Production Of Gate Valves

Kev taw qhia txog kev tsim cov rooj vag li qub: Cov hauv qab no yog cov lus qhia luv luv rau cov txheej txheem valve, cov txheej txheem ntxaws thiab cov txheej txheem thov xa mus rau peb lub tuam txhab cov kev qhia xov xwm.

• Valve lub cev casting

1. Waxing Rhiav - qauv - kub ciab - txias 2. Plhaub rhiav - nplua xuab zeb - coarse xuab zeb - plhaub ua 3. Wax tshem tawm 4. Roasting 5. Casting 6. xuab zeb tshem tawm, tseem hu ua xuab zeb tshem tawm 7. Polishing tua blasting

Casting kev kho mob

1. Sib tsoo 2. Sandblasting 3. Cam khwb cia hlau, chromium molybdenum hlau, tsis tshua muaj steel hlau (kev kho annealing); Stainless hlau (pickling, tshuaj kho).

• Valve lub cev machining

1. Valve lub cev lub taub hau ua, thiab qhov rooj kho mob 2. Drilling, thim rov qab riam 3. Sealing nto ntxhib tsheb 4. Surfacing welding (surfacing welding txheej txheem rau hard sealed li qub yog ua los ntawm hnav-resistant, corrosion-resistant, hardness yuav tsum tau thiab lwm yam ntaub ntawv. raws li hauv qab no: Hlau, 2Cr13, D507Mo, 304, 316, thiab lwm yam.) 5. Kev sib tsoo loj ntawm lub cev valve thiab txoj kab uas hla 6. Tiav ntawm valve lub cev sealing nto 7. Rough sealing nto ntawm rooj vag disc 8. Surfacing vuam ntawm lub rooj vag thiab disc 9 . Valve disc thiab disc tiav

• Valve npog txhawb kev ua haujlwm

1. Pob valve flange thiab txoj kab uas hla kev ua haujlwm (valve cover seal ob txoj kev, valve cover gate); Kos valve npog txheej txheej gasket ua 2. Rooj vag valve, nres valve bracket lub taub hau 3. Txhawb sealing xov ua 4. Txhawb packing thiab cap xov ua 5. Txhawb 1000kg drilling 6. Txhawb nqa valve qia txiv ntseej muab tub lim

• Kev ua haujlwm

1. Forging puag ncig steel, annealing (lub rooj vag valve ntiaj teb valve) 2. Kev ua haujlwm sab sauv, ya xov thiab ntxuav tawm ntug ( rooj vag valve ntiaj teb valve) 3. Tus pas nrig du deburring ( rooj vag valve globe valve) 4. Flatten hauv qab ntawm lub valve qia kom lub zog ntawm lub rooj vag phaj yog txawm tias 5. Pob valve chav kawm ntxiv rau PTFE gasket thiab O-ring (mos foob chav kawm) 6. Ntxiv rau cov khoom siv hluav taws xob electrostatic thiab lwm yam raws li cov neeg siv khoom xav tau 7. Rooj vag valve, lub ntiaj teb valve qia 4 "forging pib, tag nrho cov qia raug kuaj rau sab sauv 8. Cov txiv ntoo yog hexagonal tooj liab txiv ntoo.

• Kev ntsuas siab los ua ke

1. Lub rooj vag valve 150LB 6 "hauv qab nruab nrog T-hom cap, 6" pib nrog cov kabmob, 8" pib nrog ob chav kabmob, cov cuab yeej bearing cap, thimble, 300LB rooj vag valve 4" pib raws li saum toj no;

2. Tag nrho cov handwheels yog tshuaj tsuag xim, high-end cua;

3. Rau tag nrho cov rooj vag li qub thiab lub ntiaj teb li qub, qhov kev ntsuam xyuas yog 1.5 npaug ntawm lub sealing siab, thiab qhov kev sim sealing yog 1.1 npaug ntawm qhov xav tau sealing siab ntawm lub valve;

4. Txhua lub valve muaj qhov ntsuas ntawm lub foob

• Kev lees txais cov khoom tiav

1. Valve sab nraud lub voj voog, convex, qhov muag nrug ntsuas decompression

2. Tshawb xyuas qhov tshwm sim

3. Valve seal waterline cover tiv thaiv xyuas

4. Tshawb xyuas txhua qhov chaw thiab cov khoom siv ntxiv
