A kind of crest discharge measuring instrument comprises cylinder-like shell, base, cylindric loam cake, axis, concentric stroking moving plate and indicateing arm, and cylinder-like shell is provided with an outer groove and an inner groovy, and indicateing arm is positioned on the inner groovy; Cylinder-like shell is fixedlyed connected with base, and an end of axis is fixed on the central point of base, and the other end is provided with screw thread; The concentric stroking moving plate is sleeved on the axis, the diameter of concentric stroking moving plate be adapted to cylinder-like shell internal diameter and can be up and down in cylinder-like shell, a spring is fixed in the centre of concentric stroking moving plate, and the other end of this spring is sleeved on the axis that is provided with screw thread one end; Cylindric loam cake spiral-lock is provided with one deck dividing plate in the cylindric loam cake on the upper port of cylinder-like shell, the position, the center of circle of dividing plate is provided with a little cylinder, is provided with a nut in the little cylinder, and expose outside the little cylinder on this nut top; After the installation, the screw thread of axis upper end firmly is connected by screw thread with nut; Cover on cylindric and be provided with an expiration Zi, one of the lunar mansions, the bore on this expiration Zi, one of the lunar mansions top is less than the bore of bottom, and the external diameter of bottom is less than the internal diameter of cylindric loam cake.
Spring on the concentric stroking moving plate is a cylindric helical spring.
Base is provided with venthole, and this venthole is evenly distributed on the circumference of base.
Outer groove and inner groovy all are the strip grooves, and the degree of depth of outer groove is less than the thickness of cylinder-like shell wall, and inner groovy is positioned at outer groove and is communicated with the inner chamber of cylinder-like shell.
The cylinder-like shell of outer groove one side is provided with numerical scale.
Dividing plate is provided with air inlet, and this air inlet is evenly distributed on the circumference of dividing plate.
Dividing plate is provided with one deck buffer film towards the one side of shell upper port, and buffer film is sleeved on the little cylinder.
Behind the measuring instrument installation forming, because the spring on the concentric stroking moving plate is fixed on concentric stroking moving plate and the axis, under the spring tension effect, the concentric stroking moving plate is positioned on the upper port of cylinder-like shell.When exhaling facing to the expiration Zi, one of the lunar mansions, the air-flow of exhalation blows the concentric stroking moving plate and moves to the other end of shell along the inwall of cylinder-like shell, and the concentric stroking moving plate drives indicateing arm and moves along the other end of inner groovy to shell simultaneously.When indicateing arm reached the final position, the scale value on the indicated shell of indicateing arm was exactly the crest discharge value of exhaling.
The utlity model has reasonable in design, easy to manufacture, be easy to carry, characteristics easy to use.
