pamiyaliwa ning soft seal butterfly valve ampo ing hard seal butterfly valve

Hard seal butterfly valve

Ing hard sealing ning butterfly valve mangabaldugan yang adwa nang gilid ning sealing pair gawa la keng metal o aliwang matigas a materyales. Ing sealing performance na niting klasing seal e ya masanting, pero atin yang matas a temperature resistance, wear resistance ampo masanting a mechanical performance. Alimbawa: bakal+bakal; Bakal+tansu; Bakal+grapito; Bacero+alloy steel. Ing bakal keni malyari ya namang maging cast iron, cast steel, alloy steel o alloy para keng pamag-surface ampo pamag-spray.

malambut a seal butterfly valve

Ing malambut a seal ning butterfly valveing metung a gilid ning sealing pair gawa ya keng metal a materyales, at ing metung a gilid gawa ya keng elastic a e metal a materyales. Ing sealing performance na niting klasing seal masanting ya, pero ali ya resistant keng matas a temperatura, madali yang isulud, ampo atin yang e masanting a mechanical performance, antimo: bakal+goma; Bakal+PTFE, atbp.

Ing soft seal seat gawa ya keng e metal a materyales a ating sikanan, katatagan ampo temperature resistance. Nung masanting ya ing performance, ala yang leakage, pero ing kayang service life ampo ing kayang adaptability keng temperatura medyu mababa ya. Ing hard seal gawa ya keng metal, at ing pamag-seal medyu mababa ya. Agyang deng mapilan a manufacturers sasabyan da na zero leakage ing malyari. Ing malambut a seal e ya makatupad kareng requirements ning prosesu para kareng mapilan a corrosive a materyales. Ing hard seal malyari yang makasolve keng problema, at deng adwang seal a reni malyari lang mipagkalub king metung at metung. Nung tungkul ya keng pamag-seal, ing malambut a pamag-seal medyu masanting ya, pero ngeni ing pamag-seal ning hard sealing malyari na namang akit ing katumbas a requirements. Ing advantage ning soft seal yapin ing masanting a pamag-seal, kabang ing disadvantages yapin ing madaling pamag-aging, wear ampo makuyad a service life. Ing hard seal atin yang makabang bie, pero ing kayang pamag-sealing mas malala ya kesa keng soft seal.

Ing pamiyaliwa da reng istruktura ilapin deng makatuki:

1. Pamiyaliwa king istruktura

Soft seal butterfly valveskeraklan medium line la, kabang deng hard seal butterfly valves keraklan single eccentric la, double eccentric la ampo triple eccentric la.

2. Temperature resistance

Ing malambut a seal magagamit ya keng normal a temperatura ning kapaligiran. Ing hard seal malyari yang gamitan keng mababang temperatura, normal a temperatura, matas a temperatura ampo aliwa pang kapaligiran.

3. Pressure

Soft seal low pressure – normal pressure, hard seal malyari ya namang gamitan keng obra antimo ing medium ampo high pressure.

4. Pamag-seal

Mas masanting ing pamag-seal ning soft sealing butterfly valve ampo ing tri eccentric hard sealing butterfly valve. Ing tri eccentric butterfly valve malyari yang manatili keng masanting a sealing keng matas a pressure ampo matas a temperatura ning kapaligiran.

keng pamaningat kareng katangian babo, ingsoft sealing butterfly valvemasanting ya para keng adwang dalan a pamagbukas ampo pamagsara ampo pamag-adjust kareng bentilasyon ampo pamaglako alikabuk a pipeline, pamag-treat ning danum, light industry, petrolyo, chemical industry ampo aliwa pang industriya. Ing hard sealing butterfly valve keraklan gagamitan de para keng pamagpainit, gas supply, gas, oil, acid ampo alkali a kapaligiran.

Uling keng malawak a pamangamit ning butterfly valve, deng katangian na ning manyaman a pamag-install, manyaman a pamag-maintain ampo ing simpleng istruktura maging yang mas malino.Electric soft seal butterfly valves, pneumatic soft seal butterfly valves, hard seal butterfly valves, atbp. magumpisa na lang palitan deng electric gate valves, globe valves, atbp. keng mas marakal a okasyun.
