Description
Technical Field
The utility model belongs to the pipe connection seal structure field, more specifically say, relate to a contact seal structure.
Background
Mechanical sealing mechanisms are used extensively in pipelines of power plants. In the conventional mechanical sealing device, the sealing end face is generally formed by directly contacting the static ring and the dynamic ring. The direct contact mode ensures that a lubricating oil film between the static ring and the moving ring is very thin and is usually only a few microns thick, so dry friction is easily formed between the moving ring and the static ring, and the abrasion of the joint surface of the moving ring and the static ring is easily caused. As the friction time between the static ring and the moving ring is prolonged, after the temperature rises, the surface of the static ring and the surface of the moving ring are adhered, the friction factor is increased, and larger friction heat is caused, so that the metal adhesion between the two surfaces is more serious, and the friction factor is further increased.
The current technology is to use different materials for the moving ring and the static ring, such as ceramic material and metal material to match. Because the ceramic material is inconvenient to process, the surface roughness of the manufactured ceramic material is large, the friction factor is large, and the friction heat between the dynamic ring and the static ring is high; and the metal material is easily worn out and needs to be replaced frequently.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a not enough to prior art exists, the utility model aims to provide a contact seal structure, reasonable in design adopts the lubrication groove and can save the lubricating oil buffering part of lubricating oil and mutually support, can realize good lubrication action between body and rotating ring, reduces friction, wearing and tearing, the medium leakage between body and the rotating ring greatly, improves the life of rotating ring, also guarantees good mechanical seal performance between these two terminal surfaces.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a contact seal structure characterized in that: comprises a movable ring part sleeved on a pipe body and a static ring part sleeved on an adjacent pipe body; the static ring part comprises a static ring and a first extension ring body fixedly connected to the outer side surface of the static ring, and a plurality of annular bulges are arranged on the inner side surface of the static ring; the static ring is fixedly connected with the pipe body; the movable ring part comprises a movable ring and a second extension ring body fixedly connected to the outer side surface of the movable ring, annular grooves which correspond to the annular bulges one by one are formed in the inner side surface of the movable ring, and the annular bulges are clamped in the annular grooves to realize sliding connection; the inner side part of the moving ring is symmetrically provided with two lubricating grooves, the upper ends of the lubricating grooves are communicated with a lubricating oil buffering part, the lubricating oil buffering part is communicated with an oil inlet, and the oil inlet is provided with a plug for sealing.
As an optimized technical scheme, a first O-shaped rubber ring is arranged between the first extension ring body and the pipe body.
As an optimized technical scheme, a second O-shaped rubber ring is arranged between the second extension ring body and the pipe body.
As an optimized technical scheme, the lubricating oil buffering part comprises a buffering channel communicated between the lubricating groove and the oil inlet, a plurality of transition channels parallel to the lubricating groove are communicated and arranged on two sides of the buffering channel, each transition channel is plugged at one end, and the other end of each transition channel is communicated with the buffering channel. Excessive passageway can effectively reduce the oil pressure of lubricating oil to body position department, reduces the use amount of lubricating oil, also can reduce the risk of oil leak to a certain extent.
As an optimized technical scheme, the number of the transition channels is 2-5 pairs.
