Abstract

For the non-metallic gasket sealed, comprise a cylinder component be made up of nonmetallic material, be coaxially arranged with a cylindrical hole in cylinder component, the periphery of the upper-end surface of cylinder component is provided with the hoop flange raised up.The inwall of hoop flange is the conical surface.The periphery of the lower end surface of cylinder component is provided with the hoop flange to lower convexity.Hoop flange to lower convexity is symmetrical with the hoop flange raised up.The utility model is provided with protruding hoop flange at the periphery of the end face of non-metallic gasket, and at two pipe fittings be threaded when connecting, gasket deforms enters and fills the gap of internal and external threads, adds sealing surface, improves sealing effect.

Description

For the non-metallic gasket sealed
Technical field:
The utility model relates to mechanical field, particularly relates to piping element, particularly a kind of non-metallic gasket for sealing.
Background technique:
Non-metallic gasket, the packing ring be such as made up of rubber or nylon material, is widely used in pipe-line system, between the end face especially for two pipe fittings be threaded connection, to seal the junction surface of two pipe fittings.In prior art, non-metallic gasket is faced washer, and sealing surface is less, and sealing was easily lost efficacy.
Summary of the invention:
The purpose of this utility model is to provide a kind of non-metallic gasket for sealing, and the described this non-metallic gasket for sealing will solve the technical problem that non-metallic gasket sealing surface in prior art is less, sealing was easily lost efficacy.
This non-metallic gasket for sealing of the present utility model, comprise a cylinder component be made up of nonmetallic material, be coaxially arranged with a cylindrical hole in described cylinder component, wherein, the periphery of the upper-end surface of described cylinder component is provided with the hoop flange raised up.
Further, the inwall of described hoop flange is the conical surface.
Further, the periphery of the lower end surface of described cylinder component is provided with the hoop flange to lower convexity.
Further, the hoop flange raised up of the described hoop flange to lower convexity and upper-end surface is symmetrical.
Further, the inwall of the described hoop flange to lower convexity is the conical surface.
Working principle of the present utility model is: two pipe fittings be threaded are when connecting, screwing into of one end, the chamfer surface of this externally threaded end face periphery is tapered, the hoop flange of extruding non-metallic gasket end face projection, in the process continuing to screw, gasket deforms enters and fills the gap of internal and external threads, adds sealing surface.In the end face of another pipe fitting coordinated with male element, arrange a circumferential groove, the hoop flange of another end face projection of its radial position and non-metallic gasket coordinates, and can increase sealing area further, realize labyrinth sealing action.Non-metallic gasket upper and lower end face all arranges symmetrical hoop flange, anti-loaded when can avoid assembling.
The utility model is compared with prior art, and its effect is actively with obvious.The utility model is provided with protruding hoop flange at the periphery of the end face of non-metallic gasket, and at two pipe fittings be threaded when connecting, gasket deforms enters and fills the gap of internal and external threads, adds sealing surface, improves sealing effect.
Accompanying drawing illustrates:
Fig. 1 is the axial section structural representation of the non-metallic gasket for sealing of the present utility model.
Fig. 2 is the structural representation of an embodiment of the non-metallic gasket for sealing of the present utility model.
Embodiment:
Embodiment 1:
As shown in Figure 1, non-metallic gasket for sealing of the present utility model, comprise a cylinder component be made up of nonmetallic material 1, a cylindrical hole is coaxially arranged with in described cylinder component 1, wherein, the periphery of the upper-end surface of described cylinder component 1 is provided with the hoop flange 2 raised up.
Further, the inwall of described hoop flange 2 is the conical surface.
Further, the periphery of the lower end surface of described cylinder component 1 is provided with the hoop flange 3 to lower convexity.
Further, the described hoop flange 3 to lower convexity and the hoop flange 2 the raised up symmetry of upper-end surface.
Further, the inwall of the described hoop flange 3 to lower convexity is the conical surface.
As shown in Figure 2, the working principle of the present embodiment is: the pipe fitting 4 be threaded and pipe fitting 5 are when being connected, screwing into of pipe fitting 5, the chamfer surface of this externally threaded end face periphery is tapered, the hoop flange 2 of extruding non-metallic gasket end face projection, in the process continuing to screw, gasket deforms enters and fills the gap of internal and external threads, adds sealing surface.In the end face of the pipe fitting 4 coordinated with pipe fitting 5, arrange a circumferential groove 6, the hoop flange 3 of another end face projection of its radial position and non-metallic gasket coordinates, and can increase sealing area further, realize labyrinth sealing action.Non-metallic gasket upper and lower end face all arranges symmetrical hoop flange, anti-loaded when can avoid assembling.
