Q:Butterfly valve D71X-16 and D71X-16Q what is the difference?
The two difference is that the body of the material is not the same, 16 behind with no sign, expressed as a default, is carbon steel (usually C), if you need to specify material, just behind with symbols, such as Q nodular cast iron, stainless steel P.Butterfly valve refers to the closure of parts (valve or butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow. Butterfly valve categories are: handle butterfly valve, turbine butterfly valve, pneumatic butterfly valve, electric butterfly valve and so on.
Q:Electric butterfly valve (not take the lead) what do you mean?
Electric butterfly valve, as its name implies, consists of an electric actuator and butterfly valve, and the customer does not take the lead, that is, without the electric actuator, only the butterfly valve can be provided.
Q:What is the D37-10Q butterfly valve?
The model is too simple, right D37A1X-10QB1, D: valve, 3: turbine head, 7: on the vertical plate clamp, A1: type A, X: type of rubber seat, 10: nominal pressure valve Q: is ductile iron, B1: plate is made of ductile cast iron
Q:What's the meaning of butterfly valve d371po?
According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve3== transmission: worm gear7== connection mode: clip type1== structure: midlinePo== sealing surface material: lining PoPo== propylene oxide (PO)
Q:What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
The clamp and flange are the two connections.The clip type is cheaper and the price is approximately 2/3 of the flange.The length of the clip type valve bolt is longer, and the requirement of construction accuracy is higher. If the flange on both sides is wrong, the bolt will be subjected to greater shearing force, and the valve will leak easily.
Q:What's the difference between cut-off valve, gate valve and butterfly valve? What's the difference in the working principle?
Stop valve, leak small, gate valve, leak big, butterfly valve switch fast
Q:Butterfly valve is generally used in what position?
Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, environmental protection, chemical smelting and power building water supply and drainage engineering system in conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.
Q:Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?
This butterfly valve in our factory called butterfly, 4 represents the connection of the flange connection flange is French, 41 in 1 on behalf of butterfly valve, W represents the body seal, is C that is actually the correct type of cast steel, should be D41W-1C. Suitable for ventilation, smoke, and these media.
Q:how does variable valve work?
The variable is the valve timing. The spark plug fires a split second before the piston reaches the top of the stroke, to give the fuel a bit of time to burn. But, the faster the piston travels in the bore, that split second gets shorter shorter. So the engine computer changes when the spark plug fires when the valves close, to maximize the power from each ignition stroke.
Q:What's the difference between electric butterfly valve and electric two way valve?
The electric two way valve is specially used for the fan coil of the central air conditioner. It is usually used in conjunction with the temperature controller. It can realize the automatic regulation of temperature. But the electric butterfly valve and the electric control valve belong to a kind of variety, and they are important execution units in the field of industrial automation control.
