Today, I will introduce to you what are the reasons for the binding surface leakage of the smoke exhaust firewood valve?
1. The tightness of the connecting head and surface bolts is not good or the fastener deviations are large, resulting in poor sealing of the connection surface.This may be caused by insufficient bolt tightening or improper tightening method.The solution is to adjust the tightening force of the bolt and use diagonal tightening to ensure that the space of the entire ground is completely covered.
2. The binding surface of the fired fire valve body is too poor or has a hard impurities filling, forming a sealing failure.When the flatness of the valve body binding surface is poor, it may cause leakage.The solution is to polish the binding surface from the beginning to meet the quality requirements and avoid the sealing failure caused by impurities pads.
3. Tobacco -fire prevention valve body combined with surface tooth -shaped pads does not meet the requirements.This may be caused by the axis directional grooves, poor plane degree, pointed teeth, or cross -slope.The solution is to use the required tooth -shaped pads, and pay attention to the quality control of the gasket.
The above is the reason for the binding surface leakage of the smoke exhaust fire valve body. I hope that the above content can be helpful to everyone. Thank you for your viewing and support. In the later period, more information will be sorted out. Please pay more attention to us ——
