Globe mavharuvhu,gedhi mavharuvhu, butterfly valves, cheki mavharuvhuuyebhora mavharuvhu, etc. Aya mavharuvhu ave akakosha kudzora zvikamu mumapombi akasiyana masisitimu.Mhando yega yega yevharuvhu yakasiyana muchitarisiko, chimiro uye kunyangwe inoshanda chinangwa.Nekudaro, iyo yekumisa vharafu uye iyogedhi vharafuvane zvimwe zvakafanana pakuonekwa, uye zvose zvine basa rekucheka mupombi.Nokudaro, shamwari dzakawanda dzisina kunyanya kushamwaridzana nevhavha dzichavhiringidza maviri.Muchokwadi, kana iwe ukatarisisa, musiyano uripo pakati pevharuvhu yepasi uyegedhi vharafuyakakura chaizvo.
1.Nemaitiro
Kuchenjerera kunofanira kubhadharwa kune kusarudzwa kana nzvimbo yekuisa iri shoma.Thegedhi vharafuinogona 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.Apo iyogedhi vharafuiri pedyo nekuvhara, mutsauko wekumanikidza pakati pemberi nekumashure kwepombi yakakura, izvo zvinoita kuti chisimbiso chepamusoro chipfeke zvakanyanya.
Chimiro chegedhi vharafuichava yakaoma kudarika valve yekuvhara.Kubva pakuonekwa kwemaonero, thegedhi vharafukureba kupfuura vharafu yekuvhara uye vharafu yekuvhara yakareba kupfuura iyogedhi vharafumuchiitiko chemhando imwe chete.Mukuwedzera, thegedhi vharafurakakamurwa kuita aOS&Y dzindeuye aDzinde risingasimuke.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.Thegedhi vharafuinotenderedza vhiri reruoko kuita kuti hunde yevharuvhu iende kumusoro uye pasi, uye nzvimbo yevhiri reruoko inoramba isina kuchinjwa.Kuyerera kweyero kwakasiyana, iyogedhi vharafuinotarisirwa kuvhurika zvizere kana kuvharwa zvizere, asi vharafu yekumisa haidiwi.Ivhavhavha yekuvhara yakatsanangura nzira yekupinza uye yekubuda;thegedhi vharafuhaina inopinza uye yekubuda nzira inodiwa.
Mukuwedzera, thegedhi vharafuine nyika mbiri chete: yakazaruka kana kuvharwa zvakazara, gedhi rekuvhura nekuvhara sitiroko yakakura, uye yekuvhura nekuvhara nguva yakareba.Kufambisa kwevhavha yevhavha yevhavha yevhavha yevhavha yakavharwa yakanyanya kuduku, uye ndiro yevhavha yevhavha yevhavha inogona kumira pane imwe nzvimbo panguva yekufambisa kwekugadzirisa kuyerera.Thegedhi vharafuinogona kushandiswa chete kucheka, uye haina mamwe mabasa.
3.Performance musiyano
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 iyogedhi vharafuinogona kungovhurwa zvizere uye yakavharwa zvizere, kana yavhurwa zvizere, kuyerera kwepakati mukati mevhavha yemuviri chiteshi kunenge zero, saka kuvhurwa nekuvhara kweiyo.gedhi vharafuichave inoponesa zvakanyanya, asi gedhi riri kure nenzvimbo yekuisa chisimbiso uye yekuvhura nekuvhara nguva yakareba.
4.Kuisa 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 yekumisa inoda kuiswa zvakanyatsoenderana negwara rinoratidzwa nemuseve pamutumbi wevhavha.Pane zvakare chirevo chakajeka maererano negwara rekupinda nekubuda kwevhavha yekumisa.Nzira yekuyerera kwevhavha yekumisa inofanira kubva kumusoro kusvika pasi.
Ivhavha yekuvhara yakaderera mukati uye yakakwirira kunze.Kubva kunze, zviri pachena kuti pombi haisi pamutsetse wakatwasuka wechikamu chimwe.Thegedhi vharafunzira yekuyerera iri pamutsetse wakachinjika.Kurohwa kwegedhi vharafuyakakura kupfuura iyo yevhavha yekumisa.
Kubva pakuona kwekuyerera kwekudzivirira, kuyerera kwekudzivirira kwegedhi vharafuidiki kana yakazarurwa zvizere, uye kuyerera kwekudzivirira kwevhavha yekumisa mutoro yakakura.Iyo inoyerera inopikisa coefficient yeyakajairwagedhi vharafuinenge 0.08 ~ 0.12, simba rekuvhura nekuvhara idiki, uye yepakati inogona kuyerera nemativi maviri.Kuyerera kwekupokana kwemavharuvhu akajairwa evhavha ndeye 3-5 nguva iyo yegedhi mavharuvhu(nhamba yeruzhinji: mutariri wepombi).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.
Pane nzira mbiri dzekuisa valve yekuvhara.Imwe ndeyekuti iyo yepakati inogona kupinda kubva pasi pevhavha core.Zvakanakira ndezvokuti kurongedza hakuna kusimbiswa kana vharuvhu yakavharwa, iyo inogona kuwedzera hupenyu hwebasa rekutakura uye inogona kutakura kumanikidza mupombi pamberi pevhavha.Pasi pemamiriro ezvinhu, kurongedza kunofanira kuchinjwa;iyo yakashata ndeyokuti torque yekufambisa yevhavha yakakura, iyo inenge 1 nguva iyo yekuyerera kwepamusoro, simba reaxial pamadziro evhavha yakakura, uye tsinde yevhavha iri nyore kukotama.Nokudaro, nzira iyi inowanzokodzera mavharuvhu madiki-diameter (pazasi peDN50).Kune mavharuvhu ekumisa pamusoro peDN200, yepakati inoyerera ichibva kumusoro.(Ivhavha yemagetsi inovhara kazhinji inotora nzira iyo svikiro inopinda nayo kubva kumusoro.) Kuipa kwenzira iyo svikiro inopinda nayo kubva kumusoro inongopesana nenzira yekupinda nayo kubva pasi.
