Lub valve hom thiab cov tsis tseem ceeb ntawm super siab siab valve thiab fittings Kaifeng siab siab valve tshiab technology innovation siab

Qhov no ntawm JB / T 1308 qhia txog hom thiab qhov tseem ceeb ntawm cov li qub nrog nominal siab PN2500. Qhov no yog tsim rau forging steel li qub nrog nominal siab ntawm PN2500, nominal loj ntawm DN3 ~ DN25, nruab nrab ntawm ethylene, polyethylene thiab lwm yam uas tsis yog-corrosive xov xwm. 2.1 Hom thiab qhov tseem ceeb ntawm lub valve yuav tsum tau teev nyob rau hauv Table 1. 2.2 Qhov kev tso cai ua haujlwm siab ntawm lub valve ntawm qhov sib txawv ntawm kev ua haujlwm kub yog raws li teev hauv Table 2…

Qhov no ntawm JB / T 1308 qhia txog hom thiab qhov tseem ceeb ntawm cov li qub nrog nominal siab PN2500.
Qhov no yog tsim rau forging steel li qub nrog nominal siab ntawm PN2500, nominal loj ntawm DN3 ~ DN25, nruab nrab ntawm ethylene, polyethylene thiab lwm yam uas tsis yog-corrosive xov xwm.
Hom thiab parameters
2.1 Hom thiab qhov tseem ceeb ntawm lub valve yuav tsum tau teev nyob rau hauv Table 1.
Table 1 Valve hom thiab cov yam ntxwv tseem ceeb
2.2 Qhov tso cai ua haujlwm siab ntawm lub valve ntawm qhov sib txawv ua haujlwm kub yuav tsum tau teev nyob rau hauv Table 2.
Table 2 Ua haujlwm siab
Thaum kawg ntawm Lub Xya hli ntuj los ntawm Henan Kaifeng siab siab valve Co., LTD., kawm tau hais tias ib zaug nyob rau hauv lub domestic ntau tshaj 10 valve tuam txhab uas muag mus sim ntau lawm tab sis tsis tau ua tiav high-tech khoom rau loj chav turbine siab regulator, ** nyob rau hauv lub tuam txhab cov neeg ua haujlwm nyob rau hauv kev sib koom ua ke ntawm kev sib raug zoo ntawm localization, Thiab rau lub teb chaws tseem ceeb enterprise Shanghai chav turbine Hoobkas thiab lwm yam lag luam muab ib tug xov tooj ntawm batch ntawm cov khoom. Qhov no ua rau qhov xwm txheej ntawm cov khoom zoo sib xws hauv tsev tag nrho nyob ntawm kev xa khoom los ua keeb kwm. Cov khoom siv high-tech no kuj tau dhau los ua qhov kev loj hlob ntawm kev lag luam tshiab ntawm Kaigao lub tuam txhab tom qab kev txhim kho zoo ntawm P91, P92 thiab lwm yam tshwj xeeb li qub, lub tuam txhab tam sim no ua cov khoom siv tshiab, thiab siv zog ua kom tiav ntau dua hauv high-tech valve. industrialization, tuav thawj lub khw.

Nws tau tshaj tawm tias lub tuam txhab tsis ntev los no tau tsim lub siab tswj lub valve feem ntau yog siv hauv chav turbine ntawm lub tshuab hluav taws xob teeb. Kev tsim cov khoom lag luam no suav nrog cov thev naus laus zis nyuaj xws li kev teeb tsa kub, kub vuam thiab titanium ntsug hluav taws xob vuam (vuam nrog tungsten thiab cobalt hard alloy electrodes). Ntau lub tuam txhab lag luam hauv tsev tau siv zog rau qhov kev hwm no, tab sis txhua yam ua tsis tiav, thiab Tuam Tshoj cov tuam txhab loj turbine yuav tsum vam khom cov khoom lag luam zoo li no. Kaigao lub tuam txhab yog nyob rau hauv lub concentration ntawm internal technical force, tom qab kev siv zog los txhim kho kev vam meej, thiaj li mus ua ib tug domestic valve tuam txhab muaj peev xwm tsim tau hom high-tech khoom ntawm lub enterprise, nws cov khoom nqi * rau ntshuam nqi ntawm txog 50. %, kev lag luam zeem muag yog dav heev. Lub tuam txhab tau tsim cov khoom siv thiab kev lag luam kev koom tes nrog ntau lub chaw ua haujlwm turbine, thiab kos npe cog lus nrog ob lub tuam txhab txawv teb chaws los ua nws cov tuam txhab txhawb nqa hauv Suav teb.
