Iivalvu zokuplaga ezine-cone-shaped plunger zibizwa ngokuba ziivalve zeplagi.Ngokuzijikeleza i-90 degrees, i-port ye-passage kwiplagi inokuvulwa okanye ivalwe, ihlukanise ukusuka kwi-port ye-passage kumzimba we-valve.Iivalve zeplagi kukuvula ngokukhawuleza kunye nokuvala ngokukhawuleza ngeevalvu eziqhele ukusetyenziswa kwimibhobho ephakathi yobushushu obuphantsi efuna ukuvulwa nokuvalwa ngokupheleleyo ngexesha elifutshane.Ukombiwa kweendawo zeoli, ukuveliswa kwezixhobo zothutho nokusulungekiswa, ushishino lwemichiza nepetrochemical, ukuveliswa kwerhasi kunye nerhasi yepetroleum engamanzi, icandelo leHVAC, kunye noshishino ngokubanzi zonke zizisebenzisa kakhulu.Okwesibini, iivalvu zeplagi zingasetyenziselwa ukuthutha ulwelo oluqulethe izinto eziqinileyo kunye namasuntswana amisiweyo.Izinto eziqulethe i-Crystal zinokuthuthwa kusetyenziswa i-valve yeplagi echanekileyo kunye nesakhiwo sejacket ye-insulating.
Oku kulandelayo zizinto eziphambili zoyilo lwevalve yeplagi yeJLPV:
1. Uyilo oluchanekileyo luvumela ukutshintsha ngokukhawuleza, ukuxhathisa ulwelo oluphantsi, kunye nokusebenza ngokukhawuleza kwe-angle stroke.
2. Kukho iindidi ezimbini zezitywina: izitywina ezithambileyo kunye neoli yeoli.
3. Kukho iintlobo ezintathu zesakhiwo: ukuphakamisa, i-ferrule, kunye ne-inverted.
4. Uyilo olukhuselekileyo, ukwakhiwa kwe-anti-static, kunye nokusetyenziswa.
5. Akukho mqobo kwindlela yokufakela kwaye imidiya inokuhamba ngeendlela ezimbini.Ukusetyenziswa kunye nokugcinwa kwe-Intanethi kuluncedo ngakumbi.
Uluhlu loyilo lwevalvu yeplagi yeJLPV luloluhlobo lulandelayo:
1. Ubungakanani: 2 "ukuya kwi-14" DN50 ukuya kwi-DN350
2. Uxinzelelo: Udidi lwe-150lb ukuya kwi-900lb PN10-PN160
3. Izinto eziphathekayo: i-carbon steel, insimbi engenasici kunye nezinye izinto eziqhelekileyo zetsimbi.
I-NACE MR 0175 i-anti-sulfur kunye ne-anti-corrosion metal materials.
4. Uqhagamshelo luphela: ASME B 16.5 kubuso obuphakanyisiweyo (RF), ubuso obuFlat (FF) kunye noLuhlu lweRingi ngokudibeneyo (RTJ）
I-ASME B 16.25 kwisiphelo esikrufu.
5. Imilinganiselo yobuso ngobuso: ihambelana ne-ASME B 16.10.
6. Ubushushu: -29℃ ukuya ku-580℃
Iivalvu ze-JLPV zinokuxhotyiswa nge-gear operator, ii-pneumatic actuators, ii-hydraulic actuators, ii-actuator zombane, ii-bypasses, izixhobo zokutshixa, ii-chainwheels, iziqu ezandisiweyo kunye nezinye ezininzi ziyafumaneka ukuhlangabezana neemfuno zabathengi.
