Imibuzo neempendulo eziqhelekileyo malunga neValve yokuKhupha iOyile yeZixhobo zokuzalisa iOyile yeMV kunye neHV Transformer

​

Umbuzo 1: Zeziphi iindlela zokuthintela ukusetyenziswa nokugcinwa kweivalvu?
A1: Amanyathelo okhuseleko xa usebenza:
1. Ukuhlolwa ngaphambi koqhagamshelo: Ngaphambi kokusebenza, jonga ukuba izigqubuthelo zokukhusela kwiindawo zokunxibelelanisa iivalvu azikho na, kwaye uqinisekise ukuba iindawo zokunxibelelanisa kunye neendawo zokutywina azonakalanga kwaye azinazo izinto zangaphandle.
2. Uqhagamshelo oluchanekileyo: Sebenzisa izixhobo ezifanelekileyo (ezifana nesikrufu se-torque) ukuqinisa uqhagamshelo nesihlalo se-transformer valve kunye nemibhobho yezixhobo zangaphandle ngokwe-torque ecetyiswayo, ukuqinisekisa ukutywinwa okuthembekileyo kobuso bokuphela kunye nokuphepha ukuqinisa kakhulu okanye ukuqinisa kancinci.
3. Ukuvula nokuvala kakuhle: Xa uvula okanye uvala ivalvu, jika ivili lesandla kakuhle. Musa ukusebenzisa izixhobo ezifana neebha zokwandisa ukuze usebenze ngamandla ukuthintela umonakalo kwisiqu sevalvu okanye kumphezulu wokuvala. Emva kokuvula ngokupheleleyo, kucetyiswa ukuba ujike ivili lesandla kancinci ukuze ukhusele imisonto.
4. Ukuqinisekiswa kwesimo: Emva kokusebenza, qinisekisa ngokucacileyo imeko yevalvu njenge "ivuliwe ngokupheleleyo" okanye "ivaliwe ngokupheleleyo" ngendawo yevili lesandla okanye iimpawu zesalathisi. Ezinye iimodeli zixhotyiswe ngezixhobo zokutshixa, ekufuneka zitshixwe kwiindawo ezibalulekileyo.
Amanyathelo okhuseleko xa kulungiselelwa:
Ukuhlolwa rhoqo: Ngaphambi kokulungiswa kwe-transformer nganye okanye unyango lweoyile, jonga ngamehlo umphandle wevalvu ukuze ubone ukuba akukho zimpawu zokuvuza, umonakalo, okanye umhlwa.
Uvavanyo lomsebenzi: Xa iimeko zivuma, uvavanyo olulula lokutywina lunokwenziwa kunye noqhagamshelo lwezixhobo (njengokujonga uzinzo lwe-vacuum emva koqhagamshelo kunye nokucoca nge-vacuum).
Ukutshintshwa kweSeal: Ukuba ukusebenza kweSeal kuyawohloka emva kokusetyenziswa ixesha elide (njengokuvuza kancinci kweoyile kwisiqu sevalvu), abasebenzi abaziingcali kufuneka batshintshe ipakethe yeSeal okanye ii-O-rings besebenzisa iphakheji yeendawo zokuqala. Abantu abangengabo iingcali akufuneki bahlukanise iindawo eziphambili zevalvu ngokwabo.
Umbuzo 2: Indlela yokukhetha efanelekileyoivalvu yokukhupha ioyilekwi-transformers kunye nezixhobo zokuzalisa ioyile zeenkcukacha ezahlukeneyo?
A2: Ukhetho kufuneka luqwalasele ezi parameter zilandelayo zokufanisa:
1. Ububanzi kunye nendlela yoqhagamshelo: Misela ubungakanani bezibuko zevalvu ngokusekelwe kubungakanani bomphezulu wesihlalo sevalvu esigciniweyo setanki yeoyile yetransformer (njenge-DN25, DN40, DN50, njl.njl.) kunye nefom yoqhagamshelo (njenge-flange standard PN16/DN40, iBritish NPT thread, njl.njl.) ukuqinisekisa uqhagamshelo olubonakalayo.
2. Uxinzelelo kunye nenqanaba le-vacuum: Qinisekisa ukuba uxinzelelo loyilo kunye nenqanaba le-vacuum yevalvu ihlangabezana okanye idlula uxinzelelo oluphezulu olusebenzayo kunye nenqanaba eliphezulu le-vacuum yokusebenza elifunekayo kwizixhobo zokuzalisa ioyile (ezifana nepompo ye-vacuum, ipompo yeoyile) kunye netekhnoloji yokucubungula i-transformer.
3. Ukuhambelana kweoyile yokukhusela: Qinisekisa ukuba zonke izinto zokuvala kunye nezinto ezidibana neoyile yevalvu ziyahambelana ngokupheleleyo nohlobo lweoyile yokukhusela oyisebenzisayo (njengeoyile yeminerali, ioyile yesilicone, i-ester yokwenziwa).
Indawo yokusebenza: Cinga ukuba yindawo eqhelekileyo yangaphakathi/yangaphandle okanye ineemfuno ezikhethekileyo (ezifana nokubanda okuphezulu, ubushushu obuphezulu, ityuwa etshisiweyo, njl.njl.) ukuze kuqinisekiswe ukuba ngaba kufuneka izinto ezikhethekileyo zeqokobhe okanye unyango lomphezulu.
Q3: Ungaqinisekisa njani umgangatho kunye nokuthembeka kweevalvu?
A3: Siqinisekisa umgangatho wevalvu nganye ngeenkqubo ezingqongqo zokuvelisa nokuvavanya:
Uvavanyo lokuqina komoya: Xa ivalvu ivaliwe, igesi eyomileyo necocekileyo (njengomoya okanye initrogen) izaliswa kwi-valve cavity ngoxinzelelo oluthile. Uxinzelelo luyagcinwa ukujonga nakuphi na ukuvuza, kuqinisekiswa ukusebenza kwayo kokuvala phantsi koxinzelelo oluhle.
Uvavanyo lokutywina nge-vacuum: Elinye icala levalvu livaliwe, kwaye elinye icala liqhagamshelwe kwipompo ye-vacuum. Likhutshwa liye kwinqanaba elithile le-vacuum eliphezulu (elifana ne-10 Pa), kwaye izinga lokuhla kwenqanaba le-vacuum lijongwa ngaphakathi kwexesha elithile ukuqinisekisa ukusebenza kwalo kwe-vacuum phantsi kwe-vacuum ephezulu.
Uvavanyo lohlobo: Kuqhutywa iisampulu rhoqo ukuze kuhlolwe ubomi obupheleleyo (ezifana novavanyo lomjikelo wokuvula nokuvala), uvavanyo lomjikelo wobushushu obuphezulu nobuphantsi, kunye novavanyo lokuhambelana neoyile yokukhusela, njl.njl., ukuqinisekisa ukuthembeka kwexesha elide koyilo.
