Butterfly valve hriatna chungchang sawihona

Kum 30 chho vel khan...butterfly valve a niUnited States-a siam chhuah a ni a, kum 50 chho vela Japan ramah rawn luhtir a ni a, kum 60 chho vela Japan ramah pawh hman a ni nasa hle a, kum 70 chho vela China ramah pawh a lar chho ta a ni. Tunah hian khawvela butterfly valve DN300 mm aia sang te chuan gate valve te chu an thlak zauh zauh tawh a ni. A nena khaikhin chuangate valve te a awm bawk, butterfly valve te hian hawn leh khar hun tawi te, operating torque te, installation space te leh rit lo te an nei bawk. DN1000 entirnan la ila, butterfly valve hi 2T vel a ni a, gate valve hi 3.5T vel a ni a, butterfly valve hi driving device hrang hrang nena inzawm awlsam a ni a, a chhe thei lo a, a rintlak hle bawk.

Rubber seal a chhiatna chubutterfly valve a nichu throttling atana hman a nih chuan hman dik loh avangin cavitation a awm ang a, chu chuan rubber seat chu a ti hring chhuak ang a, a tichhia ang. Tun hnaiah China pawhin metal sealed butterfly valve a siam chhuak bawk a, tun hnaiah Japan pawhin comb ang chi butterfly valve cavitation resistance, vibration hniam leh ri hniam tak tak a siam bawk.

General sealing seat hi rubber tan kum 15-20 chhung a ni a, metal tan chuan kum 80-90 chhung a ni a, a awm dan pangngaiah chuan. Mahse, dik taka thlan dan tur chu hnathawhna hmuna thil tul danah a innghat a ni.

A hawnna inzawmna chu abutterfly valve a nileh flow rate chu a bul berah chuan linear leh proportional a ni. Flow rate control nan hman a nih chuan a flow characteristic pawh hi piping flow resistance nen a inzawm tlat a, chu chu pipeline pahnih a valve dah te diameter leh form a inang a, pipeline loss coefficient pawh a danglam a, valve flow rate pawh a danglam hle ang.

Valve chu throttling lian tak a nih chuan valve plate hnunglam chu cavitation a awm awlsam a, valve a tihchhiat theihna a awm a, chuvangin 15° pawnah hman a ni tlangpui.

Butterfly valve chu middle opening-ah a awm chuan, opening shape siam chu avalve a nibody leh butterfly plate hmalam tawp chu valve shaft-ah a laiah a awm a, a sir lehlamah chuan state hrang hrang a siam a, a sir khatah butterfly plate hmalam tawp chu tui luang lam hawiin a kal a, a sir lehlamah chuan tui luang lam hawiin a kal a, chuvangin, a sir khatah valve body leh valve plate chuan nozzle ang maia hawnna a siam a, a sir lehlamah chuan throttle hole ang maia inhawng, nozzle nen a inang a ni side hi throttle side aiin a chak zawk hle a, negative pressure chu throttle side valve hnuaiah a lo chhuak ang a, rubber seal pawh a tla fo bawk.

Butterfly valve operating torque, valve hawn leh hawn dan inang lo avang hian a hlutna a danglam a, horizontal butterfly valve, a bik takin large-diameter valve, tui thuk avang hian valve shaft lu chunglam leh hnuai lam inthlauhna avanga torque lo chhuak chu ngaihthah theih a ni lo. Chu bakah, valve inlet lamah elbow dah a nih chuan deflection flow a lo awm a, torque a sang chho bawk.
