Check valve hman chhan chu medium reverse flow venna a ni a, a tlangpuiin pump chhuahna hmunah check valve dah a ni. Hei bakah hian compressor chhuahna hmunah check valve dah tur a ni bawk. A tawi zawngin, medium reverse flow ven nan hmanrua, device emaw pipeline-ah check valve dah tur a ni.
A tlangpuiin vertical lift check valve hi horizontal pipeline-ah hman a ni a, a nominal diameter chu 50mm a ni. Horizontal leh vertical pipeline-ah te straight-through lift check valve dah theih a ni. Bottom valve hi a tlangpuiin pump inlet vertical pipeline-ah chauh dah a ni a, medium chu a hnuai lam atanga chunglam thlengin a luang chhuak thin.
Swing check valve hi working pressure sang takah siam theih a ni a, PN hian 42MPa a thleng thei a, DN pawh lian takin siam theih a ni bawk a, a tam ber chu 2000mm aia tam a thleng thei bawk. Shell leh seal-a thil chi hrang hrang a zirin eng working medium leh working temperature range eng pawhah hman theih a ni. Medium chu tui, steam, gas, corrosive medium, oil, ei tur, damdawi, etc. a ni a, a hnathawhna temperature chu -196~800°C inkar a ni.
Swing check valve dahna hmun hi a tawp lo va, a tlangpuiin horizontal pipeline-ah dah a ni a, mahse vertical pipeline emaw inclined pipeline-ah emaw dah theih a ni bawk.
Butterfly check valve hman hun tur chu pressure hniam leh diameter lian tak a ni a, installation hun pawh a tlem hle. A chhan chu butterfly check valve working pressure hi a sang lutuk thei lo a, mahse nominal diameter hi a lian thei hle a, chu chu 2000mm aia tam a thleng thei a, mahse nominal pressure chu 6.4MPa hnuai lam a ni. Butterfly check valve hi wafer type-ah siam theih a ni a, a tlangpuiin pipeline flange pahnih inkarah wafer connection angin dah a ni.
Butterfly check valve dahna hmun hi a tawp lo va, horizontal pipeline, vertical pipeline emaw inclined pipeline-ah emaw dah theih a ni.
Diaphragm check valve hi pipeline tui hammer awlsam tak tan chuan a tha hle. Diaphragm hian medium reverse flow avanga tui hammer lo awm chu a ti bo thei hle. Diaphragm check valve-te hnathawhna temperature leh operating pressure chu diaphragm material-in a tihkhawtlai avangin, low-pressure leh normal-temperature pipeline-ah te hman a ni tlangpui a, a bik takin tap water pipeline-ah te hman a ni. A tlangpuiin medium hnathawhna temperature chu -20~120°C inkar a ni a, hnathawhna pressure chu 1.6MPa aia tlem a ni a, mahse diaphragm check valve hian diameter lian zawk a nei thei a, DN sang ber chu 2000mm aia tam a ni thei bawk.
Diaphragm check valve hi tun hnaiah waterproof performance tha tak, structure awlsam tak leh siam man tlawm tak a nih avangin hman a ni nasa hle.
Ball check valve hian sealing performance tha tak, rintlak tak leh water hammer resistance tha tak a nei a, a chhan chu seal hi rubber-a khuh sphere a nih vang a ni tin, seal chu ball pakhat emaw, ball tam tak emaw a nih theih avângin, a diameter lian takah siam theih a ni bawk . Mahse, a seal chu rubber-a khuh hollow sphere a ni a, hei hi high-pressure pipeline atan a tha lo va, medium leh low-pressure pipeline tan chauh a tha.
Ball check valve-a shell material hi stainless steel a siam theih a nih avangin, seal-a hollow sphere chu PTFE engineering plastic hmanga khuh theih a nih avangin, general corrosive media nei pipeline-ah pawh hman theih a ni.
Hetiang check valve chi hrang hrang hnathawhna temperature hi -101~150°C inkar a ni a, nominal pressure chu ≤4.0MPa a ni a, nominal diameter range chu 200~1200mm inkar a ni.
