Abstract

A pressure-and-vacuum vent valve is a kind of important adjunct, which pressure testing relates to its security and reliability. According to the construction characteristic of pressure-and-vacuum vent valve in this paper, the pressure testing on all-weather QZF-89 pressure-and-vacuum vent valve is made. The calculation and analysis results indicate that the hydraulic pressure set as 0.9 MPa is reasonable for the valve body.
