Flow is set to reach desired value by the adjusting means, while measuring the corresponding flow resistance of the adjusting means；
B. manufacture and design one section of water pipe, make the resistance measured in resistance of the water pipe under design objective flow and step A
Value is equal, and the water pipe is substituted into the adjusting means.
The embodiment of second aspect present invention additionally provides a kind of engine-cooling system bypass flow adjusting means, described
Engine-cooling system bypass flow adjusting means, including water pipe, valve seat, valve rod and valve block, are threaded on the water pipe
Interface and two pressure taps, two pressure taps are located at hickey both sides respectively, and are connected with pressure sensor, the valve
Seat is threadably mounted in hickey, and the valve rod is rigidly connected and on the valve seat with valve block, described
Valve stem tip is furnished with nut.
Further, it is provided with sealing ring between the valve rod and valve seat.
Further, the valve block is circle, and annulus, and diameter are formed less than in water pipe with the water pipe internal diameter
Footpath, the center of circle overlaps with the centre of conduit.
Further, the diameter of thread size of the hickey is more than valve block diameter dimension.
Relative to prior art, engine-cooling system bypass flow adjusting method of the present invention and device have with
Lower advantage：
The embodiment of the present invention need not carry out substantial amounts of calculating and experiment work, only by adjusting the aperture of valve block, you can
The flow resistance of branch road where easily changing, so as to accurately realize the purpose of regulation bypass flow, then measures institute by pressure tap
