Anti-freezing emergency shower & eye wash, EEWS-308

Description

1. Adopt the new patented eye wash spray head.The outlet water flow of the eye wash spray head is controlled by the flow regulation structure inside the spray head,it has been debugged and corrected before leaving the factory. If the water pressure on site changes, it can be adjusted by itself.
2. The main water inlet valve is a special three-way ball valve. The water inlet is opened (opening angle 90°), the outlet is closed; move the switch handle upward, the water inlet is closed, the outlet is opened, and the accumulated water in the pipeline is automatically emptied.
3. The pipeline is equipped with a water leakage hole to empty the residual water in the eye nozzle, which is conducive to the cleaning and anti-freezing of the pipeline (a part of the water is drained into the sewer pipe during eye washing without affecting the use effect).
4. The eye wash has the function of manual emptying and anti-freezing. It is suitable for use in areas where the temperature is below 0°C and in environments with hot water supply.
5. The inlet part and outlet part are customizable
6. Shut off valve and filter are proposed to be equipped on the water-supply end
7. Optional anti-scalding valve: The anti-scalding function of the eyewash can be customized. This anti-scalding valve is the main accessory, and a small part of the structure of the eyewash needs to be changed.

Working principle of anti-scalding valve A thermal element is installed at the mixing outlet of the constant temperature water mixing valve, which uses the characteristics of the temperature sensing element to promote the movement of the valve core in the valve body and block or open the water inlets of cold and hot water. Turn on the hot water while blocking the cold water. When the temperature adjustment knob sets a certain temperature, no matter how the inlet temperature and pressure of cold and hot water change, the proportion of cold and hot water entering the outlet also changes, so that the outlet temperature remains constant. The temperature adjustment knob can be set arbitrarily within the specified temperature range of the product, and the water mixing valve will automatically maintain the outlet temperature. Note: After setting the temperature, turn it on when the temperature is low and turn off when the temperature is high to avoid burns.
