Abstract

The utility model discloses a simple industrial liquid dosage control device, which comprises a water inlet pipe, a plug and an anti-drifting net. Water gets in from a water feed pipe so enable water level of a water pool to rise, under the action of buoyancy, the plug can gradually plug the water inlet pipe along with the rise of the water level and then completely plug a water inlet, water in the water pool becomes less during the use because of leakage or evaporation and other reasons, the water level drops, the plug falls off under the action of gravity, the water inlet is opened and water can get in again, therefore, circulation is achieved. The method can accurately and automatically control the water level within a certain range, the operation is simple, and the cost is low.

Description

Industrial type fluid adds amount control device

Technical field

The present invention relates to a kind of industrial type fluid and add amount control device, especially the liquid of being made up of water inlet, chock plug and the anti-net that drifts about adds amount control device.

Background technique

The equipment that has in industrial production need be used water cooling, certain produces heat when partially absorbing equipment work the cold water access arrangement, flow to the circulating water pool cooling then, the cooled water of pump handle is released and is pressed to water inlet and enter the circulatory system, cooling equipment once more, water so circulates the reduction device temperature, assurance equipment proper functioning, circulating water has evaporation or pipe reason such as leak at circulation time, cause quantity of circulating water to reduce, if the circulating water pool water level is low excessively, the circulating water that water pump is extracted out is few, will cause equipment and burn, even have an accident because cooling is untimely.Has plenty of the design band ball float, putting on line is connected with control spanner line, ball float rising pulling brake valve stops to add water behind the last water: the enterprise that produces coal gas, the gas pipe line that has also needs to seal with certain water yield, if the gas pipe line internal pressure increases suddenly, pressure can release by the water-stop place, reduces pressure, guarantees the safety of coal gas and facility.The gas pipe line water seal is had plenty of at present by opening water pipe and is not stopped to add water, and seal tank has flow-off, flows out from flow-off if water level surpasses certain water level superfluous water; Or manually add water, and or electrical inductor is installed, sense water level and reduce and open priming valve and add water or the like automatically.These methods operator on duty must diligently observe circulating water pool water level or sealing water level, in time opens priming valve and adds water, and guaranteed water level is stabilized in certain limit.Increase operator on duty's workload, add water if the while operator on duty forgets, accidents happened probably; Cause waste water resource; And cost height.

The model utility content

The technical problem that the utility model solves is (being example with water), utilizes the buoyant characteristics of water, and water level rises or descends, and chock plug is fluctuated at the water surface, thereby block or open water intake, controls the addition of water, reaches the purpose of automatic dosage.

In order to address the above problem, the opening of water inlet will be higher than the highest order certain distance of liquid level, flaring water intake down, an anti-drift net is installed in the water intake bottom, in net, place one and the corresponding chock plug of water intake shape, the lower limb of chock plug has O-ring seal, chock plug density is less than the density of water, chock plug includes the plastics of certain strength and toughness as using the foam outside, the wood materials that density is very little etc., these materials are wanted to bear certain pressure, flaring water outlet connects the anti-drift string bag, the control chock plug is unlikely to drift about in container, water is understood normal loss in use, make drawdown, when drawdown, chock plug is because the action of gravity whereabouts, leave water outlet, water outlet is equivalent to open valve because of there not being obstruction, the pressure of water pipe internal water is greater than ambient pressure, water flows out in water inlet, and in the pond, liquid level progressively rises, because chock plug density is less than the density of water, therefore chock plug floats with liquid level, progressively flaring water outlet is all stopped up, thereby stops to add water; Water in the pond normally uses, and owing to seepage or evaporation reduce, makes drawdown, when drawdown, chock plug is because gravity fall is left flaring water outlet once more, the water outlet water outlet, so going round and beginning again just can guarantee that liquid level water level is stable and be controlled at a certain scope.

Description of drawings

Below in conjunction with the drawings and specific embodiments it is described in further detail:

Phase diagram when Fig. 1 is the water outlet water outlet;

Fig. 2 is anti-drift net schematic representation;

Fig. 3 is the chock plug schematic representation;

Fig. 4 is the scale schematic representation of fixedly water outlet;

Embodiment

Shown in Fig. 1,2,3,4: water intake is opened down, and water intake 3 is made horn shape; Do also flue with the corresponding chock plug 4 of water intake, the bottom is designed to hemispherical, because the bottom is designed to hemispherical, spherical area is big, and center of gravity is on the low side, is convenient to increase buoyancy, center of gravity is convenient to flaring chock plug head up in the bottom, flaring chock plug and spherical contacting point are designed to O-ring seal 5,6, and its size is just in time being wrapped flaring water inlet, promote that chock plug better goes to be sealed into the mouth of a river; An anti-drift net 10 is installed in the water intake bottom, and the chock plug net is got up, and be unlikely to water level and reduce when too much,

Chock plug other places in container of drifting about.When the water level reduction, chock plug is because action of gravity descends, and water intake is opened (being equivalent to valve open), and water flows out in water pipe, enters the pond, pool wall 7, water 8, water line (liquid level) 9; Pond (groove) water level constantly raises, because floating function makes chock plug float with water level, stops up water intake gradually, and water level reaches specified altitude, and floating function makes chock plug block water intake, is equivalent to throttle down.The work that so goes round and begins again reaches the purpose of automatic control water level.

Water level a period of time need raise or a period of time needs to reduce, and also can reach automatic control, and is shown in Figure 4: Position Design one scale 1 at needs is also fixing, presses the needs of height of water level above the scale, design different heights fixing device 2, and as clamp, jack etc.; The fixation 12 that the intake pipe head design will be complementary with the scale fixture is used for fixing intake pipe.If 5 meters of the highest needs of water level in water pool, the intake pipe head moves on to 5.5 meters and is fixed on the clamp of scale, if water level in water pool needs 2 meters, the intake pipe head moves on to 2.5 meters and is fixed on the clamp of scale, 0.5 the height of rice is the height and the intake pressure that need take into account water pipe, chock plug, the water pressure energy in pond makes chock plug stop up factors such as water intake fully.Intake pipe can move up and down, and the intake pipe head is a hard material, and lower part is a flexible pipe 11, can elongate as flexibles such as bellows, leather hoses, or compression, or fold next pipe, purpose is to raise or to reduce the pipe height.

Claims (2)

1. an industrial type fluid adds amount control device, mainly containing intake pipe, chock plug and the anti-net that drifts about forms, it is characterized in that: flaring water intake down, an anti-drift net is installed in the water intake bottom, place one and the corresponding chock plug of water intake shape in net, the lower limb of chock plug has O-ring seal.
