During the use of the gas solenoid valve, it is often unable to close due to various problems.

According to the thermocouple indexing number B, S, K, E and other thermocouple temperature corresponding to the millivolt (MV) value, at the same temperature, the generated millivolt value (MV) B index number is the smallest , S index number is the smallest, K index number is larger, E index number......

First of all, thermocouple is a commonly used temperature device in temperature measurement.

Solenoid valves are valves that use electric power and magnetic force to control, including but not limited to liquid and gas pipelines, and are currently popular in the market.

The use in production is becoming more and more extensive. Thermocouples have become one of the most commonly used temperature detection components in the industry.

The errors introduced by the deterioration of the insulation, such as the insulation of the thermocouple, and the excessive dirt or salt slag on the maintenance pipe and the cable plate, cause poor insulation between the thermocouple poles and the furnace wall,
