Background
At present, the installation of a constant-pressure water replenishing device on automatic water supply equipment or water tank equipment is an important improvement measure, wherein the constant-pressure water replenishing device is used for pressurized water supply of production, fire protection and living systems and is generally called as a bag type automatic water supply device. The expansion water tank is used as a pressure-stabilizing expansion water-replenishing device in a heating and air-conditioning system and is generally called as a bag-type floor-type expansion water tank. The constant pressure water supplementing device adopts the static pressure of the system as a designed initial pressure head in the expansion water tank, and simultaneously adopts the pressure for ensuring that hot water in the system is not vaporized as a pressure head of a movable terminal in the expansion water tank.
In the prior art, when the constant-pressure water replenishing device initially operates, the water replenishing pump is started to fill water into the water chamber in the system and the air pressure tank, and after the system is filled with water, redundant water is squeezed into the capsule. Because of the incompressibility of water, the volume of the water chamber is continuously enlarged along with the continuous increase of the water quantity to compress the air chamber, and the pressure in the tank is also continuously increased. When the pressure reaches the design pressure, the water replenishing pump is closed through the pressure controller. When the water in the system is heated and expanded to enable the system pressure to rise and exceed the design pressure, redundant water is discharged to the water replenishing tank through the electromagnetic valve for recycling, when the system pressure exceeds the working pressure of a pipe network or equipment, the safety valve is opened to play a role in protecting the pipe network and the equipment, when the water in the system is reduced in size due to leakage or temperature reduction, when the system pressure is reduced, the water in the capsule is continuously pressed into the pressure drop loss of the pipe network replenishing system, when the system pressure reaches the lowest pressure allowed by design, the water replenishing pump is restarted to replenish water into the pipe network and the air pressure tank through the pressure controller, and the operation is repeated.
The traditional constant pressure water replenishing machine set generally transports parts, is installed on site, increases the construction difficulty and has poor reliability. The expansion volume of the common floor type expansion water tank is realized by the contraction and expansion of the capsule, the effective available volume of the tank body is only 20% -30% of the total volume of the tank body, the tank body is huge, the expansion part and the air pressure stabilizing part are not separately arranged, air and water in the tank body are contacted, the water quality is easily polluted, the volume utilization rate of equipment is low, the volume and height of the whole machine are large, and the construction arrangement and installation are complex.
