Abstract

The utility model relates to a Y-branch like a two-head jet of a patching machine, which mainly comprises an inlet pulp pipe and two outlet pulp pipes connected into a Y-shaped integral body. The cross-section area of the inlet pulp pipe is greater than the sum of the cross-section areas of the two outlet pulp pipes. The inlet pulp pipe is communicated with the pipeline to the jet head by a coupler. The two outlet pulp pipes are respectively communicated with the flexible pipe to the jet head by a coupler. The utility model enables a patching machine to feed the operation of two jet heads. The inner diameter of the outlet pulp pipe is reduced, and thus the weight of the jet head flexible pipe is decreased. The utility model is convenient for one man operation. The reduced inner diameter of the flexible pipe accelerates the current velocity of the pulp, reduces dripping of the pulp, enhances work efficiency, reduces human power, and raises resource utilization.
