This  valve is generated by the pipeline flow of the medium itself force automatically turned on and off, is an automatic valve. Check valve for pipeline system, its mainrole is to prevent the media back, to prevent the pumpand drive motor reversal, and the container medium discharge. A one-way valve is only for unidirectional flow control, not as safety relief device.

Q: What is the difference between photovoltaic products and solar energy?
But in general, as many of the world's oil and gas production areas of political and economic instability, many governments are taking active measures to reduce dependence on foreign energy sources. Solar energy provides an attractive power generation program, and will not form a serious dependence on foreign energy. In addition, the increasingly serious environmental problems and fossil fuel power and political reasons of climate change risk formation, prompted the government to implement the aims to reduce carbon dioxide and other greenhouse gas emissions reduction strategy. Solar energy and other renewable energy sources contribute to the solution of these environmental problems.
Q: Solar garden lamp product parameters
* storage battery: fully enclosed maintenance free lead-acid battery 15V20Ah - 80Ah* light source type: energy saving high power integrated LED, rare earth high efficiency energy saving lamp* protection level: IP65* use temperature: -30 degrees to 70 degrees, wind resistance is more than 150Km/h* lighting time: adjust as needed* pole height: according to need
Q: Product category and comparison of solar thermal utilization
What is the reason?The main reason is that China's solar energy (water heater) is the most in-line vacuum tube solar water heater, vacuum tube itself is vulnerable, tube explosion caused by vibrations, icing, improper water and other reasons, the vacuum tube fouling phenomenon is very serious, affecting the normal use, needs a great amount of customer service service, high maintenance costs. Once, encountered bad weather, frequent accidents, too busy to attend to all enterprises and dealers.Where is the way out?According to the experience and lessons of foreign countries, the use of a new type of high-performance flat solar energy is the most feasible and effective solution.
Q: As a new energy solar energy has attracted more and more attention has been paid more and more practical application at home and abroad, I really want to know what are the solar energy application is very hope that we put forward their own views and even science fiction book that I want to do research on solar solar energy market in the military and political life etc.
Uses as follows:Photothermal utilizationIts basic principle is to collect the solar radiation energy, and convert it into heat energy. At present, the most widely used solar collector, there are 4 types of flat plate collector, vacuum tube collector, ceramic solar collector and focus collector (trough, dish and tower). Usually according to the temperature and the use of the different, and the use of solar thermal light is divided into low temperature (<200 DEG C), the use of medium temperature (200 ~ 800 C) and high temperature utilization (>800 C). At low temperature using mainly solar water heater, solar dryer, solar distiller, solar heating (solar room), solar greenhouse, solar air conditioning system, the temperature is mainly using solar cookers, solar thermal power generation heat collecting device, mainly using high temperature high temperature solar furnace etc..
Q: Solar electric vehicle charging device
Electric vehicle solar energy products are small in size, light in weight, easy to install and carry. Is a domestic initiative, has applied for national patent. Market potential is very large, very broad prospects.
Q: Solar energy products, that is, I would like to open a home solar products Daquan
Photoelectric, two large blocks of light and heat, I think it will be a complete. But a lot of financial strength to do it
Q: Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?
Mobile phone battery as an energy reserve, but no 5V output boost function, the same can not charge the phone. If you have bought a solar panel, you can buy a mobile power with the use of
Q: Now there is no sun, cloudy days can use solar products?
In addition, if you are a household, engage in electric heating can be complementary to each other!
Q: What is the difference between the expensive solar energy and the cheap one?
Give you an example, for example, the same car, are four wheels, but Mercedes Benz and Xiali price is much worse, because Mercedes Benz safety good quality is high, can ensure the safety of life, your value
Q: Solar energy application technology, there is no prospect
However, from a policy point of view, there is no industry like solar energy so much attention by the country. Compared with the traditional fossil energy, solar energy has obvious advantages. Therefore, the prospects are good.In a word, the future is bright, the road is tortuous!!
