The conventional products of Dongfeng brand electric ball valves are made of natural valves and nitrile valves, without reclaimed rubber. The rubber content is 46%, 46% of which consists of natural valves and nitrile rubber, and the other 54% are auxiliary materials. Ordinary products can be resistant to ordinary acid-base media. Strong acid-base uses EPDM with excellent stability and safety. The skeleton cord is nylon cord, and the number of layers is strictly in accordance with the national standards. The steel wire at the two ends of the product is thickened aviation steel wire, and the steel wire joints are brazed. The reasonable valve formula makes the product soft and hard. These details make the product pressurized, vibration damping, tensile, and more resistant to the reasonable displacement of the pipeline and the reasonable vibration of the water pump.
The main materials of ordinary valve products are recycled rubber and natural rubber, with a rubber content of about 37%, 37% of which is recycled rubber and natural rubber, 63% of which is auxiliary materials. A ton of rubber is filled with a little natural rubber, especially EPDM joints. A ton of rubber is filled with a little EPDM, which is called EPDM joints. Under strong acid and strong alkali conditions, the product life is extremely short and the safety hazard is large. The skeleton cord is made of cheap polyester cord, and the number of layers comes with the price. The two ends of the product are made of ordinary steel wire, some are brazed, some are hand made, the valve formula is unreasonable, some manufacturers' products are ultra-thin, some manufacturers' products are ultra-thick, ultra-thin, easy to burst or pull off, the ultra-thick shock absorption performance is poor, not easy to vulcanize, and the pipeline does not absorb vibration or is easy to pull off when it is vibrated or displaced, No matter how thick the product is made, it is useless if the material and technology are not good.
4、 Technicians and technical Dongfeng electric ball valve technicians are invited from domestic manufacturers of electric ball valves, and Japanese technology is introduced on the basis of domestic technology. At present, the products can be compared with domestic and foreign products. Other ordinary electric ball valves have no professional and technical personnel, and their technical starting point is low. They do not know about domestic and foreign technologies, nor do they introduce them. The products are relatively backward as a whole.
5、 The test pressure and bursting pressure of Huanxin brand electric ball valve 16KG is 1.5 times of the ex factory pressure test, i.e. 24KG, and the destructive pressure test is 3 times of the national standard. Our product can reach 5 times, i.e. 80KG. In particular, the air pressure test guarantees no water seepage and good stability.
