Intsimbi Eyenziwe Ngobushushu Obuphezulu Uxinzelelo Oluphezulu I-Low Torque Trunnion Mounted Ball Valve Ifektri yaseTshayina
Yintoni ivalvu yebhola ye-trunnion yentsimbi eyenziweyo?
A Ivalvu yebhola ye-trunnion yentsimbi eyenziweyokuthetha 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 ze-NORTECH Forged steel trunnion ball valve
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.
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
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.
5. Ulwakhiwo oluchasene nokuqina
Ivalvu yebhola yenzelwe isakhiwo esingashukumiyo kwaye isebenzisa isixhobo sokukhupha umbane ongashukumiyo ukwenza ngokuthe ngqo umjelo ongashukumiyo phakathi kwebhola nomzimba ngesiqu, ukuze ikhuphe umbane ongashukumiyo oveliswa kukungqubana ngexesha lokuvulwa nokuvalwa kwebhola kunye nesihlalo ngepayipi, ukuthintela umlilo wokuqhuma onokuthi ubangelwe yintlantsi engashukumiyo kunye nokuqinisekisa ukhuseleko lwenkqubo.
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.
8. Ukutywina kabini (i-piston kabini)
Ivalvu yebhola yombhobho we-trunnion ingayilwa ngesakhiwo sokutywina kabini ngaphambi nasemva kwebhola kwiimeko ezithile zenkonzo ekhethekileyo kunye neemfuno zomsebenzisi. Inesiphumo sepiston kabini. Kwimeko eqhelekileyo, ivalvu ngokubanzi isebenzisa ukutywina okuphambili. Xa isihlalo esiphambili sitywina sonakele kwaye sibangela ukuvuza, isihlalo sesibini sinokudlala umsebenzi wokutywina kwaye siphucule ukuthembeka kokutywina. Isihlalo sisebenzisa isakhiwo esidibeneyo. Itywina eliphambili litywina lesinyithi ukuya kwisinyithi. Itywina lesibini yiringi yerabha ye-fluorine O enokuqinisekisa ukuba ivalvu yebhola inokufikelela kwinqanaba lokutywina le-bubble. Xa umahluko woxinzelelo uphantsi kakhulu, isihlalo sokutywina siya kucinezela ibhola ngentshukumo yasentwasahlobo ukuze kufezekiswe ukutywina okuphambili. Xa umahluko woxinzelelo uphakama, amandla okutywina esihlalo kunye nomzimba aya kwanda ngokufanelekileyo ukuze kutywinwe isihlalo kunye nebhola ngokuqinileyo kwaye kuqinisekiswe ukusebenza kakuhle kokutywina.
Ukuvalwa okuphambili: Phezulu.
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 sigcine ukutywinwa okuqinileyo. Xa isihlalo sevalvu siphezulu kunamandla asetyenziswa kwindawo A1,A2-A1=B1. Ke ngoko, amandla aku-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.

Umzobo osisiseko wokunciphisa uxinzelelo lwevalvu yebhola ukuya kumjelo ongasentla kunye nokutywinwa komjelo osezantsi
12. Ukumelana nokugqwala kunye nokumelana noxinzelelo lwe-sulfide
Kushiyelwe isibonelelo esithile sokugqwala ubukhulu bodonga lomzimba.
Isiqu sentsimbi yekhabhoni, umngxuma osisigxina, ibhola, isihlalo kunye neringi yesihlalo zifakwa kwi-nickel plating yamakhemikhali ngokwe-ASTM B733 kunye ne-B656. Ukongeza, izixhobo ezahlukeneyo ezichasene nokugqwala ziyafumaneka ukuze abasebenzisi bazikhethe. Ngokweemfuno zabathengi, izixhobo zevalvu zinokukhethwa ngokwe-NACE MR 0175 / ISO 15156 okanye i-NACE MR 0103, kwaye ulawulo oluqinileyo lomgangatho kunye nokuhlolwa komgangatho kufuneka kwenziwe ngexesha lokwenziwa ukuze kuhlangatyezwane ngokupheleleyo neemfuno kwimigangatho kwaye kuhlangatyezwane neemeko zenkonzo kwindawo yesulfurization.
