Description
Technical field
The present invention relates to a kind of air remover of water-heating system, be specifically related to that a kind of to have a branch dried up with air and air is got rid of water-heating system air remover and the method for function.
Background technology
In the north, water-heating system is the warming installation of the indispensability of every household.But the prerequisite that water-heating system can safe and effective operation is not have air in the whole system.When having air in the system, can cause following harm to system: cause the chemical oxidation effect of metal parts and air in the system; The thermic load loss of heat radiation end or whole system; The heat energy conveyance loss of the water pump loss of flood peak and heat carrier.At present in water-heating system, the air existing way mainly is three kinds of static air bag, the air bubble that is mingled with and the air that are dissolved in the water.Main exhaust apparatus is divided into two kinds of high-order air bleeding valve and concentrated air-separating plants in the water-heating system, but the former need sometimes manually, underaction, the latter then can not provide enough low flow velocity to make air bubble effective isolation and the eliminating that comprises microvesicle.
Summary of the invention
The objective of the invention is to invent a kind of water-heating system air remover, provide a kind of effectively with air elimination methods in the water-heating system, the factor that influences metal parts material corrosion speed, thermic load loss, the water pump loss of flood peak and the conveyance loss of heat carrier heat energy is got rid of, thereby improve service life and the heat transfer efficiency of metal material, guarantee the quiet comfortable operation of water-heating system.
In order to achieve the above object, device of the present invention mainly comprises: water inlet pipe, free floating ball, pressure valve, baffle plate, exhaust-valve, air ejector and outlet pipe.
The water inlet pipe of emptier links to each other with water-heating system, and the water in the water-heating system enters into emptier by water inlet pipe.
In emptier inside a free floating ball is arranged, free floating ball links to each other with outlet pipe by valve.Free floating ball is the stainless steel hollow float of a fine gtinding, it is characterized in that: the external diameter of free floating ball is more smaller than the internal diameter of emptier cavity, and ball float can float by easy on and off, and can not produce frictionally damage with valve.When water entered, the buoyancy that utilizes ball float was different with gravity, makes ball float upwards float, and the water in the emptier is discharged by outlet pipe by valve.
After water enters emptier inside by water inlet pipe, because the caliber of water inlet pipe is much smaller than the internal diameter of emptier internal cavity, by fluid mechanics principle as can be known: can not interrupt when flowing in pipeline owing to fluid, can not pile up, equate namely have following continuity (conservation of mass) equation to set up so in the unit interval, flow through the water quality in the arbitrary cross section of pipeline:
ρ
1S
1V
1=ρ
2S
2V
2In=constant the formula: ρ-density; S-pipe section is long-pending; V-flow velocity
Can reach a conclusion thus: the flow velocity at the thick place of caliber is less, and that caliber is carefully located flow velocity is bigger, that is to say that air velocity and pipeline section area are inversely proportional to greatly.Therefore, when water entered in the emptier by water inlet pipe, the flow velocity of water reduced, in zone that flow velocity is lower of the inner formation of emptier.The air bubble that comprises microvesicle that is mixed in this zone in the water has the time enough rising to form bigger bubble, and finally breaks, and the air that is wrapped in wherein can discharge, because the difference of water and air, air can accumulate in the top of device.
At the top of emptier exhaust-valve and air ejector are housed, discharged by air bubble and water in the air that accumulates in the emptier top that is mingled with extracted out by air ejector by exhaust-valve.At the air ejector duration of work, the emptier pressure inside is very low.By Henry's law as can be known: at a certain temperature, the equalizing pressure of this gas is directly proportional on the concentration of certain gas in solution and the liquid level.And this law is useful too for volatile solute in the weak solution, and experiment shows that this law is only correct when having only the solubility of gas in liquid not really high.In general, airborne main component nitrogen and the solubility of oxygen in water are very little, and formed solution belongs to the weak solution scope.Therefore, internal pressure is low discharges owing to device to be dissolved in air in the water-heating system water, accumulates in the inside of emptier, is extracted out by air ejector by exhaust-valve.
Entered the water of emptier inside by water inlet pipe, because density variation, the air accumulation that discharges in the water is extracted out by air ejector at the top of emptier, water then flows into the bottom of emptier, when water increases gradually, utilize the density variation of water and free floating ball, free floating ball is upwards floated, valve is opened automatically, and water is discharged by outlet pipe; When water drained, free floating ball did not have friction and is seated at automatically on the bottom valve, and valve is closed automatically.Bottom valve in emptier inside is in the water seal state always, so played the effect of a secluding air.
The water yield of coming when water-heating system is excessive to cause free floating ball to rise when too fast, and baffle plate and pressure valve begin to have an effect.Emptier bottom water aggregate amount is too much, free floating ball upwards floats, when the water yield gathers to a certain degree, free floating ball touches the baffle plate directly over it, the pressure that this moment, excessive water produced makes the pressure valve that is positioned at the emptier bottom open automatically, water is discharged by pressure valve, this moment, the water surface descended, free floating ball descends along with the decline of the water surface, when free floating ball dropped to the ordinary water level scope, pressure descended, and pressure valve is closed automatically, emptier is normally moved, and water is discharged by outlet pipe.
Method of the present invention is: a kind of air remover is installed in water-heating system, is utilized the density contrast of air and water, the air that accumulates in the emptier top is got rid of through air ejector by exhaust-valve, guarantee the quiet comfortable operation of water-heating system.
The pipeline of the present invention between water inlet pipe and outlet pipe installed a kind of air remover, water inlet pipe is carried the air in the water of coming get rid of by the air remover, make in the water that flows in the outlet pipe not dissolved air, reduce metal parts material corrosion speed, thermic load loss, the water pump loss of flood peak and the conveyance loss of heat carrier heat energy.
