Why use special flange for butterfly valve?

The utility model has the advantages of quick opening and closing at 90 DEG rotation, simple operation, and 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.

there is a pair of flange drawings, the above mark is 6-M12 evenly distributed 23 drill 24, what is the specific meaning?

If the bolts have been purchased, they will be drilled 27, and if the size of the workpiece is not enough, it must be changed to attack 21.However, since the M12 thread usually has a thread length of 10 to 12, the lengthened length is 15 to 16, and 16 is the thread matching surface. Plus 2mm margin, can be designated as tapping 18, drilling 22., so that processing operators more relaxed.As a result of the distribution of force per thread teeth suffered extremely uneven, some teeth burden some teeth almost no stress, length too long, is not obvious to improve the strength of thread, but on the processing and assembling to increase a lot of trouble, so, if it is not a special case, do not add the length of thread. Therefore, the ideal is to attack 12 drill 16 (put 2mm installation allowance), if the strength is not enough, to see whether the installation position can be changed to M14, according to the specific circumstances.

What's the thickness tolerance of neck flange?
