Description

Anti-falling rubber sealing ring

Technical Field

The utility model belongs to the technical field of the sealing washer, a anticreep type rubber seal is related to.

Background

The rubber seal ring is an annular cover composed of one or more parts, is fixed on one ferrule or gasket of a bearing or other to-be-sealed member, and is contacted with another ferrule or gasket or forms a narrow labyrinth gap to prevent lubricating oil or other media from leaking out and foreign matters from entering.

For the pipeline joint, the phenomenon that the sealing ring slides under the action of pressure easily occurs for a long time in consideration of the pressure bearing of the sealing ring, so that the sealing is not in place.

Fig. 1 illustrates a sealing ring structure in a conventional pipeline connection, a pipeline 01 is inserted into a pipeline connector 02 at the other end, a thread is arranged outside the pipeline connector 02, the pipeline 01 is tightly matched with the sealing ring, a pipeline connector 03 is screwed outside the pipeline connector 02, the sealing ring includes a butting ring 041 and a deformation sealing ring 042, and the butting ring 041 can butt against the deformation sealing ring 042 to deform the deformation sealing ring 042 to seal the pipeline through the screwing clamping effect of the pipeline connector 03 and the pipeline connector 02.

But because liquid pressure and water hammer effect in the pipeline can strike the sealing washer for a long time, make it produce unrecoverable deformation ageing, can produce the clearance, and then the sealing washer easily slides, drops, and the anticreep effect reduces, and the pipeline is because the effort with the sealing washer reduces simultaneously, also probably leads to not hard up the separation because of the vibration, and then produces easily and leaks.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 2-3, a anticreep type rubber seal, including butt circle 1 and high-elastic circle 2, butt circle 1 and high-elastic circle 2 laminate pipe connector and pipe joint respectively, when the assembly, can give butt circle 1 and high-elastic circle 2 with inside effort between pipe joint and the pipe connector, form the sealed to the pipeline, install elastic component 3 in butt circle 1's inboard, elastic component 3 laminates the pipeline setting, with behind the bolted connection power of applying the horizontal direction, can make butt circle 1 outside protruding, and correspond elastic component 3 and installed joint 4 in butt circle 1 outer end side, strengthen the effort of butt circle 1 outside protruding back and pipe joint inner wall.

In particular, the method comprises the following steps of,

a butting groove 12 is formed in the inner side of the butting ring 1, the elastic piece 3 is embedded in the butting groove 12, and the height of the elastic piece 3 is basically flush with the inner wall of the butting ring 1; a plurality of deformation grooves 11 are formed in the outer side of the abutting ring 1 corresponding to the elastic piece 3, and the clamping piece 4 is arranged in the deformation grooves 11; the snap-in elements 4 are preferably inserted at intervals in the deformation slots, the height of which, when not compressed, is substantially flush with the outside of the abutment ring 1.

When the device is installed, the elastic piece 3 can deform along the radial direction under stress, and then the abutting ring is jacked outwards to deform the arc shape, so that the deformation groove 11 expands outwards and the clamping piece 4 is jacked out, and the elastic piece 3 can resist the instantaneous impact of liquid to effectively protect the joint; simultaneously, the joint spare 4 that the interval set up, after deformation groove 11 expands outward, still can with the screw-thread fit on the pipe joint, also can increase the anticreep ability.

In this example, the elastic member 3 is a spring for a seal ring. The clamping piece 4 can be an arc-shaped metal sheet or a metal ring with a gap.

In order to increase the sealing capacity, a groove 13 is formed in the lip of the abutting ring 1 (namely, the left side in fig. 3), so that after stress (mainly rightward acting force) is applied, the lip can be bent and deformed along two sides of the groove 13, and further the sealing performance is increased;

similarly, the inclined lip of the high elastic ring 2 is provided with an outward-expanding groove 21, and the extrusion force of the pipeline joint can generate corresponding acting force to the lip at the inclined lip, so that the inclined lip of the high elastic ring 2 can be bent and deformed along the outward-expanding groove 21.

In consideration of low-temperature tolerance, the abutting ring 1 and the high elastic ring 2 are made of silicon rubber materials and have good high-low temperature tolerance. The higher the hardness of the abutment ring 1 is, the greater the hardness of the elastic ring 2.
