Valve yeBhabhatafurai Yepamusoro-soro
✧ Tsananguro
Vharuvhu yedu yeButterfly inoshanda zvakanaka ivharuvhu ine simba rekuita double-offset (double eccentric) quarter-turn yakagadzirirwa kushanda zvakanaka pakuvhara nekudzima. Inoita kuti shutoff isashande zvakanaka, ine torque shoma, uye inogara kwenguva refu - imwe nzira inodhura pane mavharuvhu ebhora kana eplug.
Semugadziri wemavharuvhu emabhatafura ane hunyanzvi, tinopa saizi dzinobva pa2″ kusvika 48″ (DN50–DN1200), makirasi ekumanikidza 150, 300, uye 600, newafer, lug, kana flanged connections.
✧ Sei Uchifanira Kusarudza Vharuvhu Iri Rinoshanda Zvakanyanya?
•Dhizaini yekubvisa kaviri– Dhisiki inosimudza chigaro mukati me7°, ichideredza kusakara uye inoderedza torque.
•Kuisa chisimbiso kumativi maviri– Zvigaro zvePTFE, RTFE, kana zvesimbi zvinoita kuti pasave nekubuda kwemvura (Kirasi VI).

Cherechedza:
1. Kana uchida Class 300, simbi isina ngura, kana mavharuvhu anoshandiswa, kumbira mutengo wakagadzirwa newe.
2. Mutengo wemavharuvhu eButterfly anoshanda zvakanaka uri pamusoro apa uchachinjwa zvichienderana nemitengo yezvinhu zvakagadziriswa uye huwandu hweodha.Bata Chikwata Chedu Chekutengesakuti mitengo yacho ive chaiyo.
✧ Sei Uchifanira Kutenga Kubva Kwatiri? – Mugadziri Akavimbika
•Hunhu hwakasimbiswa - API 598 hydrostatic uye chigaro chekuongorora, kurongeka kwezvinhu.
•Mutengo wemakwikwi - Mitengo yefekitori yakananga isina vamiririri.
•Kugadzirisa - OEM/ODM inowanikwa kune zvinhu zvakakosha uye kushanda.
•Kutumirwa kwenyika dzese - Nguva dzekutungamira nekukurumidza uye rutsigiro rwekutengeswa mushure mekutengesa.
✧ Basa reKutengesa Mushure meKutengeswa
Semugadziri wesimbi yakagadzirwa nehunyanzvi uye mutengesi kunze kwenyika, tinovimbisa kupa vatengi basa repamusoro-soro mushure mekutengesa, kusanganisira zvinotevera:
1. Ipai nhungamiro yekushandiswa kwechigadzirwa uye mazano ekugadzirisa.
2. Kana paine kutadza kunokonzerwa nematambudziko emhando yezvigadzirwa, tinovimbisa kupa rutsigiro rwehunyanzvi nekugadzirisa matambudziko munguva pfupi iri kutevera.
3. Kunze kwekukuvadzwa kunokonzerwa nekushandiswa kwakajairika, tinopa mabasa ekugadzirisa nekutsiva mahara.
4. Tinovimbisa kupindura nekukurumidza kune zvinodiwa nevatengi munguva yewarandi yechigadzirwa.
5. Tinopa rubatsiro rwehunyanzvi kwenguva refu, mazano epamhepo uye masevhisi ekudzidzisa. Chinangwa chedu ndechekupa vatengi ruzivo rwakanakisisa rwebasa uye kuita kuti ruzivo rwevatengi ruve nyore uye runonakidza.
✧ Tora Mutengo Nhasi
✧ Ruzivo rwemavharuvhu eshavishavi anoshanda zvakanyanya - Chikwata cheNSW Valve Engineer
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 yeValvu Yakanyanya Kushanda
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:
• Kugadzira Chigaro Chevharuvhu
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:
1. Mushure mekuunganidza:
Kana chigaro chacho chakabatana pasina kumanikidzwa, chinofambiswa nepuratifomu yeshavishavi. Izvi zvinobvumira kuvharwa kwemabubble kubva padanho revacuum kusvika padanho repamusoro revharuvhu.
2. Kumanikidzwa kweAxial:
Chigaro cheG-seat chinoita kuti chisimbiso chive chakasimba sezvo plate yacho ichifamba. Dhizaini yekuisa chigaro inoderedza kufamba kwakanyanya kwechigaro.
3. Kudzvanywa padivi rekuisa:
Kumanikidzwa kunotendeudza chigaro mberi, zvichiwedzera simba rekuvhara. Kuisa munzvimbo yekukombama kwakagadzirirwa kubvumidza kutenderera kwechigaro. Iyi ndiyo nzira inofarirwa yekukwirisa. Chigaro cheHigh Performance Butterfly Valve chine basa rekurangarira. Chigaro chinodzokera kuchimiro chacho chepakutanga mushure mekuiswa. Kugona kwechigaro kudzoreredzwa kunotsanangurwa nekuyera kwekushanduka kwechigarire kwechigaro. Kushanduka kwechigarire kwakaderera zvinoreva kuti chinhu chacho chine ndangariro iri nani - hachiwanzo kushanduka zvachose kana mutoro waiswa. Nekuda kweizvozvo, kuyerwa kwekushanduka kushoma kwechigarire 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 ane rabha ane chisimbiso chesimbi chiri nyore kwazvo, chisingachinjiki. Dhizaini yacho inoshandisa stem bushing pakati peshaft uye maU-cups maviri erabha 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 peshaft haina rutsigiro rwesimbi, saka kana zvidimbu zvikafamba kuenda kunzvimbo yepamusoro kana pasi peshaft, drive torque 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.
