Abstract
The utility model relates to the forced locking seal ring of a kind of pipeline, it is characterized in that: comprise an endless metal skeleton, the cross section of described endless metal skeleton is corrugated, rubber sleeve is become in skeleton upper and lower end end and the coaxial integrated injection molding of inside and outside edge, on the rubber sleeve of described skeleton outer rim one end, coaxially integrally making a radially outer periphery is fitted together to bulge loop, and periphery is fitted together to rubber sleeve Inner edge corresponding to bulge loop and is integrally shaped with radially inner inner sleeve termination locking ring.The skeleton of the pipeline that the utility model provides forced locking seal ring is corrugated, supporting of this corrugated skeleton is stronger, there is powerful anti-extrusion and bending ability, effectively prevent the seal ring generation deformation in storage and transportation process, simultaneously, ripple type has squeezing property to sealing, effectively can strengthen sealing.
Description
Technical field
The utility model belongs to pipe coupling field of components, the forced locking seal ring of especially a kind of pipeline.
Background technique
Current municipal water pipe is iron pipe, the inside and outside all raw full iron rust of Long-Time Service, pipeline very easily corrodes, poor durability, the proportion of iron pipe is heavier, the installation of long distance and the man power and material of transport at substantial, and the water delivery of the isometric distance of the such as south water to north adopts iron pipe, it is very difficult to change, and causes the waste of resource and manpower unavoidably.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of good sealing effect, structure simple, install and change the forced locking seal ring of pipeline easily.
The technological scheme that the utility model realizes object is as follows:
The forced locking seal ring of a kind of pipeline, comprise an endless metal skeleton, the cross section of described endless metal skeleton is corrugated, rubber sleeve is become in skeleton upper and lower end end and the coaxial integrated injection molding of inside and outside edge, on the rubber sleeve of described skeleton outer rim one end, coaxially integrally making a radially outer periphery is fitted together to bulge loop, and periphery is fitted together to rubber sleeve Inner edge corresponding to bulge loop and is integrally shaped with radially inner inner sleeve termination locking ring.
And parallel slow indent is coaxially integrally made respectively in the described upper and lower both sides at inner sleeve termination locking ring.
The beneficial effects of the utility model are:
1, the pipeline forced locking seal ring that the utility model provides has passive steel hoop skeleton, become to have rubber sleeve at Framework Of Steel Reinforcement periphery integrated injection molding, rubber sleeve is integrally shaped with the embedding bulge loop of inner sleeve termination locking ring and periphery, also be shaped with the slow indent for releasing the pressure simultaneously, this seal ring can realize sealing and the tightness of two conduit connection end heads, ensure the sealing effect of pipeline use in term, the leakage of water or other liquid can not be caused, contribute to the long-term of pipeline or super-long-term use.
2, the pipeline forced locking seal ring that the utility model provides is a kind of elastic seal ring being applicable to plastic pipe, when plastic pipe is made, one is coaxially inlaid in one end of pipeline, its pipeline the other end sidewall is shaped with the corresponding bulge loop joint to the coaxial setting-in of sealing circle, ensure that two pipelines after connecting can not depart from each other, because seal ring has rubber sleeve, rubber has certain elastic strain, the sealing of plastic pipe joint can be ensured for a long time, ensure using effect.
3, the skeleton of pipeline forced locking seal ring that the utility model provides is corrugated, supporting of this corrugated skeleton is stronger, there is powerful anti-extrusion and bending ability, effectively prevent the seal ring generation deformation in storage and transportation process, simultaneously, ripple type has squeezing property to sealing, effectively can strengthen sealing.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 be in Fig. 1 A-A to sectional view;
Fig. 3-Fig. 6 is other embodiment's cross-sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
The forced locking seal ring of a kind of pipeline, comprise an endless metal skeleton 4, the cross section of described endless metal skeleton is corrugated, rubber sleeve 1 is become in skeleton upper and lower end end and the coaxial integrated injection molding of inside and outside edge, on the rubber sleeve of described skeleton outer rim one end, coaxially integrally making a radially outer periphery is fitted together to bulge loop 2, periphery is fitted together to rubber sleeve Inner edge corresponding to bulge loop and is integrally shaped with radially inner inner sleeve termination locking ring 3, coaxially integrally makes parallel slow indent 5 respectively in the upper and lower both sides of inner sleeve termination locking ring.
As shown in figures 3 to 6, the structure that its periphery is fitted together to bulge loop, inner sleeve termination locking ring and two parallel slow indents can make suitable change according to the shape of actual pipeline and internal diameter to other structures of the present utility model.
The pipeline that the utility model provides forced locking seal ring has passive steel hoop skeleton, become to have rubber sleeve at Framework Of Steel Reinforcement periphery integrated injection molding, rubber sleeve is integrally shaped with the embedding bulge loop of inner sleeve termination tight lock part and periphery, also be shaped with the slow indent for releasing the pressure simultaneously, this seal ring can realize sealing and the tightness of two conduit connection end heads, ensure the sealing effect of pipeline use in term, the leakage of water or other liquid can not be caused, contribute to the long-term of pipeline or super-long-term use.
