Product introduction:




The swing check valve adopts the built-in rocker swing structure. All the opening and closing parts of the valve are installed inside the valve body and do not penetrate the valve body. Except for the sealing gasket and sealing ring used at the middle flange, there are no external leakage points as a whole, so as to eliminate the possibility of valve leakage. The connection of swing check valve rocker arm and valve disc adopts spherical connection structure, so that the valve disc has a certain degree of freedom within 360 degrees and has appropriate micro position compensation. It is suitable for clean media, not for media containing solid particles and high viscosity. It can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium, urea and other media. It is mainly used in petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other pipelines.






Product features:




The valve is composed of valve body, valve cover, valve disc, rocker and rocker shaft. The valve disc can automatically prevent fluid backflow. The valve disc of the valve is opened under the action of fluid, and the fluid flows from the inlet side to the outlet side. When the inlet pressure is lower than the outlet pressure, the valve disc will automatically close under the action of fluid pressure difference, its own gravity and other factors to prevent backflow.
