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 ye-weld 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.
