Product description of Fully Weld Ball Valve
Fully welded ball valve is a kind of welded ball valve. The valve body structure is completely welded to ensure the sealing performance of the ball valve. At the same time, it is easier to connect the full welded ball valve to the gas pipeline, and the pipeline material is used when making the full welded ball valve. Due to the same material, it is a pipe, which will not bear uneven stress or deformation when the earthquake or vehicle passes through the ground, and will not deteriorate with the passage of time. More importantly, the fully welded ball valve can be directly buried underground instead of building a large valve well, and only a small shallow well can be buried underground, thus saving construction costs and engineering time.
Features of Fully Weld Ball Valve
1. Compact structure, light weight, easy insulation and installation.
2. The all welded ball valve adopts the carbon steel seamless steel pipe pressed integral welded ball valve.
3. Carbon reinforced PTFE inclined elastic seal ring is used for sealing, and the negative pressure is on the spherical surface, so that the seal has the advantages of zero leakage and long service life.
4. The valve rod is made of AISI303 stainless steel, and the valve body is made of AISI304 stainless steel. After finishing and grinding, it has excellent sealing performance and corrosion resistance.
5. The connection mode of this ball valve: welding, thread, flange, etc. for users to choose. Transmission mode: handle, turbine, pneumatic, electric and other transmission structures are adopted, and the switch is flexible and light.
6. The integrated welded ball valve is developed by absorbing foreign advanced technology and combining with the actual situation in China. It replaces imports with domestic products and fills the domestic gap. It is widely used in the fields of long-distance transmission pipelines such as natural gas, petroleum, heat supply, chemical industry and thermal power pipe network.
Industrial applications of Fully Weld Ball Valve
The stability of Fully welded ball valve performance is beyond the scope of ordinary cast steel ball valve, and its service life is longer than that of cast steel ball valve. All welded ball valves are widely used in urban gas, urban heating, petrochemical, shipbuilding, steel, pressure regulating stations, power plants and other pipeline equipment. Fully welded ball valves basically do not need daily maintenance requirements. It mainly means that there are operational requirements for sewage and grease injection, and the following guidelines should be followed: when cleaning the pipeline, the sewage should be discharged as planned. After hydraulic test, before the cold season. When draining water, the ball valve of all welded ball valve must be in the fully closed or fully open position. Slowly loosen the drain valve spool until the pressure in the valve chamber is completely discharged, and then tighten the spool. Fully welded ball valve is a typical narrow gap submerged arc welding product, which involves material science, welding technology and automatic development of welding equipment
