After the equipment is installed on site and connected with other equipment pipelines, a ball valve of the pressure regulating tank device is opened to keep the equipment pressure at normal pressure (at the moment, the limit switch is changed from a normally open state to a normally closed state).

And finally, when the heating season is over, the equipment stops running completely, the volume of the acting oil due to thermal expansion and contraction is reduced due to the reduction of the oil temperature, so that external air enters the pressure regulating tank device through the air inlet and outlet pipe, the oil in the same pressure regulating tank device is pressed into the communicating pipe, gas in the communicating pipe enters the expansion cavity, and the oil in the expansion cavity flows back to the oil cavity, so that the whole system is still in a normal pressure state.
In the utility model, once the ball valve fails, the limit switch is in a normally closed state, so that the pressure control component can play a role, and the pressure in the heater is controlled to be at a safe level and alarm processing is performed. The utility model can remotely perform all local functional operations on the equipment, and can naturally perform partial functional limitation according to the account authority.
