摘要

Summary "valve type dart or stopper for opening, closing or modulation of the abrasive fluid flow, such as pulp or tailings of ore, and the plug is shaped like an inverted pyramid of polygonal base and the seat has a polygonal perimeter, which fits with the surface exter In one ", because it is the present invention of a valve type dart or stopper for opening.Closing or modulation of the abrasive fluid flow, such as pulp or mineral tailings, for systems that operate under atmospheric pressure or pressurized systems, which prevents turbulence and vibration, which comprises a plug (1) kingdom, in the upper portion, a rod (2), Sen. He all involved by a valve body (4),With the valve body (4) is connected to an inlet tube (5) and an outlet pipe (6); and in the connection between the outlet pipe (6) and the valve body (4) is located in a seat (3); and the said plug (1) has the shape of an inverted pyramid base polig The United States Agency for international and its seat (3) has a polygonal perimeter, which fits with the external surface of the plug.The present invention also refers to a valve type dart to be used in abrasive fluids containing large particles, such as, for example, stones, which impede the proper modulation of the fluid. 1 / 1
