Zithini iivalvu zebhola ezifakwe kwi-ATEX Trunnion?
I-ATEX ivalvu yebhola efakwe kwi-trunnionkuthetha ukuba ibhola ithintelwe ziibheringi kwaye ivunyelwe ukujikeleza kuphela, uninzi lomthwalo we-hydraulic luxhaswa ziingxaki zeNkqubo, nto leyo ebangela uxinzelelo oluphantsi lweebheringi kwaye kungabikho kudinwa kwe-shaft.
Uxinzelelo lombhobho luqhuba isihlalo esingaphezulu komsinga nxamnye nebhola engashukumiyo ukuze uxinzelelo lomgca lunyanzele isihlalo esingaphezulu komsinga ukuba siye ebholeni nto leyo ebangela ukuba sivale. Ukubambelela kwebhola ngoomatshini kutsala ukutyhalwa koxinzelelo lomgca, kuthintela ukungqubana okugqithisileyo phakathi kwebhola nezihlalo, ngoko ke nokuba kuxinzelelo olupheleleyo lokusebenza olunexabiso eliphantsi, i-torque yokusebenza ihlala iphantsi. Oku kuluncedo ngakumbi xa ivalvu yebhola iqhutywa kuba inciphisa ubungakanani be-actuator kwaye ke ngoko iindleko zizonke zephakheji ye-valve actuation. I-trunnion ifumaneka kuzo zonke iisayizi kunye nazo zonke iindidi zoxinzelelo kodwa ikakhulu zezobukhulu obukhulu kunye neemeko zoxinzelelo oluphezulu.
Iimpawu eziphambili zeevalvu zebhola ezifakwe kwi-NORTECH ATEX Trunnion
1. Ukuvimba kabini kunye nokopha (DBB)
Xa ivalvu ivaliwe kwaye umngxuma ophakathi ukhutshiwe ngevalvu yokukhupha amanzi, izihlalo eziphezulu nezisezantsi ziya kuvala ngokuzimeleyo. Omnye umsebenzi wesixhobo sokukhupha amanzi kukuba isihlalo sevalvu sinokujongwa ukuba kukho ukuvuza ngexesha lovavanyo. Ukongeza, iidipozithi ngaphakathi emzimbeni zinokuhlanjwa ngesixhobo sokukhupha amanzi. Isixhobo sokukhupha amanzi senzelwe ukunciphisa umonakalo kwisihlalo ngenxa yokungcola okukwindawo yokusebenzela.
2. I-Torque eSebenzayo ephantsi
Ivalvu yebhola yombhobho we-trunnion isebenzisa isakhiwo sebhola ye-trunnion kunye nesihlalo sevalvu esintantayo, ukuze ifikelele kwi-torque ephantsi phantsi koxinzelelo olusebenzayo. Isebenzisa i-PTFE ezithambisayo kunye ne-bearing yesinyithi etyibilikayo ukunciphisa i-friction coefficient iye kweyona iphantsi kunye nobunzulu obuphezulu kunye nesiqu esinobunono obuphezulu.
3. Isixhobo sokutywina esingxamisekileyo
Iivalvu zebhola ezinobubanzi obungaphezulu okanye obulingana ne-6' (DN150) zonke zenziwe ngesixhobo sokujova i-sealant kwisiqu nakwisihlalo. Xa iringi yesihlalo okanye iringi yesiqu O yonakele ngenxa yengozi, isitywini esifanelekileyo sinokufakwa kwisixhobo sokujova i-sealant ukuze kuthintelwe ukuvuza okuphakathi kwiringi yesihlalo nakwisiqu. Ukuba kuyimfuneko, inkqubo yokutywina encedisayo ingasetyenziselwa ukuhlamba nokuthambisa isihlalo ukuze kugcinwe ucoceko lwaso.

