DY type constant pressure device made in China

Improve

Dy type constant pressure device is an ideal replacement product for the expansion water tank set at the high position of the water heating system. Based on years of experience and technical strength in manufacturing and developing water heating equipment, the factory has successfully developed dy type constant pressure device. The device adopts microprocessor to implement full-automatic control, which is sensitive, and the complete set of equipment is convenient for design, selection, installation and use.

Basic functions

The constant pressure device has three basic functions of expansion water tank set at common high position:

(1) Expansion and contraction of water body in the regulating system caused by temperature fluctuation - expansion and contraction;

(2) Make the pressure of a certain point of the system constant - constant pressure;

(3) Make up water to the system in case of leakage - make up water;

Another special function of the device

(1) The periodic exhaust gas is the gas separated by water heating.

Scope of application

(1) Hot water heating system with t ≤ 120 ℃

(2) Hot water heating system with t ≤ 130 ℃

(3) Double pipe and three pipe air conditioning and water transfer system in winter and summer

(4) Domestic hot water supply system without open heat storage tank
