Core Technologies ntawm Tswj Valve Tsim
Tus Qauv Tsim
- Valve Body Type: Select a gate valve, ball valve, or butterfly valve based on the operating conditions. For example, for high-temperature and high-pressure conditions (>500 degree, PN420), forged steel rooj vag li qub yog nyiam, thiab lawv cov phab ntsa thickness yuav tsum tau xam raws li ASME B16.34.
- Flow Characteristics: Cov yam ntxwv ntawm cov kab sib txawv yog tsim rau cov xwm txheej uas muaj qhov sib txawv ruaj khov siab (xws li dej twj tso kua mis tswj), thaum sib npaug feem pua cov yam ntxwv zoo dua rau cov tshuab uas muaj qhov sib txawv loj sib txawv (xws li kev tswj hwm hluav taws xob), nrog rau kev tswj xyuas qhov tseeb ntawm ± 1% FS.
- Sealing Design: Cov ntsaws ruaj ruaj (PTFE) muaj qhov xau tsawg dua lossis sib npaug li 10^-7 m³ / s, thaum cov ntsaws ruaj ruaj (Stelli alloy) tuaj yeem tiv taus kub txog 800 degree, tab sis qhov tseeb machining yuav tsum ncav cuag Ra0.8μm.
Kev xaiv khoom
- Cov khoom siv lub cev muaj xws li WCB carbon steel (-29 ~ 425 degree) thiab CF8M stainless hlau (corrosion resistant). Rau cov ntawv thov supercritical, Inconel 625 (qhov kub thiab txias siab dua lossis sib npaug li 650 degree) yuav tsum tau ua.
- Valve qia cov khoom yuav tsum ua tau raws li cov hauv qab no: tensile zog Ntau dua los yog sib npaug rau 860MPa (xa mus rau ASTM A182), thiab nto tawv chrome plating (50 ~ 100μm thickness) los txhim kho hnav tsis kam.
Cov txheej txheem tsim khoom thiab kev tswj xyuas zoo
1. Precision Machining Technology
- Lub rooj zaum valve sealing nto yog machined siv CNC tig thiab sib tsoo txheej txheem, nrog ib tug roundness yuam kev Tsawg tshaj los yog sib npaug zos rau 0.005mm.
- 3D luam ntawv (SLM thev naus laus zis) ua kom muaj kev sib xyaw ua ke ntawm cov kab ntws nyuaj, txo lub sijhawm xa khoom los ntawm 40% (piv txwv li: GE additive manufacturing tswj valve).
2. Cov qauv ntsuas kev ua haujlwm
- Kev ntsuas dej ntws: ua raws li API 598. Chav VI soft- foob li qub tau tso cai tsawg dua lossis sib npaug rau 3 cua npuas / feeb (nruab nrab: huab cua, siab 0.6MPa).
- Kev Ntsuas Lub Neej: Cov hluav taws xob hluav taws xob yuav tsum dhau 100,000 qhib thiab kaw lub voj voog (MIL-STD-810G), nrog lub zog hloov pauv tsawg dua lossis sib npaug li ± 5%.
Kev Lag Luam Trends thiab Innovation Cases
1. Txawj Ntse Technology
- Ntse li qub nruab nrog IIoT sensors tuaj yeem saib xyuas tus nqi ntws (qhov tseeb ± 0.5%) thiab qhov kub thiab txias ntawm lub sijhawm thiab xa cov ntaub ntawv ntawm Modbus raws tu qauv.
2. Ib puag ncig yuav tsum tau muaj
- Tsawg Emission (TA-Luft tau ntawv pov thawj) li qub xav tau VOC to<50ppm and employ bellows seals or double packing designs.
