Zvigadzirwa
Valve yeBhabhatafurai Yepamusoro-soro
✧ Tsananguro
Vharuvhu yemapuruvheta inoshanda zvakanyanya rudzi rwevharuvhu yakagadzirirwa kushandiswa kwakasimba kunoda kuvharwa kwakavimbika, kugona kudzvanywa zvakanyanya, uye kuvharwa zvakasimba. Mavharuvhu aya anowanzo shandiswa mumaindasitiri akadai semafuta negesi, kugadzirisa makemikari, kugadzira magetsi, uye kugadzirisa mvura, pakati pemamwe. Dzinozivikanwa nekugona kwadzo kudzora kuyerera zvakanaka uye kutsungirira mamiriro ekushanda akaoma. Zvimwe zvinhu zvakakosha zvemavharuvhu emabhatafura ane simba guru zvinosanganisira: Kuvhara Zvakasimba: Mavharuvhu aya akagadzirwa kuderedza kubuda kwemvura uye kupa chisimbiso chakavimbika kunyangwe munzvimbo dzine kumanikidzwa kwakanyanya kana tembiricha yepamusoro. Kuvaka Kwakasimba: Mavharuvhu emabhatafura ane simba guru anowanzo gadzirwa nezvinhu zvinogara kwenguva refu, zvakaita sesimbi isingatsvedzeri kana alloys dzekunze, kuti dzisaparare kana kupwanyika. Kushanda KweTorque Yakaderera: Mavharuvhu emabhatafura ane simba guru akagadzirwa kuti ashande nesimba shoma, zvichibvumira kushanda zvakanaka uye kuderedza kupfeka pazvikamu zvevharuvhu. Dhizaini Yakachengeteka Pamoto: Mamwe mavharuvhu emabhatafura ane simba guru akagadzirwa kuti asvike pazvinodiwa pamoto, zvichipa jira rakawedzerwa rekuchengetedza kana paine njodzi yemoto. Kugona Kudzvanywa Kwakanyanya: Mavharuvhu aya akakodzera mashandisirwo anoda kugona kubata simba zvakanyanya. Pakusarudza vharuvhu yemabhatafura ine simba guru, zvakakosha kufunga nezvezvinhu zvakaita sekushandiswa kwacho, mamiriro ekushanda, kuenderana kwezvinhu, mitemo yeindasitiri, uye kufunga nezvezvakatipoteredza. Saizi yakakodzera uye kusarudzwa kwakakosha kuona kuti vharuvhu inosangana nezvinodiwa zvekushanda kwechinangwa.
✧ Zvinhu Zvinoita Kuti Valve Yebhatafurai Ishande Zvakanaka
Mavharuvhu eButterfly Anoshanda Zvakanaka ane zvigaro zvepolymer zvine hurefu hwenguva yekurarama uye kuramba makemikari zvakanyanya - makemikari mashoma anozivikanwa kuti anokanganisa mapolymers akavakirwa pafluorocarbon, zvichiita kuti zvigadzirwa izvi zvikwezve kushandiswa kwemavharuvhu emaindasitiri. Hunhu hwayo hunopfuura hwerabha kana mamwe mapolymers efluorocarbon maererano nekumanikidzwa, tembiricha uye kuramba kupfeka.
Dhizaini yevharuvhu
Hunde yeHigh Performance Butterfly Valve iri pakati nepakati pamativi maviri. Kubviswa kwekutanga kunobva pakati pevharuvhu, uye kubviswa kwechipiri kunobva pakati pepombi. Izvi zvinoita kuti dhisiki ibve zvachose kubva padhisiki pamadhigirii mashoma ekushanda kubva pachigaro. Tarisa mufananidzo uri pazasi:
Dhizaini yezvigaro
Nezvechigaro, sezvambotaurwa, vharuvhu yakaputirwa nerabha inovharwa nekudzvanywa muruoko rwerabha. Dhizaini yechigaro cheHigh Performance Butterfly Valve G. Mufananidzo uri pazasi unotsanangura kuti zvigaro zvinokanganiswa sei muzviitiko zvitatu:
Mushure mekuungana: kana zvaungana pasina kumanikidzwa
Kana chigaro chacho chakabatana pasina kumanikidzwa, chinofambiswa nepuratifomu yeshavishavi. Izvi zvinobvumira kuvharwa kwemabubble kubva padanho revacuum kusvika padanho repamusoro revharuvhu.
