Description

Technical Field

[0001] The utility model relates to the technical field of experimental auxiliary equipment, in particular to an operating fixing tool for a small-sized simple high-pressure reactor. Background Art

[0002] The high-pressure reactor (magnetic high-pressure reactor) is a typical innovation of the application of magnetic transmission devices to reaction equipment. It fundamentally solves the shaft seal leakage problem that could not be overcome by previous packing seals and mechanical seals. It has no leakage and pollution and is the most ideal device for chemical reactions under high temperature and high pressure in China. It is particularly superior for chemical reactions with flammable, explosive and toxic media.

[0003] High-pressure reactors are precision equipment. They are sealed by using a sealing ring with conical surfaces in contact. By tightening the main bolts, they are pressed against each other to achieve the purpose of sealing. Special care must be taken for the sealing cone to avoid damage caused by various collisions. When installing the cover, first place the reactor body, then carefully install the reactor cover on the reactor body in a fixed position. When tightening the main bolts, they must be tightened diagonally and symmetrically in multiple steps. The force must be even, and the reactor cover is not allowed to tilt to one side to achieve a good sealing effect. The specified tightening torque must not be exceeded to prevent the sealing surface from being squeezed or accelerated wear.

[0004] Each time a small high-pressure reactor is bolted, two people are required to assist. One person holds the two operating handles of the high-pressure reactor with both hands to fix it so that it does not shake, and the other person tightens the bolts with a wrench. The operation is troublesome and laborious. It is necessary to develop an operating and fixing device for a small and simple high-pressure reactor. Utility Model Content
