PTFE rubber seal is a seal made of polytetrafluoroethylene (PTFE). PTFE is a synthetic material with excellent chemical stability and low friction properties that is used in a wide range of industrial fields.
PTFE spring energized seals are an important sealing component widely used in hydraulic and pneumatic systems. It is made of polytetrafluoroethylene (PTFE) and achieves a high-performance sealing effect through the design of a spring energy storage structure.
PTFE Filled Glass Fiber O-Rings are high-performance sealing elements that are reinforced with polytetrafluoroethylene (PTFE) matrix material filled with glass fibers. This composite material combines the excellent properties of PTFE with the reinforcement effects of glass fiber to provide higher compressive strength, lower coefficient of thermal expansion and improved wear resistance.
Los sellos mecánicos rotativos de resorte tienen las características de estructura simple, el consumo de aire comprimido es grande, y la presión de la fuente de aire es 0,03-0,05 mpa mayor que la del medio de sellado. La función del dispositivo de carga por muelle es producir una fuerza de presión, mantener la cara extrema de los anillos móvil y estático en estrecho contacto, y es un elemento amortiguador, que puede compensar la superficie de fricción que no encaja causada por la excentricidad del eje y el error de procesamiento.

PTFE and O-ring seals are a common sealing solution, providing reliable performance and elasticity. PTFE has excellent chemical stability and low friction coefficient, but its plasticity makes it difficult to form an effective seal. O-ring seals, with their good elasticity and compression deformation, fill the gap between PTFE and the sealing surface, preventing liquid or gas leakage. Both seals have low friction, high temperature resistance, and are easy to install, making them suitable for various applications like pipe connections, valves, pumps, and pressure vessels.
Los anillos Glyd rellenos de PTFE y fibra de carbono para cilindros son un elemento de estanquidad de alto rendimiento diseñado para aplicaciones de estanquidad dinámicas, como los cilindros. Estas juntas combinan las excelentes propiedades del politetrafluoroetileno (PTFE) con el refuerzo de la fibra de carbono para ofrecer una mayor resistencia al desgaste, un menor coeficiente de fricción y una mejor estabilidad térmica.
Las juntas de los brazos robóticos tienen ciertos requisitos de presión y requieren que la superficie de la junta tenga un acabado determinado. Los componentes de sellado son en su mayoría de caucho, y el efecto de sellado se consigue mediante la deformación local de las juntas. Su rendimiento de estanquidad y su vida útil dependen de muchos factores, como la selección, la precisión de la máquina, su correcta instalación y su uso.
PTFE sealing rings are crucial in chemical butterfly valves, providing reliable sealing performance, corrosion resistance, and temperature adaptability. They are used in stem seals to prevent medium leakage, seat seals to prevent media leakage, and leak control in applications requiring strict seals. PTFE rings also offer temperature adaptability, ensuring their performance remains stable at different temperatures, making them suitable for various working conditions in chemical butterfly valves. Overall, PTFE sealing rings are essential for the safe operation of butterfly valves and media control in chemical processes.
Las juntas de varilla de fibra de vidrio rellenas de PTFE son elementos de estanquidad de alto rendimiento que combinan las excelentes propiedades del politetrafluoroetileno (PTFE) con el refuerzo de la fibra de vidrio. Este compuesto proporciona una mayor resistencia al desgaste, un menor coeficiente de fricción y una mayor estabilidad térmica. Adecuado para una gran variedad de aplicaciones industriales duras.
La válvula de sellado de diafragma no necesita una estructura de sellado de empaquetadura de vástago separada, el diafragma corta el medio al mismo tiempo para sellar el vástago de la válvula. Y el diafragma flexible es fiable para cerrar, e incluso el líquido sucio se puede cortar bien. Por lo tanto, el mecanismo de control y el canal de medios están completamente separados, de modo que la válvula de diafragma no sólo puede aplicarse a la industria alimentaria y la industria médica y sanitaria, sino también para algunos medios difíciles de transportar y medios peligrosos.
