SU121619A1 - Semi-automatic well-outlet for free-flow pipelines - Google Patents

Description

In the known wells-outlets, the kinetic energy of the flow in the distributor is first quenched to provide partial or full water intake, and then pressure is created to pass the transit part of the water flow. In the first case, a considerable well length is required to quench the energy of the water, and in the second case, an increase in the depth of the well and manual production of significant soil modifications at the outlet to the distribution channel is required.

In the proposed well-outlet, the kinetic energy is quenched only for the part of the water that is taken in with a pass without quenching the transit flow. For this, a perforated pipe with a throttle device is placed at the bottom of the well. A butterfly valve connected to the float automatically warns the emergency filling of the well.

The (Diagram shows a well-outlet in the section. It consists of a perforated metal nipple / with a throttle vane valve 2, vrash.ayush, it around the vertical axis 3, inserted into the recess at the bottom of the nipple and into the bearing 4. finger 5 with a horizontal handle 6, which regulate the opening of the throttle.

The handle is secured with a metal | Sky tank 7 without a bottom, acting as a load or float. In the case when the flow of water into the well does not threaten overflow, the tank serves as a weight, pressing the handle 6 to the concrete edge of the well in the desired position. If the level in the well rises above the allowable, the tank, playing the role of a float, will move the handle to the extreme position, ensuring the full opening of the throttle valve.

The water flow is controlled by the throttle valve (shutter) by moving the handle along the edge of the concrete well.

Subject invention

Claims (2)

1. A semi-automatic well-outlet for free-flow pipelines, characterized in that, in order to provide kinetic energy quenching only at the withdrawn part of the water, it uses a perforated pipe on a water supply pipe with a throttle vane valve near its outlet end in the well. 2. The water supply well according to claim 1, characterized in that, in order to prevent water from flooding the well, a handle with a float is placed on the continuation of the vertical axis of the flap, which, when supported by water in the well, somewhat floats and provides turning to the vane position by the flow of water in the pipeline.
