Due to the performance and reliability of the safety valve is directly related to the safety and stable operation of the device, it is necessary to strictly implement the relevant standards such as API, ASME standards Weifang A38Y-16C safety valve in the design, material selection, manufacturing, testing, etc., and the whole process of strict quality management. In order to meet the domestic industry and foreign standards for safety valves have advanced level of requirements, from eight years beginning Weifang double spring safety valve, after the successful development of the common safety valve valve manufacturer, has developed a pilot valve and Switching safety valve. Broadly speaking, including the so-called safety valve relief valve, from a management point of view, rule, mounted directly on a steam boiler or pressure vessel, which is a necessary condition must be approved valve technology supervision department, called the safety valve on the narrow, Other commonly known as the bleed valve. Safety valves and relief valves are similar in structure and properties, both of which are more than the automatic discharge opening pressure inside the medium, in order to ensure plant safety. Because of this similarity is essentially the safety valve, when people use, often confuse the two. In addition, some production facilities in the rules which can be also provided. Therefore, the difference between the two is often overlooked. Everbright valve model (Figure) _ _ Double spring safety valve safety valve provided by Shandong China Everbright Limited valve.
