Problems solved by technology

This explosion-proof device has the effect of automatic pressure relief, but still has the following disadvantages: 1. The preparation process of the explosion-proof sheet is complicated, and the manufacturing cost is high. The explosion-proof sheet used for a reaction kettle above 1 cubic meter usually costs more than 1,000 yuan
2. The explosion-proof pressure of the explosion-proof disk is determined by the manufacturer and cannot be changed by the user, and the selection of the explosion-proof disk is very strict. Generally, it needs to be selected according to the pressure requirements of the reactor according to the production process regulations. For example, the b

Abstract

The inventive device comprises an outer cylinder, a magnetic flowing liquid in the cylinder, a diaphragm, a magnet coil wound on the cylinder, top and bottom joints, a current driver, a controller and a pressure sensor. The diaphragm is above the bottom joint. The joint of the magnet coil is connected with the power supply of the current driver and the current driver is connected with the controller. The bottom joint is connected with a vessel and the top joint is connected with an emptying pipe. The pressure sensor is mounted in the vessel for testing the pressure in the vessel and sending the pressure signal into the controller. According to the contrast signal of the tested pressure with the design pressure-limiting value, the controller is used for controlling the power supply and the power-off of the magnet coil.

Description

technical field [0001] The invention relates to an intelligent adjustable container overvoltage protection device and method based on magnetorheological fluid, more precisely, relates to an intelligent adjustable container overvoltage protection device and method using magnetorheological technology. Background technique [0002] Containers usually have protective devices to prevent the explosion of the container itself due to excessive internal pressure, especially pressure vessels. The most common example is the pressure reactor in chemical production. At present, the measures taken are to install vent valves and explosion-proof devices on the pressure reactor. The vent valve is used to manually control the pressure in the reactor. When the pressure in the reactor exceeds the process specification When a certain limit value is reached, the operator manually opens the vent valve to reduce the pressure in the reactor to within the range required by the process regulations, an...
