1. Low fluid resistance.
2. Simba rekunze rinodiwa pakuvhura nekuvhara idiki.
3. Nzira yekuyerera kwepakati haina kusungwa.
4. Kana yakazaruka zvakakwana, kukukurwa kwechisimbiso chepamusoro nepakati pekushanda kuduku kudarika kwevhavha yekumisa.
5. Kuenzanisa kwechimiro kuri nyore, uye teknolojia yekukanda yakanaka.
Kuipa kwevhavha yegedhi
1. Kureba kwese uye kureba kwekuvhura kwakakura.Iyo midziyo inoda nzvimbo yakakura.
2. Muchigadziro chekuzarura nekuvhara, pane kupesana kwakasiyana pakati pezvisimbiso zvekuvhara, izvo zvishoma zvinokonzera kutanga.
3. Mavharuvhu emagedhi anowanzo ane zvisimbiso zviviri zvekuvhara, izvo zvinowedzera mamwe matambudziko ekugadzirisa, kugaya nekugadzirisa.
Mhando dzemavhavha emagedhi
1. Inogona kukamurwa maererano nekuronga kwegondohwe
1) Parallel gedhi vharuvhu: nzvimbo yekuisa chisimbiso inoenderana neiyo vertical base mutsara, kureva kuti, nzvimbo mbiri dzekuisa chisimbiso dzakafanana kune imwe neimwe.
Pakati pemavharuvhu egedhi anoenderana, kuronga ne thrust wedge kunowedzera.Kune kaviri-mativi thrust wedge pazasi pemavharuvhu maviri egedhi.Rudzi urwu rwevharuvhu yegedhi yakakodzera kune yakaderera-kudzvanywa kwepakati uye diki dhayamita (dn40-300mm) gedhi mavharuvhu.Panewo zvitubu pakati pemakondohwe maviri, anogona kushandisa simba rekusimbisa, rinobatsira pakunamwa kwegondohwe.
2) Wedge gedhi vharuvhu: nzvimbo yekuvharisa inoumba kona ine vertical base line, kureva kuti, nzvimbo mbiri dzekuisa chisimbiso dzinogadzira vharafu regedhi rakaita seweji.Iyo yakarerekera kona yenzvimbo yekuisa chisimbiso inowanzo 2 ° 52 ', 3 ° 30′, 5 °, 8 °, 10 °, nezvimwewo saizi yekona inonyanya kuenderana neconcave convex yepakati tembiricha.Kazhinji, kukwirisa tembiricha yekushanda, hombe yacho inofanirwa kunge iri, kuitira kuderedza mukana wekuroora kana tembiricha yachinjwa.Muwedge gedhi vharafu, kune imwe gedhi vharafu, kaviri gedhi vharafu uye elastic gedhi vharafu.Iyo imwe gedhi wedge gedhi valve ine kuronga kuri nyore uye kushanda kwakavimbika, asi inoda kurongeka kwepamusoro kwekona yenzvimbo yekuisa chisimbiso, iyo yakaoma kugadzirisa nekugadzirisa, uye inogona kubatanidzwa kana tembiricha yachinjwa.Double gedhi wedge gedhi mavharuvhu anoshandiswa zvakanyanya mumvura uye nemhepo yepakati mapaipi.Mabhenefiti ayo ndeaya: kurongeka kwemakona echisimbiso chepamusoro chinoda kuve chakaderera, uye kushanduka kwekushisa hakusi nyore kukonzera chiitiko chemuchato.Kana nzvimbo yekuisa chisimbiso ichipfekwa, inogona kukwizwa kuitira muripo.Nekudaro, rudzi urwu rwekuronga rune zvikamu zvakawanda, izvo zviri nyore kusungirira mu viscous medium uye zvinokanganisa kuiswa chisimbiso.Zvinonyanya kukosha, mabheti ekumusoro uye ezasi ari nyore kuita ngura mushure mekushandisa kwenguva refu, uye gondohwe riri nyore kudonha.Elastic gedhi wedge gedhi vharafu, ine kurongeka kuri nyore kwekamwe gedhi wedge gedhi vharafu, inogona kuburitsa diki diki deformation yekubhadhara kutsauka mukugadziriswa kwekona yekuisa chisimbiso uye kugadzirisa hunyanzvi nekushandisa * mabhenefiti, uye ane yakasarudzwa nevakawanda.
2. Maererano nekuronga kwevhavha stem, gedhi regedhi rinogona kugoverwa mukati
1) Rising stem gedhi vharafu: iyo valve stem nati iri pachivharo chevharuvhu kana tsigiro.Pakuvhura nekuvhara gedhi, tenderedza hunde revharuvhu kuti upedze kusimudza dzinde revharuvhu.Rudzi urwu rwekuronga runobatsira pakuzora simbi yevharuvhu, uye dhigirii rekuvhura nekuvhara riri pachena, saka rinoshandiswa zvakanyanya.
2) Isingasimuke dzinde regedhi vharafu: iyo valve stem nati iri mumuviri wevharuvhu uye inobata zvakananga pakati.Paunenge uchivhura nekuvhara gondohwe, tenderera tsvimbo yevharuvhu.Kubatsira kwechirongwa ichi ndechekuti kureba kwevhavha yegedhi nguva dzose inoramba isingachinji, saka nzvimbo yemidziyo idiki.Inokodzera gedhi mavharuvhu ane dhayamita hombe kana kumanikidzirwa midziyo nzvimbo.Kuronga kwakadai kuchave nezviratidzo zvekuvhura nekuvhara kuratidza dhigirii rekuvhura nekuvhara.Kukanganisa kwechirongwa ichi ndechekuti tambo yehunde haingokwanisi kuomeswa, asiwo yakananga kunyungudika nepakati uye kukuvara zvishoma.
Iyo dhayamita yevhavha yegedhi inopfupiswa
Tichifunga kuti dhayamita yechiteshi mumutumbi wevharuvhu yakasiyana (kazhinji dhayamita pachigaro chevharuvhu idiki pane iri pakubatana kweflange), inonzi kupfupisa nzira.
Kudzikisa dhayamita yekukukurwa kunogona kuderedza saizi yezvikamu uye simba rinodiwa pakuvhura nekuvhara.Pamwe chete, inogona kuwedzera kuronga kwekushandisa kwezvikamu.
Mushure mekudzikisa dhayamita yekudonha.Kuramba kwemvura kunowedzera.
