I-valve yepulaki iwuhlobo lokushintshwa okusheshayo nge-valve ngoba ingase ivimbele ngokuphelele ukuthintana nendawo egeleza ngokunyakaza phakathi kwendawo yokuvala enesenzo sokusula futhi ivuleke ngokugcwele, iyenze ijwayele ukusetshenziselwa imidiya enezinhlayiya ezimisiwe.Ubulula bayo bokujwayela ukwakhiwa kwamashaneli amaningi kusho ukuthi i-valve ingathola kalula amashaneli okugeleza amabili, amathathu, noma amane ahlukene.Lokhu kwenza ukuklama kwamapayipi kube lula futhi kwehlisa nenani lama-valve nokuxhumana okudingekayo kumishini.
Lokhu okulandelayo okucatshangelwayo kufanele kucatshangelwe lapho kufakwa i-valve yepulaki ukuze kuvikelwe ekulimaleni futhi kuqinisekiswe ukuthi isebenza ngokusemandleni ayo aphezulu:
1. Qinisekisa ukuthi i-valve ivuliwe.Shisisa ipayipi kuqala.Dlulisa ukushisa okuningi ngangokunokwenzeka kusuka epayipini kuya kuvalvu yeqhude.Gwema ukwelula isikhathi sokushisa se-valve yepulaki ngokwayo.
2. Ukwenza izindawo zensimbi zamapayipi kanye nezigaba ezisikiwe zikhanye, zihlanze nge-gauze noma ibhulashi locingo.Akukhuthazwa ukugqoka i-velvet yensimbi.
3. Okokuqala, usike ipayipi ngokuqondile, ama-burrs kufanele anqunywe futhi asuswe, futhi ububanzi bepayipi kufanele bulinganiswe.
4. Gubha ingaphakathi lekhava yokushisela kanye nengaphandle lepayipi.I-weld surface idinga ukumbozwa kahle ngokuguquguquka.Sicela uqaphele lapho usebenzisa i-flux.
Ibanga le-JLPV plug valve design limi kanje:
1. Usayizi: 2” kuya ku-14” DN50 kuya ku-DN350
2. Ingcindezi: Ikilasi 150lb ukuya ku-900lb PN10-PN160
3. Material: carbon steel, insimbi engagqwali nezinye izinto ezivamile metal.
I-NACE MR 0175 anti-sulphur kanye nezinto zensimbi ezilwa nokugqwala.
4. Ukuxhumana kuyaphela: ASME B 16.5 ebusweni obuphakanyisiwe(RF), Ubuso obuyisicaba(FF) kanye Nokuhlanganiswa Kohlobo Lwendandatho (RTJ）
I-ASME B 16.25 esiphethweni esiyisikulufu.
5. Ubukhulu bobuso nobuso: buvumelana ne-ASME B 16.10.
6. Izinga lokushisa: -29℃ ukuya ku-450℃
Ama-valve e-JLPV angafakwa ama-gear operator, ama-actuator womoya, ama-hydraulic actuators, ama-actuator kagesi, ama-bypasses, izinto zokukhiya, ama-chainwheel, iziqu ezinwetshiwe nokunye okuningi kuyatholakala ukuze kuhlangatshezwane nezidingo zamakhasimende.
