Valve hi industrial piping system-a thil pawimawh tak a ni a, thil siam chhuahna kawngah pawh hmun pawimawh tak a chang a ni.
I. Valve hnathawh ber chu
1.1 Media thlak leh tihtawp dan:gate valve a ni, butterfly valve a ni, ball valve thlan theih a ni a;
1.2 Medium backflow lo awm tur venna:check valve a nithlan theih a ni a;
1.3 Medium pressure leh flow rate siamrem: optional shut-off valve leh control valve;
1.4 Media then hran, mix emaw sem darh dan: plug valve, .gate valve a ni, control valve thlan theih a ni a;
1.5 Pipeline emaw hmanrua emaw him taka a thawh theih nan medium pressure chu a value tarlan aia tam lo turin ven: safety valve thlan theih a ni.
Valve thlan dan hi harsatna awm lo taka hnathawh leh economy lam atanga thlir a ni ber.
II. Valve hnathawh dan
Thil pawimawh engemaw zat a tel a, chungte chu chipchiar taka sawihona chu hetiang hi a ni:
2.1 Conveying fluid awm dan
Fluid Type: Fluid chu liquid, gas emaw vapor emaw a nih pawhin valve thlan dan a nghawng nghal vek a ni. Entirnan, liquid-ah chuan shut-off valve a ngai thei a, gas erawh chu ball valve atan a tha zawk thei thung. Corrosiveness: Corrosive fluids hian corrosion-resistant materials, stainless steel emaw special alloy emaw a mamawh a. Viscosity: Viscosity sang fluid-ah chuan clogging tihziaawmna turin diameter lian zawk emaw, a bik taka siam valve emaw a ngai thei. Particle awm zat: Solid particle awmna fluid-ah chuan wear-resistant material emaw, a bik taka siam valve emaw, pinch valve ang chi emaw a ngai thei.
2.2 Valve hnathawh dan
Switch control: Switching function chauh mamawhna hun atan ball valve emawgate valve te a awm bawkduhthlanna tlanglawn tak an ni.
Flow Regulation: Flow control dik tak a ngai a nih chuan globe valve emaw control valve emaw hi a tha zawk.
Backflow venna: 1.1.Valve te chu enfiah thin ang chefluid backflow venna atan an hmang thin.
Shunt or Merge: Three-way valve emaw multi-way valve emaw hi diverting emaw merging emaw atan hman a ni.
2.3 Valve lian leh te
Pipe Size: Valve size chu pipe size nen a inmil tur a ni a, chutiang chuan fluid kal tlang tur a ni. Flow mamawh: Valve lian leh te hian system flow mamawh a phuhruk a ngai a, a lian lutuk emaw, a te lutuk emaw chuan efficiency a nghawng dawn a ni. Installation Space: Installation space a tlem avangin valve size thlan danah nghawng a nei thei.
2.4 Valve-a resistance hloh
Pressure drop: Valve hian system efficiency a nghawng loh nan pressure drop a tih tlem tur a ni.
Flow channel design: Full bore valve, full bore ball valve ang chi te hian drag loss a ti tlem a.
Valve Type: Valve thenkhat, butterfly valve ang chi te hian hawn a nih chuan resistance a nei tlem zawk a, hei vang hian low pressure drop occasion atan a tha hle.
2.5 Valve hnathawhna temperature leh hnathawhna pressure
Temperature range: Valve material te hi fluid temperature nena inmil tura siam a ngai a, temperature-resistant material te chu temperature sang emaw hniam emaw hmuna thlan a ngai bawk.
Pressure level: Valve hian system hnathawhna pressure sang ber a tuar thei tur a ni a, high-pressure system chuan pressure level sang tak nei valve a thlang tur a ni.
Temperature leh pressure inzawmkhawm: Temperature sang leh pressure sang tak awmna hmunah chuan material chakna leh sealing property te ngaihtuah bik a ngai a ni.
2.6 Valve siamna atana hman tur thil
Corrosion resistance: Fluid corrosiveness a zirin thil tha thlang rawh, chu chu stainless steel, Hastelloy, etc. te hi a ni.
Mechanical strength: Valve material hian hnathawhna pressure tuar thei tur khawpa mechanical strength a neih a ngai a ni.
Temperature adaptability: Material chu hnathawhna temperature nena inmil tur a ni a, temperature sang takah chuan heat-resistant material a mamawh a, temperature hniam takah chuan cold-resistant material a mamawh bawk.
Economy: Performance mamawh phuhrukna tur ngaihtuahin economy tha zawk nei materials thlang rawh.
