Sealing hi leakage venna atan a ni a, leakage venna atang hian valve sealing principle pawh zirchian a ni bawk. Sealing performance tichhe thei thil tam tak a awm abutterfly valve te pawh a awm, a bik takin a hnuaia mite hi a huam tel a ni:
1. Sealing siam dan
Temperature emaw sealing force emaw inthlak danglamna hnuaiah chuan sealing pair structure a danglam ang. Chubakah, he inthlak danglamna hian sealing pairs inkara force a nghawng ang a, a tidanglam ang a, chu chuan valve sealing performance a ti tlem ang. Chuvangin seal i thlan dawnin elastic deformation nei seal i thlang ngei ang. Chutih rual chuan sealing surface thickness pawh ngaihven bawk ang che. A chhan chu sealing pair contact surface chu a inmil kim theih loh vang a ni. Sealing surface-a contact surface zau zawng a san chuan sealing atana force mamawh chu a pung a ni.
2. Sealing surface-a pressure bik
Sealing surface-a pressure bik hian sealing performance ofbutterfly valve a nileh valve service life te a ni. Chuvangin, sealing surface-a specific pressure pawh hi thil pawimawh tak a ni. Chutiang dinhmunah chuan specific pressure sang lutuk chuan valve a tichhia ang a, mahse specific pressure tlem lutuk chuan valve leakage a thlen thung. Chuvangin, design kan siam dawnin pressure bik hi a dik leh dik loh kan ngaihtuah kim a ngai a ni.
3. Medium taksa lam thil (physical property) te
Medium physical property hian sealing performance of a nghawng bawkbutterfly valve a ni. Heng physical property te hi a chunglam temperature, viscosity, leh hydrophilicity te bakah a dangte a ni. Temperature inthlak danglamna hian sealing pair slackness leh parts size inthlak danglamna a nghawng mai bakah gas viscosity nen pawh inzawmna inzawm tlat a nei bawk. Gas viscosity hi temperature sang leh tlahniam chuan a sang emaw a tlahniam emaw a ni. Chuvangin, temperature-in valve sealing performance a nghawng tlem theih nan sealing pair kan design dawnin elastic valve seat ang chi thermal compensation nei valve angin kan design tur a ni. Viscosity hi fluid permeability nen a inzawm a ni. Condition inang hnuaia a awm chuan viscosity a san chuan fluid chu a penetrating ability a tlem zawk thin. A chunglam hydrophilicity vangin metal surface-ah film a awm chuan film chu paih chhuah tur a ni. He oil film te tak te avang hian a chunglam hydrophilicity a tichhia ang a, chu chuan fluid channel a tikhawlo ang.
4. Sealing pair quality tha tak a ni
Sealing pair quality hian a awmzia ber chu material thlan dan, matching leh manufacturing dikna kan enfiah a ngai a ni. Entirnan, valve disc hi valve seat sealing surface nen a inmil tha hle a, hei hian sealing performance a ti tha thei hle.
Valve leakage hi nunna leh siamchhuahnaah a tam hle a, chu chuan bawlhhlawh a thlen thei emaw, nunna atana hlauhawm a thlen thei a, chu chu tap tui valve leak te, leh a rah chhuah pawi tak tak, toxic, harmful, flammable, explosive leh The leakage of corrosive media, etc., is a serious threat to personal safety, property safety and environmental pollution accidents. Environment hrang hrang a zirin seal tha tak tak thlang la, characteristic hmang rawh.
