Vanhu vazhinji vanoda kuziva nzira yekushanda yevhavha yegedhi yakapfava-yakavharwa kuitira kuti ishandise zviri nani iyi valve.Iyi inotevera nzira yekushanda uye nzira yekubvisa kukanganisa kwevhavha yakavharwa-yakavharwa gedhi:
Kutanga, kuzarura nekuvhara nzira yevhavha, vashandi vakawanda vanowanzoita zvikanganiso pano, vanongoda kuyeuka kuti nzira yekuvhara yevhavha ndeye clockwise.
Chechipiri, kana iyo yakapfava yekuisa chisimbiso gedhi vharuvhu inoshandiswa mupombi system, iyo pneumatic mudziyo mukati mevhavha inoda kushanda kwemaoko, uye vanhu vanofanirwa kushandisa nzira dzemanyorero kuvhura nekuvhara.Kana iri vharafu yakakura-dhayamita, nhamba yenguva dzekuvhura nekuvhara inoda kuchengetwa pakati pe200 ne600 nguva.
Chechitatu, kuvhura uye kuvhara simba kureba kwevhavha yakapfava-yakavharwa gedhi inoda kuchengetedzwa mukati meimwe nhanho, kunyanya kuchengetedza manpower uye kuita kuti munhu mumwe ashande.Kana nhanho yesimba ichipfuura chiyero ichi, vanhu vaviri kusvika vatatu vanodiwa kuti vabudirire kutanga vharuvhu..
Chechina, ukuru hwevhavha hunofanira kuenzaniswa.Paunenge uchiisa vheji, unofanirwa kuterera kune vheji yevhavha yegedhi yakatarisana pasi.
Soft sealing gedhi valvekukanganisa nzira yekubvisa:
1. Kudonha pakurongedzerwa kwevhavha yegedhi rakapfava
(1) Gland yekurongedza yakasununguka zvakanyanya, uye nati yekutsikirira gland yekuisa inogona kusimbiswa zvakaenzana.
(2) Nhamba yekurongedza madenderedzwa haina kukwana, uye kurongedza kunofanira kuwedzerwa.
(3) Kutakura kunokundikana nekuda kwekushandiswa kwenguva refu kana kuchengetedza kusina kunaka.Inofanira kutsiviwa nekutakura kutsva.Paunenge uchitsiva, zvinofanirwa kucherechedzwa kuti majoini ari pakati pemhete imwe neimwe anofanira kuyambutswa uye akazununguka.
2. Pane mukaha pakati peplate regedhi revhavha yegedhi rakapfava uye nzvimbo yekuisa chisimbiso chechigaro chevharuvhu.
(1) Pane tsvina pakati pekuisa chisimbiso, iyo inogona kubviswa nekugeza.
(2) Kana nzvimbo yekuisa chisimbiso ichikanganiswa, inofanira kudzoserwa pasi, uye kana zvichidiwa, inogona kuve yakatarisa uye kugadzirisa.Nzvimbo yekuvhara pasi inofanira kunge yakadzikama, uye kushata kwayo hakufanirwe kunge yakaderera kupfuura 0.4.
3. Iyo inodonha nati pakubatana pakati pemuviri wevharuvhu uye bhoneti yevhavha yegedhi yakapfava haina kusimbiswa zvakasimba kana kusimbiswa zvisina kuenzana, uye inogona kugadziriswa.
(1) Kukuvadzwa (migero yakatwasuka kana mamakisi emugero, nezvimwewo) panzvimbo yekuisa chisimbiso cheflange inofanira kugadziriswa.
(2) Iyo gasket yakakuvadzwa uye inofanira kutsiviwa negasket nyowani.
4. Soft sealing gedhi vharafu stem transmission haichinjiki
(1) Kana kurongedza kwakanyanyisa, sunungura nati pagland yekurongedza zvakanaka.
(2) Nzvimbo yegland yekurongedza haina kururama, kuitira kuti tsinde yevharuvhu yakanamatira, uye nut iri pachikwata chekutakura inofanira kuvharwa zvakaenzana kuti idzorere gland panzvimbo yayo.
(3) Shinda dziri pahunde ne stem nut dzakakuvadzwa uye dzinofanira kubviswa mushure mekutsemuka.
Soft sealing gedhi mavharuvhu anoshandiswa zvakanyanya.Yakapfava yekuisa chisimbiso gedhi vharafu, yeindasitiri vharafu, kuvhura uye kuvhara chikamu cheyakapfava yekuisa chisimbiso gedhi vhavha ndiro gedhi, mafambiro egedhi anoenderana nekwakananga kumvura, vharanda regedhi rinogona kuvhurwa zvizere nekuvharwa zvizere, uye haigone kugadziridzwa kana kutsiviwa.Peti regedhi rine mativi maviri ekuvhara.Nzvimbo mbiri dzekuvharisa dzevharuvhu yegedhi inonyanya kushandiswa inoumba chimiro cheweji.Wedge shape angle inosiyana nemaparameter evharuvhu, kazhinji 50, uye 2°52 kana tembiricha yepakati isiri yakakwirira.
