In early May, a new business was carried out in the Boiler and Pressure Vessel Test in Jincheng City, Shanxi Province. Through the grinding and calibration, unqualified safety valves on pressure-bearing equipment were brought back to life. Safety valve is to protect the boiler, pressure vessel safe operation of the important components. When the pressure inside the pressure equipment exceeds the rated pressure of the equipment by a certain value, the pressure will release the pressure through the safety valve to reduce the pressure inside the equipment and prevent the explosion of the equipment. The safety valve on the pressure cooker that people use daily has the same function as the safety valve on pressure equipment. Pressure boilers in the city, many for urban heating. Due to the seasonality of heating season, the boiler will be out of service for 8 months a year after the heating period of 4 months in the north ends. Prolonged exposure to the air, combined with summer wetness and media erosion, safety valves are often corroded. Because of corrosion, many safety valves in annual inspections were eliminated because they were judged not to meet safety requirements. Jincheng City pot inspection by the survey found that there are more than 2000 local pressure equipment, statutory inspection, more than half of each year due to rust valve safety failure needs to be replaced. Only replace the failed safety valve, is a small overhead. According to test technicians, safety valve corrosion directly affect the sealing. Because the safety valve sealing is poor, the boiler will leak during operation, causing the water temperature in the boiler to rise slowly and waste energy. More importantly, the safety valve due to corrosion blocking the sealing surface and malfunction, pressure equipment will bring security risks. Boiler pressure is higher than the rated pressure need to release energy, the safety valve can not be promptly bounced, the boiler will be unexpected serious accident. In the test, the safety valve which was judged not to meet the requirements was mainly because the surface was corroded and the sealing was poor. According to the inspection staff Jincheng pot inspection, the use of a replacement safety valve a year, a lot of waste. In order to reduce the burden on enterprises, they began to provide extended services: grinding safety valve. In order to carry out this service, they have purchased over 10,000 yuan of equipment and hired senior technicians to grind the safety valves that fail to meet the requirements, reopen the pressure test, and handle and verify the technical requirements to meet the requirements of safety specifications After they returned the safety valve to the user. The people who use the unit said that in the past, the boiler had been idle for more than six months a year, and a safety valve was to be replaced each year at a cost equivalent to two or three months' income of a fireman. Now with a little processing fee, you can continue to use it safely. The better service for your business, the better.
