Abstract
The hydraulic metering method requires cylinder, metering tube with marker and elastic balance unit, and features that a weight acts on piston of cylinder to cause liquid flow through transparent metering tube to elastic balance unit until the weight is balanced by reaction force generated by said elastic balance unit, and the marker in tube indicates the value of weight.
Description
The invention belongs to a kind of metering method technical field, relate in particular to a kind of method of utilizing hydraulic principle to realize computation weigh.
At present, metering method is varied, and their branches have utilized lever principle, spring principle of work and microelectric technique or the like in addition.Yet, utilize the weighing apparatus of said method manufacturing that the strengths and weaknesses of oneself is respectively arranged, general says: perhaps degree of accuracy is not high, or range of weighing is too small, or costs an arm and a leg, carries inconvenience etc.Known to just application is gone into, also do not utilize hydraulic method to make measurement instrument, and the utilization hydraulic method measure and can solve the problem that above-mentioned weighing utensil exists effectively.
The object of the present invention is to provide a kind of metering accurate, measures range is wide, low-cost metering method.
The object of the present invention is achieved like this: a kind of Hydraulic scale restatement metering method, its method realizes by cylinder body, gauge line and Spring balanced device, connect and sealing fully with gauge line between cylinder body and the Spring balanced device, full of liquid in it, be characterized in, when the piston of action of gravity on cylinder body, when the piston pressurized moves down, in the cylinder body liquid through gauge line to Spring balanced device force feed; At this moment, the gage mark under pressure in the gauge line moves with liquid flow, and the Spring balanced device also produces a reacting force simultaneously, thereby reach equilibrium of forces, liquid stops going up mobile, this moment, gage mark in the gauge line also stops to move, and points to a certain numerical value.
In the process that said method is realized, the caliber size ratio of cylinder body, diaphanometer buret and Spring balanced device can be done different adjustment, just can reach the amplification of gravity metering signal and dwindle, so can enlarge the degree of accuracy of measures range and metering.
Liquid Weighing method recited above, also can further be improved to: cylinder body and Spring balanced device can be combined as a whole, when the piston of action of gravity on cylinder body, when piston moved down, liquid flowed to gauge line under pressure, produced the opposite elastic force of a direction with the spring in the amount cylinder body, piston move down certain square from after, elastic force and gravitational equilibrium, piston stop to move, and liquid also stops to go up mobile; This moment, can demonstrate the numerical value of gravity size from the liquid level of gauge line.
Fig. 1 is one of fundamental diagram of the present invention.
Fig. 2 is two of a fundamental diagram of the present invention.
The advantage of hydraulic metering method provided by the present invention is:
1, can be accurately and accurately control liquid according to changing cylinder body and gauge line caliber size ratio Therefore variation speed and the scope of body in gauge line measure with the method, the weighing knot Fruit is accurate, scope is wide.
2, from the method, the weigher lamps structure that uses the method to make is simple, uses Convenient, and low price, long service life.
Claims (2)
1, a kind of hydraulic metering method, its method is passed through cylinder body, diaphanometer buret and Spring balanced device are realized, connect and sealing fully with diaphanometer buret between cylinder body and the Spring balanced device, full of liquid in it, it is characterized in that: when the piston of action of gravity on cylinder body, when the piston pressurized moves down, in the cylinder body liquid through diaphanometer buret to Spring balanced device force feed: at this moment, gage mark under pressure in the diaphanometer buret moves with liquid flow, and the Spring balanced device also produces a reacting force simultaneously, thereby reaches equilibrium of forces, liquid stops to flow, this moment, the gage mark in the diaphanometer buret also stops to move, and points to a certain numerical value.
2, as claim 1 described hydraulic metering method, it is characterized in that cylinder body and Spring balanced device can be combined as a whole, when the piston of action of gravity on cylinder body, when piston moved down, liquid flowed to the transparent meter pipe under pressure, produced the opposite elastic force of a direction with the spring in the amount cylinder body, piston move down certain square from after, elastic force and gravitational equilibrium, piston stop to move, and liquid also stops to flow; This moment, can demonstrate the numerical value of gravity size from the liquid level of diaphanometer buret.
