AI Technical Summary

Technical Problem

Existing bimetallic steam traps are prone to problems such as untimely drainage or steam leakage when the load changes or the pressure difference fluctuates, which leads to reduced system thermal efficiency and increased energy consumption.

Method used

The system employs a combination design of Venturi hydrophobic modules and bimetallic hydrophobic modules. The Venturi hydrophobic module achieves accurate separation of condensate and steam through a nozzle made of polymer material, while the bimetallic module initiates auxiliary drainage when the system fluctuates. Combined with the Laval section, it enhances the hydrophobic capacity and enables online maintenance through a filter screen and an emergency opening and closing mechanism.

Benefits of technology

It achieves continuous and stable discharge of condensate, enhances adaptability to pressure fluctuations and load changes, avoids steam leakage, and improves system thermal efficiency and energy saving.

Abstract

This invention discloses a single-seat high-efficiency energy-saving steam trap, comprising a Venturi steam trap module and a bimetallic steam trap module. The Venturi steam trap module includes a valve body and a Venturi nozzle. The valve body has an inlet channel and an outlet channel at its left and right ends, respectively, and an upper chamber and a lower chamber at its upper and lower ends, respectively. The lower chamber is connected to the inlet channel and the outlet channel via a main drainage channel one and a main drainage channel two, respectively. The upper chamber is connected to the inlet channel and the outlet channel via auxiliary drainage channels one and two, respectively. The bimetallic steam trap module is installed in the upper chamber, and the Venturi nozzle is installed in the lower chamber. The end of the Venturi nozzle near the main drainage channel one has a contraction section with a gradually decreasing axial cross-section. A throat with a constant inner diameter is axially continuous at the inner end of the contraction section. This invention can accurately separate condensate and steam, achieving not only continuous and stable drainage but also superior energy-saving performance.
