Qhov ntau tshaj plaws kev khiav hauj lwm ntau ntawm cov pob li qub sib txawv ntau ntau, nyob ntawm cov khoom siv, qauv, thiab qauv kev lag luam. Cov hauv qab no yog cov kev faib tawm tseem ceeb (siab: MPA):
1. General siab faib tawm thiab cov ntawv thov raug
Tsawg -} qhov siab pob valve (tsawg dua los yog sib npaug rau 1.6 mpa)
Cov dej hauv pej xeem thiab HVAC: Brass / nrum hlau ntab li qub, siab tshaj plaws 1.6 mpa;
Threaded me -} bore bore li cas pob khoom li DN50, haum rau kev ntsuas tsawg dua lossis sib npaug rau 1.6 mpa.
Nruab Nrab -} Siab pob Valve (1.6-10 MPa)
Kev tswj cov xa hluav taws xob: Q41F Series Stainless Hlau Flange Pob Pob, Nominal Siab 2.5-4.0 MPA (Test Hill txog 3.8 MPA);
Cov Txheej Txheem Tshuaj Txheej Txheem: 304 flanged pob li qub, siab kuj 10 mpa, haum rau kua qaub thiab alkaline. Siab - siab pob valve (10-50 MPA)
Roj thiab roj Pipelines: 316 Stainless Hlau Taub Qab- Weld Pob Rating 1500 Lbf-3000 LBF (sib haum rau 25-50 MPA);
Cov Khoom Siv Zog: Cov Cwj Meem Cog Boiler Fegwater Valve, Tsim Kev Tsim Nyog Siab 42 Mpa (Tshwj Xeeb Foob Yuav Tsum Tau).
Ultra-High-Pressure Customized Ball Valve (>50 mpa)
Cov Ntawv Siv Tshwj Xeeb: Pneumatic High - h siab pob valve tuaj yeem kho nyob rau hauv lub peev xwm ntawm 400-700 kg (kwv yees li 40-70 mpa) rau viscous media lossis cov ntawv thov koom nrog hais.
2. Tub ntxhais kawm tsis muaj kev txwv
Khoom Siv Zog:
304 Stainless hlau muaj qhov siab tshaj plaws kev ntsuam xyuas ntawm tsawg dua lossis sib npaug nrog rau 50 MPA vim nws cov ntsiab lus molybdenum.
Brass valve lub cev muaj lub siab txwv ntawm 0.8 MPa (tsawg dua ib - Thib peb tias cov hlau stainless). Txoj kev sib txuas Txoj Kev cuam tshuam:
Flanges / Welds txhawb kev kub siab (ntau dua los yog sib npaug rau 10 MPa), thaum cov xov muaj tsawg rau cov nyiaj tsawg (tsawg dua lossis sib npaug rau 1.6 MPA).
Sealing thev naus laus zis sib txawv:
PTFE cov ntsaws ruaj ruaj yog tsim nyog rau kev ntsuas tsawg dua lossis sib npaug rau 10 MPa, thaum cov ntsaws ruaj ruaj dua li 42 mpa txwv.
