Q:What does the triplex of pneumatic butterfly valve mean?
Upstairs is quite right, but now seems to use very little oil mist, and now generally referred to as "triple parts" as if: filter pressure reducing valve, solenoid valve, with the valve position feedback switch.
Q:butterfly valves d7a1x5
D- valve type (butterfly valve), 7- connection mode (to clamp), A- valve shape mode (A), 1- structure form (vertical plate), X5- valve seat sealant species (Ding Qing, NBR)
Q:What does "10" in the butterfly valve "D71X-10" mean?
The pressure of 10 kg 1.0MPA is usually cast iron
Q:The difference between the electric control valve and the electric butterfly valve, respectively, the application situation
Electric butterfly valve is a kind of electric control valve.There are many types of valve body, usually through the single seat, straight through two seat, angle, diaphragm, small flow, three pass, eccentric rotation, butterfly, sleeve type, spherical and so on 10. In the selection of control valve valve prior to the media, process conditions and parameters to control the process of careful analysis, to collect sufficient data to understand the system requirements on the control valve, according to the data collected to determine the type of valve to be used.
Q:How does the pneumatic butterfly valve control the angle of opening?
This is really not good, control seems to be pneumatic defects, can only rely on the feeling
Q:What do you mean, handle, butterfly valve, hard back and soft back?
My understanding is: PTFE butterfly valve is a hard back; soft rubber seat is a soft back
Q:Butterfly valve in use when should pay attention to what problems?
In the process of using the butterfly valve, you should timely notice valve state, without excessive loosening, no abnormal leakage, or abnormal high temperature and so on, if there is abnormal, should immediately close the valve, to identify the reasons for the problem, treatment after use, it is also very important.
Q:Why use special flanges for butterfly valves?
Because to use special flange butterfly valve butterfly flange diameter is just the butterfly inside diameter of DN coincides with a slot in the back, and this is the connection of the steel pipe is inserted into the slot, so as to ensure the sealing effect, but with a flange piece of ordinary cannot guarantee the effective sealing effect.Butterfly valve plate installed in the direction of the diameter of the pipe. Butterfly valve structure is simple, small size, light weight. Consists of only a few components. The utility model can be rapidly opened and closed only by rotating 90 DEG, the operation is simple, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium passes through the valve body, so the pressure drop produced by the valve is very small, so the flow control characteristic is better.If the butterfly valve is used as a flow control, the main thing is to correctly select the size and type of valve. Butterfly valve structure and principle, especially suitable for making large-diameter valves. There are two kinds of butterfly valves commonly used: clip type butterfly valve and flanged butterfly valve. The clip type butterfly valve is a double headed bolt connecting the valve between the two pipe flanges. The flange type butterfly valve is provided with a flange on the valve, and a bolt is used to connect the flanges at the ends of the valve to the pipe flange.
Q:What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
For clip butterfly valves, there are no flanges at the ends of the butterfly valve. There are only a few guide bolts. The valve is connected with the end flange with a set of bolts / nuts.In contrast, the demolition to facilitate some of the lower cost of the valve, but the drawback is that a sealing surface problems, the two sealing surfaces have to be taken apart.Flange butterfly valve at both ends of the flange, and pipe flange connection. The seal is relatively more reliable, but the valve is of relatively high cost.
Q:The difference between the directly buried gate and the flange valve and butterfly valve
The flange gate valve is stable and reliable when used in the pipeline, so the flange gate valve is used on the high pressure pipeline.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.
