Description

Technical Field

[0001] This utility model relates to the field of rock fracture material production technology, specifically to an injection-type directional gas energy expansion rock fracture material production device. Background Technology

[0002] In the production of rock-fractured materials, an injection-type directional gas-energy expansion rock-fractured material production device is required. This device is used to produce materials that can achieve directional rock fracturing through gas expansion. Currently, the most common device is based on the principle of carbon dioxide phase change, which utilizes the characteristics of carbon dioxide phase change, where liquid carbon dioxide absorbs heat and expands instantaneously.

[0003] The existing injection-type directional gas-energy expansion rock-fracture material production equipment still has the following problems when in use: its working temperature range is limited, that is, the working effect of the equipment is greatly affected by temperature. In low temperature environment, the vaporization rate of liquid carbon dioxide may slow down, resulting in a slow rise in expansion pressure and affecting the rock-fracture effect. In high temperature environment, the pressure inside the equipment may be too high, increasing safety risks and even causing equipment failure or damage. Utility Model Content
