Sephahla sa plug ke mofuta oa phetoho e potlakileng ka valve hobane e ka thibela ka botlalo ho kopana le phallo ea phallo ka ho tsamaea lipakeng tsa sebaka se koalang ka ts'ebetso ea ho hlakola le ho bula ka botlalo, e leng se etsang hore hangata e sebelisoe bakeng sa mecha ea litaba e nang le likaroloana tse emisitsoeng. Bonolo ba eona ba ho ikamahanya le li-channel tse ngata ho bolela hore valve e ka fumana litsela tse peli, tse tharo, kapa tse 'nè tse arohaneng. Sena se etsa hore moralo oa liphaephe o be bonolo le ho theola bongata ba li-valve le likhokahano tse hlokahalang bakeng sa lisebelisoa.
Lintlha tse latelang tse 'nè li lokela ho nahanoa ha u kenya valve ea plug e le ho e sireletsa kotsing le ho etsa bonnete ba hore e sebetsa ka hohle kamoo e ka khonang:
1. Etsa bonnete ba hore valve e bulehile. Chesa phala pele. Fetisetsa mocheso o mongata kamoo ho ka khonehang ho tloha phala ho ea ho valve ea mokoko. Qoba ho eketsa nako ea ho futhumatsa ea valve ea plug ka boeona.
2. Ho etsa hore likarolo tsa tšepe tsa liphaephe le likarolo tse sehiloeng li khanye, li hloekise ka gauze kapa brush ea terata. Ha e eletsoa ho apara velvet ea tšepe.
3. Ntlha ea pele, khaola phala ka holimo, li-burrs li lokela ho fokotsoa le ho tlosoa, 'me bophara ba pipe bo lokela ho lekanyetsoa.
4. Hlakola ka hare ho sekoahelo sa weld le bokantle ba phala. Sebaka sa weld se hloka ho koaheloa hantle ka phallo. Ka kopo, ela hloko ha u sebelisa flux.
Mefuta e fapaneng ea moralo oa li-valve tsa plug ea JLPV e tjena:
1. Boholo: 2 "ho ea 14" DN50 ho DN350
2. Khatello: Sehlopha sa 150lb ho isa ho 900lb PN10-PN160
3. Boitsebiso: tšepe ea carbon, tšepe e sa hloekang le lisebelisoa tse ling tse tloaelehileng tsa tšepe.
NACE MR 0175 thepa ea tšepe e khahlanong le sebabole le e khahlanong le kutu.
4. Khokahano e fella: ASME B 16.5 sefahlehong se phahamisitsoeng(RF), sefahleho se bataletseng(FF) le Ring Type Joint (RTJ）
ASME B 16.25 pheletsong e sekalaneng.
5. Litekanyo tsa sefahleho le sefahleho: li lumellana le ASME B 16.10.
6. Mocheso: -29℃ ho ea ho 450℃
Li-valve tsa JLPV li ka ba le li-gear operator, li-pneumatic actuators, li-hydraulic actuators, li-actuator tsa motlakase, li-bypasses, lisebelisoa tsa ho notlela, li-chainwheels, li-stems tse atolositsoeng le tse ling tse ngata ho finyella litlhoko tsa bareki.
