Problems solved by technology

However, ordinary wrenches can easily cause unbalanced force on the high-temperature autoclave body during use, thereby destroying the threads of the autoclave, causing the autoclave body to lock and cannot be opened.
On the other hand, when using an ordinary wrench to seal the high-temperature autoclave, because it is impossible to determine how much torque is required to achieve the sealing of the autoclave, that is, it is impossible to quantitatively provide a large torque to seal the autoclave so that it does not leak, which often leads to the sealing of the autoclave. Due to poor performance and air leakage under high temperature and high pressure conditions, the experiment failed, and also greatly reduced the certainty and reproducibility of the experiment

Embodiment Construction

[0017] figure 1 It is a structural diagram of a hollow hydraulic wrench. As shown in the figure, the hollow hydraulic wrench includes a hollow sleeve (1) and a hydraulic wrench main body (2). The hydraulic wrench main body (2) can be connected to a manual high-pressure oil pump through a hydraulic oil pipe.

[0018] figure 2 It is a schematic diagram of a hollow hydraulic wrench working platform, including a limiting column (3), a clamping hole (4) and a supporting leg (5). The limiting column (3) is fixed on the working platform through a card slot (6), and the supporting leg ( 5) Connect with the platform through the relevant design on the bottom of the platform:

[0019] A1: Place the autoclave in the hole (4) fixed on the working platform of the hollow hydraulic wrench;

[0020] A2: Put the hollow hydraulic wrench hollow sleeve (1) into the autoclave lid (11), wherein, when opening the autoclave, the hydraulic wrench hollow sleeve (1) needs to be inserted into the lid (...

Abstract

The invention relates to a high pressure kettle switching device system and method, and belongs to the field of hydrothermal / solvothermal high-temperature and high-pressure devices used for laboratories. The high pressure kettle switching device system comprises a hollow hydraulic wrench, a hydraulic wrench workbench and a manual high pressure oil pump, a sleeve of the hollow hydraulic wrench is directly nested in an high pressure kettle cover (11), and a high pressure kettle is fixedly placed in block holes (4) of the hydraulic wrench workbench. The system and the method realize sealing or opening of the high pressure kettle through a quantified controllable super-large twist moment, so the screw thread of the high pressure kettle is well protected, and the sealing and opening operations of the high pressure kettle are quantified, thereby the reappearance, the efficiency and the success rate of hydrothermal / solvothermal high-temperature and high-pressure kettle are greatly improved.

Description

technical field [0001] The invention belongs to the field of high-temperature and high-pressure equipment for laboratories, and in particular relates to a switch device system and method for a simple high-temperature and high-pressure kettle. Background technique [0002] High-temperature autoclave is a hydrothermal / solvothermal reaction vessel. Under the action of external heating equipment, the temperature of the working medium in the autoclave can reach 300-600 ° C, and an atmospheric pressure of 1-300 MPa can be generated in the autoclave. Under these extreme conditions, some chemical reactions that cannot occur under normal temperature and pressure can be better realized in supercritical solvents in high-temperature and high-pressure autoclaves, thereby realizing the synthesis and preparation of novel and unusual materials, especially the synthesis of nanomaterials preparation. However, under the extreme conditions of high temperature and high pressure, how to realize ...
