Abstract

A still kettle door-opening safety interlocking structure includes a pressure release valve (1), a door lock mechanism and an interlocking mechanism. The pressure release valve (1) is installed on theouter side of a kettle body (41) of a still kettle, the interlocking mechanism includes a linkage rod (31), a handle (32), a travel switch (33) and a kettle door dragging mechanism. The linkage rod (31) is movably mounted on a lock catch (21) or the kettle body (41) through a linkage rod frame (311), one end of the linkage rod (31) is connected with the pressure release valve (1), the other end of the linkage rod (31) is connected with the handle (32), the travel switch (33) is mounted on the lock catch (21) or the kettle body (41), and the linkage rod (31) is further connected with the travel switch (33) through a cam (36). The linkage rod (31) is connected with the door lock mechanism through the kettle door dragging mechanism. The pressure release on a still kettle and the opening of akettle door can be performed consistently, the still kettle door-opening safety interlocking structure is convenient and quick, and the still kettle door-opening safety interlocking structure can avoid accidents caused by misoperation.

Description

technical field [0001] The invention relates to a door opening device for a closed pressure tank, in particular to a safety interlock structure for opening the door of an autoclave. Background technique [0002] An autoclave (such as a steamer used in large restaurants, canteens, and hotels) is a sealed pressure pot. When the door (or lid) is opened, it is very uncomfortable to open the door directly because of the high-temperature and pressurized steam inside. For safety, at present, the pressure is usually released by opening the valve switch first, and then the door is opened. This technology will have the following problems: [0003] 1. Separate operations successively, with many operation steps, labor-intensive and time-consuming; [0004] 2. The operator must first remember to open the pressure relief valve before opening the door. Once he forgets to open the pressure relief valve first and opens the kettle door, a major safety accident may occur. Contents of the in...
