Description

Prevent leaking gas pipeline rubber circle

Technical Field

The invention belongs to the technical field of pipeline sealing, and particularly relates to a leakage-proof gas pipeline rubber ring.

Background

The gasket is a material made of paper, rubber or copper sheet, placed between two planes to enhance sealing, and a sealing element disposed between the static sealing surfaces to prevent fluid leakage.

Gaskets are mechanical seals between two objects, typically to prevent pressure, corrosion, and natural thermal expansion and contraction leakage of the tubing between the two objects. Since the machined surface may not be perfect, the irregularities can be filled using shims. The gasket is typically made of a sheet material such as paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or a plastic polymer (e.g., polytetrafluoroethylene). The gaskets for a particular application may contain asbestos. Washers (washers) are one hole (usually in the middle) of a thin plate (usually circular) and are typically load thread fasteners for distribution. Other uses are as spacers, springs (bellville washers, wave washers), wear pads, pre-displays, lock devices. Rubber gaskets are also used in faucets (valves) to shut off flowing liquids or gases. Rubber or silicon gaskets may also be used to reduce fan vibration. Typically the outside diameter of the gasket is about twice the inside diameter.

Common rubber circle that is used for gas pipeline in the existing market is exactly one kind that belongs to the packing ring, its effect is used for the clearance department between the sealed pipeline more, play sealed, increase frictional force and buffering's effect, and common rubber circle is the annular packing ring of a rubber material in the existing market, it is not unusual oscilaltion with being connected between the pipeline, only come to make between packing ring and the pipeline contact through mutual pressure between the two, reach sealed effect with this, but if there is unevenness's place on the pipeline, the leakproofness of rubber circle will greatly reduced.
