The thermal radiation of the sun, excessive heating steam or electric heating can make safety showers use point temperature becomes very high, the consumer to be scalded. (iron valve installed in the safety showers, eye bath and other medical devices may be excessive heating water system, 1, through the sense of water temperature in pipeline, the hot valve will automatically open, put off the hot water, when the temperature down to set temperature gradually closed again. This process will be circulation according to the need for, and at the same time of preventing hot discharge water to maintain minimum. 2, through the sense of water temperature in pipeline, when using the water temperature is less than 39, 40 degrees on iron valve will automatically open, when using the water temperature is higher than the 41 degrees, the hot valve automatically shut down, prevent heat the water out, cause harm to human body.)
