Abstract
A novel sealing expansion joint is characterized by comprising a connector body. Expansion openings are formed in the connector body. Each expansion opening is internally provided with an installation groove. Each installation groove is internally provided with a sealing lantern ring. Each sealing lantern ring is provided with a pressing ring. A pipeline is inserted into the connector body to make contact with the inner walls of the sealing lantern rings. The pipeline is fixedly connected with the connector body through fastening nuts. The height L of each installation groove ranges from 30mm to 50mm. The height H of each sealing lantern ring ranges from 20mm to 40mm. The contact surface between the sealing lantern rings and the expansion joint and the contact surface between the sealing lantern rings and the pipeline are increased by increasing the heights of the installation grooves and the heights of the sealing lantern rings, so that the sealing performance between the sealing lantern rings and the expansion joint and between the sealing lantern rings and the pipeline is improved. Meanwhile, when the pipeline is heated to extend or cooled to retract, the heightened sealing lantern rings can be kept in sealing fit with the pipeline all the time, and the sealing performance and the using effect of the expansion joint are ensured.
Description
Technical field
The utility model relates to a kind of novel seal slip joint.
Background technique
Plastic tube, when being used as the delivery line of long distance, is to ensure pipe safety operation, and compensation pipeline axial, horizontal, the dilatation of angle because being heated or catching a cold and causing, need to a lot of pipelines is sectional couple together by slip joint.At slip joint inwall, all seal ring can be set, by seal ring and tube contacts, pipeline and slip joint are reached to be sealed and matched, and the seal ring mounting groove of existing slip joint inwall is shallow, the seal ring of installing is thinner, and the surface of contact of seal ring inwall and pipeline is few, sealing is poor, and when pipeline is heated or catches a cold, cause after dilatation, easy and seal ring disengages, and affects using effect.
Summary of the invention
The purpose of this utility model is the shortcoming existing in order to overcome prior art, a kind of height that increases mounting groove height and sealing ring is provided, sealing ring and tube contacts face are increased, good seal performance, a kind of novel seal slip joint still coordinating with seal for pipe joints after dilatation.
The technological scheme of a kind of novel seal slip joint of the utility model is: it is characterized in that comprising fittings body, on fittings body, be shaped with enlarging, in enlarging, be shaped with mounting groove, sealing ring is set in mounting groove, pressure ring is set on sealing ring, and pipeline inserts fittings body and contacts with sealing ring inwall, and pipeline and fittings body fix through tightening nut, the height L of described mounting groove is 30-50mm, and the height H of sealing ring is 20-40mm.
The utility model discloses a kind of novel seal slip joint, by increasing the height of mounting groove and the height of sealing ring, the surface of contact of sealing ring and slip joint and pipeline is increased, thereby improve the sealability between sealing ring and slip joint and pipeline, and when pipeline is subject to thermal stretching or catches a cold shortening, the sealing ring increasing can keep being sealed and matched with pipeline all the time, guarantees sealability and the using effect of slip joint.
A kind of novel seal slip joint of the utility model, is shaped with interior inclined-plane between described fittings body and enlarging, be shaped with Yu Wai inclined-plane, ，Nei inclined-plane, outer inclined-plane and contact under sealing ring, at tightening nut inwall, is shaped with retainer ring, contacts below retainer ring with pressure ring.After inserting pipeline, tighten tightening nut, the retainer ring of tightening nut pushes pressure ring downwards, and the downward crush seal collar of pressure ring makes the outer inclined-plane of sealing ring tighten along interior inclined-plane downwards and inwardly, thereby makes better tightness between sealing ring and pipeline.Described fittings body outer wall is shaped with stiffening rib, improves the intensity of fittings body.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of novel seal slip joint of the utility model;
Fig. 2 is the structural representation of fittings body.
Embodiment
The utility model relates to a kind of novel seal slip joint, as shown in Fig. 1-Fig. 2, it is characterized in that comprising fittings body 1, on fittings body, be shaped with enlarging 2, in enlarging, be shaped with mounting groove 3, sealing ring 4 is set in mounting groove, pressure ring 5 is set on sealing ring, and pipeline 6 inserts fittings body 1 and contacts with sealing ring 4 inwalls, and pipeline and fittings body fix through tightening nut 7, the height L of described mounting groove 3 is 30-50mm, and the height H of sealing ring 4 is 20-40mm.By increasing the height of mounting groove 3 and the height of sealing ring 4, the surface of contact of sealing ring and slip joint and pipeline 6 is increased, thereby improve the sealability between sealing ring 4 and slip joint and pipeline, and when pipeline is subject to thermal stretching or catches a cold shortening, the sealing ring increasing can keep being sealed and matched with pipeline 6 all the time, guarantees sealability and the using effect of slip joint.Between described fittings body 1 and enlarging 2, be shaped with interior inclined-plane 8, sealing ring is shaped with outer inclined-plane 9 for 4 times, and Yu Wai inclined-plane, interior inclined-plane contacts, and at tightening nut 7 inwalls, is shaped with retainer ring 10, contacts below retainer ring with pressure ring 5.After inserting pipeline 6, tighten tightening nut 7, the retainer ring 10 of tightening nut is extruding pressure ring 5 downwards, the downward crush seal collar 4 of pressure ring, the outer inclined-plane 9 of sealing ring is tightened downwards and inwardly along interior inclined-plane 8, thereby make better tightness between sealing ring and pipeline 6.Described fittings body 1 outer wall is shaped with stiffening rib 11, improves the intensity of fittings body 1.
