Description

TECHNICAL FIELD

[0001] The utility model relates to the pressure tank field, especially a kind of pressure tank of full-automatic dynamic adjustment water pressure. BACKGROUND

[0002] Water pressure tank is to utilize the compressibility of air in tank to regulate and store water and keep the required pressure.When water pump starts, it will supply water to pipe network, and the excess water is stored in tank, so that the water level in tank rises, and the air in tank is compressed, and the pressure increases accordingly.When the pressure in tank reaches the upper limit pressure value, power supply will be cut off, and pump will be stopped.When user continues to use water, the compressed air in tank will press the water in tank into pipe network, and the water level drops, and the air pressure in tank also decreases accordingly.When it decreases to the lower limit pressure value, water pump will start working again.

[0003] Water pressure tank has two types of air supplementing type and diaphragm type:

[0004] Air supplementing type: air directly contacts with water, and after a period of time, air decreases due to leakage and dissolution in water, so that the regulated water gradually decreases, and water pump starts frequently, so air supplementing is needed regularly.Air supplementing methods include air compressor air supplementing, water injector air supplementing and regular air release air supplementing.

[0005] Diaphragm type: air and water are separated, water is inside rubber (plastic) bag, and the gap between the outside and tank body is pre-filled with inert gas, which is generally nitrogen gas.This type of pressure tank has no air dissolution and water loss problem, and can be filled with air once, and used for a long time without setting air compressor.

[0006] The existing water pressure tank, whether air supplementing type or diaphragm type, is stepless speed change to target value pressure stabilization, and cannot dynamically output water pressure. INVENTION CONTENTS
