The rotation of piston (11) is delivered to counter (70) by shift fork (124) and gearing (72), thereby realizes counting and measurement.
The course of work:
When fluid (water) enters in the hydroecium body (10) that is assemblied in shell (4), under the effect of the energy of fluid own, it is straight line not only but also be the compound motion (waving) of rotation that the piston (11) that is restricted to hydroecium body (10) and dividing plate (104) is done, piston (11) drives group handle (122) and rotates with the shift fork (124) of dialling handle (122) formation one, meanwhile under the promotion of piston (11), the water delivering orifice (120) of fluid (water) through water box cover (12) that measured in the hydroecium body (10) is discharged from.
Be carved with 50 scales on the drive plate circumference, each lattice scale is represented 0.0002m
3Fluid (water) amount.
When the utility model is installed on the water pipe, because fluid itself has certain pressure or weight, when its process hydroecium body, piston (11) in the hydroecium body rotates and drives by gearing (72) the digital wheel rotation of counter (70), calculate the Fluid Volume of this volume of flowing through in the unit interval, it is the instrument that a kind of increment of borrowing the convection of energy body of fluid own carries out METHOD FOR CONTINUOUS DETERMINATION, and each recruitment is exactly to flow through the quantity of this volume by counter, the flow of integrating fluid.
It is generally used for not containing the volumetric measurement of the fluid, condensed fluid, high viscosity liquid etc. of solid impurity.
Whether volumeter contacts with fluid according to counter, can be divided into two kinds of wet type and dry types.Wet flow indicator is meant that counter integral body is immersed in the fluid that is measured, and fluid directly passes through counter after flowing out from the metered volume chamber, and the dry type flowmeter is then opposite, and fluid flows out the back without counter from the metered volume chamber.
Counter dial of the present utility model separates with the liquid of flowing through, and it not only guarantees transparent counter dial clear reading, also for realizing that electronics is far read technology and condition has been created in IC-card application technology aspect the foreseeable future.
The utility model is by the reliable shell that not influenced by electromagnetic induction, and shell is divided into upper and lower casing, and material is made by the aluminium alloy of high-quality, brass, engineering plastics (PP-C) etc.Inner structural members adopts nontoxic, harmless, wear-resistant, corrosion resistant highstrenghtpiston and stainless steel to make.
