Preventive maintenance of new valves before operation is an advanced construction idea, which aims to protect the sealing device of the valve seat and avoid the damage of the valve seat during installation, welding and operation. Preventive maintenance of the valve before it being put into use can not only help to find problems early and eliminate hidden dangers, but also prolongs the operation period of the pipeline and provides a better basis for the operation and maintenance of the valve after it is put into operation.
The leakage of valves mostly occurs at the initial stage of use, and the main reason is that the seal ring and the disc are scratched due to non-standard operation during pipeline construction. If these scratches are not repaired in time, the long-term operation of the pipe will cause serious consequences.
The seat sealing ring is an important component of the valve. The sealing materials include nylon and fluororubber. No matter what kind of material the sealing ring is made from, it can't avoid abrasion, erosion and damage from hard objects, which will cause inner leakage of the valve. Therefore, protecting the valve seat is the most important thing in valve maintenance.
Once the valve can't be opened or closed; the sealing device is damaged; serious inner leakage happens; the grease fitting is blocked; external leakage occurs, it is difficult to solve the problems in time when the pipe is under pressure. The problems can be solved after pressure relief, resulting in waste of manpower and material resources and environmental pollution. Thus, it is very significant to maintain the valve before it is put into operation.
