Pipe seismic support - fan support and hanger - air duct support and hanger
The subdivision of spring supports and hangers can be divided into spring hangers and spring supports. It is believed that everyone is familiar with spring supports and hangers, but in what state can spring supports and hangers function?
How does it resolve such contradictions? Spring hanger is a mechanical installation designed according to the principle of moment balance. It can be used to suspend and support the pipeline and equipment. At this time, when the pipeline or equipment has displacement, it only needs to be within the pre selected load displacement.
Spring hanger is a mechanical installation designed according to the principle of moment balance. The pipeline and equipment can be suspended and supported through it. At this time, when the pipeline or equipment has displacement, it only needs to be within the pre selected load displacement. No matter how large the displacement changes, they can always obtain a constant support force through the spring support. Thus, new additional pressure will not be brought to the pipeline or equipment, so that serious equipment and safety accidents can be prevented.
In general, spring supports and hangers should be considered for important parts with large thermal displacement. Because of this characteristic of constant force spring supports and hangers, they are more and more widely used in thermal power installation of ordinary thermal power plants, nuclear power plants, petroleum and chemical industries.

The pneumatic butterfly valve is a labor-intensive industry. Cixi, the hometown of pneumatic butterfly valves, once became a gathering place of pneumatic butterfly valves by virtue of the traditional competitive advantage of low cost. The products are not only popular in major cities in China, but also exported to Europe, Africa, the Middle East and other places by virtue of the spring breeze of previous Canton Fair.
In recent years, the export tax rebate rate of pneumatic butterfly valves has declined, and money has increased rapidly, further reducing the profit margin of pneumatic butterfly valves. Secondly, the production of pneumatic butterfly valves is mainly affected by the quotation of raw materials such as steel. The instability of the steel market has also led to a great increase in the sales risk of pneumatic butterfly valves. Pneumatic butterfly valves are mostly low profit commodities, and the market competition is fierce. It is impossible to raise prices uniformly. A seller admitted that a single price increase is undoubtedly tantamount to giving up old customers. With the increasingly fierce market competition of pneumatic butterfly valves, how to adhere to the sustainable development of pneumatic butterfly valves in China has become a question many manufacturers have to face. Therefore, many manufacturers and sellers of pneumatic butterfly valves have increased their efforts to develop and sell their own brands.
Tongfeng pneumatic butterfly valve indicates that building brand influence is the best choice for the continuous expansion of pneumatic butterfly valve. Brand building, quality first. No matter how wonderful the implementation strategy is, it is based on business quality. Only when the manufacturer guarantees the quality of the goods, can he win the trust of customers. If you want to occupy a place in the market, improving quality is the key.
After nearly 20 years of development, the current Tongfeng pneumatic butterfly valve products have gradually become serialized, standardized and branded. Not only are the types standardized and complete, but also the quality of the products is stable. Some famous and high-quality products introduced have certain competitiveness in the world market. There is still a long way to go before the pneumatic butterfly valve can stand firmly in the world market. Tongfeng pneumatic butterfly valve should, based on the advantages of the original market and the stability of the traditional pneumatic butterfly valve, speed up the development of new products, improve the scientific and technological content of products, add added value, establish its own brand, and provide users with excellent products and perfect services.
