The present invention relates to a serviceability test bed of an 80 percent limit filling device, which is used for an 80 percent limit filling and loading serviceability test of an LPG (liquefied petroleum gas) gas cylinder integrating valve for a vehicle, and according to a dedicated test bed which is designed according to requirements and regulations in GB18299 Liquefied Petroleum Gas Steel Cylinder Integrating Valve for a Motor Vehicle, the test bed consists of an electrical control part and a water pressure part, the electrical part comprises a control system and a computer display system, and the water pressure part mainly consists of a gas drive liquid pump, an energy accumulator, a pressure reducing valve, a centrifugal water-pump and the like. The combination of the energy accumulator and the pressure reducing valve can precisely control the pressure difference of two ends of a valve to be tested, and the test bed has the characteristic of stable pressure, thus guaranteeing the test pressure to meet the demands of GB18299 standards completely.
Description
technical field [0001] The invention relates to the field of durability tests for integrated valves, in particular to a durability test bench for an 80% filling limiting device for integrated valves of liquefied petroleum gas cylinders for LPG vehicles. Background technique [0002] The integrated valve of the liquefied petroleum gas cylinder for motor vehicles is an important part of the liquefied petroleum gas cylinder for motor vehicles, and this part works when the motor vehicle is running. In order to achieve normalization and standardization and ensure quality and safety, the standard "GB18299 LPG Cylinder Integrated Valve for Motor Vehicles" has been formulated. Whether users, valve manufacturers or testing organizations want to understand and master the reliability of valve quality in a short period of time, they must rely on valve life test devices. However, there is no ideal device for testing them. Contents of the invention [0003] The technical problem to be ...
