Making spool rubber bodies center form annular thin shape and seal the wing, valve core top end face center is provided with annular link slot, also
Including the circular connector that cross section is L-shaped, connector includes the connecting portion being embedded in link slot and is pressed in the pressure sealing wing edge
Real part.
This structure uses multi-sealing structure, at aspect high pressure resistant, wear-resistant advantageously, good sealing effect, uses the longevity
Life is long, and spool rubber bodies forms the first order and seals, and O-ring seals is formed multi-sealed, and utilization simultaneously seals the wing and improves sealing,
And during by sealing wing sealing, relatively thin owing to sealing the wing, it is possible to use connector is stably connected with the sealing wing, improve spool rubber
Body stability.
In above-mentioned a kind of multi-sealed plug sealing structure, described circular trough bottom land is deepened near perforation hole wall
Being provided with and add deep trouth, and compacting portion is embedded in and adds in deep trouth, connecting portion laminating perforation hole wall is arranged.
Therefore avoid connector that sealing is impacted.
In above-mentioned a kind of multi-sealed plug sealing structure, described O-ring seals and spool rubber bodies material
For nitrile rubber.
Select Oil-resistant cold-resistant nitrile rubber, adapt to operating ambient temperature up to-50 to+70 DEG C, it is to avoid close under low temperature environment
Envelope lost efficacy.
In above-mentioned a kind of multi-sealed plug sealing structure, described spool rubber bodies bonding by Vulcanization is at valve core
On.
Compared with prior art, this utility model has the advantage that
This structure uses multi-sealing structure, at aspect high pressure resistant, wear-resistant advantageously, good sealing effect, uses the longevity
Life is long, and spool rubber bodies forms the first order and seals, and O-ring seals is formed multi-sealed, and utilization simultaneously seals the wing and improves sealing,
And during by sealing wing sealing, relatively thin owing to sealing the wing, it is possible to use connector is stably connected with the sealing wing, improve spool rubber
Body stability.
