Description

Technical Field

[0001] The utility model relates to the technical field of pressure tanks, in particular to a split pressure tank assembled by upper and lower cover bodies. Background Art

[0002] The pressure tank is used in a 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. The control of each point of this device is interlocking reaction, automatic operation, small pressure fluctuation range, safe and reliable, energy-saving, and good economic effect.

[0003] The pressure tank uses the compressibility of the air in the tank to regulate and store water and keep it at the required pressure, so it is also called air pressure water supply equipment, which is equivalent to a water tower and a high-level water tank. Since its water supply pressure is maintained by the compressed air in the tank, the installation height of the tank is not limited.

[0004] At present, there are various water treatment devices on water purifiers, such as reverse osmosis water purifiers, ultrafiltration water purifiers, nanofiltration water purifiers, ceramic water purifiers, etc. Among them, reverse osmosis water purifiers have been vigorously promoted for their advantages of high removal accuracy, good removal effect, and good water quality. The main components of the water purifier are pre-filters, high and low pressure switches, solenoid valves, one-way valves, wastewater ratios, booster pumps, RO membranes, post-filters, and faucets to form a filtration device to produce pure water for people to drink. In the process of water production, the water pressure is subject to many external interference factors, which solves the problem of unstable water output from the water purifier.
