Check valve hnathawh dan
Chumicheck valve a ni pipeline system-ah hman a ni a, a hna ber chu medium backflow, pump leh a khalhtu motor reverse rotation leh container chhunga medium discharge te ven hi a ni.
Valve te chu enfiah thin ang che auxiliary system supply tu line-ah pawh hman theih a ni a, chutah chuan pressure chu main system pressure aia sangin a sang thei a ni. Check valve hi thil chi hrang hrang angin media hrang hrang pipeline-ah hman theih a ni.
Check valve hi pipeline-ah dah a ni a, pipeline pum puia fluid component pakhat a lo ni ta a ni. Valve disc hawn leh khar dan hi a awmna system-a transient flow state-in a nghawng a; in turn, the closing characteristics of the valve disc are Fluid flow state-ah nghawng a nei a ni.
Valve classification enfiah rawh
Swing check valve disc hi disc ang chi a ni a, valve seat channel shaft vel a inher kual a ni. Valve chhunga channel chu a streamline avangin lift check valve aiin flow resistance a tlem zawk a ni. Flow rate hniam leh flow inthlak danglam fo lo tan a tha hle. Mahse, pulsating flow atan a tha lo a, a sealing performance pawh lifting type angin a tha lo hle.
Swing check valve hi chi thum-ah then a ni a, chungte chu single-lobe type, double-lobe type leh multi-lobe type te an ni. Heng form pathumte hi valve diameter a zirin an inthen ber a ni.
2. Check valve chu chawi sang rawh
Check valve a ni a, chutah chuan valve disc chu valve body vertical centerline-ah a slide a. Lift check valve hi horizontal pipeline-ah chauh dah theih a ni a, high-pressure small-diameter check valve-a valve disc atan ball hman theih a ni bawk. Lift check valve valve body shape hi globe valve nen a inang (globe valve nen hian hman dun theih a ni), chuvangin a fluid resistance coefficient chu a lian zawk a ni. A insiam dan chu globe valve nen a inang a, a valve body leh disc hi globe valve nen a inang a ni.
Check valve a ni a, chutah chuan disc chu seat chhunga pin pakhat vel a inher kual thin. Disc check valve hi a structure awlsam tak a ni a, horizontal pipeline-ah chauh dah theih a ni a, sealing performance pawh a tha lo hle.
4. Pipeline check valve a awm tur a ni
Valve pakhat, a chhunga disc chu valve body centerline-a a tlan kualna. Pipeline check valve thar a ni. A lianin a te a, a rit lo hle a, processing technology lamah pawh a tha hle. Check valve hmasawnna kawng khat a ni. Mahse, fluid resistance coefficient hi swing check valve aiin a lian deuh hlek a ni.
5. Compression check valve a ni
Hetiang valve hi boiler feed water leh steam cut-off valve atan hman a ni a, lift check valve leh globe valve emaw angle valve emaw integrated function a nei a ni.
Tin, pump outlet dahna atana tha lo check valve thenkhat, foot valve, spring type, Y type, etc. te pawh a awm bawk.
