Description
Technical Field
The utility model belongs to the technical field of tool parts, and particularly relates to a safety valve performance test clamp.
Background
The safety valve is one of common components of a hydraulic system of aviation equipment, and is mainly used for carrying out overpressure protection on important hydraulic products and avoiding damage to the products and airplane structures caused by overpressure of the system. The safety valve component needs to respectively test the opening pressure and the leakage amount under the double-hydraulic system in the performance test process, so that a measuring clamp which is simple and reliable in structure and convenient and quick to use needs to be designed.
SUMMERY OF THE UTILITY MODEL
The utility model provides a test fixture which is simple and reliable in structure and convenient and quick to use, so that the opening pressure and the leakage amount of a safety valve under two hydraulic systems can be measured.
The technical scheme of the utility model is as follows: a safety valve performance test fixture comprises a shell, a left plug, a right plug and a sealing ring; the shell is of a cavity structure, the upper end of the shell is provided with an oil inlet A and an oil inlet B, and the lower end of the shell is provided with an oil return port R; the oil inlet A and the oil inlet B are connected with an external hydraulic source through quick connectors; and a left plug and a right plug are respectively arranged at two ends of the shell, and a sealing ring is arranged.
Furthermore, threads are arranged on the left plug and the right plug and are fixed at two ends of the shell through the threads.
And the left/right plug and the sealing ring are used for compressing and sealing the safety valve. The pressure of the oil inlet A or the oil inlet B is adjusted as required, so that the opening pressure and the leakage quantity can be measured, and the performance test of the safety valve under two hydraulic systems can be respectively completed through one-time switching.
The utility model has the beneficial effects that: the clamp is simple and reliable in structure, the oil inlet A or the oil inlet B is connected with a hydraulic source through the quick connector, the opening pressure and leakage quantity of the safety valve under two hydraulic systems can be measured by switching the quick connector once, the switching mode is simple, and the test efficiency of the safety valve can be effectively improved.
