Embodiment 1
[0020] Example 1 The entrance of the lower end of the mine drainage system is a drainage pump, and then a pig launching chamber, a non-resistance check valve and a drainage pipeline are installed in sequence, as shown in the figure, the non-resistance check valve is a valve housing connected to the pipeline 1. The valve plate 3 is composed of the valve seat 4 set on the valve casing. The one-way opening valve plate is hinged on the valve seat. When the valve plate is closed, the lower end surface of the valve plate matches the valve seat. The maximum opening degree of the valve plate is 90°, the upper end surface of the valve plate is provided with a spring 5 perpendicular to the valve plate surface, the spring ensures that the valve plate returns to 70° when the opening angle reaches 90°, and an elastic spring is set on the lower end surface of the valve plate of the non-resistance check valve. Nylon protective layer2. First, use a pig to remove and clean the possible foreign...
