Soft seal butterfly valve leh hard seal butterfly valve inthlauhna

Hard seal butterfly valve chu a awm a

Butterfly valve hard sealing tih hian sealing pair sir lehlamah metal material emaw hard material dang emaw atanga siam a ni tihna a ni. Hetiang seal hi sealing performance a tha lo hle a, mahse temperature resistance sang tak, wear resistance leh mechanical performance tha tak a nei a ni. Entirnan: thir+thir; Steel+copper hmanga siam; Steel+graphite hmanga siam a ni a; Steel+alloy hmanga siam a ni. Heta steel hi cast iron, cast steel, alloy steel emaw, surfacing leh spray atana hman tur alloy emaw pawh a ni thei.

A seal nem tak chu butterfly valve a nisealing pair sir khat chu thir thil hmanga siam a nih thu leh a sir dang chu elastic non-metallic thila siam a nih thu a sawina a ni. Hetiang seal chi hi sealing performance a tha a, mahse temperature sang takah a do thei lo va, a hak awlsam a, mechanical performance tha lo tak a nei bawk a, chu chu: steel+rubber Steel+PTFE, etc. hmanga siam a ni.

Soft seal seat hi non-metallic material hmanga siam a ni a, a chakna, a khauhna leh a temperature a resistance engemaw zat a awm. Performance tha tak a neih chuan zero leakage a nei thei a, mahse a service life leh temperature nena inmil theihna erawh a tha lo hle. Hard seal hi metal a siam a ni a, sealing performance pawh a tha lo hle. Thil siamtu thenkhat chuan zero leakage a awm thei tih sawi mahse. Soft seal hian corrosive material thenkhat tan process mamawh a phuhruk thei lo. Hard seal hian buaina chu a chinfel sak thei a, heng seal pahnih hi an inzawm khawm thei bawk. Sealing performance chungchangah chuan soft sealing hi a tha tawk viau a, mahse tunah chuan hard sealing sealing performance pawh hian a inmil tur mamawh a phuhruk thei tawh bawk. Soft seal thatna chu sealing performance tha tak a ni a, a that lohna chu a tar awlsam, wear leh service life tawi te a ni. Hard seal hian service life rei tak a nei a, mahse a sealing performance erawh soft seal aiin a chhe zawk hle.

Structural danglamna chu a bik takin hetiang hi a ni:

1. Structural danglamna

Seal nem tak butterfly valve te a awm bawkan tam zawk chu medium line type an ni a, hard seal butterfly valve erawh chu single eccentric, double eccentric leh triple eccentric type an ni tlangpui thung.

2. Temperature laka inven theihna

Soft seal hi temperature pangngaiah hman a ni. Hard seal hi temperature hniam, normal temperature, temperature sang leh hmun dangah te hman theih a ni.

3. Pressure a awm

Soft seal low pressure – normal pressure, hard seal hi hnathawhna hmun, medium leh high pressure-ah pawh hman theih a ni.

4. Sealing hnathawh dan

Soft sealing butterfly valve leh tri eccentric hard sealing butterfly valve te sealing performance hi a tha zawk. Tri eccentric butterfly valve hian pressure sang leh temperature sang tak hnuaiah sealing tha tak a vawng thei a ni.

A chunga kan sawi tak zia te hi thlirin, aa sealing nêm tak butterfly valveventilation leh dust removal pipeline, tui thianghlim, light industry, petroleum, chemical industry leh industry dangte kawng hnih-a hawn leh khar leh siamremna atan a tha hle. Hard sealing butterfly valve hi heating, gas supply, gas, oil, acid leh alkali environment atan te hman a ni ber.

Butterfly valve hman tam tak a nih avangin a features, installation awlsam tak, enkawl awlsam leh structure awlsam tak te chu a langsar zual sauh sauh a ni.Electric hmanga soft seal hmanga siam butterfly valve hmanga siam a ni, pneumatic soft seal butterfly valve, hard seal butterfly valve, etc. te hian electric gate valve, globe valve, etc. te chu a tam zawkin an thlak tan ta a ni.
