Background
In recent years, with the rapid development of the LNG industry in China, the demand of LNG low-temperature valves has also sharply increased. For a long time, these valves with high technical content and high added value have been dependent on importation, high price and long manufacturing cycle.
However, the material of the seal member becomes hard and loses its elasticity at an ultra-low temperature, so that the medium leaks from the seal member. The seal ring is a high-performance seal element with a special spring arranged in a PTFE jacket, and the seal lip is pressed against a matching metal surface by adding proper spring force and system fluid pressure to generate a very excellent sealing effect. The elastic compensation provided by the spring can overcome the defect that the material loses elasticity after hardening at ultralow temperature and the slight eccentricity of the metal matching surface. Because this sealing washer is during the installation, be interference fit between circle and valve body, the valve seat subassembly, if the installation is improper, excessive friction can seriously wear and tear the sealing washer surface between the surface of circle and the metal, makes it lose sealed effect.
