The realization of gas burner valve

In the modern industrial processes, pneumatic control gas Burner Valve applications are very common, and its role is also very important, related to industrial production safety and economy. In actual production, pneumatic control Gas Burner 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 Gas Burner 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 Gas Burner Valve normal operation, the gas source, signal source, any loss of signal will cause improper operation of the Gas Burner Valve. Therefore, in practical industrial processes, commonly used three off protection to ensure reliable operation of pneumatic control gas brass safety valve.

     In engineering practice, when the power failure, breathe, off signals of these three failures in one or several cases occur, pneumatic control Gas Burner Valve fully open Gas Burner Valve automatically considered based process safety factors, the fully closed Gas Burner Valve or Gas Burner Valve failure to maintain position before - three off protection. Among them, close the Gas Burner 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.
