Kusvika pamwero wakati, vharuvhu yepasi rose nevharuvhu yepasi rose zvinogona kunzi zvine hukama hwakawanda. Zvinogona kutaurwa here kuti vharuvhu yepasi rose nevharuvhu yepasi rose zvinogona kusanganiswa? Shanghai Dongbao Valve Manufacturing Co., Ltd. iri pano kuti ikupindurei mubvunzo uyu.

1. Chimiro
Kana nzvimbo yekuisa iri shoma, ndapota teererai sarudzo:
Iyovharuvhu yegedhiinogona kuvharwa zvakasimba nepamusoro pechisimbiso zvichienderana nekumanikidzwa kwepakati, kuitira kuti pasave nekubuda kwemvura. Pakuvhura nekuvhara, vharuvhu nepamusoro pechisimbiso chechigaro chevharuvhu zvinogara zvichisangana uye zvichikwizana, saka pamusoro pechisimbiso zviri nyore kupfeka. Kana vharuvhu yegedhi yava pedyo nekuvhara, musiyano wekumanikidzwa pakati pekumberi nekumashure kwepombi yakakura, izvo zvinoita kuti pamusoro pechisimbiso pave nekunyanya kupfekwa.
Maumbirwo evharuvhu regedhi achave akaomarara kupfuura vharuvhu rekuvhara. Kubva pakuonekwa, vharuvhu regedhi rakareba kupfuura vharuvhu rekuvhara uye vharuvhu rekuvhara rakareba kupfuura vharuvhu regedhi kana paine caliber imwe chete. Pamusoro pezvo, vharuvhu regedhi rinogona kukamurwa kuita tsvimbo yakajeka uye tsvimbo yerima. Vharuvhu rekuvhara haridaro.
2. Nheyo yekushanda
Kana vharuvhu yekudzima yavhurwa uye yavharwa, tsinde rinosimuka, kureva kuti, kana vhiri reruoko ratenderedzwa, vhiri reruoko rinotenderera uye rinosimudzwa pamwe chete netsinde. Vharuvhu yegedhi inotenderera vhiri reruoko kuti tsinde revharuvhu rifambe kumusoro nekudzika, uye nzvimbo yevhiri reruoko inoramba isina kuchinja.
Mwero wekuyerera kwemvura wakasiyana, vharuvhu regedhi rinodiwa kuti rivhurwe zvizere kana kuti rivharwe zvizere, asi vharuvhu rekumisa haridiwi. Vharuvhu rekudzima rine nzira dzakatarwa dzekupinda nekubuda, uye vharuvhu regedhi harina zvinodiwa zvekupinda nekubuda.
Pamusoro pezvo, vharuvhu yegedhi ine mamiriro maviri chete: yakavhurika zvizere kana yakavharwa zvizere, nhanho yekuvhura nekuvhara gedhi yakakura, uye nguva yekuvhura nekuvhara yakareba. Kufamba kwevharuvhu yeplate yevharuvhu yekudzima idiki zvikuru, uye vharuvhu yeplate yevharuvhu yekudzima inogona kumiswa pane imwe nzvimbo panguva yekufamba kwekugadzirisa kuyerera kwemvura. Vharuvhu yegedhi inogona kushandiswa chete pakucheka, uye haina mamwe mabasa.
3. Musiyano wekushanda
Vharuvhu yekudzima inogona kushandiswa kugadzirisa kudzima nekuyerera kwemvura. Kusasimba kwemvura kwevharuvhu yepasi rose kwakakura, uye zvinonetsa kuvhura nekuvhara, asi nekuda kwekuti daro riri pakati pevharuvhu nepamusoro pekuvhara ipfupi, kuvhura nekuvhara ipfupi.
Nekutivharuvhu yegedhiinogona kuvhurwa zvizere chete uye kuvharwa zvizere, kana yavhurwa zvizere, kuramba kwepakati nepakati mugwara remuviri wevharuvhu kunenge kuri zero, saka kuvhurwa nekuvharwa kwevharuvhu yegedhi kuchachengetedza basa zvakanyanya, asi gedhi riri kure nenzvimbo yekuvhara uye nguva yekuvhurwa nekuvharwa yakareba.
