The analysis on gas top burner valve

With its increasing emphasis on the living environment, environmental protection departments began slowly attention and control hazards of noise, and the introduction of the standards and norms related to limit noise. Noise largest industrial enterprise environmental standards is permitted 90dB, the actual noise when opening and closing the Range Top Burner Valve ordinary stove produces up to 120dB, seriously polluted the surrounding environment. After solving the finite element model to calculate the success of post-processing, obtained as shown in Figure 14 SPL cloud, can be seen from this figure the maximum sound pressure level is 79.2dB. It can be seen from the use of this new type of gas top burner valve noise level analog simulation side has to meet the requirements of the relevant laws and regulations to control the noise range, can be extrapolated hole injection is an effective noise of Burner Valve reduction method, but must choose hole aperture and reasonable arrangement.

How to protect the gas burner valve

In the modern industrial processes, pneumatic gas Burner Valves applications are very common, and its role is also very important, related to industrial production safety and economy. In actual production, pneumatic control valve in accordance with the requirements of the process system needs to adjust various parameters to meet the needs of industrial production. Especially in many important aspects, the pneumatic control valve if improperly adjusted it will destroy the entire production process and may cause huge economic losses. In general, the need to provide power when the pneumatic control valve normal operation, the gas source, signal source, any loss of signal will cause improper operation of the Stove Top Burner Valve. Therefore, in practical industrial processes, commonly used three off protection to ensure reliable operation of pneumatic control valves.
In engineering practice, when the power failure, breathe, off signals of these three failures in one or several cases occur, pneumatic control valve fully open valve automatically considered based process safety factors, the fully closed valve or valve failure to maintain position before - three off protection. Among them, close the valve and open the Range Top Burner Valve body can be used in the cylinder pressure and the reaction force of the spring easily achieved. Three break protection to secure his position in functions to achieve it, it is more complex, and therefore, the paper analyzed and compared to the three projects off the protector of two widely used to secure his position in the functional program.

Valve industry development status

Industrial production in various agricultural films, film, agricultural water-saving equipment, such as ball valves, Gas Top Burner Valve are widely applied in modern agriculture, rural applications are increasing pipeline valves, only to solve drinking water project with a valve pipe demand is considerable. Various needs of urban construction pipeline valves also greatly increased. Automotive industry uses valve manufacturing automotive components increased, the developed countries have an average power plant valves more than 10 billion, the average amount of power station valve of 7 billion, which stimulated the demand valve industry.

For domestic valve industry, the mainland and there is a big gap between the coastal mainland from a low valve industry, small-scale, low degree of specialization, market-oriented is not high, which widened the gap with the coastal areas, but also led to the unbalanced domestic valve industry development.

Domestic valve industry to get rid of the current predicament, break through the bottleneck constraints, to seek new space for development, the introduction of foreign advanced equipment and advanced technology, in order to arm themselves. Stopped their position in the fierce competition, is bound to take appropriate measures. It is reported that, in the next period of time, foreign investment will come into China's valve industry, which is no doubt the domestic Range Top Burner Valve industry is a strong stimulus.

In recent years, China's valve industry has entered a rapid development period, the valve industry, "threshold" gone has become Asia's largest valve machining center, one of the world's largest valve market. However, China's per capita consumption level valve products in the world is not high, currently only $ 22 per capita. But with the rise of the power station valves, chemical valves, valves, valves and other building materials and food, we can see that the valve industry prospects, market attractive.

With related diversified industries, depth development trend, identity valve products has gradually expanded to the broader industry by Commodity protagonist, the high-tech field of valve products put forward higher requirements. At the same time, a variety of products, environmental scrapped Gas Heater Control Valve treatment, recovery and recycling and other tasks will become increasingly difficult.
