Description

Tetrafluoro full cladding O type sealing washer appurtenance Technical Field The utility model belongs to the technical field of sealing ring installation tools, and particularly relates to a tetrafluoro full-cladding O-shaped sealing ring auxiliary tool. Background The tetrafluoro-fully-coated O-ring is usually composed of an inner elastomer (e.g. rubber) and an outer fully-coated Polytetrafluoroethylene (PTFE) layer, combining the characteristics of elasticity and chemical and high temperature resistance. In the installation process, the PTFE layer is harder, so that friction is reduced by matching with a lubricant, uniform force application is ensured, and scratch is avoided. The traditional installation auxiliary tool for the tetrafluoro full-cladding O-shaped sealing ring comprises a conical guide sleeve, a mouth expander and a hydraulic/pneumatic press, wherein the hydraulic/pneumatic press is used for automatic installation of a high-pressure scene and is required to be matched with a custom-made die for use, the cost is high, and when the conical guide sleeve and the mouth expander smoothly guide the sealing ring into a groove, the uniform thrust applied to the sealing ring cannot be ensured, the sealing ring is easy to twist, and the sealing performance is reduced.
