Vharuvhu yegedhiimhaka yekuchinja kwemaindasitiri. Kunyangwe mamwe magadzirirwo emavharuvhu, akadai semavharuvhu epasi rose nemavharuvhu eplug, avepo kwenguva yakareba, mavharuvhu egedhi ave nechinzvimbo chikuru muindasitiri kwemakumi emakore, uye nguva pfupi yadarika ndipo pavakapa mugove mukuru wemusika kumagadzirirwo emavharuvhu ebhora nemavharuvhu ebhururu.

Musiyano uripo pakati pevharuvhu regedhi nevharuvhu rebhora, vharuvhu replagi nevharuvhu rebutterfly ndewekuti chinhu chinovhara, chinonzi disc, gate kana occluder, chinokwira pasi petsinde revharuvhu kana spindle, chinobuda munzira yemvura chopinda pamusoro pevharuvhu, chinonzi bonnet, uye chinotenderera nepakati pespindle kana spindle mukutenderera kwakawanda. Mavharuvhu aya anovhurika mukufamba kwakatwasuka anozivikanwawo semavharuvhu akawanda kana kuti linear, kusiyana nemavharuvhu ekota, ane tsinde rinotenderera 90 degrees uye risingawanzo kusimuka.

Mavharuvhu egedhi anowanikwa mumhando dzakasiyana-siyana uye muzviyero zvekumanikidzwa. Ane saizi dzakasiyana kubva kuNPS inokodzera ruoko rwako kubva pahafu yeinchi kusvika kurori hombe yeNPS ine 144 inches. Mavharuvhu egedhi ane ma castings, forgings, kana zvikamu zvakagadzirwa nekuwelding, kunyangwe dhizaini yekukanda iriyo inonyanya kukosha.

Chimwe chezvinhu zvinonyanya kudiwa nemavharuvhu egedhi ndechekuti anogona kuvhurwa zvizere pasina kuvharika kwakanyanya kana kukweshana mumaburi ekuyerera kwemvura. Kudzivirira kuyerera kwemvura kunopiwa nevharuvhu regedhi rakavhurika kwakafanana nekwechikamu chepombi ine saizi yakaenzana yechiteshi. Nokudaro, mavharuvhu egedhi achiri kutariswa zvakanyanya kuti avharidzike kana kuvhurwa/kubviswa. Mune mamwe mazita emavharuvhu, mavharuvhu egedhi anonzi mavharuvhu epasi.

Mavharuvhu egedhi haawanzo kukodzera kudzora kuyerera kwemhepo kana kushanda kune chero divi kunze kwekuvhura zvizere kana kuvhara zvizere. Kushandisa vharuvhu yegedhi yakavhurika zvishoma kudzora kuyerera kwemhepo kunogona kukuvadza ndiro yevharuvhu kana rin'i yechigaro chevharuvhu, nekuti munzvimbo yekuyerera kwemhepo yakavhurika zvishoma inokonzera kusagadzikana, nzvimbo dzechigaro chevharuvhu dzichasangana.

Maitiro evharuvhu yegedhi

Kubva kunze, mavharuvhu mazhinji egedhi akafanana. Zvisinei, kune mikana yakawanda yekugadzira. Mavharuvhu mazhinji egedhi ane muviri nebhoneti, ine chinhu chinovhara chinonzi disc kana gate. Chinhu chinovhara chakabatana netsinde rinopfuura nepabhoneti uye pakupedzisira kune handwheel kana imwe drive kuti ishande tsinde. Kumanikidzwa kwakatenderedza tsinde revharuvhu kunodzorwa nekumanikidzwa kwepakeji munzvimbo yekurongedza kana mukamuri.

Kufamba kweplate yevharuvhu yegedhi padanda revharuvhu kunosarudza kana danda revharuvhu richikwira kana kuskuruwa muplate yevharuvhu panguva yekuvhurwa. Maitiro aya anotsanangurawo maitiro maviri makuru estem/disc emavharuvhu egedhi: danda rinokwira kana danda risingakwire (NRS). danda rinokwira ndiro dhizaini yestem/disc inozivikanwa zvikuru mumusika wemaindasitiri, nepo danda risingakwire rave richifarirwa kwenguva refu neindasitiri yewaterworks nemapaipi. Mamwe mashandisirwo engarava achiri kushandisa mavharuvhu egedhi uye ane nzvimbo diki anoshandisawo maitiro eNRS.

Dhizaini yestem/bhoneti inonyanya kushandiswa pamavharuvhu eindasitiri ndeye external thread and yoke (OS&Y). Dhizaini yeOS&Y inonyanya kukodzera nzvimbo dzinopisa nekuti shinda dziri kunze kwenzvimbo ine chisimbiso chemvura. Yakasiyana nedzimwe dhizaini pakuti handwheel yakabatana nebushing iri pamusoro pejoko, kwete padzinde pacharo, kuitira kuti handwheel isasimuke kana vharuvhu yakavhurika.

Kupatsanurwa kwemusika wevharuvhu yegedhi

Kunyangwe mumakore makumi mashanu apfuura, mavharuvhu anotenderera ekona yekurudyi akatora chikamu chikuru mumusika wemavharuvhu egedhi, mamwe maindasitiri achiri kuvimba nawo zvakanyanya, kusanganisira indasitiri yemafuta negesi. Kunyangwe mavharuvhu ebhora afambira mberi mumapaipi egasi rechisikigo, mavharuvhu emafuta asina kuchena kana emvura achiri kushandiswa mumavharuvhu egedhi agere padivi.

Kana dziri hombe, mavharuvhu egedhi achiri kushandiswa zvakanyanya muindasitiri yekunatsa. Kusimba kwedhizaini uye mutengo wemari yese yekuva muridzi (kusanganisira kuchengetedza mari yekugadzirisa) ndizvo zvinhu zvinodiwa padhizaini iyi yechinyakare.

Panyaya yekushandisa, nzira dzakawanda dzekuchenesa dzinoshandisa tembiricha yakakwira kupfuura tembiricha yakachengeteka yeTeflon, inova ndiyo nzvimbo huru yekuisa mavharuvhu ebhora anoyangarara. Mavharuvhu ebhatafura ane simba guru uye mavharuvhu ebhora akavharirwa nesimbi ari kutanga kushandiswa zvakanyanya mukuchenesa, kunyangwe mutengo wavo wese wekuva muridzi unowanzo kuve wakakwira kupfuura wevharuvhu dzegedhi.

Indasitiri yemvura ichiri kutungamirwa nemavharuvhu esimbi. Kunyangwe kana akavharirwa, akachipa uye anogara kwenguva refu.

Mashandisirwo eindasitiri yemagetsimavharuvhu egedhi re alloypakushandiswa kunosanganisira kumanikidzwa kwakanyanya uye tembiricha yakakwira zvikuru. Kunyangwe mamwe mavharuvhu matsva eY-type globe uye mavharuvhu esimbi akagadzirwa kuti avhare akawanikwa mugwenya remagetsi, mavharuvhu egedhi achiri kufarirwa nevagadziri vefekitori nevashandisi.
