Description

Technical Field

[0001] The invention patent relates to the technical field of reed electric contacts, specifically a high-voltage reed electric contact device. Background Art

[0002] Reed switch electric contacts are mainly used in pressure gauges as an alarm trigger mechanism when the pressure gauge reaches the set value. By setting the reed switch electric contacts in the pressure gauge, the upper and lower limits of the pressure gauge are set by the limit part according to the on-site conditions. The pressure gauge needle drives the movable part of the electric contact to move synchronously. When the pressure gauge needle reaches the upper or lower limit set by the electric contact during the use of the pressure gauge, the needle drives the movable part to trigger the reed switch to connect, thereby triggering the alarm path.

[0003] After the existing reed switch electrical contacts adjust the upper and lower limits, the limiter is prone to deviation due to gravity or vibration generated in the on-site production environment, resulting in instability after the upper and lower limits are set.

[0004] In addition, due to the complex production environment, the warning light and reed switch of the pressure gauge are prone to poor contact or damage due to environmental factors, resulting in the warning light not lighting up even when the needle reaches the upper or lower limit set by the electrical contact, and failing to serve as a warning. It is impossible to check whether the warning light and reed switch are abnormal, and it is difficult to determine whether the pressure warning function of the pressure gauge is normal enough.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0024] 1. After the reed electric contact device is installed on the pressure gauge, press the button into the sleeve, which drives the inner tube to squeeze the spring through the extension rod, and the inner tube drives the two pressure rings away from the sleeve ring 1 and the sleeve ring 2 through the through rod. At this time, the sleeve ring 1 and the sleeve ring 2 are not restricted by the pressure ring. Turn the button to make the main body 2 rotate as a whole in the sleeve, and the folding rod rotates with the main body 2. The folding rod is used to turn the limit part 1 to rotate, so as to adjust the position of the limit part 1, that is, to adjust the limit value of the limit part 1. Similarly, the folding rod can also turn the limit part 2 to rotate, that is, to adjust the limit value of the limit part 2. In actual application, the limit part 1 can be used to adjust the minimum value, the limit part 2 can be used to adjust the maximum value, or the limit part 1 can be used to adjust the maximum value, and the limit part 2 can be used to adjust the minimum value;

[0025] 2. After adjusting the limit value, release the button, the spring returns to its original position, the main body 2 is reset as a whole, and the two pressing rings press the sleeve ring 1 and the sleeve ring 2 to prevent the limit part 1 or the limit part 2 from deviating due to gravity or vibration generated in the on-site production environment, resulting in instability of the set limit value;

[0026] 3. After the maximum and minimum limit value adjustments are completed, when the needle on the dial rotates to near the limit value, the lever 1 or lever 2 will be moved. If the lever 1 is moved, the spring piece 1 will be deformed, and it will drive the permanent magnet 2 to approach the reed switch 1 on the limit part 1 through the long rod 1. Under the influence of the magnetic field of the permanent magnet 2, the reed switch 1 is connected, and the warning light is on, indicating that the pressure of the device detected by the pressure gauge has reached the limit value set by the limit part 1. If the lever 2 is moved, the spring piece 2 will be deformed, and it will drive the permanent magnet 3 to approach the reed switch 2 on the limit part 2 through the long rod 2. Under the influence of the magnetic field of the permanent magnet 3, the reed switch 2 is connected, and the warning light is on, indicating that the pressure of the device detected by the pressure gauge has reached the limit value set by the limit part 2.

[0027] 4. When the button is rotated in the direction of reed switch one, it drives permanent magnet one to rotate to the vicinity of reed switch one through the folding rod. If there is no fault in some reed switch one, it will be connected under the influence of the magnetic field of permanent magnet one. If the warning light is not faulty at this time, the warning light will light up as usual. Otherwise, if the warning light is not on, it can be quickly found that there is a fault in reed switch one or the warning light, which can be quickly checked, repaired or replaced to ensure the normal warning function of the reed electric contact device. In this way, it is possible to check whether there is a fault in reed switch one, reed switch two and the warning light to ensure the normal warning function of the reed electric contact device.
