On the valve body and the fuel oil tankers of suction pipe, when the fuel tankers motor starting, form a negative pressure suction tube, make the body side pressure is higher than on the body side pressure;The disc under the influence of the fluctuation pressure difference is raised up, the oil which can enter the tankers suction tube, after the machine stop working, the valve body cavity pressure disappears, and due to the static pressure oil into positive pressure, the disc closed automatically under the effect of positive pressure, the oil from falling.Because the check valve with two sets of the same body and disc, make the performance of the check valve is more reliable.
