Embodiment Construction
[0018] Coal seam gas dynamic action simulation system includes gas injection system, sample loading system, compaction system and information collection system. The sample loading system includes a cylinder body 1, which is made of corrosion-resistant and high-pressure-resistant materials. In order to reduce the processing difficulty and improve the manufacturability, the cylinder body 1 is designed to be divided into two sections, and the inner wall is roughened to prevent cross-flow. Install the discharge end cover 2, there is a discharge port on the discharge end cover 2, the quick-opening air relief valve 3 is installed on the discharge end cover, and the other section is equipped with a hydraulic plunger 4, a hydraulic cylinder end cover 5, a hydraulic plunger 4, a hydraulic There is a sealing mechanism between the cylinder end covers 5, and a sealing adjustment mechanism is arranged outside the hydraulic cylinder end cover 5, so that the seal can be guaranteed by pressing...
