[0002] Automatic pressure regulating steam boiler is a kind of steam boiler capable of automatically adjusting steam pressure.The working principle of automatic pressure regulating steam boiler is based on thermodynamics principle, and the heat released by fuel combustion is used to heat water to boiling state, thereby generating steam, and the amount of generated steam is related to the combustion state and other factors, when the steam gathers more to cause the high pressure in furnace, it needs to release steam to balance the pressure in furnace, when the pressure in furnace is low, it needs to supplement steam or other gas to balance the pressure in furnace.

[0003] The existing automatic pressure regulating device is generally divided into two parts, when the pressure is low, it needs to increase fuel combustion to increase heat, so that steam output increases, so that the pressure increases to balance the pressure in furnace. When the pressure is high, it needs to release steam to balance the pressure in furnace. The existing balance pressure reducing valve is provided with spring-fixed piston at valve port, when the pressure in furnace is high, the piston is lifted upward by pressure, so that the valve port is smooth to make steam spray out. But since there is only one kind of adjustment mode, i.e. piston port opening condition, the pressure regulating device is not sensitive enough, and cannot achieve step adjustment. In addition, since the piston is closed with valve port for a long time, it even appears to be bonded together after a long time, so that it cannot reduce pressure, and the pressure regulating device fails. In view of the above situation, the utility model provides an automatic pressure regulating steam boiler to solve the above problems. UTILITY MODEL CONTENTS
