Yintoni ivelufa yebhola yetrunnion eneMoto?
AIvalve yebhola yetrunnion enemotokuthetha ukuba ibhola linyanzeliswa ngeebheringi kwaye ivunyelwe kuphela ukujikeleza, ubuninzi bomthwalo we-hydraulic buxhaswa yiMithintelo yeNkqubo, okubangelwa ukunyanzeliswa koxinzelelo oluphantsi kwaye akukho ukukhathala kwe-shaft.
Uxinizelelo lombhobho luqhubela isitulo esinyukayo ngokuchasene nebhola emileyo ukuze uxinzelelo lomgca lunyanzelise isitulo esinyukayo singene ebholeni ibangele ukuba ivaleke.I-anchoring yoomatshini yebhola ifunxa ukutyhala ukusuka kuxinzelelo lomgca, ukuthintela ukukhuhlana okugqithisileyo phakathi kwebhola kunye nezihlalo, ngoko ke naxa itorque yokusebenza iphantsi.Oku kunenzuzo ngakumbi xa ivalve yebhola ivuliwe kuba inciphisa ubungakanani be-actuator kwaye yiyo loo nto iindleko zizonke zephakheji yokuvula ivalve.
Izinto ezilungileyo zoyilo lwebhola ye-trunnion yi-torque ephantsi yokusebenza, ukusebenza ngokulula, ukunxiba kwesihlalo esincitshisiweyo (i-Stem / ibhola yodwa ikhusela ukulayishwa kwecala kunye nokunxiba kwezihlalo ezisezantsi eziphucula ukusebenza kunye nobomi benkonzo), ukusebenza kokutywinwa okuphezulu kuxinzelelo oluphezulu kunye noluphantsi (eyahlukileyo indlela yasentwasahlobo kunye noxinzelelo lomgca onyukayo isetyenziswa njengokutywina ngokuchasene nebhola emileyo kuxinzelelo oluphantsi kunye nezicelo zoxinzelelo oluphezulu).
Iimpawu eziphambili ze-NORTECH Ivalve yebhola ye-trunnion eneMoto
1.Ibhlokhi ephindwe kabini kunye ne-Bleed (DBB)
Xa ivalve ivaliwe kwaye i-valve ephakathi ikhutshwe ngevalve yokukhupha, izihlalo eziphezulu kunye nezisezantsi ziya kubhloka ngokuzimeleyo.Omnye umsebenzi wesixhobo sokukhupha kukuba isihlalo sevalve sinokujongwa ukuba kukho ukuvuza ngexesha lovavanyo.
11.Blow-out Isiqu sobungqina
Isiqu samkela ubume bobungqina bokuvuthela. Isiqu senziwe saneenyawo emazantsi aso ukuze ngokumiswa kwesigqubuthelo esingasentla kunye nesikrufu, isikhondo asiyi kuvuthelwa sisiphakathi nokuba kunyuke uxinzelelo olungaqhelekanga. umgodi wevalve.
Isiqu sobungqina bokuvuthuza
2.ITorque yokuSebenza ephantsi
Ivalve yebhola yombhobho wetrunnion ithatha ubume bebhola yetrunnion kunye nesitulo sevalvu edadayo, ukuze kuzuzwe itorque esezantsi phantsi koxinzelelo lokusebenza.Isebenzisa i-PTFE yokuzithambisa kunye nentsimbi etyibilikayo ekunciphiseni i-coefficient ye-friction ukuya kweyona iphantsi ngokubambisana nobunzulu obuphezulu kunye nesiqu esiphezulu sokulunga.
I-3.Isixhobo sokutywinwa ngokuNgxamisekileyo
Iivalvu zebhola ezinobubanzi obungaphezulu okanye obulingana ne-6'(DN150) zonke ziyilwe ngesixhobo sokutofa esitywiniweyo kwisikhondo nakwisihlalo.Xa i-ring yesihlalo okanye i-stem O yeringi yonakele ngenxa yengozi, isitywini esihambelanayo sinokutofwa ngesixhobo sokutofa esitywiniweyo ukunqanda ukuvuza okuphakathi kwiringi yesitulo kunye nesiqu.
