Varuvhu yegedhi inoreva vharuvhu umo nhengo inovhara (gedhi) inofamba ichienda yakatwasuka yepakati penzira.Ivhavha yegedhi inogona kungoshandiswa kuvhurika zvakakwana uye yakavharwa kuvharika-kuvharika mupombi, uye haigone kushandiswa kugadzirisa uye kupuruzira.Gedhi vharafu imhando yevharuvhu ine huwandu hwakawanda hwekushandisa.Kazhinji, DN50 midziyo yekucheka inosarudzwa kuti ishandiswe, uye dzimwe nguva mavharuvhu emagedhi anoshandiswawo pakucheka-kubvisa michina ine madhayamita madiki.Ivhavha yegedhi inoshandiswa sechidimbu chekucheka, uye kuyerera kwese kwakananga kana yakazarurwa zvakakwana.Panguva ino, kurasikirwa kwekumanikidzwa kwepakati kuduku.Mavharuvhu egedhi anowanzo kukodzera kumamiriro ekushanda asingade kuvhurwa uye kuvharwa kazhinji uye kuchengetedza gedhi rakazaruka kana kuvharwa zvizere.Haina kukodzera kushandiswa semutemo kana throttling.Kune iyo yekumhanya-mhanya inoyerera yepakati, gedhi rinogona kukonzera kuzunguzika kwegedhi kana rakavhurwa zvishoma, uye kuzununguka kunogona kukanganisa nzvimbo yekuisa chisimbiso yegedhi uye chigaro chevhavha, uye kupuruzira kuchaita kuti gedhi riparadzwe ne. pakati.
Kubva pachimiro chechimiro, mutsauko mukuru imhando yechinhu chekuisa chisimbiso chinoshandiswa.Zvinoenderana nechimiro chezvinhu zvekuisa chisimbiso, mavharuvhu egedhi anowanzo kupatsanurwa mumhando dzakasiyana siyana, senge: wedge gedhi vharafu, parallel gedhi vharafu, parallel kaviri gedhi vharafu, wedge kaviri gedhi vharafu, etc. Mafomu anonyanya kushandiswa mavharuvhu egedhi uye parallel gedhi mavharuvhu.
Gedhi rine nzvimbo mbiri dzekuisa chisimbiso.Nzvimbo mbiri dzekuisa chisimbiso dzevharuvhu yegedhi inonyanya kushandiswa inogadzira wedge.Wedge angle inosiyana nevharuvhu paramita, kazhinji 5 madhigirii.Gedhi revhavha yegedhi rejeri rinogona kuitwa rose, rinonzi gedhi rakaoma;inogonawo kugadzirwa gedhi rinogona kuburitsa zvishoma deformation kuti ivandudze manufacturability uye kugadzira kutsauka kwechisimbiso chepamusoro angle panguva yekugadzirisa.Ndiro yacho inonzi ghedhi re elastiki.
Kana gedhi revhavha rakavharwa, nzvimbo yekuisa chisimbiso inogona kungovimba nepakati pekumanikidza kuvhara, ndiko kuti, kuvimba nekumanikidza kwepakati kudzvanya nzvimbo yekuisa chisimbiso chegedhi kune chigaro chevhavha kune rumwe rutivi kuti ive nechokwadi chekuisirwa chisimbiso. chisimbiso chepamusoro, icho chiri kuzvisimbisa.Mazhinji mavharuvhu emagedhi anotora chisimbiso chekumanikidzirwa, ndiko kuti, kana vharuvhu yakavharwa, gedhi rinofanira kumanikidzwa kurwisa chigaro nechisimba chekunze kuti ive nechokwadi chekusimba kwenzvimbo yekuisa chisimbiso.
Ivhavhavha yegedhi yevharuvhu yegedhi inofamba zvakatevedzana nedzinde revharuvhu, inodaidzwa kuti vharanda regedhi rinosimudza (rinonziwo rising stem gedhi vharafu).Kazhinji pane trapezoidal tambo padanda rekusimudza, kuburikidza nenati iri pamusoro pevharuvhu uye gwara regirovha pamuviri wevharuvhu, iyo inotenderera inoshandurwa kuita mutsara kufamba, ndiko kuti, torque yekushanda inoshandurwa kuita basa rekushanda.
Kana iyo valve yakavhurwa, apo kukwidziridzwa kwegedhi kwakaenzana ne1: 1 nguva yevhavhavhavha, nzira yemvura yakavharwa zvachose, asi nzvimbo iyi haigoni kuongororwa panguva yekushanda.Mukushandiswa chaiko, iyo yepamusoro yevhavha stem inoshandiswa sechiratidzo, ndiko kuti, nzvimbo iyo isingagoni kuvhurwa, senzvimbo yayo yakazaruka zvakakwana.Kuti utarise chiitiko chekuvhara nekuda kwekushanduka kwekushisa, kazhinji inovhurwa kunzvimbo yepamusoro, uyezve kudzoka 1/2 ~ 1 kutendeuka, senzvimbo yevhavha yakazara yakazaruka.Nokudaro, nzvimbo yakazaruka yakakwana yevhavha inotarirwa nechinzvimbo chegedhi (kureva, sitiroko).
Nortech ndeimwe yeanotungamira maindasitiri ekugadzira mavharuvhu muChina ane quality certification ISO9001.
