Abstract

The invention discloses a check valve assembly and a pumping filling pipeline system provided with the check valve assembly, which can prevent the impact of the filling slurry on the S-valve type piston filling industrial pump. The check valve assembly includes a valve body and a first electromagnetic reversing valve group. The valve body includes a shell, a valve core and a valve body cylinder. The feed port on the shell is adapted to the outlet of the S-valve piston filling industrial pump in the pumping and filling pipeline system, and the valve body cylinder drives the valve core to move in the shell. When reaching the limit position, the shell is closed, and the valve body cylinder drives the spool to leave the limit position, and the shell is connected; the first electromagnetic reversing valve group is used to control the valve body cylinder; the S pipe in the S valve type piston filling industrial pump is oscillated The oil cylinder drives the swing, and the swing oil cylinder is controlled by the second electromagnetic reversing valve group, and the first electromagnetic reversing valve group and the second electromagnetic reversing valve group are arranged in parallel and act 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...
