Description

Device for keeping water in air pressure tank fresh
Technical Field
The utility model relates to a water supply equipment's technical field especially relates to a keep the device that the water body is bright and alive in the atmospheric pressure jar.
Background
The secondary water supply equipment is various in structure and control mode, and the structure is more in the form of 'a water pump set + a variable-frequency electric control cabinet'. Generally, different from the regular and quantitative supply of domestic water, the domestic water supply equipment has a large change curve of domestic water amount and obvious time characteristics, so that the domestic water supply equipment has the advantages of 'multi-purpose water and more power consumption'; less water consumption and less power consumption.
The atmospheric pressure jar is the prerequisite that the water pump can get into the sleep, utilizes the minimum nature of the compressibility of water, stores up water in the jar with external force, and gas receives compression pressure and risees, and compressed gas inflation can get rid of water when external force disappears, because the compression ratio of water is less than gas far away, has the decline that can cause pressure by a wide margin of the leakage of low discharge when the pipe network, can make the water pump frequently start, if the power frequency pump directly supplies water to the user, just must be equipped with the atmospheric pressure jar, alleviates the water pump and frequently starts.
The existing air pressure tank mainly comprises a valve cover, an inflation inlet, an air bag, a tank body and a flange plate, when the existing air pressure tank is connected to a water system, the existing air pressure tank mainly plays a role of an energy accumulator, when the pressure of system water is greater than the pressure of nitrogen between the tank body and the air bag, the system water can be squeezed into the air bag under the action of the system pressure, and thus the nitrogen between the tank body and the air bag can be compressed, so that the volume of the existing air pressure tank is reduced, and the pressure is increased; and secondly, the containing space of the whole water of the system is increased, so that the pressure of the system is reduced, and water inflow is stopped until the pressure of the system water and the pressure of nitrogen between the tank body and the air bag reach new balance. When the water pressure of the system is smaller than the gas pressure in the tank, the water in the air bag is extruded out under the pressure effect of the nitrogen between the tank body and the air bag and is fed back to the system, the volume of the water of the system is reduced, the pressure is increased, the volume of the nitrogen between the tank body and the air bag is increased, the pressure is reduced until the volume of the nitrogen and the air bag reach new balance, the water stops being extruded back to the system from the air bag, and the pressure tank plays a role in regulating the pressure fluctuation of the.
In the in-service use process, it is very little to discover the water pressure fluctuation in the atmospheric pressure jar, because of the water pressure fluctuation is little, the corresponding reduction of the water yield of business turn over atmospheric pressure jar, and the atmospheric pressure jar commonly used intake water, it is in same department to go out water, this just leads to only having the hydroenergy that is close to business turn over water mouthful department in the atmospheric pressure jar to exchange with the water in the water supply pipe network, most water in the atmospheric pressure jar can not obtain the replacement for a long time, easily form the stagnant water, and the stagnant water of detention time overlength breeds the microorganism easily, thereby make water corruption rotten, cause secondary pollution to the.
