Description
Technical Field
The utility model relates to a water purifier field, in particular to water tank of water purification machine.
Background
When the water purifier works, water flow passes through the reverse osmosis membrane to filter out fine harmful impurities: bacteria, viruses, reflective substances and heavy metals, organic compounds, etc.
From the original view of the water purification machine, only pure water passes through the reverse osmosis membrane, and impurities are removed outside and are discharged. Because the water yield of the water purification machine is too small, the requirement of taking water at any time by a user can not be met, when the user does not take water, the water purification machine works as well, the prepared pure water is stored in the pressure water tank firstly, when the user needs water, the pure water is directly output from the pressure water tank to the outside, and the user does not need to wait for water preparation in time. The pressure water tank of the water purifier plays a role in balancing water quantity and pressure, and frequent opening of the safety valve and frequent water replenishing of the automatic water replenishing valve are avoided.
The pressure water tank is divided into a plastic pressure water tank, a carbon steel pressure water tank and the like in material. The existing pressure water tank is generally composed of a tank body, an air bag, a water nozzle, a valve core and the like. When the air bag is empty, the pressure in the air bag is about 0.5 Kg. After the pure water is slowly injected into the barrel, the air in the air bag is compressed, the air pressure is gradually increased until the pressure of the air bag reaches the set pressure of the high-pressure switch of the water purifier, and the machine is stopped. When the pure water tap is opened, the pure water stored in the pressure water tank can be pressed out by the air pressure in the air bag.
When water is filled into the barrel through an external pipeline, because the water pressure is gradually increased, the air pressure also rises along with the water pressure, the pressure of the water pressure and the air pressure is always equal, if a high-pressure switch at the front end of the water storage pressure water tank breaks down, two independent water high-pressure areas and air high-pressure areas can be formed in the pressure water tank and are easy to burst, and high-pressure gas and liquid generate great impact force at the moment of breaking the pressure water tank, so that certain threat exists on the safety of a human body.
Therefore, in the selection of the pressure water tank, the water purifier manufacturer can make two choices:
