Based on this, the utility model aims to provide a silica gel sealing joint to solve the technical problems that sealing is realized by extruding a sealing ring through a threaded joint, so that the sealing effect is poor, and meanwhile, the service life of the sealing ring is short due to the fact that the sealing ring is exposed outside.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a silica gel sealing joint, includes main joint and pipeline, both ends in the main joint all are provided with the mounting groove, the inside passageway that link up two mounting grooves that is provided with of main joint, the outside one end of mounting groove inner wall is provided with the internal thread, the main joint has the sealing washer through spout sliding connection, the inner of mounting groove is provided with hollow rubber circle, the outside of pipeline is provided with protruding structure, and this protruding structural external screw thread that is provided with.
Through adopting above-mentioned technical scheme, set up the sealing washer in the main joint, can prevent that the sealing washer from exposing outside, cause the life-span to reduce, cooperate with the internal thread of main joint through the external screw thread of boss, realize fixing the pipeline, the sealing washer is once sealed, and the sealing washer can form the extrusion to hollow core rubber circle, makes hollow core rubber circle take place deformation to this clearance of filling between sealing washer and the spout carries out secondary seal.
The utility model is further provided that the slide groove is located inside the internal threaded portion.
Through adopting above-mentioned technical scheme, when preventing that the external screw thread of pipeline department from advancing, cause destruction to the spout to destroy its leakproofness.
The utility model is further provided that the inner diameter of the opening of the sealing ring is equal to the inner diameter of the channel.
Through adopting above-mentioned technical scheme, when the liquid in the passageway passes through, can prevent that the sealing washer from blockking it, causing the inside jam of passageway, reducing its velocity of flow.
The utility model is further arranged that the cross section of the hollow rubber ring is in a D-shaped structure.
By adopting the technical scheme, when the sealing ring extrudes the hollow rubber ring, the hollow rubber ring can be deformed, and the gap between the hollow rubber ring and the hollow rubber ring can be conveniently filled.
In summary, the utility model mainly has the following beneficial effects:
according to the utility model, the sealing ring is arranged in the main joint, so that the sealing ring can be prevented from being exposed outside, the service life is shortened, when the pipeline is inserted into the main joint, the sealing ring is sleeved on the pipeline and pushed forwards through the pipeline, and then the pipeline is fixed through the matching of the external thread of the boss and the internal thread of the main joint, the sealing ring is sealed for the first time, the sealing ring can extrude the hollow rubber ring, so that the hollow rubber ring is deformed, and the gap between the sealing ring and the sliding chute is filled for the secondary sealing, and the sealing effect is ideal.
