Inkqubo yofakelo lwangaphandle lwamaziko oshishino lwehlabathi luyakhawuleza. Ngokwengxelo yonyaka ka-2024 yoMbutho weHlabathi weValve, ngaphezulu kwe-62% yeevalvu zeshishini kufuneka zisebenze kwindawo evulekileyo -ekumoya okanye -evulekileyo-kwindawo zomoya. Ngokukodwa kumasimi asakhulayo anje ngezikhululo zamandla amatsha, ubunjineli baselwandle, kunye nophando lwenzululwazi lwepolar, amavili ezandla zevalvu ajongana nemiceli mngeni emininzi efana nemitha ye-ultraviolet, ukubola kwetyuwa yokutshiza, kunye nokunxiba kwesanti nothuli. I-avareji yobomi benkonzo yamavili ezandla zentsimbi yentsimbi kwiindawo eziselunxwemeni zehle kakhulu ukusuka kwiminyaka eyi-10 ngaphakathi ukuya kwi-2-3 iminyaka ngaphandle, kunyanzeliswa ukuphindaphindwa kobuchwepheshe bezinto eziphathekayo.

2. Uhlalutyo oluthelekisayo lwentsebenzo yemathiriyeli eqhelekileyo

● Iimpawu zezinto zensimbi ezingenasici

I-1.316L i-austenitic stainless steel: ukusebenza okugqwesileyo kwiindawo zaselwandle kunye ne-chloride ion concentrations Ngaphantsi okanye ilingana ne-5000ppm, kunye nobunzima bomhlaba bungafikelela kwi-HV3503 emva kwe-anodizing.

2. I-Bidirectional steel stainless 2205: ukuxhathisa kwe-corrosion yoxinzelelo kunyuke ngama-40%, kwaye isetyenziswe kwizixhobo ze-handwheel ze-oyile kunye negesi kwi-South China Sea.

●Ukuphumelela kwizicelo zeplastiki zobunjineli

1. Reinforced polyamide (PA66+GF30): passed ISO 4892-2 ultraviolet aging test, and the tensile strength retention rate after 5000 hours of irradiation is >85%.

2. I-polyetheretherketone (PEEK): iqondo lokushisa -100℃~ 260℃, ukutshintshwa ngempumelelo kwee-handwheels zentsimbi kwizikhululo zokufumana i-LNG.

3. Isilumkiso somngcipheko: Kusekho umngcipheko wokudumba kwiindawo eziqinileyo zeasidi (pH＜2).

● Ukuziqhelanisa ne-aluminiyam yealloyi ekhaphukhaphu

I-aluminium ye-1.7075 ye-aviation: i-micro - iteknoloji ye-arc oxidation isetyenziselwa ukwenza umaleko we-ceramic we-50μm, kwaye uvavanyo lokutshiza ityuwa ludlula iiyure ezingama-3000.

2. Inzuzo yobunzima: 60% ikhaphukhaphu kunentsimbi yezandla etyhidiweyo yamandla afanayo, alungele iimeko zokusebenza eziphezulu{2}}.

3. Ukukhuselwa kwe-conductive: i-insulating coating layer iyadingeka ukukhusela i-electrolytic corrosion.

● Iintsingiselo ezintsha kwizinto ezihlanganisiweyo

3. Imiba ephambili yokukhethwa kwiimeko ezinzima

●Isicwangciso sokuphendula kwimidiya ebolileyo

1. C4 level corrosion environment (ISO 12944): Kuyacetyiswa ukuba kusetyenziswe i-nickel{3}}based alloy 625 handwheel, enezinga lokutya lonyaka<0.01mm

2. I-Acid{1}}iimeko zokusebenza ezitshintshanayo ezisisiseko: Kukhethwa i-Hastelloy C-276, enoluhlu lokunyamezela pH 0-14.

● Uvavanyo lokunyamezela utshintsho olugqithisileyo

1. Umceli mngeni wobushushu obuphantsi: I-polytetrafluoroethylene (PTFE) i-Modified handwheels kufuneka isetyenziswe kwindawo ye--60℃ukuze kugcinwe ukuqina kwaye kungabi brittle.

2. Imilinganiselo yokushisa ephezulu: I-316 i-handwheels yensimbi engenasici kufuneka ixhotyiswe nge-graphite lubrication system phantsi kweemeko zokusebenza ze-400.

● Umthamo wokuthwala umthwalo womatshini

1. Torque matching: DN200 valves are recommended to have a handwheel diameter of ≥400mm and an output torque of >300N.

●Anti{0}}i-ultraviolet eguga index

1. Uvavanyo olukhawulezayo lokuguga: Iphumelele i-QUV I-handwheel ihlolwe iiyure ezingama-3000 kwaye inobomi benkonzo yangaphandle engaphezu kweminyaka eyi-8.

2. Unyango lomphezulu: I-Ceramic coating inokunyusa ukukhanya kwe-UV ukuya kwi-92%.

4. Uhlalutyo lwemeko yesicelo esiqhelekileyo

● Iyunithi yokuqhekeka yecatalytic yendawo yokusulungekisa isebenzisa amavili esandla entsimbi ephindwe kabini, ebesoloko eqhuba iminyaka emi-5 kwimo yesulfure{1}equlathe i-oyile nerhasi ngaphandle kweempawu zomhlwa. Iiparamitha eziphambili:

1. Ubushushu obuphakathi: 280-400 degree

2. Uxinzelelo lwe-H2S: 5000ppm

3. Umjikelo wesondlo: wandiswa ukuya kwiinyanga ezili-181

● Ukuchasana{0}nokonakalisa umhlwa kumaqonga akude nonxweme

I-Oyile yoLwandle lwase-China kunye negesi yegesi ithathe indawo ngokupheleleyo i-carbon fiber composite handwheels ukuphumeza:

1. Izinga lokudleka kwesitshizi setyuwa lehle ngama-90%.

2. Ugcino lweendleko zolondolozo lwe-2.2 yezigidi zeeyuan/ngonyaka

3. Ixesha lokuphumla elingalindelekanga lincitshiswe ngeeyure ze-150 / iqonga

● Ukuqinisekiswa kokuqina kokusingqongileyo kwentlango

Idatha yovavanyo yesikhululo samandla elanga saseSahara ibonisa:

1. Ubomi bokulwa{1}}nothuli lobunjineli bamavili ezandla zeplastiki yi> 10 iminyaka
