Main uses of leak-free fully welded ball valves:
&Jinke Tongli&r brand fully welded ball valve body is welded from steel pipes. The ball pad is made of reinforced polytetrafluoroethylene. The valve stem adopts explosion-proof design. Temperature range: ℃.
Fully welded ball valves are widely used in long-distance pipeline fields such as natural gas, petroleum, heating, chemical industry and thermal power pipeline networks.
The main application areas of non-leakage fully welded ball valves are:
City gas: gas output pipelines, main lines and branch line supply pipelines, etc.
Centralized heating: output pipelines, main lines, and branch lines of large-scale heating equipment.
, Heat exchanger: opening and closing of pipes and circuits.
, Steel plant: various fluid pipelines, waste gas selective discharge pipelines, gas and heat supply pipelines, and fuel supply pipelines.
Integrated welded ball valves are used in various industrial equipment: various heat treatment pipelines, various industrial gas and thermal pipelines.
The structure of the leak-free fully welded ball valve:
The ball valve body is welded by the shell assembly of five parts of seamless steel pipes for fluids. The structure is compact and the entire ball valve is integrated. At present, most of the large-diameter ball valves used in domestic production have a split three-piece structure, and each part is connected by bolts. Compared with the three-piece ball valve, the wall thickness of the fully welded ball valve forging can be made very thin under the same strength. The valve weight can be reduced by a quarter, while resistance to pipe bending and pinching is increased due to the elimination of valve body flanges and bolts. Overall dimensions reduced. Co-calling also eliminates potential leakage channels. In addition, the internal curve of the valve body welding structure is smooth. The lubricated connection with the pipeline is maintained without dead ends, and the medium fluidity is good.

Features of non-leakage fully welded ball valves:
The biggest feature of non-leakage fully welded ball valves is that there will be no external leakage.
) Since the valve seat is made of carbonized Teflon sealing rings and carbon springs, it has strong adaptability to pressure and temperature changes and will not cause any leakage within the marked pressure and temperature range.
) The processing process of the sphere is tracked and detected by advanced computer detectors, so the processing accuracy of the sphere is high.
) Since the material of the valve body is the same as that of the pipe, there will be no uneven stress and no deformation due to earthquakes and vehicles passing over the ground. The pipe is resistant to aging. The sealing ring body is made of %C (carbon) material to ensure no leakage (%).
) Directly buried welded ball valves can be buried directly underground. There is no need to build high and large valve wells. Instead, only small shallow wells need to be set up on the ground, which greatly saves construction costs and engineering time.
) The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline.
) The processing accuracy of the sphere is very precise, the operation is light and there is no adverse interference.
) uses high-grade raw materials to protect the above pressure.
) Compared with products of the same specifications in similar industries, the valve body is small and beautiful in appearance.
) As long as the valve is operated and used normally, the warranty period is one year.
