Furthermore, a piston is arranged in the heat reservoir, and a cylinder is arranged above the piston.

Furthermore, the heat storage pipe and the heat release pipe are both provided with electromagnetic valves.

Further, the inner tube bottom has the through-hole and communicates with communicating pipe, dispose temperature sensor in communicating pipe, and communicating pipe is equipped with electric valve.

Furthermore, the heat storage pipe is also provided with a pressure gauge.

The utility model has the advantages that: through barrel bottom heating, make steam up through hollow connecting rod and inner cup evenly get into the inner tube in, can make the product on the supporter reach the effect of synchronous intensification, after reaching preset pressure and temperature, can reserve the storage to steam automatically to preheat the start once more, can reduce the energy consumption when equipment uses in succession, raise the efficiency.

Description of the drawings:

fig. 1 is a schematic structural diagram of the box body of the present invention.

The specific implementation mode is as follows:

please refer to fig. 1, which is a schematic structural diagram of a preferred embodiment of the present invention, the present invention relates to a pressure steam sterilization device, which mainly comprises a barrel 1 and a cover, wherein the barrel 1 is provided with an inner tube 3, the bottom of the barrel 1 is recessed, and the recessed portion is provided with a communicating tube 4 connected to the barrel 1 and the inner tube 3, a waterproof sealing ring should be provided between the communicating tube 4 and the barrel 1, the bottom of the inner tube 3 is provided with a through hole communicated with the communicating tube 4, in fact, the inner tube 3 is supported by the communicating tube 4, and the air in the inner tube 3 and the water in the later stage can be discharged from the communicating tube 4.

The protruding annular part in barrel 1 bottom is provided with heating device 5 and drain pipe 6, and heating device 5 is the heating tube and is the annular, heats the water of barrel 1 bottom, makes it form during vapor rises and gets into inner tube 3, and vapor gets into inner tube 3 from barrel 1 when, can discharge the air from inner tube 3 bottom to communicating pipe 4 gradually.

The cover body comprises an inner cover 21 and an outer cover 22, the outer cover 22 is matched with the cylinder body 1, a sealing ring is arranged between the inner cover and the outer cover 22 to enable the cylinder body 1 to form a sealing state, and a safety valve 23 is arranged above the outer cover 22. The inner cover 21 is fit with the inner cylinder 3, a sealing ring is arranged between the inner cover and the inner cylinder 3 to relatively separate the cylinder 1 from the inner cylinder 3, a plurality of through holes are uniformly distributed on the inner cover 21, and steam can only enter the inner cylinder 3 through the through holes on the inner cover 21.