4. Uyilo lweSakhiwo esingatshiyo
Xa kutsha ngexesha lokusetyenziswa kwevalvu, iringi yesihlalo, iringi yesiqu se-O kunye neringi ye-O ephakathi eyenziwe nge-PTFE, irabha yezinye izinto ezingezizo ezesinyithi iya kubola okanye yonakale phantsi kobushushu obuphezulu. Phantsi koxinzelelo lwe-medium, ivalvu yebhola iya kutyhala i-seat retainer ngokukhawuleza iye ebholeni ukuze yenze iringi yentsimbi iqhagamshelane nebhola kwaye yenze isakhiwo sokuncedisa isinyithi ukuya kwisinyithi, esinokulawula ngokufanelekileyo ukuvuza kwevalvu. Uyilo lwesakhiwo esingatshiyo sevalvu yepipeline ye-trunnion luhambelana neemfuno ezikwi-API 607, API 6FA, BS 6755 kunye neminye imigangatho.
6.Isakhiwo sokutywina isihlalo esithembekileyo
Ukutywinwa kwesihlalo kwenziwa ngokusebenzisa izigcini zesihlalo ezimbini ezidadayo, Zinokudada nge-axial ukuvimba ulwelo, kubandakanya ukutywinwa kwebhola kunye nokutywinwa komzimba. Ukutywinwa kwesihlalo sevalvu ngoxinzelelo oluphantsi kwenziwa ngokuqiniswa kwentwasahlobo. Ukongeza, isiphumo sepiston sesihlalo sevalvu senziwe ngokufanelekileyo, nto leyo eqinisekisa ukutywinwa koxinzelelo oluphezulu ngoxinzelelo lwendlela ngokwayo. Ezi ntlobo zimbini zilandelayo zokutywinwa kwebhola zinokufezekiswa.
7. Ukutywina okukodwa
(Ukuncitshiswa Koxinzelelo Oluzenzekelayo Kwindawo Ephakathi Yevalvu) Ngokubanzi, kusetyenziswa isakhiwo esinye sokutywina. Oko kukuthi, kukho ukutywinwa okuphezulu kuphela. Njengoko kusetyenziswa izitulo zokutywina ezizimeleyo ezithwele intwasahlobo ephezulu kunye nesezantsi, umgodi wevalvu oxinezelekileyo ngaphakathi unokoyisa isiphumo sokuqinisa kwangaphambili sentwasahlobo, ukuze isihlalo sikhululwe ebholeni kwaye sifumane ukukhululeka koxinzelelo oluzenzekelayo ukuya kwindawo esezantsi. Icala elingaphezulu: Xa isihlalo sihamba nge-axial ecaleni kwevalvu, uxinzelelo "P" olusebenza kwinxalenye ephezulu (i-inlet) luvelisa amandla angasemva kwi-A1, Njengoko i-A2 iphezulu kune-A1, i-A2-A1=B1, amandla kwi-B1 aya kutyhala isihlalo siye ebholeni kwaye aqinisekise ukuvalwa okuqinileyo kwenxalenye ephezulu.
Icala elisezantsi: Nje ukuba uxinzelelo "Pb" ngaphakathi kwevalvu Cavity lunyuke, amandla asetyenziswa kwi-A3 aphezulu kunalawo akwi-A4. Njengoko i-A3-A4=B2, umahluko woxinzelelo kwi-B2 uya koyisa amandla entwasahlobo ukuze isihlalo sikhululwe ebholeni kwaye siphumeze uxinzelelo lwe-valve cavity ukuya kwindawo esezantsi emva koko, isihlalo kunye nebhola ziya kuvalwa kwakhona phantsi kwentshukumo yentwasahlobo.
Ukutywinwa kwesibini: Phantsi komsinga.
Xa umahluko woxinzelelo uphantsi okanye kungekho umahluko woxinzelelo, isihlalo esidadayo siya kuhamba nge-axial ecaleni kwevalvu phantsi kwentshukumo yentwasahlobo size sityhale isihlalo siye ebholeni ukuze sihlale sitywinwe kakuhle. Xa uxinzelelo lwe-valve cavity P lusanda, amandla asetyenziswa kwindawo A4 yesihlalo sevalvu ephezulu kunamandla asetyenziswa kwindawo A3, A4- A3=B1. Ke ngoko, amandla akwi-B1 aya kutyhala isihlalo siye ebholeni aze enze ukutywinwa okuqinileyo kwenxalenye ephezulu.
