Abstract:
In order to realize the field dynamic calibration of water hammer pressure sensor and simulate the state of liquid water hammer pressure, a set of quick-closing valve used in the field calibration of water hammer pressure sensor was developed, and the material of brittle sheet as a key valve part was selected and verified. The test results show that the close time of quick-closing valve meets the design requirements, and the practical effect is good, which can provide an important basis for the dynamic calibration of dynamic water hammer pressure.
