The quality of rubber soft connection Shanghai Dongfeng Valve Co., Ltd. is a professional manufacturer of electric ball valves. The electric ball valves are also called electric ball valves, valve elastic joints, pipeline shock absorbers, shock absorbers, soft joints, shock absorbers, etc. It is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The electric ball valve has single ball valve soft joint, double ball valve soft joint and reducing valve soft joint. The electric ball valve products of Dongfeng Pipeline Equipment Co., Ltd. have been praised by the majority of users since they came into the market. The electric ball valve produced by Dongfeng Pipeline Equipment Co., Ltd. has high elasticity, high air tightness, acid resistance, alkali resistance and corrosion resistance, It can withstand high pressure and has good elastic deformation effect. It is applicable to a variety of complex geological conditions and is widely used in pipeline systems in urban water supply, environmental protection, chemical industry and other industries.
The technician of Dongfeng Pipeline Equipment Co., Ltd. will tell you how to distinguish high-quality electric ball valves from unqualified products in appearance. First, from the appearance, the electric ball valves mainly include the valve ball part and the flange part. The flanges generally include forged flanges and cast iron flanges. The performance of forged flanges is better than that of cast iron flanges, but the price is more expensive, This is the distinction of flange material. The flange shape is distinguished from the national standard flange, which must have the specified outer circle and thickness. The flange of general unqualified products will have problems on the outer circle and thickness, and the non-standard ones will be relatively small, which is not very safe in the use process. Later, the electric ball valve with cast steel flange is easy to rust, and the flange will rust and fall off when non-standard products are generally used, In this way, the screw hole will burst, affecting the safe use.
In terms of the valve ball, it is mainly the valve material and the thickness of the valve ball. Good valve material has corrosion resistance and is expensive. The general electric ball valve 1.6MPa needs 16 layers of valve thickness for vulcanization, and the unqualified electric ball valve is generally about 10 layers. The arch part of the electric ball valve made in this way is relatively soft and has poor use effect, The electric ball valve is soft and flexible so as to meet the use requirements. Our electric ball valve is equipped with a steel wire protection device, which can withstand greater pressure during use. Compared with the products of ordinary manufacturers, the performance of the electric ball valve is more outstanding. Shanghai Dongfeng Valve Co., Ltd. has more than 20 years of manufacturing experience. From the production of electric ball valves to finished products, it has strict quality control. In addition, for each special electric ball valve, it uses special valves to make it. It has unique experience and plans both in the selection of raw materials and in the manufacturing process of electric ball valves, The quality of each electric ball valve is guaranteed. As an entity manufacturer specializing in producing electric ball valves for many years, Shanghai Dongfeng Valve Co., Ltd. can process a wide variety of electric ball valves. Welcome to purchase.
