Large diameter electric fully welded ball valve
Hebei Tongli Company newly launched a large diameter electric fully welded ball valve in this year. From research and development to production, Hebei Tongli Company guarantees quality. All welded ball valves sold have a one-year warranty and a design life of one year.
Application occasions of large-diameter electric fully welded ball valve:
City gas: gas output pipeline, main line and branch line supply pipeline, 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, exhaust gas emission pipelines, gas and heat supply pipelines, and fuel supply pipelines.
Various industrial equipment: various heat treatment pipelines, various industrial gas and thermal pipelines.
Technical features of large-diameter electric fully welded ball valve:
. Large-diameter electric fully welded ball valve will not have external leakage and other phenomena. Because the valve seat is composed of carbon fiber reinforced Teflon seal and butterfly spring, so It has strong adaptability to changes in pressure and temperature, and will not cause any leakage within the marked pressure and temperature range.
. The processing of the sphere is tracked and detected by advanced computer detectors, so the processing of the sphere is highly accurate.
. 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 R material with %b (carbon) content, ensuring no leakage (%).
. Large-diameter electric fully welded ball valves can be directly buried underground according to construction requirements. There is no need to build high and large valve wells. 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 construction and design requirements.
. The processing accuracy of the sphere is very precise, the operation is light and there is no bad interference. The use of high-grade raw materials can ensure the above pressure. Compared with products of the same specification in similar industries, the valve body is small and beautiful in appearance.
. Under normal operation and use of the valve, the service life is more than one year.
Precautions for installation of large-diameter electric welded ball valve:
) Make sure that the pipeline and valve have been flushed before operation.
) The operation of the valve drives the valve stem to rotate according to the input signal size of the actuator: when rotating forward/turn (&), the valve is closed. When rotated in the opposite direction/turn (&), the valve opens.
) When the actuator direction indicator arrow is parallel to the pipeline, the valve is in the open state. When the indicator arrow is perpendicular to the pipeline, the valve is in the closed state.
