Description

Technical Field

[0001] The utility model relates to the technical field of sealing elements, in particular to an anti-collision type plug rubber ring pad. Background Art

[0002] The rubber gasket is made of rubber as raw material. It is a thin rubber product that acts as a seal between two stationary surfaces of metal flanges or other connecting parts. It can be manufactured by molding or punching vulcanized rubber sheets. It can be widely used in various mechanical equipment to play the role of gasket, seal, buffer, etc.

[0003] A fire hydrant is a fixed firefighting tool, which is mainly used to control combustibles, isolate combustibles, and eliminate fire sources. Fire hydrants are mainly used for fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network to implement fire extinguishing. They can also be directly connected to water hoses and water guns to discharge water for fire extinguishing. They are one of the important firefighting facilities for fighting fires. However, since fire hydrants are often located on the side of the road or in wall aisles, they are often easily collided with passing external objects, causing the sealing gasket and the valve disc head to separate, resulting in the stability and sealing of the rubber gasket and the valve disc head being greatly reduced, thereby causing the fire hydrant to leak.
