Valve chungchanga practical hriatna

Valve foundation a ni
1. Valve-a parameter bulpui ber chu: nominal pressure PN leh nominal diameter DN te hi a ni
2. Valve hnathawh bulpui: connected medium chu titawp la, flow rate siamrem la, flow direction thlak rawh
3, valve inzawmna kawng lian ber berte chu: flange, thread, welding, wafer
4, valve pressure —— temperature level chuan: material hrang hrang, hnathawhna temperature hrang hrang, maximum allowed no impact working pressure a inang lo tih a tarlang
5. Flange standard-ah hian system lian pahnih a awm a, chungte chu European state system leh American state system te an ni.
System pahnih pipe flange connection hi a danglam vek a, a inmil thei lo;
Pressure level hmanga thliar hran a remchang ber:
European state system chu PN0.25,0.6, 1.0, 1.6, 2.5, 4.0, 6.3, 10.0, 16.0, 25.0, 32.0, 40.0MPa a ni a;
US state system chu PN1.0 (CIass75), 2.0 (CIass150), 5.0 (CIass300), 11.0 (CIass600), 15.0 (CIass900), 26.0 (CIass1500), 42.0 (CIass2500) MPa a ni.
Pipe flange chi hrang hrangte chu: integral (IF), plate flat welding (PL), neck flat welding (SO), neck butt welding (WN), socket welding (SW), screw (Th), butt welding ring loose sleeve (PJ / SE) / (LF / SE), flat welding ring loose sleeve (PJ / RJ) leh flange cover (BL), etc. te an ni.
Flange sealing surface chi hrang hrangah hian a bik takin: full plane (FF), protrusion surface (RF), concave (FM) convex (M) surface, ring connection surface (RJ), etc. te hi a tel a ni.

Valve hman tlanglawn (common) te
1. Valve type code-a Z, J, L, Q, D, G, X, H, A, Y, S te chu a hnuaia mi ang hian tarlan a ni: gate valve, stop valve, throttle valve, ball valve, butterfly valve, diaphragm valve, plug valve, check valve, safety valve, pressure reducing valve leh drain valve te.
2, Valve connection type code 1,2,4,6,7 chuan hetiang hian a sawi: 1-internal thread, 2-external thread, 4-flange, 6-welding, 7-pair clip
3, Valve code 9,6,3-a transmission mode-ah chuan: 9-electric, 6-pneumatic, 3-turbine worm.
4, Valve body material code Z, K, Q, T, C, P, R, V chuan hetiang hian a sawi: gray cast iron, malleable cast iron, ductile cast iron, copper leh alloy, carbon steel, chromium-nickel nickel stainless steel, chromium-nickel-molybdenum stainless steel, chromium-molybdenum vanadium steel.
5, Seat seal emaw lining code R, T, X, S, N, F, H, Y, J, M, W a ni ang: austenitic stainless steel, copper alloy, rubber, plastic, nylon plastic, fluorine plastic, Cr stainless steel, hard alloy, lining rubber, moner alloy, valve body material.

6. Actuator thlan tur hian eng thil pawimawh pathum nge ngaihtuah tur?
1) Actuator output chu regulating valve load aiin a tam tur a ni a, a remchan dan angin a inmil tur a ni.
2) Standard combination enfiah tur chuan regulating valve-in a tarlan allowable pressure difference chuan process mamawh a tlin a ni. Pressure danglamna lian tak awm chhung hian valve core unbalanced force chu chhut tur a ni.
3) Actuator response speed hian process operation, a bik takin electric actuator mamawh a tlin leh tlin loh.
7, TWS valve company hian a pe thei em?
Rubber hmanga thut chu butterfly valve a ni: wafer hnim hring valve, lug hnim hring valve, .flange butterfly valve hmanga siam a ni; gate valve hmanga siam; check valve tih a ni a;balancing valve a ni, ball valve, etc. te a ni.
Tianjin Tanggu Water Seal Valve Co., Ltd. ah hian industry standard sang ber nena inmil first-class product kan pe thei hi kan chhuang hle. Valve leh fitting hrang hrang kan neih avangin i tui system atana solution tha ber kan pe thei ang tih i ring thei ang. Kan thil siam chungchang leh kan tanpui theih dan tur hriat duh chuan vawiin hian min rawn biak theih reng e.
