Pangiparungtal na saray materyales ed panagsara na balbula—TWS Valve

Say materyales ya panagsara na balbula et importantin kabiangan na panagsara na balbula. Anto ray materyales ya pangiseal na balbula? Amta tayo ya saray materyales na valve sealing ring et naapag ed duaran kategorya: metal tan aliwan metal. Say onggendan et antikey ya introduksion ed saray kondisyon na pangusar ed nanduruman materyales ya panag-seal, ontan met ed saray kaslakan ya uusaren ya klase na balbula.

1. Sintetikon goma

Say komprehensibon kablian na sintetikon goma a singa say ag-onkulang ed larak, ag-onkulang ed petang tan ag-onkulang ed corrosion et mas maong nen say natural a goma. Diad inkalapagan, say temperatura na pangusar na sintetikon goma et t≤150°C, tan say temperatura na natural a goma et t≤60°C. Say goma et uusaren pian naseal iray balbula na globo,goma ya akayurong ed balbula na gate, diaphragm valves,rubber seated butterfly valve, rubber seated swing check valve (check valves), pinch valves tan arum niran balbula ya walay nominal pressure ya PN≤1MPa.

2. Nylon

Say nylon et walaan na saray katangian ya melag so friction coefficient tan maong ya resistensya ed corrosion. Say nylon et maslak ya uusaren parad ball valves tan globe valves ya walay temperatura ton t≤90°C tan nominal pressure ya PN≤32MPa.

3. PTFE

Say PTFE et maslak ya uusaren parad globe valves,saray balbula na gate, ball valves, tan arum nira ya walay temperatura ton t≤232°C tan nominal pressure ya PN≤6.4MPa.

4. Cast iron

Say cast iron et uusaren paradgate valve, globe valve, plug valve, tan arum ni parad temperatura t≤100°C, nominal pressure PN≤1.6MPa, gas tan larak.

5. Babbitt alloy

Say Babbitt alloy et uusaren parad ammonia globe valve ya walay temperatura ton t-70~150°C tan nominal pressure ya PN≤2.5MPa.

6. Copper alloy

Saray kaslakan ya materyales parad copper alloys et 6-6-3 tin bronze tan 58-2-2 manganese brass. Say copper alloy et walaan na maong ya resistensya ed panag-usar tan matukoy ed danum tan singaw ya walay temperatura ton t≤200°C tan nominal pressure ya PN≤1.6MPa. Mabetbet ya uusaren itan edsaray balbula na gate, globe valves,check valves, plug valves, tan arum nira.

7. Chrome stainless steel

Say kaslakan ya uusaren ya grado na chromium stainless steel et 2Cr13 tan 3Cr13, ya a-quench tan a-temper, tan walaan na maong ya resistensya ed corrosion. Mabetbet ya uusaren iya ed saray balbula parad media a singa say danum, singaw tan petrolyo ya walay temperatura ton t≤450°C tan nominal pressure ya PN≤32MPa.

8. Chromium-nickel-titanium stainless steel

Say kaslakan ya uusaren ya grado na chromium-nickel-titanium stainless steel et 1Cr18Ni9ti, ya walaan na maong ya resistensya ed corrosion, resistensya ed erosion tan resistensya ed petang. Saya so matukoy parad singaw, nitric acid tan arum niran media ya walay temperatura ton t≤600°C tan nominal pressure ya PN≤6.4MPa, ya uusaren parad globe valve, ball valve, tan arum nira.

9. Nitrided steel

Say kaslakan ya uusaren ya grado na nitrided steel et 38CrMoAlA, ya walaan na maong ya resistensya ed corrosion tan resistensya ed gasgas kayari na carburizing treatment. Kaslakan ya uusaren ed power station gate valve ya walay temperatura ton t≤540°C tan nominal pressure ya PN≤10MPa.

10. Boronizing

Say boronizing et direktan manproseso ed sealing surface manlapud materyal na valve body odino disc body, insan to gawaen so boronizing surface treatment, say sealing surface et walaan na maong ya wear resistance. Uusaren ed blowdown valve na istasyon na kuryente.
