Brake said pneumatic valve model establishment method

pneumatic valves open and close a gate, is a brake disc movement direction perpendicular to the direction of flow and the brake pneumatic valve can only be fully open and close, not door parameters vary. Brake pneumatic valve is sealed with mandatory, the pneumatic valve is closed, to rely on outside force forced the ram pressure to the pneumatic seat, to ensure the sealing surface sealing.

brake pneumatic valve type:
brake pneumatic valve type of manual brake mainly for the pneumatic valve symbol, additional requirements, driver, connection, structure, seal, pressure, material combination segment.


brake pneumatic valve model establishment method:
additional code: brake solenoid pneumatic valve, corrugated pipe gate DZ WZ said low temperature brake pneumatic valve, pneumatic valve, vacuum brake NKZ PZ pneumatic type knife gate valve.
pneumatic valve type brake said: Z;
drive way said: no code manually, electric hydraulic turbine worm, - Bevel gear drive, pneumatic, - Electric;
connection said: flange connection, welding, the wafer;
structure said: flexible disc, stem wedge type single ram, - Rising stem wedge type double ram, - Parallel type single ram, rising stem - Rising stem parallel-type double ram, non-rising stem wedge type single ram, non-rising stem wedge type double ram, non-rising stem parallel single ram, non-rising stem parallel double ram;
sealing material material: W pneumatic valve directly processing, T alloy, X, F fluorine plastic, rubber, H - Cr stainless steel, hard alloy, M Y monel alloy;
class said: PN. - Mpa，=. MPA said pressure is 10 kg, LB - LB class said American standard pressure, - K said, stress level;
pneumatic valve body material said: Z - T alloy nodular cast iron, grey cast iron, Q, C carbon steel, stainless steel, P R stainless steel, V molybdenum chrome vanadium steel.

brake model, an example is given to explain the pneumatic valve:
, ZX - / Q said: Z pneumatic valve, flange connection, rising stem gate wedge rubber seal, the single ram, X/kg pressure;
、ZX - Q said: Z pneumatic valves, electric gate,, flange, non-rising stem wedge type single ram rubber seal, kg pressure, X.

common brake pneumatic valve pneumatic valve types are:
pneumatic seal gate valves of the elastic base seat: ZX, useful; Pneumatic valve:
stainless steel gate ZW, ZW, useful, useful;
electric brake pneumatic valve: useful, useful, ZW, useful, ZX, useful;
pneumatic brake valve, ZF, useful, ZW;
pneumatic valve welding gate: useful, useful, useful, NKZH; ZH、ZH、ZH、ZH;
serous pneumatic valve: ZX, useful, ZX, useful, ZX, useful;
pneumatic type knife gate valve: PZH, PZH, PZH, PZH, PZH, PZH, PZH, PZH; Pneumatic valve:
stem gate ZX, useful, ZX, useful, ZX; Pneumatic valve:
non-rising stem gate ZX, useful, and government;
spiral gate: LMD one-way, LMS bidirectional;
bevel gear brake pneumatic valve: useful, useful, useful, useful, useful;
pneumatic valve, corrugated pipe gate WZH, WZW; Pneumatic valve:
low temperature gate DZH, DZW, DZY, DZF, DZH, DZW, DZY.
