Abstract
The invention provides a stably compressed end surface sealing gasket, which comprises a sealing body, one side of the sealing body is provided with double raised fixing retainer rings which are used for matching with grooves on a part, and the double fixing retainer rings are two rectangular projections which are arranged in parallel. The sealing body comprises a cylindrical part and a circular arc-shaped part integrated with one side of the cylindrical part. The stably compressed end surface sealing gasket has the following advantages: the cylindrical part play a main sealing role, the circular arc-shaped part plays an auxiliary sealing role while playing an installation-guiding role, consequently, end surface sealing is more reliable, and installation is more convenient; the double fixing retainer rings ensure that the sealing gasket cannot come off and shift in the process of assembly installation, thus solving the problem of unstable sealing caused by installation; the practicability is high.
Description
Technical field
The invention belongs to sealing configuration technical field, especially relate to a kind of stable compression end face seal pad and spherical joint end face seal structure.
Background technique
Sealing gasket is a kind of obturator generally adopted in mechanical structure, and it utilizes own form to seal, and structure is simple, but easily tightens in assembly process at compressing member and come off, be shifted, causes sealing configuration instability.
The line style ring-like contact band that the spherical joint sphere of ball shaped joint construction and screw-in structure taper hole are formed, i.e. sealing strip, sealing effect is unstable, especially high-power diesel engine work under bad environment, in the larger situation of complete machine oscillation, in actual use, often there is the leakage of medium, pollute engine room, even cause serious consequences such as catching fire.
Summary of the invention
In view of this, the problem to be solved in the present invention is to provide a kind of stable compression end face seal pad and spherical joint end face seal structure.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of stable compression end face seal pad, comprise sealed body, a side of described sealed body is provided with the two fixed card rings for the protrusion coordinated with the draw-in groove on part, and described pair of fixed card ring is two rectangular preiections be arranged in parallel.
Further, described sealed body comprises the circular arc portion of column part and side one.
Further, described sealed body is quality of rubber materials.
The present invention stablizes and compresses advantage that end face seal spacer has and good effect is:
Column part plays main seal effect, circular arc portion also serves the effect of auxiliary seal while having installation leading role, make end face seal more reliable, install more convenient, two fixed card ring ensures that sealing gasket does not come off in component mounting process, displacement etc., solve owing to installing the sealing unstable problem caused, practicability is stronger.
A kind of spherical joint end face seal structure using aforementioned stable to compress end face seal pad, comprise and screw in joint, spherical joint and gland nut, the outer spherical head of described spherical joint inserts in the internal tapered hole screwing in joint, and gland nut is enclosed within the outside screwing in joint and spherical joint; Described spherical joint outer side surface is provided with two grooves arranged side by side near the position of outer exterior edge face; Be provided with between described gland nut interior edge face and spherical joint exterior edge face to stablize and compress end face seal pad, described pair of fixed card ring embeds groove arranged side by side, described column part contacts with the inner side surface of gland nut, described circular arc portion and the chamfering of interior edge face coordinating gland nut.
The advantage that spherical joint end face seal structure of the present invention has and good effect are:
Column part plays main seal effect, and circular arc portion also serves the effect of auxiliary seal while having installation leading role, makes end face seal more reliable, installs more convenient.Two fixed card ring ensures that sealing gasket does not come off in component mounting process, displacement etc., solves the sealing reliability problem of ball shaped joint construction, prevents the leakage of medium.
