Flanged Gate Control Valve Inoshanda Sei?

Ona Mufananidzo Mukuru
Mavharuvhu eindasitiri anouya mumagadzirirwo akasiyana uye nzira dzekushanda.Mamwe ndeekuzviparadzanisa nevamwe asi mamwe achingoshanda chete pakupuruzira.

Mune pombi system, kune mavharuvhu anoshandiswa kudzora kudzvanywa, kuyerera kwemazinga uye anofarira.Mavharuvhu akadaro anoshandiswa kutarisa uye kudzora kuyerera kwekuchinja kuitira kuti iyo yekupedzisira inonamira padhuze sezvinobvira kune inodiwa yakatarwa.Nekudaro, iyo vharafu yekudzora ndeimwe yeanonyanya kutorwa kune akabvumidzwa mavharuvhu mupombi sezvo iyi vharafu ine zvirevo izvo mamwe mainjiniya anoona zvakanyanya kuomarara.

Kune marudzi akawanda ekudzora mavharuvhu.Imwe yacho ndeye flanged gedhi rekudzora vharafu.Ichi chinyorwa chinokurukura kuti flanged gedhi rekudzora vharafu rinoshanda sei, mashandisiro ayo uye anofarira.

Chii chinonzi Control Valve?

Netsanangudzo, vharuvhu yekudzora ivhavha chero ipi zvayo inogona kudzora kuyerera kwenhau, kumanikidza kwayo kuyerwa maererano nekunze kwekudzora mudziyo.Kazhinji, mavharuvhu ekudzora anosanganiswa nehurongwa hwekuyerera kwenhau asi izvi zvinogona zvakare kushandura mamwe masisitimu akasiyana.

Iyo valve yekudzora inoonekwa seyakanyanya kukosha chikamu chekutonga loop.Shanduko dzinoitwa nevhavhavha yekudzora inobata zvakananga maitiro nevhavha yakadaro yakabatana.

Mavharuvhu akati wandei anoshanda semavharuvhu ekudzora sezvinoonekwa patafura pazasi.Butterfly uye globe mavharuvhu anogona kushandiswa throttling.Nepo mavharuvhu ebhora uye mavharuvhu epuragi ane throttling cacities, aya haawanzokodzera sevhisi yakadai nekuda kwekugadzirwa kwemhando mbiri idzi.Vanowanzo kanganisa friction.

Kudzora mavharuvhu anosanganisira akasiyana akajairwa kupatsanura.Inogona kunge iine mutsetse wekufamba senge wepasirese, pinch uye diaphragm mavharuvhu.Inogona zvakare kuve nekutenderera kwekufamba senge yebhora, shavishavi uye mavharuvhu eplug.

Kune rumwe rutivi, mavharuvhu ekudzivirira ane simba rekudzikisa kumanikidzwa.Zvakare, vharafu yeglobhu, vharafu yebhora, uye vharafu yeplug zvine kugona kushandura mafambiro ekuyerera kwe media.Zvisinei, pane zvisizvo.Iyo chete angle yeglobe mavharuvhu, multiport bhora uye plug mavharuvhu anogona kushandura nzira yenhau.

Control Valve Features

Kudzora mavharuvhu ayo ari emutsara inofamba mhuri anogona throttle madiki ekuyerera.Yakakodzera kune yakanyanya kudzvanywa maapplication, nzira yekuyerera yerudzi urwu rwevharuvhu yakatenderedzwa.Kupa chisimbiso chiri nani, bhoneti yakaparadzana.Zvibatanidza zvinowanzoitwa flanged kana threaded.

Control Valve Features

Mavharuvhu ane zvigaro zvimwechete anoda simba guru kufambisa dzinde asi anopa kuvharika kwakasimba.Kusiyana neizvi, mavharuvhu epasi-anogara maviri anoda simba diki kufambisa dzinde asi haagone kuwana iyo yakasimba yekuvharira kugona kweiyo-inogara globe valve.Uyezve, zvikamu zvaro zvinopera nyore nyore.

Mavharuvhu ediaphragm, kune rumwe rutivi, anoshandisa chigaro chakafanana nechisharo kuvhara vharafu.Rudzi urwu runowanzo kuwanikwa mumapaipi anobata necorrosive media.

Rotatory motion control valve ine yakawedzera kuyerera nzira yekuyerera ichienzaniswa neiyo linear inofamba mhuri.Inogonawo kupora zvakanaka kubva pakudonha kwekumanikidza.Iyo ine yakawanda midhiya inokwana ine kushoma kupfeka kune kurongedza.Butterfly valves inopa kuvharika kwakasimba uye kuderera-kudonha.

Kudzora Valve Kushanda Mechanism

Sezvambotaurwa, mavharuvhu ekudzora anowanzoshandiswa kugadzirisa mafambiro enhau.Chimwe chezvikonzero nei izvi zvichifanira kuitwa pane shanduko mukuremerwa kwekumanikidza.Kazhinji, pane sensor inovhundutsa sisitimu yekuchinja mune inosiyana system.Mushure meizvi, mutongi anotumira chiratidzo kune valve yekudzora, iyo inoshanda semhasuru, nokudaro, inogadzirisa kuyerera sezvinoonekwa mumufananidzo uri pasi apa:

Chii chinonzi Flanges?

Flanges majoini anobatanidza mavharuvhu, pombi uye zvakafanana kune pombi system.Kuisa chisimbiso kunoitwa kuburikidza nemabhoti kana welds ane gasket pakati.Kuvimbika kwemaflange kunoenderana nekubatana-kuita maitiro maererano nemaitiro ekuchinja.

Kunze kwewelding flanges ndiyo inonyanya kubatanidzwa nzira mupombi system.Kubatsira kweflanges ndeyekuti inobvumira kuvhara kwevhavha, kunyange pasina kubvisa zvikamu zvikuru zvevhavha.
Kazhinji, maflange ane zvinhu zvakafanana nemuviri wevhavha kana pombi.Iyo inonyanya kuzivikanwa zvinhu zveflange ndeye forged kabhoni simbi.Zvimwe zvinoshandiswa zvakanyorwa pasi apa"

Chii chinonzi Flanged Gate Control Valve?

A flanged gedhi vharafu imhando yevharuvhu yegedhi ine magumo anopenya.Iyi imhando yevharuvhu ine basa rinopfuura rimwechete.Izvi zvinogona kuita sevhavha yekuzviparadzanisa nevamwe pamwe nevhavha inorovera.

Kuve vharafu yegedhi, ine mari nekuda kwekugadzirwa kwayo.Uyezve, iyo flanged gedhi rekudzora vharafu rinogona kuvhura kana kuvhara zvakasimba uye haringarasikirwe nemhepo inodonha madonhwe kuitira kuti kuyerera kungoita shanduko shoma.
Kubatanidza actuator uye kure kure pressure drop detector, vharafu yegedhi inova vharuvhu yekudzora.Ne disc yayo, inogona kudonha kune imwe nhanho.

Kuti vharafu ribatanidzwe papombi, maflanges anoda kusungwa uye kusungirirwa kuti achengetedze.Iyo flanged gedhi valve inotevera ASME B16.5 zviyero.Kazhinji, dhizaini iyi inoshandisa wedge type disc sechinhu chekuvhara.
Iri rudzi rwevharuvhu rinoshandiswa mukudzika kwakadzika uye tembiricha yekushandisa.Kuve neunhu hwegedhi revharuvhu, zvakanakira yevhavha yegedhi ine flanged ndeyekuti haina madonhwe ekudzvinyirira.
