A chain link Fence is a type of fence made up of interlocking metal wires that form a diamond-shaped pattern. It is commonly used for various purposes, such as securing residential or commercial properties, creating boundaries for sports fields, or enclosing outdoor spaces.
The main components of a chain link fence include the metal posts, top rail, tension wire, and the chain link fabric itself. The posts are typically made of steel and are installed at regular intervals along the fence line. The top rail runs horizontally along the top of the fence, providing additional stability and support.
The chain link fabric consists of woven metal wires that form the diamond-shaped pattern. It is available in different heights and gauges, with smaller gauges being thicker and more durable. The fabric is attached to the posts and top rail using tension bands, which are secured with bolts or screws.
To enhance the security of a chain link fence, additional features can be added, such as Barbed Wire or privacy slats. Barbed wire is typically installed at the top of the fence to deter climbing or trespassing, while privacy slats can be inserted into the chain link fabric to block the view from outside.
Chain link fences are popular due to their affordability, durability, and low maintenance requirements. They provide a secure barrier while still allowing visibility and airflow. Additionally, they can be easily customized with various colors and coatings to match the surrounding environment.
Overall, chain link fences are versatile and widely used for both residential and commercial purposes, providing a cost-effective and practical solution for securing and defining outdoor spaces.

Yuan water-cooled air respirator pump won the national patent (Figure)
As early as November 9, 2010, Zhejiang Yu An Fire Equipment Co., Ltd. invested in research and development, with complete independent intellectual property rights of "water-cooled air respirator filling pump" initial success of the test machine. The cylinder temperature can be controlled within 40 degrees after 2 hours of continuous filling. The successful development of this technology equipment marks that Yu'an Fire has mastered the key technologies of producing ultra-high pressure filling compression equipment and has stepped into the world-class technology in the field and has successfully solved the technical problem of cylinder cooling of the ultra-high pressure air pump, Improve the service life of ultra-high pressure compression equipment for the mass production of the water-cooled air respirator filling pump provides a reliable, fully based. Recently, Zhejiang Yu An Fire Equipment Co., Ltd. came good news, the company invested 7.5 million yuan research and development of water-cooled air respirator filling pump project to complete trial production and mass production, the first batch of 8 215 liters of 30MPa water-cooled filling pump Products have been put into operation in Hubei Province, eight fire brigade on duty, the advanced equipment put into use for the eight detachment added new battle weapon. The project from March 2010 in the business project, through technical research, product demonstration and a series of supporting equipment integration, the enterprise in a short period of one year successfully launched the high-tech products. In the mass production of new products at the same time came good news, the water-cooled filling pump patented technology access to the State Intellectual Property Office of the patent certificate for the product of technological innovation in the law also provides a reliable guarantee and basis, Also greatly encouraged the confidence of business development. However, at present, the products produced and used at home and abroad are unable to guarantee the continuous and uninterrupted working requirements. Due to the design flaws of the compression cylinder, this greatly increases the production cost and restricts the rapid development in this field. Such as due to some special occasions need continuous use of existing technology of this type of equipment will not be completed, such as continuous use will occur due to compression cylinder can not be effectively and sufficiently heat caused by the filling pump compression cylinder part of the serious damage scrapping, Forcing the suspension of work will be endangering human life and safety. As the cooling method is mainly fan, radiator and other devices, it is well known that high-pressure filling pump is the use of mechanical principles of the gas volume is compressed to a certain percentage for use in the gas compression process due to the sudden reduction of gas volume coupled with machinery The principle of friction and thus generate a lot of heat, the gas can be rapidly compressed after the expansion of the thermal expansion and contraction of the gas to increase the friction increased so that the equipment can not play the best effect, due to the accumulation of heat can not be fully effective Release makes the machine can not work continuously, resulting in air respirator filling pump can not work, poor reliability. In addition, due to the large heat cylinder will not be immediately cooled, will result in high compressed gas temperature, but can not be used continuously. Water-cooled Ventilator Filling Pump The patented water-cooled cylinder block of this product ensures a high degree of heat dissipation and ensures that the temperature of the compressed cylinder remains within 65 degrees. This greatly reduces the risk of the cylinder being heated by the cylinder overheating , While the water-cooled filling pump for continuous 24-hour non-stop filling, to bring you a new technology to enjoy. The advantages of water-cooled filling pump: Water-cooled filling pump with water tank in the tank, equipped with water tank, cooling fan, cooling water through the pressure pump to circulate water cooling. Its advantages are five; First, the use of water-cooled cylinder technology has excellent cooling performance, not affected by the ambient temperature, can effectively avoid the danger posed by high temperatures. Water-cooled filling pump to ensure that the cylinder and the compressed gas to maintain the temperature range of 40 degrees, suitable for a long time continuous use. Reached a turning point with the human operation of the purpose. Second, due to the cylinder body, the air is always maintained at room temperature, will not lead to creep cylinder material can significantly increase the filling pump and filling the safety factor and the life of the container. Third, the water-cooled filling pump compressed gas temperature is always maintained slightly higher than normal temperature, so no need to repeat filling, gas cylinder can be a one-time filling to 30Mpa pressure and reach the corresponding product targets. Fourth, the water-cooled filling can effectively protect the cylinder and filling pump normal continuous use, making it safer and more convenient to use. Zhejiang Yuan Fire Equipment Co., Ltd. R & D and production of water-cooled filling pump, the technology is more sophisticated advanced, superior performance, can significantly reduce costs and improve product efficiency.
