Abstract

The invention discloses a pressure device comprises a pressure device, a cover board, an over-pressure outage switch and a trigger device; the cover board is installed on the pressure device; a pressure space is defined between the cover board and the pressure device; a penetrating through hole is formed in the cover board; the over-pressure outage switch is installed on the cover board and is positioned at the through hole; the trigger device is installed between the cover board and the over-pressure outage switch; the trigger device comprises a push rod and an elastic sealing member; the push rod is movably installed between the cover board and the over-pressure outage switch; a first end of the push rod is adapted to trigger the over-pressure outage switch so that the over-pressure outage switch is cut off; the elastic sealing member is installed at the through hole; the elastic sealing member is connected with a second end of the push rod; when the pressure in the pressure space reaches a preset pressure, the pressure in the pressure space is directly applied on the elastic sealing member to drive the push rod to move to trigger the over-pressure outage switch so that the over-pressure outage switch is cut off and the pressure device is powered off. According to the pressure device of the invention, the use safety of the pressure device is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of pressure equipment, in particular to a pressure appliance. Background technique [0002] In the related art, there are usually the following two modes to protect pressure vessels such as electric pressure cookers or electric pressure cookers: 1. Directly discharge pressure medium gas or liquid to release pressure. However, this mode does not cut off the power supply, and the pressure medium discharge channel is easy to be blocked, and the device is easy to fail. 2. Temperature over-temperature and over-pressure protection: The temperature sensor senses the temperature in the container, and the working power is cut off through the mechanical temperature controller or the electric control program, so that the pressure container stops working and the pressure is reduced. However, this mode requires the conversion of pressure and temperature, the control accuracy is not high, and the safety performance is low. During...
