Pressure-adjustable device for pressure vessel and implementation method of pressure-adjustable device

Abstract

The invention discloses a pressure-adjustable device for a pressure vessel, and further discloses an implementation method of the pressure-adjustable device for the pressure vessel. The pressure-adjustable device comprises a vessel bearing mechanism and a pressure adjusting mechanism, and one end of the vessel bearing mechanism is connected with the pressure adjusting mechanism. According to the device, the pressure in a tank body can be monitored in real time through a pressure measuring probe, a pressure numerical value is transmitted to a control box to be analyzed and processed, if it is judged that the pressure exceeds or is lower than a preset parameter, a first electromagnetic valve and a hydraulic oil cylinder are synchronously opened, and the hydraulic oil cylinder drives the cylinder rod to push an extrusion piston to move upwards or downwards; and therefore, the pressure at the bottom of the inner cavity of an upper pressure cylinder is reduced or increased, and air flow inthe tank body is conveyed into the upper pressure cylinder through a pressure pipeline to be subjected to pressure relief, or the air flow in the upper pressure cylinder is conveyed into the tank bodythrough the pressure pipeline to realize pressurization. Compared with a common pressure vessel, the pressure vessel has the advantage that the pressure value in the vessel can be conveniently adjusted by utilizing the motion state of the extrusion piston.

Description

technical field [0001] The invention relates to the technical field of pressure vessels, in particular to a pressure-adjustable device for a pressure vessel and an implementation method thereof. Background technique [0002] A pressure vessel is a closed container that can withstand pressure. The pressure vessel has a wide range of uses, and it has an important position and role in many sectors such as industry, civil, military, and many fields of scientific research. Among them, the most used ones are in the chemical industry and the petrochemical industry, and the pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. In the field of chemical industry and petrochemical industry, pressure vessels are mainly used for heat transfer, mass transfer, reaction and other processes, as well as storage and transportation of pressurized gas or liquefied gas; they are also widely used in other industrial and civil fiel...

AI Technical Summary

Problems solved by technology

[0003] Existing pressure vessels generally cannot adjust the pressure, and the pressure adjustment method is relatively simple, which cannot meet the needs of use. The pressure detection position is relatively fixed and the safety factor is low during use.
