Problems solved by technology

[0002] As a kind of pressure-bearing equipment, the pressure chamber is widely used in the field of petrochemical industry. In recent years, it has been greatly developed in the field of oil and gas exploration and displacement experiments; The body is fixed together, because the working pressure of the pressure chamber is high, the load carried by the main bolt is relatively large, resulting in large bolt specifications and large pre-tightening force, and it is very difficult to close and open the pressure chamber; in terms of oil and gas exploration and displacement experiments, due to Experiments are frequent. After each experiment is over, the pressure chamber must be opened for analysis. When doing a new experiment, the pressure chamber must be closed again, which has brought great labor intensity to the vast number of scientific researchers. At the same time, Greatly increased the preparation period of the experiment and reduced the efficiency of the experiment
