What are the differences between the clamping and flange styles of valves?
The clamp type is light and self sealing, and the installation is very simple, and the installation and adjustment are easy. More and more pairs of clip valves are used in the middle and low pressure pipelines.
Would also like to ask the 2 floor, in general, even if the length of the structure of a very short clip on the butterfly valve, the closure of the pipe along the direction of the thickness of the flange will be more than spacing it?
This problem, mainly refers to the butterfly valve in two forms, pairs of clamp and flange type:The clip butterfly valve (valve itself without flange) is a double headed bolt to connect the valve between the two pipe flanges. The clip butterfly valve is simple, small and light in weight and 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. The following is a manual clip on butterfly valve. The following is an electric butterfly valve:Turn left and turn right |Turn left and turn right |Flanged butterfly valves are flanged on the valve and bolted to both ends of the valve to connect the flanges to the pipe flanges. Sealing surface wear resistance, long service life. The utility model has the advantages of unique structure, flexible operation, labor saving, convenience, and high and low pressure without the pressure of the medium. Here is the manual flange butterfly valve, the following is the electric flange butterfly valve:Turn left and turn right |Turn left and turn right |On the clip and flange flange specifications are the same, just on the flange bolt valve with long length of 2 times the thickness of the valve flange nuts + +2 thick thick, without flange clampvalves itself; as long as the open bolt nut, then the pipe at both ends of the valve are not normal work.Bolt flange type with relatively short length of 2 times the thickness of +2 flange nuts, flange thickness "valve body flange and pipe paired by bolts, locking nut; when the flange bolt and nut end is removed, does not affect the normal operation of the other end of the pipe.
