One end of the first spring 406 abuts against the piston 404, and the other end of the first spring 406 abuts against the control box 401. Under the action of the first spring 406, the piston 404 is driven to move right, so that the return oil pipe 403 remains in a closed state.

[0035] Specifically, the working process or working principle of the constant pressure device for a heat-conducting oil furnace is as follows: when in use, heat-conducting oil is added to the compensation tank 2 through the oil inlet pipe 3. When the pressure in the heat-conducting oil furnace 1 is too low, under the action of the first spring 406, the piston 404 is driven to move right, so that the return oil pipe 403 remains in a closed state. Under the action of the second spring 411, the baffle 408 is driven to move downward, so that the oil replenishment pipe 402 remains in a conducting state. The heat-conducting oil in the compensation tank 2 can enter the oil furnace 1 through the oil replenishment pipe 402 to achieve oil replenishment. When the pressure in the heat-conducting oil furnace 1 is too low, the piston 404 is driven to move right, so that the return oil pipe 403 remains in a closed state. Under the action of the second spring 411, the baffle 408 is driven to move downward, so that the oil replenishment pipe 402 remains in a conducting state. The heat-conducting oil in the compensation tank 2 can enter the oil furnace 1 through the oil replenishment pipe 402 to achieve oil replenishment. When the pressure is high, the piston 404 is driven to move left, the first spring 406 contracts, driving the first connecting rod 405 and the first wedge block 407 to move left synchronously, driving the second wedge block 414 to drive the third connecting rod 413 to move upward, driving the baffle 408 to gradually block the oil replenishment pipe 402, and stop replenishing oil. If the pressure continues to rise, the piston 404 is driven to move left until the return oil pipe 403 is opened, and the heat transfer oil in the heating oil furnace 1 flows back to the compensation tank 2 through the return oil pipe 403, thereby realizing the pressure relief of the heat transfer oil furnace 1, maintaining the pressure in the furnace stable, and eliminating safety hazards.
