摘要（英）：

The utility model provides a remote pressure display system for a cable blowout preventing device, and belongs to the field of wellhead sealing and blowout preventing of oil and gas exploration and development. The remote pressure display system comprises a pressure-transmitting four-way joint, a first stop valve, a second stop valve, a pressure sensor and a shock-proof pressure gage. The shock-proof pressure gage is connected with the upper port of the pressure-transmitting four-way joint. One end of the pressure sensor is connected with the lower port of the pressure-transmitting four-way joint, and the other end of the pressure sensor is connected with a wellhead pressure digital display gage of a hydraulic control grease injecting system. The left port and the right port of the pressure-transmitting four-way joint are respectively connected with a pressure release pipe. The other end of the pressure release pipe connected with the left port is connected with a fast connector female end, and the other end of the fast connector female end is connected with the first stop valve. The other end of the pressure release pipe connected with the right port is connected with the second stop valve.
