Check valve flat washer, what is the role of square washer + 15 years of flat washer manufacturer's solid fastening

The hardware responsible for the production of flat gaskets for check valves said that there are too many types of gaskets. We generally contact flat gaskets. Flat gaskets are a commonly used type of gasket, and square gaskets are also a type of flat gaskets. . Basically, flat washers can be used in general bolts or screw connections. The shape of flat washers is generally round, but according to the needs of assembly, it can also be in other shapes, such as square washers with a square shape. The following Xiaoshuo takes everyone to see the function of the square washer: 　　 1. Expand the contact surface, reduce the stress concentration of the fastening force on the fastener, and prevent damage to the fastener.　　2. When tightening the nut, the fastener will not be scratched.　　3. Flower pads and spring pads also prevent the nut from loosening. Because of the above properties of the square washer, it can effectively prevent water leakage and water seepage of the building structure, play a shock absorption and buffer effect, and also have a good fastening and sealing effect, so it is still widely used in life. The square gasket is now large Part of it is used on construction sites. Hardware, 15 years of focusing on check valve flat washers, 5,000 square meters production workshop, hundreds of precision processing production equipment, 20,000+ sets of flat washer mold custom production experience, more than 20 Ru0026D and design engineers, flat washers stamping accuracy can reach 0.01mm, The precision of flat washers can reach 0.01mm, and 16 quality inspections strictly control the quality from raw materials layer by layer.
