An antifreeze liquid level gauge

Abstract

An antifreeze liquid level gauge, the upper and lower ends of the glass tube are respectively provided with connecting pipe assemblies with lateral connecting pipes, the upper and lower connecting pipe assemblies in the glass pipe are connected with heat dissipation pipes, and the upper and lower ends of the heat dissipation pipes are connected with each other. There are short pipes with side inlets and outlets. The inlets and outlets are connected with a partition wall heat exchanger that matches the boiler body used. The high temperature liquid outlet of the partition wall heat exchanger is connected with the above inlet. The low-temperature liquid inlet of the heat exchanger is connected with the above-mentioned outlet, the lower nozzle of the lower short pipe is connected with the liquid storage tank above the partition wall heat exchanger and the cooling pipe, and the upper nozzle of the upper short pipe is connected with the upper part of the liquid storage tank. There is a snorkel. The invention has a connected partition wall heat exchanger and heat dissipation pipe, the partition wall heat exchanger is matched with the pot body of the boiler used, the heat dissipation pipe is in the glass tube, and the heat of the high-temperature liquid in the pot body is used to indirectly heat the liquid in the glass tube of the liquid level gauge In order to prevent freezing, it does not consume electric energy during use, which is beneficial to use in explosion-proof places and is not prone to failure.

Description

Technical field [0001] The invention relates to a communicating device type liquid level gauge for a boiler, in particular to a heat preservation and antifreezing device of a communicating device type liquid level gauge for a boiler. Background technique [0002] A boiler is a device that provides high-temperature liquid to external equipment. The boiler has a container-shaped boiler body with a heat exchanger in the boiler body. When in use, a certain amount of liquid is contained in the pot body, and the heat exchanger heats the liquid in the pot body into a high-temperature liquid to provide high-temperature liquid to external equipment. The boiler is made of steel. In order to prevent the boiler body from losing heat, the outer wall of the boiler body is covered with a layer of insulation material. When the boiler is running, the liquid level in the boiler body must be at a certain height, otherwise a safety accident may occur. In order to be able to observe the liquid leve...

AI Technical Summary

Problems solved by technology

[0008] This kind of antifreeze liquid level gauge uses electric heating tape to heat the glass tube. When in use, the liquid level gauge is in a charged state, which not only consumes electric energy, but also is not conducive to the use in explosion-proof places, and is prone to failures that affect use.
