Umgaqo wokuSebenza kunye noKhetho loKhetho lweSicelo seFlange yokuHlola iValve

Ivalve yokukhangela ibhekisa kwivalve evula ngokuzenzekelayo kwaye ivale idiski yevalve ngokuxhomekeke ekuhambeni kwesixhobo ngokwaso ukuthintela ukubuya ngasemva kwesiphakathi.Ikwabizwa ngokuba yivalve yokutshekisha, ivalve yendlela enye, ivalve ebuyela umva kunye nevalve yoxinzelelo lwangasemva.Ivalve yokukhangela yeyevalve ezenzekelayo.Umsebenzi wayo ophambili kukuthintela umva we-medium, ukujikeleza okujikelezayo kwempompo kunye nokuqhuba i-motor, kunye nokukhutshwa kwe-container medium.

Umgaqo wokusebenza wevalve yokukhangela

1. Ukuze kuthintelwe ukujikeleza okuphakathi, iivalve zokutshekisha ziya kufakwa kwisixhobo, izixhobo kunye nemibhobho;
2. Iivalve zokuhlola zifanelekile ngokubanzi kwimidiya ecocekileyo, kungekhona kwimidiya equkethe amaqhekeza aqinileyo kunye ne-viscosity ephezulu;
3. Ngokubanzi, ivalve yokuphakamisa ethe tye iya kukhethwa kumbhobho othe tye onedayamitha eyi-50mm;
4. Ngokuchanekileyo ngokuphakamisa ivalve yokukhangela inokufakwa kuphela kumbhobho othe tye;
5. Ngombhobho wokungena wempompo, ivalve ephantsi kufuneka ikhethwe.Ngokuqhelekileyo, i-valve ephantsi ifakwe kuphela kumbhobho othe nkqo kwi-inlet yempompo, kwaye i-medium flowing ukusuka ezantsi ukuya phezulu;
6. Uhlobo oluphakamisayo lunomsebenzi ongcono wokutywina kunye nokuxhatshazwa okukhulu kwamanzi kunohlobo lwe-swing.Uhlobo oluthe tye kufuneka lufakwe kumbhobho othe tye kunye nohlobo oluthe nkqo kumbhobho othe nkqo;
7. Indawo yokufakela i-valve yokukhangela i-swing ayikhawulelwanga.Inokufakwa kwiipayipi ezithe tye, ezithe nkqo okanye ezithambekileyo.Ukuba ifakwe kwimibhobho ethe nkqo, isikhokelo sokuhamba okuphakathi kufuneka sibe ukusuka ezantsi ukuya phezulu;
8. Ivalve yokukhangela i-swing akufanele yenziwe ibe yi-valve encinci ye-diameter, kodwa ingenziwa ibe yingcinezelo ephezulu kakhulu yokusebenza.Uxinzelelo oluqhelekileyo lunokufikelela kwi-42MPa, kwaye i-diameter ye-nominal ingaba nkulu kakhulu, enokufikelela ngaphezu kwe-2000mm.Ngokwezinto ezahlukeneyo zegobolondo kunye netywina, inokusebenza kuyo nayiphi na indlela yokusebenza kunye naluphi na ubushushu obusebenzayo.Okuphakathi ngamanzi, umphunga, irhasi, i-oyile, amayeza, njl njl.
9. I-valve yokukhangela i-swing ifanelekile kuxinzelelo oluphantsi kunye nobubanzi obukhulu, kwaye umcimbi wofakelo ulinganiselwe;
10. Isikhundla sofakelo lwevalve yokujonga ibhabhathane ayikhawulelwanga.Inokufakwa kumbhobho othe tye okanye othe nkqo okanye othotyiweyo;

Umgaqo-siseko we-valve yokutshekisha
Xa ivalve yokujonga ujingi ivulwe ngokupheleleyo, uxinzelelo lolwelo luphantse lungathintelwa, ngoko ke ukuhla koxinzelelo ngevalve kuncinci.Isihlalo sevalve yokukhangela i-lift ibekwe kwindawo yokutywina ye-valve yomzimba.Ngaphandle kokuba i-disc yevalve inokunyuka kwaye iwe ngokukhululekileyo, yonke ivalve ifana nevalve yokumisa.Uxinzelelo lwe-fluid luphakamisa i-disc yevalve ukusuka kwindawo yokutywina yesihlalo sevalve, kwaye ukubuya umva okuphakathi kubangela ukuba i-disc yevalve ibuyele kwisitulo sevalve kwaye inqumle ukuhamba.Ngokwemiqathango yenkonzo, i-disc ye-valve ingaba yizo zonke izakhiwo zetsimbi okanye ifakwe nge-rubber pad okanye i-rubber ring kwi-disc ye-valve.Njengevalve yokumisa, ukudlula kolwelo kwivalve yokujonga i-lift nayo imxinwa, ngoko ke ukuhla koxinzelelo ngevalve yokujonga i-lift kukhulu kunaleyo yevalve yokujonga ujingi, kwaye ukuhamba kwevalve yokujonga ujingi kunqabile.

