Solar vacuum tube explosion safety pneumatic valve specific functions and advantages

at present in the field of solar water heating, vacuum tube type solar water heater is widely used, including the roof of the traditional one-piece solar water heater, also including into the union of tube solar collector, because of its relatively low initial investment, so the most widely used in the field of solar energy hot water. But it also has serious disadvantages limiting its use prospects. One of the most serious problem is that once in the system as long as there is a vacuum tube burst, will make the whole solar hot water system down for lack of water. At the same time, falling high hot water once hurt just passing pedestrians, the consequences will be more serious.
solar vacuum tube explosion safety pneumatic valve can not only effectively prevent the tube is hot and cold shock blast pipe problem, namely common vacuum tubes crack problem, at the same time, the pneumatic valve can also be in the vacuum tube for other reasons fry automatically shut down when the leak vacuum tube, prevent the solar water heater or solar hot water system for a large number of leaking paralyzed or cause safety accidents. Solar vacuum tube explosion safety of pneumatic valve installation position is the mouth of the solar vacuum tube end, and then insert with solar vacuum tube solar league header or in the solar energy water heater tank. In vacuum tube type solar water heater or solar hot water systems have a vacuum tube burst, the pneumatic valve can automatically shut off from the solar water heating system or solar water heater in the hot water by vacuum tube burst out, not only ensure the solar hot water system and running stability of the solar water heater, also avoid the leakage accidents caused by hot water. At the same time, the security of pneumatic valve in the vacuum tube solar water temperature and solar hot water system in the header or the solar water heater tank water temperature has a larger temperature difference, which can effectively cut off hot and cold water in vacuum tube mouth when the impact on the vacuum tube, completely eliminate the mouth due to the large temperature difference as a vacuum tube burst. Thereby significantly reducing the nature of the solar vacuum tube burst happening. The solar vacuum tube can be realized in the blast pipe, there is could prevent leakage during solar vacuum tube burst accident. Solar water heaters and solar hot water system can be enhanced greatly the safety coefficient and application scope.
solar vacuum tube explosion safety pneumatic valve has the advantages:
. Due to the safety of pneumatic valve has simple structure, so the cost of pay is low, basic don't increase the cost of water heater;
. The safety pneumatic valve adopts the simple mechanical structure, no complicated electronic equipment, is very reliable and practical;
. The environmental safety pneumatic valve selection economic security material high temperature resistant reinforced nylon manufacturing, ensure the safety of water;
. The pneumatic valve does not contain the metal parts, no corrosion in the water, fouling, long service life, safe and reliable;
. The safe working principle of the pneumatic valve is simple, easy to customers understand and accept, marketing is more convenient;
. The security pneumatic valve excellent versatility, can be directly with existing on the market of solar engineering header and solar water heater, no extra cost of equipment modification.
