Mhedzisiro yeTembiricha uye Kudzvanya PaButterfly Valve Performance
Vatengi vakawanda vanotitumira mibvunzo, uye isu tichavapindura tichivakumbira kuti vape rudzi rwepakati, kupisa kwepakati uye kudzvinyirira, nokuti izvi hazvirevi chete mutengo wevhavhavhavhavhavhavha, asiwo chinhu chinokosha chinokanganisa kushanda kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha yekushanda.Kubata kwavo pavharuvhu ye butterfly yakaoma uye yakazara.
1. Mhedzisiro yeTembiricha paKuita kweButterfly Valve:
1.1.Material Properties
Munzvimbo dzepamusoro-tembiricha, zvinhu zvakaita se butterfly valve body uye tsinde yevharuvhu zvinoda kuve nekupisa kwakanaka kwekupisa, zvikasadaro simba nekuoma kuchakanganiswa.Munzvimbo yakadzika tembiricha, iyo yevhavha yemuviri zvinhu inova brittle.Naizvozvo, zvinhu zvinodzivirira kupisa zvinodzivirira kupisa zvinofanirwa kusarudzirwa nzvimbo dzepamusoro-tembiricha, uye zvinhu zvine kunaka kusingatonhore kusimba zvinofanirwa kusarudzirwa nharaunda dzinopisa.
Chii chinonzi tembiricha yemuviri wevharuvhu yeshavishavi?
Ductile iron butterfly valve: -10 ℃ kusvika 200 ℃
WCB butterfly valve: -29 ℃ kusvika 425 ℃.
SS butterfly valve: -196 ℃ kusvika 800 ℃.
LCB butterfly valve: -46 ℃ kusvika 340 ℃.
1.2.Kuisa Chisimbiso
Kupisa kwepamusoro kunokonzeresa chigaro chevharuvhu yakapfava, mhete yekuisa chisimbiso, nezvimwewo kupfava, kuwedzera uye kukanganisa, kudzikisa chisimbiso mhedzisiro;nepo tembiricha yakaderera inogona kuomesa chisimbiso zvinhu, zvichikonzera kuderera kwekuita chisimbiso.Naizvozvo, kuitira kuti uve nechokwadi chekuisa chisimbiso munzvimbo dzakakwirira kana dzakaderera tembiricha, zvinodikanwa kuti usarudze zvinhu zvekuisa chisimbiso zvinoenderana nepamusoro tembiricha nharaunda.
Kutevera ndiko kupisa kwekushanda kwechigaro chevharuvhu yakapfava.
• EPDM -46℃ - 135℃ Anti-kuchembera
• NBR -23 ℃-93 ℃ Mafuta Inoramba
• PTFE -20℃-180℃ Anti-corrosion uye makemikari media
• VITON -23 ℃ - 200 ℃ Anti-corrosion, kupisa kwakanyanya
• Silika -55 ℃ -180 ℃ High tembiricha kuramba
• NR -20 ℃ - 85 ℃ High elasticity
• CR -29℃ – 99℃ isingapfeki, inodzivirira kuchembera
1.3.Simba rekuvaka
Ndinotenda munhu wese akanzwa nezve pfungwa inonzi "thermal expansion and contraction".Kuchinja kwekushisa kunokonzeresa deformation yekushushikana kwekushisa kana kutsemuka mumajoini evharuvhu, mabhaudhi uye zvimwe zvikamu.Naizvozvo, kana uchigadzira uye nekuisa butterfly mavharuvhu, zvinofanirwa kutarisisa kukanganisa kwekushanduka kwekushisa pane chimiro chevhavhavhavhavha, uye kutora matanho anoenderana kuderedza kukanganiswa kwekuwedzera kwekupisa uye kuderera.
1.4.Kuchinja kwemaitiro ekuyerera
Kuchinja kwekushisa kunogona kukanganisa kuwanda uye viscosity yemvura inoyerera, nokudaro ichikanganisa kuyerera kwevhavhavhavhavhavha.Mumashandisirwo anoshanda, kukanganiswa kwekushanduka kwekushisa pamaitiro ekuyerera kunoda kutariswa kuti ive nechokwadi chekuti vhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha zwa ṱanganedza zwine zwa vhea zwine zwa vhuya vhukati ha zwine zwavhuḓi.
