Combination of surface leakage valve body

   Refers to the combination of upper and lower body at the surface leakage, leakage of the main reasons for this are the following aspects:
   First, the combination of bolt tightening force plane is not enough or tight side, causing a bad combination of surface sealing. Elimination method is to adjust the bolt tightening force, we must act upon the bolts diagonally to tight manner, preferably tight side edges around gap measure, tighten the bolts to tighten stops, and combined with a gap around the face unanimously.
   Second, the combination of the tooth surface oven safety valve body gasket does not meet the criteria. For example, there is a slight radial profile gasket grooves, parallel to the difference, too sharp or too sloping tooth defects can cause seal failure. So that the valve combination of surface leakage. In the maintenance of the good quality spare parts, the use of standard tooth profile gasket can avoid this phenomenon.
   Third, the valve body joint surface flatness poor live or hard pad impurities cause seal failure. As the body of the method combined with the flatness of the surface of the body caused by bad combination of surface leakage, eliminate
Is the valve until the disintegration of the joint surface reground meet quality standards. Due to impurities caused by seal failure pad to live in the Burner Valves assembly carefully cleaning the joint surface to avoid falling into impurity.
