Description

Technical Field

[0001] The utility model relates to the technical field of electrode needles, in particular to a buckled water level electrode needle for a boiler. Background Art

[0002] The principle of the water level electrode probe is mainly based on the conductive properties of the liquid. The change of water level is measured by measuring the difference in conductivity between the liquid and the electrode. The water level probe is usually composed of two electrodes, one is located at the bottom of the liquid, and the other is located above the liquid and isolated from the bottom electrode in the liquid. When the liquid contacts the electrodes, a conductivity path is formed between the electrodes. The conductivity of the liquid increases with the increase of the water level because the rise of the liquid causes the number of ions in the liquid to increase, thereby increasing the conductivity of the liquid. By measuring the change in current, the height of the water level can be determined. This principle makes the water level Electrode probes are widely used in many fields, such as water treatment systems, pools, reservoirs, dams, and liquid level control in chemical processes. In actual applications, water level electrode probes are usually composed of one or more electrodes. When the liquid level rises to the position of the electrode, a conductive path is formed between the electrode and the liquid, thereby closing the circuit. By detecting the closure of the circuit, the height of the liquid can be determined. At the same time, the water level electrode can also perform multi-point measurements as needed to achieve simultaneous monitoring of different liquid heights. This principle is simple and intuitive, but some issues need to be paid attention to in actual applications to ensure accurate measurement.

[0003] However, the traditional water level electrode probe cannot meet people's needs, and it has the following defects: First, it is not designed with an anti-air leakage or water leakage structure. For the boiler water level electrode needle, it needs to be placed below the water level when in use. Water leakage or air leakage will have a great impact on the measurement results, affecting the accuracy of the measurement results, and at the same time causing damage to the internal components, reducing the service life; second, it is not designed with a simple electrode needle body. For the boiler water level electrode needle, a large number of different components are added to make the electrode needle have diverse functions, but at the same time it causes an increase in cost and an increase in volume. The excessively large space occupied makes the electrode needle not have priority selectivity, which will bring unnecessary trouble to the user in daily use. Utility Model Content
