Details determine success or failure, and small products often have large markets. As an indispensable safety device for all kinds of pressure equipment, safety valve is a "reassuring pill" to ensure the safe application of its products. It is widely used in industrial production fields such as boilers, pressure vessels, pressure pipelines, petrochemicals, and nuclear power. In recent years, with the further development of the trend of economic globalization, all industries in China are also driven by the general environment, the technology is changing with each passing day, and the safety valve industry is also constantly innovating, producing a wide variety of products with more advanced technology and higher quality standards. series of products to continuously meet market demand.

As a special equipment industry, there are currently not many manufacturers qualified to produce safety valves in my country. As a leader in this industry, Shanghai Wuyue Pump and Valve Group, guided by technology, continuously strengthens its independent innovation capabilities, breaks through technical bottlenecks, and has developed a variety of Safety valve series products suitable for applications in various industries, including spring-type safety valves, pilot-operated safety valves, safety valve quick switching devices (quick switching safety valves), high temperature and high pressure safety valves, power station safety valves, fluorine-lined safety valves, etc. Products occupy a pivotal position in the industry.

Taking the spring-type safety valve newly developed by Shanghai Wuyue Pump and Valve Group for boiler application as an example, its main features are as follows:

The product consists of valve core, valve seat, valve stem, spring, adjusting screw, etc. It mainly uses the spring force to press the valve core on the valve seat. When the boiler pressure exceeds the pressure acting on the upper part of the valve core by the spring, the valve core and the valve stem are lifted up, and the steam is discharged; when the boiler pressure is lower than the pressure acting on the upper part of the valve core by the spring, the valve core is depressed on the valve seat, The boiler stops exhausting steam. The design greatly improves the safety of the boiler, and can avoid the occurrence of dangerous events to the greatest extent by reminding in advance.

Secondly, when the steam lifts the valve core, the edge of the valve core is also affected by the steam pressure, so that the entire working area suddenly increases, and the safety valve opens immediately; when the lowering force is reduced, due to the sudden reduction of the steam force, the valve core is once closed to prevent the spool from beating repeatedly. The design reduces the wear and tear of the safety valve during use and increases its service life.

The spring-type safety valve has compact structure, light size, good tightness, easy adjustment and vibration resistance. It is one of the most commonly used products in large and medium-sized industrial boiler rooms. It is also the company's innovation-driven development strategy and continuous exploration of new technologies , a new way, and striving to move towards a microcosm on the road of transformation and upgrading.

According to the person in charge of the research and development department of Shanghai Wuyue Pump and Valve Group, its products can also be "customized" according to customer needs to meet the needs of different customers. It is worth mentioning that the safety valve products can still be designed according to the national standard, American standard, German standard, British standard and Japanese standard, which has laid a good foundation for its products to go abroad and go overseas, and achieved good market benefits.
