Клапан-пульсатор

Abstract

A valve-pulser is arranged as a one-stage two-stroke controlled automatically operating hydro-dispenser, with axial reboring in the body where the shutoff element of cup type is arranged with changing lift area, this is formed by the conical part of the shutoff element pressed by pressing force of the controller spring; this in its turn is placed in the cavity of the spring controller; the pressure cavity and the grab cavity are formed by the form of the bode and the conical part of the shutoff element, to he housing of the valve-pulser there are connected the pressure main line to the pressure cavity and the discharge main line to the window for the working liquid discharge in the housing of the valve-pulser, this connects it to the hydro-tank; at that the shutoff element is arranged as a two-step shaft conjugated with its cylindrical surfaces to the axial reboring of the housing, and the spring of the controller is placed between the wall of the body and the end of the cylinder with smaller diameter of the shutoff element, and between the larger in diameter end of the cylinder and the end of the cylinder of the shutoff element and the surface of the reboring of the housing there is formed a pressure-discharge cavity of the slide bringing back to the initial position, this is connected by the inner hydro-channels of the shutoff element to the pressure hydro-line and the controlled accumulator.
