Abstract

The invention relates to an LPC globe valve durability test bench which is used for LPG vehicle liquefied petroleum gas cylinder check valve durability testing and detection, is applicable to a manual check valve and an electromagnetic valve, and mainly comprises two parts, i.e. a durability testing device and a control system. The highest use pressure of the test bench is 1MPa compressed air, and the test bench automatically records the relation between pressure and circulation times through a durability test control unit and a pressure sensor, automatically draws a corresponding output pressure and time curve according to a preset pressure-time relation characteristic curve, has good sealing performance, is provided with an exhaust function, and can exhaust the air in a tester and a tested valve.

Description

technical field [0001] The invention relates to the field of durability testing of cut-off valves, in particular to a durability test bench for LPG cut-off valves. 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 standardization and standardization, and ensure quality and safety, the standard "GB18299 Integrated Valve for Liquefied Petroleum Gas Cylinders for Motor Vehicles" was formulated, which also stipulates the standards for shut-off valves for LPG cylinders for vehicles. 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 tec...
