Q:What's the difference between turbine butterfly valve and manual butterfly valve?
The turbine can light and close the valve here. It is more labor-saving and reliable. It is closed and open. Manual operation is relatively difficult, but the manual action is very fast. Fast switching. General large bore turbine.
Q:Butterfly D371X5-16ZB1 what does each letter stand for?
Daily valve pressThe regular model is out of step with you. I can only explain the regularD371X5-16ZB1D is butterfly valve3 is the turbine drive7 is the clamp connection1 is the display opening signX is a rubber seal16 is 16 kg pressureI don't know the other superfluous letters
Q:Butterfly valve model D373F-16C, ask God answers
D butterfly valve, 3 turbo rotating, 7 pairs clip type, 3 eccentric F PTFE seal, 16 nominal pressure 1.6MPA, C valve body material, carbon steel
Q:What do you mean, handle, butterfly valve, hard back and soft back?
The butterfly valve of the handle butterfly valve is installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is between 0 degrees -90 degrees, when rotates to 90 degrees, the valve is fully open. This valve is mounted horizontally.Butterfly valve has an elastic seal and metal seal two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.The hard back is the metal seal, and the soft back is the elastic seal.
Q:Butterfly valve is the control valve?
The flow characteristics of butterfly valves can be approximately equal percentage characteristics, with the positioner can do adjust, is mainly used in large caliber, straight stroke control valve more than 200 volume weight will be great, it suggests using the butterfly valve.
Q:What is the national standard for clip butterfly valves?
GB/T 12238-2008 "flange and clip connection elastic seal butterfly valve"GB/T 26144-2010 flanged and clip on steel lined fluoroplastic butterfly valvesJB/T 8527-1997 "metal sealed butterfly valve"
Q:Should I connect the butterfly valve before and after the pump? Or gate valve?
The best pump outlet valve, because the valve opening control accuracy, no movement. Valve structure is strong, adjusting performance better than butterfly valve. The pump outlet needs constant switching and adjustment, so the pump outlet valve is suitable for gate valve.Life water system valve, it is best to choose the gate valve, strong and reliable, cut off the system to grasp. But the cost is higher, occupying more space.Choose 1 or 1.6, there is no principle requirements, because the water supply pressure of life is generally between 0.25-0.5MPA, can meet the requirements. Only 1.6 is more durable and stronger, but the price is higher.
Q:What does butterfly valve do?
[1] butterfly valve is also known as turn over plate valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control.[2] butterfly valve: butterfly valve refers to the closure of parts (valve or butterfly plate) for 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:Does the pneumatic butterfly valve need electricity?
Pneumatic valves do not require power, but compressed air makes electricity!
Q:Where are the exhaust valves, mud valves and butterfly valves?
The exhaust valve is used for the heating of the independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system.Mud valve, also known as cover valve, commonly used in urban water plants, sewage treatment plants sedimentation tank bottom discharge sludge.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.
