Kusvika kumwero wakati, vharuvhu yepasi uye vheji yegedhi zvinogona kunzi zvine zvakawanda zvinongedzo.Zvinogona here kutaurwa kuti vheji yepasi uye gedhi regedhi rinogona kusanganiswa?Shanghai Dongbao Valve Manufacturing Co., Ltd. yauya kuzokupindura mubvunzo uyu.

1. Chimiro
Kana nzvimbo yekuisa ishoma, ndapota teerera kune kusarudzwa:
Thevharafu yegedhiinogona kuvharwa zvakasimba nechiso chekuvhara zvichienderana nekumanikidzwa kwepakati, kuitira kuti uwane mhedzisiro yekusadonha.Paunenge uchivhura nekuvhara, iyo yevhavha yepakati uye chigaro chevhavha chisimbiso chepamusoro chinogara chakabatana uye chichikwizana kune mumwe nemumwe, saka chisimbiso chepamusoro chiri nyore kupfeka.Kana gedhi revhavha rave pedyo nekuvhara, mutsauko wekumanikidza pakati pemberi nekumashure kwepombi yakakura, izvo zvinoita kuti chisimbiso chepamusoro chipfeke zvakanyanya.
Chimiro chevhavha yegedhi chichave chakaoma kupfuura chivharo chekuvhara.Kubva pakuonekwa kwemaonero, gedhi regedhi rakareba kudarika vheji yekuvhara uye kuvhara kwevhavha yakareba kudarika gedhi regedhi munyaya ye caliber yakafanana.Mukuwedzera, valve yegedhi inogona kugoverwa kuva tsvimbo yakajeka uye tsvimbo yakasviba.Ivhavha yekuvhara haiiti.
2. Kushanda musimboti
Apo vhavha yekuvhara yakavhurwa uye yakavharwa, tsinde inosimuka, kureva kuti, kana gumbo remaoko richishandurwa, gumbo remaoko richatenderera uye rinosimudza pamwe chete nehutu.Ivhavhavha yegedhi inotenderera vhiri reruoko kuita kuti hunde yevharuvhu iende kumusoro uye pasi, uye nzvimbo yevhiri remaoko inoramba isina kuchinja.
Chiyero chekuyerera chakasiyana, gedhi regedhi rinodiwa kuti rive rakazaruka zvakakwana kana rakavharwa zvakakwana, asi kuvhara kwevhavha hakudiwi.Ivhavha yekuvhara yakatsanangura nzira yekupinza uye yekubuda, uye vheji yegedhi haina inopinza uye yekubuda nzira inodiwa.
Mukuwedzera, gedhi regedhi rine nyika mbiri chete: yakazaruka zvakakwana kana yakavharwa zvakakwana, gedhi rekuzarura nekuvhara sitiroko yakakura, uye nguva yekuzarura nekuvhara yakareba.Kufambisa kwevhavha yevhavha yevhavha yevhavha yevhavha yakavharwa yakanyanya kuduku, uye ndiro yevhavha yevhavha yevhavha inogona kumira pane imwe nzvimbo panguva yekufambisa kwekugadzirisa kuyerera.Ivhavha yegedhi inogona kungoshandiswa pakucheka, uye haina mamwe mabasa.
3. Kusiyana kwekuita
Ivhavha yekuvhara-vhavha inogona kushandiswa pakucheka uye kugadzirisa kuyerera.Kupikiswa kwemvura yevharuvhu yeglobe yakakura, uye zvinonetsa kuvhura nekuvhara, asi nekuda kwekuti chinhambwe chiri pakati peplate yevharuvhu nenzvimbo yekuvharisa ipfupi, kuvhura nekuvhara sitiroko ipfupi.
Nokuti iyovharafu yegedhiinogona chete kuvhurwa zvizere uye kuvharwa zvizere, kana yanyatsovhurwa, kuyerera kwepakati kuyerera mumugero wemuviri wevharuvhu kunenge zero, saka kuvhurwa nekuvhara kwevhavha yegedhi kuchave kuponesa basa, asi gedhi riri kure. kubva pachisimbiso chepamusoro uye nguva yekuzarura nekuvhara yakareba..
