Abstract

An automatic power-consumption-free constant liquid flow meter relates to a device for automatically controlling liquid flow and keeping constant. The automatic power-consumption-free constant liquid flow meter utilizes a floating rigid siphon pipe, a liquid inlet of the siphon pipe is fixed with a T-shaped floater so as to lead the siphon pipe to be integrally supported by buoyancy force, three ends of the T-shaped floater can adjust heavy objects to lead the siphon pipe to keep balanced, the integral siphon pipe synchronously changes along with change of liquid level, and then a liquid outlet of the siphon pipe and the liquid level keep a constant height difference without consuming any energy. The automatic power-consumption-free constant liquid flow meter does not affected by changes of the liquid level, and then liquid flow in the siphon can automatically keep accurate and identical.

Description

Non-power consumption automated fluid constant flow rate instrument

Affiliated technical field

The automatic controlling liquid flow velocity that the utility model relates to a kind of non-power consumption keeps constant mechanical hook-up, and its flow velocity size can be regulated.

Background technology

It is to take complicated electrical control to come the regulator solution rate of flow of fluid that at present known controlling liquid flow velocity keeps constant device, make it basic and keep constant, error within the acceptable range, this device needs consumes energy, complex structure, the cost height, degree of accuracy is not high.

Summary of the invention

Keep constant apparatus structure complexity in order to overcome existing automatic controlling liquid flow velocity, the cost height needs power consumption and the not high deficiency of degree of accuracy, the utility model provides a kind of automaton simple in structure, need not consume energy, the degree of accuracy height, and the flow velocity size can be regulated.

The technical scheme that its technical matters of solution that the utility model is taked is taked: this device is by by the rigidity U trap, support, steel wire, container, regulate weight, current meter, hydrogenerator, valve is formed, and U trap inner and outer pipes distance furthers as far as possible, is beneficial to keep balance.Siphonal liquid feeding end and T shape float are fixed, U trap is held up by buoyancy fully, and keep balance by regulating.

According to siphonal principle, the difference in height of liquid level and U trap liquid outlet is consistent then, and the flowing liquid flowing velocity just can not change in the U trap, and the fluid flow in the unit interval can be consistent equally.Be arranged on the automatic synchronous change along with the change of liquid level of U trap liquid outlet on the float, and U trap is a rigidity, so that the difference in height of liquid level and U trap liquid outlet remains is constant, no matter how liquid level changes.Like this, under the constant situation of other conditions, the flow rate of liquid in the U trap just can synchronous change, but keeps constant.Do not need to expend any external energy, realize completely control automatically.

In order to keep siphonal balance, float adopts T shape structure, on T shape fixed support is arranged, U trap is fixed on its infall middle part, three ends are provided with transversely movable weight respectively, the effect of weight is to keep siphonal balance by lateral adjustments.

U trap is positioned at the outer part of liquid container and limits with the annulus that is slightly larger than the suction pipe diameter, annulus is fixed on the container, annulus is inboard to be provided with pulley by inlet one end, annulus can move up and down U trap, but can not laterally move, annulus is equipped with pulley by in one side of pond, to reduce friction, is beneficial to U trap and moves up and down.

The U trap inboard rigidity straight bracket that be arranged in parallel, U trap is fixed, the bottom is connected the T shape support cross part on the T shape float, the top by under stretch out a horizontal stand, stationary siphon top, and proper extension, draw four metal line in cantilever tip, the cantilever tip that connects T shape float support three ends and stationary siphon top respectively, and draw a metal line and connect the U trap liquid outlet in the frame top always at this, play the effect that strengthens U trap resistance to overturning and intensity.

The U trap top is provided with level meter, and effect is to be convenient to accurately regulate U trap to keep balance.

For liquid flowing resistance is minimized, the U trap cross section is for circular. and it is capable that its round part is divided into arc, and be provided with liquid feeding mouth and valve, inlet and liquid outlet also respectively are provided with a valve, can be used for irritating and draw liquid, make liquid flow. the valve of inlet and liquid outlet also can be used for regulating controlling liquid flow velocity size.

In addition, all there is interface siphonal liquid outlet place and circular arc corner, to regulate the difference in height of liquid level and liquid outlet, realize the control to flow rate of liquid.

Locate to be provided with current meter on the siphonal float, be used for accurate regulator solution rate of flow of fluid.

At T shape float middle part, just U trap inlet filled with water turbine generator utilizes at the uniform velocity current generating in the U trap, output voltage and Automatic Frequency is consistent and need not complicated electrical adjustment devices.

The container opposite side is provided with the equipment of automatic control liquid level, and a bore by float liquid level sensor perception liquid level change, just increases feed liquor when liquid level is lower than certain numerical value greater than siphonal feed tube, is higher than certain numerical value and then reduces feed liquor.

When flow stream velocity was excessive, liquid outlet can connect a L shaped liquid outlet, kept the plane with U trap, made liquid stream resemble horizontal direction and sprayed and do not run into barrier.Its effect is to prevent that high velocity liquid stream from influencing the unanimity of liquid level difference to the reacting force of object generation.

The beneficial effects of the utility model are: the controlling liquid flow velocity keeps constant automatically, need not consume energy, and flow velocity can be regulated, the degree of accuracy height, and simple in structure, cost is low, the reliability height.

Using method: earlier with U trap two ends valve closing, fill liquid, close the top valve again by the inlet at top, open U trap inlet valve, open the liquid outlet valve then, adjust flow velocity, and U trap keeps horizontality when regulating float three end weights.Just can make that the flow velocity of liquid is consistent in the U trap this moment, is not subjected to the influence that liquid level changes in the pond.Automatically the control level gauge starts simultaneously.When liquid level was reduced to the lower sensor position in the pond, Xiang Chizhong poured into liquid, and its flow velocity is greater than the flow velocity of liquid in the U trap.When liquid level rises to the upper sensor position, stop Xiang Chizhong and pour into liquid.
