Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

A gas overflow protection device suitable for a condenser is arranged between a material cavity and a condensation cavity in a condenser cavity, and is composed of a first separation cavity and a second separation cavity, wherein the first separation cavity is adjacent to the material cavity, the second separation cavity is adjacent to the condensation cavity, and the volume of the first separation cavity is smaller than that of the second separation cavity.

The top of the first separation chamber is provided with a first gas overflow port, and the top of the second separation chamber is provided with a second gas overflow port; the valve body is arranged at a first gas overflow port, the bottom of the valve body is open, the valve body is communicated with a first separation cavity through the first gas overflow port, a piston connected with a spring top is arranged in the valve body, a first exhaust port, a second exhaust port and a third exhaust port are arranged on the side wall of the valve body along the compression process of the spring, the second exhaust port is connected with the second gas overflow port through a gas overflow pipe, the first exhaust port and the third exhaust port are respectively connected with an absorption tank filled with material absorption liquid, and the first exhaust port and the third exhaust port are respectively provided with a gas pressure alarm device.
