mxq series rotary joint is new and seal-adjustable designed for hot-oil, steam transfer user. It is widely used in industries such as rubber and plastic, leather, textile, machinery etc. To transport high-temperature medium. 1\ Use the shell of no.500 ductile cast iron and monolithic spherical pig, the ball surface is carefully lapping and processed. 2\ Spring is made of spring steel of tungsten-chromium-vanadium alloy to ensure the sealing surface the sealing surface to fit closely. 3\ High-temperature seal components immersed in liquid silver and plumbago, seal components immersed in stibonium. 4\ Use ffkm o-ring which has over-all properties of heat resistance and corrosion resistance etc. To achieve block and seal between inner and external pipes 5\high temperature, high speed, high pressure design, is available for hot oil and steam conducting with stable, long lasting operating life. operating parameter: medium: hot oil, steam temperature:350 rotating speed:300rpm pressure:2.0mpa
