Further perfecting, the extrusion ring is circumferentially distributed with guide holes, the annular groove is circumferentially distributed with guide posts, and the guide holes are in sealing sliding connection with the guide posts.
Further perfecting, sealing flanges are arranged on the inner side and the outer side of the upper end of the extrusion ring.
Further perfecting, the bottom of the extrusion ring is provided with an inner conical surface, the bottom of the annular groove is provided with an outer conical surface, and the inner conical surface and the outer conical surface are parallel to each other.
Further perfecting, the upper side of the rubber ring body is provided with two sealing felt gaskets, and the extrusion ring is positioned between the two sealing felt gaskets.
The beneficial effects of the utility model are as follows: compared with the prior art, after the rubber ring body receives the extrusion, the extrusion ring promotes in to the annular groove, waterproof sealing grease extrudees to annular seal slot from the intercommunicating pore on, seals and lubricates between internal thread seal section and the screw rod, has improved the life of sealing washer, and the rubber ring body outwards expands and presses tightly with the inner wall laminating of pipeline simultaneously, effectually improved sealed effect.
Drawings
FIG. 1 is a schematic view of the present utility model in its installed use;
Reference numerals illustrate: 1. the sealing device comprises a rubber ring body, 2, an annular groove, 3, waterproof sealing grease, 4, a squeezing ring, 5, an internal thread sealing section, 6, an annular sealing groove, 7, a communication hole, 8, a guide hole, 9, a guide pillar, 10, a sealing flange, 11, an inner conical surface, 12, an outer conical surface, 13, a sealing felt gasket, 14, a screw, 15, a gland, 16 and a seat body.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
Referring to fig. 1: the rubber sealing ring comprises a rubber ring body 1, an annular groove 2 is formed in the upper side face of the rubber ring body 1, waterproof sealing grease 3 is filled in the annular groove 2, a squeezing ring 4 is arranged on the annular groove 2 in a sealing sliding mode, an inner thread sealing section 5 is arranged on an inner hole of the rubber ring body 1, an annular sealing groove 6 is formed in the inner thread sealing section 5, and a communication hole 7 is formed between the annular sealing groove 6 and the annular groove 2.
The pedestal 16 is a part of a pipeline or a valve body, the pedestal 16 is provided with a counter bore, the pedestal 16 is in threaded connection with the gland 15, the pedestal 16 or the gland 15 is in threaded connection with the screw rod 14, when the sealing device is used, the rubber ring body 1 is fixedly arranged between the pedestal 16 and the gland 15, the screw rod 14 is in threaded connection with the internal thread sealing section 5, the gland 15 is rotated during installation, the gland 15 moves downwards under the action of the threads to press the extrusion ring 4 downwards, the extrusion ring 4 is pressed into the annular groove 2, waterproof sealing grease 3 in the extrusion ring is extruded into the annular sealing groove 6 through the communication hole 7 to realize sealing and lubrication, the sealing performance between the screw rod and the rubber ring body is enhanced, meanwhile, the rubber ring body 1 is radially deformed and tightly pressed from the inner wall fitting of the pipeline, and the sealing effect is effectively improved. The rubber ring body 1 and the extrusion ring 4 are made of elastic rubber materials, so that a long-time sealing effect can be achieved.
The extrusion ring 4 is circumferentially distributed with guide holes 8, the annular groove 2 is circumferentially distributed with guide posts 9, the guide holes 8 are in sealing sliding connection with the guide posts 9, the extrusion ring 4 can move on the annular groove 2 more stably through the cooperation of the guide holes 8 and the guide posts 9, and the phenomenon that waterproof sealing grease 3 leaks due to deviation when the extrusion ring 4 moves is avoided.
The sealing flanges 10 are arranged on the inner side and the outer side of the upper end of the extrusion ring 4, so that the contact area between the sealing flanges and the gland 15 can be increased, the stress is more uniform, and the upper end of the extrusion ring 4 is not easy to collapse.
