Abstract

The utility model discloses a sealing ring, which comprises a rubber ring body and is characterized in that a polytetrafluoroethylene coating is arranged outside the rubber ring body. The sealing ring has the advantages that the polytetrafluoroethylene coating is arranged outside the rubber ring body to form a composite structure, the rubber ring body made of silicon rubber has a sealing effect, the polytetrafluoroethylene coating has a lubricating effect and can resist corrosion of a solvent, elasticity of the silicon rubber and lubricating and corrosion resisting performances of the polytetrafluoroethylen are effectively combined, and a chemical performance and an application range of the sealing ring are greatly optimized.

Description

A kind of seal ring
Technical field
The utility model relates to a kind of seal ring, relates in particular to the lubricated corrosion resistant seal ring of the height of using on a kind of valve.
Background technique
Valve is mainly used in the medium that blocks or connect in the pipeline; Also can be used for the adjusting and the control of fluid; Wherein seal firmly between the metal seat valve of its V-type ball core of V-type ball valve and pile-up welding hard alloy and have very strong shearing force, be specially adapted to media such as fibre-bearing, small solid particle.The sealing of valve is a vital index, and except the structure and weld seam sealing of valve itself, the seal ring performance of using on the valve is also very crucial.Seal ring on the valve also needs high lubricated and corrosion resistance except needing good sealing property, and the ordinary silicon rubber seal is difficult to reach.
Employed seal ring is a teflin ring on the existing valve, the stable chemical performance of teflon, and corrosion resistance is strong, and good lubricity is also arranged simultaneously.Do not have rebound elasticity but the mechanical property of teflon is tough and tensile, its sealability is unsatisfactory.
Summary of the invention
The utility model provides a high lubrication and seal circle to the problems referred to above, and the sealing circle is used for valve, has high lubricated and corrosion resistance, and its elastic performance also improves greatly.
The utility model adopts following technological scheme to realize: a kind of seal ring, comprise the cushion rubber body, and it is characterized in that said cushion rubber body is outside equipped with the teflon clad.
Preferably, the material of said cushion rubber body is a silicone rubber.
Preferably, the sectional shape of said cushion rubber body is irregularly shaped, semicircle, circle or rectangle.
The beneficial effect of the utility model is; In the outside of cushion rubber body the teflon clad is set; Form composite structure, the cushion rubber body of silicone rubber material is used for sealing, and the teflon clad has been used for lubricating, solvent-proof corrosivity; Effectively combined the elasticity of silicone rubber and lubricity, the corrosion resistance of teflon, its chemical property and Applicable scope are optimized greatly.

Drawing reference numeral explanation: 1 seal ring; 2 cushion rubber bodies; 3 clads.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Like Fig. 1-shown in Figure 6; The utility model is a kind of seal ring 1, comprises cushion rubber body 2, and said cushion rubber body is outside equipped with teflon clad 3; The material of said cushion rubber body is a silicone rubber, and the sectional shape of said cushion rubber body is irregularly shaped, semicircle, circle or rectangle.The improvements of the utility model are to be outside equipped with teflon clad 3 at cushion rubber body 2, make seal ring 1 become composite structure.
The concrete making method of teflon clad 3:
Step 1, teflon is made into the film that thickness is 0.1mm;
Step 2, with the wherein one side of film through row curedization processing, make its surface have compatibility, be prone to silicone rubber bonding;
Step 3, film and silicone rubber is bonding, together sulfidization molding makes surface both firmly bonding;
Step 4, with the deburring of moulding cutter.
The utility model is provided with the teflon clad in the outside of cushion rubber body; Form composite structure; The cushion rubber body of silicone rubber material is used for sealing, and the teflon clad has been used for lubricating, solvent-proof corrosivity, and its chemical property and Applicable scope are optimized greatly.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; In form with on the details the utility model is made various variations, be the protection domain of the utility model.

Claims (2)

1. a seal ring comprises the cushion rubber body, it is characterized in that, said cushion rubber body is outside equipped with the teflon clad.
2. a kind of seal ring according to claim 1 is characterized in that, the sectional shape of said cushion rubber body is irregularly shaped, semicircle, circle or rectangle.
