The check valve 3 is used for preventing the reverse flow of oil flow in a hydraulic system or compressed air in a pneumatic system, so that the medium can only flow along an inlet, but the medium cannot flow back out of an outlet. The non-return valve 3 can be mounted on the pipeline by means of a threaded connection.
The liquid storage tank is additionally arranged in the middle of the gas transmission pipe, when the dust suppression liquid is in a small amount of countercurrent, the dust suppression liquid can be stored in the liquid storage tank and cannot directly flow backward into the gas storage tank of the gas pump. Along with the increase of the service time, the accumulated liquid is more and more, when the upper edge of the liquid is higher than the lower edge of the gas pipe, the redundant dust suppression liquid can be input into the main liquid supply pipe through the gas pipe when the pipeline is cleaned, so that the liquid level of the liquid is always kept at the lower edge of the gas pipe.
