Abstract

The invention discloses a non-return valve assembly and a pumping-filling pipeline system provided with the non-return valve assembly. According to the non-return valve assembly and the pumping-filling pipeline system, impact of filling slurry on an S-valve-type piston-type filling industrial pump can be avoided. The non-return valve assembly comprises a valve body and a first electromagnetic reversing valve set. The valve body comprises a shell, a valve element and valve body oil cylinders. A feeding inlet in the shell is matched with an outlet of the S-valve-type piston-type filling industrial pump in the pumping-filling pipeline system. When the valve body oil cylinders drive the valve element to move to the limiting position in the shell, the shell is closed, and when the valve body oil cylinders drive the valve element to leave the limiting position, the shell communicates; the first electromagnetic reversing valve set is used for controlling the valve body oil cylinders; and an Spipe in the S-valve-type piston-type filling industrial pump is driven by a swinging oil cylinder to swing, the swinging oil cylinder is controlled by a second electromagnetic reversing valve set, and the first electromagnetic reversing valve set and the second electromagnetic reversing valve set are connected in parallel and makes action synchronously.

Description

technical field [0001] The invention relates to the technical field of mine paste filling, in particular to a check valve assembly and a pumping filling pipeline system provided with the check valve assembly. Background technique [0002] Paste filling is to make mine tailings, gravel, fly ash, industrial slag and other solid waste into a paste-like slurry that does not need to be dehydrated, and transport it to the underground filling area through pipelines through pump pressure or gravity. In the paste filling system, according to the filling process, it can generally be divided into 5 subsystems, namely tailings slurry thickening system, aggregate crushing and screening system, filling slurry mixing preparation system, pumping filling pipeline system, electrical control system etc. [0003] In the paste filling system, some filling stations are built below the filling roadway, and the filling pipeline must be arranged upward along the slope. In this way, the filling slu...
