Among the above-mentioned technical scheme, preferred torsional spring is two, and the one end of two torsional springs links together, has more the uniformity, and the effect of torsional spring is: when no gas or liquid flows through the flow passage, the torsion spring enables the baffle to be located at the initial position, namely the position for blocking the flow passage, due to the torsion force of the torsion spring, the gas or the liquid can drive the baffle to rotate after overcoming the torsion force, and a calibration debugging is carried out at the position, so that the precision of pointer indication is improved.

As a further arrangement of the present invention, the pointer is fixed in the rotation shaft by a bolt.

Among the above-mentioned technical scheme, easy to assemble and dismantlement.

As a further setting of the utility model, the visual sheet is distributed with scales.

Among the above-mentioned technical scheme, this scale is the scale that distributes along the direction of rotation of baffle, and the setting of scale can let the audio-visual size of seeing the flow of user.

As a further arrangement of the utility model, the visual window is composed of the annular wall which is convex outwards and is provided with the shell, and the visual piece and the baffle plate are respectively fixed at the two ends of the annular wall.

Among the above-mentioned technical scheme, the setting of annular wall can make the circulation passageway regularization, avoids changing the structure of circulation passageway.

As a further setting of the utility model, the baffle sets up with the casing is integrative.

Among the above-mentioned technical scheme, integrative setting need not set up seal structure, has avoided gas or liquid seepage to the pointer intracavity, and processing is convenient, makes the pointer clearly visible.

The present invention will be further described with reference to the accompanying drawings.
