5, the specific embodiment
Explain below doing with regard to 1 pair of pressure water supply jar automatic air supply device of the present utility model of accompanying drawing below.
As shown in Figure 1, pressure water supply jar automatic air supply device of the present utility model is by pressure water supply jar (4), level switch (8), tonifying Qi electromagnetic valve (13), air supply tank (14), sluicing electromagnetic valve (15) and electric control box (6) are formed, pressure water supply jar (4) directly is installed on the pressure water supply pipeline (1), and between pressure water supply jar (4) and pressure water supply pipeline (1), be provided with valve (2), install with convenient, maintenance, be provided with draining valve (3) between valve (2) and the pressure water supply jar (4), be equiped with electric control box (6) on the pressure water supply jar (4), pressure water supply jar (4) top is provided with pressure meter (7), the bottom of pressure water supply jar (4) is connected by pipeline with air supply tank (14) bottom, and tonifying Qi electromagnetic valve (13) is housed on pipeline, air supply tank (14) bottom is provided with sluicing electromagnetic valve (15), air supply tank (14) top is provided with the air inlet port that is communicated with outside air, and at air inlet port place installing air filter (11) and gas stoper (12), air supply tank (14) highest point adopts blowdown pipe (10) to be connected with pressure water supply jar (4) 200~400mm place more than the highest design water level, and on blowdown pipe (10), be provided with the one way stop peturn valve (9) that flows to pressure water supply jar (4), the highest design water level place inner at pressure water supply jar (4) is provided with level switch (8), level switch (8), tonifying Qi electromagnetic valve (13) and sluicing electromagnetic valve (15) are wired to electric control box (6) respectively, and are provided with time controller (5) in the electric control box (6).
During operate as normal, sluicing electromagnetic valve (15) cuts out, tonifying Qi electromagnetic valve (13) is opened, the current of pressure water supply pipeline (1) enter pressure water supply jar (4), and the air in the compression gas-pressure water supply tank (4), because air contacts with water and can make air water-soluble, air in the pressure water supply jar (4) will reduce gradually, water level rises thereupon, when the water level of maximum working pressure in the pressure water supply jar (4) surpasses the highest design water level of level switch (8), sluicing electromagnetic valve (15) is opened, tonifying Qi electromagnetic valve (13) cuts out, air supply tank (14) sluices, and it is air-breathing by air filter (11) and gas stoper (12), after water emptying in air supply tank (14) is filled air, sluicing electromagnetic valve (15) cuts out, tonifying Qi electromagnetic valve (13) is opened, at this moment, and by interior water level of pressure water supply jar (4) and the interior water-head of air supply tank (14), air in the air supply tank (14) is mended in the pressure water supply jar (4), so just finished a tonifying Qi process.If the water level of the pressure water supply jar (4) after tonifying Qi still is in the highest design water level of level switch (8) when above, then repeat above-mentioned tonifying Qi process; When the water level of pressure water supply jar (4) is in the highest design water level of level switch (8) when following, then recover normal operating conditions, sluicing electromagnetic valve (15) cuts out, tonifying Qi electromagnetic valve (13) is opened.So repeat work, to finish the automatic tonifying Qi process of pressure water supply jar (4).
