Abstract

The invention discloses a twisting resistance detection system for a gas filling hose and particularly relates to the technical field of twisting resistance detection of hoses. The twisting resistance detection system overcomes the defect that an existing gas filling hose detecting device can only detect the anti-tensile property of gas filling hoses. The twisting resistance detection system for the gas filling hose comprises a gas source generating device, a pressure regulating device, a twisting resistance detecting device and a monitoring device. The output end of the gas source generating device is connected with the pressure regulating device. The twisting resistance detecting device is used for being connected with the pressure regulating device. The gas source generating device comprises a compressor which is connected with a gas storage container. The output end of the gas storage container is connected with a cut-off valve. The pressure regulating device comprises a pressure stabilizing valve which comprises a plurality of stages of branch circuits. The outlets of the branch circuits are each provided with a valve. The twisting resistance detecting device comprises a detecting port and a fixing table. A clamping sleeve is arranged on the detecting port. A camera is arranged in the twisting resistance detecting device and connected with the monitoring device.

Description

technical field [0001] The invention relates to the technical field of detecting the kink resistance of hoses, in particular to a detection system for the kink resistance of gas filling hoses. Background technique [0002] In 2013, my country's natural gas imports increased by 25% year-on-year to 53 billion cubic meters, and the annual apparent consumption of natural gas reached 167.6 billion cubic meters. Natural gas has become one of the main energy sources in my country. Natural gas mainly exists in the form of compressed natural gas (CNG). As the consumption of CNG increases year by year, the number of CNG filling stations also increases year by year. The CNG filling station terminal gas filling machine delivers CNG to the car cylinder through the gas filling hose for the car to use. Since the pressure of CNG transported by the gas filling hose is as high as 20MPa, the requirements for compressive tensile strength and kink resistance of the gas filling hose are very hig...
