Butterfly Valve Structure, Performance Principle leh Classification chungchang hriattirna

I. A tlangpuiinButterfly tih a niValves

Butterfly valve hi valve a ni a, a structure awlsam tak a ni a, flow path a regulate a, a cut off bawk. A key component chu disc ang maia siam butterfly disc a ni a, chu chu pipe diameter lam hawia dah a ni. Valve hi butterfly disc (a tlangpuiin 90°) rotate-in hawn leh khar a ni. A structure compact tak, hawn leh khar chak tak, leh fluid resistance hniam tak a nih avangin industrial field tam takah hman a ni nasa hle.

II. ChumiStructure a niButterfly tih a niValve

Butterfly valve hi a bulpui ber pali atanga siam a ni ber a:

1. Valve taksa: 1.1.Valve shell hi pipeline inzawm nan leh pipeline pressure leh medium load phur nan hman a ni. A tlangpuiin wafer type, flange type leh structure dang a awm thin.
2. Phengphehlepdisc a ni:Valve chhunga core opening leh closing part hi disc ang maia siam a ni. A pianzia (eg, concentric, eccentric) leh a thickness hian valve performance leh flow characteristics a nghawng nghal vek a ni.
3. Valve stem atanga chhuak:Actuator (handel, worm gear emaw electric device ang chi) leh butterfly disc inzawmkhawmtu component. Torque a thawn chhuak a, butterfly disc chu a inher theih nan a khalh bawk.
4. Sealing ring (valve seat) a awm a, chu chu:valve body emaw butterfly disc emaw-a dah elastic element. Valve hi khar a nih chuan butterfly disc sir nen tight seal a siam a, chu chuan medium leakage a veng thei a ni.

Accessories: bearing (valve stem thlawp turin), stuffing box (valve stem-a pawn lam leakage awm loh nan), etc. te pawh a awm bawk.

III. HnathawkPrinciple tih a ni

Butterfly valve hnathawh dan hi a awlsam hle a, butterfly-in a thlawhna a thlawh thlak ang chiah a ni:

Open state-ah chuan:Butterfly plate chu a axis-ah a inher kual vel a. A plane chu medium flow lam hawia parallel a nih chuan valve chu a inhawng kim vek a ni. Hetih lai hian butterfly plate hian medium-ah blocking effect a nei tlem ber a, fluid resistance a tlem a, pressure loss a tlem bawk.

State khar a ni:Butterfly plate chu 90° in a inher chhunzawm zel a. A plane chu medium flow lam hawia perpendicular a nih chuan valve chu a khar vek a ni. Hetih lai hian butterfly plate kil chuan sealing ring chu a press a, seal a siam a, flow path chu a titawp ta a ni.

Adjustment dinhmun: 1.1.Butterfly plate chu 0° leh 90° inkar angle eng pawha dah a nih chuan flow channel-a flow area chu tihdanglam theih a ni a, chu chuan flow rate dik taka siamrem theihna a siam thei a ni.

IV. ChetdanCharacteristics te pawh a awm

Advantage: 1.1.

1. A structure awlsam, a lian lo leh a rit lo: a bik takin installation space tlemte awmna hun atan a tha hle.
2. Quick opening and closing: hawn leh khar zawh nan 90°-a rotate mai la, hman awlsam.
3. Fluid resistance te: A hawn kim chuan valve seat channel effective circulation area a lian zawk a, chuvangin fluid resistance a tlem zawk.
4. A man tlawm: structure awlsam, material tlem zawk, leh siam man hi gate valve leh globe valve specification inang aiin a hniam zawk tlangpui.
5. Flow regulation characteristic tha tak a nei a.

Hmasawnna:

1. Limited sealing pressure: Ball valve leh gate valve nena khaikhin chuan high-pressure condition-a sealing performance hi a chhe deuh hlek a ni.
2. Working pressure leh temperature range tihtlem: sealing ring material temperature leh pressure resistance avanga tihkhawtlai.
3. Particle emaw fiber emaw awmna media atan a tha lo: Solid particle hian sealing surface a ti hrual thei a, sealing effect a nghawng thei bawk.
4. Diameter lian tak butterfly valve-a butterfly plate hian tui lu hloh engemaw zat a siam ang.
