One reason is that the tightening force of the bolts on the joint surface is insufficient or biased, resulting in poor sealing of the joint surface.The elimination method is to adjust the tightening force of the bolt. When tightening the bolt, it is necessary to tighten it diagonally. It is best to measure the gaps at all points while tightening, tighten the bolt until it cannot be moved, and make the gaps at all points of the joint surface consistent.

The second issue is that the tooth shaped sealing gasket on the joint surface of the safety valve body does not meet the standard. For example, slight grooves, poor parallelism, sharp or sloping teeth in the radial direction of the toothed gasket can cause sealing failure. Thus causing leakage at the joint surface of the valve body. By ensuring the quality of spare parts during maintenance and using standard toothed gaskets, this phenomenon can be avoided.

The third reason is that the flatness of the joint surface of the safety valve body is too poor or it is blocked by hard impurities, resulting in sealing failure. The method to eliminate leakage caused by poor flatness of the valve body joint surface is to disassemble the valve and re grind the joint surface until it meets the quality standards. If the seal fails due to impurities blocking, carefully clean the joint surface during valve assembly to prevent impurities from falling in.
