The axial check valve is a new product after the introduction of the new standard in 2008. The working principle of the axial flow check valve is as follows: the pressure difference between the inlet end and the outlet end of the valve determines the opening and closing of the valve flap when the pressure at the inlet end is large and the outlet When the pressure cycle of the end expands the sum of the spring forces, the flap opens. As long as there is a pressure difference, the valve flap is always open, but the degree of opening is determined by the magnitude of the pressure difference. When the sum of the outlet end pressure and the spring force is greater than the inlet end pressure difference, the flap is closed and remains closed. Since the opening and closing of the valve flap is in a dynamic force balance system, the valve is balanced, no noise, and the water hammer phenomenon is greatly reduced.
In addition to the function of the general check valve, the axial flow check valve is also designed with a shock absorbing spring. The combined sealing seat structure of the hard seal with soft seal has anti-sound and shock absorption effect, which is convenient for on-site inspection. At the same time, because the axial check valve adopts a special sealing structure, regardless of the pressure behind the valve, the valve is closed tightly and the sealing performance is good, which overcomes the shortcomings of the general check valve with poor sealing performance at low back pressure.
