Abstract
A self-strengthening soft bustle pipe gasket seal comprises a ringed metallic bustle pipe and a cladding covered on the upper surface and lower surface of the metallic bustle pipe, wherein, the pipe wall of the metallic bustle pipe is provided with a pressure guiding hole communicated with a pipe chamber, and the diameter of the pressure guiding hole ranges from 0.1 to 10 millimeters. The arrangement of the pressure guiding hole guides the pressure in a pipeline into the pipe chamber of the metallic bustle pipe through the pressure guiding hole when the gasket seal is arranged between a pipeline and a flange. The pressure of medium is used to realize the self-strengthening effect of the gasket seal, to stabilize the sealing pressure and increase the adaptive ability of the soft gasket seal.
Description
Technical field
The utility model relates to a kind of gasket seal, relates in particular to a kind of flexible ring tube sealing pad.
Background technique
In the prior art, gasket seal is many to be made with flexible material, for example asbestos, rubber etc., because the ability that this kind material meets with stresses is relatively poor, in use for some time, owing to bear the effect of pressure and ambient temperature, gasket seal is easily aging or lax, sealing variation even lose sealability, flexible when mounted distortion has simultaneously influenced sealing effect.The gasket seal that other has metallic material to make, limited because of metal tube material compression recovery performance, Applicable scope is narrower.
Summary of the invention
The utility model purpose provides a kind of self-reinforcing flexible ring tube sealing pad, and its adaptive capacity is stronger.
The technical solution of the utility model is: a kind of self-reinforcing flexible ring tube sealing pad, it comprises the metal endless tube of ring-type, the upper surface that covers described metal endless tube and the coating on the lower surface, have the pressure guide hole that is connected with its tube chamber on the tube wall of described metal endless tube, the bore dia of described pressure guide hole is 0.1～10 millimeter.
In a kind of optimized project of the present utility model, fixedly install restricted interior ring on the inner circumferential surface of described metal endless tube, the thickness of ring is 0.5～20 millimeter in the described restriction, width is 1～100 millimeter.Also can fixedly install the restriction outer shroud on the external peripheral surface of described metal endless tube, the thickness of described restriction outer shroud is 0.5～20 millimeter, and width is 1～100 millimeter.Ring and restriction outer shroud are in the both sides of metal endless tube respectively in the restriction, laterally the metal endless tube is being played spacing reinforing function, simultaneously, when coating meets with pressure and makes whole gasket seal when vertically being compressed, limit the interior ring of outer shroud and restriction and play the prevention gasket seal by the effect of excess compression.
The outer tube diameter of described metal endless tube is 1～300 millimeter, and the wall thickness of described metal endless tube is 0.1～10 millimeter.
Pressure guide hole on the described metal endless tube has 1～5000.
Described coating protrudes 0.1～20 millimeter on the surface of metal endless tube.
The surface of described coating is plane, toothed surface or arc surface.
The utility model has the advantages that: the offering of pressure guide hole, make when the installation of this gasket seal is applied between the piping flange, pressure in the pipeline can import in the tube chamber of metal endless tube through pressure guide hole, realize the self-strengthening of gasket seal to utilize pressure medium, stablize its seal pressure, improve the adaptive capacity of this flexible sealing gasket pressure medium variation and the variation of sealing surface external force.
Description of drawings
Accompanying drawing 1 is a plan view of the present utility model;
Accompanying drawing 2 is the enlarged view at the I place in the accompanying drawing 1;
Wherein: 1, metal endless tube; 2, pressure guide hole; 3, coating; 4, ring in the restriction; 5, restriction outer shroud.
Embodiment
Shown in Fig. 1-3, the utility model relates to a kind of self-reinforcing flexible ring tube sealing pad, it comprises the metal endless tube 1 of ring-type, the upper surface that covers described metal endless tube 1 and the coating on the lower surface 3, the outer tube diameter of described metal endless tube 1 is 1～300 millimeter, and the wall thickness of described metal endless tube 1 is 0.1～10 millimeter.The surface of described coating 3 is plane, toothed surface or arc surface, and described coating 3 protrudes 0.1～20 millimeter on the surface of metal endless tube 1.
The upper and lower surface of sealing pad is its sealing surface; coating 3 promptly is on the sealing surface; when using installation; gasket seal is between the flange of butt joint pipeline; coating 3 contacts with piping flange; play the effect of seal action and protection metal endless tube 1, this is common installation method, does not adopt accompanying drawing to give unnecessary details at this.
Be the rigidity of enhanced leaktightness pad, fixedly install restricted outer shroud 5 on the external peripheral surface of described metal endless tube 1, the thickness of described restriction outer shroud 5 is 0.5～20 millimeter, and width is 1～100 millimeter.Also fixedly install restricted interior ring 4 on the inner circumferential surface of described metal endless tube 1, the thickness of ring 4 is 0.5～20 millimeter in the described restriction, and width is 1～100 millimeter.Ring 4 and restriction outer shroud 5 are in the interior outside of metal endless tube 1 respectively in the restriction, it is at the interior outside of metal endless tube 1 banding metal endless tube 1, can be in laterally restriction metal endless tube 1 deformation, and vertically, when ring 4 or restriction outer shroud 5 are fair in coating 3 and metal endless tube 1 are compressed to height and restriction, the restriction of ring 4 and restriction outer shroud 5 in degree by compression then is restricted, thus make gasket seal avoid by excess compression deformation even be crushed.
Have 1～5000 pressure guide hole 2 that is connected with the tube chamber of metal endless tube 1 on the tube wall of described metal endless tube 1, the bore dia of described pressure guide hole 2 is 0.1～10 millimeter, sees Fig. 2 and shown in Figure 3.In the embodiment shown in fig. 1, pressure guide hole 2 has eight, and these pressure guide holes 2 are arranged along the circumferencial direction of metal endless tube 1, see shown in Figure 1.All offer pressure guide hole 2 on the upside tube wall of metal endless tube 1 and the downside tube wall, each pressure guide hole 2 all is positioned at the inner circumferential surface place near metal endless tube 1, and is in outside the zone that coating 3 covered.When being installed in the sealing pad between the piping flange, pressure in the pipeline can import in the tube chamber of metal endless tube 1 through pressure guide hole 2, with increase metal endless tube 1 intraluminal pressure, thereby the seal pressure of stabilized seal pad is realized self-strengthening to utilize pressure medium.
