| description | The invention discloses a carbon dioxide fracturing device and a filling method. The carbon dioxide fracturing device comprises a filling valve, a heating device, a liquid storage pipe, a sealing pad, a fixed-pressure shearing piece and a release pipe. The filling valve is provided with a valve body and a breakover portion located in the valve body. The breakover portion is used for inputting power to the other end of the filing valve from one end of the filling valve. The valve body is provided with an input opening for inputting liquid carbon dioxide, an output opening for outputting liquid carbon dioxide and a stop valve. A passageway is formed between the input opening and the output opening. The stop valve is used for controlling connection and disconnection of the passageway. One end of the stop valve is located on the outer surface of the valve body and the other end of the stop valve is located on the passageway. The filling valve is easy and convenient to operate, the filling method adopting the fill |
