Range hood check valve

The "check valve", also called "butterfly-valve", function is to allow air to one-way flow. Check valve is located in smoke lampblack machine turbofan (motor), before entering the exhaust duct, is wary of outdoor blowing winds, due to the instantaneous pressure difference between inside and outside, let outdoor air be "sucked" into the room. In theory, however, is "check valve", in a common case, it can only be "reduced valve" and not "check". Now a lot of people who live in multi-storey apartment buildings all complaints in their interior smell of other dishes.Reason is that at the bottom of the kitchen lampblack machine to lampblack to the vertical exhaust hole, because most of the building design and useless to the shaft caused "negative pressure", so the soot in the shaft up downstairs "squeeze", on the way will leak into other floors lampblack machine exhaust pipe.Because of the check valve can't be 100% sealing, the smoke nature can seep into the house.

History of valve

The valve is produced with the flow of the fluid pipe. Human use of the valve has been nearly 4000 years of history. Chinese ancient salt brine from salt in absorption, once in the bamboo pipe used in cork valve. In the 1800 BC, the ancient Egyptians used similar wooden plug to control the flow of water in order to prevent the Nile flood. These are the valve prototype. Industrial use of the valve is a large number of applications, from the beginning of the invention of the steam engine Watt. At the beginning of twentieth Century has cast iron, cast steel, forged steel, stainless steel, chrome molybdenum steel, brass and other materials in the valve. Application in various industries, various conditions. The earliest introduction of foreign valve production technology company is not much, after the introduction of foreign production technology, making the domestic valve production technology breakthrough, the quality of the increase, the longevity of the extension.
According to the "2013 China valve industry competition development bottleneck" in the show: with the valve industry to accelerate the pace of restructuring, the industry will be the valve product quality safety and product brand competition between products to high technology, high parameters, high resistance to corrosion, high life direction, only through continuous technological innovation, development of new products, technological transformation, to gradually improve product technology level, to meet domestic equipment supporting, the full realization of the domestic valve. China's valve manufacturing industry in a huge demand environment, will show a better development prospects.
At present, China's valve market turnover of up to 50000000000 yuan, which fully shows the size and momentum of the development of the valve industry in china. But in the industry situation in a good background, there are some problems worthy of our concern, especially in China's valve business mainly in the low level, small scale, family business oriented enterprises. This is a great limitation and bottleneck for the future development of the valve industry in China.
At present, the domestic valve manufacturing enterprises have been able to ISO international standards, DIN German standard, AWWA American Standard and other international standards for design and manufacture of various valves, some manufacturers of products reached the international advanced level. Although the new year's overall level of the valve industry has been greatly improved, but the quality is still not stable enough, such as run, run, drip, leakage phenomenon in the domestic valve often occur.
In addition, the matching capacity of the valve with the developed countries, there is still a certain gap. Valve market competition is becoming increasingly fierce, some ordinary valve products market has been saturated, for more than a request, which makes the development of small and medium enterprises increasingly difficult. And even the high technology products in the international market is also very fierce competition.
Our country in the valve market, has been able to provide heating valve, environmental protection valve, construction valve, etc., more varieties.

The working principle of pressure reducing valve

Pressure reducing valve is a kind of special device, reduce the working pressure pipeline automatically, it can be by high water pressure reducing valve before pipe to the valve pipe after the required level. Pressure reducing valve is widely used in high-rise buildings, the area of urban water supply pipe network pressure is too high, mines and other occasions, to ensure that each water point in water supply system water pressure and flow to have the appropriate services. In view of water leak rate and degree of waste almost as the water pressure is directly proportional to the size of feed water system, thus reducing valve have improve system operation condition and potential water-saving effect, according to statistics, the water-saving effect is about 30%.

The structure of the pressure reducing valve type many, common in the past have a spring in the diaphragm, piston, etc. Within the basic principle of the pressure reducing valve by valve port on the local resistance to reduce the water pressure, water pressure drop by connecting disc film or the scope of import and export pressure difference on both sides of the piston automatic adjustment. In recent years appeared some new type pressure reducing valve, such as constant ratio type pressure reducing valve, the construction principle as shown in figure 14.2 2. Constant ratio reduced pressure principle is to use the body of the floating piston hydraulic pressure ratio control, import and export side pressure ratio is inversely proportional to the import and export side piston area ratio. The pressure reducing valve work smoothly without vibration; The body without the spring, so no spring rust, metal fatigue failure were evident; Good sealing performance, leakage and therefore reduced pressure (water flow) and reduction of static pressure (flow to 0); Especially in relief at the same time does not affect the water flow.
