QB spherical compensator, rely mainly on the angular displacement of the sphere to absorb or compensate for one or a plurality of directions conduit lateral displacement, the compensation should be used in pairs, a single use without compensation capability, but it can be used as a universal joint pipeline. So has the ability to compensate large, fluid resistance and deformation stress is small, no blind plates and fixed bearing force is small. At the same time on this device that can inject additional packing unit of this advanced technology, making the device more stable and reliable sealing performance. Even long-running leakage, but also need to stop gas pressure maintenance and can be very convenient. Especially for long-distance transport of heat, there are significant economic and social benefits. One. Applications ball compensator is a device to solve the thermal expansion and contraction of the pipe, can be widely used in metallurgy, petroleum, chemical, power, light industry, textile, construction and defense, construction and other industries, specifically for the following purposes: 1, in heat pipes, thermal expansion compensation, the compensation capacity of 5-10 times "Jiong" compensator. 2, for the rocket launchers, aircraft exhaust facilities, the impact of the expansion of compensation. 3, evaporative cooling systems for metallurgical equipment (such as blast furnace, converter, electric furnace, furnace, etc.), and as a universal joint. 4, various pipes used in buildings, to prevent uneven ground subsidence, earthquakes and other causes of accidents or cause damage to the pipeline. II. The main technical indicators 1, Specification: QB41 / 61SA-10/16/25 / 40C 2, the working medium: steam, hot oil, hot water. 3, the working temperature: ≤350 ℃ / ≤500 ℃
