It is a larger, more complete model, and more complete supporting expansion tank and airbag manufacturer in China.

Structure and working principle of expansion tank, air pressure tank, pressure tank and surge tank:
The bladder expansion tank is mainly composed of gas door Cover, inflation port, air bag, carbon steel tank body flange When it is connected to the water system, it is mainly used as an accumulator. When the system water pressure is greater than the nitrogen pressure between the carbon steel tank of the expansion tank and the air bag, the system water will be squeezed into the air bag of the expansion tank under the effect of the system pressure. First, it will compress the nitrogen between the tank and the air bag, reducing its volume and increasing its pressure; Second, it will increase the capacity of the whole water in the system and reduce the system pressure until the system water pressure and the nitrogen pressure between the tank and the air bag reach a new balance. When the system water pressure is less than the gas pressure in the expansion tank, the water in the air bag will be squeezed out under the pressure of nitrogen between the tank and the air bag and fed back to the system. The system water volume decreases and the pressure rises, and the nitrogen volume between the tank and the air bag increases and the pressure drops until the two reach a new balance. The water stops squeezing back to the system from the air bag, The stainless steel expansion tank plays a role in regulating the pressure fluctuation of the system.

Applicable scope of expansion tank, air pressure tank, pressure tank and surge tank:
Expansion tanks are widely used in mid point air conditioners, boilers, fire protection, water treatment, water heaters and other fields; The expansion tank is also used for stabilizing the circulating water of the midpoint air conditioning system, the expansion system of steam water supply, stabilizing the circulating water supply of the heating system, stabilizing the water supply of the fire water supply system, stabilizing the variable-frequency water supply, boiler water supply, pneumatic water supply and other occasions.

Functions of expansion tank, air pressure tank, pressure tank and surge tank:
The expansion tank plays a role in balancing water volume and pressure in the closed water circulation system, avoiding frequent opening of safety valve and frequent water replenishing of automatic water replenishing valve. In addition, in the water system, the expansion tank can also reduce the frequent starting of the water pump, which can be used to absorb the water hammer impact caused by the opening and closing of valves and water pumps in the system, and a small amount of water supplement at night makes the main pump of the water supply system sleep, thus reducing the power consumption and prolonging the service life of the water pump.

Features of expansion tank, air pressure tank, pressure tank and surge tank:
The internal airbag structure of the expansion tank ensures that the water does not contact the tank wall, so there is no rust inside the expansion tank wall and no condensation outside the expansion tank, and the service life is greatly extended. In the refrigeration and HVAC system, compared with the traditional expansion tank, the expansion tank has many advantages, such as easy installation (not installed at a higher point), small space occupation, no secondary pollution, and long service life.

Installation of expansion tank, air pressure tank, pressure tank and surge tank:
In the heating system, it is recommended to install the expansion tank at the place where the system water temperature is relatively low, generally at the return end of the system and the cold water inlet end of the heat storage tank. The expansion tanks of 24L and below can be directly connected to the system pipeline due to their light deadweight. In order to avoid large load on the system pipeline caused by water inflow and dead weight of the expansion tank during operation, the expansion tank with a capacity of more than 24L is equipped with a tripod support. The expansion tank can be connected to the system with a metal hose, and the feet of the expansion tank can be fixed with buried screws to ensure stability during use.

A safety valve shall be installed near the expansion tank to avoid damaging the expansion tank and other parts of the system when the system pressure is abnormal.

In the heating and air-conditioning closed cycle system, the expansion tank cannot be installed at the water outlet of the water pump, which may cause cavitation of the water pump. 4. The expansion tank has been delivered from the factory, and the pre charging pressure has been set, which is generally between 1bar and 4bar. If the user thinks that the pressure is not suitable for the operation of the system, he must use a pressure gauge to test while charging and bleeding, or contact the supplier.
