The firewood valve is difficult to achieve the effects of the pipeline itself and the springs equipped with the pipeline itself when the fire discharge effect is difficult to achieve the effects of smooth smoke discharge.It is widely used in various buildings.There are three differences between common fire valve and smoke fire prevention valve: different levels of shutdown, different installation positions, and different opening status.
1. Different number of closures
In addition to the different positions of the firewood valve and smoke exhaust fire valve, the function of use is different, and its own device structure is different, and the closed temperature is also different.The fire prevention valve is generally used in smoke -proof, so it is necessary to automatically close at 70 ° C, and isolate foreign smoke and dust pollution. Therefore, it is also called a 70 -degree fire prevention valve or directly referred to as the fire valve.The smoke -type fire valve is mainly used to eliminate smoke and dust. In order to avoid the affected personnel escape when there is smoke, it is generally closed when it is 280 degrees Celsius. Because of the high temperature of 280 degrees Celsius, it is also being affected.Called high -temperature fire prevention valve.
2. Different installation location
The fire prevention valve is mainly placed in the structure of ventilation and air -conditioning systems. It is generally common in ventilation pipelines. Its role, as its name implies, is to prevent the spread of smoke in the fire from spreading to other places.EssenceIts principle is to identify the dust content in the place where the fireworks detectors are perceived by the thermal energy in the fireworks, so it is necessary to install it in the ventilation pipeline to detect the dust and dust.The smoke discharge fire prevention valve is generally installed in the smoke exhaust pipeline. Its role is mainly to eliminate the smoke caused by the fire. The principle is to use the pressure of wind pressure to discharge high -concentration smoke and dust from the building. Therefore, it is installed on the discharge.Only in the tobacco pipeline is conducive to centralized emissions, thereby ensuring that the quality of the internal building is qualified.
3. Different state of opening
In order to prevent the entry of smoke and dust, the fire valve is usually closed, and it cannot be opened at will otherwise it will cause indoor environmental pollution.In the case of smoke -proof, in order to isolate the smoke, the fire valve can be manually turned on to avoid emergency emergencies that cause indoor air to not circulate.The smoke and fire prevention valve mainly eliminates the smoke and dust in the place, so it is usually turned on, and the free shutdown will cause indoor air to block.Only when the fire reaches 280 degrees Celsius, the smoke and fire prevention valve will be automatically closed.In the absence of smoke, there is no way to open the internal high -concentration of smoke and dust, which is not a way to open it manually, which is also due to security considerations.
The above is a brief introduction to the difference between fire prevention valves and smoke fire prevention valves. I hope that the above content can be helpful to everyone. Thank you for your viewing and support. In the later period
