The Ductile Iron Soft Seal Seal Valve VS. Valve ea Heke ea tšepe e thata ea Ductile
Li-valve tsa liheke tse bonolo le li-valve tsa heke tse tiileng ke lisebelisoa tse sebelisoang hangata bakeng sa ho laola le ho thibela phallo, ka bobeli li na le ts'ebetso e ntle ea ho tiisa, mefuta e mengata ea ts'ebeliso, 'me ke e' ngoe ea lihlahisoa tseo bareki ba li rekang ho feta. Li-novices tse ling tsa ho reka li ka 'na tsa labalabela ho tseba, tse tšoanang le valve ea heke, phapang e khethehileng pakeng tsa bona ke efe?
Tiiso e bonolo ke tiiso pakeng tsa tšepe le e seng tšepe, ha tiiso e thata e le tiiso pakeng tsa tšepe le tšepe. Li-valve tse bonolo tsa heke le li-valve tsa heke tse tiileng ke lisebelisoa tsa ho tiisa, tiiso e thata e entsoe ka nepo ka thepa ea setulo ho netefatsa ho nepahala ha ho lekana le spool (bolo), hangata tšepe e sa hloekang le koporo. Setiiso se bonolo se kentsoe ka har'a thepa ea ho tiisa setulo sa li-valve ke thepa e seng ea tšepe, ka lebaka la thepa ea tiiso e bonolo e na le tekanyo e itseng ea elasticity, ka hona litlhoko tse nepahetseng tsa ho sebetsa li batla li le tlase ho feta tiiso e thata. Ka tlase ho u isa ho utloisisa phapang lipakeng tsa valve e bonolo ea heke le valve ea heke e thata.
Lisebelisoa tsa ho tiisa pele
1. Lisebelisoa tse peli tsa ho tiisa li fapane. Soft seal heke valve hangata ke rabara kapa PTFE le lisebelisoa tse ling. Belofo e tiileng ea ho tiisa heke e sebelisang tšepe e sa hloekang le litšepe tse ling.
2. Letlapa le bonolo: ho tiisa lehlakore la motlatsi oa mahlakoreng a mabeli a thepa ea tšepe, lehlakoreng le leng la lisebelisoa tse se nang tšepe, tse tsejoang e le "soft seal". Phello ea tiiso ea li-valve tse joalo tsa heke, empa e se mocheso o phahameng, ho bonolo ho apara le ho taboha, le thepa e mpe ea mechine. Tse kang tšepe + rabara; tšepe + PTFE joalo-joalo.
3. Tiiso e thata: ho tiisa ka thata le ho tiisa mahlakoreng ka bobeli ke tšepe kapa lisebelisoa tse ling tse thata. Ho tiisa li-valve tse joalo tsa heke ho fokola, empa ho hanyetsa mocheso o phahameng, ho hanyetsa ho roala, le thepa e ntle ea mochine. Tse kang tšepe + tšepe; tšepe + koporo; tšepe + graphite; tšepe + tšepe ea motsoako; (e ka boela ea sebelisa tšepe e entsoeng ka tšepe, tšepe ea motsoako, motsoako oa pente ea spray, joalo-joalo).
Ea bobeli, mokhoa oa kaho
Indasteri ea mechini e na le tikoloho e rarahaneng ea mosebetsi, eo bongata ba eona e leng mocheso o tlase haholo le khatello e tlase, khanyetso e phahameng ea mecha ea litaba le ho senya. Hona joale, tsoelo-pele ea theknoloji e lebisitse ho phatlalatsoeng ha li-valve tsa heke tse thata.
Ho nahana ka kamano pakeng tsa ho thatafala ha tšepe, valve ea heke e tiileng, le tiiso e bonolo, 'mele oa valve o hloka ho thatafatsoa, le setulo sa valve le setulo sa valve ho lula se sila ho fihlela tiiso. Potoloho ea tlhahiso ea li-valve tsa heke e thata e telele haholo.
Ea boraro, tšebeliso ea maemo
1, tiiso e bonolo e ka lemoha ho lutla ha zero, tiiso e thata e ka fetoloa ho latela litlhoko tsa holimo le tlase;
2, Litiiso tse bonolo li ka 'na tsa lutla tlas'a mocheso o phahameng, li hloka ho ela hloko thibelo ea mollo,' me litiiso tse thata li ke ke tsa lutla tlas'a mocheso o phahameng. Setiiso se thata sa valve se koala se ka sebelisoa khatellong e phahameng, tiiso e bonolo e ke ke ea sebelisoa.
3, bakeng sa mecha ea litaba e senyang, tiiso e bonolo e ke ke ea sebelisoa, u ka sebelisa tiiso e thata;
4, mochesong o tlase haholo, thepa ea tiiso e bonolo e tla lutla, tiiso e thata ha se bothata bo joalo;
Ea bone, khetho ea lisebelisoa ka
Maemo a mabeli a ho tiisa a ka fihla ho tse tšeletseng, hangata a ipapisitse le mokhoa oa tšebetso, mocheso le khatello ea ho khetha valve e nepahetseng ea heke. Bakeng sa mecha ea litaba e akaretsang e nang le likaroloana tse tiileng kapa tse senyang, kapa ha mocheso o feta likhato tse 200, ho molemo ho khetha tiiso e thata. Haeba torque ea valve ea ho koala e le khōlō, u lokela ho khetha ho sebelisa valve e tsitsitseng e tiileng ea heke.
Bohlano, phapang bophelong ba tšebeletso
Molemo oa tiiso e bonolo ke ho tiisa hantle, ho senyeha ke hore ho bonolo ho tsofala, ho senya le ho senya, bophelo bo khutšoanyane. Bophelo ba tšebeletso ea ho tiisa ka thata bo bolelele, 'me ts'ebetso ea ho tiisa e mpe ho feta ho tiisa ha bonolo, tse peli li ka tlatsana.
Lintlha tse ka holimo ke phapang pakeng tsa valve e bonolo ea heke le ho arolelana tsebo ea li-valve tsa heke e thata, ke tšepa hore ke tla khona ho u thusa mosebetsing oa ho reka.
