Vavhavha chisimbiso pamusoro kukuvara chikonzero vharafu bhuku butterfly vharafu

Mechanical kukuvadzwa, yekuisa chisimbiso mukuvhura uye kuvhara kweUS kunoburitsa abrasion, bump, kusvina uye kumwe kukuvadza. Pakati pezvikamu zviviri zvekuisa chisimbiso, pasi pekuita kwekushisa kwepamusoro uye kudzvinyirira kukuru, maatomu anopinda mukati meumwe neumwe, zvichiita kuti adhesion phenomenon. Kana nzvimbo mbiri dzekuisa chisimbiso dzichifambisana, kunamatira kunodhonzwa zviri nyore. Kuisa chisimbiso pamusoro roughness yakakwirira, chiitiko ichi chinoitika nyore nyore. Valve mukuvhara maitiro, dhisiki yevharuvhu iri munzira yekudzokera kuchigaro inokuvadza uye kusvina chisimbiso chepamusoro, kuitira kuti chisimbiso chepamusoro chipfeke kana indentation.
Kukukurwa kwepakati ndiyo mhedzisiro yekupfeka, kugezeswa uye cavitation yenzvimbo yekuisa chisimbiso kana iyo yepakati ichishanda. Pane imwe spidhi, zvimedu zvakanaka zviri mukati zvinotyora chisimbiso chepamusoro uye zvinokonzeresa kukuvara kwenzvimbo. Iyo yepamusoro-yekumhanya svikiro ichageza zvakananga nzvimbo yekuisa chisimbiso uye ikonzere kukuvara kwenzvimbo. Kana iyo yepakati yasanganiswa uye yanyungudika zvishoma, bubble rakatsamwa rinoputika uye rinokanganisa nzvimbo yekuvharira, zvichikonzera kukuvara kwenzvimbo. Iko kuchinjika mhedzisiro yekukukurwa kwezvinobudisa nhau uye kukukurwa kwemakemikari kuchapwanya zvine simba nzvimbo yakasungwa.
Electrochemical erosion, kuisa chisimbiso pamusoro pekubatana, kuvhara pamusoro uye kuvharwa kwemuviri uye kuvhara kwevhavha yemuviri uye yepakati yekumisikidza musiyano, oxygen yekusangana mutsauko uye zvimwe zvikonzero, inoburitsa inogona mutsauko, electrochemical erosion, zvichikonzera kuti anode yenzvimbo yekuisa chisimbiso inyura. .
Kemikari kukukurwa kwepakati, iyo yepakati padyo nenzvimbo yekuvharisa kana pasina ikozvino, iyo yepakati inobata zvakananga chikamu chemakemikari nenzvimbo yekuisa chisimbiso, ichibvisa chisimbiso chepamusoro.
Kuiswa kusina kunaka uye kusagadziriswa kwekugadzirisa kunotungamirira kune basa risina kujairika rekuvhara chisimbiso, uye valve inoshanda nechirwere, iyo inokuvadza chisimbiso chekuvhara nguva isati yakwana.
Kukuvadza kunokonzerwa nekusarudza kusina kunaka uye kushandiswa. Basa guru nderokuti vharuvhu haina kusarudzwa maererano nemamiriro ekushanda, uye valve yakagurwa inoshandiswa sevhavha inoputika, iyo inotungamirira kune yakanyanyisa kuvhara chisimbiso uye yakakurumidza kana kuvhara, kuitira kuti chisimbiso chivhare. uye yakasakara.
Kuisa chisimbiso chepamusoro machining mhando yakashata, kunyanya inoratidzwa mukuvharika kwepamusoro kwakakanganiswa senge makatsemuka, porosity uye clamp dhizaini, nekuda kwekuvharika kwewelding uye kupisa kwekugadziriswa kwekutemerwa kusarudzwa kwakashata mukuita kwekuvharidzira welding uye kupisa kupisa uye kutonga, kunokonzerwa ne Yakashata yekuisa chisimbiso chiso chakasimba kuburikidza nepamusoro kana pasi, nekuda kwekusiyana kunokonzerwa nekukanganisa kana kusagadziriswa kwekupisa, sarudza zvinhu zvekuisa chisimbiso pamusoro pekuoma zvisina kuenzana, pasina ngura, Kunyanya nekuti mukuita kwepamusoro kunofuridza pasi simbi kumusoro, dilute chisimbiso. surface alloy composition inokonzerwa ne. Zvechokwadi, kunewo nyaya dzekugadzira.
Zvikonzero zvekuisa chisimbiso kukuvara kwepamusoro zvinogona kupfupikiswa sezvizvi.
Chikonzero chekuisa chisimbiso kukuvadzwa kwepamusoro kukuvara kwevanhu uye kukuvara kwechisikigo. Kukuvadzwa kwekugadzira kunokonzerwa nezvinhu zvakadai sekugadzirwa kwakashata, kugadzirwa kusina kunaka, kusarudzwa kwezvinhu zvisina kunaka, kuiswa kusina kunaka, kushandiswa kusina kunaka uye kusagadzirisa zvakanaka. Kukuvadzwa kwechisikigo ndiko kupera uye kubvaruka kwevhavha pasi pemamiriro ekushanda akajairika, uye kukuvadzwa kunokonzerwa nekukukurwa kusingadzivisiki uye kuputika kwechisimbiso chepamusoro nepakati.
Butterfly vharafu Manual operation valve inoshandiswa nemubato kana gear transmission device, yemagetsi kana pneumatic butterfly valve inofambiswa nemagetsi kana pneumatic device, zvokuti ndiro yeshavishavi inotenderera 90° kuvhura kana kuvhara vharafu. Pamavharuvhu eshavishavi anoshanda nemaoko (kusanganisira vhiri reruoko remudziyo wekutyaira) kana nechipanera, vharuvhu ichavharwa nekutenderedza vhiri reruoko kana chipanera chakatarisana nevhiri reruoko kana chipanera, kunze kwekunge zvatsanangurwa neimwe nzira muchibvumirano chekuraira. Ivhavha inofanira kuchengetwa muimba yakaoma, ine mhepo. Migumo miviri yevharuvhu nzira inofanira kuvharwa. Nguva refu-yakachengetwa mavharuvhu anofanirwa kuongororwa nguva nenguva kuitira tsvina. Kunyanya kukoshesa kunofanira kubhadharwa kucheneswa kwechisimbiso chepamusoro kudzivirira kukanganisa kwechisimbiso chepamusoro.
