I-China Ehlala Eqinile Yeziqephu Ezintathu Zebhola Eshiselwe Ivalvu Yokuxhumana Okuphephile Nokwethembekile
Le 【Ihlala isikhathi eside】i-valve yebhola eshiselwe izingcezu ezintathu yenziwe ngezinto ezisezingeni eliphezulu ukuze kuqinisekiswe ukusebenza okuzinzile kwesikhathi eside. Izici zayo zokuklama zihlanganisa ukuxhumana okungenamthungo, ukuhlinzeka ngokuphepha okwengeziwe nokuthembeka, okufanelekile ezindaweni ezihlukahlukene zezimboni ezinokhahlo. I-valve yebhola ixhunywe ohlelweni lwamapayipi ngobuchwepheshe bokushisela obunembile, iqinisekisa ukulawulwa koketshezi olusebenzayo nokusebenza okuseqophelweni eliphezulu kokuvala.
Amapharamitha wobuchwepheshe:
- Material: izinga okusezingeni carbon steel noma insimbi engagqwali (304, 316, njll)
- Ingcindezi: 1.6-4.0MPa (ingahluka kuye ngosayizi othize nezinto)
- Izinga lokushisa lokusebenza: -20°C kuya ku-425°C (i-carbon steel), -20°C kuya ku-300°C (insimbi engagqwali)
-Isisetshenziswa esisebenzayo: amanzi, isitimu, uwoyela nezinye izinto ezingagqwali noma ezigqwalile
- Indlela yokuxhuma: uxhumano lwe-welding, oluhlinzeka ngokuhlanganisa okungenamthungo
- Ukucaciswa kobubanzi: DN15-DN300 (ingenziwa ngokwezifiso ngokufunwa)
- Umsebenzi we-valve: nqamula noma ulungise ukugeleza
- Imodi yeDrayivu: ukusebenza okwenziwa ngesandla.
Ukucaciswa nosayizi:
- Usayizi: DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300
- Isamba sobude bevalvu: buyahlukahluka kuye ngobubanzi nosayizi ojwayelekile
- I-torque esebenzayo: emaphakathi, kulula ukuyisebenzisa ngesandla.
Izici zomkhiqizo:
- Okuhlala isikhathi eside: izinto ezihlala isikhathi eside zikhethiwe ukuze kunwetshwe impilo yesevisi ye-valve
- Ukuxhumeka okungenamthungo: uxhumano lwe-welding luthuthukisa amandla nokuvala ipayipi lonke
- Iphephile futhi inokwethenjelwa: ukwakhiwa okuqinile kanye nezinto ezisezingeni eliphezulu zokubeka uphawu kuqinisekisa ukusebenza okuphephile nokuthembeka kwesikhathi eside
- Ukushisa okuphezulu nokucindezela okuphezulu: kulungele izinga lokushisa eliphezulu nezimo zokucindezela okukhulu, ukuhlangabezana nezidingo eziqinile zezimboni.
Izicelo:
Le valve yebhola ifaneleka ngokukhethekile izinhlelo zokusebenza ezidinga ukuthembeka kwesikhathi eside nokuqina okuphezulu, njengezinhlelo zokushisa zasemadolobheni, izitshalo zamandla ashisayo, izitshalo ze-petrochemical nezinye izimboni. Uxhumano lwe-welding olungenamthungo lukwenza kube inketho ekahle yokulawula uketshezi kumazinga okushisa aphezulu nasezindaweni ezinengcindezi ephezulu.
