The membrane 2 is arranged in the air cavity of the shell 1, the outer wall of the membrane is provided with a magnetic sheet 21 which is matched with the Hall element and can detect the displacement, and the inner cavity of the membrane 2 can store water and is provided with a water inlet and outlet port 22.
The cylinder 6 is provided on the housing 1, and a piston 61 that always blocks the adjustment port is provided on the inner wall of the cylinder 6.
The motor 4 is arranged on the cylinder body 6, the power output end of the motor is connected with a lead screw 41, specifically, one end of the cylinder body 6 is provided with a mounting plate 43, the motor 4 is arranged on the mounting plate 43, and a stepping motor is preferably adopted.
The lead screw 41 extends into the cylinder 6 and is provided at its end with a nut 42 cooperating with the lead screw 41, the nut 42 being connected to the piston 61 and being capable of driving the piston 61 to move back and forth relative to the inner wall of the cylinder 6.
The inner wall of the cylinder 6 is provided with a guide rail 62 which cooperates with the piston 61. The outer wall of the cylinder 6 is provided with an outer cover 3, the motor 4 is positioned in the outer cover 3, and the periphery of the outer cover is provided with a heat dissipation hole 31.
As shown in fig. 1, the hall element in the present embodiment includes a first hall element 71 and a second hall element 72, and the first hall element 71 is located below the second hall element 72. Two hall elements can provide more accurate and rich control.

When the water pressure in the pipe of the circulation loop needs to be reduced, the motor drives the piston to move upwards, so that the air pressure in the shell is reduced, more water flow can enter the membrane, and the working pressure of the pipeline is reduced. When the water pressure in the pipe needs to be increased, the motor drives the piston to move downwards, so that the air pressure in the shell is increased, water in the membrane is extruded out of the membrane, and the water pressure in the pipe is increased. The water pressure in the pipe and the air pressure in the working cavity are balanced finally, namely the air pressure is large and the air pressure is small and the water pressure is small. Signal transmission path: the two Hall elements can sense the magnetic sheet attached to the membrane. The Hall element and the electric control board are combined, signals can be fed back to the motor after being processed, and the following movement is arranged. When the pressure of the chamber is insufficient and the height of the membrane is higher than a set maximum value (the Hall element cannot receive a magnetic signal when the pressure is high, but can receive the magnetic signal when the pressure is insufficient), the air pressure detected by the air pressure detection element 11 and the displacement detected by the Hall element are combined, the final result is fed back to an operator of the equipment and flickers, and a user is reminded that the expansion water tank is inflated at the moment.

The starting and stopping times of the dual-purpose furnace can be reduced, and the effects of protecting equipment and saving energy can be achieved.
