Description

Technical Field

[0001] This utility model relates to the field of mechanical seal technology, specifically to a metal spiral wound gasket mounting and positioning device. Background Technology

[0002] Spiral wound gaskets, also known as inner and outer ring spiral wound gaskets, are a widely used type of sealing gasket and offer the best resilience among semi-metallic gaskets. They are made by alternately overlapping and spirally wound high-quality SUS304 or SUS316 ("V" or "W" shaped) metal strips and other alloy materials with soft materials such as graphite, asbestos, PTFE, and asbestos-free materials. The metal strips are secured at the beginning and end by spot welding. Additionally, the gasket may include inner and outer steel rings to control its maximum compression.

[0003] The main functions of spiral wound gaskets include: Sealing: Spiral wound gaskets are mainly used for sealing flange connections in pipes, valves, pressure vessels, condensers, heat exchangers, etc., ensuring a tight and secure seal. Adjusting pipe load: The excellent resilience of spiral wound gaskets allows for automatic adjustment to pressure, thermal cycles, and vibrations in piping systems. They are particularly suitable for applications with uneven loads, easily loosened joints, periodic temperature and pressure changes, and impacts or vibrations.

[0004] However, in practical applications, metal spiral wound gaskets, as important sealing elements, are widely used in flange connections of pipelines, valves, pressure vessels, and other equipment. However, during actual installation, factors such as uneven flange sealing surfaces, gasket size mismatch with the flange, and improper installation tools often lead to gasket misalignment, affecting sealing performance and even causing leakage accidents.

The drive motor 6 is equipped with a synchronous controller. The transmission shaft of the drive motor 6 passes through the outer end of the operating handle 5 and a transmission shaft column 7 is fixedly installed. The inner side of the transmission shaft column 7 is rotatably connected to both ends of the positioning device body 2 via a rotating shaft. A first synchronous pulley 8 and a second synchronous pulley 9 are fixedly installed on the outer curved surface of the transmission shaft column 7 from the inside to the outside. The outer ends of the first synchronous pulley 8 and the second synchronous pulley 9 are respectively driven by a synchronous belt to a third synchronous pulley 10 and a fourth synchronous pulley 11. A first internal thread transmission tube 12 and a second internal thread transmission tube 13 are fixedly installed in the middle of the third synchronous pulley 10 and the fourth synchronous pulley 11, respectively. The first internal thread transmission tube 12 and the second internal thread transmission tube 13 are respectively rotatably connected to both sides of the positioning device body 2 through a rotating shaft. The inner walls of the first internal thread transmission tube 12 and the second internal thread transmission tube 13 are respectively threaded with transmission screws 14. An arc-shaped extrusion plate 15 for extruding and positioning the metal spiral wound pad is fixedly installed on the inner side of the transmission screw 14.