2. Mhedzisiro yeDzvinyiriro paButterfly Valve Performance
2.1.Kuita chisimbiso
Kana kudzvinyirirwa kwesvikiro remvura kuchiwedzera, vharafu yeshavishavi inoda kukurira musiyano mukuru wekumanikidza.Munzvimbo dzepamusoro-soro, mavharuvhu e butterfly anofanirwa kunge aine chisimbiso chakakwana kuti ave nechokwadi chekuti kuvuza hakuitike kana vharuvhu yakavharwa.Naizvozvo, iyo yekuvharisa pamusoro pevhavhavhavhavha inogadzirwa kazhinji ne carbide uye simbi isina tsvina kuti ive nechokwadi chekusimba uye kupfeka kupikisa kwenzvimbo yekuisa chisimbiso.
2.2.Simba rekuvaka
Butterfly valve Munzvimbo ine simba guru, butterfly valve inoda kumira zvakanyanya, saka zvinhu uye maitiro evhavhavhavhavhavha zvinofanira kuva nesimba rakakwana uye rigidity.Chimiro chevhavhavhavhavha chinowanzobatanidza muviri wevharuvhu, ndiro yevharuvhu, hunde yevharuvhu, chigaro chevharuvhu uye zvimwe zvikamu.Kusakwana kwesimba rechimwe chezvikamu izvi kunogona kuita kuti vharuvhu yeshavishavi ikunde pasi pekumanikidzwa kwakanyanya.Naizvozvo, zvinodikanwa kufunga nezve pesvedzero yekumanikidza paunenge uchigadzira iyo butterfly valve chimiro uye kutora zvine musoro zvinhu uye maumbirwo mafomu.
2.3.Kushanda kwevharuvhu
Iyo yakanyanya-kudzvanywa nharaunda inogona kukanganisa torque yevhavhavhavhavha, uye butterfly vharuvhu ingada simba rekushanda rakakura kuvhura kana kuvhara.Saka, kana butterfly valve iri pasi pekumanikidzwa kwakanyanya, zviri nani kusarudza magetsi, pneumatic uye mamwe maitiro.
2.4.Ngozi yekudonha
Munzvimbo dzepamusoro-soro, njodzi yekudonha inowedzera.Kunyangwe kudonha kudiki kunogona kutungamirira kune kutambisa simba uye njodzi dzekuchengetedza.Naizvozvo, zvinodikanwa kuve nechokwadi chekuti butterfly valve ine yakanaka yekuisa chisimbiso munzvimbo dzakanyanya-kudzvanywa kuti kuderedze njodzi yekudonha.
2.5.Kuramba kuyerera kwepakati
Kuyerera kupikisa chiratidzo chakakosha chekushanda kwevharuvhu.Chii chinonzi flow resistance?Rinoreva kushorwa kunosangana nemvura inopfuura nemuvharuvhu.Iri pasi pekumanikidzwa kukuru, kudzvanywa kwepakati pavharuvhu yeplate kunowedzera, zvinoda kuti shavishavi yevhavha ive nepamusoro pekuyerera.Panguva ino, butterfly valve inoda kuvandudza kuyerera kwekuita uye kuderedza kuyerera kwekudzivirira.
Kazhinji, kukanganisa kwekushisa uye kumanikidzika pakushanda kwevhavhavhavhavhavhavha kune zvakawanda, kusanganisira kuvhara kushanda, simba rekugadzirisa, butterfly valve operation, etc. Kuti uone kuti butterfly valve inogona kushanda kazhinji pasi pemamiriro akasiyana ekushanda, zvakakosha kusarudza. zvinhu zvakakodzera, dhizaini yekugadzira uye kuiswa chisimbiso, uye kutora matanho anoenderana kutarisana nekuchinja kwekushisa uye kumanikidza.