I-1, ivalve yokukhangela i-Swing: i-disc yevalve yokukhangela i-swing ikwimo yediski kwaye ijikeleza i-shaft ejikelezayo yesitulo sesitulo sevalve.Ngenxa yokuba umjelo okwivalve ulungelelaniswa kwaye ukuchasana kokuhamba kuncinci kunoko kwevalve yokukhangela i-lift, ifanelekile kwizihlandlo ezinobubanzi obukhulu kunye nesantya esiphantsi sokuhamba kunye nokutshintsha okungaqhelekanga, kodwa akufanelekanga ukuhamba kwe-pulsating, kwaye umsebenzi wokutywina awulunganga njengalowo wevalve yokukhangela yokuphakamisa.Ivalve yokukhangela i-Swing yahlulwe ngohlobo olulodwa lwediski, uhlobo lwediski ephindwe kabini kunye nohlobo lwesiqingatha esininzi.Ezi fom zintathu ubukhulu becala zahlulwe ngokwedayamitha yevalvu, ukuze kuthintelwe impembelelo yehydraulic ekubeni buthathaka xa isiphakathi siyeka ukuhamba okanye sibuyela umva.

2, Phakamisa ivalve yokukhangela: ivalve yokutshekisha enediskhi yevalve islayidi ecaleni kombindi othe nkqo womzimba wevalvu.Ivalve yokukhangela iphakamisa inokufakwa kuphela kumbhobho othe tye.Kwivalve yokukhangela i-diameter encinci yoxinzelelo oluphezulu, idiski yevalve inokwamkela ibhola.Ubume bomzimba wevalve yokukhangela i-lift iyafana neyevalve yokumisa (enokuthi isetyenziswe kunye nevalve yokumisa), ngoko ke i-coefficient yayo yokumelana nolwelo inkulu.Ukwakhiwa kwayo kufana nevalve yokumisa, kwaye umzimba wevalve kunye nediski ziyafana nevalve yokumisa.Inxalenye ephezulu yediski yevalve kunye nenxalenye esezantsi yesivalo sevalve icutshungulwa ngomkhono wesikhokelo.Umkhono wediskhi yevalve unokunyuka kwaye uwe ngokukhululekileyo kumkhono wesikhokelo sevalve.Xa i-medium ihamba ezantsi, idiskhi yevalve ivula ngokutyhala okuphakathi.Xa i-medium iyeka ukuhamba, i-disc yevalve iwela kwisitulo sevalve ngokuthe nkqo ukuthintela ukujikeleza okuphakathi.Isalathiso sendlela yokungena ephakathi kunye nejelo lokuphuma ngokuthe ngqo ngokuphakamisa ivalve yokukhangela ixhomekeke kwicala lendawo yesitulo sevalve;Isalathiso sendlela yokungena ephakathi kunye nejelo lokuphuma levalve yokuphakamisa ngokuthe nkqo iyafana naleyo yeshaneli yesitulo sevalvu, kwaye ukuchasana nokuhamba kwayo kuncinci kunoko kuthe ngqo kwivalve yokujonga.

3、 Ivalve yokukhangela ibhabhathane: ivalve yokutshekisha enediski yayo ejikeleza iphini lokuhlala kwisitulo sevalve.Ivalve yokujonga iDisc inesakhiwo esilula kwaye inokufakwa kuphela kumbhobho othe tye kunye nokusebenza kakubi kokutywinwa.

4, Ivalve yokukhangela umbhobho: ivalve enediski etyibilikayo kumgca osembindini womzimba wevalvu.Ivalve yokukhangela umbhobho yivalve entsha.Inomthamo omncinci, ubunzima obulula kunye neteknoloji yokucubungula kakuhle.Ngomnye wemigaqo yophuhliso lwevalve yokutshekisha.Nangona kunjalo, i-coefficient yokumelana nolwelo inkulu kancinane kunaleyo yevalve yokujonga ujingi.

5, ivelufa yokujonga ucinezelo: Le valve isetyenziswa njengebhoyila yokutyisa amanzi kunye nevalve yokuvala umphunga.Inomsebenzi obanzi wokuphakamisa i-valve yokukhangela, i-valve yokumisa okanye i-angle valve.

Ukongezelela, kukho ezinye iivalve zokujonga ezingafanelekanga ukufakwa kwempompo yepompo, njenge-valve ephantsi, uhlobo lwentwasahlobo, uhlobo lwe-Y, njl.
