Abstract
The utility model relates to a seal gasket. Mainly for solving seal gasket expansibility poor, corrosion resisting property is poor, the not ideal problem of sealed effect inadequately. The newly designed sealing gasket is an integral structure formed by a sealing ring and partition bars, the partition bars are arranged and combined in the sealing ring, the sealing ring is a sandwich structure of two clamping pieces, and the middle filler is a rubber asbestos plate.
Description
The utility model relates to gasket seal.
Existing polytetrafluoroethylene sealing gasket sheet is because its action material is single, particularly structurally there is defective, therefore expansion character is poor, sealing effect is bad, when being used in fluid pipeline, the run, drip, leak phenomenon happens occasionally, and department brings many troubles to the equipment use, influences economic benefit and carries out production strictly in line with rules and regulations.
The purpose of this utility model structurally makes improvements at existing polytetrafluoroethylene sealing gasket sheet, overcomes the above-mentioned defective of its existence, designs a kind of gasket seal of corrosion-resistant strong good seal performance.
The purpose of this utility model is achieved in that newly-designed teflin tape parting bead interlayer gasket seal is the overall structure that seal ring and parting bead are formed, it is characterized in that being provided with in the seal ring circle parting bead of various permutation and combination, seal ring be two surface layers for interconnecting one-time formed teflon intermediate plate, intermediate filler layer is the sandwich structure of rubber asbestos plate.
Below the utility model is described in further detail by drawings and Examples:
Fig. 1 is one of the utility model embodiment plane structure schematic representation.
Fig. 2 is Fig. 1 A-A cutaway view Amplified image.
Fig. 3 is the utility model embodiment's two plane structure schematic representation.
Mark among the figure: 1. seal ring, 2. parting bead, 3. joint, 4. surface layer, 5. intermediate filler layer.
Seal ring 1 is the smooth overall structure of sealing surface as shown in drawings; Parting bead and seal ring joint are the dovetail groove bonded structure; Parting bead is by making with the smooth teflon of seal ring same thickness.
The utility model not only has high-low temperature resistant, corrosion resistance, and has certain rigidity and mechanical strength through on probation, good integrity, expansion character is good, and sealing effect is more satisfactory, can make the not profiled spacer of various different sizes, be widely used in departments such as oil, chemical industry, metallurgy, pharmacy.
Claims (2)
1, teflin tape parting bead interlayer gasket seal, overall structure for seal ring and parting bead composition, it is characterized in that being provided with in the seal ring circle parting bead of various permutation and combination, seal ring be two surface layers for interconnecting one-time formed teflon intermediate plate, intermediate filler layer is the sandwich structure of rubber asbestos plate.
2, teflin tape parting bead interlayer gasket seal as claimed in claim 1, it is characterized in that seal ring is the smooth overall structure of sealing surface, parting bead and seal ring joint are the dovetail groove bonded structure, and parting bead is by making with the smooth teflon of seal ring same thickness.
