Description

Be used for the spacing air-out apparatus of liquid level

Technical field

The utility model discloses a kind of spacing air-out apparatus of liquid level that is used for, and belongs to mechanical type restriction liquid level raising device manufacturing technology field, not only can be used for trace and add liquid metering outfit, also can be used for the spacing device of other level control (LC).

Background technology

Liquid (liquid) metering system mainly is to carry certain amount of fluid, the device that is used for the liquid quality measurement can measure its flow by liquid flowmeter or the flow pump that is installed in the pipeline, can calculate according to the known density of measuring liquid during the liquid flowmeter metering, thereby learn the quality of measuring liquid, general this metering method is applicable to the metering of big quantity of fluid; In the time of when micro liquid measures, also can adopting the metering of pump formula, at first carry the fluid flow of setting value with the manual measurement pump, manually weigh then, until proofreading and correct to meeting required flow, this metering method must add manual synchronizing, and the pressure of flow pump, temperature and density of liquid can have influence on the precision of metering.

The inventor creates a trace and adds the liquid automatic metering equipment, it adopts processor to control the purpose that each execution module reaches automatic measurement liquid quality, quantitative liquid is stored in one weighs in the container, for the capacity creation one of controlling this container of weighing is used for the spacing air-out apparatus of liquid level, so proposition of the present utility model is just arranged, simultaneously, the spacing air-out apparatus of this liquid level also can be used for the control of liquid container capacity in the other field.

Summary of the invention

At the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, highly sensitive spacing air-out apparatus of liquid level that is used for.

For reaching above purpose, the utility model is achieved through the following technical solutions:

The utility model comprises outlet passageway, central shaft and buoyancy piece, and wherein outlet passageway is provided with the two-layer sheet of giving vent to anger in its passage, and the periphery and the outlet passageway of the sheet of giving vent to anger are connected as a single entity, and on the two-layer sheet of giving vent to anger venthole are arranged all; Central shaft, through the two-layer sheet of giving vent to anger, its top stretches out in the gas outlet of outlet passageway, and the central shaft bottom is connected with buoyancy piece; Described two-layer giving vent to anger has sealing ring between the sheet, sealing is located on central shaft and affixed with it, and sealing ring can move up and down with central shaft and buoyancy piece, makes the air in the gas outlet be communicated with outside air or completely cut off.

Further, described sealing ring external diameter is less than the internal diameter of outlet passageway, makes between the tube wall of sealing ring and outlet passageway gapped.

Further, there is edge of a knife ring in the venthole outside of giving vent to anger on the sheet in the upper strata of the described two-layer sheet of giving vent to anger, and its edge of a knife ring footpath is less than described seal ring cover external diameter, and the air inside and outside the sealing ring seal makes this gas outlet during with edge of a knife loop contacts completely cuts off.

Further, described sealing ring upper surface has sealing gasket, sheet better seals so that give vent to anger in itself and upper strata, laminar surface has convex under the sealing ring, lower floor gives vent to anger gappedly between sheet and the sealing ring during normality, makes lower floor's give vent to anger venthole of sheet of venthole, sealing ring external series gap and the upper strata of sheet of giving vent to anger form gas channel.

Further, described buoyancy piece is ball float or buoy.

When the utility model uses, be installed on pipeline or the container, buoyancy piece is positioned at more than the liquid level, and residing space has only this exhausr port of breather line, and during normality, the space more than the liquid level communicates with ambient atmosphere by the air flow channel of outlet pipe; Make buoyancy piece upwards when liquid level raises, central shaft and seal make progress together, when seal and on when giving vent to anger the edge of a knife loop contacts of sheet, this moment, air flow channel was blocked, the above space of liquid level forms vacuum, by being connected in the alarm equipment alarm of this device, illustrates that liquid level reaches default mxm..The utility model is a kind of mechanical type liquid level stop means, can be widely used in the qualification of the liquid level in the container in the other field, and in the water plug such as toilet, if use the utility model, 10-20% can economize on water.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment: structure as shown in the figure, the utility model comprises outlet passageway 1, central shaft 2 and buoyancy piece, wherein be provided with the two-layer sheet 4,5 of giving vent to anger in the outlet passageway 1, the periphery of the sheet of giving vent to anger and outlet passageway 1 are connected as a single entity, and on the two-layer sheet 4,5 of giving vent to anger venthole 42,51 are arranged all; Central shaft 2 is through the two-layer sheet of giving vent to anger, and its top stretches out in the gas outlet of outlet passageway, and central shaft 2 bottoms are connected with buoyancy piece; Described two-layer giving vent to anger has sealing ring 6 between the sheet, sealing ring 6 is placed in central shaft 2 and affixed with it, and sealing ring 6 can move up and down with central shaft and buoyancy piece, makes the air in the gas outlet be communicated with outside air or completely cut off.
