira bhora revharuvhu kuti risatenderere panzvimbo, zvichiita kuti vharafu ibude.Kuomesa kana kusunungura bhaudhi yemuganhu kuchaita kuti muganho usave wakarurama, zvichiita kuti mukati mevuza;⑨ Nzvimbo yevharuvhu yemagetsi emagetsi inoiswa kumberi, uye haina kuvharwa panzvimbo, zvichiita kuti mukati mevuza;⑩ Kushaikwa kwekugadzirisa nguva nenguva uye kugadzirisa kuchaita kuti girisi yekuisa chisimbiso iome, Yakaomeswa uye yakaomeswa yekuisa chisimbiso girisi inounganidza kuseri kwechigaro elastic valve, ichitadzisa kufamba kwechigaro chevhavha uye kuita kuti chisimbiso chikundikane.
Iyo yakagadziriswa shaft bhora valve inowanzoshandiswa mumapaipi egasi chaiwo.Iyo general yekuongorora nzira ndeye: shandura vharafu kune yakavhurika zvizere kana yakavharwa zvakazara chinzvimbo, uye tarisa kana paine kuvuza kuburikidza nekubuda kwevhavha yemuviri drain nozzle.Kana ichigona kudirwa zvakachena, chisimbiso chakanaka.Kana pane nguva dzose kudzvinyirira kubuda, zvinogona kuonekwa kuti valve iri kubuda, uye valve inofanira kurapwa zvakakodzera.
Kurapa maitiro ekudonha kwemukati kwegasi bhora vharafu
① Kutanga tarisa muganho wevhavha kuti uone kana mukati mukati mevhavha inogona kugadziriswa nekugadzirisa muganhu.②Baya imwe girizi kutanga kuti uone kana ichigona kumisa kubuda.Panguva ino, kukurumidza kwejekiseni kunofanira kunonoka.Panguva imwecheteyo, cherechedza shanduko yeinongedzo yegeji yekumanikidza painobuda girisi jekiseni pfuti kuti uone kubuda kwemukati kwevhavha.③ Kana kuvuza kusingagone kumiswa, kubuda kwemukati kunogona kukonzerwa nekuomeswa kwegiresi rekuvharisa rakabaiwa padanho rekutanga kana kukuvara kwenzvimbo yekuvharisa.Inokurudzirwa kuisa jekiseni rekuchenesa mvura panguva ino kuchenesa nzvimbo yekuvhara uye chigaro chevhavha yevhavha.Kazhinji, yakanyoroveswa kweinenge hafu yeawa, kana zvichidikanwa, inogona kunyikwa kwemaawa akawanda kana kunyange mazuva mashoma.Zvakanakisisa kuzarura nekuvhara valve inoshanda kakawanda panguva iyi.④ Bayazve jekiseni girisi, vhura uye uvhare vharafu nguva nenguva, uye buritsa tsvina kunze kwegomba rekumashure rechigaro chevharuvhu uye nzvimbo yekuisa chisimbiso.⑤ Tarisa panzvimbo yakavharwa zvakakwana.Kana kuchine kuvuza, jekiseni girisi yakasimbiswa yekuvharisa, uye vhura mhango yevharuvhu kuti ibude, iyo inogona kuunza mutsauko mukuru wekumanikidza uye kubatsira chisimbiso.Kazhinji, nekubaya girisi yakasimbiswa yekuisa chisimbiso Endoleak inogona kubviswa.⑥ Kana pachine kubuda mukati, gadzirisa kana kutsiva valve.
