Abstract

The invention discloses a carbon dioxide filling valve and a fracturing device. The filling valve is provided with a valve body and a communication part located in the valve body. The communication part comprises a first electrode and a second electrode. The valve body is provided with a liquid carbon dioxide input port, an output port and a stop valve. Both the first electrode and the second electrode are insulated from the valve body and coupled. The stop valve is used for opening and closing a passage between the input port and the output port. The filling valve is characterized in that the communication part further comprises a third electrode and a fourth electrode which are insulated from the valve body and coupled, the first electrode and the third electrode are insulated from each other, the second electrode and the fourth electrode are insulated from each other, and the communication part is made of a conductor material with the tensile strength over 200 MPa. The filling valve and the fracturing device with the filling valve have the quite reliable electricity conducting performance and the quite high anti-pressure capacity.

Description

technical field [0001] The invention belongs to the field of blasting devices, in particular to a carbon dioxide filling valve and a cracker. Background technique [0002] In the mining of mineral resources, explosive blasting is one of the commonly used methods at present. Explosive blasting is a typical open flame blasting, which has the advantages of high power and strong effect. However, open flame blasting has obvious defects, and it has very high requirements for use conditions, working environment and operation management, especially in underground coal mines, where many coal mine gas accidents are caused by open flames. At the same time, other accidents caused by explosive blasting also occur from time to time, which have serious consequences for the safe production and operation of enterprises. [0003] Aiming at the above-mentioned problems of explosive blasting, a high-pressure gas blasting technology using carbon dioxide cracking has emerged in the industry. T...
