Description
Technical field
The present invention relates to the air remover of a kind of water-heating system, be specifically related to a kind of water-heating system air remover and method that there is separation water and air and air is got rid of function.
Background technology
In the north, water-heating system is the indispensable warming installation of every household. But the premise that water-heating system can safely and effectively be run is to be absent from air in whole system. When system exists air, system can be caused following harm: cause the chemical oxidation effect of metal parts and air in 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, air existing way is mainly static air bag, the air bubble being mingled with and the air three kinds being dissolved in the water. Exhaust apparatus main in water-heating system is divided into high-order air bleeding valve and concentrates air-separating plant two kinds, but when the former needs manually, underaction, the latter is not then provided that of a sufficiently low flow velocity makes to include the air bubble of microvesicle and effectively isolates and get rid of.
Summary of the invention
It is an object of the invention to invent a kind of water-heating system air remover, a kind of method effectively got rid of by water-heating system air is provided, the factor eliminating of metal parts material corrosion speed, thermic load loss, the water pump loss of flood peak and heat carrier heat energy conveyance loss will be affected, thus improving service life and the heat transfer efficiency of metal material, it is ensured that the quiet comfortable operation of water-heating system.
In order to achieve the above object, assembly of the invention specifically includes that water inlet pipe, free floating ball, pressure valve, baffle plate, exhaust-valve, air ejector and outlet pipe.
The water inlet pipe of emptier is connected with water-heating system, and the water in water-heating system is entered in emptier by water inlet pipe.
Having a free floating ball inside emptier, free floating ball is connected with outlet pipe by valve. Free floating ball is the rustless 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 freely up and down float, and will not produce frictionally damage with valve.When there being water to enter, utilizing the buoyancy of ball float and the different of gravity so that ball float floats up, the water in emptier is discharged by outlet pipe by valve.
After water is entered emptier inside by water inlet pipe, owing to the caliber of water inlet pipe is much smaller than the internal diameter of emptier internal cavity, from fluid mechanics principle: owing to can not interrupt when fluid flows in the duct, can not pile up, so the water quality flowing through the arbitrary cross section of pipeline within the unit interval is equal, lower sequential continuity (conservation of mass) equation is namely had to set up:
��1S1V1=��2S2V2In=constant formula: �� density; S pipe section is amassed; V flow velocity
It can be inferred that: the flow velocity that caliber is slightly located is less, and caliber carefully to locate flow velocity bigger, say, that air velocity and pipeline section area are inversely proportional to greatly. Therefore, when water is entered in emptier by water inlet pipe, the flow velocity of water reduces, and is internally formed a relatively low region of flow velocity in emptier. The air bubble including microvesicle being mixed in water in this region has time enough rising to form bigger bubble, and finally breaks, and being wrapped in air therein can discharge, and due to the difference of water Yu air, air can be gathered in the top of device.
At the top of emptier equipped with exhaust-valve and air ejector, air bubble the air being gathered in emptier top that is that discharge and that be mingled with in water is extracted out by air ejector by exhaust-valve. At air ejector duration of work, the pressure within emptier is very low. From Henry's law: at a certain temperature, certain gas concentration in the solution is directly proportional to the balance pressure of this gas on liquid level. And this law is useful too for solute volatile in weak solution, experiments show that, when only gas dissolubility in a liquid is not significantly high, this law is only correct. In general, main component nitrogen and oxygen dissolubility in water in air are only small, formed solution belong to weak solution scope. Therefore, the air being dissolved in water-heating system water discharges owing to device internal pressure is low, is gathered in the inside of emptier, is extracted out by air ejector by exhaust-valve.
The water within emptier is entered by water inlet pipe, due to density variation, the air accumulation discharged in 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, make free floating ball float up, valve automatically turns on, and water is discharged by outlet pipe; When water drains, free floating ball is seated on bottom valve automatically without friction, and valve is automatically switched off. It is constantly in water seal state, so serving the effect of an isolation air at the bottom valve within emptier.
When the water yield that water-heating system comes is excessive cause free floating ball rise too fast time, baffle plate and pressure valve start to have an effect. Emptier bottom water aggregate amount is too much, free floating ball floats up, when the water yield gathers to a certain degree, free floating ball touches baffle plate directly above, the pressure that now excessive water produces makes the pressure valve being positioned at bottom emptier automatically turn on, water is discharged by pressure valve, now the water surface declines, free floating ball declines along with the decline of the water surface, when free floating ball drops to ordinary water level scope, pressure declines, and pressure valve is automatically switched off, emptier is properly functioning, and water is discharged by outlet pipe.
The method comprise the steps that and a kind of air remover is installed in water-heating system, utilize the density contrast of air and water, will accumulate in the air at emptier top and got rid of through air ejector by exhaust-valve, it is ensured that the comfortable operation of peace and quiet of water-heating system.
Present invention pipeline between water inlet pipe and outlet pipe is installed a kind of air remover, got rid of by the air in the water that water inlet pipe conveying is come by air remover, make insoluble air in the water in inflow outlet pipe, reduce metal parts material corrosion speed, thermic load loss, the water pump loss of flood peak and heat carrier heat energy conveyance loss.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Referring to Fig. 1, water inlet pipe 1 is connected with the entrance of emptier 9, emptier 9 is connected with outlet pipe 5 by valve 4, in emptier 9, free floating ball 2 is connected by valve 4 with outlet pipe 5, and pressure valve 3 is in the lower section of emptier 9, and baffle plate 7 is the arc structure top at free floating ball 2, exhaust-valve 6 is arranged on the top of emptier 9, and air ejector 8 is connected with exhaust-valve 6 by pipeline.
After the water in water inlet pipe 1 is input to emptier 9, due to the density variation of water Yu air, water is gathered in the bottom of emptier 9, and air is then gathered in top. When water enters the entrance of emptier 9, become suddenly due to caliber and make greatly the flow velocity of water reduce, be therefore internally formed a relatively low region of flow velocity in emptier 9. In this region, the air bubble including microvesicle etc. being mixed in water has time enough rising form larger bubble and finally break, and air discharges the top being gathered in emptier 9. It addition, according to Henry's law: at a certain temperature, in subtle solution, the partial vapour pressure of solute is directly proportional to solution concentration. Therefore the air in emptier 9 is constantly extracted out by air ejector 8, be dissolved in the air in water and also can evaporate and extracted out by exhaust-valve 6 by air ejector 8, reduce water air content.
Inside emptier, the diameter of free floating ball is more smaller than emptier cavity size, can freely up and down float. Water enters after bottom emptier 9, density variation due to water Yu free floating ball, free floating ball can along with the increase of water, and liquid level rises, and free floating ball 2 floats up, valve 4 is opened, water is discharged by valve 4 in outlet pipe 5, after water discharge, free floating ball 2 automatically take a seat with on the valve nozzle of valve 4, valve 4 is automatically switched off, free floating ball 2 but also start the cycle over work after having not only water to enter bottom. Owing to valve 4 is in water seal all the time, therefore outlet pipe will not there is air to enter, serve the effect of an air insulated.
When in water inlet pipe, flow is excessive in 1, water level rises, and free floating ball is raised above, and can be ended by free floating ball when arriving certain altitude backboard 7, emptier internal pressure rises, after arriving certain pressure, pressure valve 3 automatically turns on, and water is discharged by pressure valve 3, regulate the flow of water in water inlet pipe 1, making water level and pressure return to normal range, pressure valve 3 is closed, and emptier 9 is properly functioning.