4. Kuiswa uye kuyerera
Mhedzisiro yevharuvhu yegedhi kumativi ese maviri yakafanana. Hapana chinodiwa chemirairo yekupinda nekubuda kwemagetsi pakuisa, uye medium inogona kutenderera kumativi ese maviri. Vharuvhu yekudzima inofanira kuiswa zvichienderana negwara remuseve pamuviri wevharuvhu. Panewo chirevo chakajeka nezvegwara rekupinza nekubuda kwevharuvhu yekudzima. Vharuvhu yenyika yangu "Sanhua" inotaura kuti gwara rekuyerera kwevharuvhu yekudzima rinofanira kuva kubva kumusoro kusvika pasi.
Vharuvhu yekudzima iri pasi uye iri pakakwirira. Kubva kunze, zviri pachena kuti pombi haisi pamutsetse wakatsetseka wechikamu chimwe chete. Nzira yekuyerera kwevharuvhu yegedhi iri pamutsetse wakatsetseka. Kurova kwevharuvhu yegedhi kwakakura kupfuura kwevharuvhu yekumisa.
Kubva pamaonero ekudzivirira kuyerera kwemvura, kudzivirira kuyerera kwevharuvhu regedhi kudiki kana rakavhurwa zvizere, uye kudzivirira kuyerera kwevharuvhu rinomira mutoro kwakakura. Kudzivirira kuyerera kwevharuvhu regedhi rakajairika kunenge 0.08~0.12, simba rekuvhura nekuvhara diki, uye medium inogona kuyerera nemativi maviri.
Kudzivirira kuyerera kwemavharuvhu akajairwa ekuvharwa kwakapetwa katatu kusvika kashanu kupfuura mavharuvhu egedhi. Pakuvhura nekuvhara, inoda kumanikidzwa kuvhara kuti ivharwe. Huremu hwevharuvhu yekumisa haibate pamusoro pekuvhara kana yavharwa zvachose, saka kupera kwenzvimbo yekuvhara kudiki kwazvo. Vharuvhu yekumisa inoda kuwedzera actuator nekuda kwesimba guru rekuyerera inofanira kutarisisa nzira yekudzora torque. Kugadziriswa.
Kana vharuvhu yekudzima yaiswa, nzira yacho inogona kupinda kubva pasi pepakati pevharuvhu yopinda kubva kumusoro nenzira mbiri.
Chakanakira chepakati chinopinda kubva pasi pepakati pevharuvhu ndechekuti kurongedza hakuna kumanikidzwa kana vharuvhu yavharwa, izvo zvinogona kuwedzera hupenyu hwekushanda kwekurongedza, uye zvinogona kutsiva kurongedza kana pombi iri pamberi pevharuvhu iri kumanikidzwa.
Dambudziko rekupinda kwepakati kubva pasi pepakati pevharuvhu nderekuti simba rekufambisa vharuvhu rakakura, kanenge ka1.05 ~ 1.08 kupfuura kupinda kwataurwa pamusoro apa, tsinde yevharuvhu inobatwa nesimba guru re axial, uye tsinde yevharuvhu iri nyore kukotama.
Nekuda kwechikonzero ichi, nzira iyo medium inopinda nayo ichibva pasi inowanzo shandiswa chete kuma small-diameter stop valves (pasi peDN50). Kune ma stop valves ari pamusoro peDN200, medium inopinda ichibva kumusoro. Vharuvhu yemagetsi inodzima inowanzo tevedzera nzira iyo medium inopinda nayo ichibva kumusoro.
Dambudziko rekuti nzira inopinda nayo kubva kumusoro rakasiyana nenzira inopinda nayo kubva pasi. Kutaura zvazviri, inogona kuyerera nemativi ese, tichifunga nezvemaonero akasiyana.
5. Chisimbiso
Kuvhara pasi rosevharuvhuchikamu chidiki chetrapezoidal chepakati pevharuvhu (ona chimiro chepakati pevharuvhu kuti uwane rumwe ruzivo). Kana peridhi yevharuvhu yadonha, zvakafanana nekuvhara vharuvhu (kana musiyano wekumanikidzwa uri mukuru, hongu kuvhara hakuna kusimba, asi mhedzisiro yekurwisa kudzoserwa kumashure haina kuipa). Vharuvhu yegedhi yakavharwa parutivi rweplate yegedhi yepakati pevharuvhu, mhedzisiro yekuvhara haina kunaka sevharuvhu yekumisa, uye peridhi yevharuvhu haizovharwi sevharuvhu yekumisa kana peridhi yevharuvhu yadonha.
