Description
Technical field
The utility model relates to a kind of liquid-level auto-control device.
Background technique
For the container of band press operation, such as gas-liquid separator or gas-liquid two-phase absorption tower, constant liquid level is very important to device stable operation.Liquid level high to raw material or gas phase ingress time, liquid phase enters up-stream system, affects charging or air inlet; When liquid level is low to moderate liquid-phase outlet place, compressed gas enters downstream liquid phase systems, affects liquid phase reclaimer operation.
Existing gas-liquid separator Liquid level often adopts outlet Liquid level adjusting valve to control, Liquid level adjusting valve is by SC sigmal control aperture, control logic is complicated, and in running Liquid level adjusting valve easily there is bite, power-off, the inefficacy operating mode such as to die, cause Liquid level to be lacked of proper care; Meanwhile, because control system is arranged on control room usually, signal transmission distance is long, has decay in transmitting procedure, and therefore program control regulative mode is not suitable for the Liquid level of mounting point away from the container of rack room.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of for the present situation of prior art not need artificial or program intervention can the liquid-level auto-control device of automatically maintaining liquid level.
The utility model solves the problems of the technologies described above adopted technological scheme: this liquid-level auto-control device, it is characterized in that comprising:
Base is tubular structure, is sealedly connected on the liquid-phase outlet of container bottom;
Valve plate, buckle closure, on the port of base, is hinged on base; Valve plate is provided with through hole;
Cover plate, buckle closure is on through hole, and cover plate one end is hinged on the upper surface of valve plate, and the other end is buckled on the upper surface of valve plate;
Ball float, is connected with described cover plate by link.
Preferably, the direction of rotation of described valve plate and described cover plate.The change of this structure to liquid level is sensitiveer, and Liquid level is more accurate.
Described base can also be provided with the limiting stopper for limiting described valve plate rotation angle.
The conveniently connection of link and the interlock between valve plate and cover plate, can be provided with handle on described cover plate, described link is connected on handle.
In above-mentioned each scheme, link can select as required of the prior art any one, such as bar, preferably, described link is flexible chain.
Compared with prior art, liquid-level auto-control device provided by the utility model adopts Mechanical course to substitute complicated program control, thoroughly solve existing Liquid level adjusting valve and occur the problem that bite, power-off, the inefficacy operating mode such as to die cause Liquid level to be lacked of proper care, solve the problem that existing Liquid level adjusting valve mounting point is limited, and sensitive to the variation sensing of liquid level, control accurately.
Liquid-level auto-control device provided by the utility model is especially suitable for gas-liquid separator and gas-liquid two-phase absorption tower, and the fluid level control valve as gas-liquid separator and gas-liquid two-phase absorption tower uses.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment using state schematic diagram;
Fig. 2 is the plan view (eliminating ball float and link) of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
As depicted in figs. 1 and 2, this liquid-level auto-control device comprises:
Base 1, being arranged in container 10, is tubular structure, the liquid-phase outlet 9 bottom the container 10 that is tightly connected.
Valve plate 2, buckle closure is on the port of base 1, its one end is connected on the sidewall of base 1 by the first hinge 5, and remaining part can open or close base port along hinged upset under external force.The sidewall of base 1 is also provided with limiting stopper 8, for limiting the rotation angle of valve plate 2.The maximum opening of the present embodiment valve plate 2 is less than 90 °.Valve plate 2 is also provided with the through hole 21 being communicated with base intracavity and container intracavity.
Cover plate 3, buckle closure is on through hole 21, and its one end is connected to the upper surface of valve plate 2 by the second hinge 6, and the other end is buckled on the upper surface of valve plate 2.Cover plate 3 is provided with handle 31.
Ball float 4, forms moment for generation of buoyancy constraint to valve plate 2 and cover plate 3, thus pulls the port of cover plate 3 and valve plate 2 rotating opening base 1; Ball float 4 is connected on handle 31 by link 7.Link 7 can be the shaft of rigidity, and the present embodiment is flexible chain thing.
The working principle of this liquid-level auto-control device is described below:
Before operation starts, container bottom is without liquid level, and ball float does not have buoyancy, and under the effect of respective gravity, valve plate and cover plate are all closed; When the liquid level in container rises gradually, until liquid level produces buoyancy to ball float, by link, pulling force is formed to cover plate, this pulling force raises with liquid level and increases, until during the moment of pulling force to cover plate is greater than container inner pressure, liquid phase pressure, cover plate gravity three are formed cover plate moment sum, cover plate is opened; Liquid phase in container enters container liquid-phase outlet from base and flows out, until the pressure balance of valve plate upper and lower; When the pulling force that ball float buoyancy is formed is greater than the difference of valve plate gravity torque and valve plate buoyancy torque to the moment that valve plate is formed, ball float pulls open valve plate by cover plate, and liquid flows out along pressure reduction.After this, if liquid level raises, then pulling force increases, and valve plate opening angle increases, and liquid phase stream outflow increases, and when liquid level reaches upper control limits, under the effect of positioning block, the aperture of valve plate no longer increases; If liquid level reduces, valve plate opening angle reduces, liquid phase stream outflow reduces, when the moment being decreased to constraint generation is less than the difference of valve plate gravity torque and buoyancy torque, valve plate is closed, and liquid level continues to reduce, when drag torque is less than the difference of cover plate gravity torque and buoyancy torque, cover plate is closed, and the liquid phase passage that leaks is closed completely.Therefore, do not need manual operation, liquid level can be kept to float in certain area.
