Anti-explosion safety device of autoclave

Abstract

The invention discloses an anti-explosion safety device of an autoclave. A through hole is arranged on a cover of the autoclave, a hollow cylinder is sealed and fixed on the through hole communicated with the hollow part of the hollow cylinder, the hollow cylinder is provided with a circular upper end, radial threads are arranged on the outer cylindrical surface of the upper end, and a fusible sheet covers the hollow part of the upper end of the hollow cylinder and is smaller than the upper end of the hollow cylinder; the upper part of the inner wall of a nut is provided with a baffle plate which faces to a geometric center shaft of the nut screwed with the upper end of the hollow cylinder, the baffle plate seals and compresses the fusible sheet, and the middle of the fusible sheet is exposed; the fusible sheet can be fused under the function of high-pressure steam to provide an exhaust passage for high-pressure air, and the diameter of the exhaust passage is 1 centimeter so that the exhaust passage can not be blocked by stewed foods, thereby the fusible sheet takes the effect of absolute explosion prevention; and after the fusible sheet is fused, the fusible sheet needs to be replaced by a new fusible sheet. Compared with the traditional anti-explosion safety device of the autoclave, the anti-explosion safety device of the autoclave in the invention is safer and more efficient and has simple structure and low cost, and is easy to implement.

Description

technical field [0001] The invention relates to a device for preventing explosion of a pressure cooker. Background technique [0002] The current pressure cooker explosion-proof device consists of three valves: a pressure reducing valve, a safety valve and a spare safety valve. Pressure relief; when the pressure relief valve is blocked, the safety valve will play the role of pressure relief and explosion protection. However, due to the small stress area of ​​the safety valve, the effect is not absolute, and there will be pressure cooker explosion accidents in the society; and because the food will be boiled at high temperature, it will overflow along the pressure reducing valve under high pressure, and it will take a long time. Otherwise, the safety valve and pressure reducing valve may be blocked. Because of the explosion-proof defect existing in the current pressure cooker, many people feel unsafe, especially the people who use it for the first time. Contents of the in...