4. Kuiswa uye kuyerera
Mhedzisiro yevhavha yegedhi mumativi ese ari maviri akafanana.Iko hakuna chinodiwa kune inopinza uye yekubuda nzira yekuisirwa, uye yepakati inogona kutenderera mumativi ese.Ivhavha yekuvhara inoda kuiswa zvakanyatsoenderana nekutungamira kwechiratidzo chemuseve pamutumbi wevhavha.Panewo chirevo chakajeka pamusoro pekutungamira kwekupinda uye kubuda kwevhavha yekuvhara.vharuvhu yenyika yangu "Sanhua" inotsanangura kuti mafambiro evharuvhu yekuvhara anofanira kubva kumusoro kusvika pasi.
Ivhavha yekuvhara yakaderera mukati uye yakakwirira kunze.Kubva kunze, zviri pachena kuti pombi haisi pamutsetse wakatwasuka wechikamu chimwe.Nzira yekuyerera yegedhi iri pamutsetse wakachinjika.Kurova kwevhavha yegedhi yakakura kudarika iyo yevhavha yekumira.
Kubva pamaonero ekudzivirira kuyerera, kuyerera kwevhavha yegedhi idiki kana yakazarurwa zvakakwana, uye kuyerera kwekudzivirira kwevhavha yekumisa mutoro yakakura.Iyo inoyerera inopikisa coefficient yeyakajairwa gedhi vharuvhu inenge 0.08 ~ 0.12, kuvhura uye kuvhara simba idiki, uye yepakati inogona kuyerera munzira mbiri.
Kuyerera kwekupokana kweakajairwa-kuvhara mavharuvhu ndeye 3-5 nguva iyo yegedhi mavharuvhu.Pakuvhura nekuvhara, inoda kumanikidzwa kuvhara kuti iwane chisimbiso.Ivhavha yevhavha yevhavha yekumira haibatanidzi nzvimbo yekuvhara kana yakavharwa zvachose, saka kupfeka kwechisimbiso kuduku zvikuru.Iyo yekumisa vharafu inoda kuwedzera actuator nekuda kweiyo huru yekuyerera simba inofanirwa kutarisisa kune torque control mechanism Adjustment.
Kana iyo yevhavha yekuvhara yakaiswa, iyo yepakati inogona kupinda kubva pasi pevhavha yepakati uye kupinda kubva kumusoro nenzira mbiri.
Kubatsira kwepakati inopinda kubva pasi pevhavha yepakati ndeyokuti kurongedza hakusi pasi pekumanikidzwa kana valve yakavharwa, iyo inogona kuwedzera hupenyu hwebasa rekutakura, uye inogona kutsiva kurongedza apo pombi iri pamberi pevhavha iri pasi. pressure.
Kuipa kwepakati inopinda kubva pasi pevhavha yepakati ndeyokuti torque yekufambisa yevhavha yakakura, inenge 1.05 ~ 1.08 nguva iyo iri pamusoro inopinda, tsinde yevhavha inoiswa pasi pesimba guru re axial, uye tsinde yevhavha. iri nyore kukotama.
Nechikonzero ichi, nzira iyo svikiro inopinda nayo kubva pazasi inowanzokodzera madiki-diameter yekumisa mavharuvhu (pazasi peDN50).Kune mavharuvhu ekumisa pamusoro peDN200, iyo yepakati inopinda kubva kumusoro.Ivhavhavha yekuvhara yemagetsi inowanzotora nzira iyo yepakati inopinda nayo kubva kumusoro.
Kuipa kwenzira inopinda nesvikiro kubva kumusoro kunongopesana nenzira inopinda nayo svikiro kubva pasi.Muchokwadi, inogona kuyerera munzira mbiri, uchingofunga nezvemaonero akasiyana.
5. Chisimbiso
Chisimbiso pamusoro pepasivharafuidiki trapezoidal divi revhavha core (ona chimiro chevhavha core kuti uwane ruzivo).Kana imwe nguva yevhavha inowira pasi, yakaenzana nekuvhara valve (kana mutsauko wekumanikidzika wakakura, chokwadi kuvhara hakusi kuoma, asi anti-reverse effect haina kuipa).Ivhavha yegedhi yakavharwa nedivi revhavha yepakati peplate yegedhi, iyo yekuisa chisimbiso haina kunaka sevhavha yekumisa, uye iyo yevhavha yepakati haizovharwe sevhavha yekumisa kana simbi yevhavha ichidonha.
