Uhlalutyo lwemigaqo yokusebenza kunye neempawu zesakhiwo sevalve yeglowubhu yeflange yombane
Kwiinkqubo zemibhobho yoshishino, iivalve zeglobhu zombane luhlobo oluqhelekileyo lwevalve, ezisetyenziswa ngokubanzi kwiindawo ezahlukeneyo zoshishino ngenxa yokusebenza kwazo ngokufanelekileyo kunye nesiphumo sokutywinwa esithembekileyo. Ukuze uqonde kakuhle umgaqo wokusebenza kunye neempawu zesakhiwo sale valve, siya kuqhuba uhlalutyo olunzulu.
Okokuqala, makhe siphonononge ubume obusisiseko beevalvu zeglowubhu yeflange yombane. Olu hlobo lwevalvu ikakhulu luqulathe amacandelo afana nomzimba wevalve, isigqubuthelo sevalvu, idiskhi yevalvu, isiqu sevalvu, ikhonkco lokutywina, kunye ne-actuator yombane. Phakathi kwabo, umzimba wevalve yeyona ndawo iphambili yevalve, edla ngokudityaniswa nenkqubo yombhobho ngoqhagamshelo lweflange. Isigqubuthelo sevalve sigquma ngaphezu komzimba wevalve, sibonelela ngokhuseleko lwesiqu sevalve. Idiskhi yevalvu yinxalenye ephambili yokufezekisa ukutywinwa, ebekwe kumgodi ongaphakathi womzimba wevalvu kwaye ifezekisa ukutywinwa ngokunxibelelana ngokusondeleyo nesitulo sevalvu. Isiqu sevalve yinxalenye ebalulekileyo edibanisa i-actuator yombane kunye ne-valve disc. Idlulisela amandla e-actuator kwi-disc ye-valve, ukufezekisa ukuvulwa nokuvalwa kwevalve. Umsesane wokutywina usetyenziselwa ukuphucula ukusebenza kokutywinwa kwevalve kunye nokuthintela ukuvuza okuphakathi. Okokugqibela, ii-actuator zombane zingumthombo wamandla wokusebenza kwevalve, enokuba ziimotor zombane, i-pneumatic okanye i-hydraulic actuators, njl.
Okulandelayo, siya kuhlalutya umgaqo osebenzayo wevalve yeglowubhu yeflange yombane. Xa i-actuator yombane ifumana isignali yokulawula, iya kuqhuba isiqu sevalve ukuba siye phezulu nasezantsi. Njengoko isiqu sevalve sihamba, idiski yevalve nayo iya kunyuka okanye iwe ngokufanelekileyo. Xa i-disc yevalve iphakama kwaye ishiya isihlalo sevalve, ivalve iyavula kwaye i-medium ingadlula; Xa i-disc yevalve ihla kwaye idibana ngokusondeleyo nesihlalo sevalve, ivalve iyavala kwaye ukuhamba kwe-medium kuyanqanyulwa. Kule nkqubo, iringi yokutywina idlala indima ebalulekileyo ekuqinisekiseni ukuba ivalve ayivuzi xa ivaliwe. Ukongezelela, ulawulo oluchanekileyo lokuhamba lunokufezekiswa ngokulungelelanisa ubude be-stroke ye-actuator.
Iimpawu zesakhiwo sevalvu yeglowubhu yeflange yombane zibonakaliswa ikakhulu kule miba ilandelayo:
1. Idityaniswe kakhulu: Amacandelo aphambili e-valve ahlanganiswe kumzimba we-valve, okwenza ukuba isakhiwo se-valve sidibanise kwaye sithathe indawo encinci.
2. Kulula ukusebenza: Iqhutywa yi-actuator yombane, kulula ukuyisebenzisa kwaye inesantya sokuphendula ngokukhawuleza. Abasebenzisi badinga kuphela ukuthumela imiyalelo ngenkqubo yokulawula ukufikelela kulawulo olukude.
3. Ukusebenza kakuhle kokutywinwa: Izinto zokutywina ezikumgangatho ophezulu kunye nezakhiwo zokutywinwa ezicwangcisiweyo zisetyenziselwa ukuqinisekisa ukuba i-valve inokugcina imiphumo emihle yokutywinwa phantsi kweemeko ezahlukeneyo zokusebenza.
4. Ukhuseleko kunye nokuthembeka: I-valve ye-globe ye-flange yombane ineendlela ezininzi zokukhusela, ezifana nokukhuselwa kokugqithiswa, ukukhuselwa kokuvuza, njl., Ukuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo kwezixhobo.
5. Ukusetyenziswa okubanzi: Ngenxa yokusetyenziswa koqhagamshelwano lwe-flange, i-valve inokudibanisa ngokulula kunye nezinye iinqununu ze-pipeline ezixhunyiwe kwi-flange, okwenza ukuba ifaneleke kwiindawo ezahlukeneyo zoshishino.
Isishwankathelo, iivalvu zeglowubhu yeflange yombane zidlala indima ebalulekileyo kwiinkqubo zemibhobho yeshishini ngenxa yomgaqo-nkqubo wazo osebenzayo kunye neempawu ezizodwa zesakhiwo. Ukuqonda umgaqo wayo wokusebenza kunye neempawu zesakhiwo kusinceda ukuba sikhethe ngcono kwaye sisebenzise le valve, ngaloo ndlela siqinisekisa ukhuseleko, ukusebenza kakuhle, kunye nokuthembeka kwemveliso yoshishino.