13.Isiqu Sokwandiswa
Ngokuphathelele ivalve efakelweyo, isiqu sokwandisa sinokubonelelwa ukuba umsebenzi womhlaba uyafuneka.Isikhondo sokwandiswa senziwe sisikhondo, ivalve yesitofu sealant, kunye nevalve yokukhupha amanzi enokwandiswa ukuya phezulu ukwenzela ukuba kube lula ukusebenza.Abasebenzisi kufuneka babonise iimfuno zokwandiswa kwesikhondo kunye nobude xa befaka iiodolo.Kwivalve yebhola eqhutywa ngombane, i-pneumatic kunye ne-pneumatic - i-hydraulic actuators, ubude besiqu sokwandisa kufuneka busuke kumbindi wombhobho ukuya kwiflange ephezulu.
Isazobe somzobo wesiqu esongezelelweyo
4.UYilo lweSakhiwo soMlilo
Kwimeko yomlilo ngexesha lokusetyenziswa kwevalve, isihlalo sokuhlala, i-stem O ring kunye ne-flange ephakathi ye-O ring eyenziwe nge-PTFE, irabha yezinye izinto ezingezona zentsimbi iya kuchithwa okanye yonakaliswe phantsi kobushushu obuphezulu.Ngaphantsi koxinzelelo lwe-medium, ibhola ivelufa iya kutyhala isigcini sesitulo ngokukhawuleza ukuya ebholeni ukwenza umsesane wokutywina wentsimbi uqhagamshelane nebhola kwaye wenze intsimbi encedisayo kwisakhiwo sokutywina sesinyithi, esinokulawula ngokufanelekileyo ukuvuza kwevalvu.
5.Anti-static Structure
Ivalve yebhola iyilwe kunye ne-anti-static structure kwaye yamkele isixhobo sokukhupha umbane ongatshintshiyo ukuba yenze ngokuthe ngqo ijelo engatshintshiyo phakathi kwebhola kunye nomzimba ngesiqu, ukuze kukhutshwe umbane ongatshintshiyo oveliswe ngenxa yokungqubana ngexesha lokuvulwa nokuvalwa. ibhola kunye nesihlalo kumbhobho, ukunqanda umlilo onokuthi ubangelwe yintlantsi engatshintshiyo kunye nokuqinisekisa ukhuseleko lwenkqubo.
Icala elisezantsi: Emva kokuba uxinzelelo "Pb" ngaphakathi kwe-valve Cavity yanda, amandla afakwe kwi-A3 aphezulu kuno-A4.Njengoko i-A3-A4=B2, umahluko woxinzelelo kwi-B2 uya koyisa amandla entwasahlobo ukwenza isitulo sikhululwe ebholeni kwaye siqonde ukukhululeka koxinzelelo lwevalvu yendawo ukuya kwindawo esezantsi emva koko, isihlalo kunye nebhola ziya kutywinwa kwakhona phantsi kwentshukumo yasentwasahlobo. .
8. Ukutywinwa kabini (ipiston ephindwe kabini)
Ivalve yebhola yombhobho wetrunnion inokuyilwa kunye nesakhiwo sokutywina kabini phambi nasemva kwebhola ukulungiselela iimeko ezithile zenkonzo eyodwa kunye neemfuno zomsebenzisi.Inomphumela wepiston kabini.Phantsi kwemeko eqhelekileyo, ivalve ngokubanzi ithatha ukutywinwa okuphambili.Xa isihlalo esisitywinayo sonakele kwaye sibangela ukuvuza, isihlalo sesibini sinokudlala umsebenzi wokutywina kunye nokwandisa ukuthembeka kokutywina.isihlalo samkela isakhiwo esidityanisiweyo.Itywina eliphambili yintsimbi ukuya kwitywina lesinyithi.Itywina lesibini yirubha ye-fluorine O ring enokuqinisekisa ukuba ivalve yebhola inokufikelela kwinqanaba le-bubble yokutywinwa.Xa umahluko woxinzelelo usezantsi kakhulu, isihlalo sokutywina siyakucinezela ibhola kwintshukumo yasentwasahlobo ukuze kuqatshelwe ukutywinwa kokuqala.Xa umahluko woxinzelelo unyuka, amandla okutywinwa kwesihlalo kunye nomzimba aya kunyuka ngokufanelekileyo ukuze utywine ngokuqinileyo isihlalo kunye nebhola kunye nokuqinisekisa ukusebenza kakuhle kokutywinwa.
