The floor-standing expansion tank has the same function as the capsule water supply regulator

The floor-standing expansion tank works the same as the capsule water supply regulator.

When the floor-mounted expansion tank is used in the system, because the system pressure is higher than the pressure of the pre-inflated body, a part of the working medium enters the airbag (in the case of the diaphragm, it enters the tank) until a new balance is reached, when the system The pressure rises again, the system pressure is again greater than the pressure of the pre-inflated body, and a part of the medium enters the capsule. The gas between the compression bladder and the tank body is increased by the compression pressure. When it rises to the same pressure as the system, The medium stops entering. Conversely, when the system pressure drops, the medium pressure in the system is lower than the gas pressure between the capsule and the tank. The water in the airbag is squeezed into the system by the gas extrusion, so that the system pressure rises until the system working medium The pressure is equal to the gas pressure between the bladder and the tank, and the water in the bladder is no longer supplied by the external system to maintain a dynamic balance.

The floor-standing expansion water tank and the capsule water supply voltage regulator have the same function. The 2000*1.0 floor-type expansion water tank adopts the system static pressure as the initial pressure head of the design in the expansion tank, and adopts the pressure to ensure that the hot water in the system is not vaporized as the expansion tank. Terminal pressure head. In the initial operation, the make-up water pump is first started to fill the water in the system and the pressure tank, and the excess water is squeezed into the capsule after the system is full. Because of the incompressibility of water, as the amount of water continues to increase, the volume of the water chamber continues to expand and the chamber is compressed, and the pressure inside the tank is also constantly increasing. When the pressure reaches the design pressure, the make-up pump is turned off by the pressure controller. When the water in the system is heated to expand and the system pressure rises above the design pressure, the excess water is discharged through the safety valve to the make-up tank. When the water in the system is reduced due to leakage or temperature drop, the system pressure is reduced. The water in the water is continuously pressed into the pressure drop loss of the pipe network replenishing system. When the system pressure reaches the low pressure allowed by the design, the water pump is restarted by the pressure controller to replenish the pipe network and the pressure tank, and so on.

The main function of the floor-type expansion water tank and the capsule water supply voltage regulator

1. One-time inflation can be used for a long time.

2. The tank body is a closed device. The gas and water are not in contact, which can ensure that the water quality is not polluted by the outside and does not corrode the tank.

3, less floor space, investment, fast installation, easy operation and maintenance.

4. Save the high water tank in the building and save structural investment.

5. The water tank acts as a buffer to eliminate the water hammer impact on the pipe network.

6, automatic control, reliable operation.