9. Isixhobo soKhuseleko
Njengoko ivalvu yebhola yenzelwe ukutywinwa okuphambili kunye nokwesibini okunesiphumo sepiston ephindwe kabini, kwaye umngxuma ophakathi awukwazi ukwenza ukukhululeka koxinzelelo oluzenzekelayo, ivalvu yokunceda ukhuseleko kufuneka ifakwe emzimbeni ukuze kuthintelwe ingozi yomonakalo ongaphezulu koxinzelelo ngaphakathi komngxuma wevalvu onokwenzeka ngenxa yokwanda kobushushu be-medium. Uqhagamshelo lwevalvu yokunceda ukhuseleko ngokubanzi yi-NPT 1/2. Enye ingongoma ekufuneka iqatshelwe kukuba umngxuma wevalvu yokunceda ukhuseleko ukhutshelwa ngqo emoyeni. Kwimeko apho ukukhupha ngqo emoyeni akuvumelekanga, sicebisa ukuba ivalvu yebhola enesakhiwo esikhethekileyo sokukhulula uxinzelelo oluzenzekelayo ukuya kumsinga ophezulu kufuneka isetyenziswe. Jonga oku kulandelayo ukuze ufumane iinkcukacha. Nceda uyibonise ngokulandelelana ukuba awuyidingi ivalvu yokunceda ukhuseleko okanye ukuba ungathanda ukusebenzisa ivalvu yebhola enesakhiwo esikhethekileyo sokukhulula uxinzelelo oluzenzekelayo ukuya kumsinga ophezulu.
10. Ulwakhiwo oluKhethekileyo loNcedo oluZenzekelayo lokuNciphisa uxinzelelo oluya kuMsinga oPhezulu
Njengoko ivalvu yebhola yenzelwe ukutywinwa okuphambili kunye nokwesibini okuphambili okunesiphumo sepiston ephindwe kabini, kwaye umngxuma ophakathi awukwazi ukukhulula uxinzelelo oluzenzekelayo, ivalvu yebhola kunye nesakhiwo esikhethekileyo iyacetyiswa ukuhlangabezana neemfuno zokunciphisa uxinzelelo oluzenzekelayo kwaye kuqinisekiswe ukuba akukho ngcoliseko kwindalo esingqongileyo. Kwisakhiwo, umjelo ophezulu usebenzisa ukutywinwa okuphambili kwaye umjelo osezantsi usebenzisa ukutywinwa okuphambili nokwesibini. Xa ivalvu yebhola ivaliwe, uxinzelelo kumngxuma wevalvu lunokwenza ukuncitshiswa koxinzelelo oluzenzekelayo kumjelo ongaphezulu, ukuze kuthintelwe ingozi ebangelwa luxinzelelo lomngxuma. Xa isihlalo esiphambili sonakele kwaye sivuza, isihlalo sesibini sinokudlala umsebenzi wokutywinwa. Kodwa ingqalelo ekhethekileyo kufuneka inikwe kwicala lokuhamba kwevalvu yebhola. Ngexesha lokufakelwa. Qaphela imiyalelo ephezulu nesezantsi. Jonga le mizobo ilandelayo yomgaqo wokutywinwa kwevalvu enesakhiwo esikhethekileyo.

11. Isiqu soBungqina bokuqhushumba
Isiqu samkela isakhiwo esingavumeli ukutsha. Isiqu senziwe ngonyawo olusezantsi ukuze xa sibekwe isiciko sangaphezulu kunye nesikrufu, isiqu singavuthelwa yi-medium nokuba kukho ukunyuka okungaqhelekanga koxinzelelo kwivalvu.
Isiqu Esingqina Ukuqhushumba
13. Isiqu solwandiso
Ngokuphathelele ivalvu efakwe ngaphakathi, isiqu solwandiso sinokubonelelwa ukuba kufuneka kusetyenziswe umhlaba. Isiqu solwandiso senziwe ngesiqu, ivalvu yokutshiza i-sealant, kunye nevalvu yokukhupha amanzi enokwandiswa iye phezulu ukuze kube lula ukuyisebenzisa. Abasebenzisi kufuneka babonise iimfuno kunye nobude besiqu solwandiso xa bebeka ii-odolo. Kwivalvu yebhola eqhutywa nge-electric, pneumatic kunye ne-pneumatic - hydraulic actuators, ubude besiqu solwandiso kufuneka bube ukusuka embindini wepayipi ukuya kwi-flange ephezulu.
