Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pressure tanks, in particular to a pressure tank with an air bag balance support structure. Background Art
[0002] The pressure tank buffers system pressure fluctuations, eliminates water hammer and plays a role in stabilizing pressure and unloading. When the water pressure in the system changes slightly, the automatic expansion and contraction of the pressure tank airbag will have a certain buffering effect on the change in water pressure and can ensure the stability of the system's water pressure.
[0003] The pressure tank is used in the closed water circulation system to balance the water volume and pressure, avoiding frequent opening of the safety valve and frequent water replenishment of the automatic water replenishment valve. In addition to accommodating the expansion water, the expansion tank can also serve as a water replenishment tank. The expansion tank is filled with air to obtain a larger volume to accommodate the expansion water. The high and low pressure expansion tanks can use their own pressure to replenish water to the pressure stabilization system in parallel.
[0004] The main components of the water purifier are pre-filter, high and low pressure switch, solenoid valve, one-way valve, waste water ratio, booster pump, RO membrane, post-filter, faucet to form a filtering device to produce pure water for people to drink. The water pressure is affected by many external interference factors during the water production process, which solves the problem of unstable water output from the water purifier.
