City Gas: gas export pipelines, the main trunk and the branch supply pipe. Central Heating: Large-scale heating equipment export pipeline, the main trunk and feeder lines. Heat exchangers: Pipeline and the loop open and close. Steel plant: a variety of liquid pipelines, gas pipelines optional release, gas and heat supply pipelines, fuel supply pipelines. All kinds of industrial equipment: all kinds of heat pipes, all kinds of industrial gas and heating pipes. Features: 1)Integrated welded ball valve, there will be no external leakage and so on. As the seat is carbonized coffee springs Teflon seal ring and the composition, so the changes in pressure and temperature adaptability, in marked pressure and temperature range will not produce any vent slip. 2)Processing sphere detector with advanced computer tracking and detection, so the sphere of processing and high accuracy. 3)As the body material with piping materials, as the stress does not appear uneven, it will not because of the earthquake and the vehicle passes through the ground from time to time deformation, anti-aging pipelines. 4)Seal ring body with content of 20% C (carbon) and PTFE material, will guarantee full no leakage (0%). 5)Buried welding ball valve can be directly buried in the ground, do not build a high large-scale valve well, simply on the ground set up a small shallow wells, considerable savings in construction costs and engineering time. 6)According to pipeline construction and design requirements, adjust the valve stem length and height. 7)Sphere is very precise machining precision, easy operation, no negative interference. Use of advanced materials, can protect more than PN25 pressure. With the same industry compared to the same kinds of specifications, valve small and beautiful appearance. 8)In ensuring the normal operation of the valve, use cases, the warranty for 20 years. Buried underground valve construction drawings Modern city inside the vehicle and pedestrian access-intensive, road conditions are extremely complicated. 9)Therefore, the construction and maintenance of gas supply pipes and heating supply pipeline construction time and construction time of its security requirements is very high. The all-welded ball valve, you can direct persistent deep underground. Method of construction using the latest engineering technology to maximize the reduction of valve control share space and greatly reduce construction costs and engineering time. But also can prevent the risk of gas explosion, all welded ball valves are very safe. 10) Buried valve drive, the operators do not need to enter the underground, just on the ground to drive operations can be very safe and convenient.
