Block valve hman tlanglawn ber pawl a ni. A that lohna chu a size a lian a, a structure chu globe valve aiin a buaithlak zawk a, a sealing surface pawh a hak a awlsam a, a enkawl pawh a awlsam lo. A tlangpuiin throttling atan a tha lo. Gate valve stem-a thread awm dan azirin chi hnih ah then a ni a, open rod type leh dark rod type te an ni. Gate structural characteristics a zirin chi hnih ah then theih a ni a, wedge type leh parallel type te an ni.
3 Valve enfiah rawh
Check valve hi valve a ni a, chu chuan fluid backflow chu a veng thei a ni. Check valve-a valve flap chu fluid pressure action hnuaiah a inhawng a, chu fluid chu inlet side atanga outlet side-ah a luang chhuak a ni. Inlet lam a pressure chu outlet lam aiin a hniam chuan valve flap chu fluid pressure danglamna, a gravity leh thil dangte action hnuaiah automatic in a khar ang a, chu chuan fluid chu hnunglam a luang lo ang. A structure ang chuan lift check valve leh swing check valve-ah then theih a ni. Lift type hian swing type aiin sealing performance a nei tha zawk a, fluid resistance a nei lian zawk bawk. Pump suction pipe suction port atan chuan a hnuai lam valve thlan tur a ni. A hnathawh chu pump start hmain pump inlet pipe-ah tui a khat a; pump tihtawp hnuah inlet pipe leh pump body chu tuiin a khat vek tur a ni a, chutiang chuan restart leh tura inbuatsaih theih nan. 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.
4 Globe valve hmanga siam a ni
Globe valve hi hnuai lam hawia khar valve a ni a, a hawnna leh khar member (valve) chu valve stem-in a khalh a, valve seat (sealing surface) axis-ah a chho leh chho a ni. Gate valve nena khaikhin chuan adjustment performance tha tak, sealing performance tha lo, structure awlsam, siam leh enkawl awlsam, fluid resistance lian tak leh man tlawm tak a nei a ni.
5 Ball valve a ni
Ball valve hawnna leh kharna hmun chu sphere, circular through hole nei a ni a, chu sphere chu valve stem nen a inher a, valve hawn leh khar dan chu a takin a hriat theih a ni. Ball valve hi a structure awlsam tak, switching chak tak, hman awlsam, size te, light weight, part tlemte, fluid resistance te, sealing performance tha tak leh maintenance awlsam tak a nei a ni.
6 Throttle valve hmanga siam a ni
Throttle valve structure hi a bul berah chuan valve disc tih loh chu globe valve nen a inang vek a ni. Valve disc hi throttling component a ni a, a pianzia hrang hrang hian mizia hrang hrang a nei a. Valve seat diameter hi a lian lutuk tur a ni lo, a chhan chu a hawnna san zawng a tlem vang a ni. Medium flow rate a sang a, chuvangin valve disc erosion a ti chak. Throttle valve hian dimension te tak te, a rit lo a, adjustment performance tha tak a nei a, mahse adjustment accuracy erawh a sang lo.
7 Valve chu plug rawh
Plug valve hian plug body through hole nei chu hawnna leh khar nan a hmang a, plug body chu valve stem nen a inher a, valve hawn leh khar dan chu a hrethiam ta a ni. Plug valve hian a thatna chu a structure awlsam, switching rang, hman awlsam, fluid resistance te tak te, part tlemte leh light weight a nei a ni. Straight-through, three-way leh four-way plug valve a awm bawk. Straight-through plug valve hmangin medium chu cut off a ni a, three-way leh four-way plug valve hmangin medium kalna tur thlak emaw, medium then emaw a ni.
8 Diaphragm valve hmanga siam a ni
Diaphragm valve hawnna leh khar na chu rubber diaphragm a ni a, chu chu valve body leh valve cover inkar ah sandwiched a ni. Diaphragm lai tak atanga chhuak chu valve stem-ah dah a ni a, valve taksa chu rubber hmanga lined a ni. Medium hi valve cover chhungril cavity-ah a luh loh avangin valve stem hian stuffing box a mamawh lo. Diaphragm valve hian structure awlsam tak a nei a, sealing performance tha tak a nei a, enkawl awlsam a ni a, fluid resistance pawh a tlem hle. Diaphragm valve te hi weir type, straight-through type, right-angle type leh direct-flow type ah then a ni.
