Sɔm valv dɛn kin inkɔrpɔret di gasket as pat pan dɛn kɔr silin asɛmbli, we dɛn mek fɔ intagret insay di valv strɔkchɔ.

1. Bɔtaflay valv-valv sit gasket

• Di sit fɔ di bɔtaflay valv na rili wan ring gasket, we dɛn kin prɛs insay di insay wɔl na di valv bɔdi ɔ put am rawnd di bɔtaflay disk.
• We di bɔtaflaydiskklos, i de pres di valv sit gasket fכ fכm wan dinamik sil (as di bכtaflaidiskde rɔta).
• Di matirial na tipikli rɔba (ɛgz., EPDM, NBR, Viton) ɔ PTFE, we dɛn mek fɔ akɔmod difrɛn midia ɛn tɛmpracha kɔndishɔn.

2. Bol Valv we yu de yuz-Valv Sit Gasket we yu go si

• di valv sit fכ wan bol valv na wan kayn gasket bak, we dεn kin mek wit mεtirial dεm lεk PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), כ rεinfכs plastic.
• I de gi wan sil bitwin di bɔl ɛn di valv bɔdi, we de sav ɔl tu as statik sil (rilaytiv to di valv bɔdi) ɛn dinamik sil (rilaytiv to di bɔl we de rɔta).

IV. Us valv dɛn nɔ kin yuz wit gasket?

1. Welded valves: Dɛn kin wɛld di valv bɔdi dairekt to di paip, we kin mek dɛn nɔ nid flɛnch ɛn gasket.
2. Valv dɛn we gɛt kɔnɛkshɔn we gɛt trɛd: Dɛn kin yuz trɛd silin (lɛk raw matirial tep ɔ silin), jɔs lɛk ɔltin we kin mek dɛn nɔ nid gasket.
3. Monolitik valv dεm: Sכm lכw kכst bol valv dεm כ spεshal valv dεm gεt wan intagrεd valv bכdi we dεn nכ kin disassemble, so dεn nכ gεt valv kכva gasket.
4. Valv dɛn we gɛt O-ring ɔ gasket dɛn we dɛn rap wit mɛtal: Insay ay-prɛshɔn, ay-tɛmpracha, ɔ spɛshal-midul aplikeshɔn dɛn, advans silin sɔlvishɔn dɛn kin tek ples fɔ kɔmɔn gasket dɛn we nɔ gɛt mɛtal.

V. Sɔmari: .

Valv gasket na wan kayn jenɛral kɔt ki siling ɛlimɛnt, dɛn kin yuz am bɔku bɔku wan na di paip layn kɔnɛkshɔn fɔ difrɛn flɛnch valv dɛn, ɛn dɛn kin yuz am bak fɔ di valv kɔva silin fɔ bɔku valv dɛn. Insay di sɛlɛkshɔn, i nid fɔ pik di rayt gasket matirial ɛn fɔm akɔdin to di kayn valv, kɔnɛkshɔn mɔd, midul, tɛmpracha ɛn prɛshɔn.
