Q:What does gate valve Z41H-40 mean?
Z - that means gate valve (the initial letter of Zha)4---- is the connection form, which means flange connection1---- form of structure, which means Plain Bar wedge type rigid single gate valveH---- sealing surface overlaying ferrous carbide (initial letter of alloy steel He)40---- nominal pressure is 40 kg, or 4.0MPa, that is, PN10 at 250 degrees Celsius, the maximum working pressure is 40 kgThe material is cast carbon steel
Q:What do you mean by "2" and "200 CF8M"?
CF8M is stainless steel, and 2 is caliber 50200 and should also be bore
Q:What is plug welding gate valve?
Socket welding valve refers to the use of socket welded connection valve.Simple socket welding is to insert the pipe into the gate joint to weld.The form of socket welding is mainly used for welding small bore valves and pipes, fittings and pipes. Small caliber pipeline wall thickness is thin, and error prone edge ablation, butt welding is difficult, more suitable for socket welding. In addition, the socket of socket welding has reinforcement effect, so it is also used under high pressure. But socketweld also has disadvantages, one is the stress condition is not good after welding, easy welding penetration, pipe inside a gap, so should not be used for piping system of crevice corrosion sensitive medium pipeline system and clean high requirements for socket welding. In addition, ultra high pressure pipeline, even small caliber pipe wall thickness is also very big, can use butt welding connection, as far as possible to avoid socket welding.
Q:What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve
Yes. Globe valves and gate valves are indeed common in certain piping and operating conditions.
Q:What does the gate valve SZ45X-1.0 stand for?
Z- stands for gate valves, 4 for flange connections, 5 for wedge wedge single gate, X for rubber seals, and 1.0- for PN1.0MP
Q:Is the axial force and torque of the wedge gate valve the same?
B higher temperature. C nice wedge single gate valve is suitable for high temperature medium easy to coking. Flexible gate valve features: high temperature, a wedge type single gate valve in a special form. Comparison with wedge gate valve.
Q:Z41T one 10 gate valve and Z44T one, 10 gate valve difference
Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa
Q:Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?
2, soft sealing gate valve at the bottom of the pit. No accumulation of slag material, valve opening and closing of the failure rate is low;
Q:What does gate valve DN200PN160 mean?
DN200 refers to the nominal diameter of the valve, the unit is mm, PN160 refers to the valve tolerance pressure, the unit is 1/10MPa.
Q:Z45T-10 what kind of material is the gate valve?
Z45T-10 refers to the nominal pressure of 1Mpa gray iron valve. The meaning of letters and numbers is:(Z) - gate valve;(4) indication - internal thread connection;(5) indicating dark wedge rigid single gate;(T) - the body is made of copper or copper alloy;(10) indication nominal pressure 1 mpa.Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The gate has two sealing surfaces, and the two sealing surfaces of the most commonly used gate valves form wedge and wedge angle valves.
