Water level electrode

Abstract

The invention relates to a water level electrode. The water level electrode comprises a sealing rod, wherein a sleeve is arranged outside the sealing rod; the outer wall of the sealing rod is provided with a boss ring; a stepped hole which is matched with the boss ring is formed in the sleeve; the sleeve is sleeved on the boss ring on the outer wall of the sealing rod; a sleeve screw is arranged in the stepped hole of the sleeve and sleeved on the outer wall of the sealing rod; a connecting rod is arranged in the sealing rod; both the ends of the connecting rod are extended out of the sealing rod; one end of the connecting rod is provided with a compression nut through which a signal line is connected with the connecting rod, and the other end of the connecting rod is connected with one end of a connecting column; and the other end of the connecting column is connected with one end of a probe. The water level electrode is suitable for detecting the height of water level in containers such as a boiler and the like.

Description

technical field [0001] The invention relates to the structural technical field of water level electrodes. Background technique [0002] The water level electrode is the main tool used to detect the water level in boilers and other containers. Such as Figure 4 As shown, the structure of the traditional water level electrode includes a probe 1, the outside of the probe 1 is covered with a sealing rod 2, both ends of the probe 1 protrude from the outside of the sealing rod 2, and the upper end of the probe 1 connects with the signal through a nut 3. The wire 4 is connected with each other, and a sleeve 5 is arranged on the outside of the sealing rod 2, the sleeve 5 is connected with the sealing rod 2 through an internal thread, and the sleeve 5 is fixed with the container through an external thread. The working principle of the traditional water level electrode is: set several water level electrodes with different heights inside the container, and the lower end of the probe 1...

AI Technical Summary

Problems solved by technology

The disadvantage of the traditional water level electrode is that the commonly used water level electrode will have serious leakage due to the relatively high pressure, temperature and humidity and the long-term alternating heat and cold environment.

The leaked water vapor overflows everywhere, which will cause a short circuit between the probe 1 and the container, resulting in the failure of the water level electrode detection and causing great safety hazards to the operation of boilers and other containers

Generally, if the water level electrode leaks, the entire water level electrode must be removed and replaced to achieve the sealing effect, which is very inconvenient to maintain and increases the cost
