Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fracturing device, especially a fracturing device capable of preventing leakage. BACKGROUND

[0002] The fracturing device is a device for breaking, cracking rock or hard materials such as concrete in industry, which generates a transient pressure wave inside the target object by releasing high-pressure energy (such as gas expansion, liquid pressure or chemical reaction) to achieve safe breaking without blasting. Compared with traditional explosive blasting, the fracturing device has the characteristics of no open flame, low vibration, less splashing, environmental protection and controllability, and is widely used in fields such as mining, tunnel construction and building demolition. The gas expansion is usually a carbon dioxide fracturing device, which belongs to a mining physical fracturing device, and uses liquid carbon dioxide to be heated and gasified to expand and quickly release high-pressure gas to break rock or coal.

[0003] However, the existing carbon dioxide fracturing device usually uses a single threaded butt joint to seal, which has certain gaps inside, so it cannot ensure whether the cylinder will leak after the gas is injected, which affects the blasting effect. Therefore, we propose a fracturing device capable of preventing leakage to solve the above problems. SUMMARY

[0010] In further embodiments, the heating mechanism comprises a support, the outer surface of the support is connected with a heating rod, and the outer surface of the support is internally clamped with the limiting groove.

[0011] In further embodiments, the inner surface of the first internally threaded hole is externally threaded connected with the first externally threaded connecting pipe, the inner surface of the second internally threaded hole is provided with a third sealing ring, and the inner surface of the second internally threaded hole is provided with a burst sealing sheet.

[0012] Compared with the prior art, the device has the advantages that:

[0013] The first externally threaded connecting pipe is twisted in the inner surface of the first internally threaded hole, the first sealing ring is stressed and extruded, the contact area between the first externally threaded connecting pipe and the first internally threaded hole can be increased, the first sealing gasket is contacted with the inner surface of the first internally threaded hole after the first externally threaded connecting pipe is completely screwed in, the sealing performance after installation of the first externally threaded connecting pipe is ensured, according to the design of the one-way valve, the gas-liquid reverse leakage can be effectively avoided, the second externally threaded connecting pipe is twisted in the inner surface of the second internally threaded hole, and the second sealing ring is extruded, so that the sealing performance of the device after the gas is injected is ensured.
