Anti freeze valve is designed for the development of solar water heater accessory products, its main function is to prevent the solar water heater set hot plate is damaged. Antifreezing valve installed in the heat collecting plate of solar water heater (as shown in schematic diagram, use) when temperature decreases to about 4 DEG C, the antifreeze valve is opened, the water collector can be discharged in time; and replenish the water warm water box to the heat collecting plate. When the warm water reaches the anti freezing valve, the anti freezing valve closes automatically.First, the characteristics of solar anti freezing valve:1, automatic protection: anti freezing valve through the temperature of the temperature generated independent action, without outside power can be automatically opened and closed, so as to protect the safety of solar water heater collector plate.2, high control precision: anti freezing valve opening temperature of 4 + 1.3, easy to install: the use of universal G3/4, G1/2 pipe thread interface.4, compact structure, beautiful appearance.Solar anti freezing valve product maintenance, in order to make the antifreeze valve can work properly, should be regularly cleaned to enter the anti freeze valve internal impurities and sediment.Solar anti freezing valve technical parameters:Factory set temperature: 4 degree control accuracy: + 1 C voltage: 10bar, operating temperature range: 1.7Specifications: DN15, DN20 body material: brass, spring material: stainless steel 304 seal material: EPDM, surface treatment: sand blastingTwo, pipeline antifreeze valve product introduction:The safety anti freezing valve prevents the water system from freezing, and avoids the damage of the water tank or the pipeline caused by freezing. It used in solar energy, outdoor living water system. When the ambient temperature is reduced to about 4 degrees, the antifreeze valve opens, the safety anti freezing valve automatically opens to maintain a part of the water flow out, the minimum flow rate to prevent the end of freezing. When the environment temperature rises or the water temperature rises, the safety anti freezing valve closes automatically, and returns to the normal working condition. The water tap and the safety anti freezing valve are combined into a whole, and the installation is simpler, and the water system is suitable for outdoor heat preservation measures.The characteristics of pipeline frostproofs _ products:1, automatic protection: anti freezing valve through the temperature of the temperature generated independent action, without outside power can be automatically opened and closed, so as to protect the safety of water system.2, high control precision: anti freezing valve opening temperature of 4 + 1.3, easy to install: the use of universal G3/4, G1/2 pipe thread interface.4, compact structure, beautiful appearance.Three, pipeline antifreeze valve working principle:Anti freeze valve safety valve is built in contact with the ambient temperature of the thermal element (1) to control the piston (2) and between the opening and closing of the valve seat. When the ambient temperature is lower than the set value, the thermosensitive element by the contraction of the piston downward open the drainage channel, the very small part of the water discharged from the continuous flow of water to avoid freezing pipe. The water temperature in the pipeline in the flow, the temperature is usually higher than the outside air temperature, when the temperature exceeds the set value when closed, thermistor expansion drives the piston upward closure discharge channel. System restore normal operation state. In order to ensure the good running state of anti freezing, the upper reaches of the safety anti freezing valve should be guaranteed.
