Axial Venturi Drain

By using a liquid level gauge and control box in the drainage device and the parallel or series structure of the Venturi nozzle, the drainage amount is dynamically adjusted, which solves the problem that the existing traps cannot adapt to the changes in the condensate load, and achieves the effect of reducing steam leakage and improving the drainage efficiency.

AI Technical Summary

Technical Problem

The existing traps cannot effectively adjust the drainage amount when the condensate load changes, resulting in an increase in steam leakage and cannot adapt to changes in the steam pressure in the pipeline.

Method used

An axial Venturi hydrophobic device is designed, using a level meter to detect the condensed water level and adjust the hydrophobic amount of the hydrophobic structure through the control box, including a venturi nozzle connected in parallel or in series, to achieve dynamic adjustment of the hydrophobic amount.

Benefits of technology

The device can adjust the amount of water repellent according to the changes in the condensate load in the pipeline, reduce steam leakage, improve water repellent efficiency, and adapt to changes in steam pressure under different load conditions.

Abstract

The present invention discloses an axial venturi drain device, which includes a liquid storage tank, a first connecting piece is arranged on one side of the liquid storage tank, and a liquid level gauge for detecting the liquid level inside the liquid storage tank is arranged on the upper part of the liquid storage tank. The drain device also includes a drain structure and a control box, one side of the drain structure is fixedly connected to the liquid storage tank, and the other side of the drain structure is fixedly connected to a second connecting piece, the control box is electrically connected to the liquid level gauge and receives a signal from the liquid level gauge to adjust the drain volume of the drain structure, so that the amount of steam leaked from the drain device is small. After the first connecting piece and the second connecting piece are connected to the pipeline system, the discharge volume of the drain structure can be determined according to the discharge volume of condensed water in the pipeline under the detection of the liquid level gauge, thereby reducing the amount of steam leakage in the pipeline.
