Gedhi vharafuchibereko chekuchinja kwemaindasitiri. Kunyangwe mamwe madhizaini evharuvhu, akadai semavharuvhu epasi uye mavharuvhu epuragi, avepo kwenguva yakareba, mavharuvhu emagedhi akagara pachinzvimbo chepamusoro muindasitiri kwemakumi emakore, uye nguva pfupi yadarika vakasiya chikamu chikuru chemusika kune mavharuvhu ebhora uye butterfly valve dhizaini. .

Musiyano uripo pakati pevharuvhu yegedhi nevharuvhu yebhora, plug vharafu uye butterfly vharafu ndewekuti chinhu chinovhara, chinonzi disc, gedhi kana occluder, chinosimuka pazasi pechidzitiro chevharuvhu kana chinorukwa, chinosiya nzira yemvura uye chopinda pamusoro pevharuvhu, inonzi bonnet, uye inotenderera nemuchinorukwa kana kuti chinorukwa mumichinjiko yakawanda. Aya mavharuvhu anovhura mukufamba kwemutsara anozivikanwawo semavharuvhu akawanda anotenderera kana mutsara, kusiyana nemavharuvhu ekota, ane dzinde rinotenderera 90 madhigirii uye asingawanzo kusimuka.

Mavharuvhu egedhi anowanikwa mune akawanda ezvigadzirwa zvakasiyana uye kudzvanywa ratings. Iwo anosiyana muhukuru kubva kuNPS inokodzera ruoko rwako ½ Inch kusvika kurori hombe NPS 144 inch. Mavharuvhu egedhi anosanganisira castings, forgings, kana zvinhu zvinogadzirwa newelding, kunyangwe dhizaini yekukanda inotonga.

Chimwe chezvinhu zvinonyanya kudiwa zvemavharuvhu egedhi ndechekuti anogona kuvhurwa zvizere nekuvharika kudiki kana kupesana mumakomba ekuyerera. Kuramba kuyerera kunopiwa nevhavha yegedhi rakazaruka inenge yakafanana neyechikamu chepombi ine saizi yechiteshi. Naizvozvo, mavharuvhu emagedhi achiri kutariswa zvakanyanya kuvharira kana pa/kudzima maapplication. Mune mamwe mazita evharuvhu, mavharuvhu emagedhi anonzi mavharuvhu epasi.

Mavharuvhu egedhi kazhinji haana kukodzera kudzora kuyerera kana kushanda mune chero nzira kunze kwekuzara kuvhurika kana kuvharwa kwakazara. Kushandisa gedhi regedhi rakavhurika zvishoma kuti ritenderere kana kudzora kuyerera kunogona kukuvadza ndiro yevharuvhu kana mhete yechigaro chevharuvhu, nekuti munzvimbo yakavhurika zvishoma inoyerera inokonzera mhirizhonga, nzvimbo dzechigaro chevharuvhu dzinobonderana.

Gedhi vharafu maitiro

Kubva kunze, mavharuvhu mazhinji emagedhi anotaridzika akafanana. Zvisinei, pane zvakawanda zvakasiyana dhizaini mikana. Mavharuvhu mazhinji emagedhi ane muviri nebhoneti, ine chinhu chinovhara chinonzi disc kana gedhi. Chinhu chekuvhara chinobatanidzwa kune dzinde rinopfuura nepakati pebhoneti uye pakupedzisira kune handwheel kana imwe dhiraivha yekushandisa hunde. Kudzvinyirirwa kwakatenderedza tsinde yevharuvhu kunodzorwa nekutakura kuri kumanikidzwa munzvimbo yekurongedza kana mukamuri.

Kufamba kweplate yevharuvhu yegedhi pahunde yevharuvhu kunoratidza kuti dzinde revharuvhu rinokwira here kana kuti masiruu mundiro yevharuvhu panguva yekuvhura. Kuita uku kunotsanangurawo maviri makuru dzinde/madhisiki masitayipi emavharuvhu egedhi: dzinde rinokwira kana risingasimuke dzinde (NRS). Hunde inosimuka ndiyo inonyanya kufarirwa hunde/dhisiki dhizaini mumusika weindasitiri, ukuwo dzinde risingasimuke rakafarirwa kare neindasitiri yemvura nemapombi. Mamwe maapplication engarava achiri kushandisa mavharuvhu emagedhi uye ane nzvimbo diki anoshandisawo maNRS maitiro.

Iyo yakajairika hunde/bhoneti dhizaini pamavharuvhu eindasitiri ndeyekunze shinda uye joko (OS&Y). Iyo OS&Y dhizaini yakanyatso kuenderana nenzvimbo dzinoita ngura nekuti tambo dziri kunze kwenzvimbo yemvura chisimbiso. Iyo yakasiyana kubva kune mamwe magadzirirwo ekuti handwheel yakabatanidzwa kune bushing kumusoro kwejoko, kwete kune stem pachayo, kuitira kuti handwheel irege kusimuka kana valve yakazaruka.

Gedhi valve musika segmentation

Kunyangwe mumakore makumi mashanu apfuura, kona yekurudyi mavharuvhu atora chikamu chikuru mumusika wevharuvhu wegedhi, mamwe maindasitiri achiri kuvimba nawo zvakanyanya, kusanganisira indasitiri yemafuta negasi. Kunyangwe mavharuvhu ebhora afambira mberi mumapaipi egasi chaiwo, mafuta asina kukora kana mapaipi emvura achiri nzvimbo yemavharuvhu egedhi akagarisana.

Panyaya yehukuru hukuru, mavharuvhu emagedhi achiri sarudzo huru yezvikumbiro zvakawanda muindasitiri yekunatsa. Iko kusimba kwekugadzira uye mutengo wakazara wemuridzi (kusanganisira hupfumi hwekugadzirisa) ndiwo mapoinzi anodiwa echinyakare dhizaini.

Panyaya yekushandiswa, maitiro mazhinji ekunatsa anoshandisa tembiricha yakakwira kupfuura tembiricha yakachengeteka yeTeflon, inova ndiyo chigaro chikuru chemavharuvhu ebhora anoyangarara. High performance butterfly valves uye simbi yakavharwa mavharuvhu ebhora ari kutanga kuwedzera kushandiswa mukunatsa zvikumbiro, kunyangwe mutengo wavo wese wevaridzi kazhinji wakakwirira kupfuura iwo wemavharuvhu egedhi.

Indasitiri yemiti yemvura ichiri kutungamirirwa nemavharuvhu egedhi resimbi. Kunyangwe mumashandisirwo akavigwa, akachipa uye anogara kwenguva refu.

Iyo indasitiri yemagetsi inoshandisaalloy gedhi mavharuvhuyezvikumbiro zvinosanganisira kumanikidza kwakanyanya uye tembiricha yakanyanya. Kunyangwe mamwe mavharuvhu matsva eY-mhando yepasi uye simbi akagara bhora mavharuvhu akagadzirirwa kuvharisa sevhisi awanikwa musimba remagetsi, mavharuvhu emagedhi achiri kufarirwa nevagadziri vezvirimwa nevashandisi.
