Ivalve yeBhola edadayo
Yintoni ivalve yebhola edadayo?
A Ivalve yeBhola edadayousebenzisa ibhola ejikelezayo kunye nesiqu esibonelela ngolawulo lokuvula/ukuvala.
Iivalve yebhola edadayosebenzisa uxinzelelo lomgca wendalo ukucofa kunye nokutywina ibhola kwisitulo esisezantsi.Uxinzelelo lomgca lubonakaliswe kwindawo enkulu - ubuso obuphezulu bebhola, eyona ndawo ilingana nobukhulu bombhobho wangempela.
A ivalve yebhola edadayoyivalve enebhola edadayo (engamiselwanga yitrunnion) ngaphakathi kumzimba wevalve, ikhukuliseka iye kwicala elisezantsi lomlambo kwaye ityhale ngokuqinileyo kwisitulo phantsi koxinzelelo oluphakathi ukuqinisekisa ukuthembeka kokutywinwa.Ivalve yebhola edadayo inesakhiwo esilula, ukusebenza kakuhle kokutywina kodwa izinto zokuhlala ziyafuneka ukuze zimelane nomthwalo wokusebenza ekubeni uxinzelelo lokutywinwa luvalwa ngumsesane wokuhlala.Ngenxa yokungafumaneki kwezixhobo zokuhlala eziphezulu, ivalve yebhola edadayo isetyenziswa ikakhulu kuxinzelelo oluphakathi okanye oluphantsi.
Xa ivalve ibekwe apho ibhore ilungelelaniswe kwicala elinye nombhobho, ikwindawo evulekileyo, kwaye ulwelo lunokudlula ezantsi.I-NORTECHIvalve yebhola edadayo yimveliso entsha eyenziwe yinguqu kwivalve eqhelekileyo kunye nokwamkelwa komgangatho wehlabathi ohlaziyiweyo.
Iimpawu eziphambili ze-NORTECH ivelufa yebhola edadayo?
1. Uyilo lweZitulo eziKhethekileyo
samkela uyilo lwesakhiwo seringi esiguquguqukayo sevalve yebhola edadayo.Xa uxinzelelo oluphakathi luphantsi, indawo yoqhagamshelwano yomsesane wokutywina kunye nebhola incinci.Iya kunciphisa i-friction kunye ne-torque yokusebenza kwaye iqinisekise ukuqina ngexesha elifanayo.Xa uxinzelelo oluphakathi lunyuswa, indawo yoqhagamshelwano yentsimbi yokutywina kunye nebhola iba nkulu kunye ne-elastic deformation ye-ring ye-ring, ngoko ke umsesane wokutywina unokunyamezela i-medium ephezulu. impembelelo ngaphandle kokulimala.

2. Uyilo lweSakhiwo esingangenwa ngumlilo
Kwimeko yomlilo ngexesha lokusetyenziswa kwevalve, iringi yesitulo esenziwe nge-PTFE Okanye ezinye izinto ezingezizo ezentsimbi ziyakubola okanye zonakaliswe phantsi kobushushu obuphezulu kwaye oko kuya kubangela ukuvuza okumandla kolwelo, kuyingozi kakhulu kwinto enokutsha okanye eqhumayo. Umsesane wokutywina ongenamlilo ubekwe phakathi kwebhola kunye nesihlalo ukuze emva kokuba isitulo sevalve sitshisiwe, indawo ephakathi iya kutyhala ibhola ngokukhawuleza ukuya kumjelo osezantsi wokutywina wentsimbi ukwenza intsimbi encedisayo kwisakhiwo sokutywina esinokulawula ngokufanelekileyo ukuvuza kwevalve. Ukongeza, i-gasket ye-flange yokutywina ephakathi, enokuqinisekisa ukutywinwa naphantsi kobushushu obuphezulu .Uyilo lwesakhiwo esingenamlilo sevalve yebhola edadayo ihambelana neemfuno ze-APl607, APl6FA, BS 6755 kunye neminye imigangatho.

3. Ulwakhiwo lwe-Anti-static
Ivalve yebhola iyilwe nge-anti-static structure kunye nesixhobo sokukhupha umbane ongatshintshiyo ukwenza ngqo umjelo ongatshintshiyo phakathi kwebhola kunye nomzimba ngesiqu ukuze kukhutshwe umbane ongatshintshiyo oveliswe ngokukhuhlana kwebhola kunye nesihlalo, ukuphepha umlilo okanye ugqabhuko-dubulo. oko kunokubangelwa kukukhazimla okumileyo kunye nokuqinisekisa ukhuseleko lwenkqubo.

4. Ukutywinwa okuthembekileyo kweSikhondo seValve
Isiqu senziwe ngegxalaba emazantsi alo ukuze singavuthelwa liphakathi naphantsi kwemeko egqithisileyo njengokunyuka koxinzelelo olungaqhelekanga ngaphakathi kumngxunya wevalve, ukusilela kwepleyiti yedlala kunye nokunye Ukongeza, ukunqanda ukuvuza emva ukupakishwa kwesikhondo kutshiswe xa kuthe kwatsha, i-thrust bearing ibekwe kwindawo apho igxalaba lesiqu kunye nokudibana nomzimba ukwenza isitulo sokutywina esibuyela umva.Amandla okutywinwa kwetywina elibuyela umva aya kwanda ngokonyuka koxinzelelo oluphakathi, ukuze kuqinisekiswe ukutywinwa kwesiqu esithembekileyo phantsi koxinzelelo olwahlukeneyo, thintela ukuvuza kunye nokuphepha ukusasazeka kwengozi. Isakhiwo sokutywina sohlobo lwe-V senzelwe isikhondo, uhlobo lwe-V. ukupakisha kunokutshintsha ngokufanelekileyo amandla ocinezelo kunye namandla aphakathi kwegland kumandla okutywinwa kwesiqu.Ngokweemfuno zabasebenzisi, i-disc spring elayishwe ukupakisha indlela yokucofa inokwamkelwa ukwenza ukutywinwa kokupakishwa kwesikhondo kuthembeke ngakumbi.
Isikhondo esibekwe ezantsi asiyi kuphephetheka phantsi koxinzelelo oluphakathi

5. Isitshixo kunye noThintelo lokuSebenzisa kakubi
Ivalve yebhola yemanuwali inokutshixwa ngesitshixo kwindawo evulekileyo epheleleyo okanye evaliweyo.Iqhekeza le-90 ° elivulekileyo nelivaliweyo elinomngxunya wokutshixa lenzelwe ukuphepha i-valve misoperation ebangelwa yi-opreators engagunyaziswanga, kwaye inokuthintela ukuvulwa okanye ukuvalwa kwevalve, okanye ezinye iingozi ezibangelwa kukungcangcazela kwemibhobho okanye izinto ezingalindelekanga.Isebenza kakhulu ngakumbi kwi-oyile enokutsha kunye neqhumayo, imibhobho yekhemikhali kunye neyezonyango okanye iityhubhu yasendle.Inxalenye esentlokweni yesikhondo efakwe ngesiphatho ithatha uyilo olucaba.Apho ivalve ivulwa khona, isiphatho sihambelana nombhobho, kwaye iimpawu zokuvala zevalve ziqinisekisiwe ukuba zichanekile.