Ukutywinwa okuphambili: Phezulu.
Xa umahluko woxinzelelo usezantsi okanye kungekho mahluko woxinzelelo, isitulo esidadayo siya kuhamba nge-axially ecaleni kwevalve phantsi kwentshukumo yasentwasahlobo kwaye sityhalele isitulo ngakwibhola ukugcina ukutywinwa okuqinileyo.Xa isihlalo sevalve singaphezulu kwamandla asetyenziswayo kwindawo A1, A2- A1=B1. Ke ngoko, amandla kwi-B1 aya kutyhala isitulo ukuya ngaseBholeni kwaye aqonde ukutywinwa okuqinileyo kwendawo enyukayo.
9.Isixhobo soNcedo loKhuseleko
Njengoko ivalve yebhola yenzelwe ukutywinwa okuphambili kunye nokutywinwa kwesibini okunempembelelo yepiston ephindwe kabini, kwaye umgodi ophakathi awunakukwazi ukuqonda ukukhululeka koxinzelelo oluzenzekelayo, ivalve yokhuseleko kufuneka ifakwe emzimbeni ukuze kuthintelwe ingozi yomonakalo ongaphaya koxinzelelo. ngaphakathi kwendawo yevalve enokuthi yenzeke ngenxa yokwandiswa kwe-thermal medium.Enye ingongoma ekufuneka iqwalaselwe kukuba i-valve yoncedo yokhuseleko ikhutshelwa ngqo emoyeni.Kwimeko yokukhutshwa ngokuthe ngqo kwi-atmospheric akuvumelekanga, sicebisa ukuba i-valve yebhola enesakhiwo esikhethekileyo sokunciphisa uxinzelelo oluzenzekelayo ngokubhekiselele kumlambo ophezulu kufuneka isetyenziswe.Jonga oku kulandelayo ngeenkcukacha.Nceda uyibonise ngokolandelelwano ukuba awufuni ivelufa yoncedo yokhuseleko okanye ukuba ungathanda ukusebenzisa ivalve yebhola enesakhiwo esikhethekileyo sokunciphisa uxinzelelo oluzenzekelayo ukuya kumsinga ongentla.
10.Ulwakhiwo oluKhethekileyo loNcedo oluSebenzayo lokuNxinzelela kuMsinga oPhezulu
Njengoko ivalve yebhola yenzelwe ukutywinwa okuphambili kunye nokutywinwa kwesibini okunesiphumo sepiston ephindwe kabini, kwaye umgodi ophakathi awunakukwazi ukukhupha uxinzelelo oluzenzekelayo, ivalve yebhola idizayini ekhethekileyo iyacetyiswa ukuba ihlangabezane neemfuno zoxinzelelo oluzenzekelayo kwaye iqinisekise ukuba akukho ngcoliseko. Kwimeko engqongileyo. Kwisakhiwo, umlambo ongentla uthatha ukutywinwa okuphambili kwaye umlambo osezantsi uthatha ukutywinwa kokuqala kunye nesibini Xa ivalve yebhola ivaliwe, uxinzelelo kwi-valve cavity inokuqonda ukukhululeka koxinzelelo oluzenzekelayo kumsinga ongasentla, ukuze ugweme. Xa isitulo sokuqala sonakele kwaye sivuza, isihlalo sesibini sinokudlala umsebenzi wokutywina. Kodwa ingqwalasela eyodwa iya kuhlawulwa kwicala lokuhamba kwevalve yebhola ngexesha lofakelo. izalathiso ezisezantsi zomlambo.Jonga le mizobo ilandelayo yomgaqo wokutywina wevalve enesakhiwo esikhethekileyo
Umzobo womgaqo wevalvu yebhola ephuma phezulu nasezantsi
Umzobo womgaqo wokuthomalalisa uxinzelelo lwevalvu yevalve kumsinga ongasentla kunye nokutywinwa komsinga osezantsi
