Abstract
The utility model belongs to a multistage torque controllable nonmetallic gasket which comprises an annular body, wherein the annular body is composed of annular rings, and the thicknesses of the annular rings decrease in a gradient mode. The annular rings can be controlled to be conveniently arranged according to the different thicknesses of the gaskets and according to the requirements of the leakage rate or the requirements of different pressure grades. The edge of the annular body is of a horizontal structure. The surface of a connecting piece is prevented from damage. The thickness of the annular body decreases in the gradient mode from outside to inside. The sealing effect of the multistage torque controllable nonmetallic gasket is made to be better.
Description
Technical field
The utility model belongs to the controlled nonmetallic gasket of multistage moment of torsion.
Background technique
Pad is two mechanical seals between the object, and paper using, rubber tissue or copper sheet are made, and is to be placed between two planes with the material of enhanced leaktightness, is arranged on the seal element between the static seal face for preventing fluid leakage.Because machining surface can not be perfect, use pad can fill up irreqularity, pad is made by sheet material usually.Select the material of pad to depend primarily on following three kinds of factors: the temperature, pressure medium.Pad comprises metallic shim, semi-metallic gasket and nonmetallic gasket.Nonmetallic gasket is with nonmetal pads of making such as asbestos, rubber, synthetic resin, teflon.For nonmetallic gasket, need well control bolt torque guarantee sealing effect during installation.But because installer's technical ability own and field condition limit, the phenomenon of the inadequate or excessive conquassation of moment of torsion often can appear.Need a kind of easy-to-operat, the nonmetallic gasket that convenient control is installed.
Summary of the invention
The utility model is not enough for prior art, and a kind of easy-to-operat is provided, the nonmetallic gasket that convenient control is installed.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: the controlled nonmetallic gasket of multistage moment of torsion, comprise ring body, and described ring body is comprised of the annular ring that thickness descends in gradient.Can according to the requirement of leak-down rate or pressure rating otherwise with, can control easily installation by different spacer thicknesses.
In the technique scheme, described ring body edge is horizontal structure.Prevent from the coupling surface is damaged.
In the technique scheme, described ring body tow sides are the annular ring that thickness descends in gradient.Tow sides have identical structure, have avoided the staff carefully to check pad acting surface institute's time spent, promote working efficiency.
In the technique scheme, described ring body comprises a part, No. two parts and No. three parts, and a described part is the inclined-plane with No. two part joints, and described No. two parts are the inclined-plane with No. three part joints.Play the effect of protection pad, each several part joint cracking increases the service life when preventing that pad is stressed.
In the technique scheme, be 30 ° of angles between the inclined-plane of a described part and No. two part joints and the vertical plane, be 30 ° of angles between described No. two parts and No. three inclined-planes of being connected of part and the vertical plane.Angle is larger, and the inclined-plane is longer, and the material that needs is more, is 30 ° of angles between inclined-plane and the vertical plane and can either protects pad, again can economical with materials.
In the technique scheme, described ring body ecto-entad thickness descends in gradient.Make the gasket seal better effects if.
The utility model compared with prior art has following beneficial effect: the utility model can according to the requirement of leak-down rate or pressure rating otherwise with, can control easily installation by different spacer thicknesses.Can prevent from the coupling surface is damaged.Tow sides have identical structure, have avoided the staff carefully to check pad acting surface institute's time spent, promote working efficiency.The each several part joint is the effect that the inclined-plane plays the protection pad, and each several part joint cracking increases the service life when preventing that pad is stressed.Angle is larger, and the inclined-plane is longer, and the material that needs is more, is 30 ° of angles between inclined-plane and the vertical plane and can either protects pad, again can economical with materials.Ring body ecto-entad thickness descends in gradient, makes the gasket seal better effects if.
Description of drawings
Fig. 1 is the utility model schematic representation.
Fig. 2 is the utility model schematic cross-section.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: referring to Fig. 1 and Fig. 2, the controlled nonmetallic gasket of multistage moment of torsion comprises ring body 1, and described ring body 1 is comprised of the annular ring that thickness descends in gradient.Can according to the requirement of leak-down rate or pressure rating otherwise with, can control easily installation by different spacer thicknesses.
Described ring body 1 edge is horizontal structure.Prevent from the coupling surface is damaged.
Described ring body 1 tow sides are the annular ring that thickness descends in gradient.Tow sides have identical structure, make things convenient for the placement of pad.
Described ring body 1 comprises a part 3, No. two parts 4 and No. three parts 5, and a described part 3 and No. two part 4 joints are the inclined-plane, and described No. two parts 4 and No. three part 5 joints are the inclined-plane.Play the effect of protection pad, each several part joint cracking increases the service life when preventing that pad is stressed.
Be 30 ° of angles between the inclined-plane of a described part 3 and No. two part 4 joints and the vertical plane, be 30 ° of angles between the inclined-plane that described No. two parts 4 are connected with No. three parts 5 and the vertical plane.Angle is larger, and the inclined-plane is longer, and the material that needs is more, is 30 ° of angles between inclined-plane and the vertical plane and can either protects pad, again can economical with materials.
Described ring body 1 ecto-entad thickness descends in gradient.Make the gasket seal better effects if.
The dynamics that use the different position of the utility model thickness on ring body is the dynamics of setting after the experiment.During installation, different according to the requirement of the requirement of leak-down rate or pressure rating, select pad is pressed onto accurately thickness, solved originally the technical ability of operator own and field condition and limit, the phenomenon of the inadequate or excessive conquassation of the moment of torsion of appearance.
