Problems solved by technology
[0002] When using a valve for ventilation, because the passage of gas is often accompanied by high heat and high flow rate, the interior of the valve will be in a state of high temperature and high pressure. It will not always be consistent with the flow rate. In special cases, it will exceed the specified value on the valve. At this time, if the transmission air guide valve is used, the traditional air guide valve has a single function. If the ventilation volume to be used is set in advance Finally, even if it is necessary to change the flow rate in a small area, manual operation is required, which is very inconvenient. At the same time, the traditional valve has no obvious control ability on the internal heat of the valve, and it will be more easily damaged under special circumstances; therefore, there is an urgent need for a device to solve the problem. Such problems

The invention discloses a circulating gas guide valve which comprises a valve body. A gas guide hole is formed in the valve body in a left-and-right through manner. A heat inductance trigger mechanismis fixedly arranged at the right end of the gas guide hole. A temperature inductor is fixedly arranged at the top end of the heat inductance trigger mechanism. The heat inductance trigger mechanism comprises a heat conduction pipe fixed between the upper end wall and the lower end wall of the right end of the gas guide hole. According to the circulating gas guide valve, equipment operation is simple; the heat inductance trigger mechanism is used for carrying out heat detection on gas flow passing through the valve; when the heat is too large, an exhaust valve is used for additional exhaust, the temperature is prevented from being increased, and safety and reliability are achieved; and meanwhile, the force storage trigger mechanism cooperates with a ball valve gas control mechanism, the situation that valve components are damaged and fail due to the too high gas flowing speed is avoided, the service life is long, the temperature of gas in the valve can be directly indicated by the temperature indicator, and operation is simple and clear.
