Seimwe yeakakosha mavharuvhu eindasitiri ekurapwa kwemvura mumapaipi,butterfly valvesachatambura madhigirii akasiyana ekupfeka nekuda kwekugara uchishandiswa munzvimbo dzenguva refu uye dzakaoma.Nokudaro, kugadzirisa nguva dzose uye kugadzirisa kunodiwawo.Ingotsiva zvikamu zvinodiwa kuti udzivise kuvharika kwemidziyo kana njodzi dzekuchengetedza dzinokonzerwa nekutadza kwevhavha, iyo inogona kuwedzera kushandiswa kwevhavha uye kuchengetedza mari.
Chii chinogadziriswa pavharuvhu yeshavishavi?Butterfly valve kugadzirisa kugadzirisa kunogona kusiyana zvichienderana nerudzi rwekukuvara kana kukundikana.Inogona kukamurwa kuita kugadzirisa, kugadzirisa kwakawanda uye kugadzirisa kunorema.
- Maintenance inoreva kugadzirisa kwezuva nezuva, uye hapana chikonzero chekuparadzanisa vharuvhu ye butterfly kana kutsiva zvikamu.Semuenzaniso, kana vharuvhu isingashandiswi, mvura yaunganirwa inofanira kudonhedzwa, kukwizwa nguva dzose kunofanira kuitwa, uye vharuvhu yeshavishavi inofanira kuongororwa nguva dzose kana ichibuda.
- Kugadzirisa kwakazara kunoreva kutwasanuka kwevharuvhu, kubatanidza kusimba kwebhaudhi, nezvimwe.
- Kuchengetedza kwakanyanya kunoda kuchinjwa kweplateti yevhavha, zvigaro zvevhavha uye zvimwe zvinhu zvikuru.
Ndezvipi zvikamu zvikuru zvevharuvhu yeshavishavi?
Iwo makuru Zvikamu zve butterfly mavharuvhu anosanganisira:
Muviri.
Disc.
Stem.
Seat.
Actuator.
saka, Sei kugadzirisa butterfly vharafu?
1. Nhanho yekutanga mukugadzirisa ndeyekuona dambudziko rekukanganisa.
Unogadzirisa sei vharafu ye butterfly?Nyatsoongorora valve uye zvikamu zvakapoteredza.Nekungoziva chikonzero chaicho chedambudziko unogona kuribata nemazvo.Semuenzaniso, panogona kuve nekudonha kunokonzerwa nekubatana kwakasununguka.Hapana chikonzero chekubvisa valve uye kutsiva chigaro chevhavha, sekunge pasina chikonzero chekuvhiyiwa kana uine kutonhora.
Leakage - Mabhaudhi akasununguka, zvigaro zvevharuvhu uye zvisimbiso zvinogona kuchembera, zvichikonzera kuvuza uye kukanganisa kugona kuvhara kwevhavha.
Pfeka - Mukati mevharuvhu, disc, dzinde uye zvisimbiso zvinosakara uye kubvaruka nekuda kwekushanda kwakajairwa, zvichikonzera kuderedzwa kwekuita uye kuvuza.
Corrosion - Nekufamba kwenguva, kuenderera mberi kuratidzwa kunzvimbo dzinoparadza kunogona kukonzera kukuvara kwezvinhu
Stuck valve stem - Nekuda kwekupinda kwezvinhu zvekunze, hunde yevharuvhu inogona kumira, zvichiita kuti vharafu isashande zvakanaka.
2. Kana iyo valve ichida chaizvo kuparadzaniswa, zvino tinopfuurira kune danho rechipiri.
Usati waparadzana, ndapota vharavhavhavha yepamusoro-level kudzivirira kuyerera kwemvura uye depressurize system kuti uve nechokwadi chekuchengeteka.Bvisa zvese zvinongedzo kuvhavha uye bvisa magetsi kana pneumatic actuator (kana iripo).Shandisa maturusi akakodzera kusunungura uye kubvisa mabhaudhi kana zvisungo zvinobata mavharuvhu nemapombi panzvimbo.
Chiyeuchidzo chinodziya: Teerera kune kurongeka uye kutungamirwa kwezvikamu zvekubatanidzazve.
3. Tarisa uone kukanganisa:
Mushure mekubvisa vharafu, tarisa kutaridzika kwechikamu chimwe nechimwe kune zviratidzo zvekukuvadzwa, kupera, kana kuora.Tarisa disc, dzinde, chigaro, zvisimbiso uye chero zvimwe zvine hukama zvikamu zvekutsemuka, ngura kana deformation.
Iyo nzira yekubvisa iyo butterfly valve inoratidzwa muvhidhiyo iri pasi apa.
4. Gadzirisa uye shandura zvinhu zvisina kunaka
Kana pane tsvina yakanamatira pakati peplate yevharuvhu nechigaro chevharuvhu, tanga wabvisa tsvina uye ona kana chigaro chevharuvhu chakaremara nekuda kweizvi.
Kana tsinde yevharuvhu yakaremara, inogona kubviswa uye kutwasanudzwa.
Kana chikamu chipi nechipi chikaonekwa kuti chakuvadzwa kana kuti chakasakara zvokusagadzirisika, chinofanira kutsiviwa nechinotsiva chakakodzera.Ita shuwa kuti chinotsiva chikamu chakafanana nechikamu chekutanga.Zvikamu zvakajairika zvingangoda kutsiviwa zvinosanganisira zvisimbiso, madzinde, uye O-mhete.
5. Unganidza zvakare valve
Unganidzazve vharuvhu yeshavishavi munhevedzano yerodhi ye disassembly.Chenesa uye zora zvikamu sezvinodiwa kuti uve nechokwadi chekushanda zvakanaka uye kuiswa chisimbiso kwakakodzera.Simbisa mabhaudhi kana mabhaudhi, chenjerera kuti usawedzere kudzivirira kukuvadza zvikamu zvevharuvhu kana nzvimbo.
6. Muedzo
Mushure mekunge valve yabatanidzwazve, kushanda kunofanirwa kuongororwa kusati kwadzorerwa mubasa.Kutanga, ita bvunzo yekumanikidza wega kuti utarise kushanda kwevhavha uye tarisa kune inodonha kana kusagadzikana.Chengetedza kuvhura nekuvhara vharafu.
7. Kuiswa
Matanho akakodzera ekumisikidza akakosha kuti uwane yakakwana kushanda kwevharuvhu, kuwedzera hupenyu hwevharuvhu, uye kuve nechokwadi chekuchengetedza uye inoshanda mamiriro ekushanda.
mhedziso:
Kugadzirisa abutterfly valveinosanganisira yakarongeka nzira yekuziva, kuparadzanisa, kuongorora, kutsiva, kuunganidzazve uye kuyedza zvikamu kuti zvidzore kushanda kwazvo.Nekutevera nzira dzakaringana uye kutora matanho ekudzivirira, unogona kuve nechokwadi chekushanda kwakavimbika kwevhavhavhavhavha yako mumhando dzakasiyana dzemaindasitiri.Kana iwe usina chokwadi nezve chero chikamu chemaitiro ekugadzirisa, bvunza nyanzvi ine ruzivo kana tarisa kune nhungamiro yemugadziri kune mirairo chaiyo.
