lentrodiksyon bann materyo ki ferm valv—TWS Valve

materyo sele valv i en parti enportan dan sele valv. ki bann materyo ki ferm valv? nou konnen ki bann materyo bag seleksyon valv i ganny divize an de kategori: metal ek non-metal. Sa ki swiv i en pti lentrodiksyon lo bann kondisyon litilizasyon bann diferan materyo sele, osi byen ki bann kalite valv ki ganny servi souvan.

1. Lastik sentetik

bann propriyete konpreansiv lastik sentetik tel ki rezistans delwil, rezistans tanperatir e rezistans korozyon i pli bon ki lastik natirel. zeneralman, tanperatir litilizasyon lastik sentetik i t≤150°C, e tanperatir lastik natirel i t≤60°C. Lastik i ganny servi pou sele bann valv glob,valv laport an lastik, valv dyafragm,rubber seated butterfly valve, rubber seated swing check valve (valv tyeke), pinch valves e lezot valve avek presyon nominal PN≤1MPa.

2. Nilon

nilon i annan bann karakteristik pti koefisyan friksyon e bon rezistans korozyon. Nylon i plizoumwen ganny servi pou bann valv boul ek valv glob avek tanperatir t≤90°C e presyon nominal PN≤32MPa.

3. PTFE

PTFE i ganny servi sirtou pou bann valv glob,valv baro, ball valves, eksetera avek tanperatir t≤232°C e presyon nominal PN≤6.4MPa.

4. feray fonte

feray i ganny servi pouvalv baro, globe valve, plug valve, eksetera pou tanperatir t≤100°C, presyon nominal PN≤1.6MPa, gas ek delwil.

5. Babbitt alloy

alye Babbitt i ganny servi pou valv glob amonya avek tanperatir t-70~150°C e presyon nominal PN≤2.5MPa.

6. alyaj kwiv

bann materyo komen pou bann alyaj kwiv i 6-6-3 bronz tin ek kwiv manganese 58-2-2. alye kwiv i annan en bon rezistans a dega e i apropriye pou delo ek vapeur avek tanperatir t≤200°C e presyon nominal PN≤1.6MPa. i souvan ganny servi danvalv baro, globe valves,valv tyeke, ploge valves, eksetera.

7. feray krom

bann grad stainless steel chromium ki ganny servi souvan i 2Cr13 ek 3Cr13, ki'n ganny tennyen e tanpere, e annan en bon rezistans korozyon. i souvan ganny servi dan bann valv pou medya tel ki delo, vapeur ek petrol avek tanperatir t≤450°C e presyon nominal PN≤32MPa.

8. Lasye inoxydab krom-nikel-titan

grad ki ganny servi souvan pour chromium-nickel-titanium stainless steel i 1Cr18Ni9ti, ki annan en bon rezistans korozyon, rezistans lerozyon e rezistans lasaler. i apropriye pou vapeur, lasid nitrik e lezot medya avek tanperatir t≤600°C e presyon nominal PN≤6.4MPa, servi pou globe valve, ball valve, eksetera.

9. lasye nitride

grad nitride steel ki ganny servi souvan i 38CrMoAlA, ki annan en bon rezistans korozyon e rezistans grate apre tretman karburizasyon. servi souvan dan valv gate stasyon elektrisite avek tanperatir t≤540°C e presyon nominal PN≤10MPa.

10. Boronizing

Boronizing i direkteman proses sirfas sele sorti dan materyo lekor valv oubyen lekor disk, e apre i fer tretman sirfas boronizing, sirfas sele i annan en bon rezistans a dega. servi dan stasyon kouran valv soufle.
