Description
Technical field
The utility model relates to the sealing device of a kind of rubber-metal compound film sheet for valve system.
Background technology
At present, end face seal typically uses O circle to seal, and O encloses sealing effectiveness difference, and service life is short, high temperature high voltage resistant
Difference, uses fragile.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rubber-gold for valve system reasonable in design
Belong to the sealing device of compound film sheet.
For solving the problems referred to above, technical solution adopted in the utility model is:
The sealing device of a kind of rubber-metal compound film sheet for valve system, including be arranged under adpting flange
End face seal groove between end face and lower adpting flange upper surface and the sealing ring being arranged in end face seal groove；Skeleton ring
External diameter is more than the external diameter of sealing rubber ring, and the internal diameter of skeleton ring is less than the internal diameter of sealing rubber ring；Described sealing ring includes skeleton
Circle and two sealing rubber rings being symmetricly set on the upper and lower both ends of the surface of skeleton ring；The madial wall of sealing rubber ring is provided with
C-opening；The upper and lower end face of skeleton ring is respectively arranged with the chimeric bayonet socket of setting-in sealing rubber ring；Sealing rubber ring is used for sealing
End face be inner conical surface.
Further, described end face seal groove is loop configuration.
Further, described skeleton ring and sealing rubber ring sulfuration is arranged.
Further, described skeleton ring sharp edge is blunt.
Further, described skeleton ring is spring steel.
Use and have the beneficial effects that produced by technique scheme:
The utility model uses skeleton ring both sides sulfuration caulking gum coil structures, good airproof performance, the good rigidly of sealing ring, makes
Use the life-span long, good toughness；Skeleton ring is wider than sealing rubber ring, thus when preventing assembling adpting flange with lower adpting flange, damages
Hinder sealing rubber ring, reasonable in design, good manufacturability；Improved the bearing capacity of sealing ring by c-opening, inner conical surface is arranged, and makes
When obtaining the deformation of sealing rubber ring sealing surface, uniform-compression,
The utility model compact conformation, reasonable in design, with low cost, good manufacturability.
Brief description
Fig. 1 is structural representation of the present utility model.
Wherein: the 1st, upper adpting flange；2nd, lower adpting flange；3rd, end face seal groove；4th, skeleton ring；5th, sealing rubber ring；6、C
Type opening；7th, it is fitted together to bayonet socket.
Detailed description of the invention
As it is shown in figure 1, the sealing device of the rubber-metal compound film sheet for valve system of the present embodiment, including set
Put the end face seal groove 3 between upper adpting flange 1 lower surface and lower adpting flange 2 upper surface and be arranged on end face seal groove
Sealing ring in 3；Sealing ring includes skeleton ring 4 and two sealing rubber rings being symmetricly set on skeleton ring both ends of the surface about 4
5；The madial wall of sealing rubber ring 5 is provided with c-opening 6；The upper and lower end face of skeleton ring 4 is respectively arranged with setting-in and seals rubber
The chimeric bayonet socket 7 of cushion rubber 5；The external diameter of skeleton ring 4 is less than caulking gum more than the external diameter of sealing rubber ring 5, the internal diameter of skeleton ring 4
The internal diameter of circle 5；Sealing rubber ring 5 is inner conical surface for the end face sealing.
Further, end face seal groove 3 is loop configuration, and skeleton ring 4 is arranged with sealing rubber ring 5 sulfuration, skeleton ring 4 sharp edge
Blunt, good manufacturability, skeleton ring 4 is spring steel, good springiness, good rigidly.
The utility model employing skeleton ring 4 both sides sulfuration sealing rubber ring 5 structure, good airproof performance, the good rigidly of sealing ring,
Service life is long, good toughness；Skeleton ring 4 is wider than sealing rubber ring 5, thus prevents from assembling adpting flange 1 and lower adpting flange 2
When, damage sealing rubber ring 5, reasonable in design, good manufacturability；Improved the bearing capacity of sealing ring, inner conical surface by c-opening 6
Arrange so that when the deformation of sealing rubber ring 5 sealing surface, uniform-compression,
The utility model compact conformation, reasonable in design, with low cost, good manufacturability.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；
Although the utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that:
It still can the technical scheme described in previous embodiment be modified, or is equal to wherein portion of techniques feature
Replace；It is combined being apparent to multiple technical schemes of the present utility model as those skilled in the art.And these
Modification or replacement, do not make the essence of appropriate technical solution depart from spirit and the model of the utility model embodiment technical scheme
Enclose.
