2,size
Applicable to thermal systems (boilers, air conditioners,heat pumps, water heaters,etc.), constant pressure systems (frequency conversion water supply,constant pressure water supply,etc.),solar energy systems.
1. Diaphragm type pressure expansion tank is an energy storage device composed of a steel shell and a rubber diaphragm liner.The rubber diaphragm completely separates the water chamber and the air chamber,and when the external pressure water fills the bladder of the diaphragm pressure water tank At that time, the air sealed in the tank is compressed. According to Boyle's gas law, the volume of compressed gas becomes smaller, the pressure rises to store energy, and the compressed gas expands to push the water in the rubber diaphragm out of the tank.
2. A closed vessel in which the diaphragm divides the gas (usually nitrogen) and the system water into two parts,it is used in the heating and air-conditioning watertight systems to absorb the amount of water that expands when heated, and to balance the system water volume and pressure,the pressure increases,the pressure is higher than the pressure of the pre-charged nitrogen,and the heated and expanded water enters the expansion tank.
3. The expansion tank is used in the closed water circulation system to balance the water volume and pressure, avoid frequent opening of the safety valve and frequent replenishment of the automatic replenishment valve.
1,working principle
(1) Nitrogen gas sealed in the tank is compressed when external pressure water enters the balloon of the expansion tank.
(2) According to Boyle's gas law,the pressure of the gas is increased after the gas is compressed,until the gas pressure in the expansion tank is equal to the water pressure.
Into the water.
(3) When the water loss pressure decreases,the gas pressure in the expansion tank is greater than the water pressure. At this time,the gas expansion squeezes the water in the balloon to the system until the gas pressure.
When the pressure of water and water agree again, stop the drainage.
2,the structure description
| (1) It consists of four parts, tank, balloon,inlet/outlet,and air inlet (2) The pre-inflated body between the balloon and the tank is filled at the factory.Need to add gas yourself. (3) The biggest difference between the bladder expansion tank and the diaphragm expansion tank is. (4) The bladder of the bladder expansion tank is water and the upper part of the diaphragm expansion.tank For the gas, the lower part is water. (5) Capsule only flange and balloon contact with water if flange The disk is selected as stainless steel flange,the life of the expansion tank will be greatly extended long. |
3,installation
In thermal systems such as air conditioners, boilers, heat pumps,etc. are generally installed at the return end of the system.
The water supply system is generally installed at the outlet of the water pump.
