Description

Particle mixing injection valve assembly Technical Field The invention relates to the technical field of liquid injection valve bodies, in particular to an injection valve assembly for circulating mixed particles in a liquid injection process. Background Particles are mixed in the liquid jet flow, so that the scouring effect of the liquid pair can be improved, and the liquid jet flow can be applied to the industrial fields such as high-pressure water jet cutting and low-pressure cleaning of dirt on the inner wall of a workpiece. The particles mixed into the jet flow are in a continuous recycling state, the shorter the recycling path of the particles is, the higher the utilization rate of the particles is, the smaller the consumption is, and the smaller the storage space occupied by the particles is. At the end of the cleaning of the workpiece, particles remain on the inner wall of the workpiece, which requires flushing and cleaning again, and this operation requires cutting off the mixed jet of particles and liquid, and then switching to a jet flush without particles, or transferring to a separate cleaning tank for immersion cleaning, but transferring cleaning consumes particles, which requires continuous replenishment of particles to maintain the stability of the circulating density. Therefore, the injection valve device integrating the functions of particle mixing, circulation and on-off conversion is designed, so that the jet flow conversion efficiency can be improved, and the particle consumption can be prevented.