Kumanikidzwa kweAxial:
Chigaro cheG-seat chinoita kuti chisimbiso chive chakasimba sezvo plate yacho ichifamba. Dhizaini yekuisa chigaro inoderedza kufamba kwakanyanya kwechigaro.
Kumanikidzwa padivi rekuisa:
Kumanikidzwa kunotendeudza chigaro mberi, zvichiwedzera simba rekusunga. Kupinza munzvimbo yekukombama kwakagadzirirwa kubvumidza kutenderera kwechigaro. Iyi ndiyo nzira inofarirwa yekukwirisa chigaro.
Chigaro cheHigh Performance Butterfly Valve chine basa rekurangarira. Chigaro chinodzokera kuchimiro chacho chepakutanga mushure mekuiswa. Kugona kwechigaro kudzoreredzwa kunotsanangurwa nekuyera kudzoreredzwa kwechigaro zvachose. Kudzoreredzwa kwechigaro zvishoma zvinoreva kuti chinhu chacho chine ndangariro iri nani - hachiwanzo dzoreredzwa zvachose kana mutoro waiswa. Nekuda kweizvozvo, kuyerwa kushoma kwekudzoreredzwa zvachose zvinoreva kuvandudzwa kwekudzoreredzwa kwechigaro uye kugara kwenguva refu kwechisimbiso. Izvi zvinoreva kuvandudzwa kwekuvharwa pasi pekumanikidzwa uye kupisa. Kushanduka kunokonzerwa nekupisa.
Kurongedza uye kugadzira mabheyaringi ehunde
Pfungwa yekupedzisira yekufananidza ndiyo chisimbiso chinodzivirira kubuda kwekunze kwemvura munzvimbo yehunde.
Sezvamunoona pazasi, mavharuvhu akafukidzwa nerabha ane chisimbiso chesimbi chiri nyore kwazvo, chisingachinjiki. Dhizaini yacho inoshandisa simbi pakati peshaft uye makapu maviri eU-raber kuvhara medium kudzivirira kubuda kwemvura.
Hapana kugadziriswa kunoitwa panzvimbo yakavharwa, zvinoreva kuti kana paine kubuda kwemvura, vharuvhu inofanira kubviswa pamutsetse wogadziriswa kana kutsiviwa. Nzvimbo yepazasi pemugero haina rutsigiro rwemudzi, saka kana zvidimbu zvikafamba kuenda kunzvimbo yepamusoro kana pasi pemugero, torque yekutyaira inokwira, zvichikonzera kuoma kushanda.
Mavharuvhu eButterfly Anoshanda Zvakanaka anoratidzwa pazasi akagadzirwa nekurongedza kunogadziriswa zvizere (shaft seal) kuti ive nechokwadi chekuti inogara kwenguva refu uye hapana kubuda kwekunze. Kana kubuda kwemvura kukaitika nekufamba kwenguva, vharuvhu ine gland rinogadziriswa zvakakwana. Tendeudza rin'i ye nati panguva imwe chete kusvika kubuda kwemvura kwamira.
✧ Mabhenefiti eHigh Performance Butterfly Valve
Munguva yekuvhura nekuvhara vharuvhu yesimbi yakagadzirwa, nekuti kukweshana kuri pakati pedhisiki nepamusoro pekuvhara kwemuviri wevharuvhu kudiki pane kwevharuvhu yegedhi, haipfeki.
Kuvhurika kana kuvharwa kwesimbi yevharuvhu kupfupi, uye ine basa rekucheka rakavimbika, uye nekuda kwekuti shanduko yechigaro chevharuvhu inoenderana nekusvetuka kwedhisiki revharuvhu, yakakodzera kwazvo kugadzirisa mwero wekuyerera. Saka, rudzi urwu rwevharuvhu rwakakodzera zvikuru kuchekwa kana kudzorwa uye kupwanywa.
