Abstract
A simple and reliable water system automatic water filling device comprises a filter, a magnetic valve, a check valve and a relief valve. The utility model is characterized in that the utility model uses an artesian water source as the recharging water source which is connected in the water system directly. When the water system operates, the magnetic valve opens. Without water or lack of water, the artesian water source of the utility model pushes the check valve depending on the water pressure, then the water system is filled with water automatically via the filter, the magnetic valve, and the check valve until the water pressure in the water system reaches the same level with the water pressure in the artesian water source. When the water system does not lack of water, the check valve is closed depending on the spring pressure, and the water system is separated with the recharging water source, further the automatic water filling is achieved. When the water system stops the operation, the magnetic valve is closed. The check valve can not have the conducting in negative direction, the water in the water system can not flow back to the artesian water source, and thereby the condition that the artesian water source will not be polluted is ensured. The utility model has the advantages of simple structure, small volume, and reliable operation. Under mass conditions, the utility model can replace the extension water tank.
Description
The utility model relates to the improvement of water system automatic water supplement method.
Water system in the air-conditioning generally is divided into open type water system and closed Water System.The pipeline of open type water system communicates with atmosphere, the pipeline of closed Water System then with atmospheric isolation.
The open type water system communicates with atmosphere owing to pipeline, thus circulation water oxygen level height, corrosive equipment and pipe network; And dust in air, bacterium, soluble gas very easily enter in the recirculated water, makes that microorganism breeds in a large number in the water, forms biological sludge, causes line clogging or produce water hammer.The water pump pressure head of this outward opening water system except that need overcome the resistance of pipe network, also need water is risen to certain certain altitude, so pump energy consumption is bigger.Based on above reason, in Air-conditioning Engineering, particularly in the chilled water loop, seldom adopt the open type water system in recent years.
Closed Water System is compared with the open type water system, and not only pump energy consumption is few, and the possibility of equipment and piping corrosion is little.But because the needs of moisturizing, and the containment water temperature changes the needs that the water volume that causes changes, so in closed Water System expansion tank need be set, the expansion tank operated by rotary motion is at the peak of water system.
For some small central air conditionings, as residential central air conditioning, the ceiling of when fan coil is installed, need trying one's best, thus make expansion tank be difficult to find suitable installation site, expansion tank is installed sometimes even nowhere.
The purpose of this utility model provides a kind of simple in structure, automatic water-replenishing device that volume is small and exquisite, reliable, replaces expansion tank.
The technical solution of the utility model is as follows:
The water system automatic water-replenishing device is made up of strainer, electromagnetic valve, flap valve, safety valve.Be characterized in using the pressure water source directly to receive in the water system as the moisturizing water source, when water system moves, electromagnetic valve is opened, if do not have water or lack of water in the water system, be the pressure that hydraulic pressure in the water system is lower than the pressure water source, this moment, flap valve was backed down by hydraulic pressure in the pressure water source, the pressure water source will be by the moisturizing in the trend water system of strainer, electromagnetic valve and flap valve, hydraulic pressure in water system equates with the hydraulic pressure in pressure water source, be that water system is no longer during lack of water, flap valve cuts out by spring pressure, and water system and moisturizing water source separate, and automatic water supplement is finished.After water system is out of service, closed electromagnetic valve.
If during the water system operation, cut off the water supply in the pressure water source, promptly the hydraulic pressure in the water system is higher than the hydraulic pressure in pressure water source, though this moment, electromagnetic valve was an opening, but flap valve can not reverse conducting, and the water in the water system can't flow back to the pressure water source, thereby guarantees that the pressure water source can not pollute.
No matter whether water system moves, when if the hydraulic pressure in the water system is higher than setting value, no matter which kind of state electromagnetic valve is, because flap valve can not reverse conducting, the water of water system will overflow from safety valve, hydraulic pressure in water system is lower than setting value, thereby guarantees the security of operation of water system, also guarantees can not pollute the pressure water source.
The utlity model has advantage simple in structure, that volume is small and exquisite, reliable, in most of the cases can replace expansion tank.
Describe the utility model in detail below in conjunction with accompanying drawing 1.
As shown in Figure 1, directly receive in the water system as the moisturizing water source in pressure water source 1, and strainer 2, electromagnetic valve 3, flap valve 4 are cascaded, and are installed in the inlet in pressure water source 1, and safety valve 5 can be installed in the optional position in the water system.
When water system moved, opening is opened and kept to electromagnetic valve 3; After water system was out of service, electromagnetic valve 3 cut out.
If during the water system operation, there are not water or lack of water in the water system, be the pressure that hydraulic pressure in the water system is lower than pressure water source 1, because electromagnetic valve 3 is openings, this moment, flap valve 4 was backed down by hydraulic pressure in pressure water source 1, pressure water source 1 will be by strainer 2, electromagnetic valve 3 and flap valve 4 moisturizing in the trend water system, hydraulic pressure in water system equates with the hydraulic pressure in pressure water source 1, be that water system is no longer during lack of water, flap valve 4 cuts out by spring pressure, water system and moisturizing water source 1 separate, and automatic water supplement is finished.
If during the water system operation, cut off the water supply in pressure water source 1, promptly the hydraulic pressure in the water system is higher than the hydraulic pressure in pressure water source 1, though this moment, electromagnetic valve 3 was openings, but flap valve 4 can not reverse conducting, and the water in the water system can't flow back to pressure water source 1, thereby guarantees can not pollute pressure water source 1.
No matter whether water system moves, when the hydraulic pressure in the water system is higher than setting value, no matter which kind of state electromagnetic valve 3 is, because flap valve 4 can not reverse conducting, the water of water system will overflow from safety valve 5, hydraulic pressure in water system is lower than setting value, thereby guarantees the security of operation of water system, also guarantees can not pollute pressure water source 1.
